  • 2023-04-18 Is The Meltblown Nonwoven Fabric As Thick As Possible? The increase in the thickness of the non woven fabric represents an increase in the net weight per unit area, and the corresponding compressive strength will increase. However, due to its own structure type, the increase in thickness does not equal the increase in the barrier properties of microbial strains. For example, if a piece of thickened nonwoven fabric is used, the increase in the weight of the spunbond layer cannot reasonably improve its antibacterial properties. Only when the diameter of the important filter layer ( the meltblown nonwoven fabric layer ) can effectively filter microbial bacteria and dust intrusion , its antibacterial properties meet the requirements. As the thickness increases, the air permeability of its packaging products will also be affected. Melt blown nonwoven fabric: important factors affecting the price of non woven fabric roll. 1. The price of crude oil in the raw material / crude oil market Because non woven fabrics belong to chemical raw materials, the raw material is PP, and polypropylene is also made of pe, a petroleum refining product, so changes in the price of propylene will directly affect the price of nonwoven fabrics. 2. Equipment and technical capital investment of the manufacturer The quality of imported products is different from that of domestic equipment, or the raw materials are the same due to different production processes. The tensile strength, surface treatment technology, uniformity and touch of non woven fabrics are different, which will also affect the price of non woven fabrics. 3. Total
  • 2023-04-17 Techniques For Controlling The Handfeel Of Needle Punched Non Woven Fabric The hand feeling requirements of needle punched non woven fabric are generally comfortable and skin - friendly, and the quality of such fabrics is generally better. However, in some industries, the hand feel of the fabric should not be too soft, but should be slightly harder. Therefore, manufacturers are required to moderately control the feel of the cloth: 1. Because the needle punched non woven is also produced from polypropylene, it will be brittle if it is too hard, the tensile force is very bad, and it is prone to breakage. While controlling the feel, it also has the strength problem of non woven fabrics. 2. The soft material feels very soft and close to the real knitted fabric. The needle punched nonwoven has good toughness, strong tensile strength and is not easy to tear, because the fabric will feel weaker when it is soft. Hard material is the way manufacturers often do. 3. After needle punched non woven, is made hard, the fabric of the same weight feels much thicker than the material, so most manufacturers like to make hard material. Although the feel of needle punched non woven fabric can reflect its quality. However, the extent to which the feel of the cloth can be controlled depends on various applications. Considering the strength of the cloth, if the cloth is too soft, it will break easily.

Of course, the first thing to bear the brunt is the use of non woven fabric roll environmental protection bags. Non woven fabric washable bags have a longer service life than plastic bags and can be recycled. It is cheap, easy to promote and so on. Now when people go shopping in supermarkets and shopping malls, most of them use green bags, which reduces the use of plastic bags and better protects the environment. Because green bags are more expensive than plastic bags, many businesses print advertisements on " green bags ". Advertising fees may offset usage costs. Secondly, nonwoven fabrics have become an indispensable material in sanitary products. Non woven fabrics have become the first choice for sanitary materials because of their good air permeability and strong filtering ability. Nonwoven fabrics have also become the best choice for plastic agricultural film substitutes in agriculture and vegetable cultivation. Non woven fabrics have good air permeability and are thicker than agricultural films, which is suitable for agricultural vegetable cultivation.

The temperature difference between day and night in the shed is reduced, and there is no need to remove the film to harden
  • 2023-04-04 ES Non Woven Fabric Hot rolling is a web - forming technology in the production process of non woven fabric, and it is a process of forming fabrics after cooling and laying silk. Hot rolling has high heat ( 100 ~ 150 degrees ). The rolling wheel rolls over the uniform fiber filaments to melt and form a web, so there will be rolling spots on the surface of the ES hot air cotton fabric. It resembles a pinhole, but does not penetrate, depending on the size and density of the roll barbs. As a process, hot - rolled non woven fabric roll is not a specific kind of cloth, but a general term for a class of nonwoven fabric made through similar processes. 1. Lightweight: Polypropylene resin is used as the main raw material for production, and its specific gravity is only 0.9, which is only three - fifths of that of cotton. It is fluffy and feels good. 2.

