Embodiment 1

[0019] Yarn variety: Zhongchao Textile 968 of Zhonghua Spinning Mill, color: SG extra dark blue, yarn count 9.8S Zhonghua Slub, total yarn count 4400, total length 15300m, speed 25.8m / min.

[0020] The technological process is yarn cooking → multi-cylinder indigo dyeing and oxidation → multiple washings → sizing → drying → yarn separation → reel (finished product). Among them, in the multi-cylinder indigo dyeing and oxidation, two dipping and two padding methods are used for sizing, that is, dyeing and then padding, and then dyeing and padding again, repeating twice. Sizing temperature: 95°C, size tank volume 1100L.

[0021] The base slurry is 1100L. The raw materials include 135kg starch and 109.5kg multi-component copolymer rubber compound. In addition, it also includes 4KG wax oil, 6KG palmitic acid and water. The preparation method of the base slurry includes the following steps: the processing requires 1 / 2 of the water, adding Starch, multi-component copolymer rubber, wa...

Embodiment 2

[0027] With reference to Example 1, the difference is that the yarn color is blue-gray.

[0028] The technological process is yarn cooking→multi-cylinder dyeing and oxidation→multiple washing→sizing→drying→separating yarn→spool (finished product).

Abstract

The invention discloses denim flexible warp sizing slurry and method. The slurry comprises prime slurry and supplementary slurry; the prime slurry is prepared from raw materials of starch and a multi-component sizing material with a mass ratio of (1.2-1.3): 1, in addition, the prime slurry is further prepared from raw materials of wax oil, palmitic acid and water, wherein the mass ratio of the wax oil, the palmitic acid and the multi-component sizing material is (3-4): (4-6): 100, a sized yarn slurry film is smooth, complete, elastic, high in uniformity and good in abrasion performance, the slurry is stable in physical performance, has no skinning and layering and is stable viscosity, a yarn is endowed with good hairiness adhesion state, is easy to lease, and has special antistatic ability, the warp broken end is reduced, and the weaving efficiency is improved; and a denim fabric woven by the sized yarns is beautiful in color, good in glossiness, clean in cloth cover, soft in hand feeling and durable, and the drying procedure after yarn dyeing and water washing in the denim sizing and dyeing process is omitted, so that steam consumption for drying is saved.

Description

Technical field: [0001] The invention relates to a denim flexible warp sizing material and a sizing method. Background technique: [0002] The sizing process plays a key role in the denim production process. Warp sizing can enhance the strength of the yarn, reduce the friction of the yarn running, make the yarn pass through the brown eye and reed smoothly, make the opening easier, and reduce the weaving breakage. The head rate can be improved, thereby improving production efficiency and product quality, improving the gloss performance of the fabric surface, and maintaining the elasticity and elongation of the yarn; because sizing can make the yarn hairiness docile, it can improve the clarity of the fabric texture. CN 103966849 B discloses a warp sizing size for denim. The size is calculated in parts by weight and consists of 120 parts of DSC-14 starch, 10 parts of PVA, 25 parts of LMA-95 synthetic size, 16 parts of emulsified oil and The smoothing agent is prepared in 3 par...
