What is the way to distinguish the quality of jacquard elastic bands when we purchase a new batch? Let's follow the editor and take a look!
Environmental pollution: According to the naked eye, there are dirt, coloring, oil stains, and other dirt on the tightness of the jacquard.
Color deviation detection: This can be visually inspected by observing its color, texture, and needle edges. It should not be disorderly and should be a very pure color.
Burr: Generally, it is a burr on some cotton yarn, which can also be observed with the naked eye. The double-sided and overlock seams of the ribbon should not have serious yarn balls or filaments.
Needle detachment: This can also be observed with the naked eye, and the jacquard elastic belt cannot have needle detachment;
The quality of the ribbon is undoubtedly related to the specifications and models of the ribbon, and standardized specifications and models are the best reflection of the quality of the ribbon.
Thickness inspection: Measure accurately with a micrometer accurate to 0.001, and the dimensional tolerance should not exceed the positive and negative poles by 0 millimeters.
Overall width inspection: Use a vernier caliper to accurately measure the total width of jacquard strips 1 inch and above, with a dimensional tolerance of no more than 0.25 points between the positive and negative poles; The standard tolerance for the total width of webbing 1 inch and below cannot exceed the positive and negative poles by 0.25mm. Note: Plain fabric and herringbone straps must have sufficient specifications and cannot exceed 0.25 points.
