4 Product Categories
Polyester dipped cord fabric is divided into high modulus low shrinkage type (HMLS), high strength high modulus low shrinkage type (HT-
HMLS) and high dimensional stability high modulus low shrinkage type (HDS-HMLS). According to the linear density and number of strands of its warp, it can be divided into
1100dtex/2, 1440dtex/2, 1670dtex/2, 2200dtex/2, 1440dtex/3, 1670dtex/3 and 2200dtex/3.
Each type of polyester dipped cord fabric can be divided into various specifications according to the different warp density. The commonly used organization specifications are shown in Table 1.
