What can melt blown non woven fabric machine in China do?
Many people still think their handmade cotton diapers are good, not only breathable but also save money. In fact, this is not the case. Babies are naturally lively and active, and their farts are easily dirty. Babies also like to touch things with their small hands, so it is inevitable that they will touch their farts, together with the habit of eating their hands, which will cause digestive tract diseases. At the same time, the reproductive organs of infants should also be protected. The use of diapers can solve this difficult problem very well, and bring great convenience to the baby and mother. There is no need to change frequently at night. The baby can sleep until dawn, and it will be much easier for people and mothers.
Diapers are mainly made from surface coating, polymer absorbent resin, PE bottom film, rubber and other materials.
The surface coating of diapers is made up of two materials: hot air non-woven fabric and waterproof nonwoven fabric.
Hot air non-woven fabric is a kind of non-woven fabric, which combs the fibre web by hot air on drying equipment and makes it penetrate, heat and bond. Hot-air adhesives have the characteristics of high fluffy, high elasticity, soft feel, strong warmth retention and good air permeability, so generally good diapers are made of hot-air non-woven fabric.
Hot-air non-woven fabric production process requirements are higher, manufacturing machinery costs are higher, so the use of hot-air non-woven paper diapers will be more expensive, of course, the baby will wear more comfortable.
Performance requirements:
(1) to achieve certain strength, it has good tensile strength.
(2) with good permeability, the liquid can enter the absorption core quickly and shorten the penetration time, the longest being no more than 3S;
(3) low permeability, keep the skin contact surface dry and ensure the user’s comfort.
(4) the appearance accords with hygienic requirements, clean, bright and white.
(5) good air permeability, good softness and good comfort.
