Light covered yarn with warmth-keeping and cooling functions and preparation method of yarn

Abstract

The invention discloses light covered yarn with warmth-keeping and cooling functions. The yarn comprises core yarn and covering yarn covering the outer layer of the core yarn, wherein the covering yarn is made of two kinds of synthesized polyester yarn adopting different structures and having specially-shaped sections, one kind has round hollow sections, and the other kind has star-like hollow sections; the core yarn is spandex yarn. The invention further provides a preparation method for producing the covered yarn. The light covered yarn with the warmth-keeping and cooling functions is prepared with the method, yarn having the specially-shaped sections is synthesized, one kind has the hollow sections, the body temperature is kept relatively stable when the external environment is changed, warmth can be kept in cold winter, a user can have the cool feeling in hot summer, and the yarn has the characteristics of moisture absorption, quick dryness and lightness.

Description

technical field [0001] The invention relates to a covered yarn and a preparation method thereof, in particular to a lightweight covered yarn with functions of keeping warm and cool and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the quickening pace of life, people's requirements for clothing are getting higher and higher. Fitting, comfort, softness and elasticity have become the pursuit goals of new clothing fabrics. Therefore, spandex elastic fabric has become a new favorite in clothing. [0003] Spandex covered yarn is one of spandex elastic yarn varieties. Spandex covered yarn is an elastic yarn formed by covering the elongated spandex yarn with the spandex yarn as the core, and wrapping the elongated spandex yarn with the filament or short fiber yarn in a spiral manner. According to the number of covering layers, it can be divided into two types: single covering yarn and double covering yarn. Among t...

Problems solved by technology

[0004] The existing ordinary spandex covered yarn has a single circular cross-section, low twist in the process, poor yarn covering effect, relatively heavy yarn quality, poor air permeability and average warmth retention.

When worn in winter, this kind of yarn is relatively rough and does not keep warm; when worn in summer, the air permeability is poor, the human body feels stuffy, and the perspiration is not smooth
