The present invention relates to a direct dissolving process for the production of polysaccharide fibers which contain (1.fwdarw.3)-glucan as a fiber-forming substance, with aqueous sodium hydroxide solution as a solvent, as well as to the fibers made thereby, and to their use.

It is described a nonwoven cellulose fiber fabric directly manufactured from a lyocell spinning solution. The fabric comprises a network of substantially endless fibers. The fabric is characterized by at least one of the following features: (i) a rate of liquid spread is at least 3000 mm2 within 5 minutes; (ii) a water absorbing capability is characterized by a wicking speed of at least 0.25 gram water per 1 gram fabric and 1 second. It is further described a method and a device for manufacturing such a fabric, a product or composite comprising such a fabric, and various use applications for such a fabric.

A liquid-retaining sheet contains a liquid-retaining layer that is able to absorb a liquid component, and the liquid-retaining layer is formed from a nonwoven structural member containing a transparent fiber. In the liquid-retaining sheet, the transparency shown below is adjusted to not more than 0.27.
Transparency=Whiteness (%) of a sheet impregnated with 700% by mass of water relative to the sheet mass/Basis weight (g/m.sup.2) The transparent fiber may contain a cellulose-series fiber substantially free from a carboxyl group (in particular, a regenerated cellulose fiber such as a solvent-spinning cellulose-series fiber). The proportion of the solvent-spinning cellulose-series fiber may be not less than 30% by mass in the transparent fiber. The liquid-retaining sheet may be a skin care sheet (in particular, a facial mask) that is impregnated with a liquid component containing a cosmetic preparation. The liquid-retaining sheet has an improved transparency in a wet state in spite of a nonwoven structural member contained in the sheet and shows a suitable strength in a wet state.

The present invention provides a wet-laid tissue product comprising regenerated cellulose fibers that can provide 25 percent or less of the total weight of the wet-laid tissue product. The regenerated cellulose fibers can have a linear density less than about 1.5 dtex and a fiber length of less than 6.0 mm. The wet-laid tissue product can provide improvements in softness at a given strength.
