3.1 The polyester fiber used for standard bleached polyester fabric has a fineness of 1.5 dtex, a length of 38 mm, semi-dullness, round cross-section, and the original yarn count is 13 tex.
3.2 Width: 110-2cm
3.3 Density: 410-8 strands/10cm in warp
360-7 strands/10cm in weft
3.4 ​​pH value: 7±0.5
3.5 Whiteness: 75±5
3.6 Dyeing effect: The color difference between batches of standard bleached polyester fabrics, dyed with the same dye and the same method, is "similar" to "slight", and the change in color depth is no more than ±5%. 4 Grading regulations
4.1 Standard bleached polyester fabrics are graded into qualified products and unqualified products. The grading is based on the combination of internal quality and appearance quality. The internal quality is graded by criticism, with three consecutive shifts as a batch, and the appearance quality is graded by matching. The lowest rating of internal quality and appearance quality is used as the final grading.
