Textile with temperature regulating function and preparation method thereof

Abstract

The invention provides a textile with a temperature regulating function and a preparation method thereof. The surface of a textile body is coated with printing paste by means of a printing process andthen dried. In the method, the textile is coated and finished by selecting a phase change material as a functional finishing agent to obtain the textile with the temperature regulating function. Thetextile absorbs heat when the ambient temperature rises and lowers the internal temperature of a garment; when the ambient temperature is lowered, heat is released, and the internal temperature of thegarment rises, so that a comfortable effect is still maintained on the skin during violent change of the ambient temperature.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a temperature-regulating textile and a production method thereof. Background technique [0002] With the development of the economy and the improvement of people's quality of life, people's pursuit of daily necessities is becoming more and more diversified, and the requirements for the comfort of textiles are increasing. More and more consumers are pursuing "comfort, health and beauty", such as temperature adjustment Features. When the weather turns cold, the traditional method is to increase the number and thickness of textiles or use down to keep warm. This kind of thick and bloated textile makes the user feel inconvenient when exercising; and after exercising, a large amount of sweat is difficult to get rid of in time, which easily causes a feeling of dampness and even a cold. [0003] Phase-change temperature-adjusting textile is a new product that increases the comfort of wearing. ...

AI Technical Summary

Problems solved by technology

The printing technique has the following problems: one, poor air permeability: the temperature-regulating microcapsules have no affinity with textiles, and adhesives must be used to connect the two together, and the consumption of the cross-linking agent in the prior open technology accounts for more than 50% of the microcapsules , a large amount of cross-linking agent covers the surface of the fabric, hindering the penetration of air, making the textile poor in air permeability, and retaining a certain amount of organic solvent

Second, the pattern is limited, a large amount of adhesive is coated on the surface of the fabric, which makes the fabric feel hard, which can only be improved by partial printing, which limits the style of the pattern

Third, strong greasy feeling: During the printing and drying process, due to the high temperature or excessive pressure of the roller, the phase change microcapsules are broken, and the core material is directly attached to the fabric, resulting in a greasy feeling

Fourth, the temperature adjustment effect is poor: due to the rupture of the phase change material during the production process, the core material volatilizes during the baking process, resulting in poor heat absorption effect of textiles, small enthalpy per unit area of ​​textiles, and poor temperature adjustment function

Fifth, the production process is complicated and the energy consumption in the production process is high
