4 Point System for QC on Fabric

Fabric rolls for inspectionInspecting garments is tricky business. You must be sure to measure sizes, check material weight and composition, and of course check for cosmetic defects. Cosmetic defects on clothing are numerous: from missing buttons, to split seams to holes. But checking fabric rolls should be easy then, right? There are not as many possible defects and measurements are easier, right? Actually, this is incorrect; Making QC on fabric rolls is very challenging and requires precise methods. The inspector must check conformity; for example are the rolls the right fabric, colors and feel, the right length and packed properly?

Beyond these simpler checks, two industry methods used are the Ten point and Four point systems. The most commonly used is the Four point system. Within this system, fabric rolls are graded for defects. Each defect receives a certain number of points, and after inspection, of course you hope for the lowest number of points possible. The point system is as follows:

Four points fabric defect table

As you can see, the more severe the defect, the more points that will be taken off. It is up to the client to set the maximum number of defects per 100 yards, which is a maximum of 30 points per 100. The inspector will add up the defects points and then use the following formula to determine the rate of points per 100 yards.


After finding the stats for the individual rolls, the client is given:

  • Average points of all rolls sampled
  • Proportion of rolls above limit

Generally, an inspection company can check 1000 yards at most during one day, so if an average roll is 50 yards, that would mean 20 rolls inspected, which is what the proportion would be out of. Inspecting fabric is quite time-intensive and requires significant expertise. In discussing with your QC agents your textile requirements, you can choose the best acceptable limit of points to ensure that you will receive a shipment of good quality.

    • @snruvi: thanks for your question. An example is also a very good way to learn about it. We should publish a case study in the future. Keep an eye on the Quality Control Blog until then! ;)

  1. how about if we found continuous warp defect, shall we give point to the defect?
    warp defect such as : continuous line defect, ink stain/hole in every 30yds in fixed position

    • @yuliana Lenny: thank you for your comment and question! Any defect such as stain, holes should be included in the point system. In the case of the warp defect: if it is less than 3 yards, we should deduct points according to the warp defect length. If it is more than 3 yards, the roll inspection is considered as failed. The QC should then put a remark explaining his decision.

  2. May I have a question. If factory find 17 point of defected while maximum of 30 points per 100 sq yds. Does supplier have to replace for them?

    • @Chuc Nguyen: Thanks for your interest and rising this question. Even if the number of points is lower than the maximum tolerated the buyer is in right to consider those points as unacceptable. However, to avoid misunderstandings, it is recommended that the buyer precisely mentions what is acceptable or not acceptable in the purchase order.
      The supplier is free to decide if replacing those rolls or not, however if his objective is to keep the business relationship with you, he may accept. Sometimes they also ask for a financial support from buyers’ side, a negociation process is put in place.
      To keep the situation under control, the best is use a proper payment terms, linked to the inspection result, i.e.: full payment after approval of the inspection result (you may only loose the deposit if applicable).

        • @Chuc Nguyen: Thanks again for your interest and comments. Please don’t hesitate to ask any question, we would be glad to discuss upon QC topics! And we also invite you to share your experiences on this Quality Control Blog.

      • Can you more explain to me, if we factory found as above point and they need replenish fabric percentage so how we know the percentage that we’ll replenish to them. Some time they confuse about point and percentage that 15 point become to 15%? Also supplier will not accept 15 point to 15%.

        • @Morkat: as a factory you are supposed to control all rolls and determine the amount of work to be done. However, in the future, it is highly recommended to implement a good quality management system in the factory, it includes a good internal quality control during the production. This way you will work in order to make sure the inspection result will be pass and you won’t have to rework the goods which cost money and time. Quality assurance is more efficient and cost effective. Learn more about quality management system: http://www.asiaqualityfocus.com/blog/supplier-quality-management-system-selections-criteria/

    • @usama: Thank you for your question. The kgs per roll varies a lot depending on the material, the roll width and length.
