Description

High ventilative fluffy type nitrile brocade elongation wool yarn

Technical Field

The utility model relates to the technical field of textile yarns, in particular to a high-breathability fluffy acrylic brocade drawn wool yarn.

Background

The acrylic fiber is polyacrylonitrile fiber, and the main repeating unit is-CH 2-CH (CN) -. The macromolecules of the acrylon are in irregular spiral conformation, do not have strict crystal regions and belong to quasicrystal structures. Pure polyacrylonitrile can form a good crystalline structure, cyano groups with strong molecular lateral action form stable interaction and arrangement, so that fibers become brittle and hard, the dyeing property is poor, and a second monomer and a third monomer must be added. The macromolecular structure of the material is softened by adding the second monomer, and the axial ordering of the molecules and the lateral ordering among the molecules are weakened, so that the elasticity and the hand feeling of the material are improved; about 1% of a third monomer is added to improve the dyeability of the fiber. Nylon was developed by the outstanding scientist caroth in the united states and a research group leading behind it, and was the first synthetic fiber appearing in the world, nylon being one of the terms polyamide fiber (chinlon). The appearance of nylon makes the appearance of the textile brand-new, and the synthesis of the nylon is a great breakthrough of the synthetic fiber industry and is also a very important milestone of high polymer chemistry. The acrylic fiber has excellent heat retention and bulk, is widely applied to various wools, but has poor wear resistance, the pure-spinning wools are not durable, and the acrylic fiber is generally selected to be blended with wear-resistant fibers, such as nylon fiber, but the blended yarn loses part of the excellent characteristics of the acrylic fiber, so that the air permeability, bulk and structural strength of the yarn are relatively poor. Therefore, it is desirable to provide a new type of nitrile nylon yarn with good air permeability and bulk.