  • 2023-03-31 What Are The Three Construction Methods Of Needle Punched Non Woven? There are three construction methods of needle punched non woven, full sticking, empty laying and mechanical fixation. Then, the polypropylene polymer composite waterproof membrane is fully glued. Before the construction of needle punched nonwoven, it is necessary to lay the coiled material on the surface of the bottom layer without bonding it first. Pay attention to straight and flat when laying, and the material cannot be twisted, and then cut it off. Halve the long sides of multiple needle punched nonwoven, and apply glue to the folds of the bottom layer and the outer surface of the coil respectively. When the adhesive is dry and not sticky to the hands, attach the pre - paved waterproof membrane surface and press it tightly. Fold the unfolded part, continue to compact according to the above method, and then weld the seam. The special parts of needle punched non woven fabric are used as waterproof membrane construction, and additional layers are made accordingly. The main purpose of needle punched non woven can be used in some daily life, such as home decoration can be used as wall coverings, tablecloths, bedcloths, bedspreads, etc. It can also be used in the planning and production of clothing, as part of the inner lining, fusible interlining, wadding, shaped cotton, various synthetic leather base fabrics, etc. It can also be used as some daily necessities, including towels, wet wipes, cotton pads, sanitary napkins, and some disposable hygiene products.

  • 2023-03-30 What Is The Process Of Hot Air Through Nonwoven Fabric? Air-through nonwoven ES fiber is one of the ideal thermal bonding fibers, mainly used for thermal bonding processing of non woven fabric. When the combed fiber web is thermally bonded by overheating rolling or hot air passing, the low melting point component forms a fusion bond at the intersection of fibers. After cooling, the fibers at the non - intersections remain in their original state, which is a form of " point bonding " rather than " area bonding ", so the product has the characteristics of fluffy, soft, high strength, oil absorption, and blood absorption. In recent years, the application of thermal bonding methods has been rapidly developed, fully relying on these new synthetic fiber materials. After the hot air non woven fabric ES fiber and PP fiber are mixed, they are thermally bonded or needle - punched to make the ES fiber cross - linked and bonded to each other. The advantage of this method is that it does not require the use of adhesives and backing. In hot air bonding, air is the heat carrier. As the air penetrates the web, heat is transferred to the fibers. Therefore, first of all, it is necessary to ensure that the hot air will not damage the structure of the fiber web during the circulation process. In the initial stage of the fiber web entering the drying chamber, the fibers are only dependent on the holding force. If the introduction method and speed of the hot air flow are not suitable, the structure of the fiber web will be damaged. Secondly, it is necessary to ensure that the fiber web is e
  • 2023-03-30 The Main Factors Affecting The Performance Of Hot Air Cotton In the hot air bonding process of hot air cotton, the heat carrier is hot air. As the hot air penetrates the web, heat is transferred to the fibers, melting and creating bonds. Therefore, the temperature, pressure, fiber heating time and cooling speed of the hot air will directly affect the performance and quality of the product. As the temperature of the hot air increases, the vertical and horizontal strength of the product increases, but the softness of hot air through nonwoven fabric decreases and the hand feels hard. The strength and softness are shown as a function of temperature for the production of 16 G / M product. Hot air pressure is an important parameter affecting hot air bonding products. Generally speaking, as the number and thickness of the hot air cotton fabric fiber web increase, the pressure should increase accordingly so that the hot air can pass through the fiber web smoothly. However, before the fiber web is bonded, excessive pressure will destroy its original structure and cause the fiber web to be uneven.
