Blended cotton According to the different needs of customers, fiber cotton can be manufactured according to different formulas. After the initial proportioning is completed, it is poured into the mixer for rotation and mixing, so that various raw materials can be fully mixed. 2. Opening The fully and uniformly mixed fibers are slowly spread out and sent to the licker - in equipment used in the next process for opening. After passing through this process, the fiber mass is sent to the secondary opening equipment by the fan, and then sent to the mixing box by the fan for further mixing. 3. Organize Use reasonable equipment to process into a uniform thickness of cotton layer, and then transfer to the beginning, after shaking and laying into a mesh. 4. Laying the net In this step, the screen is shaken back and forth to form a uniform mesh layer, and then the bottom screen is sent to the oven. 5. Hot air setting At this time, the non woven filter fabric filter cotton should be fed into the oven with a uniform cotton layer, and the fiber cotton can be formed at a certain temperature. 6. Shaping & Trimming The next step is that the synthetic fiber cotton needs to be shaped by cool air, and then the thickness is determined. After the length reaches the specified value aft
  • 2022-08-16 What Is The Use Of Activated Carbon Filter Cotton? What is the use of activated carbon filter cotton? The activated carbon filter fabric adopts aluminum honeycomb, plastic honeycomb and paper honeycomb with through - hole structure as the carrier. Activated carbon filter cloth is made of powdered activated carbon loaded on polyurethane foam, and its carbon content is about 35 % - 50 %. It can be widely used to treat organic gases such as toluene, xylene, benzene and other benzenes, phenols, esters, alcohols, aldehydes and other organic gases and malodorous gases and various gases with low concentration and large air volume containing trace heavy metals. The exhaust gas can be directly discharged after adsorption, concentration and purification. The activated carbon adsorption filter cylinder adopts the hydraulic simulation long diameter design. And the particle size is reasonable, so that it has functions such as upper layer and lower layer adsorption, which greatly improves the purification degree of produced water and the service life of carbon. After the activated carbon adsorption filter is treated, the residual chlorine content of the water quality is relatively small, and it has outstanding performances such as odor, organic matter, colloid, iron and residual chlorine in the water body. It has a great effect on reducing the turbidity and chromaticity of the water body, purifying the water quality, and reducing the pollution to the subsequent systems (reverse osmosis, ultrafiltration, ion exchanger ). A layer of balanced surface concentration is formed on the surface of its par
  • 2022-08-15 Nonwoven Filter Material Nonwoven filter material is a kind of fiber filter material. It is based on fibers that form a network of fibers in a certain way. After a certain reinforcement treatment, a fiber filter material with certain strength and stability is formed. Nonwoven filter fabric mainly rely on the special structure of nonwovens. Compared with traditional textiles, non woven fabrics are completely separated from stretching, roving, spinning, winding, warping, sizing, weaving and other processes in the production process. It only retains the spinning process before loosening and combing. Therefore, nonwoven fabrics have the characteristics of short production process, high degree of automation, high production efficiency, low production cost and many kinds of fiber raw materials. According to the molding method, it can be divided into needle - punched filter material, spunlace filter material, spunbond filter material, melt - blown filter material and wet filter paper. Different processing methods determine that the performance of nonwoven filter materials varies greatly, especially the filtration efficiency. The perforated filter material generally refers to combing the non woven filter material into a net, and then perforating it for reinforcement. The pore size is much smaller compared to woven filter materials, but slightly larger compared to other similar nonwoven materials. In addition, it has the advantages of high por
  • 2022-08-12 Strength Properties Of Composite Filter Materials The longitudinal and transverse strengths of needle - punched composite filter materials vary greatly, which is mainly caused by the combination of needle punched non woven fabric and woven base fabric. First, depending on the processing method of the needle punched non woven, the angle of the fibers in the web after carding is basically the same. The strength of the needle punched nonwoven mainly depends on the strength of the fibers themselves and the clamping force between the fibers, which makes the needle punched non woven fabric have obvious anisotropy. When preparing the needle punched non woven fabric, the laying method is cross - laying, so that the longitudinal strength of the needle punched non woven