Description

Technical Field

[0001] The invention relates to the technical field of knitted fabrics, and in particular to a light sports functional fabric containing wool jacquard texture and a preparation method thereof. Background Art

[0002] The wool products commonly used in the current market are mostly sweater products, which are not suitable for sports wear. Some knitted products have the itchy feeling of wool and are not suitable for close-fitting wear. Wool is a very good hydrophilic fiber, and its hygroscopicity is better than that of conventional synthetic fibers and natural fibers such as cotton and mulberry silk. It is dry and not sticky when worn during exercise, and is a good sports companion. However, as a kind of heavy, warm and hygroscopic fiber, wool is inconvenient to wash and care for clothes woven from wool, and it is easy to pill and deform. At the same time, it has poor quick-drying property, and it is inevitable that a feeling of stuffiness will occur when applied to sportswear. Therefore, the present invention obtains a light sports functional fabric containing a wool jacquard texture through a specific weaving process and a dyeing and finishing process. The fabric is light in weight, not easy to pill and deform, absorbs moisture and dries quickly, and has a cool and antibacterial function and a dry and comfortable wearing experience, and has good market prospects and application value.

[0024] Furthermore, in step 5, acid dyes and auxiliaries are used to dye nylon filaments and modal fibers at a dyeing temperature of 30-100° C. for 40-90 minutes.

[0025] Specifically, in step 5, the fabric is placed in a dye vat at 20-40°C, and a leveling agent, acetic acid and a defoaming agent are added in sequence, wherein the bath ratio of the leveling agent and the defoaming agent is 1:6-10, and the pH in the dye vat is adjusted to 3.5-5.5 by an acetic acid aqueous solution, and then an acid dye with a mass fraction of 1.5%-2% is added, and then the temperature is raised to 60-80°C for dyeing for 8-12 minutes, and then the temperature is further raised to 90-110°C for dyeing for 25-35 minutes, and then the temperature is lowered to 50-65°C for washing. Wherein, the acid dye is an anthraquinone acid dye.

[0026] Furthermore, in step 5, the ultrafine wool is dyed with reactive dyes at a temperature of 30-80° C. for 90-120 min.

[0028] Furthermore, the color fixing agent is a color fixing agent that does not contain bisphenol.

[0029] Furthermore, a softening step is provided between step S5 and step S6, and the softening step is specifically as follows: after dyeing, a softening agent is added into the vat for softening, the bath ratio is 1:9-11, the softening temperature is 50-60°C, and the softening time is 15-25min. The elasticity of the fabric is improved, the fabric has good hydrophilicity, and the hand feel is plump.

[0030] Furthermore, the softening aid is a softening aid of fatty acid and polyol compound type.

[0031] Furthermore, in step S6, the finished product is processed by adding 1-3kg / L of silicone oil and 10-14kg / L of soft oil in a setting machine for surface treatment, and then drying at 150-180°C, with the speed of the setting machine being 28-32m / min; so that the fabric has a comfortable and soft feel.

[0032] Further, in step S7, the heavy pressure leveling treatment is performed by leveling with a heavy pressure roller of a shrinking machine, the pressure of the pressure roller of the shrinking machine is set to 3-5 Bar, and the heavy pressure leveling is used to improve the flatness of the fabric and the texture of the fabric.

[0033] The invention adopts a two-bath dyeing process to effectively avoid mutual interference between two dyes, so that the fabric can achieve the best dyeing rate and color fastness. The color fixation treatment can improve the soaping fastness of the fabric and reduce the fading of the fabric.

[0034] The beneficial effects of the present invention are as follows: the present invention weaves a light sports functional fabric with jacquard texture by blending yarn and nylon filament, so that the fabric has light weight and exquisite jacquard appearance; wherein the blended yarn is a high-count yarn of 60S or more blended by ultrafine wool and ultrafine modal fiber, so that the fabric has a delicate and comfortable hand feel, and at the same time, 1.5% nano-level ice jade ultrafine mineral powder is added to the nylon filament, so that the fabric has a cool feeling and antibacterial function; before dyeing, a bioenzyme polishing treatment is added to make the fabric smooth and have a strong texture. The wool and nylon are dyed in two baths, and the color fixing process without bisphenol and soft finishing are matched to increase the comfort of the fabric and the color washability, so that the fabric has the effects of lasting cold feeling, no pilling, not easy to fade and quick drying in washing water on the basis of maintaining the advantages of the wool fiber itself, thereby realizing the light sports functional fabric with wool jacquard texture that integrates contact coolness, anti-pilling, high soaping fastness, and moisture absorption and quick drying.
