What are the dyeing processes used in denim fabrics?
According to different dyes, it is mainly divided into indigo dye dyeing, sulfur dye dyeing and reactive dye dyeing.
Indigo dye dyeing: The most traditional denim fabric is blue. The original classic blue was dyed with indigo dye, which is divided into natural indigo dye and synthetic indigo. dye. Natural indigo dye is extracted from indigo grass and other plants. It is a dye with a history of more than 3,000 years. There are also denim fabrics dyed with natural indigo dye, but synthetic indigo dye fabrics are more popular.
Natural indigo dyes generally produce lighter blue colors, while synthetic indigo dyes can produce darker colors. In addition to common indigo dyes, they can also Super indigo dyeing or extra deep indigo dyeing is achieved by increasing the amount of indigo dye used during dyeing.
Indigo dyed traditional denim fabrics, after stone grinding or rinsing, the surface of the fabric will appear white and clear, with a unique style; however, natural indigo resources are limited, the yield is low, and it is not suitable for large-scale production Dyeing, while synthetic indigo causes serious environmental pollution.
Sulfur dye dyeing: This is the most commonly used dyeing method for denim fabrics. It can be dyed with sulfur dyes alone, such as sulfur black dyeing of black denim fabrics; it can also be over-dyed with indigo dyes. , that is, the traditional indigo denim fabric is dyed again, such as indigo over-dyed with sulfur black, indigo over-dyed with sulfur grass green; it can also be over-dyed with different sulfur dyes, such as sulfur black over-dyed with sulfur blue, etc.

Why are denim fabrics soft and hard?
First of all, different weaving methods make the softness of the fabric different, and knitted denim fabrics are obviously softer; secondly, the way the fabric is washed determines its softness, such as enzyme washing The softness effect can be achieved. In addition, whether softener is added during washing and the amount of softener used will also lead to completely different softness; special processing techniques can also improve softness, such as flocking finishing and mercerizing treatment to a certain extent. Improves softness. In addition, the weight of the fabric also has an impact. Generally, thick fabrics will be less soft than light and thin fabrics.
Why do some denim fabrics appear old, horizontally grained, or sanded?
The most unique style of denim fabrics is the clear texture. This is because traditional denim fabrics only have warp dyeing, and the weft yarns maintain their original color, so that one side has color and the other side retains its original color. The yarn-dyed weaving method gives denim fabrics its own typical style. However, the decisive factor in the final style of denim fabrics is the washing method-
Ordinary washing: washing with clean water and softener to make the fabric softer, more comfortable, and visually more natural and more Clean, the color is slightly lighter than the original fabric after washing, and the feel is slightly softer.

Enzyme washing: Enzyme is a type of cellulase that can degrade fibers, allowing the cloth surface to fade and remove hair more gently, producing a “peach skin” effect. , and get long-lasting softness. It can also be used together with stone washing, which is called enzyme stone washing.
Sand washing: Add sand washing powder, bulking agent and other additives during washing to make the clothes have a certain fading effect and a sense of staleness after washing. If it is equipped with stone grinding, a layer of softness will be produced on the surface of the cloth after washing. Frost-white fluff and some softeners can make the fabric soft and soft after washing, thus improving the comfort of wearing.
Chemical washing: The purpose of fading is achieved by using strong alkali additives. After washing, the clothes will have a more obvious stale feeling. Adding softener will make the clothes soft and plump. Effect.
