At least following to method and this method of producing the nonwoven fabrics which consist of the endless fiber which partly is superfine and are hardened, the nonwoven fabrics which are produced

摘要

The water flow endless it is confounded following to the split fiber and melt blown method, the fiber which is produced is known. Constitution of the split fiber consists of the plural polymers, quite cost is required for production. Following to melt blown method, strength of the fiber which is produced fails by the draft air which high is heated inevitably and often breaks in the staple fiber. Profitably as for the fleece or fleece part when it has consisted of the endless yarn, it is profitable. This endless yarn in the monofilament of size class approximately 2 millimicrons, separates to longitudinal direction on the basis of the haidorosutateitsuku pressure whose inside of the fiber is high at the time of production, quite is thin because of this, the endless filament whose strength is large is produced. Is produced from this the fleece which thin fiber in order to obtain the especially wipe fleece is fulled with confounding the hydro-dynamic system.
