According to the name of the non woven fabric, its manufacturing process is different. The following describes the production process of some non woven fabrics. 1. Spunlace nonwoven fabric: The high - pressure micro - water jet is sprayed into one or more layers of fiber webs to entangle the fibers together. The fiber web is strengthened and has a certain strength. 2. Heat - sealing non woven fabrics: refers to adding fibrous or powdery hot - melt adhesive reinforcement materials to the fiber web, and then heating, melting and cooling to reinforce the fiber web into cloth. 3. Pulp air - laid nonwoven fabric: also known as dust - free paper and dry - laid nonwoven fabric. The utility model uses air - flow weaving technology to loosen the wood pulp fiberboard into a single fiber state. The fibers are then adhered to the mesh curtain by the air method, and the fiber web is consolidated into a cloth. 4. Wet - laid nonwoven fabrics: The fiber raw materials placed in the water medium are loosened into single fibers, and different fiber raw materials are mixed at the same time to make fiber suspension pulp. The suspension slurry is transported to the netting tissue, where the fibers net in a wet state and then consolidate into a cloth. 5. Spunbond non woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are spread into a mesh. The web is self - bonded, thermally bonded, chemically bonded or mechanically reinforced.
  • 2022-05-30 The Difference Between Nonwoven Fabrics And Ordinary Fabric Textile fibers include natural fibers such as cotton, hemp, wool, and silk, as well as chemical fibers such as viscose, polyester, spandex, nylon, and acrylic. From fiber to fabric, it generally goes through two steps: one is that the fiber is formed into a yarn through the spinning process, and the other is that the yarn is formed into a fabric through the weaving process. For example, woven and knitted fabrics commonly used in apparel are formed through spinning and weaving processes. Woven fabrics ( woven fabrics ) are made of two sets of mutually perpendicular yarns staggered horizontally and vertically on the loom according to certain rules, with stable structure and flat surface. Knitted fabric is formed by one or more groups of yarns strung into a circle on a knitting machine according to a certain rule. It has a soft texture, good ductility and elasticity. What is the raw material of non woven fabric? As PetroChina and Sinopec began to build mask production lines to produce and sell masks, we gradually realized that masks are inextricably linked to oil. Propylene can be obtained by petroleum distillation and cracking, and polypropylene can be obtained by polymerization. Polypropylene can be further made into polypropylene fibers, which is what we usually call polypropylene fibers. Polypropylene fiber ( polypropylene fiber ) is the main fiber raw material for the production of non-woven fabrics, but it is not the only raw material. Polyester fibers ( polyester ), polyamide fibers (

In addition to carbon, the main components of activated carbon also contain elements such as oxygen and hydrogen. Because of the irregular arrangement of microcrystalline carbon in the structure of activated carbon, there are pores between cross-connections, and carbon structure defects will be generated during activation. Therefore, it is a kind of porous carbon with low bulk density and large specific surface area. 2. Principle of activated carbon water purification Activated carbon is a very fine carbon particle with a large surface area, and there are even finer pores in the carbon particles - capillaries. This kind of capillary has strong adsorption capacity, and because of the large surface area of carbon particles, it can fully contact with impurities. These impurities are adsorbed by the capillary and have a purification effect. 3. Requirements for activated carbon The activated carbon used in a good water purifier must have the characteristics of large adsorption capacity, long service life, high mechanical strength, low ash content, easy flushing, and good water quality. It can not only remove odor and improve chroma, but also has a high removal rate for various toxic and
