Unique production process

The unique wet-forming production process in the artificial 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 highly-selected 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 Asahi Kasei uses ultra fine microfibers with direct spinning method without using organic solvents.

STAGE2Wet laying

Wet-forming process

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.



Wet-forming process

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.
