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.

Investigation of the effects of different needle hole covering techniques on seam characteristics of waterproof breathable fabric

“…The seam strength could also be as low as 50% compared to a sewn seam (Mesegul and Karabay, 2020). In the bonding process, materials are joined using chemicals or liquid adhesive (Jakubčionienė et al ., 2012; Mesegul and Karabay, 2020; Mikalauskaitė and Daukantienė, 2019). However, replacing traditional thread stitching with bonded seams poses significant challenges due to specific requirements such as achieving adequate bond strength, resistance to washing and cleaning, preventing staining or discoloration, preserving texture integrity, maintaining breathability and ensuring rapid setting (Jakubčionienė et al ., 2012).…”

Thermo-Physiological Comfort Properties of Sportswear with Different Combination of Inner and Outer Layers

“…Bonded layers provide high tensile strength, and bonds have the potential advantage of design flexibility. However, in terms of operating costs and total processing time that may be used to earn a profit, toxicity stitching is more effective than bonding [39]. Researchers found that a bi-layer knitted fabric with a one-tuck point made of bamboo had higher air permeability, thermal conductivity, water vapor permeability, wicking ability, and drying rate than other materials, while moisture absorption was reduced [40].…”
