What are the Quality Inspection Standards for Underwear?

Underwear quality inspection is a science. It is so large that there is a dedicated quality inspection department and a dedicated quality inspection company, which are employed by brands in factories to strictly supervise the factory quality and packaging of each style of underwear.

Our underwear factory, as a knitting OEM for major first-line brands, has an independent QC quality inspection department. It starts from the cutting process to check for leaks and fill in the gaps. After the underwear is sewn, it is inspected twice, and after the underwear is ironed and basically finalized, it is inspected a third time, found that the missing needle and broken pieces were returned to the front line for repair - after ironing, the fourth quality inspection was carried out, and then ironing was carried out again after the inspection. Randomly sample from the boxes for final inspection before leaving the factory, a batch of underwear undergoes at least four inspections from cutting to leaving the factory. The defect rate of underwear leaving the factory is less than 1%, which is well-known in the industry. This is our reputation for more than ten years, with quality as the foundation.

If the factory you cooperate with does not have quality inspection and cannot be meticulous, or you want to personally control the quality inspection process, you can consider starting from the following major aspects. It should be noted that quality inspection focuses on different categories of underwear. Inspection of goods can be based on random sampling methods such as randomly selecting five pieces per color and each size or randomly selecting a few pieces per box to conduct inspections in the following aspects:

1. Fabric inspection

Appearance inspection of fabric defects: drawn yarn, drawn strips, colored yarn, weft bias, stains, pilling, holes, etc. Check whether the printing is exposed, blurred, front-to-back adhesion, whether the color is full, whether the pattern is flat, whether there is color difference between the left and right sides of the same pair of pants, whether the printed fabric feels soft, etc.

2. Inspection of elastic bands

a. The quality of the elastic band: First, check whether the elastic band is dirty, drawn or other quality problems. Secondly, check the elasticity of the elastic band. For the good underwear, the elasticity of the elastic band must be strong. When we stretch it hard, the elastic band will not curl or become wavy when it rebounds. Furthermore, the elastic band must have an appropriate thickness. If the thickness is not enough, the band will slip. An elastic band that is too soft will not have enough elasticity.

b. The workmanship of the elastic band: whether the seams are flush, whether the seams are loose, and whether the leg opening of the pants is symmetrical.

3. Measurements inspection

Measuring one by one according to the bulk size chart, the measurements in the tolerance range are allowed (according to the tolerance range on the customer's size chart), but tolerances are inevitable and unavoidable.

4. Symmetry check

The length of the left and right sides seam, the left and right leg openings, the position and size of the front mid-part, etc. all need to be symmetrical.

5. Workmanship inspection

The needle stitches of each part should be smooth, neat and firm, and the tightness should be appropriate. There should be no broken threads, skipped threads, holes, reverse pleats, burrs, floating threads, poor joints, or thread ends larger than 1CM. The stitches should not be too dense or too sparse. The care label is not sewn on the pants. The care label is sewn to the word, the position of the washing-water mark and the sewing effect, etc. Most underwear is made by hand. A piece of underwear requires at least a dozen processes. Each process has a fixed line. Moreover, good underwear has a very regular line trend. If there are large and small needles, broken threads, and skipped stitches. If there are jumpers, large and small needles, broken threads, holes with thread ends, it can at least indicate that the workmanship is not very fine.

6. Ironing inspection

All parts should be ironed and flat, no yellowing/no laser/no water stains, and the threads should be completely removed.

7. Accessories inspection

Check whether the position of care labels, bows, buttons, etc. and the sewing effect are correct and there are no omissions.

8. Packaging inspection

Whether the stickers (size stickers, barcode stickers, trouser-shaped stickers, etc.) are correctly, whether the underwear is folded correctly and flat, the color order of the packaging, the number ratio, etc. must be packed in strict accordance with the packaging instructions.

Such comprehensive quality inspection can generally only be accomplished by a third-party quality inspection company designated by the brand. This is why brands that emphasize quality must cooperate with large factories. The factory quality is already a high-quality product that can withstand scrutiny.

Quality is the foundation for the long-term survival of a brand. The quality of our Unitex underwear is worthy of your trust.
