1: color difference: including whether there is side color difference, horse difference and cylinder difference. How much is the difference from the samples confirmed by customers before?
2. Color fastness: be sure to soak in hot water and washing powder to see if it fades.
3. Width: Measure whether the width is the same as the specified width. If there is any difference, you must discuss it with the guests or the clothing factory, because the difference in width will cause cutting waste.
4. Gram weight: Measure the actual gram weight with a gram weight machine. Under normal circumstances, it should be about 5g lighter than the specified weight.
As for other aspects, it is nothing more than looking at how many flaws and holes there are in the fabric.
Basic knowledge of clothing quality inspection
First, the specifications do not match.
Causes of serial number defects
1, specifications are out of tolerance-samples are not allowed; Cutting is not allowed; When quilting, the seam position is out of tolerance.
Second, sewing is not good.
2. The needle distance is out of tolerance-the needle distance is not adjusted strictly according to the process requirements when sewing.
3. Needle skipping-Discontinuity due to mechanical failure.
4. Off-line-when the needle is lifted and dropped, the needle is not returned; Or the floating line is serious.
5, needle leakage-needle leakage due to negligence; Get down when sewing.
6. Gross leakage-the edge copying machine fails or misses copying; The refraction of raw edges is not tight, the bag digging technology is not enough, and the bag corners are hairy.
7. Floating line-the soap bubble is too loose, or the line pressing plate is too tight.
8, floating bottom line-the line pressing plate is too loose, or the shuttle is too tight.
9. Sewing back-poor sewing skills, not spitting seam according to process requirements.

1 1. Wrinkling-The needle and thread were not replaced according to the thickness of the sewn piece; Or that sew article has a length.
12, button lifting-button closing due to insufficient technology; The stitches don't match
13. Double-track-check a single open line. After disconnection, the suture is not on the original stitch; After sewing the lower sill of the patch, two stitches were caused when sewing the line.
14, the two lines are not parallel-because of insufficient technology; Or careless operation causes uneven width of double lines.
15, not straight-uneven seam position leads to non-straight seam stop; Technical error detection line bending.
16, uneven clothing-the seams on the surface are not straight and uneven; Inconsistent joints; The upper and lower pieces are not elastic.
17, not square-the corner, bottom edge, swing angle and square collar of the bag are not sewn at 90 degrees.
18, not round-round neck, round pocket corner, round sleeve head, round pendulum of suit, because the sewing technology is not up to standard, there are small edges and corners.
19, asymmetry-due to poor technology or careless operation, errors such as length, height, fat and width occur in the parts that must be symmetrical.
20. Uneven eating potential-after the sleeves are put on, the sleeves are chubby or have fine folds due to uneven eating potential.
2 1. Skew position-there are less than three sleeves, collars and positioning points, or the positioning is inaccurate.
22, the article, the grid is not allowed-when cutting, there is no clear cutting position; Or the layout is not strictly aligned with the grid; When sewing, it was sloppy and didn't align with the grid.
23. Up and down-the sewing technique is low or the operation is sloppy, and the sewing line is not always at the edge.
24. The pinhole is exposed-the pinhole at the edge of the cloth is not removed when cutting; Hole removal is not included during rework.
25, the collar angle starts from the beans-the sewing technology is low; The cleaning and shearing at the coupling do not meet the requirements; The folding process does not meet the requirements; Not crushed by the collar setting machine.
26. Incorrect location of spare parts —— When sewing, spare parts were not sewn according to the sample clothes or process sheets.
27. Mark dislocation-the main mark and washing mark are not sewn according to the requirements of sample clothes or process sheets.
Third, stains.
28. Handwriting-illegal use of pens or ballpoint pens to prepare cutting numbers, work numbers and inspection numbers.
29. Oil pollution-the machine leaks oil when sewing; Eat greasy food in the workshop.

33. Watermark-the stain on the seam of dyed cloth stained with water.
34. Rust-metal buttons, zippers and belt buckles are of poor quality and stick to the seams after rusting.
Fourth, ironing
35, blanching discoloration-iron temperature is too high, make fabric blanching discoloration (especially chemical fiber fabric).
36. Aurora-there is no steam ironing, and the electric iron is not padded with water cloth, resulting in local light.
37, dead mark-the hot surface is not smooth, burning out irreversible folds.
38. Work carelessly due to heat leakage, and there is no overheating in a large area.
V. Threads
39, dead line-not clean after trimming and pruning.

42, do the reverse cloth-sewing workers will not recognize the front and back, so the cloth is reversed.
43. Cutting pieces are in the same direction-due to cutting and layout errors, symmetrical cutting pieces are cut in one direction.
44. Defects are out of tolerance-there are many defects in the fabric, which are not eliminated during the layout, resulting in more than the allowable number of defects in important parts and secondary parts.
45. Incorrect buckle-uneven height of the buckle plate or incorrect buckle.
46, buttonhole askew-buttonhole operator careless operation, did not straighten clothes, resulting in uneven buttonhole, not firm, not straight.

5 1, glue penetration-poor quality of adhesive lining; The viscose turns yellow, and the iron temperature is too high, which makes the fabric yellow.
