Fiber/Raw Material Preparation

WEIHONGLAI's choice of raw materials is based on processability and the ultimate performance requirements of the fibre web. Fiber is the basis for all nonwoven materials. Most natural and chemical fibers can be used in nonwoven materials. In addition, we also use high-quality adhesives and finishing chemicals, which can bond the fibers in the web to each other to obtain a web with a certain strength and integrity.

Laying

The process of forming fibres into a loose fibrous web is called laying. The reduced web strength at this time is very low, and the fibers in the web may be staple fibers or continuous filaments, depending mainly on the process of forming the web. Mosen's laying process mainly consists of dry laying, wet laying, and spin laying.

Bonding

After the fiber web is formed, the reinforcement of the loose fibers held by the fiber web by the related process is called bonding, which gives the fiber web certain physical and mechanical properties and appearance. WEIHONGLAI's bonding process includes mechanical, thermal, chemical, stitch bonding, etc.

Finishing

Finishing is carried out after the bonding. Finishing is designed to improve the structure and feel of the product, and sometimes to change the properties of the product, such as breathability, absorbency and protection. Finishing methods at WEIHONGLAI can be divided into two categories: mechanical methods and chemical methods. Mechanical post-treatment includes creping, calendering, shrinking, perforating, and the like. Chemical finishing includes dyeing, printing and functional finishing.
