7 ways to bleach towels

The finished towels on the market are white or colored, this is not the original color of the towels, need to be bleached. Towel just finished weaving off the machine is yellow, called rough, this is the original color of cotton yarn. There are several ways to bleach towels:



1, bleaching and dyeing: The White, add white, spiral white, reactive dyeing, Shilin Dyeing.
2, White: Towel directly boiled, boiled according to customer demand plus soft.
3, Add White: Towel direct boiling plus fluorescence, after according to customer demand plus soft.
4, SPIRAL WHITE: Towel first brush hair, brush hair after scouring and fluorescence, and then according to customer demand and soft.
5.Reactive dyeing: Reactive Dyes and fibers through the dye molecules contained in the reactive group of chemical reaction, so that the dye and fiber to form a macromolecule, and the fabric dyed. Reactive wet processing fastness, good levelness, but not resistant to chlorine. When washing this kind of fabric, part can not chlorine bleach, can oxygen bleach.



6.Vat Dyes (VAT dyes) are insoluble in water and can not be directly used in fabric dyeing. It is necessary to reduce the dyes to the sodium salt of cryptochromes under alkaline conditions with a reducing agent (insurance powder) , and then adsorb the dyes on the fibers Then, after oxidation by air or other oxidants, the leucophore reverts to an insoluble dye on the fiber. Due to the particularity of the dyeing process, the dyeing permeability of the Shilin is poor, and the phenomenon of color difference flower often occurs. Shilin color is light-resistant, washable and chlorine-resistant, but not resistant to rubbing and poor fastness to 7.rubbing.Softness: After washing, the fabric loses its previous softness and becomes stiff. The addition of the softener makes the Surfactant adsorb on the surface of the fiber, prevents the deposition of metal salts, and because the softener reduces the friction between the fibers and increases the wettability, it makes the fabric loose, soft, feel good and wrinkle resistant after washing And has antistatic properties. Softener has lipophilicity, hydrophilicity. The use of softener according to the needs of customers.



So much for the bleaching and softening of towels. Do you think it will help you
