Polyester DTY silk is made of polyester chip (PET) as raw material, first through high-speed spinning to make pre-oriented yarn (POY), and then through drawing and false twist texturing to form. This processing process gives DTY silk certain elasticity and shrinkage, while retaining the excellent properties of polyester fiber. After production, the performance of polyester DTY silk needs to be tested, including the tensile strength test of polyester DTY silk. Publication (announcement) number: CN220960969U discloses a polyester DTY silk strength testing device, including a support, a body arranged on one side of the support, a clamping assembly, the clamping assembly has two groups and coaxially opposite, to implement coaxial clamping of both ends of the polyester DTY silk to be tested, one group of clamping assembly is drivingly connected with the body, to move and pull the polyester DTY silk when measuring the polyester DTY silk, the other group is fixedly installed on the support, a yarn feeding needle can be pulled out and inserted into the support, when clamping the polyester DTY silk, the yarn feeding needle clamps the polyester DTY silk and inserts it into the clamping assembly.
