Technical Field
[0001] The utility model relates to the technical field of double-sided jacquard cashmere sweater detection equipment, in particular to a device for detecting the knitting density of double-sided jacquard cashmere sweaters. Background Technique
[0002] With the continuous development of technology, people's living standards are also constantly improving. At present, people's pursuit of clothing is not only the beauty of clothing, but more importantly, the comfort and health of clothing. Due to the advantages of cashmere fabrics such as comfort and warmth, and the advantages of cashmere knitted fabrics such as good elasticity and extensibility, the double-sided jacquard cashmere sweater industry has developed rapidly. High-quality double-sided jacquard cashmere sweaters have strict requirements for their fabric density, so the fabric yarn density has become an important evaluation index for fabric quality. Traditional fabric density is mainly detected manually. The tester counts the number of warp and weft threads per inch through a magnifying device to obtain the warp and weft density of the fabric, or uses a fabric warp and weft density mirror to detect the warp and weft density of the fabric. These methods require a high degree of concentration and patience from the tester, but long-term detection is likely to cause fatigue and laxity of the personnel, resulting in detection errors and detection failures caused by human factors. In addition, during the detection process of the knitting density of double-sided jacquard cashmere sweaters, the cashmere sweater needs to be laid flat so that the knitting structures on both sides do not overlap, and the front and back sides of the double-sided jacquard cashmere sweater need to be detected separately. Currently, all are completed manually, with a large manual labor intensity and large errors in the detection results. Content of the Utility Model
