The production process of fabric is a complex process, involving multiple links such as spinning, weaving and finishing. The following is the general production process and key processes of fabrics:
1. Spinning: Spinning is the process of converting fiber materials into yarn. First, the raw fibers are cleaned and separated to remove impurities and unwanted parts. The fiber material is then drawn into elongated yarns and subjected to processes such as twisting, twist adjustment, and spinning into threads. The key processes of spinning include carding, drafting, twist adjustment and spinning.
2. Weaving: Weaving is the process of interweaving yarns into fabric. In this process, warp yarns (longitudinal to the fabric) and weft yarns (long to the transverse direction of the fabric) are interlaced and accomplished by movements on a loom. The key processes of weaving include weft sizing, warp drawing, fabric equipment and weaving.
3. Finishing: Finishing is the treatment of fabrics to change their appearance, feel and performance. The main purpose is to make the fabric more comfortable, durable and functional. The key processes of post-finishing include dyeing, printing, finishing, smoothing and waterproofing. Among them, dyeing and printing are to color or print patterns on the fabric; finishing can improve the appearance and gloss of the fabric; smoothing is to remove wrinkles and make the fabric smooth; waterproofing can increase the waterproof performance of the fabric.
In the fabric production process, there are some other auxiliary processes, such as pre-shrinking, sanding, embroidery, coating, etc., to meet different requirements and Innovative design.
It should be noted that different types of fabrics may have different production processes. For example, cotton fabrics and polyester fabrics are made differently because they have different fiber properties and usage requirements.
The above is a brief introduction to the general production process and key techniques of fabrics. In actual production, each specific fabric variety has its own specific process requirements and processes. Quality must be strictly controlled in every link to ensure compliance with fabric requirements.
