How can I maintain the color fastness of hydrophilic nonwovens?

  • Release on:2019-09-02
With the widespread use of hydrophilic nonwovens(Hydrophilic Non Woven Fabric Wholesale) in many industries, people are increasingly demanding its color,which makes it a process of coloring in production, how to maintain itsprinting color Degree?

1. For dyes with hydrophilicity, use dyeswith good oxidation resistance; for protein fibers, dyes with good resistanceto reduction or weak oxidizing additives should be used; other fibers should bedyed according to the influence of fading.

2. The dye should be selected according tothe color depth. The darker the color, the better the light fastness to light.Color matching should be selected for dyes with good light stability and compatibility.

3. In order to enhance the photo oxidative stability of the azo group in the molecular structure of the hydrophilic non-woven(Soft Nonwovens Manufacturer) dye, in the process of dye synthesis, some strong electron-with drawing groups are usually introduced in the or tho position of the azo group, thereby reducing the azo-based gas. The electron cloud density of anatom.

For hydrophilic nonwoven fabrics(Hydrophilic Nonwovens Factory) tomaintain good printing fastness, it is important to strictly control the choice of dyes, and at the same time master the dyeing process and process requirements, so that the color can be firm and does not fade.
