Problems solved by technology

Unfortunately, however, urea-based reagents have significant drawbacks
For example, DMDHEU, one of the preferred commercial permanent press agents in the market, provides excellent permanent press properties, but DMDHEU itself causes considerable Loss of fabric strength, as well as color enhancement and rough hand
Furthermore, its by-product formaldehyde is environmentally unacceptable as it is a toxic substance
[0008] Other chemistries for crosslinking cellulose have been investigated, including vinyl sulfones, triazines, epichlorohydrin, and polycarboxylates, however, these have not been commercialized so far
These technologies have encountered different technical problems and exhibited substandard performance

Embodiment 1

[0055] emulsion polymerization

[0056] Polymerization is accomplished in an aqueous medium. In a typical implementation, at N 2 6 ml of deionized water, 0.02 g of SDS and 0.01 mol of monomer 1 were stirred under atmosphere for 30 min. After further stirring for 5 minutes at 60 °C, the initiator (0.0001 mol Na 2 S 2 o 8 ). in N 2 Polymerization was carried out at 60°C for 24 hours under air.

Embodiment 2

[0058] emulsion polymerization

[0059] except in N 2 0.01 mol of monomer 2 was stirred under gas for 30 minutes and the process of Example 1 was repeated. Add the initiator (0.003mol Na 2 S 2 o 8 ). in N 2 Polymerization was carried out at 90°C for 24 hours under air.

Embodiment 3

[0061] emulsion polymerization

[0062] except in N 2 0.01 mol of monomer 4 was stirred under gas for 30 minutes and the process of Example 1 was repeated. Add the initiator (0.004mol Na 2 S 2 o 8 ). in N 2 Polymerization was carried out at 80°C for 24 hours under air.

Abstract

The present invention relates to a method capable of utilizing poly (carboxylic acid) nano particles to implement anti-crease treatment of cotton fabric. Said invention designs and synthesizes polycarboxylic acid, and provides its property for raising crease resistance of cellulose fabrics. Said invention utilizes the emulsification and polymerization of vinyl monomer to prepare the described nano particles. Said nano particles can be used for raising durable press property of cotton fabrics.

Description

technical field [0001] The present invention relates to emulsions and methods for treating cotton fabrics, especially emulsions containing poly(carboxylic acid) nanoparticles, and methods for anti-wrinkle treatment of cotton fabrics using said emulsions. Background of the invention [0002] Most clothing in the world market is made from cellulose fibers, such as cotton. A disadvantage of conventional cellulosic fibers is that when exposed to an aqueous medium (eg, conventional washing), the fiber size changes, causing shrinkage and wrinkling of the garment. As a result, this requires the consumer to iron or dry clean the garments in order to maintain and / or restore optimum garment appearance, which is laborious and / or expensive. The major current commercial requirements for "high performance" cellulosic fabrics are minimal garment maintenance (eg, ironing and dry cleaning) and extended utility life. Textile manufacturers, including our company, have responded to this deman...
