[Source: GB/T 26380-2022, 4.1.15] 4 Requirements 4.1 Requirements Requirements include basic safety performance. Intrinsic quality and appearance quality. 4.2 Assessment items Intrinsic quality assessment items include density deviation rate, quality deviation rate, fibre content tolerance, fabric thickness deviation, breaking strength, tearing strength, fault degree, washing size change rate, dry cleaning size change rate, colour had 10 items. Appearance quality assessment items include colour difference (and confirm the sample comparison), width deviation rate, appearance defects 3 items. 4.3 Grading regulations 4.3.1 The grading is based on the unit of horses. In addition to the density deviation rate in the intrinsic quality of the other assessment items according to the criticism of the grade; density deviation rate and appearance quality according to the horse grade. 4.3.2 The grade is assessed by the lowest grade item in the intrinsic quality and appearance quality, and is divided into superior grade, first grade and second grade. Those below the second grade shall be the outer grade. 4.4 Basic safety performance Should comply with the provisions of GB18401. 4.5 Intrinsic quality requirements Intrinsic quality requirements according to Table 1. 4.6 Appearance quality requirements 4.6.1 Appearance quality requirements in accordance with Table 2. 5 Test methods 5.1 Intrinsic quality test methods 5.1.1 Density deviation rate According to GB/T 4668-1995 implementation, arbitration test using method A. Each sample should be measured at least 3 m from the ends of five weft density, each two measurements at an interval of more than 2 m, the arithmetic mean of the measured values, according to GB/T 8170 revised to 0.1 root/10 cm. 5.1.2 Quality deviation rate According to GB/T4669 - 2008 in the implementation of method 5, arbitration test according to the implementation of method 3. 5.1.3 Tolerance of fibre content According to GB/T 2910 (all parts), FZ/T 01026, FZ/T 01057 (all parts) implementation. 5.1.4 Fabric thickness Executed according to GB/T 3820. colour 5.1.5 Breaking strength Executed according to GB/T 3923.1. 5.1.6 Tearing strength According to GB/T 3917.1 implementation. 5.1.7 Degree of faulty According to GB/T13772.2 implementation, the width of the sample size using 75 mm. 5.1.8 Washing size change rate According to GB/T8628,GB/T 8629-2017,GB/T 8630. The washing method adopts the 4H procedure in GB/T 8629-2017, and the drying method adopts method A (hanging drying). 5.1.9 Dry cleaning size change rate According to GB/T 8628, GB/T 19981.2, the dry cleaning load in the dry cleaning program is reduced to 66% of the normal material, no water additives are used, the washing time is reduced to 5 min, the rinsing time is reduced to 3 min, and the rest of the material is dry cleaned with the same parameters as the normal material. Use an iron for ironing. 5.1.10 Colour fastness 5.1.10.1 The test method for colour fastness to soaping shall be in accordance with method A(1) of GB/T 3921-2008. 5.1.10.2 Dry-cleaning fastness test method according to GB/T 5711. 5.1.10.3 Water fastness test method according to GB/T 5713. 5.2 Appearance quality test method 5.2.1 Deviation rate of width Executed according to GB/T 4666. 5.2.2 Colour difference The use of D65 standard light source or north natural light, illumination of not less than 600 lx, the sample should be measured in the same part of the latitude and longitude, human light and the sample surface at an angle of about 45 °, the inspector's line of sight is approximately perpendicular to the sample surface, the distance of about 60 cm visual inspection, and GB / T 250 standard sample card comparison rating. 5.2.3 Appearance faults 5.2.3.1 The use of warp inspection machine or latitudinal bench inspection. Arbitration inspection using the warp inspection machine inspection. 5.2.3.2 light source using daylight fluorescent lamps, the average illumination of the table surface 60O lx ~ 700 lx, the ambient light source control in 150 lkx or less. Latitudinal inspection can be used to natural north light, the average illumination in 320 lx ~ 600 lx. 5.2.3.3 warp inspection machine, the inspection speed of (15 ± 5) m / min. weft table inspection speed of 15 pages / min. 5.2.3.4 The inspector's eyes are about 60 cm~80 cm from the centre of the fabric surface. 114 cm width and below are inspected by one person, 114 cm width and above are inspected by two people. 5.2.3.5 The appearance of defects to the surface of the fabric flat spread front prevails, the reverse side of the fault shadow go surface should also be scored. The size of the defects according to the maximum amount of warp or weft. 5.2.3.6 weft slope, flower slope, check slope test method according to GB/T 14801, execution you. 5.3 Basic safety performance test method According to GB 18401 implementation. 6 test rules Inspection rules according to GB/T15552 implementation. 7 Packaging and marking 7.1 Packaging 7.1.1 Packaging should ensure that the quality of the product is not damaged, deterioration, easy to transport. 7.1.2 Pile upright velvet fabric, using hook frame boxed, should not be folded long pressure, packaging should be flat. 7.1.3 Velvet fabric with inverted pile, rolled in paper tubes, with a trademark and a symmetrical waist seal on the outer layer and a plastic film bag on the outside. 7.2 Marking 7.2.1 The logo of velour fabrics shall be clear. Clear, durable, easy to identify. 7.2.2 each velvet fabric on the back of the two ends, stamped with the inspector code. If the piecing, should be in the cut ends with the tip of the seal, hanging a small tag, indicating the length. If there is a false open cut, must be in the side of the defective end, stamped with a fault mark, and hanging red line to indicate. 7.2.3 Each velvet fabric hanging a hangtag, the content of GB/T 5296.4, including the name of the enterprise, address, name, width, fiber content, washing methods, implementation of standards, grade, length (if there is a false open cut, but also write the net length after the release of the foot), etc.. 7.2.4 Boxed velvet boxes must indicate: the name of the company, address, name, product number, width, colour number, fibre content, grade, length, etc. 7.2.5 Velvet fabric in fixed number of pieces (boxes), each box should be accompanied by a packing list, outside the box should be the following signs: name of the enterprise, address, contract number, box number, name, product number, colour number, number of piles, length, gross weight, net weight, volume, date of delivery, moisture-proof signs, etc. Appendix A (informative) appearance defects categorization table
