Embodiment 1
[0033] A preparation method for a composite size used for sizing high-count pure cotton yarns, comprising the following steps:
[0034] (1) Add the dried beer grains into water, the bath ratio is 1:5, wash 4 times, filter with a 50-mesh sieve, and filter out the remaining soluble sugar in the beer grains, which is beneficial to the improvement of the serous film performance;
[0035] (2) place the brewer's grains after desugaring outside, and carry out natural drying;
[0036] (3) Adopting a universal pulverizer to pulverize the dried distiller's grains into 50 mesh powders;
[0037] (4) Sodium hydroxide solution is used to extract the protein soluble matter in the pulverized beer dried distiller's grains powder, the ratio of sugar-removed beer dried distiller's grains to water is 1:6, the alkali concentration is 1%, and the heating temperature is 50°C. The heating time is 30min;
[0038] (5) Adopt high-speed centrifuge to carry out solid-liquid separation to the prepared br...
Embodiment 2
[0051] A method for preparing composite size for high-count pure cotton yarn sizing, comprising the following steps:
[0052] (1) Add the dried beer grains into water with a liquor ratio of 1:30, wash once, filter with a 100-mesh sieve, and filter out the remaining soluble sugar in the beer grains, which is beneficial to the improvement of the serous film performance;
[0053] (2) put the brewer's grains after desugaring into a blast oven for drying, and the temperature can be 50°C;
[0054] (3) Adopting a universal pulverizer to pulverize the dried distiller's grains into 50 mesh powders;
[0055] (4) Alkaline solution is used to extract the protein soluble substances in the pulverized beer dried distiller's grains powder, the ratio of sugar-free beer dried distiller's grains to water is 1:10, the alkali concentration is 1.5%, the heating temperature is 90°C, and the heating time is 60min;
[0056] (5) Adopt high-speed centrifuge to carry out solid-liquid separation to the pr...

Abstract
The invention relates to preparation and application of a composite sizing agent for high-count cotton yarn sizing and a desizing method. The preparation and application comprise the following steps: (1) using brewer's grains as a raw material for preparation of the composite sizing agent, putting the above materials into a sodium hydroxide solution, heating at constant temperature of 50-90 DEG C for 30-90 min, centrifuging or carrying out suction filtration to remove undissolved residue, and using a supernatant to prepare the composite sizing agent for high-count cotton yarn sizing; and (2) carrying out sizing process of cotton yarn by the use of a single-yarn sizing machine, adopting a double soak and press mode with temperature of sizing box being 40-70 DEG C, dying room temperature being 50-80 DEG C and sizing speed being 10-50 m / min, controlling permeation and coating ratio of the size in the yarn according to pressure adjustment, and carrying out coordination control of sizing percentage by sizing agent concentration and pressure. The prepared composite sizing agent is low-cost, has good sizing performance, is suitable for cotton yarn sizing, is easy to desize, contains no hardly degradable substance or substances harmful to the environment, and is clean and environmentally friendly.
Description
technical field [0001] The invention relates to the preparation, application and desizing method of a novel composite size suitable for sizing high-count pure cotton yarns. Background technique [0002] The purpose of sizing is to saturate and cover the yarn with sizing material to increase its strength, improve wear resistance, and reduce hairiness, thereby reducing or preventing warp yarn breakage in the weaving process and improving weaving efficiency. It is a must in the textile industry. An indispensable process. At present, the three main varieties in the size industry are: polyvinyl alcohol, modified starch and acrylic size. Starch size has good film-forming properties, strong affinity with natural fibers, and is easy to desizing; but starch size has insufficient sizing strength, is easy to break, and has poor wear resistance. Polyvinyl alcohol sizing film has high strength and good flexibility, and is often used for sizing pure cotton. However, it is difficult to d...
