Stepwise yarn sizing pulp and sizing method

Abstract

The invention belongs to the technical field of textile sizing, and particularly relates to stepwise yarn sizing pulp and sizing method. The stepwise yarn sizing pulp is composed of inner soakage pulpand outer coating pulp, wherein the inner soakage pulp is a mixture of starch, propylene and water, and the outer coating pulp is a mixture of polyvinyl alcohol and the water. According to the stepwise yarn sizing method, the sizing method is simple, industrial production is easy to realize, the production cost is greatly reduced, and on the premise of reducing excess sizing, the strength increase rate, the hairiness reduction rate, the wear resistance improvement rate and the weaving efficiency are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of textile sizing, and in particular relates to a step-by-step sizing material for yarns and a sizing method thereof. Background technique [0002] At present, the known sizing method is to perform one sizing and one drying, because the sizing of the yarn can increase the strength of the yarn when the sizing is soaked, and better sizing penetration requires low-viscosity sizing and high-pressure sizing, and the coating of the sizing can To increase the wear resistance of yarn, better size coating requires high concentration of size and low pressure. In order to ensure the strength and wear resistance of the yarn at the same time, this sizing method has a greater improvement rate. The increase rate of wear resistance is compromised, and the strength and wear resistance of the yarn cannot be achieved at the same time. [0003] In order to improve the strength and wear resistance of yarn, domestic scholars hav...

Problems solved by technology

The above method can only focus on improving the single performance of the yarn according to the needs, and cannot achieve the best warp strength and wear resistance. At the same time, in order to ensure that the warp yarn after sizing can have the best weavable performance They are all realized by using a higher warp sizing rate, which increases the cost of sizing while having a negative impact on the hand feel of the textile, and a higher warp sizing rate is not conducive to the green environmental protection requirements in the finishing and desizing process

[0004] Compared with foreign sizing technologies, "Study of Novel Pregelled Starch for Sizing of Cotton Textiles" published in "Research Journal of Textile and Apparel" and "Functions of soybean compositions intextile sizing" published in "Industrial Crops & Products" focused on used to study new types of slurry, but the slurry used in this method is expensive and cannot be used industrially
