A kind of textile size composition and preparation method thereof

Abstract

The invention discloses a textile size composition and a preparation method thereof, belonging to the technical field of sizing. The composition is made of the following raw materials in parts by weight: 45-60 parts of carbamate modified starch, 2-5 parts of sodium alginate, 35-45 parts of PVA, 10-15 parts of LMA slurry, 2-5 parts of sodium silicate 1-4 parts, 1-4 parts of emulsified oil, 3-5 parts of smoothing agent, 1-4 parts of soaking agent and water, and the water adjusts the solid content of the composition to 12-14.5%. The composition is mainly aimed at pure cotton fabrics. From the perspective of the size itself, the viscosity of the size tank is 7.5-8.5s, the viscosity thermal stability is 94-97%, and the viscosity and thermal stability are relatively good; from the quality of the fabric Said that its sizing rate is slightly increased, the reinforcement rate and good axis rate are greatly improved, and the elongation rate is slightly decreased; from the perspective of textile efficiency, the speed and efficiency of the textile have a certain increase; from the cost point of view, the use of more expensive raw materials, but the overall cost has not increased.

Description

technical field [0001] The present invention relates to the technical field of sizing, in particular to a textile size composition and a preparation method thereof, in particular to a size composition for pure cotton fabrics, such as for CJ 14.5 / 14.5 523.5 / 393 238.5 and CJ / C 14.5 / 14.5 523.5 / 393.5 170 and other pure cotton fabrics. Background technique [0002] Sizing is the process of applying size to warp yarns to improve their weavability. Weavability refers to the performance of warp yarns that can withstand repeated friction, stretching, bending, etc. of warp stoppers, healds, reeds, etc. on the loom without fluffing or even breaking. Unsized single yarn fibers do not cohere firmly with each other, and the surface has more hairiness, making it difficult to weave. After sizing, part of the size penetrates between the fibers, and the other part adheres to the warp surface. The sizing mainly in which the size penetrates between the fibers is called penetrating sizing, a...

Problems solved by technology

[0005] However, for pure cotton fabrics, it is found that when sizing with conventional modified starch and PVA-based sizing supplemented with LMA-95 or LMA-96, "sticking, twisting, and broken ends" are relatively difficult during sizing. There are many pulp stains and defects in the cloth, and there are a small number of machines that accumulate fly at the menopause sheet during weaving

Warp breakage increases, loom efficiency hovers at 80% for a long time, resulting in high pulp consumption rate and higher cost in disguise
