A fabric is disclosed and includes warp yarns of only lyocell fiber, and weft yarns of multifilament polyester only, where the fabric has a warp yarn count from Ne40 to Ne120, a weft yarn count from 15 D (denier) to 100 D, a thread count (TC) between 200 and 2000, with ends per inch in warp between 100 and 250, and picks per inch in weft being between 100 to 1800. In one embodiment, the lyocell fiber is lyocell fiber resulting from being spun in an environment where the relative humidity is maintained at between 40% and 50%, or between 44% and 46%. The resulting fabric has low shrinkage, good durability, a desirable softness, a cool feel due to its moisture-wicking properties, and an excellent uniformity in color when dyed.

A fluid management layer having an integrated, carded, nonwoven is described. The fluid management layer has a basis weight of between about 115 grams per square meter (gsm) and about 200 gsm; a plurality of absorbent fibers; a plurality of stiffening fibers; and a plurality of resilient fibers. The absorbent fibers make up from about 20 percent to about 60 percent by weight of the fluid management layer. The stiffening fibers have a dtex of between 4 and 10, and the resilient fibers have a dtex of between 3 and 12.

This application describes a method of preparation of a natural graphene cellulose blended meltblown nonwoven fabric, which comprises using a graphite powder as a raw material for preparing a graphene solution, adding the graphene solution to a slurry formed by mixing and dissolving a wood pulp with N-methylmorpholine N-oxide (NMMO), removing the water content thereof to form a spinning dope, and then directly preparing the natural graphene cellulose blended meltblown nonwoven fabric by a meltblown process. The present method does not require a highly toxic hydrazine hydrate solution. Further, by increasing the adding ratio of the graphene solution in the manufacturing process, control of the antistatic properties and thermal transferring function can be achieved, and thereby various requirements of different consumers can be satisfied. Besides, the fabric can decompose naturally after being used, and thus the product is harmless, natural, and environmentally friendly.

The present invention relates to a dispersible nonwoven fabric comprising pulp and solvent spun cellulosic fibers, characterized in that the solvent spun cellulosic fibers are fibrillated. Furthermore the invention concerns the use of the fabric in dry wipes and wet wipes.
