Description

Technical Field

[0001] This utility model belongs to the field of flocking fastness testing technology, and in particular relates to a flocking fastness testing device for flocking yarn. Background Technology

[0002] Currently, the production technology of material physical and mechanical property testing instruments in the domestic market is quite mature. The main testing indicators of these instruments are the determination of tensile breaking strength, tear strength, and peel strength of materials. Their testing mechanism involves applying an increasing load to the sample until it breaks, thus determining the force required for the sample to fail. For flocked yarn, during use, the flocked yarn will continuously wear down, eventually breaking and becoming unusable. The flocking fastness of flocked yarn is directly related to its service life, but the aforementioned instruments, in terms of both instrument structure and testing mechanism, cannot meet the testing requirements for the flocking fastness of flocked yarn.
