Abstract

The invention discloses fiber with relatively high stretch rate and a preparation method thereof, and relates to the technical field of textile materials. The preparation method comprises the following steps of firstly drying polytrimethylene terephthalate slices and polyethylene glycol terephthalate slices, and carrying out melt extrusion to obtain a polytrimethylene terephthalate spinning material and a polyethylene glycol terephthalate spinning material; adding the polytrimethylene terephthalate spinning material and the polyethylene glycol terephthalate spinning material into a composite spinning assembly according to a mass ratio of 1: 1, performing spinning to obtain fibril, then stretching the fibril in a stretching bath containing esterified polysiloxane and pretreated silicon dioxide to obtain a fiber blank; and finally, soaking the fiber blank in dispersion liquid of a modified linear styrene-butadiene-styrene block copolymer, and performing curing in a light curing machine to obtain the high-stretch-rate fiber. The high-stretch-rate fiber prepared by the method has excellent elasticity and relatively high stretch rate.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to a fiber with a high elongation rate and a preparation method thereof. Background technique [0002] With the progress of society, the development of science and technology and the improvement of living standards, people's clothing consumption concept and market demand have undergone significant changes. The requirements for fibers and textiles are not only durable and beautiful, but also the pursuit of textiles. Wearing comfort, health, safety protection and environmental protection. Cellulose fiber is made from natural materials and has excellent properties such as good hygroscopicity, strong air permeability, comfortable wearing, easy dyeing, and natural environmental protection. It meets people's requirements for comfort, environmental protection and health, and is favored by consumers. However, the wrinkle resistance of cellulose fiber is poor, and its fabric has d...
