Abstract
A flash fabric having a high tensile resilience, including the polyethylene raw material. The gram weight G of the flash fabric is greater than 35 g/m2; the tensile resilience (RT) of the flash fabric is 40%-70%; and the aging toughness Z5 of the flash fabric is 5-15 (N·m)/g, where Z5=[RM5×EM5+RT5×ET5]/G. By means of improvements of the spinning raw materials and the process, the comprehensive performance of the product is improved.

A flash fabric having a high tensile resilience, comprising the polyethylene raw material,
- the gram weight G of the flash fabric is greater than 35 g/m2;
- the tensile resilience (RT) of the flash fabric is 40%-70%;
- and
- the aging toughness Z5 of the flash fabric is 5-15 (N·m)/g;
- wherein Z5=[RM5×EM5+RT5×ET5]/G;
- the technological process of aging treatment is as follows:
- (1) placing a sample under the conditions of 25±1° C. and the relative humidity of 65±2% for 24 hours, then measuring the tensile strength in the machine direction (MD) (denoted as RM), the tensile strength in the transverse direction (TD) (denoted as RT), the tensile elongation in the MD direction (denoted as EM), and the tensile elongation in the TD direction (denoted as ET) of the sample respectively;
- then calculating the initial toughness Z0 according to the formula;
- (2) then exposing the sample to a dry heat atmosphere at 90±1° C. for 6 hours, followed by cooling under the conditions of 25±1° C. and the relative humidity of 65±2% for 24 hours;
- and
- (3) finally, repeating the operation in step (2), and after four additional treatments, measuring the tensile strength in the MD direction (denoted as RM5), the tensile strength in the TD direction (denoted as RT5), the tensile elongation in the MD direction (denoted as EM5), and the tensile elongation in the TD direction (denoted as ET5) of the sample respectively;
- and calculating Z5 according to the formula;
- the tensile resilience (RT) is tested by the FB1 method of a KES fabric style tester.
