The earliest ropes were mainly used for fixing. In primitive society, there were no needles and threads. Animal skins worn by humans can only be fixed with ropes to achieve the purpose of taking them. Nowadays, rope belts have two main functions in clothing, one is for decoration, to decorate and embellish, or to emphasize logo; the other is for fixing and connecting garment pieces to meet the basic purpose of taking. With the improvement of people’s living standards and the development of science and technology, people’s clothing has developed in a diversified trend, and ropes and belts appear more and more frequently in different styles of clothing, becoming an important design element of clothing styles.

The cords are made of elastic cotton cords, hemp cords, leather cords, ribbons, jacquard webbing, jacquard cords, jacquard moldings, ethnic flower belts, various types of elastic cords, molding webbing, decorative color strips, knitted edging tapes , Nylon rope, colored yarn rope, lace belt, buckle bag, water wave belt and other varieties, organic weaving, knitting and knitting technology. In the down jacket design, the ropes play a role of fastening and closing, achieving the purpose of decoration and practicality.

According to the purpose of taking, the decorative effect of the drawstring has little effect on the down jacket model design. Many clothing fit designs can also be decorated with ropes. Its purpose is only for decoration; if it is used to tighten the waist , The clothes are required to be loose, and to achieve the purpose of fit through the tether belt, then this method will have a certain impact on the design of the model. The number of changes in the model specifications depends on the length of the cord.

The shrinkage rate of the draw-stitching process leads to minimal changes in the length of the sample size and a large change in width, which depends on the length and elasticity of the elasticity. When applied to down jackets, the draw-stitching process mainly affects the size in the same direction as the direction of the elasticity. Larger, in the design process of the down jacket model, the change in shrinkage caused by the length and elasticity of the elastic should be considered.
