Embodiment 1
[0020] Slurry formula: 80% modified starch, 15% hydroxyethyl cellulose, 5% chitosan.
[0021] The preparation method of modified starch: first put 100 kg corn starch and 200 kg water into the reaction kettle, heat and stir to dissolve, when the temperature reaches the gelatinization temperature, then add 0.25 kg orthosilicic acid and 0.25 kg amber in three batches Anhydride, stir for 1 hour after adding orthosilicic acid and succinic anhydride each time, when the orthosilicic acid and succinic anhydride are added, add 0.1 kg of silica sol with a silica content of 31%, keep warm for a period of time, cool, and use a small amount of The sodium hydroxide solution was used to adjust the pH value to 7, and finally the modified starch was obtained by spray drying.
[0022] Textile size compounding: Fully mix in a vacuum kneader according to the weight ratio of 80% of modified starch, 15% of hydroxyethyl cellulose, and 5% of chitosan to obtain textile size, and package the finished p...
Embodiment 2
[0024] Modified starch 95%, sodium carboxymethyl cellulose 1%, gelatin 4%.
[0025] The preparation method of modified starch: first put 100 kg of wheat starch and 200 kg of water into the reaction kettle, heat and stir to dissolve, when the temperature reaches the gelatinization temperature, then add 1 kg of metasilicate and 4 kg of horse starch in four batches For maleic anhydride, stir for 1 hour after adding metasilicic acid and maleic anhydride each time. After adding metasilicic acid and maleic anhydride, add 0.5 kg of silica sol with a silica content of 15%, keep warm for a period of time, and then cool , adjust the pH value to 7 with a small amount of potassium hydroxide solution, and finally obtain the modified starch through spray drying.
[0026] Textile pulp compounding: Fully mix in a vacuum kneader according to the weight ratio of 95% modified starch, 1% sodium carboxymethyl cellulose, and 4% gelatin to obtain textile pulp, and package the finished product.
Embodiment 3
[0028] Modified starch 85%, hydroxyethyl cellulose 10%, gum arabic 5%.
[0029] The preparation method of modified starch: first put 100 kg tapioca starch and 200 kg water into the reaction kettle, heat and stir to dissolve, when the temperature reaches the gelatinization temperature, then add 1 kg disilicate and 2 kg grass anhydride, add disilicate and oxalic anhydride each time and stir for 1 hour, when disilicate and oxalic anhydride are added, then add 0.3 kg of silica sol with a silica content of 20%, keep warm for a period of time, cool, and use a small amount of The potassium hydroxide solution was used to adjust the pH to 7, and finally the modified starch was obtained by spray drying.
[0030] Textile size compounding: Fully mix in a vacuum kneader according to the weight ratio of 85% of modified starch, 10% of hydroxyethyl cellulose, and 5% of gum arabic, to obtain textile size, and package the finished product.
