Embodiment 1
[0016] Put 85kg of cornstarch, 3kg of ethylene oxide, 6kg of sodium hexametaphosphate, 4kg of polyvinylpyrrolidone, and 2kg of calcium persulfate into the reaction tank respectively, and carry out the compound mixing reaction at 63°C for 1.0h to terminate the reaction, unload Material packaging, storage. When the customer is using it, add 887kg of clear water to gelatinize and heat up to 95°C or add clean water to a high-pressure tank and heat up to 125°C for 30-50 minutes to carry out etherification, cross-linking, and oxidation compound reactions to obtain an emulsion for sizing fabrics.
[0017] Its biodegradation test grade 9. After the slurry adhesion test, the pure cotton adhesion is 106N, and the polyester-cotton adhesion is 144N. Carry out the same adhesion test to the slurry prepared in Example 1 in CN102733190A, CN102733191A, and CN102605618A respectively, wherein CN102733190A pure cotton adhesion is 91N, polyester cotton adhesion is 115N; CN102733191A pure cotton a...
Embodiment 2
[0020] Put 88kg of cornstarch, 2kg of ethylene oxide, 5kg of sodium hexametaphosphate, 3kg of polyvinylpyrrolidone, and 2kg of potassium hydrogen persulfate into the reaction tank respectively, and carry out the compound mixing reaction at 63°C for 1.0h before terminating the reaction , unloading packaging, storage. When the customer is using it, add 881kg of clear water to gelatinize and raise the temperature to 95°C or add clear water to a high-pressure tank and raise the temperature to 125°C for 30-50 minutes to carry out etherification, cross-linking, and oxidation compound reactions to obtain a fabric sizing emulsion. After the slurry adhesion test, the pure cotton adhesion is 102N, and the polyester-cotton adhesion is 138N. The toughness and wear resistance tests were carried out on the serous film obtained by compounding this product with the auxiliary material of test 1, and the wear resistance was 1.96mg / cm 2 .
