Grey cloth napping experiment machine Technical Field The invention relates to the technical field of textile detection, in particular to a grey cloth napping experiment machine. Background In the production, development and quality inspection of textiles, the anti-pilling performance of grey cloth is a key quality index, and is directly related to the appearance retention and durability of final finished products such as clothing and home textiles. Whether the production quality is controlled, the fabric process is optimized, or an authoritative detection report is provided, a test method and a test device capable of objectively, quantitatively and repeatedly simulating and evaluating the fuzzing phenomenon of the surface of the grey cloth due to friction are needed. The equipment for realizing the process standardization, namely the grey cloth napping experimental machine, is a basic tool for scientific quality assessment in the textile industry. Currently, there are several methods and apparatus for evaluating the pilling performance of fabrics. The manual friction comparison method based on the sensory evaluation of the inspector is high in subjectivity. More commonly, universal fabric wear-resistant pilling testers such as Martindale wear-resistant testers and round track pilling boxes are adopted. Such devices typically have standard friction heads, prescribed pressure and motion trajectories, and are capable of testing cut fabric samples and determining pilling grade by post-visual rating. During or after the test, some equipment may also use manual brushing or simple collection to handle the shed fibers. While the above-described prior art devices provide more standardized testing conditions than manual, there are systematic shortcomings in servicing the specific, high standard scenario of greige cloth performance testing. Firstly, the general equipment is not specially designed for the testing characteristics of the grey cloth, particularly the large-breadth semi-finished product without after finishing, and has limitations in clamping the sample, maintaining the flatness and simulating the special friction working condition of the grey cloth. Secondly, a large amount of loose fluff generated in the testing process can fly and pollute laboratory environment, and the long-term stability of equipment and the sanitation of the testing environment are affected, so that the requirements of on-line quality inspection of production enterprises and third-party detection institutions on equipment reliability and environmental cleanliness are not met.