is smaller than the transverse strength. Third, the longitudinal strength of the woven base fabric is greater than the lateral strength, while the strength of the composite filter material is mainly provided by the base fabric. It should be pointed out that during the compounding process, the damage effect to the fiber and the base fabric is particularly obvious. Therefore, from the above aspects, the longitudinal strength of the composite filter material is generally greater than the transverse strength, and the longitudinal strength and transverse strength are quite different. Therefore, in the compounding process, not only should pay attention to the compounding direction of the needle punched nonwoven and the woven base fabric, but also choose an isotropic material as much as possible. Since the strength of the composite filter material is greater than 200 N, it
  • 2022-08-11 Development Of Nonwoven Filter Materials Filter materials play an important role in daily production and life. The filtration of gases and liquids is involved in many industrial production and environmental protection devices, and the core of the filtration device is the filter medium. Textile materials as filter media can be widely used in the filtration of gases, liquids, food manufacturing and other industrial production. Filtration textiles are mainly organic woven fabrics, knitted fabrics and nonwoven fabrics. The random distribution of fibers in the nonwoven filter material makes the carrier phase flow through the fiber labyrinth of the filter material. The system can enhance the dispersion effect, so that the particle suspension phase to be separated has more opportunities to collide and adhere to the single fiber. Because the fibers of woven and knitted fabrics form regularly arranged yarns, the yarns are closely intertwined with each other, and the fibers lack the possibility of forming a labyrinthine system. Therefore, the filtration efficiency of non woven fabrics is significantly higher than that of woven fabrics and knitted fabrics, and it can also increase the flow rate of the carrier phase, that is, to speed up the filtration process. If the filter material structure adopts a density gradient, the effect is particularly significant. Due to the diversity of non woven fabric roll processing methods, a better fiber labyrinth system can be formed according to the specific use and needs of the filter material, especially the pore size and porosity of the filte
  • 2022-08-10 Overview Of PP Non Woven Fabric PP non woven fabric is nonwoven fabric made of PP through melt stretching, web laying, hot rolling bonding and other processes. It has the advantages of good air permeability, low cost and strong mechanical properties. The fiber diameter of PP non woven is usually only a few microns. Since the fibers are very fine in diameter and irregularly stacked, tangled and overlapped, it has small through holes to ensure good breathability of the nonwoven. In addition, the pore structure of non woven fabric polypropylene is fluffy. When filtering particles in the air, the fibers in the channel can fully contact the micro - nano particles in the air, thus exerting its excellent mechanical trapping effect. So as to achieve the effect of effectively filtering suspended particles in the air. It is a fiber filter material with excellent performance. In the field of air purification, polypropylene non woven material is often used as filter units for medium - efficiency filter equipment and personal protective equipment to filter small particles in the air. However, polypropylene non woven fabric rolls also have some disadvantages during use. Since the side chain of PP contains a large number of methyl groups, the presence of these methyl groups greatly reduces the chemical stability of PP and makes it easy to degrade under photothermal effects such as ultraviolet light irradiation and thermal energy. In addition, PP is a non - functional material and cannot interact with other organic substances, which also hinders its further application in the field of air purification. The study found that the surface m
  • 2022-08-09 Production Process And Influencing Factors Of Meltblown Nonwoven Fabric Meltblown nonwoven fabric is made by melting polymer masterbatch or slices in a screw extruder, forming fiber shapes by high - pressure spraying, and stretching fine short fibers by high - speed hot air. It is made by bonding each other on the mesh belt to form a fiber web. The process parameters that affect the structure and properties of melt blown nonwoven fabric include extrusion volume, cross - air temperature, mesh belt speed, take - up distance, spinneret height and gap distance. In the rough adjustment of product quality, the extrusion volume and slit width of the metering pump are the main influencing factors. In general, the smaller the extrusion volume, the smaller the slit width and the finer the fibers. Parameters such as crosswind temperature, speed of receiving mesh belt, and receiving distance of fiber mesh are the main influencing factors for fine - tuning product quality. Generally speaking, the higher the crosswind temperature, the finer the fibers; the slower the mesh belt speed, the greater the weight and thickness of the product, and the smaller the aperture of the fiber mesh, but the product feels very hard. The smaller the receiving distance, the denser the fiber network, but the fiber becomes thicker. Therefore, in actual production, the influence of various process parameters should be balanced and considered before producing qualified products. Me
