Super elastic flame-retardant coarse denier porous PET-DTY process method

Abstract

The invention relates to a super elastic flame-retardant coarse denier porous PET-DTY process method. The process method comprises the following steps of flux manufacturing, high-efficiency mixing, filtration, cooling solidification, PET-POY manufacturing, and winding. Through the steps of flux manufacturing, high-efficiency mixing, filtration, cooling solidification, and PET-POY manufacturing, broken filament of PET-POY is reduced so broken filaments processed into the PET-DTY are reduced; the process of the PET-DTY is further adjusted, residual torque is lowered, and the unwinding success rate of products is improved; and the problems of unwinding difficulty, multiple broken ends and idle stop of a weaving machine are solved, so quality control of the products is stable, defects on a cloth cover are reduced, the production efficiency is high, and the products have the advantages of high elasticity, high flame-retardant performance, softness and breathability.

Description

technical field [0001] The invention relates to the technical field of polyester fibers, in particular to a process method of superelastic flame retardant coarse denier porous PET-DTY. Background technique [0002] Coarse denier porous PET-DTY is a kind of helically crimped fluffy elastic fiber, the style of the fiber can be changed by physical methods, such as turning off the heating function of the heating box of the texturizing machine, the obtained DTY has a large elastic stretch rate, elastic stretch It is also called super-elastic DTY with a rate of more than 30%; by adding functional ingredients, such as antistatic agents, flame retardants, hydrophilic agents, antibacterial agents, etc., the fibers can be endowed with differentiated functions to meet the diverse needs of customers. The addition of reagents will cause changes in the internal molecular structure of the fiber, and the tensile strength of the fiber macromolecules will become weaker, and broken filaments w...

Problems solved by technology

[0004] The purpose of the present invention is to address the deficiencies of the prior art, to provide a process method of super-elastic flame-retardant coarse denier porous PET-DTY, through the production of functional flame-retardant masterbatch melt, efficient mixing, filtration, cooling and solidification , the production of super-elastic flame-retardant coarse denier porous PET-POY, the winding step reduces the wool of PET-POY, so that the wool of PET-DTY is reduced, and the process of PET-DTY is further adjusted to reduce the residual torque and improve It improves the unwinding success rate of the product, solves the problems of difficult unwinding, many end breaks, and idle stop of the loom, so that the product quality control is stable, the cloth surface has fewer defects, the production efficiency is high, the product has high elasticity and flame retardancy, and is soft.
