Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of grey cloth testing, especially relates to a polyester knitted grey cloth tensile test equipment. BACKGROUND

[0002] The polyester knitted grey cloth is the cloth that has not been subjected to dyeing and finishing and other post-processing procedures and is processed by knitting process with polyester as raw material, and it has the characteristics of stiffness, wrinkle resistance, low moisture absorption, easy washing and fast drying, etc. The tensile test during the production of the polyester knitted grey cloth can evaluate the performance of the grey cloth under the tensile force, including the key indicators such as breaking strength and elongation at break. Through these indicators, the manufacturer can determine whether the strength of the grey cloth meets the expected standard, whether it can withstand the mechanical tension in the subsequent processing process and the stretching situation that may be encountered in actual use. At the same time, the tensile test results can provide a basis for adjusting the production process, help optimize the knitting parameters and improve the raw material formula, and ensure the stability of the quality of the polyester knitted grey cloth.
