The first step of the operation is not from the selection of materials or cutting. After receiving the original sample of leggings or making a drawing, a detailed plan should be made. First of all, it is necessary to analyze the sample and the attention points in order operation, confirm the size, and sort out the use of main and auxiliary materials of each color.
The first is the specification table, specification table can be divided into a sample specification table, approval sample specification table, prenatal specification table.
This specification table is mainly used for designers to see the effect of style and calculate the material used in production. Under normal circumstances with similar cloth proofing, allow auxiliary materials to substitute. For production factory, the specification is just for quotation, so that to be a real order, each project should be paid attention to when applying the form, content and specification, because the content and specifications often, costs directly associated with any is beneficial to reduce the cost without changing the original clothing can be collected the basic requirement of methods and Suggestions are lots. All changes in this specification sheet must be commented so that the next work can be carried out accordingly. In addition, approval sample this specification sheet is mainly used for approval sample. Before making approved samples, operate item by item according to the provided style and specific requirements in the sample specification table, check the fabric structure and structural specifications of samples, measure all sizes, make sure that the size of each point is within the allowable error range. Send the pattern and specification sheet to the relevant technical personnel to review all the difficulties in order to fully understand the condition of the sample. In principle, formal main materials and auxiliary materials are used for making approved samples. In addition, this specification sheet is mainly provided by the customer after the approval sample is approved by the customer. Only this product specification sheet can be used by the factory for mass production. If replace with the specifications of the table before, often mistake, because after proofing, customers often change the size of the original, and the size of the changes tend to be small, before a large number of production and operation, must also make a sample, known as pp samples, in making this sample, after all the main material and accessories must be used to be used in production, Customers can be opened in large numbers after full approval.
Ii. Specific operation of leggings production:
The basic technological process of leggings production includes eight processes, such as incoming inspection of fabric materials, layout, cutting, sewing, keyhole nailing, ironing, garment inspection, packing and warehousing.
Material inspection and testing: including color deviation inspection, dimensional deviation and defect inspection. After the cloth into the factory to count the quantity and appearance and internal quality inspection, in line with the production requirements can be put into use. The quality control of fabric is an important part of the quality control of finished products. Through the inspection and measurement of incoming fabric, the rate of genuine garment can be effectively increased. Material inspection includes shrinkage of elastic band, bonding fastness of fusing lining, smoothness of zipper and so on. Materials that cannot meet the requirements shall not be put into operation.
Next comes the technical preparation: technical preparation is an important means to ensure that mass production goes smoothly and the final product meets customer requirements. Before mass production, the technical preparation before production should be done first by the technical personnel. Technical preparation includes process sheet, sample making and sample making. Process sheet is a guiding document in garment processing. It puts forward detailed requirements for garment specifications, sewing, ironing, packaging, etc. It also clarifies details such as garment accessories collocation and stitch density. Each process in garment processing should be carried out in strict accordance with the requirements of the process sheet. Sample production requirements accurate size, complete specifications. The contours of relevant parts were accurately matched. The garment model number, position, specification and quality requirements shall be indicated on the sample, and the composite seal shall be affixed at the relevant stitching place. After the completion of the process sheet and sample work, can carry out the production of small batch sample clothes, according to the requirements of customers and process timely correction of non-conformance points, and to solve the difficulties of the process, so that the mass flow operation smoothly. The sample becomes one of the important inspection basis after the customer confirms and signs.
Discharge: 1:10 pre-shrink discharge, according to the sample drawing discharge chart, “complete, reasonable, saving” is the basic principle of discharge.
Cutting: each auxiliary material and cutting once called a bed or a knife, cutting bed can improve production efficiency, relative saving of raw materials, more than manual cutting to ensure quality, general cutting layers less cost is higher. (The picture above shows the cutting order in the factory)
Sewing: stitch and stitch type are the basic elements of stitching. Clothing sewing can be divided into machine sewing and manual sewing according to style and craft style. Assembly line operation is carried out in the sewing process. Process analysis chart during sewing.
III. Later process:
Keyhole nail button: the keyhole and nail button in leggings are usually processed by the machine. The buttonhole can be divided into flat and eye holes according to its shape, commonly known as sleep hole and a pigeon eye hole. The soulful is mostly used in shirts, skirts, pants and other thin clothing products. Pigeon eye holes are mostly used for coats, suits and other thick fabrics.
Clothing ironing: the role of ironing is to use spray ironing to make the clothing pre-shrink, make the clothes beautiful appearance, change the expansion of the material, plastic. The size of the liner plate is slightly larger than the size required by the garment, so as to prevent the specification from being too small after shrinkage. The ironing temperature is generally controlled between 180℃ and 200℃, which is relatively safe and not easy to yellow and coking.
Clothing inspection: leggings will face consumers directly, so the inspection before leaving the factory plays a pivotal role. As there are many factors affecting the quality of garment inspection, garment inspection is an important link in the management chain of garment enterprises. The correct inspection view is very important. Quality inspection refers to the measurement, inspection, test and measurement of one or more characteristics of products or services by some method, and the comparison of these measurement results with evaluation standards to determine the merits of each product or service, as well as the batch of products or services qualified or not. Compared with the required quality, the nature of the products produced will be uneven, there is a certain gap. For this gap, inspectors need to determine whether the product is qualified or not according to certain standards. The standard usually implemented is: the gap within the allowable range is judged as qualified products; The gap beyond the allowable range is judged as unqualified.
Finished packing: the packing of leggings can be divided into two kinds: hanging packing and box packing. Carton packing is generally divided into inner packing and outer packing. Inner packing means that one or more garments are put into a plastic bag. The garment size and size should be consistent with those indicated on the plastic bag. The packaging should be smooth and beautiful. For example, twisted and wrinkled clothing should be wrapped in a twisted roll form to maintain its style. The outer packaging is usually packed in cartons, and the size and color are matched according to customer requirements or process instructions. Packaging forms generally has a mixed color mixed code, single color alone code, single color mixed code, mixed color alone code for.
The above three parts constitute the main production process of a garment factory. Good products factory not only rely on the support of hardware equipment, the most important or rely on its own a good management system, so as to make all processes orderly, improve the economic benefits of enterprises. Produce high quality and qualified leggings.