  • 2023-03-28 Matters Needing Attention When Replacing Filter Cotton The filter cotton we generally refer to refers to the air filter cotton. According to the different materials, the air filter cotton is also divided into four types: synthetic fiber filter cotton, non woven fabric filter cotton, activated carbon filter cotton and glass fiber filter cotton. What about the problems that need to be paid attention to when replacing the filter cotton? If you can accurately determine the average cleaning and replacement cycle for the air filters you purchase, you can make a rough judgment call. Start by making an approximate air filter cleaning and replacement schedule, knowing when it will filter at an approximate time. Check the efficiency and filtering effect. Considering the actual situation of the production site, of course, when determining the cleaning and replacement cycle of the air filter cotton, it is also necessary to understand the impact of the filtering work on the environment, which will directly affect the service life of the air. When replacing, be sure to follow the corresponding steps to replace the filter cotton, and pay attention to the quality of the replaced filter cotton. Of course, if the quality of the original filter cotton is not so good, you can actually take this opportunity to replace the air filter material. When replacing, directly replace with new filter cotton, and after using it for a period of time, you can compare the use effect of the two filter cottons. If the old one is satisfactory, you can replace it with the original one when you replace the filter cotton
  • 2023-03-24 Indispensable Hot Air Cotton For N95 Masks Melt blown nonwoven and hot air cotton are both raw materials of N95 masks, so what is the difference between them? The hot air through nonwoven fabric, which is also called filter cotton, can only achieve the initial filter effect, so it cannot replace the melt blown nonwoven fabric. Since hot air non woven fabric cannot replace melt blown nonwoven, what role does it play in KN95 masks? Is it an indispensable material? The hot air cotton fabric is a kind of filling material in the KN95 mask, which takes into account the effect of warmth retention and protection. The middle of the folded mask mainly plays the role of thermal insulation, moisture - proof and moisture - proof, and improves the comfort of the wearer. Although hot air cotton fabric cannot replace meltblown nonwoven fabric, both are N95 mask materials, and both are indispensable. Hot air cotton ( non - glued cotton ) is a new type of thermal insulation material, which is a replacement product of spray - glued cotton and imitation silk cotton. Its fixation method is to mix a certain amount of low - melting fiber or two - component fiber in the raw material. After heat drying in the production process, the fibers are fused immediately, so the production speed of hot air cotton is fast, the output is high, and the cost is low. Hot air cotton can be used in various fields according to the density. The general thickness is used for KN95 protective masks, baby diapers, a
  • 2023-03-06 About Hot Air Cotton What is hot air cotton? Hot air cotton ( non - glued cotton ) is a new type of thermal insulation material, and it is a replacement product of spray - glued cotton and imitation silk cotton. ES hot air cotton is different from spray cotton. Its fixation method is not to use latex but to mix a certain amount of low - melting fiber or two - component fiber in the raw material. After heat drying in the production process, the fibers are fused together. Therefore, the production speed of hot air cotton non woven is fast, the output is large, and the cost is low. The " ES " in ES hot air cotton is a composite fiber, which is the abbreviation of " Ethylene - Propylene Side By Side " in English, and refers to the name of the raw material. As a new type of heat - bonding composite fiber, ES fiber has won high praise in the world. Among them, the " hot air " of ES hot air cotton refers to a process. After the fibers are carded, the hot air on the drying equipment is used to penetrate the fiber web, so that it is heated and bonded to form a nonwoven fabric.
  • 2023-03-03 Why Water Electret Jet Meltblown Nonwoven Fabric Stands Out Today? At present, meltblown nonwoven fabric is widely used in the field of air filter materials. Since the 1970s, various charging technologies and charging technologies by mixing different fibers have been developed and utilized. As a result, there are various electrostatic column - pole processes, such as electrospinning, corona charging, friction electrification, thermal polarization, low - energy electron beam bombardment, pure water jetting, etc. Due to the different electrostatic electret processes of the materials, the properties of the formed electrets are also quite different, and there are differences in the improvement of filtration performance and the persistence of static electricity. As we all know, with the increase of storage time, the electrostatic potential of the melt blown nonwoven fabric on the surface of the electret material attenuates. It tends to be stable in a few days or so. This shows that polypropylene meltblown nonwoven fabric has good electrostatic properties. The greater the charging voltage, the greater the electric field strength, and the greater the electrostatic potential on the surface of the material. But it cannot exceed a certain limit. If the charging voltage exceeds 10Kv, spark discharge will occur, thus causing the material to be broken down. Therefore, the charging voltage should be chosen carefully. At present, in terms of the properties of electrostatic electrets, the corona discharge method is a better electr

