Friction-spun phase-change antistatic composite yarn and preparation method thereof

Abstract

The invention relates to a friction-spun phase-change antistatic composite yarn and a preparation method thereof. The method comprises the following steps of 1, sequentially impregnating a polyester yarn in a mixture of polyethylene glycol (PEG) and carbon nanotubes, and a polyvinyl butyral (PVB) solution to obtain a polyester-PEG-carbon nanotube-PVB composite yarn; and 2, taking the polyester-PEG-carbon nanotube-PVB composite yarn as a core yarn and common synthetic fibers as wrapping fibers, and performing friction spinning to prepare the polyester-PEG-carbon nanotube-PVB-synthetic fiber composite yarn. The composite yarn has the advantages that 1, the composite yarn is high in phase change enthalpy value, good in heat storage effect, high in heat transfer efficiency and good in antistatic property; 2, the preparation method is simple, economical and rapid; 3, the service life is long, and the thermal cycle performance is stable; 4, the phase change temperature is adjustable; and 5,the raw material applicability is good, and the problem that a core yarn is difficult to prepare by ring spinning after non-uniform PEG sizing can be solved.

AI Technical Summary

Problems solved by technology

However, these preparation technologies are not very perfect, and there are problems such as low content of phase change substances, poor thermal cycle performance, high production cost, and difficulty in large-scale promotion.

In contrast, a preparation method of phase change heat storage core-spun yarn invented by Jiang Ming et al. of Wuhan Textile University (application number: CN107460587A) can achieve high adsorption of phase change materials, but the ring spinning or rotary spinning they use Cup spinning has the problems of difficult spinning and complex spinning process, which limits the large-scale development, and there are also problems such as poor thermal conductivity of core-spun yarn and easy leakage of phase change materials.
