The unique application of DMDEE bimorpholine diethyl ether in textile coatings: Enhanced softness and wear resistance

Introduction

In the modern textile industry, coated fabrics are highly favored for their versatility and high performance. Coated fabrics can not only provide waterproof, stain-proof, UV-proof properties, but also enhance the softness and wear resistance of textiles. Among these coating materials, DMDEE (bimorpholine diethyl ether) is a highly efficient catalyst and additive, and has gradually become an important component in the field of textile coatings. This article will explore the unique application of DMDEE in textile coatings in depth, analyze how it enhances the softness and wear resistance of textiles, and provide detailed product parameters and application examples.

1. Basic characteristics of DMDEE

2. Application of DMDEE in textile coatings

2.1 Enhance softness

The softness of textiles is one of the important considerations when consumers choose products. The application of DMDEE in textile coatings can significantly improve the softness of textiles, which are specifically reflected in the following aspects:

2.1.1 Improve coating elasticity

As a catalyst for polyurethane reaction, DMDEE can promote the formation and cross-linking of polyurethane molecular chains, thereby enhancing the elasticity of the coating. A well-elastic coating can better adapt to the deformation of textiles, making the fabric softer and more comfortable during wear.

2.1.2 Reduce coating hardness

The addition of DMDEE can adjust the hardness of the coating to make it softer. By adjusting the amount of DMDEE added, the hardness of the coating can be precisely controlled to meet the softness requirements of different textiles.

2.1.3 Improve coating adhesion

DMDEE can enhance adhesion between the coating and the textile substrate, making the coating more evenly distributed on the textile surface. This not only improves the softness of the coating, but also prevents peeling or cracking of the coating during use.

2.2 Enhanced wear resistance

Abrasion resistance is one of the important indicators to measure the service life of textiles. The application of DMDEE in textile coatings can significantly improve the wear resistance of textiles, which are specifically reflected in the following aspects:

2.2.1 Improve coating strength

DMDEE can promote cross-linking of polyurethane molecular chains and form a denser coating structure. This structure can effectively resist external friction and wear, thereby improving the wear resistance of textiles.

2.2.2 Enhance the toughness of the coating

The addition of DMDEE can improve the toughness of the coating, making it less likely to break or break when subjected to external forces. This toughness not only extends the service life of the textile, but also maintains the appearance of the textile.

2.2.3 Improve the fatigue resistance of the coating

DMDEE can enhance the fatigue resistance of the coating, so that it can maintain good performance after multiple frictions or stretches. This fatigue resistance is particularly important for frequently used textiles (such as sportswear, work clothes, etc.).
