In order to ensure the quality of products, the manufacturer of spandex covered yarn is particularly important for fabric production documentary. Let me explain to you the basic fabric production documentary matters.
1. Preliminary preparation
1. The original quality sample, hand-feel sample, and color sample (pattern sample) must correspond to the customer's requirements;
2. Use the correct light source for color matching. Such as D65, TL84, C130, etc., should be relatively unified with customers;
3. The printed color samples (design samples) should be kept properly, and the bleached samples should be sealed in plastic bags;
4. Use the correct grey fabric. Without special circumstances, the blank for proofing must be the same as the blank used for bulk goods;
5. The production of head cylinder samples should be consistent with the requirements of mass production. Such as door width, color fastness, shrinkage rate, environmentally friendly materials, weight, hand feel and other requirements are consistent with the requirements of bulk goods;

2. Mass production of high-strength polyester sewing thread
1. Respond to changes in production and report to the supervisor in time, and come up with adjustment solutions in time
2. Quality tracking of each process.
(1) The finish of singeing;
(2) Hand feeling and gross effect of pre-treatment;
(3) Mercerized cloth
(4) The finalized width
(5) Color matching under the correct light source. Whether the edge difference, the color difference of the first layer, the difference of the color, the cylinder difference, and the yin and yang color meet the requirements; (6) After finishing, pay attention to whether the warp and weft density, hand feeling, weight, finished width, color fastness, shrinkage rate, etc. meet the requirements;