  • 2022-08-08 Pore Structure And Air Permeability Of Nonwoven Filter Materials Filtration is a dynamic process of separating and capturing particulate matter dispersed in gas or liquid. The filter cloth material should have a large inner surface and appropriate pores to make it capable of capturing and adsorbing solid particles and separating them from the mixture. The pore structure of the filter material ( pore size and its distribution, porosity, etc. ) requires that it can not only block or adsorb microparticles, but also maintain a certain flux to allow the fluid to pass through smoothly. The three - dimensional network - like nonwoven fabric material composed of single fibers has become a kind of filter material with its unique multi - directional three - dimensional micro - curved channels and high porosity structure. The pore structure of non woven fabric includes pore size and its distribution, porosity. The gas permeability of a material is characterized by the volume of gas passing through a unit area per unit time. When the material porosity is comparable, its air permeability will increase with the increase of the average pore size of the material. When the average pore size of the material is comparable, air permeability increases with increasing porosity. The pore size of the material depends to some extent on the thickness of the material and the linear density of the fibers. For materials with the same fiber type and linear density, the thicker the thickness, the higher the fiber coverage, and the smaller the average pore size. And the fiber linear density, the finer the fiber, the higher the fiber coverage under the same thickness, and the smaller th
  • 2022-08-05 Study on Properties of Meltblown Nonwoven Polypropylene Nonwoven fabric has become an increasingly important filter material due to their excellent filtration performance, high yield and simple processing technology. The non woven filter cloth material has adjustable fiber fineness, messy and fluffy three - dimensional structure, high porosity, good filtration efficiency, and high production efficiency. Melt - blown method is one of the important ways to form non woven fabric in one step. At present, most of the raw materials used in the preparation of non woven fabric roll by melt - blown method are polypropylene. Polypropylene has low cost, good strength, good acid and alkali resistance, and organic solvent resistance, etc. As the melt index of PP particles increases gradually, that is, the fluidity increases. The air permeability of the product decreases gradually, that is, the air permeability decreases, and the fiber diameter gradually becomes thinner. This is due to the fact that the melt with better fluidity is more likely to be drawn and refined by hot air after passing through the spinneret hole. In addition, the addition of zirconium - based degradants helps to form a finer fibrous structure. The main reason is that the zirconium - based degrading agent breaks the partial molecular chain of polypropylene, improves the mobility of the molecular chain, and increases the melt fluidity, which makes it easier to be stretched and refined by hot air. With the increase of pump supply, the air permeability of the product gradually increases, and the

  • 2022-08-02 The Difference Between PP Non Woven Fabric And PET Non Woven Fabric PP is polypropylene raw material, namely polypropylene fiber, which belongs to thin nonwoven fabric. PET is a new polyester raw material, namely polyester fiber, without any additives in the whole production process. It is a very good environmental protection product and belongs to thick non woven fabric. Comparison of non woven fabric polypropylene and polyester non woven fabric: 1. Polypropylene non woven material is cheap and PET nonwoven fabric is expensive. The waste of PP can be returned to the furnace for reuse, and the waste of PET cannot be returned to the furnace, so the cost of PP is slightly lower. 2. The high temperature resistance of PP is about 200 degrees, while that of PET is about 290 degrees. PET is more resistant to high temperature than PP. 3. Nonwoven printing, heat transfer effect. The same width PP shrinks more, PET shrinks less, and the effect is better. PET is more economical and wasteful. 4. Tension, tension, bearing capacity, the same gram weight, PET is larger than PP tensile force, tension, bearing capacity. 65 grams of PET is equivalent to the pulling force, tension and bearing capacity of 80 grams of PP. 5. From the perspective of environmental protection, PP is doped with PP waste, and PET is all new polyester chips. PET is more environmentally friendly and hygienic than PP.
