The complete production process of socks
The complete production process of socks
Socks are an indispensable clothing accessory in daily life. They not only provide warmth and comfort, but also serve as decoration. So, how does a pair of socks go from raw materials to finished products? This article will introduce the complete production process of socks in detail.
1. Design and proofing
Design: The production of socks begins at the design stage. Designers will design the style, pattern and Color Of Socks according to market demand, fashion trends and target customer groups.
Proofing: After the design is completed, samples need to be made to test the actual effect of the design. During the proofing process, the samples will be adjusted many times until the final confirmation.
2. Raw material preparation
Yarn selection: Select suitable yarns according to design requirements, such as cotton, polyester, nylon, wool, etc., or their blended materials.
Yarn dyeing: Dye the yarn into the required color. The dyeing process needs to control the temperature, time and dye dosage to ensure the uniformity and fastness of the color.
3. Weaving
Weaving socks: The dyed yarn is woven through the sock machine. The sock machine weaves the yarn into the shape of socks according to the pre-set program. This step is a highly automated link.
Sewing: After weaving, the various parts of the socks need to be sewn together, such as the toe, heel and mouth.
4. Finishing
Shaping: The socks are shaped to maintain the stability of their shape and size.
Toe stitching: The toe and heel parts of the socks are sewn together to make them more secure.
Trimming: Remove excess thread and fluff on the socks to ensure the surface of the socks is flat.
5. Dyeing and printing
Dyeing: For undyed white socks, dyeing can be performed after weaving.

High selectivity and few side reactions: Bioenzyme technology has the characteristics of high selectivity and few side reactions, and has strong catalytic activity and catalytic efficiency. It can greatly improve the rate and yield of chemical reactions and reduce the reaction Temperature and energy consumption
Environmental protection: Bioenzyme catalytic sewage treatment technology is a green and environmentally friendly emerging technology that does not harm the environment. Therefore, it can economically complete the same work without harming the environment
Promote resource recycling: Bioenzyme technology can convert organic matter into small molecules that are easy to use, realize resource reuse, and reduce environmental pollution
Improve environmental self-purification ability: Environmental biotechnology can be used to treat environmental media that are difficult to treat by other methods, that is, bioremediation technology can be used to purify the environment, so that polluted valuable resources such as water resources and soil can be reused, and the self-purification ability of the environment can be further enhanced
In summary, bioenzyme technology has many benefits in the field of environmental protection. It can not only improve treatment efficiency and reduce waste emissions, but also protect the environment and promote resource recycling. It is an efficient and environmentally friendly green technology.)
8. Environmentally friendly auxiliaries
Green printing and dyeing auxiliaries: use environmentally friendly auxiliaries with excellent performance, low toxicity and good biodegradability to reduce the impact on the environment
(There are many types of green dyeing and printing auxiliaries, which have significant advantages in environmental protection and sustainable development. The following are some of the main types of green dyeing and printing auxiliaries:
Formaldehyde-free dye fixative: This type of dye fixative does not contain formaldehyde and is safer for the environment and human body. They achieve the fixation of fabric dyes through functional groups or ion pairs, such as polyamine fixing agents and cationic fixing agents
