Problems solved by technology

[0006] Aiming at the technical problem that the ultra-low proportion blended yarn cannot be produced by the existing drawing frame blending production process, the present invention provides an ultra-low proportion blending process and its yarn preparation method. The present invention adopts A The / A+B blending process method realizes the production of ultra-low-ratio blended yarns, breaking the pattern that the existing production technology cannot produce ultra-low-ratio blended varieties through drawing and bar blending; the invention effectively reduces the labor intensity of workers and improves production Efficiency makes the blending ratio of the product more accurate, the grade of the product is further improved, and provides a broad space for the development and expansion of subsequent functional products

Embodiment 1

[0036] Such as figure 1 As shown, an ultra-low ratio combed cotton / water-soluble polyester fiber 40-inch yarn, the blending ratio of combed cotton fiber and water-soluble polyester fiber is 97:3, and the preparation method includes the following steps:

[0037] 1. Production process of cotton fiber strip

[0038] (1) Cotton: 100% SUpima, horse cotton is American high-quality long-staple cotton, with long fiber length, high fiber strength and good gloss;

[0039] (2) Blowing: temperature 23℃, humidity 72%, adopting the process principle of "grasp less frequently, fall early and less broken, more loose and less beaten", FA002 cotton grabbing machine beater speed 720r / min, cotton opener FA106 beater speed 560r / min, single beater coiling machine A076F beater speed 960r / min, fan speed 1040r / min, beater descending speed 3mm / circle, clear pound weight 480g / m;

[0040] (3) Carding: temperature 29℃, humidity 62%, adopting the process principle of "light weight, slow speed, slow flat speed", a...

Embodiment 2

[0063] An ultra-low ratio combed cotton / water-soluble polyester fiber 32-inch yarn, the blending ratio of combed cotton fiber and water-soluble polyester fiber is 95:5, and the preparation method includes the following steps:

[0064] 1. Production process of cotton fiber strip

[0065] (1) Cotton: 100% SUpima, horse cotton is American high-quality long-staple cotton, with long fiber length, high fiber strength and good gloss;

[0066] (2) Blowing: the temperature is 25℃, the humidity is 68%, adopting the process principle of "grasp less frequently, fall early and less broken, more loose and less beaten", FA002 cotton grasper beater speed 720r / min, cotton opener FA106 beater speed 560r / min, single beater coiling machine A076F beater speed 960r / min, fan speed 1040r / min, beater descending speed 3mm / circle, clear pound weight 450g / m;

[0067] (3) Carding: the temperature is 30℃, the humidity is 58%, the process principle of "light weight, slow speed, slow flat speed" is adopted, the gap ...

Abstract

The invention relates to the technical field of spinning, in particular to an ultralow-proportion blending process and a method for preparing yarn through the blending process. A fiber strip a and a fiber strip b are adopted in the blending process, the fiber strip b accounts for 3%-7% of the total mass of the fiber, the blending process comprises three drawing steps, the first drawing step is tomix the fiber strip a and the fiber strip b to prepare a strip A, the second drawing step is to mix the strip A and the fiber strip a to prepare A + B strip, and the third drawing step is to mix the A+ B strip; the yarn preparation method comprises roving, spinning and spooling of blended card slivers. According to the invention, an A / A + B blending process mode is adopted in the drawing process,so that ultralow-proportion blended yarn production is realized, the labor intensity of workers can be effectively reduced, the production efficiency is improved, the blending proportion of the product is more accurate, the grade of the product is further improved, and a wider space is provided for the development and expansion of subsequent functional products.

Description

Technical field [0001] The invention relates to the technical field of spinning, in particular to an ultra-low ratio blending process and a method for preparing yarn by using the blending process. Background technique [0002] With the continuous development of society and economy, people’s living standards are improving day by day, and the clothing industry, which is the primary position of clothing, food, housing, and transportation, is undergoing rapid changes. The functional requirements of fabric products are constantly increasing. They are blended with two or more fibers. The yarn can give the fabric more special functionality, so it is often used to weave high-end clothing. [0003] Ultra-low ratio blended yarn refers to a yarn whose blending ratio of a certain fiber in the blended yarn is less than 10%. This kind of yarn can meet the special fiber properties and fabric style. The existing draw frame blending production process usually includes three-pass blending. The blen...