  • 2022-08-02 How To Choose The Filter Fabric Of Industrial Paper Belt Filter? How to choose the filter paper ( filter cloth ) of the industrial paper belt filter? At present, there are many filter fabric on the market. The filter cloth fabric used for industrial liquid filtration is mainly made of PET and PP materials. And if different materials or different processing conditions are used, even if the unit weight of the filter cloth material is the same, the filtration accuracy will be very different. So how should the user choose the filter fabric non woven? Consider the following aspects: 1. It is necessary to confirm the working conditions including the solid - liquid composition of the filtration object, the filtration pressure difference, the temperature of the filtration liquid, the filtration volume per unit time, the principle of the use of the filtration equipment, and the mechanical strength requirements for the filter cloth. 2. It is necessary to determine what kind of filter material is used in the current filter equipment, such as: whether there is a uniform rolling point, how much thickness, how much unit weight, and what problems are there during use ( whether there is too much foam, whether it is easy to tear, whether the flow rate Insufficient, whether the filtering precision is insufficient ) and so on. If there is no way to describe it, you can provide samples to the technician for analysis, or the technician can go to the site to investigate. 3. Determination of filtration accuracy: Filtration accuracy is a relatively accurate concept, but the pore size distribution of filter paper is a relatively random distribution. In order to determine the accuracy, it is usually mea
  • 2022-07-29 The Difference Between Electrostatic Filter Cloth And Meltblown Nonwoven Fabric Both electrostatic cotton and meltblown cloth can be used to make masks. They are all raw materials for masks, so what's the difference between them? When it comes to electrostatic filter cotton, we must first talk about electrostatic adsorption - when a tiny object with no static electricity is close to an object with static electricity, due to the phenomenon of electrostatic induction, the end close to the object with static electricity induces the opposite electrical property of the object with static electricity , and is attracted and attached to the electrostatic object. Electrostatic filter cotton is a filter cotton that adopts the principle of electrostatic adsorption. Compared with traditional mechanical filtration, electrostatic filter cotton has higher filtration efficiency and can better absorb ultra - microscopic dust. Most of the KN100 dust masks are electrostatically adsorbed filter cotton, which not only has higher filtration efficiency, but also has better resistance, making breathing easier and higher dust holding rate. Meltblown nonwoven fabric has the following characteristics: 1. The fiber web of melt blown nonwoven fabric is composed of fine shorter fibers. 2. The uniformity of the fiber web of the meltblown nonwoven is very good, and the hand feel is particularly soft. 3. The filtration performance and liquid absorption of this meltblown nonwoven polypropylene are relatively good.
  • 2022-07-28 Why Nonwoven Fabric Is A New Generation Of Environmentally Friendly Material A nonwoven fabric is a fabric that does not require weaving, but spun short fibers or filaments for directional or random support, forming a fibrous network structure, which is then made using methods such as mechanical, thermal bonding, or chemical reinforcement. Non woven fabric roll is a new generation of environmentally friendly materials, with the characteristics of waterproof, breathable, flexible, non-flammable, non - toxic and non - irritating, and rich in color. When burning, it is non - toxic, odorless, and has no residual substances. Nonwoven fabric does not pollute the environment. Therefore, environmental protection comes from this. The chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, so it can degrade effectively and enter the next environmental cycle in a non - toxic form. As an environmentally friendly product, non woven fabric is mainly used in nonwoven handbags. Because we all know that before and now, most of the shopping bags are mainly plastic bags. Plastic bags are not easy to degrade, even if they are buried in the soil, they will not degrade for a long time. The non woven fabric washable tote bag only needs three more months in the outdoor soil. The important thing is that the non woven fabric tote bag can be recycled six to seven times, which greatly reduces the consumption of shopping bags, so it is an environmentally friendly product.

