Intrinsic quality includes indicators such as fiber content, formaldehyde content, pH value, odor, decomposable carcinogenic aromatic amine dye, colour fastness to washing with soap or soap and soda, colour fastness to rubbing, colour fastness to perspiration, colour fastness to water, size stability to washing, and pilling. Appearance quality includes indicators such as surface defects, size deviations of major parts of the finished product, size differences of symmetrical parts, stitch elongation, and sewing regulations. 5.2 Grading regulations 5.2.1 The quality grade of knitted shape inner wear-elastic style products is divided into superior product, first-class product, and qualified product. 5.2.2 For the quality grading of knitted shape inner wear-elastic style products, the intrinsic quality is graded by lot (delivery lot); the appearance quality is graded by piece. The combination of intrinsic quality and appearance quality is graded at the lowest grade. 5.2.3 The indicators of intrinsic quality take the lowest one of the test results as the grading basis of this lot of products. 5.2.4 When the appearance quality problems of different grades are found on the same product, it is graded at the lowest grade. Only two extreme surface defects of the same grade are allowed on the same product; those exceeding this limit shall be reduced by one grade. 5.3 Intrinsic quality requirements 5.3.1 The intrinsic quality requirements are shown in Table 1. Table 5 -- Stitch density regulations In number of stitches per 2 centimeter Category Flat seam Flat double needle Three- needle machine Four- needle machine Rolling collar Rolling belt Wide banding machine Overlock Overlock and rolling rim ≥ 9 8 9 8 9 9 8 8 7 Note: The stitch density is measured in the middle of a sewing process. 5.4.5.6 The seam width of the overlock machine, for three threads, is not less than 0.3 cm; for four threads, is not less than 0.4 cm; for five threads, is not less than 0.6 cm. 5.4.5.7 For the skipped stitch for single stitch of double-needle covering stitch machine, it is allowed to disperse 1 stitch in 3 places.6 Tests6.1 Sampling quantity 6.1.1 As for appearance quality, the delivery lot is randomly sampled 1%~3% according to the variety, colour, and size, no less than 20 pieces. If the lot size is less than 20 pieces, the total is inspected. 6.1.2 As for intrinsic quality, the delivery lot is randomly sampled 4 pieces according to the variety, colour, and size. If insufficient, the number of pieces may be increased. 6.2 Inspection of appearance quality 6.2.1 Inspection conditions for appearance quality 6.2.1.1 Generally, use lamplight to inspect. USE a 40 W white-light fluorescent lamp; ADD a lamp cover thereon. The vertical distance between the lamp cover and the center of inspection table is (80±5)cm. 6.2.1.2 If natural light is used indoors, the light source shall enter in the north to the left (or right) upper angle, so that the sunlight cannot be directed to the product. 6.2.1.3 During the inspection, the product shall be spread evenly on the inspection table. The table shall be covered with a white cloth. The line of sight of the inspector shall face the surface of the flat stand product. The visual distance is more than 35 cm. Flatten the product; MEASURE 10 cm in the middle of the sleeve seam, side seam, or trousers seam and mark it; STRETCH hard and measure the extended size of the seam. According to formula (1), calculate the stitch elongation. The final result, according to GB/T 8170, is rounded-off to a single digit. Where: B - Stitch elongation; L - Stitch size after stretching, in centimeters (cm). 6.3 Inspection of intrinsic quality 6.3.1 Inspection conditions for intrinsic quality 6.3.1.1 The sample taken shall not have any defects affecting the test. 6.3.1.2 When the test of size stability to washing is carried out, the sample shall, at room temperature, be evenly spread on a smooth surface for 20 h. Under the conditions of a test chamber temperature of (20±2)°C and a relative humidity of (65±4)%, after humidifying for 4 h, carry out the test. 6.3.2 Test methods for intrinsic quality 6.3.2.1 Fiber content Execute according to FZ/T 01057 (all parts), GB/T 2910 (all parts), FZ/T 01026, FZ/T 01095. The sampling locations include at least the middle of front waist of the top and the middle of abdomen of the trousers. 6.3.2.2 Formaldehyde content Execute according to GB/T 2912.1. 6.3.2.3 pH value Execute according to GB/T 7573. 6.3.2.4 Odor Execute according to GB 18401. 6.3.2.5 Decomposable carcinogenic aromatic amine dye 6.3.2.11 Pilling Execute according to Method E in GB/T 4802.1-2008. The grade is evaluated based on the fabric style and the pilling shape according to GSB 16-1523.7 Judgment rules7.1 Appearance quality According to the variety, colour, and size, calculate the rate of non-conformity. As for the inner packaging mark error, the rate of non-conformity is calculated according to the piece. The outer packaging error is not allowed. If the rate of non-conformity is less than or equal to 5.0%, this lot of products is judged to be qualified. If the rate of non-conformity is more than 5.0%, this lot of products is judged to be unqualified. 7.2 Intrinsic quality 7.2.1 As for the intrinsic quality, according to the requirements of 5.3, if one item is not met, this lot of products is judged to be unqualified. Among them, if the colour fastness item is not met, according to the colour, this lot of products is judged to be unqualified. 7.2.2 As for the size stability to washing, the arithmetic mean of all the samples is used as the inspection result. If qualified, this lot of products is judged to be qualified. If unqualified, this lot of products is judged to be unqualified. If there are both shrinkage and swell test results, the arithmetic mean of the two samples which shrink (or swell) is used as the inspection result. If qualified, this lot of products is judged to be qualified. If unqualified, this lot of products is judged to be unqualified. 7.3 Re-inspection 7.3.1 If either party objects to the inspection results, it may request a re- inspection. 7.3.2 The re-inspection results shall be carried out in accordance with the provisions of 7.1 and 7.2. The judgment shall be subject to the re-inspection results. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
