Imitation silk in the structure of the fabric

(1) Density of fabric In order to achieve the effect of imitating silk, the density of the fabric is generally smaller than that of the same type of silk fabric, because polyester is relatively rigid and has a large twist shrinkage (generally, the shrinkage rate of silk George is about 17%. Simulated silk has a shrinkage rate of about 20% (the shrinkage rate is about 20%) and has a hard feel, so a smaller density is used to compensate. If the fabric needs to be treated with alkali weight reduction. Its density must also be increased or decreased taking into account the weight loss rate. The reduction in fabric density not only increases the breathability of the fabric, but also increases the elasticity of the fabric due to the increased freedom of thread sliding. However, the density cannot be too small, otherwise it will affect the inherent quality of the fabric (such as fatigue, etc.) The characteristics of silk threads are the same as those of real silk fabrics. Generally, the warp and weft are thin and thick. The thin silk threads can bend around the thick silk threads. In this way, the surface of the fabric is mostly composed of thin silk threads, resulting in a delicate appearance and full fabric.
(2) Fabric weave The performance and appearance of the fabric mainly depend on the weave of the fabric. Polyester simulated silk mainly adopts plain weave, some also adopt satin weave, and a small amount of crepe weave is used. (1) Plain weave: The plain weave has many intersecting points of warp and weft, so the fabric has a flat and dense appearance. Therefore, light and thin spun, crepe, arbor, and brocade fabrics all adopt plain weave. However, due to different fabric structures and processing methods, plain weave also has different appearance effects. (2) Satin weave: The appearance of the fabric is bright, smooth, and soft to the touch. (3) Crepe structure: The crepe effect can be obtained by two methods. One is to use the crepe structure, and the other is to twist and shrink the crepe threads, which have the appearance of evenly distributed particles around the surface of the tissue, but the excellent effect is not obvious. Generally, silk fabrics do not use crepe weave, but imitation silk fabrics use a small amount of crepe weave.
