Inspection method of clothing lining


The inspection method of clothing lining can refer to the inspection method of clothing fabric. Different clothing has different performance requirements for lining. The lining of different fibers has different physical properties, and the performance of the lining has a greater impact on clothing.


Washing shrinkage: The dimensional stability of synthetic fibers is good, and the shrinkage rate is small; the shrinkage rate of polyester and nylon lining is less than 1%; the shrinkage rate of regenerated cellulose fibers is about 2% to 4%.

Ironing shrinkage: The fiber material is different. After ironing and after a certain period of time, the shrinkage of the lining will change. If the shrinkage of polyester is small after ironing, the aging change is not large.

Frayed off-line: Polyester lining and acetate fiber lining are not easy to take off, while nylon and viscose lining are easy to take off. In addition to the fiber raw materials, the frayed and off-threads are also related to the structure and density of the fabric.

Inspection of zipper: In addition to checking whether the color and specifications are consistent with the process documents, the inspection of the zipper is important to check its quality. Here is a simple method to identify the quality of the zipper: the quality of the injection molding zipper, the injection molding is to inject the molten plastic material into the mold.

Visual inspection: check whether the color of the zipper is bright, whether the color of each component is consistent, whether there is obvious color difference, whether there are colorless flowers, dirt, wrinkles on the gauze; whether the surface of the element is shiny, whether the front is full, and the front is full Whether the middle part is sunken, whether there is any overflow material outside the root of the element, whether there is quality defect of missing teeth or small teeth; whether the lead at one end of the portable zipper is flat and flat, whether it is wavy or curved when the zipper is in a natural hanging state; See if the two pieces of glue on the zipper tape are symmetrically positioned, whether they are skewed or floating, and whether the glue is stiff; see if the trademarks on the bottom of the slider and the front of the flap are clear.

Feel detection: If you pull the slider by hand, do you feel the slider beating when you move forward and backward? It is normal to feel without jumping; when the slider is activated at the top stop, bottom stop and socket , Do you feel the phenomenon of being stuck or obstructed? It is normal if there is no obstruction. Is it flexible to pull the flap within 180 °? Use two forces greater than 60 ° to open the two fastener belts separately (the flap is placed flat on the pull body) Above), the pulling force should not be too large, and the pulling speed should not be too fast. At this time, if the slider does not slide, it indicates that the slider has a self-locking effect; if the slider slides, it indicates that there is no lock or the self-locking force is not strong enough; when the intubation is inserted or pulled out, the handle should be flexible; Pull the pull flap perpendicular to the plane of the pull body and pull away from the pull. The cap cannot be loosened or detached.
