Characteristics and distinguishing methods of non-woven products

How can I tell from the clothes or fabrics bought on Taobao or physical stores what kind of material it is made of? Today, the author will discuss specifically how to distinguish non-woven products from other fabrics. It is easy for people to confuse non-woven fabrics with dust-free fabrics. Non-woven fabrics, also known as non-woven fabrics, are a new generation of materials that are water-repellent, breathable, flexible, non-combustible, non-irritating, and rich in colors. If the non-woven fabric is naturally decomposed outside, its long life is only 90 days, and it will decompose within 5 years when placed indoors. There will be no leftover substances when burned, so it does not pollute the environment and is suitable for washing. It directly uses polymer chips, short fibers or filaments to form new fiber products with soft, air-permeable and planar structure through various web forming methods and consolidation technologies. It has properties that plastic products do not have, and its natural degradation time is much shorter than that of plastic bags. Therefore, non-woven bags made of non-woven fabrics are also recognized as economical shopping bags. The dust-free cloth is double woven of polyester fiber, the surface is soft, it is easy to wipe the sensitive surface, the friction does not detach the fiber, and it has good water absorption and cleaning efficiency. The cleaning and packaging of products are completed in the ultra-clean workshop. The optional edge banding of dust-free cloth generally includes: cold cutting, laser edge banding, and ultrasonic edge banding. Microfiber dust-free cloths are generally perfectly sealed with laser and ultrasonic waves; dust-free cloths, dust-free wiping cloths, ultra-fine fiber dust-free cloths, and microfiber wiping cloths are made of continuous polyester fiber double-woven fabric with soft surface and can be used for wiping Sensitive surface, low dust production and non-fiber off by friction, with good water absorption and cleaning efficiency. Especially suitable for dust-free purification workshop. The edges of dust-free cloth, dust-free wiping cloth, microfiber dust-free cloth, and microfiber wiping cloth are sealed by an advanced trimming machine. After wiping, there will be no particles and thread ends, and the ability to remove dirt is strong. 1. Hand visual inspection method: This method is suitable for non-woven materials in loose fiber state. (1) Cotton fiber is shorter and thinner than ramie fiber and other hemp fiber and wool fiber, often with various impurities and defects. (2) Hemp fiber feels rough and hard. (3) The wool fiber is curly and elastic. (4) Silk is long and slender, with special luster. (5) Among chemical fibers, only viscose fiber has a large difference in strength between dry and wet states. (6) Spandex yarn has very large elasticity, and its length can be stretched to more than five times at room temperature. 2. Microscopic observation method: It is to identify the non-woven fabric fiber according to the longitudinal and cross-sectional morphological characteristics of the fiber. (1) Cotton fiber: cross-sectional shape: round waist with middle waist; longitudinal shape: flat ribbon shape with natural twist. (2) Hemp (ramie, flax, jute) fibers: cross-sectional shape: round or polygonal waist, with a middle cavity; longitudinal shape: horizontal nodes, vertical lines. (3) Wool fiber: cross-sectional shape: round or approximately round, some with pith; longitudinal shape: scales on the surface. (4) Rabbit hair fiber: cross-sectional shape: dumbbell-shaped, with hair pulp; longitudinal shape: scales on the surface. (5) Mulberry silk fiber: cross-sectional shape: irregular triangle; longitudinal shape: smooth and straight with stripes longitudinally. (6) Ordinary viscose fiber: cross-sectional shape: zigzag, skin-core structure; longitudinal shape: longitudinal grooves. (7) Rich and strong fiber: cross-sectional shape: less tooth shape, or round, oval; longitudinal shape: smooth surface. (8) Acetate fiber: cross-sectional shape: trilobal or irregular zigzag shape; longitudinal shape: longitudinal stripes on the surface. (9) Acrylic fiber: cross-sectional shape: round, dumbbell or leaf shape; longitudinal shape: smooth or striped surface. (10) Chlorine fiber: cross-sectional shape: close to circular; longitudinal shape: smooth surface. (11) Spandex fiber: cross-sectional shape: irregular shape, round, potato-shaped; longitudinal shape: dark and deep surface, showing unclear bone-shaped stripes. (12) Polyester, nylon, and polypropylene fibers: cross-sectional shape: round or special shape; longitudinal shape: smooth. (13) Vinylon fiber: cross-sectional shape: round waist, skin-core structure; longitudinal shape: 1 to 2 grooves. The company has always adhered to the principle of honesty, taking the research and development and manufacturing of high-quality and novel building materials as its responsibility, and constantly improving the quality of non-woven products at reasonable prices; professional and fast pre-sales and after-sales services; for the owner And dealers provide quality services.
