Fiber/Raw Material Preparation

Juhua'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. Juhua'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. Juhua'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 Juhua 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.

Prilling

The granulation process is to grind the purchased calcium carbonate and polystyrene, and after drying and adding an adhesive, the particles having good fluidity and a particle diameter of about 0.1 mm are prepared. This process can make the final product more filling, firm and more detailed.

Film Formation

There are three steps in this process: the first step is to liquefy the raw material through a temperature of 250 degrees and shape it through cooling rolls; the second step is to preheat and then stretch and control the amount of gas permeability; the third step is to roughen the surface of the film by corona treatment, which is advantageous for ink adhesion.

Printing

Juhua's products are all produced with food-grade environmentally-friendly water-based inks and advanced and efficient flexo presses. The products produced will not have any odor at all, completely eliminating the market complaints of consumers' most sensitive diaper odor residues. The color registration is accurate. We can produce up to 6 color positioning and cutting gas permeable membranes.

Slitting

Juhua uses a high-speed stable, precise edge-cutting slitter. During the slitting, the staff confirms the quality status of each product according to the process card, rejects the abnormality, and inputs the processing result into the slitting process card to ensure that the products transferred into the package are qualified.
