Human beings were born just like animals, they can only rely on hair to cover the body to keep warm. Later, with the development of wisdom, humans began to peel off the fur from hunting animals and wrap them as the earliest clothes. Later, ancient humans began to make simple clothes from various materials such as hemp fibers and grasses that they could find around them. This was probably the earliest weaving. The ruins of the cave people’s residence were discovered in Longgu Mountain, Zhoukoudian, Fangshan County, Beijing. In the cave where they lived and lived, a bone needle and some perforated stone beads were found, 18,000 years ago. This discovery shows that as far back as the Neolithic Age, our ancestors created sewing tools to sew animal skin clothes. This was the earliest clothing fabric.
Dyeing is a process of transferring colorants to fibers, yarns, fabrics and finished garments. Colorants include liquid dyes or fine powdered pigments.
Before the mid-19th century, the main sources of color dyes and pigments were animals, plants and minerals; the main sources of dyes in plants were jam, rhizomes, bark and leaves. These natural dyes are almost no longer processed during use (even if necessary, they are processed in small amounts). The earliest synthetic dye was called Mauvine or Aniline purple, which was accidentally discovered in a failed drug experiment in 1865.
The industrial revolution was a catalyst for the large-scale development of the fabric industry, and it led to the development of synthetic dyes. The result is more colors and stronger color fastness. In addition, the color of textile fabric manufacturers has become more stable under the condition of continuous wearing and washing. Nowadays, different fabric properties and different types of dyes used in different fabric production stages are different.
Dyeing is divided into: yarn dyeing, fabric dyeing, garment dyeing, and anti-dyeing dyeing.
