Technical Field
The invention relates to a method for crease-resistant finishing of cotton fabrics, belonging to the technical field of dyeing and finishing.
Background
The pure cotton fabric has the advantages of comfort in wearing, air permeability, moisture absorption, soft hand feeling and the like, but the cotton fabric has the defects of poor elasticity, easy deformation, easy wrinkling, need of ironing after washing and the like in the using process, so that the cotton fabric cannot keep a smooth appearance after washing and in the using process. Therefore, in order to improve the appearance of cotton fabric in the wearing process, maintain the stability of the shape of the cotton fabric and improve the wearability of the cotton fabric, crease-resistant finishing of pure cotton garment materials is necessary.
At present, the anti-wrinkle finishing agent commonly used in the anti-wrinkle finishing is mainly urea-formaldehyde derivative resin finishing agent, namely, the structure of the anti-wrinkle finishing agent contains an N-hydroxymethyl derivative structure, such as 2D or modified 2D resin. The fabrics finished by the resin finishing agent have the problem of releasing formaldehyde. There is therefore a need for safer formaldehyde-free crease-resistant finishes.
The formaldehyde-free crease-resistant finishing agent comprises natural high molecular compounds such as glyoxal-amide compounds, reactive organosilicon compounds, water-based thermal reactive polyurethane, chitosan and polycarboxylic acid compounds, wherein the cotton fabrics finished by the formaldehyde-free finishing agent such as glyoxal-amide compounds have the defects of yellowing, serious strength loss or poor finishing effect, and the polycarboxylic acid compounds are considered to be most likely to replace N-hydroxymethyl finishing agents by comprehensively considering the factors in various aspects such as crease resistance, strength retention rate, environmental protection, cost, color change and the like of the finished fabrics. At present, the polycarboxylic acid compounds used for crease-resistant finishing are 1,2,3, 4-butanetetracarboxylic acid, citric acid, maleic acid, itaconic acid, polymaleic acid and the like, wherein the 1,2,3, 4-butanetetracarboxylic acid and citric acid have the most application development prospect, but the 1,2,3, 4-butanetetracarboxylic acid is higher in cost and is not suitable for large-scale application, and the fabrics treated by the citric acid are easy to yellow. Malic acid is used as a polycarboxylic acid, has the effects of resisting wrinkles, preventing yellowing, releasing no formaldehyde, and having low price but large strength loss, and seriously influences the wearability of the fabric.

step two: oven drying, baking, soaping, and oven drying.
In the first step, the concentration of malic acid is 2.0-10.0 wt%, the concentration of sodium hypophosphite is 2.0-10.0 wt%, the concentration of triethanolamine stearate quaternary ammonium salt softener is 0.2 wt%, the concentration of penetrating agent JFC is 0.08 wt%, and the balance is water.
