Quality Control - YULONG SAFETY


In order to ensure 100% ex fabric factory pass rate ,we produce according to the production technology strictly in production process.For example:concentration of chemical additives,liquid entrainment rate,speed of fabric production equipment operation, moisture content time of neutralization, all must be strictly controlled within a reasonable range during the production process.We need to do correlation detection about each 1000 meters of the functional finishing fabric before stentering.We do 10 detection in each 1000 meters:we will do 3 detection near the test area if there is 1 disqualification,and if it is unqualified again,we will return all the fabric to fix or scrap.


We have an excellent and complete workwear inspection process to ensure that all the garment we produced will achieve customer’s

  • We will inspect fabrics and accessories before the workwear production to ensure the quality of the materials we use can arrive the standard.

  • We arrange flow testing staffs to inspect the thickness of thread,the size of the needle,needle pitch,single stitch,double stitch,triple stitch,eyelet,fell seam and thread ect seriously.

  • We will arrange professional quality inspectors to text the firmness of workwear after finishing the garments,for example:the inspectors will test whether there are double stitch,triple stitch,and bar-tacking to reinforce the pockets,pocket flaps,trouser loops and other position of stress intensity.Once they find problem, QC will ask workers fix it.

  • We will do final Random Inspection before delivery,so that we can ensure that every batch of the production will be qualified 100%.
