Problems solved by technology

[0002] N-methylol amide resins are still the most widely used non-iron finishing agents for natural fiber fabrics, and the most representative one is 2D resins, but they have the disadvantages of releasing formaldehyde, reducing the strength of finished fabrics, and poor hand feeling.
In order to meet the requirements of environmental protection, an ultra-low formaldehyde non-ironing finishing agent was developed, which improved the safety to a certain extent, but the fabric hand feeling and strength were not improved, nor did it fundamentally solve the problem of formaldehyde release
In recent years, formaldehyde-free non-iron finishing agents have been developed at home and abroad, but there are few industrial applications, the finishing process is complicated, and there are disadvantages such as high price and non-ironing effect is not as good as 2D resin.
Silk fabrics are prone to yellowing when baked at high temperature. The non-ironing finishing process of silk fabrics is different from that of cotton and linen. The baking temperature should not be too high, so many non-ironing finishing agents that require high-temperature crosslinking cannot be used.

Abstract

The invention discloses a formaldehyde-free, non-ironing and anti-wrinkling silk fabric finishing technology. The formaldehyde-free, non-ironing and anti-wrinkling silk fabric finishing technology comprises the following steps: pre-shrinking silk fabric, then uniformly introducing polyurethane-organosilicone non-ironing and anti-wrinkling finishing liquid into the silk fabric by a padding process,removing moisture by a drying process, and performing a high-temperature baking process on the dried silk fabric to obtain formaldehyde-free, non-ironing and anti-wrinkling silk fabric. By the formaldehyde-free, non-ironing and anti-wrinkling silk fabric finishing technology, non-ironing finishing of the silk fabric is achieved, the silk fabric can be endowed with good resilience, washability andfull handfeeling; meanwhile, the polyurethane-organosilicone non-ironing and anti-wrinkling finishing liquid does not contain formaldehyde, so that the safety of the finished silk fabric is ensured from the source.
