Problems solved by technology

[0003] A kind of production method of elastic denim fabric with low shrinkage rate described in the notification number CN 10701256A, the specific steps include spinning, dyeing, sizing, weaving and finishing, adopting cotton / viscose blended warp yarn to weave denim fabric, finishing The use of loose soft finishing technology reduces the weft shrinkage of the fabric and improves the elasticity of the denim fabric, but it does not significantly improve the cold-proof function of the denim fabric, and cannot improve the thermal insulation and heat storage functions of the denim fabric.
[0004] In the wear-resistant soft denim fabric described in the notification number CN 107523909A and its preparation method, the raw materials of the denim fabric include cotton, bamboo fiber, tencel and spandex, which can provide a kind of wear-resistant good, soft hand feeling, texture Light and slippery denim fabric, although the fabric is moisture-wicking and breathable, it does not have a good warmth retention effect, so it is not suitable for autumn and winter wear
[0005] The notification number CN 207630649U describes a windproof denim fabric, the denim fabric comprises a denim fabric body, a windproof fabric layer on the outside of the body, and a cotton and linen blended layer on the inside, which prevents the wind from blowing directly to the human body surface to keep warm effect, but the application may be limited in low temperatures with no wind

Abstract

The invention relates to a multi-fiber jean fabric and a production method therefor, and belongs to the technical field of textiles. The multi-fiber jean fabric is prepared through the blending of five kinds of raw materials of tencel fiber, volcanic rock fiber, acrylic fiber, cotton fiber and spandex fiber. The mass percentages of the five raw materials is 25 to 35% of volcanic rock, 10 to 15% oftencel fiber, 6 to 9% of acrylic fiber, 40 to 60% of cotton fiber, and 0.5 to 1.5% of spandex fiber. The process sequence includes: feeding, blowing, carding, roving, spinning, dyeing, weaving, pre-shrinking, and raising. The invention has the beneficial effects that the new volcanic rock fiber is added to improve the warmth of the fabric, and the denim fabric obtained by blending the five raw materials realizes the complementary advantages of different fibers, and has the functions of keeping warm and feeling comfortable, breathable and bacteriostatic; the method adopts a reasonable processto improve the blending uniformity; the process is optimized to obtain better gloss and color fastness; the heat retention rate is 25 to 35%, the heat storage rate is greater than 40%, and the physical index of the fabric is stable; a better taking effect is obtained.
