The water-based polyurethane finishing agent adopts a terminal polyurethane finishing agent, and is manufactured by China chemical industry Co., ltd;
example 1
Example 1 a method of anti-felting finishing of wool fabric comprises the steps of:
s1, preparing an acidic anti-felting finishing agent, uniformly mixing a polyurethane finishing agent, sodium alginate, a polybasic acid-pH regulator and water, then dropwise adding a calcium chloride solution into the mixed solution, finally, regulating the pH value of citric acid of the anti-felting finishing agent to 3.5 by using polybasic acid, and fully stirring for reaction;
s2: and adding glycerol into the anti-felting finishing agent, padding and finishing the wool fabric by using the anti-felting finishing agent, pre-drying, and then baking to obtain the anti-felted wool fabric.
The pH value of the anti-felting finishing agent is 3.5; the anti-felting finishing agent comprises, by weight, 15 parts of aqueous polyurethane emulsion, 0.5 part of sodium alginate, 5 parts of polyurethane cross-linking agent and 80 parts of water, wherein the solid content of the aqueous polyurethane emulsion is 40%; the molar ratio of the calcium chloride to sodium ions in the sodium alginate is 1.1:1, a step of; padding finishing bath ratio is 1:25, padding is carried out twice, padding residual rate is 80%, pre-baking temperature is 95-100 ℃, baking temperature is 135-140 ℃, and baking time is 90s.
Example 2
Example 2 is based on example 1, except that the anti-felting finish has a pH of 5 and the pH adjustor is succinic acid.
Example 3
Example 3 is based on example 1, except that the composition of the anti-felting finishing agent is 25 parts by weight of aqueous polyurethane emulsion, 4 parts by weight of sodium alginate, 1.5 parts by weight of polyurethane crosslinking agent pentanediol and 80 parts by weight of water, and the solid content of the aqueous polyurethane emulsion is 40%;
example 4
Example 4 is based on example 1, with the difference that the molar ratio of calcium chloride to sodium ions in sodium alginate is 1.3:1, a step of;
example 5

Comparative example 1
Comparative example 1 is based on example 1, except that the anti-felting finish comprises only end-capping polyurethane finish, the content of polyurethane finish in the anti-felting finish being the same as in example 1.
Comparative example 2 is an unfinished wool fabric.
Felting rate: wool fabric was washed 3 times according to the washing standard of the international wool office TM31 wool textile product, area shrinkage (%) = (area before washing-area after washing)/area before washing 100%.
Weight gain rate: the wool fabric before and after treatment was weighed, and the wool fabric weight gain rate = (weight after wool fabric finish-weight before wool fabric finish)/weight before wool fabric finish was 100%.
According to ZBW04003-1987, "method for testing fabric stiffness by inclined cantilever method", the slide-out length of a sample on an inclined surface bench, which means that the sample is extended from the platform portion and sags due to bending by the dead weight, is measured as follows:
1. the felting rates of examples 1-5 and comparative examples 1-2 were respectively: 4.38%, 4.17%, 3.85%, 3.97%, 4.42%, 9.75%, 19.73%;
