Investigation of the Influence of Bonding and Thermal Ageing Duration on the Peeling Strength of Knitted Materials’ Bonds

Abstract

Bonding technology namely as “sew free” technology is usually applied for joining the pieces of sportswear and leisure clothing. Influence of the thermal ageing duration on the peeling strength of woven fabric and knitted materials bonded at 150°C temperature for 10 s, 20 s, 30 s, and 40 s durations with two polyurethane films of 0.175 mm and 0.127 mm thicknesses has been investigated in this research. Based on the research results it was shown that the peeling strength of the textile bonds is dependent on material type and bonding duration, but it is not highly affected by the ageing at 45°C temperature for 150 min, 300 min, and 450 min. During concluding it may be stated that ageing at 45°C temperatures is not main factor influencing the bond quality during its exploitation in high temperature environment.
