Unveil the mystery of polyester low-elastic silk
Nylon is the first synthetic fiber in the world. The nylon chain has -CO-, -NH- groups in the molecule, which can form hydrogen bonds in the molecule or in the molecule, or can be combined with other molecules, so the nylon absorbs moisture. Good ability and ability to form a better crystalline structure. Polyester low-elastic yarn is a kind of textured yarn of nylon chemical fiber. It is made of polyester (PET) as raw material, high-speed spinning polyester pre-oriented yarn (POY), and then processed by drawing false twisting. It has the characteristics of short process, high efficiency and good quality.
Polyester low-elastic yarn has the characteristics of high breaking strength and elastic modulus, excellent heat setting, good resilience, heat resistance, light resistance, corrosion resistance, easy washing and quick drying. High characteristics, good heat insulation, comfortable hand, soft gloss and so on. Polyester low-elastic yarn is an ideal material for knitting (weft knitting, warp knitting) or woven processing. It is suitable for making fabrics (such as suits and shirts), bedding (such as quilts, bedspreads, mosquito nets) and decorative items (such as curtain fabrics). , sofa cloth, wall coverings, car interior fabrics, etc.
The low-elastic yarn also has a sewing effect, and the copying edge is also called a seaming. This process is required for all pieces of clothing. Since the main purpose of the copying is to prevent the yarn of the piece from being scattered, the strong requirement for the edge line is not high. In order to save costs, the edge line is generally made of polyester mesh wire, which is not twisted and has a lower strength than the sewing thread. It differs from the general sewing thread in that the quilting line is made of polyester filament without twisting, and the sewing thread is made of polyester staple fiber and twisted.
