Industrial layout is aimed at mass production of clothing, aiming at the appearance characteristics of clothing, ensuring the specifications and quality of cut pieces and saving raw materials. Therefore, it is an important process with high technical content in garment production. Let's learn the technology and craft of garment typesetting together!
1. Circuit board layout technology
In any typesetting case, samples must be drawn according to the size of the samples, because the samples made by the sample engineering department have undergone strict inspection and audit. Among them, various factors that may affect specifications and dimensions, including shrinkage and seams, have been carefully considered, which is the main basis of industrial drawing. Therefore, the shape and specifications of the drawings should be consistent with the intention of sample making.
2. Symmetrical layout technology of garment pieces
Clothing pieces are basically symmetrical, such as left and right front pieces, sleeve pieces, left and right pants pieces, etc. When making patterns, these symmetrical pieces usually draw only one pattern. Pay special attention to the front and back of a sample when laying out, so as to ensure that the cut piece is symmetrical. And pay attention to avoid leakage.
3. Precise line technology
Clothes should be close to each other. Without affecting the specifications and cutting quality, sometimes two pieces can share a line (usually a straight line), and cutting with one knife can save drawing a line and cutting a line, thus improving the efficiency of discharging and cutting cloth.
4. Nesting and drawing technology
Make full use of the shape of the pattern and the width of the fabric to arrange the pattern reasonably, thus saving materials and reducing costs.
The patterns of the garment pieces are large and small, and the edge shapes are different, including straight, oblique, square, round, concave, convex, long and short. When typesetting, the details should be arranged first, and then the samples should be arranged later, so that the gap between large samples can be fully utilized and small samples can be discharged; Secondly, when discharging, the straight edge of the template should be aligned with the straight edge, the bevel edge should be aligned with the bevel edge, and the flange should be aligned with the notch, so that the templates can be closely arranged with each other to reduce gaps; Thirdly, if the templates can't be closely nested and gaps inevitably appear, the gaps of the two templates can be merged to increase the gap, and then discharged into other small templates in the gap; Fourthly, the size and specifications of the garment pieces can match the layout, and they can "learn from each other's strengths" to effectively improve the utilization rate of fabrics.
5. Fabric texture orientation technology
Many fabrics, such as woven fabrics and knitted fabrics, have different properties in warp, weft and diagonal directions. Generally, the warp tensile deformation is small, the weft tensile deformation is large, and the diagonal direction is large. Different clothing styles or clothing parts can be divided into straight materials, horizontal materials and oblique materials according to design requirements and dress comfort requirements. Therefore, in the clothing pattern, each piece of clothing must indicate the warp direction, so that the layout personnel can have a clear technical basis.
When making patterns, the warp and weft directions must be accurate. Before making a pattern, the warp, weft and diagonal directions specified in the pattern must be clearly determined. The yarn direction of the pattern is related to the product structure and surface shape. Therefore, no matter how the pattern is drawn, you can't change the warp, weft and diagonal directions at will.
