spraying-bonded wadding
Collodion cotton also called spray wadding, is a kind of nonwovens, that is to say, the space cotton or vacuum cotton, it is made of natural cotton fiber, artificial fiber or synthetic fiber by marathon, combing, spraying, baking curing process and. Because of its fluffy, high compression resilience, resistance to dry, wet washing and lightweight and warm etc. performance, so in recent years has become important materials for manufacturing cotton and ski jackets, space suit and blankets, sleeping bags and other bedding and some industrial activities.
Collodion structure formation principle is the binder spraying on both sides of the fluffy fiber layer, because there is a certain pressure in the spray, and the lower part of the vacuum suction suction effect, so inside the fiber layer can also penetrate the adhesive, after spraying adhesive fiber layer again after drying, curing, the interface between the fibers are bonded, but not by fiber are bonded to each other, there is still considerable degrees of freedom. At the same time, there are still many gaps in the three-dimensional network structure. Therefore, the fiber layer has a porous, high fluffy thermal effect.
