Multifunctional comfort fiber with functions of phase transition temperature regulation, moisture absorption and moisture wicking

Abstract

The invention relates to multifunctional comfort fiber with functions of phase transition temperature regulation, moisture absorption and moisture wicking. According to the fiber, an interpenetrating network composite phase transition material is adopted as a heat storage and temperature regulation material, a fiber-forming polymer is adopted as a matrix, a pore-forming agent and a compatibilizer are added to prepare a spinning raw material, and a melt spinning process is adopted to prepare the multifunctional comfort fiber. The spinning raw material preparation method comprises: mixing the interpenetrating network composite phase transition material and the fiber-forming polymer according to a mass ratio of (95-60):(5-40), then adding the pore-forming agent and the compatibilizer, and uniformly mixing, wherein the mass of the pore-forming agent is 0-10% of the total mass of the interpenetrating network composite phase transition material and the fiber-forming polymer, the mass of the compatibilizer is 1-5% of the total mass of the interpenetrating network composite phase transition material and the fiber-forming polymer, the pore-forming agent is the PEG with the molecular weight of 1000-2000, the compatibilizer is one or a plurality of materials selected from PP-g-PEGA, PP-g-PEG, PET-g-PEGA, PEGA, montmorillonite, and the like. The phase transition temperature range of the multifunctional comfort fiber is 30-55 DEG C, the melting phase transition enthalpy is 5.24-29.12 J / g, the breaking strength is 3.0-3.5 cN / dex, and the thermal decomposition temperature is more than 400 DEG C.

Description

technical field [0001] The invention relates to functional fiber technology, in particular to a comfortable fiber with not only thermal energy storage and release, but also moisture absorption and perspiration function, and good comprehensive performance. Background technique [0002] In recent years, with the continuous development of phase change materials, taking advantage of the characteristics of high phase change latent heat of phase change materials, approximately constant temperature during the phase change process, small volume change, and easy control of the process, it can be applied to the production of phase change fibers and can be developed Multifunctional and diverse phase change fibers. The phase change fiber can freely adjust the internal temperature of the textile within a certain temperature range according to the change of the external environment temperature. When the external environment temperature rises, it can store energy; Less, people will feel m...

Problems solved by technology

[0003] With the improvement of living standards, people have higher and higher requirements for textiles. While pursuing comfort, they pay more and more attention to the functionalization of textiles, and then require more and more functions for fibers. Single function It can no longer meet people's needs, and people are constantly pursuing multifunctional fibers
