Abstract

The invention discloses a production process for airflow-spinning stocking yarns, which comprises the following steps: performing airflow-spinning on a main fiber raw material after the step of blowing-carding, or the blowing-carding and drawing, or blowing, cotton carding and the drawing, or the blowing, the cotton carding, pre-drawing, sliver lap and the drawing, or a cross step of the four modes so as to form airflow spinning; before performing the step of the airflow spinning, adding water-soluble fibers into the main fibers; and after performing the step of the airflow spinning, performing knitting processing to form knitted fabrics, and using hot water to dissolve the water-soluble fibers in the knitted fabrics to obtain airflow-spinning knitted fabrics. The airflow-spinning stocking yarns produced by the process not only has even yarn levelness, smooth appearance and fewer hair feathers, but also soft knitted fabric hand feeling after the water-soluble fibers are dissolved, thereby sufficiently satisfying the processing requirements of knitting apparel textiles, improving the processing performance of the airflow spinning, and expanding the application range of the airflow spinning.

Description

technical field

[0001] The invention relates to a production process of knitting yarn, in particular to a production process of air spinning knitting yarn, which belongs to the textile field. Background technique

[0002] As we all know, the textile industry is a traditional industry of our country, and our country is the largest country in the production and export of textiles in the world. The current global financial tsunami has had a serious impact on the textile industry. The textile industry is facing the pressure of survival and the opportunity of development. , Continuous innovation is the development trend of the textile industry. In recent years, my country's textile industry has made great progress in the invention and application of new materials and new technologies.

[0003] In the textile industry, a new textile method was developed after 1950, that is, air spinning is also called rotor spinning, and the yarn produced by it is called air spinning or OE yarn. ...

Examples

specific Embodiment approach

[0018] figure 2 It is a flow chart of the production process of the air spinning knitting yarn described in the present invention.

[0019] Such as figure 2 Shown:

Embodiment 1

[0021] A kind of production technology of air spinning knitting yarn, comprises the following steps:

[0022] In the processing step of cleaning and carding the main fiber, namely cotton, water-soluble fiber, namely water-soluble polyvinyl alcohol (PVA), is added, mixed and processed for cleaning and carding, air spinning, and then knitting to form knitted fabrics. Dissolve the water-soluble fiber therein with hot water, and then dry to obtain a very soft and smooth air-spun knitting yarn, and the dry weight percentage of the above-mentioned water-soluble polyvinyl alcohol in the air-spun knitting yarn is 2.5%.

Embodiment 2

[0024] A kind of production technology of air spinning knitting yarn, comprises the following steps:

[0025] In the cleaning process of the main fiber, that is, hemp, water-soluble fiber, that is, water-soluble polyvinyl alcohol (PVA), is added, and after mixing, it is cleaned, carded, drawn, and then air-spun, and finally formed by knitting. After knitting, hot water is used to dissolve the water-soluble fiber therein, and after drying, a very soft and smooth air-spun knitting yarn is obtained, and the dry weight percentage of the above-mentioned water-soluble polyvinyl alcohol in the air-spun knitting yarn is 30%.