  • 2022-07-26 What Are The Common Quality Problems Of Nonwoven Fabric? What are the common nonwoven fabric quality problems? Quality management is an important part of the production and processing links of non woven fabric enterprises, and its important role is well known. However, in the actual production process, the quality of non woven fabric roll products is often difficult to control, resulting in various quality problems of nonwoven fabric. 1. Cut corners. For example, if a customer places an order for 80g of fabric per square meter, these small businesses will use 70g of fabric per square in order to reduce costs. If the customer does not have special equipment for testing, it is generally impossible to find it. 2. Insufficient gram weight. The weight of the nonwoven fabric can directly affect the weight of the customer's product. During the laying process, the layers are uneven and cannot be accurately connected at the two ends. 3. Uneven thickness. The uneven thickness of non woven filter fabric is also caused by the uneven distribution of fiber cotton during carding, web laying, and lack of technical experience. 4. The

Polyester fiber: close to the flame: melt; contact the flame: melt, smoke, burn slowly; leave the flame: continue to burn, sometimes extinguished
  • 2022-07-21 What Is The Material Composition Of Nonwoven Fabric? What is the material composition of nonwoven fabrics? Nonwoven products are different from general textiles in terms of material composition. In order to improve the air permeability and flexibility of nonwoven fabrics and improve the stretchability and quality of non woven fabric roll, non woven fabrics are very different from ordinary textiles in terms of material composition. Non woven fabrics mostly use polypropylene ( pp material ) pellets as raw materials. It is produced by continuous one - step method of high temperature melting, spinning, laying, hot pressing and coiling. The top three fibers used in nonwoven production are polypropylene ( 62 % of the total ), polyester ( 24 % of the total ) and viscose ( 8 % of the total ). Between 1970 and 1985, viscose fibers were used in many nonwoven fabrics. The fibers used in the production of nonwoven fabrics are mainly polypropylene ( PP ) and polyester ( PET ). In addition, there are nylon ( PA ), viscose, acrylic, ethylene ( HDPE ), and vinyl ( PVC ). According to the application requirements, nonwoven fabrics are divided into two categories: disposable application type and durable type. To sum up, there are many materials for processing and making nonwoven fabrics, and the materials are mainly polyester, polypropylene, aramid, acrylic, nylon, composite, ES, 6080, vinylon, spandex and so on. Nonwoven fabrics produced by different materials and different processes have great differences in sales prices.
  • 2022-07-20 The Role Of Filter Cotton We all know that the air contains a lot of dust and particles. Because the weight of these dust particles is very light, when the flowing air acts on these dust particles, it will offset the weight of the dust particles themselves, so that these dusts are in a floating state. Only in a relatively closed space, the air is relatively static. The dust will fall to the ground under the action of the earth's gravity, which is why a thick layer of dust will be seen on the furniture and the ground after a period of time in a room with closed doors and windows when no one is inhabited. The amount of dust in the air is related to objective factors, such as weather conditions, seasonal changes, industrial production, mining, land desertification, soil erosion, environmental pollution, etc. At the same time, dust has an impact on the human body, on production, on product quality, on the environment, on the beauty of natural scenery, and on ecological balance. Therefore, filter cotton is very important to us. In industrial production, the dust in the air falls on the parts of the machine, which will speed up the wear of some parts and reduce the working life of the machine. Dust permeates the workshop, reducing visibility, hindering personnel operations, reducing labor productivity, and sometimes even causing accidents. Therefore, filter cotton has an indispensable position. Many industrial productions must be carried out in relatively clean spaces, such as biopharmaceuticals, food production, air cooling, etc. These environments must have flowing air. However, there can be no dust. At this time, it is necessary to filter the dust with filter cotton to meet the demand environment for production and operation.

The first is the use of nonwoven fabric environmental protection bags. The service life of nonwoven bags is longer than that of plastic bags. Non woven fabric is recyclable, inexpensive, and easy to promote. Nowadays, most people go to supermarkets and shopping malls to use environmental protection bags, which reduces the use of plastic bags and better protects the environment. Because environmental protection bags are a little more expensive than plastic bags, all many businesses print advertisements on " environmental bags ". Advertising fees can offset usage costs. Secondly, non woven fabric roll has become an indispensable material in hygiene products. Non woven fabric washable has become the first choice for hygiene materials because of their good air permeability and strong filtering ability. Filter cloth material has also become the best choice for plastic agricultural film substitutes in agriculture and vegetable cultivation. The air permeability of nonwoven fabrics is better than that of agricultural films. This not only increases the temperature in the shed at night, but also reduces the temperature in the shed at no
