Complete collection of garment production process flow
(A) flour accessories into the factory inspection
After the fabric enters the factory, the quantity should be counted and the appearance and internal quality should be tested. Only when it meets the production requirements can it be put into use. Before mass production, technical preparations should be made, including the formulation of process list and sample clothes, and the sample clothes can not enter the next production process until they are confirmed by customers. Fabric is cut and sewn into semi-finished products. After some woven fabrics are made into semi-finished products, according to special technological requirements, post-finishing processing must be carried out, such as clothing washing, clothing sand washing, wrinkle effect treatment and so on. Finally, it is packaged and put into storage after passing the inspection.
(B) the purpose and requirements of fabric inspection
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.
Fabric inspection includes appearance quality and internal quality. Externally, we mainly investigate whether the fabric is damaged, dyed, weaving defects, color difference, etc. Sand washed fabrics should also pay attention to whether there are sand washing defects such as sand marks, dead pleats and splits. Defects that affect the appearance should be marked during inspection and avoided during cutting.
The inherent quality of fabric mainly includes shrinkage, color fastness and gram weight (mm, oz). When sampling, representative samples of different varieties and colors produced by different manufacturers should be cut for inspection to ensure the accuracy of the data.
At the same time, the auxiliary materials entering the factory should also be inspected, such as the shrinkage of elastic band, the adhesion fastness of adhesive lining and the smoothness of zipper. Accessories that fail to meet the requirements shall not be put into production.
(3) The main contents of technical preparation
Before mass production, technicians should first make technical preparations before mass production. Technical preparation includes three contents: the formulation of process list, the production of models and sample clothes. Technical preparation is an important means to ensure the smooth progress of mass production and the final product meets customer requirements.
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 shall indicate the number, position, specification, direction and quality requirements of the clothing model, and affix the composite seal of the model at the relevant splicing place.
After the formulation of the process sheet and sample clothes, small batches of sample clothes can be produced, and the discrepancies can be corrected in time according to the requirements of customers and processes, and technical research can be carried out to 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.
(4) Cutting process requirements
Before cutting, draw a typesetting diagram according to the template. "Integrity, rationality and economy" is the basic principle of layout. The main technological requirements in the cutting process are as follows: (1) Count the quantity when dragging materials, and pay attention to avoid defects. (2) Different batches of dyed or sand-washed fabrics should be cut in batches to prevent color difference on the same garment. For a fabric with color difference, color difference typesetting is needed. (3) Pay attention to the straightness of the silk grain of the fabric and whether the silk thread direction of the garment meets the technological requirements. Don't spread velvet fabrics (such as velvet, velvet, corduroy, etc.). ) backward, otherwise it will affect the color depth of the clothing. (4) For plaid fabrics, pay attention to the alignment and positioning of each layer of plaid when dragging materials to ensure the consistency and symmetry of plaid in clothing. (5) Cutting requires accurate cutting and straight and smooth lines. Paving type should not be too thick, and there should be no deviation between the upper and lower layers of cloth. (6) cut the edge according to the template alignment mark. (7) When using taper hole marking, care should be taken not to affect the appearance of clothing. After cutting, count the number, check the number of pieces, bundle them in piles according to the clothing specifications, and affix a ticket label, indicating the payment number, location and specifications.
(5) Sewing and sewing
Sewing and sewing are the central processes of garment processing, and garment sewing can be divided into machine sewing and manual sewing according to styles and technological styles. In the process of sewing, assembly line operation is carried out.
Adhesive lining is widely used in garment processing. Its function is to simplify the sewing process, make the clothing quality uniform, prevent deformation and wrinkling, and play a certain role in clothing modeling. Most of them are non-woven fabrics, woven fabrics and knitwear. The use of adhesive lining should be selected according to the fabric and parts of clothing, and the time, temperature and pressure of adhesion should be accurately grasped to achieve better results.
(6) keyhole nail buckle
Buttonholes and buttons on clothes are usually machined. According to its shape, buttonholes can be divided into flat buttonholes and eye buttonholes, commonly known as sleeping buttonholes and pigeon eyes.
Sleeping holes are widely used in thin clothing products such as shirts, skirts and trousers. Pigeon eye holes are mostly used for coats with thick fabrics such as tops and suits. Pay attention to the following points in keyhole: (1) Whether the buttonhole position is correct. (2) Whether the buttonhole size matches the button size and thickness. (3) Whether the buttonhole opening is cut. (4) For elastic (elastic) or thin fabrics, it is necessary to consider using keyhole holes to reinforce the inner layer. The sewing of buttons should correspond to the position of buttonholes, otherwise the clothes will be deformed and skewed because of inaccurate buttonholes. When buttoning, we should also pay attention to whether the number and strength of buttoning lines are enough to prevent the buttons from falling off, and whether the number of buttoning lines of thick fabric clothing is sufficient.
(7) ironing
Ironing people often use "three-point sewing and seven-point ironing" to emphasize that ironing is an important process in garment processing.
Avoid the following phenomena: (1) Too high ironing temperature and too long ironing time lead to aurora and scorching on the surface of clothes. (2) Leave tiny folds and wrinkles on the garment surface. (3) There are scalded parts.
(8) Clothing inspection
Clothing inspection should run through the whole process of cutting, sewing, keyhole nailing and ironing. Before the finished products are packaged and put into storage, they should be fully inspected to ensure the product quality.
The main contents of finished product inspection include: (1) whether the style is consistent with the confirmed sample. (2) Whether the dimensions and specifications meet the requirements of the process sheet and sample clothes. (3) Whether the sewing is correct and whether the sewing is neat and flat. (4) Check whether the plaid of the plaid fabric is correct. (5) Whether the thread of the fabric is correct, whether there are any defects or oil stains on the fabric. (6) Whether the same dress has color difference. (7) Whether the ironing is good. (8) Whether the adhesive lining is firm and whether there is glue leakage. (9) Whether the thread has been trimmed. (10) Whether the garment accessories are complete. (1 1) Whether the size marks, washing marks and trademarks on the clothing are consistent with the actual contents of the goods and whether the positions are correct. (12) Whether the overall shape of the clothing is good. (13) Whether the packaging meets the requirements.
(9) Packaging and storage
Clothing packaging can be divided into hanging packaging and box packaging, and box packaging is generally divided into inner packaging and outer packaging.
Inner packaging refers to putting one or more clothes into plastic bags. The model and size of the clothing should be consistent with those marked on the plastic bag, and the packaging should be flat and beautiful. Some special styles of clothes need special treatment when packaging. For example, wrinkled clothes should be wrapped in twisted rolls to maintain their styling style.
The outer packaging is generally packed in cartons, and the size and color are matched according to customer requirements or process orders. Generally, there are four packaging forms: mixed color code, monochrome code, monochrome code and mixed color code. Pay attention to the completeness of quantity and the accuracy of color and size when packaging. The outer box shall be marked with a container mark, indicating the customer, port of shipment, box number, quantity, place of origin, etc. , and the content is consistent with the actual goods.
