Bico spunbond air through bonding production line

Product overview

The bico spunbond air-through bonding production line is a spunbond nonwoven line built to produce high-end carpet backing fabric from dual-component (bico) composite filaments. It works on the bico spunbond principle: a PET/PP main component and a COPET/PE/PP sub component are spun into continuous composite filaments by slot air drawing, laid into a web, then consolidated by hot air passing through the web (air-through bonding). The finished fabric offers excellent surface smoothness, minimal thickness, high tensile and tear strength and structural stability; high water permeability and breathability, significant rigidity, and easy folding and moldability make it an ideal backing for high-end tufted carpet. The line runs core-sheath filaments of 4.0dpf or a blend of 4.0dpf (PET) + 2.0dpf (COPET), basis weights of 20–300g/m², speeds up to 200m/min, a 2.4m work width and 6,500 tonnes per year of output. 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.
