Eighteen methods to identify non-woven materials

There are many kinds of non-woven materials, and it is difficult to distinguish them without careful identification. Let's take a look at the 13 methods to distinguish the types of non-woven materials by hand feeling. 1. Vinylon fiber: cross-sectional shape: round waist, skin-core structure; longitudinal shape: 1 to 2 grooves. 2. Polyester, nylon, and polypropylene fibers: Cross-sectional shape: round or special-shaped; longitudinal shape: smooth. 3. Spandex fiber: The surface is dark and deep, showing unclear bone-shaped stripes, cross-sectional shape: irregular shape, round, potato-shaped; longitudinal shape 4. Chlorine fiber: cross-sectional shape: close to circular; longitudinal Morphology: smooth surface 5. Acrylic fiber: cross-sectional shape: round, dumbbell or leaf shape; longitudinal shape: smooth or striped surface. 6. Acetate fiber: cross-sectional shape: trilobal or irregular zigzag; longitudinal shape: longitudinal stripes on the surface. 7. Rich and strong fiber: Cross-sectional shape: less tooth shape, or round, oval; longitudinal shape: smooth surface. 8. Ordinary viscose fiber: Cross-sectional shape: zigzag, skin-core structure; longitudinal shape: longitudinal grooves. Nine. Mulberry silk fiber: Cross-sectional shape: irregular triangle; longitudinal shape: smooth and straight, longitudinal stripes. 10. Rabbit hair fiber: Cross-sectional shape: dumbbell-shaped, with hairy pith; longitudinal profile: scales on the surface 11. Wool fiber: Cross-sectional shape: round or approximately round, some with hairy pith; longitudinal shape: There are scales on the surface. 12. Hemp (ramie, flax, jute) fiber: Cross-sectional shape: round or polygonal waist, with a middle cavity; longitudinal shape: horizontal nodes, vertical lines. 13. Cotton fiber Cross-sectional shape: round waist with middle waist; longitudinal shape: flat ribbon shape with natural twist. 14. Touch Method One Spandex yarn has very large elasticity, and its length can be stretched to more than five times at room temperature. 15. Touch Method Two Among the chemical fibers, only viscose fibers have a large difference in strength between the dry and wet states. 16. Touching method three Silk is long and slender, with special luster. 17. Touch method 4 Wool fiber is curly and elastic. 18. Touching method 5 The hemp fiber feels rough and hard.
