Processing knowledge and cutting process of woven fabrics(1)

Basic knowledge of general woven garment processing.

Production process

Inbound inspection of fabric and auxiliary materials → technical preparation → cutting → sewing → locking and buttoning → ironing → garment inspection → packaging → storage or shipment.

After the fabric comes into the factory, it should be counted and inspected for appearance and internal quality, and only those that meet the production requirements can be put into production. Before mass production, technical preparations must first be made, including the development of process sheets and sample boards and the production of sample garments, which are confirmed by customers before entering the next production process. After the fabric is cut and sewn into semi-finished products, some woven fabrics are made into semi-finished products, according to the special process requirements, the finishing process must be carried out, such as garment washing, garment sand washing, wrinkle effect processing, etc., and finally through the locking eye nail buttoning auxiliary process and ironing process, and then packaged into the warehouse after passing the inspection.

Technical preparation

Before mass production, the technical preparation work before mass production should be done by the technical staff first. Technical preparation includes three elements: process list, sample making and sample garment production. Technical preparation is an important means to ensure that mass production goes smoothly and that the final product meets customer requirements.

The process sheet is a guiding document in garment processing, which puts forward detailed requirements on garment specifications, sewing, ironing, packaging, etc. The details of garment accessories matching, stitching density, etc. are also clarified, see Table 1-1. All processes in garment processing should be carried out with strict reference to the requirements of the process sheet.

Sample production requires accurate size and complete specifications. The relevant parts of the contour line accurately match. The sample should be marked with the garment model number, part, specification, silk skein direction and quality requirements, and the sample compound seal should be stamped at the relevant splice.

After completing the work of process sheet and sample board, the production of small batch of sample clothes can be carried out, and the discrepancies can be corrected in time according to the requirements of customers and process, and the difficult points of process can be tackled so that the large batch flowing operation can be carried out smoothly. The sample garment becomes one of the important inspection bases after the customer's confirmation and signature.

Before cutting, we need to draw out the material layout according to the sample, "complete, reasonable and economical" is the basic principle of material layout. In the cutting process, the main process requirements are as follows.

(1) When dragging the material, count the quantity and pay attention to avoid the defects.

(2) For different batches of dyed or sand-washed fabrics should be cut in batches to prevent color difference on the same garment. For a fabric in the phenomenon of color difference to carry out color difference row material.

(3) Pay attention to whether the silk skein of the fabric is straight and the direction of the silk strands of the garment is in accordance with the process requirements. For pile fabrics (such as velvet, velvet, corduroy, etc.), do not backwardly arrange the material, otherwise it will affect the color shades of the garment.

(4) For the striped fabric, pay attention to the alignment and positioning of the stripes in each layer to ensure the coherence and symmetry of the stripes on the garment.

(5) Cutting requires accurate knife, straight and smooth lines. The laying type should not be too thick, and the upper and lower layers of the fabric should not deviate from the knife.

(6) according to the sample alignment marks cut knife.

(7) The use of tapered hole markers should be careful not to affect the appearance of the finished garment. After cutting, count the quantity and check the piece of work, and according to the garment specifications in a pile bundle, attaching a ticket to indicate the model number, parts, specifications, etc.
