Q: What is the Raw material of Double covered yarn?

A: Covered yarn, also known as wrapped yarn, is a kind of yarn of new structure. It takes filament or staple fiber as the core and outsources another kind of winding and coated yarn strip in a certain way, which can also be filament or staple fiber. The outer yarn covers the core yarn in a spiral manner. It is characterized by uniform dry, plump, smooth yarn with less hair, high strength and less broken end. Coated yarn is generally used for spinning women's underwear, maternity pants, pantyhose, bathing suit and tights and other clothing products with close contact with the human body, the basic requirements for its uniform dry, fluffy and plump, high strength, less broken head, etc.
3. Rubber string is very easy to see in daily life, it is often used for elastic socks, gloves, wrist guards, masks and hair accessories. Currently, rubber string on the market are imported A-grade rubber string wrapped with double strands of polyester or nylon silk. The polyester silk or nylon silk used has large elasticity and high strength. The production of covered yarn with rubber string as the core yarn can broaden the application range of covered yarn.

In addition to its special structure, core-spun yarn has many advantages. It can take advantage of the excellent physical properties of the core-spun chemical fiber filament and the properties and surface characteristics of the outsourced staple fiber to give full play to the strengths of the two fibers and make up for their shortcomings. For example, polyester cotton core-wrapped yarn can give full play to the advantages of polyester filament crisp, anti-crepe, easy to wash and quick to dry, and at the same time can play the advantages of outsourcing cotton fiber good moisture absorption, less static electricity, not easy to pilling. The woven fabric is easy to dye and finish, comfortable to wear, easy to wash, and bright color, beautiful and generous. Core-cored yarn can also reduce the weight of fabric while maintaining and improving the performance of fabric, and take advantage of the different chemical properties of chemical fiber filament and outsourcing fiber. In the dyeing and finishing process of fabric, chemicals can be used to decompose part of outsourcing fiber and make the three-dimensional pattern effect of rotting fabric.
Core-spun yarn is generally made of synthetic fiber filament with good strength and elasticity, and spun with cotton, wool, viscose fiber and other short fibers. Core-spun yarn has the excellent properties of filament yarn and staple fiber. The common core-covering yarn is terylene cotton core-covering yarn, which takes polyester filament as the core yarn and outsources cotton fiber. There is also spandex core-spun yarn, which is made of spandex filament yarn and other fibers. Knitted fabrics or jeans made from this core-spun yarn can stretch and fit comfortably.

The reason why spandex has high elasticity and good resilience is determined by its polymer block copolymer structure. In the block copolymer structure, the soft chain segment is composed of low molecular weight polyester or polyether chain, which can easily be deformed, so that the fiber is easy to be elongated and deformed, with greater elongation performance. The diisocyanate chain is composed of hard chain segment, so that the molecular chain will not extend indefinitely, prevent the sliding between molecules, so that the fiber has high resilience and strength. In fibers, soft segments form a liquid-like base, while hard segments form a hard region and act as crosslinking. The basic structure of the fiber follows the typical rubber elastic theory. There are only weak intermolecular forces like liquids between the long chain segments that can move freely. The three-dimensional network is formed by the cross-linking of specific sites, which is realized by the crystalline hard segments in the hard region.
