preparation example Construction

[0027] The preparation method of described functional spandex comprises the following steps:

[0028] (1) Weighing of raw materials: take functional jade powder, isocyanate, oligomer diol, chain extender, auxiliary agent, solvent, chain terminator of corresponding weight parts, and set aside;

[0029] (2) Preparation of functional jade powder slurry: circularly grind functional jade powder, additives and solvent in a grinder for 30-40 hours to obtain dispersed functional jade powder slurry;

[0030] (3) Preparation of prepolymer solution: Stir and mix isocyanate and oligomer diol at 70-80°C for 1-2h to prepare prepolymer; after cooling the prepolymer to 40-60°C, add A solvent is prepared to obtain a prepolymer solution with a mass concentration of 36-40%;

[0031] (4) Preparation of polyurethane urea: Dissolve the chain extender and chain terminator in the solvent to form a reaction solution with a mass concentration of 7.2-8%, and add the reaction solution to the prepolymer ...

Abstract

The invention relates to the field of spinning, in particular to a cool elastic denim fabric and a preparation method thereof. The cool elastic denim fabric is formed by interweaving warp yarns and weft yarns, wherein the warp yarns are composed of first component warp yarns and second component warp yarns, and the first component warp yarns are yarns formed by blending functional spandex, cotton fibers and bamboo fibers; the second component warp yarns are yarns formed by blending cotton fibers and functional spandex; the weft yarns are functional spandex core-spun yarns wrapped by blended yarns of cotton fibers and bamboo fibers; and the functional spandex is prepared from the following raw materials of functional jade powder, isocyanate, oligomer dihydric alcohol, a chain extender, a solvent, a chain terminator and an auxiliary agent. The functional jade powder is utilized to prepare the functional spandex, and the functional spandex enables the fabric to have elasticity, breathability, cool feeling and good comfort.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a cool elastic denim fabric and a preparation method thereof. Background technique [0002] With the growth of social economy, people's quality of life is also constantly improving, and people's requirements for clothing are no longer from basic functions such as body covering, body protection, and cold protection to functional, health, environmental protection, and comfort. , the cool breathability of the fabric is also increasing. Denim fabric is a fashionable and popular clothing fabric, and cool and breathable denim fabric is becoming more and more popular, especially when wearing clothes made of cool and breathable fabrics when exercising, the clothes made of cool and breathable fabrics make people feel more comfortable. The experience is better. The continuous emergence of high-end fiber materials has brought huge room for improvement to the development of denim fabrics. Giving d...
