4 Requirements
4.1 Technical requirements of woven belts are divided into inherent quality and appearance quality. Inherent quality requirements include seven indexes: width deviation, weft direction density deviation ratio, thickness deviation, length deviation, colour fastness to perspiration, colour fastness to rubbing and colour fastness to light. Appearance quality requirements mainly include the appearance defects.
4.2 Inherent quality requirements of woven belts are detailed in Table 1.
