The emergence of disperse dye -alkaline dyeing:When decentralized dye dyeing conventional polyester, the general dyeing bath is generally controlled (pH value is 5-6). Due to dyeing under acidic conditions, most of the scattered dye color light is the purest and high -dye rate. However, polyester si Read More

Cold -rolled pile staining, usually ethylene dyes. This is because the active base of the ethylene -type active dye is commonly used, which is very sensitive to alkali. In an alkaline bath, the reaction can be quickly disappeared, and the ethylene radon (-so2ch = CH2) with strong chemical activity c Read More

HardnessIt is generally believed that the hardness below 50 ppm has no impact, and 20ppm is already a good water.The water quality of the tube yarn is not the same, but the copper and iron ion content in the water should be paid attention.Usually active dyeing is better below 50ppm. The key is the m Read More
