Whether it is necessary to remove the stitches between the top and bottom layers for color fastness testing of interlayers7RITextile Testing Instruments, Testing Equipment Manufacturer

For interwoven interlayer fabric structures as an overall test it is not necessary to remove stitches to remove test; if it is a quilted interlining fabric and the quilting is dense, removing the stitches will damage the fabric, and it can also be used as a whole test. In the case of multi-fibre inserts, check the top and bottom layers, in the case of single-fibre inserts, the insert and test method are selected according to the material composite. 7RITextile Testing Instruments, Testing Equipment Manufacturer

In the case of samples with a large quilting spacing, where the top, bottom and intermediate layers are obviously separable when sampled, the color fastness of the top and bottom layers should be tested separately. 7RITextile Testing Instruments, Testing Equipment Manufacturer
