Problems solved by technology

[0004] However, the fabrics made of traditional thermal storage and temperature-regulating fibers have high specific resistance, low specific gravity, fluffy and smooth surface, and low cohesion between fibers. Static electricity is easily generated during spinning, and sticking, entanglement, winding, blocking, etc. problem, difficult to spin into yarn
In particular, some of the phase-change microcapsules may be squeezed and ruptured during carding, drawing, and other processes of heat-storage and temperature-regulating fibers. On the other hand, the phase change material overflowed after the microcapsules break is in a liquid state at room temperature, causing sticking between fibers and fibers, and between fibers and spinning parts, which brings difficulties to spinning

Abstract

The invention discloses a fiber fabric with the function of heat storage and temperature adjustment, which is made by blending raw materials with the following weight percentage ratio: 30-50% viscose-based heat storage and temperature-regulation fiber, 10-30% cotton Fiber, 10‑30% Modal, 20‑40% Linen and 10‑30% Polyester. The present invention proposes a fiber fabric with heat storage and temperature regulation function. The fabric is made of viscose-based heat storage and temperature regulation fiber blended with other suitable fibers. The spinning is smooth and the excellent characteristics of each fiber can be fully utilized. The obtained fabric not only obtains the best temperature-regulating effect, but also has good heat storage and temperature-regulating performance and mechanical properties, and is suitable for industrial implementation.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a fiber fabric with heat storage and temperature adjustment functions. Background technique [0002] As consumers' requirements for clothing gradually tend to be diversified and multifunctional, heat storage and temperature regulating fabrics are one of the key products to be developed. Because the heat transfer of clothing can basically be divided into two types: sensible heat transfer, that is, the heat transfer that can be generated by the difference between the human body temperature and the external environment, which is mainly completed through heat conduction, convection and radiation; latent heat transfer, that is, due to the difference between the human body and the external environment The moisture heat transfer caused by the difference in vapor concentration between the two is mainly completed by evaporation and perspiration. With the fashion of clothing, it is not on...
