Self-cleaning size for yarns, self-cleaning yarn and preparation method thereof

Abstract

The invention relates to a self-cleaning size for yarns, a self-cleaning yarn and a preparation method thereof. The self-cleaning size for yarns is prepared from the following components in parts by weight: 40 to 60 parts of starch, 25 to 45 parts of polyvinyl alcohol, 1 to 6 parts of biological enzyme, 1 to 10 parts of nano-nickel oxide, 1 to 8 parts of Na-montmorillonite, 1 to 8 parts of metal naphthenate, 3 to 15 parts of organic alcohol, 1 to 8 parts of coupling agent, 1 to 8 parts of cross-linking agent, 1 to 8 parts of dispersant and 100 to 150 parts of water. The self-cleaning size for yarns disclosed by the invention can ensure that highly complex multiple nanoscale and micron-scale ultramicrostructures are formed on the surface of a yarn, consequently, a lotus effect is generated, and the yarn obtains a self-cleaning characteristic like a lotus leaf; moreover, under the effect of light, the self-cleaning size for yarns can generate a strong catalytic degradation function, consequently, odor can be effectively removed, staining can be effectively resisted, a variety of bacteria and fungi can be killed, and the yarn cannot be easily stained, and is easy to clean. The size has good adhesion to the yarn, the polyvinyl alcohol is highly compatible to the starch, furthermore, the flexibility of a size film can be enhanced, and the mechanical property of the yarn can be increased.

Description

technical field [0001] The invention relates to the field of yarn processing, in particular to a yarn self-cleaning slurry, a self-cleaning yarn and a preparation method thereof. Background technique [0002] Yarn is a soft and slender fiber aggregate with certain mechanical properties formed by the aggregation of textile fibers along the length direction. According to the structure and shape, it includes filament yarn, spun yarn and special yarn. According to the types of fibers that make up the yarn, it includes pure spinning yarn, blended yarn, polyester / cotton yarn (T / C yarn), CVC yarn, etc. At present, the yarn is treated with sizing to increase its strength, that is, yarn sizing is a key link in the weaving process. The purpose of sizing is mainly to improve the wear resistance of the yarn, reduce hairiness, and appropriately increase the strength of the yarn. Reduce the elongation to withstand the mechanical force on the warp yarn during the weaving process and impr...
