Problems solved by technology

[0004] First of all, in the existing weaving process, because the kapok fiber is short, light, slippery and rigid, it is easy to suspend and fly. Concentrating on the reed will cause problems of flocculation or yarn breakage, resulting in lower grades of kapok blended fabrics, which are difficult to meet customer requirements
[0005] Secondly, different from other yarns, kapok blended yarn is relatively fluffy. If weaving according to the existing specification design method (yarn count, warp and weft density, weight per square meter), fabrics of the same thickness often appear, and their weight does not match. , or fabrics of the same gram weight, their yarn counts and densities do not match; often after weaving, it is found that the obtained kapok blended fabric is too saturated, the fabric appears hardened, and has a paper-like feel, losing the fluffy and soft style characteristics of kapok blended fabric , repeated weaving, it is difficult to obtain a kapok blended fabric that meets the requirements and feels fluffy and soft
[0006] Using the existing cotton blended fabric weaving method, although it can be woven, the resulting kapok blended fabric has a high defective rate, poor hand feeling, and is difficult to meet the demand requirements, which affects sales and brings greater economic losses to the enterprise.

Abstract

The invention discloses a method for weaving kapok blended fabrics and belongs to the technical field of weaving of kapok blended fabrics. The method is characterized by comprising the following steps: respectively beaming warp yarns and weft yarns, wherein the mass of kapok fibers in kapok blended yarns account for 10-70%; slashing, namely respectively immersing the beamed warp yarns and weft yarns into a sizing agent for slashing, wherein the sizing agent used in slashing comprises 72-77g / L of starch, 8.7-10.8g / L of acrylic acid, 23-27g / L of polyvinyl alcohol, 1.8-2.3g / L of urea, 8-12g / L of glycerin and water serving as a solvent; and weaving, namely weaving the warp yarns and weft yarns subjected to slashing, thereby obtaining the kapok blended fabrics. According to the method for weaving kapok blended fabrics, disclosed by the invention, the sizing agent with specific components is given for slashing, so that the problems of knotting and breaking of the kapok blended yarns during weaving can be well solved.

Description

technical field [0001] The invention relates to a weaving method of kapok blended fabric, which belongs to the weaving technical field of kapok blended woven fabric. Background technique [0002] Kapok fiber has the properties of high hollowness, good warmth retention, softness, and smoothness. Kapok fiber is the fruit fiber of several plants in the Malvaceae Kapok family. It is a single-cell fiber. Cells develop and grow. Generally, it is about 8~32mm long and 20~45μm in diameter. It is the thinnest, lightest, highest hollow and warmest fiber material among natural ecological fibers. Its fineness is only 1 / 2 of cotton fiber, but the hollow rate is over 86%, which is 2~3 times that of ordinary cotton fiber. It has the characteristics of smooth, antibacterial, moth-proof, mildew-proof, soft, not easy to tangle, impermeable, non-heat-conducting, ecological, warm, and strong hygroscopicity. Kapok fiber is blended with cotton, hemp, and viscose to form kapok blended yarn, wh...
