The invention relates to a preparation method of a textile size applicable to high-count cotton fabrics. The preparation method comprises the steps of: mixing hydroxypropyl modified starch with silicon powder, adding into deionized water, adding sodium hydroxide and methyl alcohol, and carrying out drying and purification after hydrolysis to obtain nano silicon dioxide modified starch; adding soybean protein in sodium hydroxide solution, stirring at a constant speed at 40 DEG C for 15 minutes, and filtering out the precipitates to obtain protein size; pouring the nano silicon dioxide modified starch, the protein size, polyacrylate emulsion and modified silicon oil defoaming agent in a stirrer for stirring and mixing to obtain the textile size applicable to high-count cotton fabrics. The size prepared by the method has favorable film forming property and permeability, is particularly applicable to the sizing of high-count cotton fabrics as the sizing property is excellent, and is more environment-friendly as the formula does not contain polyvinyl alcohol.

The invention relates to flour for frozen instant noodles, flour cakes and frozen instant noodles prepared by the flour. The flour for frozen instant noodles comprises raw materials in parts by weight as follows: 45-55 parts of wheatmeal and 5-10 parts of starch acetate or cassava starch. The wheatmeal used in the flour provided by the invention is high quality wheatmeal which is from a ''golden wheat field'', and green and natural with pure flavor. The starch acetate is used as a thickener in food, wherein the starch acetate is high in viscosity, high in clarity, weak in retrogradation, stable to store, high stability to acids, alkalis and heat, low in gelatinization temperature, and good in film formation, so that the product has a clean and smooth surface and good freeze-thaw stability, and hydrogen bonds are not easy to form among molecules. The frozen instant noodles prepared by the flour for frozen instant noodles provided by the invention not only have fast food property of instant noodles, but also have the advantages of health and nutrition and high quality compared with fried instant noodles.

The invention relates to textile size applicable to real silk fabrics. The textile size comprises the following components in mass ratio: 70 parts of protein size, 20 parts of nano silicon dioxide modified starch, 8 parts of polyacrylate emulsion, 2 parts of modified silicone oil defoaming agent, 6 parts of argine monohydrochloride, 3 parts of sodium sulfamate and 1 part of polyacrylate. According to the textile size applicable to real silk fabrics, the protein size is taken as a primary raw material, the nano silicon dioxide modified starch and the polyacrylate emulsion are taken as secondary raw materials, the modified silicone oil is taken as a defoaming agent, and the four components are proportioned, so that the size has favorable film forming property and permeability; experiments show that the textile size is particularly applicable to the sizing of the real silk fabrics; as the formula does not contain polyvinyl alcohol, the textile size is more environment-friendly.

The invention relates to a sizing method of textile slurry high-count cotton fabrics, which comprises the following steps: pouring slurry into a slurry trough, and heating the slurry in the slurry trough to 58 DEG C; immersing the fabric into the slurry in the slurry trough for 8 minutes while winding the fabric on a frame to tighten the fabric and rolling the fabric at uniform speed so that the slurry is sufficiently and uniformly filled into the fabric, wherein the pressure of the squeezing roller is 14KN; taking out the fabric, putting the fabric in a drying oven, and drying the fabric; immersing the dried fabric into the slurry again for 3 minutes, and rolling the fabric at uniform speed, wherein the pressure of the squeezing roller is 16KN; and taking out the fabric, putting the fabric in a drying oven, and drying the fabric to finish the sizing technique. The method completes the fabric sizing in a twice sizing mode, and designs the technological parameters (mainly temperature of the slurry trough, immersion time for two sizing processes, and pressure of the squeezing roller) according to the specific slurry. The sizing technique is especially suitable for sizing high-count cotton fabrics, and has favorable sizing effect.

The invention relates to a sizing method of environment-friendly textile slurry, which comprises the following steps: pouring slurry into a slurry trough, and heating the slurry in the slurry trough to 55 DEG C; immersing the fabric into the slurry in the slurry trough for 5 minutes while winding the fabric on a frame to tighten the fabric and rolling the fabric at uniform speed so that the slurry is sufficiently and uniformly filled into the fabric, wherein the pressure of the squeezing roller is 13KN; taking out the fabric, putting the fabric in a drying oven, and drying the fabric; immersing the dried fabric into the slurry again for 2 minutes, and rolling the fabric at uniform speed, wherein the pressure of the squeezing roller is 15KN; and taking out the fabric, putting the fabric in a drying oven, and drying the fabric to finish the sizing technique. The method completes the fabric sizing in a twice sizing mode, and designs the technological parameters (mainly temperature of the slurry trough, immersion time for two sizing processes, and pressure of the squeezing roller) according to the specific slurry.
