Among them, the breadth, pattern length and pattern width are expressed in cm, the dry weight per square meter (or dry weight per unit length) is expressed in g/m2 (or g/m), and the tensile elastic elongation is expressed in %. 6 Requirements 6.1 Contents of requirements The requirements for knitted warp lace are divided into two aspects. inherent quality and appearance quality. Inherent quality includes fiber content, dry weight deviation rate, washing size change rate, loose edge after washing, tensile elastic elongation, color fastness to washing with soap or soap and soda, color fastness to perspiration, color fastness to water, color fastness to rubbing, color fastness to light, formaldehyde content, pH value, resoluble carcinogenic aromatic amine dyes, unpleasant odor and other indicators; appearance quality is divided into size deviation rate, same roll (or piece) color difference, same batch color difference, straying end, local defects and scattered defects and other indicators. 6.2 Gradation requirements 6.2.1 Knitted warp lace is divided into high-quality products, first-class products and qualified products. 6.2.2 The inherent quality is rated by batches, and the appearance quality is rated by rolls (or pieces). The combination of the two is graded at the lowest grade. 6.2.3 For each indicator of inherent quality, the lowest inspection result shall be used as the evaluation basis for this batch of products. 6.4.4 For local defects, grading shall be carried out according to the range specified in Table 3 and Table 4, and each grading shall be 10 cm. 6.4.5 When measuring the appearance defects, measure by the maximum length. 6.4.6 Slitting defects. 1 defect is counted for each occurrence of rotten edge, burr, uneven teeth, etc. 6.4.7 Trimming thread end. the length shall be within 0.3 cm, otherwise, 1 defect shall be counted. 6.4.8 Holes. Where there are several holes within 3 cm of the lace fabric at the same time, it shall be counted as one. The dropped stitch and bad stitch, within 10 cm, caused by the holes will not be counted; otherwise, it shall be regarded as a dropped stitch or bad stitch. 7 Testing 7.1 Inherent quality 7.1.1 Specimen preparation 7.1.1.1 Randomly take samples according to the type, specification and color of the delivery batch. The number of samples shall be sufficient for all tests (including 3 pieces of 700 mm full-breadth samples for the washing size change rate). 7.1.1.2 The sampling distance shall be at least 1.5 m from the cloth head, and the samples taken shall not have defects that affect the test results. 7.1.2 Test method 7.1.2.1 Fiber content Carry out according to GB/T 2910 (all parts), FZ/T 01026, FZ/T 01057 (all parts), FZ/T 01095 and other regulations. 7.1.2.2 Dry weight deviation rate 7.1.2.2.1 The dry weight per square meter shall be tested in accordance with the provisions of FZ/T 70010.For the test of dry weight per unit length, according to the entire breadth of the lace, take 3 pieces evenly according to one or several complete patterns along the length direction, measure the length, dry and weigh, and calculate the dry weight per unit length. For the dry weight per square meter of lace fabric with uneven structure, take samples by the method of the test of dry weight per unit length, measure the length and width of the sample, dry and weigh it, and calculate its dry weight per square meter. Perform according to GB/T 5713. 7.1.2.9 Color fastness to light Perform according to Method 3 of GB/T 8427-2008. 7.1.2.10 Formaldehyde content Perform according to GB/T 2912.1. 7.1.2.11 pH value Perform according to GB/T 7573. 7.1.2.12 Resoluble carcinogenic aromatic amine dyes Perform according to GB/T 17592. 7.1.2.13 Unpleasant odor Perform according to GB 18401. 7.2 Appearance quality 7.2.1 Detection rules 7.2.1.1 Visual inspection shall be adopted as the inspection method of appearance quality. 7.2.1.2 The appearance quality shall be randomly sampled by variety, specification and color according to the delivery batch number, and the sampling quantity shall not be less than 2%, but not less than 2 rolls (or pieces). 7.2.2 Inspection conditions Appearance quality inspection is mainly based on the front of the product, by cloth inspecting machine inspection or on a horizontal inspection table, using normal daytime northern light or fluorescent lighting; the illumination is not less than 750 lx, and the distance between the eyes and the cloth surface is about 60 cm. The speed of the cloth inspecting machine is 16 m/min ~ 18 m/min. 7.2.3 Test 7.2.3.1 Size deviation rate 7.2.3.1.1 Tools. steel ruler or steel tape, the length of which must be greater than the width of the sample, and the accuracy is 0.1 cm. ......
