A kind of preparation method of phase change fiber

Abstract

The invention discloses a preparation method of a phase change fiber. The preparation method comprises the steps of (1) preparing a microcapsule phase change material; (2) preparing a sensible heat or latent heat composite energy storage phase change material; (3) spinning the microcapsule phase change material prepared in the step (1) and the sensible heat or latent heat composite energy storage phase change material prepared in the step (2) and a polymer solution together to obtain the phase change fiber, wherein the adding quantity of each of the microcapsule phase change material and the sensible heat or latent heat composite energy storage phase change material is 5-10% and 5-7% of the mass of the polymer solution respectively. By adding the microcapsule phase change material into a spinning solution, the phase change fiber has the advantages of uniform material dispersion and significant temperature adjustment performance, the phase change fiber can not overflow and lose the phase change performance during wearing, washing and ironing of clothes produced by the phase change fiber, and the sensible heat or latent heat composite energy storage phase change material is added to the spinning solution, so that the oxidation resistance and the moisture retention of the phase change fiber are significantly improved, and the warm-keeping rate is improved by 30-50%.

Description

technical field [0001] The invention relates to a method for producing fiber fabrics, in particular to a method for preparing phase-change fibers, and belongs to the technical field of textile technology. Background technique [0002] With the improvement of people's living standards, the requirements for wearing fiber products are getting higher and higher, especially some sportswear, which have relatively high temperature requirements and need to have a two-way temperature adjustment function, while the storage of traditional phase change fibers The thermal performance is not durable, the number of cycles is small, and the practicability is not strong. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a preparation method of a phase-change fiber with good applicability, strong adjustment ability, and durability. [0004] To achieve the above object, the present invention is achieved...
