Abstract

The invention belongs to the technical field of textile fiber manufacture and discloses a preparation method of a thermal insulation fiber. The method comprises the steps of material preparation, spinning stock solution preparation, spinning, post treatment and the like. A certain quantity of water-soluble polymers are added to raw materials, the water-soluble polymers in the spun fiber are removed by water washing in post treatment, and the thermal insulation fiber with a rich pore structure is obtained. The thermal insulation fiber prepared with the method maintains the original characteristics of excellent crease resistance, elasticity and dimensional stability, resistance to sunlight, friction, mildew and moth, better chemical reagent resistance, fastness, durability, non-sticking andthe like of a polyester fiber, and thermal insulation performance of the polyester fiber is improved on the premise, so that the polyester fiber has good thermal insulation performance.

Description

technical field [0001] The invention relates to the technical field of textile fiber manufacturing, in particular to a method for preparing thermal fiber. Background technique [0002] Polyethylene terephthalate fiber, also known as polyester fiber, has excellent wrinkle resistance, elasticity and dimensional stability, sunlight resistance, friction resistance, mildew and moth resistance, and good chemical resistance. It has the characteristics of being durable and non-sticky, and can be blended with natural fibers or purely spun according to different application requirements. The obtained textiles can be widely used in decoration, clothing and other fields. [0003] However, polyester fiber also has disadvantages such as poor thermal performance, and its use is limited to a certain extent. Therefore, the thermal insulation modification of polyester fiber is of great significance. Contents of the invention [0004] In order to solve the above problems, the present invent...
