Slot drawing thermal bonding production line

Product overview

The slot drawing thermal bonding production line is a spunbond nonwoven line built to produce thermally bonded fabric using slot filament drawing. It works on the spunbond principle: PET or PLA chips are melt-spun into continuous filaments by slot air drawing, laid into a web, then consolidated by heat with no chemical binder. Continuous-filament web forming gives even coverage and consistent strength. The finished fabric offers high tensile strength, a small transverse-to-longitudinal strength ratio, good dimensional stability, aging resistance and corrosion resistance, suiting gas, liquid and composite filter media, building reinforcement, household textiles, clothing interlining, floor-leather base cloth, shed-cover materials and packaging. Compared with tubular drawing, slot drawing yields finer filaments at higher speed: basis weights of 10–150g/m² at 1.0–3.0dpf and 15–150m/min, favoring lightweight, high-speed fabrics. The line comes in three work widths of 1.6m, 2.4m and 3.2m for outputs of 2,400, 3,700 and 5,000 tonnes per year. Vina Nonwoven is the authorized Huayang representative in Vietnam, advising on line configuration by work width and target output, with installation, commissioning and warranty support.
