Some diapers to pursue to become very thin, it is inevitable to sacrifice the addition of fluffy fleece, and even some diapers will add some glue, which will obviously affect the breathability and absorption of the diapers, in order to make up for this, more absorbent beads will be added, which will inevitably lead to a stiff diaper feel, not skin-friendly, poor infusion. Therefore, the thinner the diaper is not the better, compared with the thickness, breathability and absorption capacity is more worthy of attention. Whether a diaper is breathable or not depends on its material and breathable structure. Those with good materials and reasonable air permeability settings are more breathable.

What is the difference between hot-air nonwoven and hot-rolled nonwoven?

Quintana

Hot-air nonwoven and hot-rolled nonwoven are mainly processed differently. Hot-air nonwoven is a nonwoven produced by using hot air from the drying equipment to penetrate the fiber web after the fiber is carded, so that it can be bonded by heat. Hot-rolled nonwoven fabric is a nonwoven fabric produced by heating the web with a pair of hot rollers and bonding it with a certain pressure. Hot-air bonded products are characterized by high fluffiness, good elasticity, soft handfeel, strong warmth and good breathability and permeability, but their strength is low and they are easily deformed. Hot-rolled bonded products are characterized by high yield, low cost, high hygiene, high strength and flat density, etc., but the flexibility and breathability are poor.
