    摘要: The invention relates to non-woven fabrics comprising threads not produced with the spun-bonding method, for example made of non-melt spinnable thread-forming materials. The use of these fibers, optionally in combination with filaments produced using the spun-bonding method, allows the production of novel non-woven fabrics with novel property combinations. The production can be carried on conventional spun-bonding equipment, wherein part of the extruding devices are used as conveyors for the threads not produced with the spun-bonding method.

    摘要: The present invention relates to a process for the preparation of a mixture of cellulosic fibers and microfibers. Said process comprises: the preparation of a cellulosic solution (C); the extrusion of said solution (C) through the hole or holes of a die (1); the disintegration of said solution (C) when it comes out of said hole or holes by projecting a liquid or gas fluid (F) in a direction making an angle lower than or equal to 75 degrees with the axis of said die (1); said fluid (F) being neutral or appropriate to regenerate or precipitate, only partially, the cellulose; the reception in a cellulose regeneration or precipitation bath, of the dispersion generated at the disintegration step; the recovery of the mixture of fibers and microfibers, more or less bonded, obtained in said bath. Said process provides for the preparation of mixtures rich in microfibers (with a fineness lower than 1 dtex, particularly between 0.5 and 0.3 dtex). It also provides for the continuous preparation of nonwoven materials.

    摘要: Provided herein is a new fire barrier nonwoven composed of flame retardant (FR) cellulosic fiber(s) and untreated cellulosic fiber(s) and optionally a binder fiber and methods of making the same, wherein the FR cellulosic fiber contains FR chemical(s) or FR compound(s) that have melting point or decomposition temperature at 400° C. (752° F.) or below. The FR performance of the new nonwoven provided herein is comparable to the conventional FR nonwoven (FR cellulosic fiber/binder fiber), but has advantages in cost effectiveness.
