Description

Weaving method of moisture-absorbing heating antibacterial fabric
Technical Field
The invention belongs to the field of fabric weaving, and particularly relates to a fabric weaving method.
Background
The cold-proof and warm-keeping are important indexes of the comfort of the clothes in autumn and winter, and the traditional warm-keeping clothes are too bulky, are not convenient to move and lack of aesthetic feeling. For example, patent application 201410052915.7 discloses a moisture-absorbing, heating, quick-drying, moisturizing and warm-keeping fabric and a preparation method thereof, and the fabric obtained by the invention cannot be made very thin and is slightly bulky on the premise of ensuring the comfort and elasticity of the fabric, so that the requirements of light weight, thinness and warm keeping of people are difficult to meet. Nowadays, people have higher and higher requirements on the comfort, functionality and aesthetic property of clothes, so that the moisture-absorbing and heat-emitting fabric is popular with the public.
At present, in order to improve the performance of the moisture-absorbing and heat-generating fabric, the fiber in the fabric is usually treated, and the following methods are mainly used:
1. the fiber is subjected to high-hydrophilization treatment, hydrophilic groups such as amino, carboxyl and the like are introduced into a molecular chain, and crosslinking treatment is carried out to obtain the fiber with strong moisture absorption performance, but the fabric obtained by the method is not resistant to soaping, the washing performance is attenuated by using the fabric, and the moisture absorption and heat generation performance is not stable as compared with kapok fiber;
2. the specific surface area of the fiber is increased by increasing cracks, micropores and the like of the fiber, so that the surface energy is increased, and the moisture absorption is improved;
3. the yarns spun by combining the cellulose fibers and the synthetic fibers have high hygroscopicity and capillary effect, and can quickly absorb sweat and diffuse the sweat;
4. a substance is added to the interior of the fiber or coated on the surface of the fiber, and after absorbing moisture, the substance undergoes a chemical reaction and releases heat.
However, the method increases energy consumption, increases the emission of carbon and other pollutants, easily causes pollution to the environment, and easily causes the pollutants to remain on the fabric, which is not beneficial to human bodies.
The moisture absorption and heat generation type alkali-free mercerized fabric and the processing method thereof are disclosed in a patent (with an authorization publication number of CN102877196B), the moisture absorption and heat generation functions are realized because the inner layer and the middle layer of the fabric are made of moisture absorption and heat generation raw materials, namely, heat absorption and heat generation yarns, which are novel raw materials obtained by specially processing polyester fibers and viscose, and the raw materials have the moisture absorption and heat generation functions; however, the inner layer of the moisture-absorbing and heating knitted fabric contains a large number of polyester fibers, and although a special novel spinning technology is adopted, the obtained fabric is easy to fluff and pill, the fluff and pill resistance performance is poor, and the appearance of ready-made clothes can be influenced after long-time dressing.
Because the kapok fiber is a green and environment-friendly natural fiber, has the characteristics of light weight, natural heat preservation, antibiosis, environment protection and the like, but has poor spinnability, is generally difficult to be spun purely, and can be blended with cotton or other cellulose fibers to produce clothing fabric with good luster and hand feeling. However, the following problems still remain: the kapok fiber has the advantages of high torsional rigidity, high filoplume during spinning, poor cohesion, low yarn strength and poor wear resistance, and is easy to damage the kapok fiber in the fabric due to friction during washing or wearing in the using process, so that the using effect of the kapok fiber is greatly reduced.
In addition, the average fineness of the comparison of the all-cotton fibers and the kapok fibers is as follows: all-cotton fiber 0.182tex, kapok fiber 0.1tex, and the cellulose center skeleton lacks in kapok fiber's cavity intracavity, still exists organic matter impurity such as: cottonseed hulls, fiber cuticle waxiness, pectin, ash and the like, wherein the existence of the waxiness and the pectin is a main influence factor for preventing the wettability of the fabric.
In the existing weaving method, a scouring process of dyeing and finishing is usually used for removing wax and pectin, but the existing scouring process has hydrolysis, emulsification and dissolution effects, and along with the prolonging of time and the increase of temperature, the embrittlement effect of caustic soda in a scouring agent on the kapok fiber is correspondingly increased, the excessive damage of cellulose on the cell wall in the fiber can be damaged, and the performance effect of moisture absorption and heat generation of the kapok fiber can be reduced.
