Embodiment 1

[0031] (1) After the cotton fabric is singed-desizing-dyed (or printed), the cotton fabric is grafted with a mixture of acrylamide and methacrylamide. The specific grafting process is: acrylamide and methacrylamide The mass ratio is 2:3, acrylamide and methacrylamide 10g / L, citric acid 5g / L, alkyl glycoside APG10 dosage 1g / L, ammonium persulfate, 0.8g / L, and the balance is deionized water. The bath ratio is 1:20, and the temperature is raised to 70°C at a rate of 1°C / min for 70 minutes. After the grafting reaction is completed, use 1g / L Pingping to add O, the bath ratio is 1:20, and wash with water at 85°C for 10min. Then wash with cold water for 10 minutes.

[0032] (2) Fabric padding water-based polyurethane finishing liquid in step (1), the formula of finishing liquid is: water-based polycarbonate class aliphatic polyurethane RU-13-442 (the product trade name of Stahl company) consumption 100g / L, Bayhydur The dosage of XP 2655 is 4% of that of RU-13-442, the dosage of car...

Embodiment 2

[0035] (1) After the cotton fabric is singed-desizing-dyed (or printed), the cotton fabric is grafted with a mixture of acrylamide and methacrylamide. The specific grafting process is: acrylamide and methacrylamide The mass ratio of acrylamide and methacrylamide is 3:2, 25g / L of acrylamide and methacrylamide, 3g / L of citric acid, 1g / L of alkyl glycoside APG10, 1.25g / L of ammonium persulfate, and the balance is deionized water. The bath ratio is 1:20, and the temperature is raised to 75°C at a rate of 1°C / min for 50 minutes. After the grafting reaction is completed, use 0.5g / L Pingping to add O, the bath ratio is 1:20, and wash with water at 80°C for 10-15min. Then wash with cold water for 15 minutes.

[0036] (2) fabric padding water-based polyurethane finishing liquid in step (1), the formula of finishing liquid is: water-based polycarbonate class aliphatic polyurethane RU-13-442 (the product trade name of Stahl company) consumption 80g / L, Bayhydur The dosage of XP 2655 is ...

Abstract

The invention discloses a processing method of formaldehyde-free cotton fabric with durable gloss. The processing method comprises the following steps of (1) singeing, desizing and dyeing (or printing) cotton grey cloth, grafting the cotton fabric with a mixed solution of acrylamide and methacrylamide, and washing with water after the grafting reaction is completed; padding the fabric in a waterborne polyurethane finishing liquid, and drying after padding the fabric in the finishing liquid; and calendering the fabric through an oil surface calendering machine, and calendering through a mirrorsurface calendering machine to obtain the cotton fabric with durable gloss. The fabric obtained through the method is free of formaldehyde and has good durable gloss. The process is convenient to operate and high in feasibility, and used raw materials are simple and easy to obtain. An assistant adopted by the invention has no formaldehyde or potential formaldehyde release problem in the whole process, and is simple in process flow and easy for industrial implementation.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a formaldehyde-free cotton fabric processing method with durable luster. Background technique [0002] After cotton fabric is calendered, the color of the fabric is more colorful and gorgeous, the pattern is pleasing to the eye, and it presents a soft luster. It is a fashionable fabric that is very popular in the market. In the early calendering, starch or polyvinyl alcohol was used as the calendering resin. By adjusting the amount of additives, calendering temperature, cloth humidity and other process factors, the calendered fabric showed a bright effect, but the luster of the fabric finished with this technology was poor in washing resistance. , the luster basically disappears after washing, so the early calendering fabrics are mainly used in interior decoration and other fields. Later, with the development of anti-shrinkage and anti-wrinkle finishing technology, resins or mo...
