After dyeing, the shoelace show different colors. Are all the shoelace dyed in one way? In fact, there are many dyes, and different dyes are suitable for different materials of shoelace. Common dyes include acid dyes, alkaline dyes, direct dyes, disperse dyes, reactive dyes, vat dyes and so on. Different dyes are suitable for different fiber dyeing. Let's look at the specific analysis below.
Acidic dyes are generally suitable for protein fibers, nylon fibers, silk and so on. Their main characteristics are bright color, but they are not resistant to washing and dry cleaning. They are widely used at present.
Basic dyes are mainly suitable for acrylic, polyester, nylon, fibers and protein fibers. Their main characteristics are bright colour, especially for man-made fibers. However, they are not washable and light-resistant for natural cellulose and protein fabrics.
Direct dyes are more suitable for cellulose fabrics with poor wash fastness and different light resistance, but the wash color of modified direct dyes will be improved very well.
Disperse dyes are more suitable for viscose, acrylic, nylon, polyester and so on, with different washing fastness, better polyester and worse viscose. Azo fuels are suitable for cellulose fabrics, and more suitable for brilliant color.
Reactive dyes are mostly used in cellulose fabrics with bright colour, light resistance, good washing and friction resistance. Sulfur dyes are suitable for cellulose fabrics with dark colour, mainly Tibetan blue, black and brown, excellent light and water resistance, poor chlorine bleaching resistance, and long-term storage of fabrics will destroy the fibers.
The vat dyes are suitable for cellulose fabrics. They are light-resistant, washable, chlorine-resistant and other oxidative bleaching.
Above is the introduction about different dyes for different materials of shoelace. I hope it can help you.
