Appearance defect weft table inspection method
(reference)
The method specified in this appendix is ​​used as a temporary transitional inspection method when the warp inspection conditions are not fully met at present; as an inspection method for silk fabrics below 52 g/m2.
Inspection method
A2.1 Place the fabric on the inspection table in a folded shape and conduct weft inspection. A2.2 Inspection conditions
The inspection table is 0.95m high and the table surface is black to avoid sunlight and white reflection; b. Natural north light, with an average illumination of 320 to 500ix, c. Inspection speed is 15 pages/min.
A2.3 The inspector is located in front of the inspection table, with his eyes about 60cm away from the center of the silk surface. A2.4 Products with a width of 114cm or less shall be inspected by one person, and products with a width of more than 114cm shall be inspected by two people. A2.5 Appearance defects shall be based on the flat front of the silk surface, and the size of the sag point shall be measured in the maximum direction of the warp or weft. Additional remarks:
