Regenerated fiber is an Oxford fabric made from natural polymers through chemical methods
There are three main types of regenerated fibers: viscose fiber, acetate fiber and cupro fiber. Nowadays, there are many bamboo fibers, milk fibers, soybean fibers, etc., which are all regenerated fibers, but generally the regenerated fibers on the label are simply Viscose fiber, also known as artificial cotton. This label is not very standardized and is a bit misleading to consumers. It is deliberately misleading.

It is basically the same chemical group as the original polymer. For natural polymers, this requires purification to remove impurities. For example, the polymer used to make viscose fiber is cellulose. Cellulose is purified from cellulose raw materials such as velvet, wood, reeds, and bagasse to make pulp, and then the pulp is used to make fiber.
Synthetic fiber polymers are obtained by chemical addition or condensation polymerization using low molecular compounds (monomers) obtained from coal, petroleum, natural gas, agricultural and sideline products, etc. as raw materials. Synthetic fibers are obtained by processing the polymer. Therefore, synthetic fibers are often named by their polymer monomers, with “poly” added in front of the monomer.
Preparation of spinning fluid
Before spinning fiber-forming polymers, a certain method must be used to prepare the spinning fluid. At present, the commonly used methods include melt method and molten liquid method

What kind of fabric is recycled fiber? Is it harmful to the human body when worn?
Plant-based regenerated fiber is made by dissolving cellulose such as straw and bark and then spinning it. Viscose fiber is commonly used. It has good hygroscopicity (standard moisture regain rate is 14%), good air permeability, and is more comfortable to wear. In addition, There are also some regenerated fiber fabrics such as acetate fiber and cupro fiber (standard moisture regain is about 4%). Although they have good moisture absorption and air permeability, their strength will decrease significantly after absorbing sweat or washing. If the strength decreases, the clothes will be easily damaged.
In recent years, several new fiber varieties with very good performance have been born in the field of regenerated fibers, such as Modal, Tencel and Lyocell. They will be the main direction for the development of regenerated fibers in the future. In addition, fabric products such as chitin fiber (safe, non-toxic, and has a certain antibacterial effect) and soy protein fiber (regenerated plant protein fiber) independently developed by my country and the first to be industrialized are also gradually entering the public’s life. s0kulVzT
