Description
Technical Field

Background
Oldham yarns, also known as Kegen yarns, also known as Oldham yarns, and Oldham yarns. The English name is: organza. The light yarn with transparent or semitransparent texture is mostly covered on satin cloth or Silk (Silk). The wedding dress designed by the French man is mainly made of European-root dress.
Nylon is a trade name for polyamide fiber, also known as Nylon (Nylon). The basic component of Polyamide (abbreviated as PA) is aliphatic Polyamide linked by amide bonds [ NHCO ] -. The polyamide is mainly used for synthetic fibers, has the most outstanding advantages that the wear resistance is higher than that of all other fibers, is 10 times higher than that of cotton and 20 times higher than that of wool, and the wear resistance can be greatly improved by slightly adding some polyamide fibers into the blended fabric; when the stretch is extended to 3-6%, the elastic recovery rate can reach 100%; can withstand ten thousand times of bending without breaking.
The strength of the polyamide fiber is 1-2 times higher than that of cotton, 4-5 times higher than that of wool, and 3 times higher than that of viscose fiber. However, polyamide fibers have poor heat resistance and light resistance and poor retention properties, and the resulting garments are not as stiff as polyester. In addition, both of nylon-66 and nylon-6 used for clothing have the disadvantage of poor hygroscopicity and dyeability, and therefore, new polyamide fibers of nylon-3 and nylon-4, which are new varieties of polyamide fibers, have been developed, and are characterized by light weight, excellent crease resistance, good air permeability, good durability, dyeability, heat setting and the like, and thus are considered to have a great development prospect.
However, the dyeing and color fixing performances of the traditional nylon fiber as a summer fashion fabric are still to be improved, so that a preparation method of the ultraviolet-resistant nylon fiber easy to dye is needed to be researched.
