2018-09-01 15:19 | writer: admin

The color fastness of flame retardant fabrics refers to the resistance of flame retardant fabrics to physical and chemical effects. The fastness rating is evaluated according to the color change of the sample and the stain of the undyed fabric. The color fastness test of flame retardant fabrics is a routine test item in the internal quality test of textiles, and the color fastness of flame retardant fabrics has become one of the important indexes to evaluate their quality.
1. Improvement of color fastness of flame retardant fabrics, such as dry and wet rubbing color fastness, acid and alkali perspiration color fastness, dry cleaning color fastness, soap/washing color fastness, water/water washing color fastness, light/sunlight fastness, salt/chlorine fastness, color fastness to sob, saliva color fastness, etc. Xinxiang Yulong Textile Co., Ltd. uses excellent additives to specialize in the treatment of flame retardant fabrics, so that the color fastness of flame retardant fabrics has been improved to the greatest extent. After treatment, the color fastness of flame retardant fabrics has reached at least three levels of testing standards.
2. Removal of banned dyes and additives in flame retardant fabrics, such as banned azo dye intermediates, heavy metals, formaldehyde, disperse sensitized dyes, carcinogenic dyes, APEO, etc. The unique finishing and dyeing process of Xinxiang Yulong Textile Co., Ltd. specializes in the treatment of flame retardant fabrics, so that the harmful substances exceeding the standard in the flame retardant fabrics can be removed to the greatest extent.
3. Improvement and improvement of physical properties of flame retardant fabrics. Physical properties of flame retardant fabrics refer to breaking strength, tensile strength, tear strength, tear strength, stiffness and softness, pilling and wear resistance, PH value, etc.
The flame retardant fabrics produced by Xinxiang Yulong Textile Co., Ltd. have the characteristics of strong hygroscopicity of cotton fiber. They are easy to dye and dry after washing. Flame retardant fabrics have good stability; its shrinkage rate is small, with the characteristics of tall and straight, not easy to wrinkle, easy to wash, fast drying, well received by customers.
