ECO production process
The unique wet-forming production process in the microfiber suede industry.
The Lamous wet-forming production process use various processes, such as wet laying and entangling, to impart strength and create the unique texture of the material. Lamous is manufactured and composed of environmentally-friendly raw materials.
STAGE1Direct spinning method
The short ultra fine microfibers in Lamous are manufactured by a direct spinning method, in which high-quality raw materials are spun directly into thread which is then cut into short
Other method：Composite spinning method
Composite spinning is a method whereby multiple microfibers are extracted from a thick fiber (“sea-island” type fiber) using organic solvents, and is the typical method for manufacturing microfibers. Asahi Kasei uses ultra fine microfibers with direct spinning method; a method which pays greater care and consideration for the impact to the human body.
The short ultra fine microfibers are laid on both sides (top and bottom) of the scrim layer, in a similar method to paper making, to form the unique three-layered sheet.
The ultra fine microfibers and scrim are entangled by high-pressure water jet showers to create a single, unified piece of material.
Buffing on face and creating feathery naps.
The spaces between the ultra fine microfibers are impregnated with water based polyurethane to create a strong, and elastic sheet.
Other types of polyurethane
Water based polyurethane has less impact on the human body, and is a more environmentally-friendly material than organic solvent types.
STAGE6Dyeing & Finishing
Dyeing colorfully and adding water repellency, stain-proof, and anti-static property by finishing. The color of Lamous is beautiful because the amount of polyurethane is low by the Lamous wet-forming production process, and there is little influence on dyeing.
