The invention discloses a textile sizing agent for PVA-free and low-sizing rate sizing of pure cotton fabric warps, and belongs to the field of textiles. Through combination of microbial polysaccharide xanthan gum, gellan gum and curdlan which are biotechnologically developed and starch, the pure cotton warps are sized. 5-20wt% of starch and 80-95wt% of an auxiliary agent, comprising 30-50wt% of xanthan gum, 20-30wt% of gellan gum, 20-40wt% of curdlan and 3-10wt% of emulsified oil, are proportionally mixed for sizing 40-60-count pure cotton warps, so that PVA-free and low-sizing rate sizing can be achieved, the sizing rate can be reduced from the conventional 12-14% to 6-7%, and the sizing agent resource can be significantly saved; in addition, when the textile sizing agent is used for sizing, few cotton and few sizing agent drop, opening is clear, the weaving efficiency can reach 91% or above, and the desizing grade is up to 9.

The invention relates to YDM-J type organic compound slurry for the flax spinning industry, as well as a preparation method thereof. The slurry is characterized by comprising the following components in percentage by weight: 2-4 percent of oxidative high-carbon alkyl dimethyl amine, 1-2 percent of diethylene triamine, 2-4 percent of alcamines, 1-3 percent of polyoxyethylene ether type emulsifier,2-4 percent of oleic acid, 1-2 percent of organic solvent, 2-4 percent of penetrating agent, 3-5 percent of carboxymethyl cellulose and 72-86 percent of water. The preparation method comprises the following steps that: firstly: the components are added to a reaction kettle according to mixture ratio, wherein the water with the weight half of the mixture weight is added; secondly, the carboxymethyl cellulose, a semi-finished product of a first step and the penetrating agent are injected into the reaction kettle. A usage of the slurry comprises the following: A. a technique of finishing flax warp sizing in a small flume of a sectional warping machine; B. a technique of finishing flax warp sizing in a slurry tank of a sizing machine. The slurry forms a smooth, wear-resistant and flexile thinfilm on the surface of warp, which improves yarn strength, reduces rear-machine broken ends and improves loom efficiency.

The invention belongs to the technical field of novel chemical fiber materials, and specifically relates to modified polyester slurry and a preparation method thereof. The modified polyester slurry comprises 5 to 100 parts of modifier, 1 to 20 parts of polyester, 0.05 to 0.1 part of modified montmorillonite and 50 to 200 parts of water by weight. The modifier is prepared from hydrated silica and silicone oil, and the polyester is prepared from 30 to 55 parts by weight of citric acid, 15 to 26 parts by weight of PEG-200, 15 to 40 parts by weight of 2,2-bis (hydroxymethyl) propionic acid, 5 to 10 parts by weight of glycerin, and 1 to 10 parts by weight of pure water; and the modified montmorillonite is prepared from 50 to 100 parts by weight of montmorillonite and 30 to 50 parts by weight ofsilicone oil. According to the modified polyester slurry prepared by the invention, the viscosity and the surface tension of the slurry can be reduced by adding the modifier, so that the slurry permeability is improved; and by adding the modified montmorillonite, the tensile property of a yarn is improved, the end breakage rate is reduced, the cost is reduced, the degradation is easy, the operation is convenient, the pollution is avoided, no catalyst is needed in the preparation of the polyester, and the modified polyester slurry has higher economic benefits and social benefits.

The invention discloses emulsion paraffin for textile. The emulsion paraffin is prepared by following raw materials in parts by weight: 100 to 120 parts of paraffin, 10 to 15 parts of calcium stearate, 3 to 6 parts of carboxymethylcellulose, 3 to 6 parts of stearic acid monoglycerides, 6 to 12 parts of sorbitol mono-olein, 2 to 5 parts of Vaseline, 3 to 6 parts of crylic acid, 20 to 40 parts of ethanol, 0.5 to 1.5 parts of triethylhexyl phosphate, 12 to 15 parts of an emulsifier and 180 to 200 parts of water, wherein the emulsifier is a mixture of sodium dodecyl sulfate, Arabic gum, sodium caseinate and polyacrylamide. The emulsion paraffin is suitable for various fiber fabrics such as chemical fibers, blended fabric, silk, pure cotton and hemp, the weaving friction coefficient can be effectively reduced, the weaving end broken rate is reduced, the opening of the fabric is clear, the first-grade ratio of the cloth can be increased, and the efficiency of a weaving machine can be greatly improved; moreover, the emulsion paraffin is easy in desizing, suitable for printing and little in consumption, and the cost can be reduced by 10 to 12 Yuan for each bolt of cloth.

The invention discloses a manufacture technique of a siro yarn jean fabric, in which, firstly an advanced siro yarn spinning technology is adopted to manufacture the siro yarn; the spun siro yarn is wound; then the wound siro yarn which is used as a warp is warped, dyed and starched be manufactured into a beam; then the siro yarn is used as the warp and the siro yarn, a rotor spun yarn or a ring yarn are used as an abb to be woven on a loom according to the fabric weave and the weaving technique of the jean to manufacture a grey fabric and finally the grey fabric is made into a finished product through subsequent finishing. As the siro yarn with better quality is adopted as the warp, the method has the advantages of easy yarn splitting, few broken ends, uniform colorizing, reducible sizing quality requirement as well as high heddle draft and reeding efficiency during the dyeing process, clear cut, uniform tension, few broken ends and stopping, few fly wastes in a workshop and on a machine station as well as being beneficial to the cleanness of the workshop and the maintenance of the machine station when weaving.
