Textile Materials: Fabrics (14): Dimensional Stability of Fabrics
Many people have misunderstandings or do not understand “Textile Materials: Fabrics (14): Dimensional Stability of Fabrics“. Let me take you with me to share it with your friends. , explore knowledge about “Textile Materials: Fabrics (14): Dimensional Stability of Fabrics“…
The dimensional stability of a fabric refers to the fabric’s ability to resist dimensional changes after being soaked or washed and subjected to higher temperatures.
1. Shrinkage of fabric
After the fabric is soaked at room temperature or washed and dried, the length and width of the fabric shrink is called shrinkage, or “shrinkage” for short. Fabrics that absorb moisture from their fibers will shrink.
Main factors affecting fabric shrinkage:
The hygroscopicity of fibers is a direct factor in fabric shrinkage.
The tightness of the yarn and fabric structure is an indirect factor in shrinkage. The tighter the structure, the expansion of the fiber will cause the yarn to expand, and the buckling wave height of the yarn in the fabric will increase. The length of the yarn will become shorter in the buckling state, so the fabric will shrink. Therefore, the greater the twist and volume fraction of the spun yarn, the greater the fabric shrinkage.
Fabric finishing tension also has an impact on fabric shrinkage. If the finishing tension increases, the fiber deformation increases, the internal stress and slow elastic deformation increase, and the relaxation and retraction of the fabric after being soaked in water will significantly increase the shrinkage of the fabric.
Temperature also has a great influence on the shrinkage of fabrics, because heat has the effect of relaxation and expansion, and even thermal shrinkage.
2. Uneven shrinkage and distortion of fabric
The shrinkage performance of the fabric in the warp and weft directions or in local areas under normal conditions or after the action of heat and moisture is called the non-uniformity of fabric shrinkage. Anisotropic shrinkage is not a defect of the fabric, but uneven local areas and fabric distortion are quality defects of the fabric, which seriously affect the appearance of the fabric.
