Plant-dyed textile production
Manual production
The ancient method of plant dyeing is hand-dyed by hand, and the plant dyeing techniques that have been handed down to us now are also hand-dyed, such as stranded valerian (tie-dye), wax valerian (batik), and pinch valerian. Most of the ancient plant dyeing directly dyed the fabric. Advantages of hand-dyeing: 1 Less quantity required. 2 Can dye fabric directly, fast cycle. 3 Each finished product is unique. Disadvantages: 1 Cannot be mass produced. 2 Cannot be repeated. 3 Unstable fastness.
Mechanized production
In addition to the inherited ancient method of handcrafted vegetable dyeing, it is now possible to dye loose fibers with natural dyes [1], i.e., natural fibers such as cotton, hirsutum, and wool, with vegetable pigments.
The specific process of this method applied to the textile industry is: fiber plant dyeing - spinning - weaving - finished product. The advantages of this process are: 1. It can be produced according to different requirements, such as the choice of raw material fiber in the first step, the choice of yarn specifications in the second step, such as solid color or color spinning and yarn count, and the choice of fabric style in the third step, such as woven or knitted, etc. 2. Batch production, as well as repeat production. Disadvantages of this method: 1 Longer cycle time, 3-7 days for fiber plant dyeing, 15-20 days for spinning, and 7-10 days for finished fabrics. 2 Mechanized production needs to meet the production requirements of the equipment, i.e., it requires a starting order.
