How to dye nylon 6 fabrics with acidic dyesIn 1935, Dr. Carothers, American scientists and his team developed polyamide, commonly known as "nylon". Nylon has multiple varieties. At present, the most widely used polyamide is nylon 6,6 and nylon 6. Read More

On the surface, the flashing phenomenon is that the dyed color hue of cotton fiber and nylon fiber is inconsistent, that is, the hue is uneven. The root cause is that some dyed cotton dyes compete with nylon fiber. In actual production, the dyeing of primary colors and secondary colors can mak Read More

If it is a re-ordered color that is frequently produced, the pre-treatment process must be stable and consistent to ensure that the semi-finished products produced each time have the same gross effect, whiteness, and pH value. And each time before dyeing, the laboratory needs to make a sample, and t Read More

Los colorantes ácidos se refieren al grupo ácido en las moléculas de colorante, también conocido como colorante de anión, que se pueden combinar con grupos amino en moléculas de fibra de proteínas. Read More

Acid dyes refer to the acid group in the dye molecules, also known as anion dye, which can be combined with amino groups in protein fiber molecules. Read More

Scouring pleats are mostly found in high-count and high-density polyester-cotton fabrics and pure cotton thin fabrics. Due to the high hardness of water during production, scale is easy to form during steaming and washing and is easy to adhere to the cloth guide roller. Long-term production will for Read More

Color pulling, also known as color stripping, generally uses chemical reactions to destroy the combination of dyes on fibers and fibers, destroy the structure of dyes on fibers, and make dyes peel off fibers and cannot develop color. There are two main types of commonly used color removal agents: re Read More

As a kind of spandex elastic fiber, a polymeal polymethyl ester composed of a flexible chain segment and a rigid chain segment. It was successfully studied by Bayer in Germany in 1937. In 1959, it was produced by DuPont. Because it has many advantages and good quality, it is recognized by the peers, Read More

1. Unqualified color plasticityThe color fastness includes sun exposure, soap washing fastness, sweat staining fastness, friction fastness, sublimation fastness, ironing fastness, etc. These fastness is The dyeing process and external conditions are closely related. Therefore, whether the color fast Read More

1. Descripción general de los tintes ácidos Los colorantes ácidos se refieren al grupo de ácido en las moléculas de colorante, también conocido como colorante de anión, que se puede combinar con grupos amino en moléculas de fibra de proteínas con enlaces iónicos y aplicables bajo ácidos ácidos.

1. Overview of acid dyes Acid dyes refer to the acid group in the dye molecules, also known as anion dye, which can be combined with amino groups in protein fiber molecules with ion bonds and applicable under acidic, weak acids or neutral conditions. Read More

Many people always confuse dyeing and printing, but in fact there are obvious differences between the two. Next, let me give you a popular science about the difference between dyeing and printing. 1. The difference between dyeing and printing has the following eight points:1. Printing is better at c Read More
