Problems solved by technology

After the fabric is finished without ironing, the presence of chemical bonds between the fiber molecular chains increases its brittleness, which leads to a decrease in the overall strength.
[0007] (2) Non-ironing finishing is carried out under acidic conditions, which will degrade the fibers and reduce the strength of the fabric
[0009] (4) As the amount of finishing agent increases, there will be too much cross-linked resin on the fabric, which will affect the feel of the fabric

Abstract

This invention relates to the tidying solution for the spin industrial area, which is special about the cockle protection and permanent press tidying solution. The ingredient of pre liter solution is modified 2D resin 60-120g, DNUG resin 60-120g, dicyanogenamine 1-5g, catalyzer 5-50g, and the other is water. The modified 2D resin is the dihydroxymethyldihydroxyethyleneurea, the DNUG resin is the dimethylureaglyoxal. Adopting the above technical profile, it can completely resolve the content of residual formaldehyde is high after the process of permanent press, the textile strength is low, the anti abrading is low, and it is easy to break down. The textile after the processing by this invention has low residual formaldehyde, good anti crinkle, and the strength of the textile reduces and the anti abrading increases.

Description

technical field [0001] The invention relates to a finishing agent in the field of textile industry, in particular to an anti-wrinkle and non-ironing finishing agent. Background technique [0002] With the improvement of people's living standards, people's concept of clothing has changed greatly. The clothing requires not only natural appearance, comfortable and economical, but also easy cooking during consumption. Non-ironing finishing is to make pure cotton fabrics not only have the characteristics of natural fibers such as comfort, breathability, and soft hand feeling, but also have good non-ironing performance and dry and wet wrinkle resistance according to the needs of the current domestic and foreign markets. [0003] Non-ironing finishing of cotton fabrics is to improve the elasticity, wrinkle recovery angle and dimensional stability of cotton fabrics. Cotton fibers are divided into two parts, the crystalline region and the amorphous region. The amorphous part deter...
