Tubular drawing thermal bonding production line

Product overview

The tubular drawing thermal bonding production line is a spunbond nonwoven line built to produce thermally bonded fabric using tubular filament drawing. It works on the spunbond principle: PET or PLA chips are melt-spun into continuous filaments by tubular air drawing, laid into a web, then consolidated by heat with no chemical binder. Forming continuous filaments directly into the web yields 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. Tubular drawing covers a wide basis-weight range of 20–240g/m² at 1.0–4.0dpf and 5–70m/min, favoring heavier and medium-weight fabrics. The line comes in three work widths of 1.6m, 2.4m and 3.2m for outputs of 1,500, 2,200 and 3,000 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.
