How to improve the dimensional stability of polyester-viscose elastic dyed suit fabrics?
The dimensional stability of polyester-viscose elastic dyed suit fabric is one of the important indicators for evaluating its quality. Dimensionally unstable suits are prone to deformation during wearing and washing, affecting the appearance and wearing experience. The following will introduce in detail several methods to improve the dimensional stability of polyester-viscose elastic dyed suit fabrics.
1. Optimize the selection of raw materials and blending ratio
The dimensional stability of polyester-viscose blended fabrics is closely related to the selection of raw materials and the blending ratio. Polyester fiber plays a key role in maintaining the dimensional stability of fabrics due to its high strength, high modulus and excellent elastic recovery. At the same time, the addition of viscose fiber can improve the moisture absorption and breathability of fabrics. By adjusting the blending ratio of polyester and viscose, a balance point can be found to maintain the excellent performance of polyester and improve the comfort and dimensional stability of fabrics.
2. Use advanced weaving technology
The weaving process has a significant effect on the dimensional stability of polyester-viscose elastic dyed suit fabrics. The use of high-density weaving can increase the tightness and stability of the fabric. At the same time, reasonable warp and weft density and organizational structure can also effectively improve the dimensional stability of the fabric.
3. Application of finishing technology
Finishing technology is an important link in improving the dimensional stability of fabrics. For example, through heat setting treatment, the internal stress of the fiber can be released, reducing the possibility of subsequent deformation. In addition, the use of special coating technology can also enhance the stability of the fabric to a certain extent.
4. Reasonable dyeing and finishing process
The dyeing and finishing process also affects the dimensional stability of the fabric. Selecting suitable dyes and auxiliaries, as well as controlling parameters such as temperature, time and pH value during dyeing and finishing, can reduce the deformation of the fabric during the treatment process. In particular, elastic dyeing technology can improve dimensional stability while maintaining the elasticity of the fabric.
5. Quality control and testing
Strict quality control and testing are also the key to ensuring the dimensional stability of the fabric. During the production process, dimensional stability tests should be carried out regularly to detect problems in time and make adjustments. This includes testing multiple indicators such as fabric shrinkage, stretch recovery, etc.
Through the above methods, the dimensional stability of polyester-viscose elastic dyed suit fabrics can be effectively improved, thereby meeting consumers' demand for high-quality suits. The implementation of these measures requires fabric manufacturers to have advanced technology and equipment, as well as a keen insight into market dynamics and consumer needs.
