preparation example Construction

[0029] Correspondingly, an embodiment of the present invention provides a method for preparing a moisture-permeable and quick-drying composite yarn, comprising the following steps:

[0030] S1, the raw cotton staple fiber is subjected to the cotton opening and cleaning process to make cotton bundles;

[0031] mixing and dissolving cellulose acetate powder and acrylic acid powder in a solvent to obtain a spinning solution; the solvent is one or more of acetone and N,N-dimethylacetamide;

[0032] S2. Carding the cotton bundles obtained in step S1, during the process of carding to form a cotton web, electrospinning the spinning solution, so that the formed micro-nano fibers are combined with the cotton web to make a composite sliver ; The mass percentage of the micro-nano fiber in the composite sliver is 8-10%;

[0033] S3. The composite sliver obtained in step S2 is sequentially combed, drawn, roved and spun to obtain a moisture-conducting and quick-drying composite yarn.

Embodiment 1

[0053] The production method of a moisture-conducting and quick-drying knitted fabric described in this embodiment is as follows:

[0054] (1) Mix the raw cotton staple fiber with cotton, and then perform the cotton opening and cleaning process to make a uniform cotton lap. After opening and cleaning, the impurity content of the laps is controlled below 1%, and the unevenness of the laps is controlled below 1%.

[0055] (2) cellulose acetate (CA-398-3 produced by American Eastman Company, acetylation degree 39.8%, average molecular weight 35000) is dissolved in a solvent, and stirred at room temperature to obtain a cellulose acetate solution; wherein, the solvent is Acetone / N, N-dimethylacetamide (volume ratio 2:1); During the stirring process, add acrylic acid powder to the cellulose acetate solution, the mass ratio of acrylic acid / cellulose acetate is 10 / 90, in Stir and dissolve at 40°C, the stirring speed is 2000r / h, and the stirring time is 10h to obtain a spinning soluti...

Embodiment 2

[0079] The production method of a moisture-conducting and quick-drying knitted fabric described in this embodiment is as follows:

[0080] (1) Mix the raw cotton staple fiber with cotton, and then perform the cotton opening and cleaning process to make a uniform cotton lap. After opening and cleaning, the impurity content of the laps is controlled below 1%, and the unevenness of the laps is controlled below 1%.

[0081] (2) Dissolving cellulose acetate (CA-398-10 produced by American Eastman Company, acetylation degree 39.8%, average molecular weight 40000) in N, N-dimethylformamide, stirred at room temperature to obtain acetic acid Cellulose solution; during the stirring process, add acrylic acid powder to the cellulose acetate solution, the mass ratio of acrylic acid / cellulose acetate is 15 / 85, stir and dissolve at 40°C, the stirring speed is 2000r / h, the stirring time 10h to obtain a spinning solution; the mass concentration of the spinning solution is 14wt%, the surface t...

Abstract

The invention provides a moisture-conducting and quick-drying composite yarn, its preparation method and fabric, the composite yarn is obtained by composite spinning of micro-nano fiber and cotton fiber; the micro-nano fiber component is acrylic acid modified cellulose acetate ; The mass percentage of the micro-nano fiber in the composite yarn is 8-10%. The acrylic-modified cellulose acetate micro-nano fiber of the present invention has excellent hygroscopicity and a large specific surface area, and when the human body sweats, the sweat can be quickly exported and evaporated through the differential capillary effect brought by it. , so that the moisture transfer and quick-drying properties of cotton-type yarns are greatly enhanced. Moreover, controlling the specific proportion of the micro-nano fibers in the composite yarn optimally balances the moisture-conducting and quick-drying ability of the yarn and the uniformity of distribution of the micro-nano fibers. The invention mainly improves the moisture-wicking and quick-drying properties of yarns and fabrics through physical methods, has long-lasting functions, and has no influence on the comfort of the fabrics produced. In addition, the preparation method of the present invention is simple and efficient.

Description

technical field [0001] The invention relates to the technical field of clothing fabrics, in particular to a moisture-conducting and quick-drying composite yarn, a preparation method thereof and fabrics. Background technique [0002] In recent years, with the improvement of the quality of life, the Chinese sports market has grown rapidly. More and more people are participating in daily fitness activities such as fitness, running, and yoga. The demand and requirements for sportswear are getting higher and higher, especially the comfort of clothing sex and environmental protection. Therefore, the development of environmentally friendly clothing fabrics based on cotton fibers has become a hot spot in the research and development of major sports brands. [0003] Cotton fiber comes from nature and is a natural and environmentally friendly fiber. It has good hygroscopicity and is skin-friendly, so it is very suitable for wearing next to the skin. However, when the human body swea...
