Polyester knitted fabric

Nantong Tongchunlong Textile Technology Co., Ltd. is well aware that the molecular structure of polyester fibers is the basis of their wrinkle resistance. The molecular chains of polyester are connected by ester groups to form a highly stable linear structure, which gives polyester fibers excellent rigidity and elastic recovery. In the fabric design stage, Tongchunlong carefully selects yarn specifications, warp and weft density, and tissue structure to optimize the wrinkle resistance of knitted fabrics.
Polyester fibers have excellent elastic recovery ability, which is an important basis for their wrinkle resistance. When polyester knitted fabrics are subjected to external forces, the fibers will deform to a certain extent. However, once the external force is removed, the polyester fibers can quickly return to their original form. This rapid elastic recovery ability allows polyester knitted fabrics to maintain good flatness and shape stability after multiple wearing and washing.
In knitted fabrics, the fibers are interwoven to form a mesh structure. Because the surface of polyester fibers is relatively smooth, the friction between fibers is relatively small, which to a certain extent reduces the wrinkles caused by fiber slippage. At the same time, through reasonable weaving process and structural design, the interaction between fibers can be further enhanced and the wrinkle resistance of knitted fabrics can be improved.
The heat resistance of polyester fiber is an important guarantee for its shape retention. Nantong Tongchunlong Textile Technology Co., Ltd. strictly controls the selection of raw materials to ensure that polyester fibers have good heat resistance and dimensional stability. During the processing, the heating temperature and time are controlled to avoid thermal shrinkage or deformation of the fibers, thereby maintaining the stability of the fabric shape.
Polyester fiber has excellent heat resistance and can maintain a stable shape at higher temperatures. This feature enables polyester knitted fabrics to maintain a stable shape and size during heat setting. Heat setting is a process that rearranges and fixes the fiber molecular chains by heating, which can effectively improve the shape retention of knitted fabrics.
Elastic modulus is a physical quantity that measures the material's ability to resist deformation. Polyester fiber has a high elastic modulus, which means that its deformation is relatively small when subjected to external force. This high elastic modulus enables polyester knitted fabrics to maintain good shape stability when subjected to external force and is not prone to permanent deformation.
The structure of knitted fabrics has an important influence on their shape retention properties. Reasonable structure design and tight weaving process can enhance the stability of the fabric structure and reduce deformation caused by external forces. For example, the use of high-density weaving process can increase the number of interlacing points between fibers and improve the tightness and stability of the fabric; while the use of a specific structure can enhance the elasticity and shape retention of the fabric.
In addition to the above-mentioned fiber and fabric structure factors, post-finishing process is also an important means to improve the shape retention properties of polyester knitted fabrics. The shape retention properties of polyester knitted fabrics can be further improved by post-finishing processes such as resin finishing and heat setting. Resin finishing is to coat a layer of resin film on the fiber surface to enhance the interaction between fibers through the cross-linking effect of the resin; while heat setting is to use high temperature to rearrange and fix the fiber molecular chains, thereby improving the morphological stability of the fabric.
