Fabric Inspection
Fabric inspection is a very important part of the textile production process. It can ensure that the quality and performance of the fabric meet standard requirements. The basic contents and methods of fabric inspection include the following aspects.
Appearance inspection. Appearance inspection is an important part of fabric inspection. It mainly checks whether the color, pattern, texture, gloss, feel and other aspects of the fabric meet the requirements. Appearance inspection can be completed by visual observation and hand touch, and tools such as microscopes can also be used for more detailed inspection.
Physical performance inspection. Physical performance testing refers to testing the strength, elongation, tear strength, wear resistance, etc. of the fabric. These physical performance indicators are important indicators of fabric quality, and their quality directly affects the service life and performance of the fabric.
Chemical performance testing. Chemical performance testing refers to testing the fabric's dye fastness, water resistance, light resistance, sweat resistance, etc.
Dimensional stability inspection. Dimensional stability testing refers to testing the shrinkage and deformation rate of fabrics.
Quality Control in Garment Manufacturing During Production Phase
1. Appearance quality: from left to right, top to bottom, front to back, outside to inside.
2. Yarn direction inspection: The yarn direction is consistent with that of the object being tested, and visually inspect whether the silk strands of the garment are within the allowable range.
3. Color difference inspection: At an angle of 45 degrees to the object being tested, visually inspect the sleeve seams and hem seams of the garment to see if there is any color difference.
4. Sewing inspection: Check whether the seam allowance is flat, whether there are thread throws, skipped stitches, short threads, or missing stitches, whether the open stitching is straight, and whether the width is consistent.
5. Specification measurement: Measure whether each part of the garment is within the allowable tolerance range (refer to the measurement error of bulk goods on the last page) (the process sheet shall prevail).
6. Trimming inspection: Check whether the wool and threads of the garment are trimmed, and whether the buttonholes are clean, especially if the top fabric or lining is transparent. Check whether the threads or debris inside are clean. The width of the seams inside must be consistent.
1.Ironing inspection: The parts are ironed and the clothes are flat, without yellowing, laser, water stains, dirt, etc.;
2.Threads must be thoroughly cut.
3.Label position and sewing effect, whether the label is correct, whether there are any omissions, and the texture of the polybag;
4.The color of the cotton rope, the thickness and tightness of the root, and the interlining effect;
5.Follow all instructions on the list of materials.
6.Packaging inspection: Fold straight and flat, and strictly follow the packaging instructions.
Standard Quality Assurance Tests for Garments
In garment manufacturing, several textile testing methodologies are utilized to ascertain the quality of the fabric. These tests can be broadly categorized into:
Physical Tests for Garments:
Physical testing is performed on the fabric to assess its robustness and quality. These evaluations typically encompass stretch tests (to examine the resilience of elastic bands or straps), pull tests (to determine the strength of zippers or buttons), and fatigue tests (to measure the wear and tear strength of the fabric).
Fabric Quality Tests for Garments:
Fabric quality testing involves scrutinizing the quality of the fabric through a comprehensive series of tests. A fabric sample is subjected to these tests, juxtaposing the outcomes with established standards. This process typically includes the examination of stitch density over a one-inch area, analyzing fabric composition, and measuring fabric weight per square meter.
