Spray-bonded filling

Spray-bonded filling Spray-bonded Cotton Fiber Cotton, also known as shotcrete, a non-woven fabric. Spray-bonded structure formation theory is to spray adhesive on both sides of loose fiber layers, as in the spray when a certain pressure, and lower vacuum suction when liquid, so the internal fiber layer adhesive can penetrate , sprayed adhesive fiber layer after another after drying, curing, so that the intersection between the fibers are bonded, but not bonded to each other fibers, there is still considerable freedom. Meanwhile, three-dimensional network structure, still retains many of the air-gap volume. Therefore, the fiber layer is porous, the thermal effect of high fluffy. As the case of bonded cotton is sprayed, rather than join the binder impregnation conditions, and no longer subject to pressure in the shower after the extrusion and curing process. Therefore, the bonding state in the fiber, cross-point contact of the majority, but by less adhesive bridging agglomeration, which makes bonded cotton to maintain a loose, soft, warm the main reason.
