Some rules for identifying appearance defects of glass yarn

(1) Any appearance defects with different names and different degrees close to the glass yarn should be deducted separately, but if they are mixed together, points will be deducted according to seriousness.

(2) Within the specified length of the glass yarn, points will be deducted based on the number of defects and the locations will be carefully selected.
(3) All defects with points deducted based on length will be calculated based on the maximum length.
(4) When measuring the length of intermittent or scattered defects on glass yarn, if the distance is 1 cm or less, measure the entire length. If the distance is greater than 1 cm, measure the lengths separately.
(5) Defects such as debris and drag must be repaired. If the repair is poor, points will be deducted according to similar defects.
(6) The false cutting area should be clearly marked, regardless of the production value, and the starting point for production deduction is 10 centimeters. The length of false cutting at one time shall not exceed 3 meters, and the length of false cutting shall not exceed 3 meters. When the interval between two false cuts is less than 1 meter, the interval will not be counted in the production value.
(7) No points will be deducted for wrong warp, loose warp, double warp, wrong warp, warp, continued shrinkage and displacement within 1 cm from the Fiber Glass.
(8) If a defect is deducted 5 points, it can be treated as false cutting.
(9) Defects in the Fiber Glass that are not regulated in this specification can be deducted according to similar defects.
