The basic technological process of garment production includes eight processes: incoming inspection, discharging, cutting, sewing, buckle, ironing, garment inspection, packaging and warehousing.
Inspection and testing of materials: including color difference inspection, dimensional deviation inspection and defect inspection. After the cloth enters the factory, count the quantity and check the appearance and internal quality. Only those that meet the production requirements can be put into use. Controlling fabric quality is an important part of controlling finished product quality. Through the inspection and judgment of incoming fabrics, the genuine rate of clothing can be effectively improved. Material inspection includes shrinkage of elastic band, adhesion fastness of adhesive lining, smoothness of zipper and so on. Materials that do not meet the requirements will not be put into production.
Next is technical preparation: technical preparation is an important means to ensure the smooth progress of mass production and the final product meets customer requirements. Before mass production, technicians should first make technical preparations before production. Technical preparation includes three contents: the formulation of process list, the production of models and sample clothes. Craft sheet is a guiding document in garment processing, which puts forward detailed requirements for garment specifications, sewing, ironing and packaging. The details of garment accessories and stitch density are also expounded. Every process in garment processing should be carried out in strict accordance with the requirements of the process sheet. Sample production requires accurate size and complete specifications. The contour lines of related parts are matched accurately. The model should indicate the clothing model, location, specifications and quality requirements, and affix the composite seal of the model at the relevant splicing place. After making the process sheet and sample clothes, small batches of sample clothes can be produced, and the nonconformities can be corrected in time according to the requirements of customers and processes, so as to overcome technical difficulties and make the large-scale assembly line run smoothly. After the sample clothes are confirmed and signed by customers, it becomes one of the important inspection basis.
Layout: First, pre-shrink the layout of 1: 10, and draw the layout according to the sample drawing. "Integrity, rationality and economy" is the basic principle of layout.
Cutting: Each auxiliary material and cutting is called bed or knife. Cutting machine can improve production efficiency, save raw materials relatively, and ensure quality better than manual cutting. Generally, the fewer cutting layers, the higher the cost.
Sewing: Sewing marks and patterns are the basic elements of sewing. Clothing sewing can be divided into machine sewing and manual sewing according to style and craft style. In the process of sewing, assembly line operation is carried out. There is a flow chart when sewing.
