4,Models and specifications of nylon cord fabric:
Model:1400dtex/1260D Specifications:vl,v2,strength of a single strand ≥105N
Model:1780dtex/1680D Specifications:v2,strength of a single strand ≥120N
Model:2100dtex/1890D Specifications:v3,strength of a single strand ≥262N
Note:To prevent counterfeit cord fabric, the buyers can choose the strength of cord fabric, whose price rises in proportion to its strength.
