Problems solved by technology

Although this method has played a positive role in promoting the formaldehyde-free durable press finishing of fabrics, the non-ironing effect and fastness of the finished fabrics are still not ideal. Generally, the initial DP level does not exceed level 4, and the DP level after five washings is still not satisfactory. The grade is 3~3.2, and the fabric strength retention rate is about 50~60%.

Embodiment 1

[0021] Add 81.2 grams of maleic acid, 80.0 grams of acrylic acid, 40.0 grams of ethyl acrylate and 300 grams of deionized water into a 1-liter four-necked bottle, and stir to mix evenly. Use a constant temperature water bath to control the temperature of the material at about 70° C., protect it with nitrogen gas, and slowly add 30 g of a 30% mass concentration of ammonium persulfate aqueous solution dropwise under stirring. After the initiator is added dropwise within 1.5h, continue stirring at constant temperature for 0.5h to end the reaction and obtain a light yellow translucent solution. Add 10.1 grams of ethanolamine and 2.0 grams of sodium citrate, and add an appropriate amount of deionized water to adjust the mass concentration of the system. to 30%.

Embodiment 2

[0023] Add 60.6 grams of maleic acid, 52.3 grams of itaconic acid, 42.5 grams of ethyl methacrylate and 300 grams of deionized water into a 1-liter four-necked bottle, and stir to mix evenly. Use a constant temperature water bath to control the temperature of the material at about 75° C., protect it with nitrogen, and slowly add 35 g of a 30% mass concentration of ammonium persulfate aqueous solution dropwise under stirring. After the initiator is added dropwise within 2 hours, continue stirring at constant temperature for 1 hour to end the reaction and obtain a light yellow translucent solution. Add 9.0 grams of diethanolamine and 2.3 grams of disodium citrate, and add an appropriate amount of deionized water to adjust the mass concentration of the system. to 30%.

Embodiment 3

[0025] Add 46.4 grams of maleic acid, 104.4 grams of itaconic acid, 7.2 grams of acrylic acid, 25.6 grams of butyl acrylate and 350 grams of deionized water into a 1-liter four-necked bottle, and stir and mix evenly. A constant temperature water bath is used to control the temperature of the material at about 80° C., and under nitrogen protection, 40 g of a 30% mass concentration AIBA aqueous solution is slowly added dropwise under stirring. After the initiator is added dropwise within 2.5 hours, continue to stir at a constant temperature for 0.5 hours to end the reaction and obtain a light yellow translucent solution. Add 11.4 grams of triethanolamine and 3.7 grams of trisodium citrate, and add an appropriate amount of deionized water to reduce the quality of the system. Adjust the concentration to 30%.

Abstract

The invention discloses a non-iron crease-resistant finishing agent of formaldehyde-free cellulose fabrics and a preparation method thereof, aiming at the problem that the prior non-iron crease-resistant finishing agent has high requirements for the raw materials used for synthesis or has no ideal non-iron effect and firmness on the fabrics. The non-iron crease-resistant finishing agent is composed of unsaturated acid monomer and acrylate that are polymerized in aqueous phase under the actions of initiator, regulator and catalyst, the regulator is convenient for performing penetration and esterification cross-link reaction, and has good cross-link effect, the catalyst has good catalyzing effect and complete reaction. The non-iron crease-resistant finishing agent has the advantages of outstanding non-ironing crease-resistance performance, less yellowing and higher strength reservation.

Description

technical field [0001] The invention relates to the field of high molecular polymers, in particular to a formaldehyde-free cellulose and a wrinkle-free finishing agent for fabrics thereof and a preparation method thereof. Background technique [0002] In recent years, with the strengthening of people's awareness of environmental protection, formaldehyde-free non-ironing finishing agents have become an important research topic in the field of non-ironing finishing agents. At present, polycarboxylic acid is the formaldehyde-free finishing agent that has the most potential to replace N-methylol amide compounds, and wherein, butane tetracarboxylic acid (BTCA) has the best finishing effect, but due to its high price (approx. 10 times that of 2D resin), which hinders its industrialized large-scale production; citric acid (CA) is cheap, safe and non-toxic, but the finishing effect is not as good as BTCA, and there are problems such as yellowing and poor wash fastness, and it has no...
