1- Checking input materials is the first important factor.

Concurrently, during the production process, the company’s technical team must always align the machine to measure the fabric evenly, avoiding different thicknesses and thinness in many areas. And must be present 100% of the time at the factory until completion.
In addition, at this step, the color must be checked to be uniform, not different from the color sample requested by the customer, and signed for approval from the beginning. The factory will have a team of experts in charge of color mixing and pre-sampling to get the formula before mass production in each company. After that, the quality must be updated every day and notified by QC (Quality Control) to superiors and related departments to promptly handle problems.
2- Check the material cutting stage.
At the step of checking the material cutting stage, there are some points to note as follows:
Must cut to the correct size and only have errors within the size allowed by the customer. The cutting diagram will be signed and approved by the leader and board of directors in each company before implementation. At this stage, the team leader ensures the correct cutting technique and detects errors at the raw material inspection stage if any are remaining to minimize errors in the production process.
3. Check each stage while sewing series
This is the most important stage since many details of quality arise during the sewing as:
- Printing on fabric: After the fabric is cut, it will be transferred to the printing department to print pictures, patterns, and logos on the fabric. Depending on the needs, the printed sample will respond as quickly as possible. The large, high-tech manufacturers often use modern printers and good ink quality to ensure the most perfect products.
- Assemble deviated machine parts.
- During the production process, the factory’s technical team must be regularly present to promptly adjust the amount of fabric produced evenly to avoid different thickness and thinness on a product, ensuring the right color for customers. And limiting errors on non-woven bags such as thread breakage, stitch removal, thread extrusion, edge deviation…
During sewing, every stage in the factory must always have QC to examine this work and limit 95% of finished goods prior error.
