Abstract:
A warp knitted fabric, comprising:a base fabric having first threads, second threads and third threads, wherein the first threads are extended along a warp-wise orientation of the base fabric to form wales and are lapped to form crochets on the base fabric, the second threads are extended along the warp-wise orientation of the base fabric and are repeatedly and cross lapped over two of the wales and the third threads are extended along the warp-wise orientation of the base fabric and are repeatedly and cross lapped over two of the wales, wherein distances of the third threads lapped are greater than distances of the second threads lapped; wherein the base fabric has a rare portion, which is a region of the base fabric having less of the third threads than the other region thereof wherein the rare portion is arranged at between two of the wales and is extended along the warp-wise orientation of the base fabric; wherein the base fabric further has at least a fourth thread, which is made of a material with a well elasticity, wherein the fourth thread is extended along the warp-wise orientation of the base fabric and is cross lapped over two of the wales to form an elastic portion extended the warp-wise orientation of the base fabric, wherein the elastic portion has a well elasticity for tension and the elastic portion has a side overlapped with a portion of the base fabric on which the third threads are knitted to form an overlapped portion, which makes the elastic portion coupled with the base fabric firmly, and the overlapped portion has a width smaller than or substantially equal to a distance between two of the wales.
