Problems solved by technology

Since this technology is based on the treatment of the yarn, and the waterproofing agent is usually a macromolecular chemical polymer, it is difficult to achieve uniform treatment in the inner and outer layers of the package yarn, which will easily cause color differences between the inner and outer layers, and the inner and outer layers of yarns will be repellent. The difference in water effect will eventually affect the moisture absorption and quick drying effect of the fabric
Moreover, after the fabric absorbs moisture, the moisture will concentrate and diffuse along the arrangement direction of the hydrophilic yarn. Generally, the horizontal diffusion is fast and the vertical diffusion is slow, which is not conducive to forming a circle with the largest diffusion area and affecting the evaporation effect.
In addition, hydrophilic yarns and water-repellent yarns are difficult to identify by color alone, and they are easily confused during the weaving process, which will bring hidden dangers to the quick-drying effect of the final finished fabric
[0005] The existing method has brought a lot of inconvenience in production, and the moisture absorption and quick drying effect of the product needs to be improved

preparation example Construction

[0049] In a specific embodiment of the present invention, a method for preparing a moisture-absorbing quick-drying knitted fabric is provided, and the method for preparing the moisture-absorbing knitted fabric comprises the following steps:

[0050] Weft knitting the Siro composite yarn to obtain a knitted fabric;

[0051] Finish the knitted fabric to obtain a moisture-absorbing and quick-drying knitted fabric;

[0052] Among them, the Siro composite yarn is obtained by spinning the hydrophilic fiber and the water-repellent fiber separately into roving, and then blending the hydrophilic roving and the water-repellent roving.

[0053] In the fabric obtained through the above steps, the hydrophilic points and water-repellent points can be evenly distributed, so that sweat can be absorbed by the fabric and evaporated quickly. At the same time, the siro composite yarn reduces the moisture absorption rate of the fabric, thereby improving the drying speed of the fabric after absorb...

Embodiment 1

[0098] This embodiment provides a kind of 30s / l pure cotton moisture-absorbing quick-drying plain weave cloth (160g / m 2 ), which is prepared by the following steps:

[0099] Step 1: Preparation of 30s / 1 siro composite yarn:

[0100] Cotton (cotton 1) scouring→bleaching→dyeing→soaping, color fixing→hydrophilic soft oil→drying

[0101] Cotton (cotton 2) scouring→bleaching→dyeing→soaping, color fixing→over fluorine-containing water repellent→drying

[0102] The above-mentioned cotton 1 and cotton 2 are blended into 30S single yarn through a siro spinning frame.

[0103] Wherein cotton 1, the scouring of cotton fiber, bleaching, dyeing, soaping, color fixation all carry out according to conventional cotton dyeing process, after the color fixation is finished, cotton is added concentration and is 20g / L hydrophilic soft oil A-100 (Delong Company) in the aqueous solution, 45 ℃ for 25 minutes, the bath ratio is 1:10. The treated yarn is dried by high frequency at 85°C.

Embodiment 2

[0111] This example provides a 20s / 1 pure cotton moisture-absorbing and quick-drying piqué, which is prepared through the following steps:

[0112] Step 1: Preparation of 20s / 1 siro composite yarn:

[0113] Cotton (cotton 1) scouring→bleaching→dyeing→soaping, color fixing→hydrophilic soft oil→drying

[0114] Cotton (cotton 2) scouring→bleaching→dyeing→soaping, color fixing→passing fluorine-free water repellent→drying

[0115] The above-mentioned cotton 1 and cotton 2 are blended into 20s / 1 single yarn through a siro spinning frame.

[0116] Among them, the scouring, bleaching, dyeing, soaping, and color fixing of cotton 1 are all carried out according to the conventional cotton dyeing process. After the color fixing is completed, the cotton is added with a concentration of 20g / L hydrophilic soft oil S-3171 (Dyeing Online Company ) in an aqueous solution at 40°C for 20 minutes with a bath ratio of 1:15. The treated yarn is dried by high frequency at 85°C.

Abstract

The invention provides a quick-dry moisture-absorption knitted fabric and a preparation method thereof. The preparation method comprises the steps that composite Siro yarns are subjected to weft knitting to obtain a knitted fabric; the knitted fabric is subjected to after-finish to obtain the quick-dry moisture-absorption knitted fabric, wherein the composite Siro yarns are prepared in a mode thathydrophilic fibers and water-repellency fibers are singly spun into thick yarns respectively, and then the hydrophilic thick yarns and the water-repellency thick yarns are subjected to blending and knitting. The invention further provides the knitted fabric prepared by the preparation method. The knitted fabric has a good quick-dry moisture-absorption function.

Description

technical field [0001] The invention relates to a method for preparing a knitted fabric, in particular to a method for preparing a moisture-absorbing and quick-drying knitted fabric, which belongs to the technical field of textile printing and dyeing. Background technique [0002] Natural fibers come from the natural environment, especially cotton fibers, which are naturally skin-friendly, environmentally friendly and biodegradable, and are favored by consumers. Cotton fiber has excellent hygroscopicity and can absorb more than 2 times its own weight in water. In the process of wearing and using, if consumers wear pure cotton clothing, although they can quickly absorb sweat, the fabric will become heavy after sweating, and the sweat evaporates slowly, which greatly affects the wearing comfort. [0003] In order to overcome the existing problems of weight gain, slow evaporation, and slow drying of pure cotton fibers after absorbing moisture, the usual practice in the industr...
