when making pattern, we should consider the shrinkage rate of the above < a href= "//www.sjfzxm.com/" target= "_blank" > leather < /a >. The process of leather finishing to cut leather may be incomplete due to the short time, and the leather parts cut according to the pattern will shrink and deform. In addition, ironing is required in the final stage of finishing, so cold shrinkage will also occur after the leather is cut. In addition, the material of the curved part is easier to elongate, so the addition of the sleeves and collar should be slightly less than that of the fiber products. < a href= "//www.sjfzxm.com/news/index_c.asp > > leather cutting > /a >. 
 (1) the fibers of the leather are interwoven in a certain direction, so the tensile strength and elongation of the fibers are small, and the tensile strength perpendicular to the fiber direction is small and the elongation is large. We should consider the direction of leather fiber and other factors in the pattern arrangement. We should consider the direction of weaving of leather fibers and avoid the deformation of products after washing. 
 (2) the consistency of leather surface is poor, there are disability, different grain lines, colored flowers and so on. Before cutting, it is necessary to take a serious look at the parts of the severely disabled parts, and try to make the pattern avoid these parts for discharging. 
 (3) when the general samples are cut, a number of leather methods should be used. The leather should be selected before the material is cut, and the leather with similar color will be classified into a set. 
 (4) when making leather < a href= "//www.sjfzxm.com/" target= "_blank" > clothing < /a >, in order to avoid the elongation of leather, the size of the product parts is usually added to L and 2cm to coarsely cut, and the leather parts are pressed at 120 degree temperature, and the size of the leather parts tends to be stable after thermal expansion. The pressed leather parts can be placed for about 10 minutes to achieve a stable size. Raw material characteristics and cutting technology application of leather fabric clothing 
 leather garments are mainly made from sheep leather, goat leather, cow leather, and some other rare animal skins, such as deer leather, kangaroo leather, etc. 
 > a href= "//www.sjfzxm.com/news/" > sheep leather > /a >: fine grain, soft handle, elongation, breathability and gloss, and high-grade sheep leather has a special sense of silk. 
 cattle leather: the fibers are tightly woven, high strength, smooth and fine grain, and good physical properties. 
 no matter which material is used for clothing leather, the unit area is required to be light in weight, loose in fiber and properly dispersed, and at the same time, it has a certain elongation rate. The leather is full and soft, with little color difference and good physical and mechanical strength. Within the range of available area, the positive garment leather shall not be wrinkled, cracked, loose, colored, uncovered, or disabled. 
 the layout of the leather garment, the cutting and cutting of the leather, often use the symmetry method, that is, the leather's back line is bounded, the left and right row is arranged and the bottom is cut. Leather clothing tailoring, because its fabric is a piece of animal prototype leather, moreover, the size of the skin itself, thickness, disability is not the same. Before cutting, it is necessary to match the color, grain size, thickness, hardness and color of the animals according to the size, style and variety of the garment. In addition, the skin injury should be marked with chalk, according to the material area (i.e. unit consumption) stipulated by the process, and according to the regulations, the unit consumption should be matched with 1 to 2 sheets of skin. A leather garment requires a few or more than ten pieces of leather, like a suit coat, which needs about 4 sheep leather. 
After P, leather is typesetting. Layout is a very important process. It must be calculated and arranged, rather than quota. Whether the structure of the garment is reasonable is to see whether the primary and secondary parts of the leather are properly distributed in the main and minor parts of < a href= "//www.sjfzxm.com/" target= "_blank" > clothes < /a >. For example, the central part of the leather is corresponding to the main parts of the garment, such as the middle, the front, the middle, the big, the collar, the welt (etc.). The minor parts of the leather clothing correspond to the minor parts of the garment, such as the front armpits, the armpits, the small sleeves, the collar, the welt, etc. < a href= "//www.sjfzxm.com" > leather clothing < /a > different from woven fabrics, the remaining leather is different and can be used on another garment, so the consumption should be reduced to the minimum to reduce the cost.
