ES hot air cotton production process

ES hot air cotton production process:

Mixed cotton: mix various fibers and mixed fibers;


Initial opening: the mixed raw materials are transported to the pre-opening machine for preliminary opening;


Fine opening: The fiber raw material planned by the pre-opening machine is finely opened here, so that all the crimped fibers are stretched out for carding;


Cotton collection: The air pipe transports the finely opened raw materials to the cotton collector, where the opened raw materials are fluffy and soft;

Carding: The cotton collector sends the finely opened doll cotton to the carding machine, and the carding machine combs the fibers into a net;


Netting: After carding, the cotton is spread into the specified width and thickness according to the parameters;


Heat pressing: the cotton spread into a net is pressed to a specified thickness according to the specified parameters, and the fiber is initially shaped, enters the oven, and the hot pressing is completed;


Forming: The fiber after hot pressing is pressed into the specified thickness after high temperature sterilization according to the specified parameters. (The two steps of hot pressing and shaping are slightly different from the acupuncture process, pay attention to the distinction)


Cutting edge: Cut the environmentally friendly resin cotton into the specified width or sheet size according to the specified parameters, pack the goods, and complete the production.

Features of ES hot air cotton:

When the carded fiber web is thermally bonded by hot rolling or hot-air penetration, the low-melting point components form melt adhesion at the intersection of the fibers. After cooling, the fibers at non-intersections remain in their original state. This is a form of "point bonding" rather than "zone bonding", so the product has the following characteristics:


1. Pure white, fluffy, soft hand feel, good elasticity, strong warmth retention, good moisture absorption and breathability.


2. Natural flame-retardant fiber is used, and there is no dripping phenomenon. Has a permanent self-extinguishing effect.


3. A dense carbonized layer is formed during combustion. And low carbon dioxide content, only a small amount of non-toxic smoke


4. Stable acid and alkali resistance, non-toxic, and does not produce any chemical effects. The product is naturally degradable and meets environmental protection requirements.


5. Disadvantages of hot-air cotton: low strength and easy to deform.

Application of ES Hot Air Cotton:

ES hot air non-woven fabric can be used in various fields according to the density. The general thickness is used for KN95 protective masks, baby diapers, adult incontinence pads, fabrics for feminine hygiene products, napkins, bath towels, disposable tablecloths, etc.; thick products are used for making Winter clothes, quilts, baby sleeping bags, mattresses, sofa cushions, etc. High-density hot melt adhesive products can be used to make filter materials, sound insulation materials, shock absorption materials, etc.
