Military uniform production process

After fabric arrives at the factory, it undergoes quantity checking as well as inspection of its appearance and intrinsic quality. Only fabrics that meet production requirements are used. Before mass production, technical preparation is conducted, including the creation of process sheets, sample patterns, and sample garments. Production proceeds to the next stage only after the sample garments are confirmed by the client. Fabrics are cut and sewn into semi-finished products. Some woven fabrics, after being made into semi-finished products, may require further finishing processes according to special requirements, such as garment washing, sand washing, and wrinkling effects. Finally, after auxiliary processes like buttonhole and button sewing, and pressing, the products are inspected for quality and then packaged and stored.

Maintaining fabric quality is crucial for controlling the quality of the final product. By inspecting and measuring incoming fabric, the authenticity rate of the garments can be effectively improved. Fabric inspection includes two main aspects: appearance quality and intrinsic quality. Appearance inspection focuses on detecting defects such as damage, stains, weaving flaws, and color differences. Defects affecting appearance should be marked during inspection to avoid their use in cutting. Intrinsic quality mainly involves shrinkage rate, color fastness, and weight (mm, ounces). Accessories such as elastic bands, fusible interlinings, and zippers should also be inspected. Accessories that do not meet requirements are not used in production.

Before mass production, technical staff must complete the technical preparation work. Technical preparation includes creating process sheets, sample patterns, and sample garments. This preparation ensures smooth mass production and that the final product meets client requirements.

A process sheet is a guiding document in garment processing. It specifies detailed requirements for garment specifications, sewing, pressing, and packaging, as well as details like accessory matching and stitch density. All processing steps should strictly follow the requirements outlined in the process sheet.

Sample patterns must be accurate in size and complete in specification, with precise matching of contour lines. The pattern should indicate the garment style number, part, specification, grain direction, and quality requirements, and have a pattern composite stamp on relevant seams.

Before cutting, a layout diagram based on the sample pattern should be drawn. The basic principles for layout are "complete, reasonable, and economical." The main cutting process requirements are as follows:

1.During material dragging, check the quantity and avoid defects.

2.Different batches of dyed or sand-washed fabrics should be cut separately to prevent color differences on the same garment. For fabrics with color differences, color difference layout should be performed.

3.Ensure the fabric grain is straight and the grain direction of the garment pieces meets process requirements.

4.For striped or checkered fabrics, align and position the stripes or checks accurately in each layer to ensure continuity and symmetry on the garment.

5.Cutting should be precise with straight and smooth lines. The fabric layers should not be too thick, and cutting should not deviate from the fabric layers.

6.Cut according to the alignment marks on the sample pattern.

7.When using conical hole markings, ensure they do not affect the garment's appearance. After cutting, count and inspect the pieces, bundle them according to garment specifications, and attach tags with style numbers, parts, and specifications.

Sewing is the central process in garment manufacturing and can be classified into machine sewing and hand sewing, depending on the style and technique. Sewing is performed in an assembly line process.

Interfacing is commonly used in garment processing to simplify the sewing process, ensure uniform quality, prevent deformation and wrinkles, and contribute to garment shaping. Types of interfacing primarily include non-woven fabric, woven fabric, and knitted fabric. The choice of interfacing should match the garment fabric and area, with precise control of adhesive time, temperature, and pressure for optimal results.

Buttonholes and buttons in garments are usually processed by machines. Key points to consider for buttonholes include:

1.Correct positioning of buttonholes.

2.Matching the size of the buttonhole with the button's size and thickness.

3.Proper opening of buttonholes.

4.For stretchable (elastic) or very thin fabrics, consider reinforcing the buttonholes with additional fabric on the inner layer. Button sewing should correspond with the buttonhole position to avoid garment distortion or misalignment. Pay attention to the amount and strength of sewing threads used for buttons to prevent button detachment, and ensure sufficient thread winding for thick fabrics.

Pressing is a crucial step in garment processing, often summarized by the saying, "30% sewing, 70% pressing." Avoid the following issues:

1.Overheating or prolonged pressing causing gloss or scorching on the garment surface.

2.Small wrinkles or pressing defects on the garment surface.

3.Missed pressing areas.

Inspection should be carried out throughout the entire processing, and a comprehensive inspection of finished products is required before packaging and storage to ensure quality. The main contents of finished garment inspection include:

Whether the style matches the confirmed sample.

Compliance with the process sheet and sample garment requirements for size and specification.

Correctness of sewing and neatness of stitches.

For patterned fabrics, checking if patterns and stripes align correctly.

Fabric grain correctness, presence of defects, or stains.

Color differences within the same garment.

Quality of pressing.

Adhesion of interfacing and absence of adhesive seepage.

Cleanliness of thread ends.

Completeness of garment accessories.

Correctness of size labels, care labels, and trademarks, and their positioning on the garment.

Overall garment shape.

Compliance of packaging with requirements.

Garment packaging can be either hanging or boxed, with boxes typically having both inner and outer packaging.

Inner packaging involves placing one or several garments in a plastic bag, with the garment style number and size matching those indicated on the bag. The packaging should be neat and aesthetically pleasing. Special treatment may be required for certain styles, such as twist garments, which should be rolled to maintain their shape. Outer packaging usually involves paper boxes, which are packed according to client requirements or process sheet instructions, including size and color combinations. Packaging types include mixed color and size, single color and size, mixed color single size, and single color mixed size. Ensure accurate quantity, color, and size matching when packing. The outer box should have labels indicating the client, shipping port, box number, quantity, origin, etc., and the content should match the actual goods.
