Problems solved by technology

As seen from the above-mentioned prior art, most of the seaweed polyester fibers are attached to the textile fibers through post-treatment, but with daily use, washing, etc., the modification effect of the fiber surface will gradually decrease. or even disappear, functionality is not durable
[0006] At the same time, due to the addition of seaweed extract, the high hydrophilic property of seaweed extract causes the abnormal problems of high boiling water shrinkage and uneven dyeing of the prepared polyester fiber, which affects the spinning performance

Abstract

The invention provides seaweed polyester fiber. The fiber is characterized in that the raw materials comprise polyester slices, seaweed extract, a modifier and a regulator which are in a mass ratio being (90-110):(3.3-5.7):(4.1-6.2):(3-5). According to the seaweed polyester fiber, the seaweed extract is added, so that the prepared seaweed polyester fiber has good moisture absorption and skin affinity, has lower boiling water shrinkage rate besides good moisture absorption, the boiling water shrinkage rate is lower than or equal to 0.5%, and the problem of technical prejudice is solved.

Description

technical field [0001] The invention relates to a seaweed polyester fiber and a preparation method thereof, belonging to the field of fiber technology. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. Since its inception, polyester products have also been used by downstream users as the main textile raw material for weaving various textiles due to their good drapability, high strength and crispness. With the globalization of the economy and the internationalization of the market, people's requirements for clothing are getting higher and higher. Not only must they be comfortable, but they must also be functional. It is necessary to continuously improve performance to meet weaving requirements. The polyester industry in my country has developed rapidly. The output of polyester fiber has grown from 5.165 million ...
