The Principle Of Dyeing Of Blend Cationic Dyes Is Detailed

Aromatic sulfonamide is a series of aromatic polyamide fiber, known as the polyphenylene sulfone terephthalamide fiber, China has this aspect of independent intellectual property rights. Fang sulfone is a heat, high strength, high chemical stability, radiation resistance Blend Cationic Dyes

Electrical insulation and other properties of the fiber, its molecular structure is structured, with a high degree of crystallinity and degree of orientation, based on its high performance and excellent processing performance, the product is mainly used for special uniforms, fire clothes and other protective products, high temperature filtration Materials and electrical paper and other aspects.Blend Cationic Dyes

Aromatic sulfonamide is a series of aromatic polyamide fiber, known as the polyphenylene sulfone terephthalamide fiber, China has this aspect of independent intellectual property rights. Fang sulfone is a heat, high strength, high chemical stability, radiation resistance , Electrical insulation and other properties of the fiber, its molecular structure is structured, with a high degree of crystallinity and degree of orientation. Based on its high performance and excellent processing performance, the products are mainly used for special military uniforms, fire clothes and other protective products, high temperature filter materials and electrical paper, etc., Fang sulfone due to its degree of crystallinity and degree of orientation, Of the strong interaction, dyeing more difficult, the use of disperse dyes high temperature and high pressure dyeing, dyeing color is bleak and the dyeing rate is not high. The cationic dye carrier dyeing method was used to screen the non - toxic and tasteless environmental carrier, and the process optimization experiment was carried out.Blend Cationic Dyes The principle of carrier dyeing is to use the same organic material as the fiber structure to make it into the fiber interior, swelling the fiber, reduce the fabric structure of the tightness, so that the dye spread and dyeing.High temperature and high pressure is to accelerate the movement of dye molecules, The ideal carrier should be non-toxic, odorless, environmentally friendly, promote the effect of good, do not reduce the affinity of the dye, does not affect the color and fastness, easy to wash away, low cost of the material As can be seen from Table 1, the use of three kinds of carrier dyeing Blend Cationic Dyes