  • 2023-02-28 Introduction Of Filter Cotton Process Introduction of filter cotton process:cotton blending - opening - secondary opening - mixing box - carding - laying - hot air setting - cooling - cutting and curling. 1. Cotton blending: According to the different requirements of customers, the filter cloth material cotton is mixed according to different proportions. After weighing the initial weight, it is poured into the mixer and stirred by the machine. The purpose is to mix all kinds of raw materials evenly. 2. Opening: transfer the agglomerated fibers evenly spread to the licker - in roller device through rollers, and send them in sequence. After the fiber clusters are powerfully opened, they are sent to the secondary feeding device by the fan. After the second delivery, the fiber cluster is sent to the cotton mixing box by the fan, and mixed by the vibration of the wool hopper. 3. Carding: The cotton layer with uniform thickness and distribution is sent to the upper screen by the cylinder and doffer carding lathes, and then spread into a net by the shaking screen. 4. Laying the net: Swing back and forth by the shaking screen, laying a uniform net layer and then sending it into the oven by the bottom screen. 5. Hot air setting: send the uniform cotton layer into the oven, and the low - melting - point fibers in the oven at a certain temperature will entangle various fibers to form synthetic fiber cotton. 6. Cold air shaping, edge trimming and curling: After the air filter material synthetic fiber cotton is shaped by cold air, the thickness is determined by the fin

  • 2023-02-23 Popular Science About Flame - retardant Non Woven Fabric Flame - retardant non woven fabric is a kind of fabric formed without spinning and weaving. Polyester flame - retardant non woven fabric is a kind of flame - retardant non woven fabric. Its main component is polyester. Viscose fiber belongs to chemical fiber and is the polymerization product of terephthalic acid or diethyl terephthalate and ethylene glycol. The characteristics are as follows: high strength, good elasticity, good heat resistance, smooth surface, good wear resistance, good light resistance, corrosion resistance, and poor dyeability. Its flame retardant mechanism is mainly to add flame retardants. Flame retardant is an additive for materials, generally used in polyester plastics, textiles, etc. Adding it to polyester achieves the purpose of flame retardancy by increasing the ignition point of the material or hindering the combustion of the material, thereby improving the fire safety of the material. Flame retardant finishing non woven fabric: flame retardant finishing is to fix the flame retardant on the conventional nonwoven fabric through adsorption deposition, chemical bonding, non - polar Van Der Waals Force bonding and adhesion, etc. to obtain the flame retardant effect. Compared with fiber modification, this method has a simpler process and less investment, but the washing performance is poor, and it has a certain impact on the appearance and feel of the non woven fabric roll. Flame retardant finishing can be carried out by dipping method and spraying method. Flame retardant nonwoven filte
  • 2023-02-21 A Closer Look At Nonwoven Fabrics You may always hear non woven fabrics in your life, what exactly are nonwoven fabrics, let us find out together. Non woven fabrics are not interwoven and knitted together by one yarn, but the fibers are directly bonded together by physical or chemical methods. Therefore, when you get the sticky scale in your clothes, you will find that you can't pull out the thread ends one by one. Non woven fabric has no warp and weft, which is very convenient for cutting and sewing. And the filter cloth material is light and easy to shape. Nonwovens have broken through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide application, and multiple sources of raw materials. Nonwoven fabrics are less strong and durable than woven fabrics and cannot be washed like other fabrics. Because the fibers are arranged in a certain direction, it is easy to split from the right angle direction and so on. Therefore, the improvement of the production method is mainly focused on the improvement of preventing splitting. Non woven filter fabrics remain a constant in the building and construction market. Although you don't usually see them, nonwovens play a huge role in new construction and renovations of existing buildings and homes. They are part of house wrappings, roofing materials, window flashing, thermal and acoustic insulation, and many other areas. Manufacturers of non woven materials and composites a

Now let's understand the classification of air filter cotton and the selection of air filter cotton. According to the efficiency, the air filter cotton is divided into two types: primary filter cotton and medium - effect filter cotton. According to different materials, the air filter media can be divided into four types: synthetic fiber filter cotton, nonwoven filter cotton, glass fiber filter cotton, and activated carbon filter cotton. Everyone knows that the air contains a lot of dust particles, and the function of air filter cotton is mainly to filter the dust particles in the air. According to European standards, air filter cotton can be divided into: G1, G2, G3, G4, F5, F6, F7, F8. Primary ( coarse ) filter cotton mainly filters dust particles larger than 5 μm, and is generally used at the suction inlet of ventilation equipment and air control system as a pre - filter or coarse filter where it is directly in contact with outdoor air. The air filter cloth material is also used as a filter material for filter materials such as plate filters, folded plate filters, and bag filters. Medium - efficiency filter cotton mainly filters dust particles larger than 1 μm. It is generally used for secondary filtration after coarse - efficiency filtration, and is also mostly used
