The present invention is directed to a resorbable hemostatic nonwoven felt suitable for use in laparoscopic procedures and to methods for manufacturing said felt.

A dispersible moist wipe generally comprises a nonwoven tissue web having regenerated fibers in an amount of about 10 to about 30 percent by weight and natural fibers in an amount of about 70 to about 90 percent by weight. The regenerated fibers and the natural fibers are hydroentangled such that the web has a geometric mean tensile strength of at least 250 grams per inch and a slosh-box break-up time of less than 155 minutes.

A wet laid and hydraulically entangled nonwoven material made from cellulosic fibers and synthetic staple fibers is disclosed. The cellulosic fibers are mixed with the synthetic fibers and formed into a web using a wet lay process. The web is then subjected to multiple hydroentangling processes. In one embodiment, the web is subjected to a first hydroentangling process while being conveyed in a horizontal position. The web is then fed over subsequent hydroentangling drums. Each side of the web is subjected to at least one more hydroentangling process.

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.

Nonwoven webs comprising a water insoluble -(1,3.fwdarw.glucan) polymer and methods of forming the nonwoven webs are disclosed. The water insoluble -(1,3.fwdarw.glucan) polymer comprises 90% or greater -1,3-glycosidic linkages, less than 1% by weight of -1,3,6-glycosidic branch points, a number average degree of polymerization in the range of from 55 to 10,000, and a ratio of apparent DPw to true DPw in the range of from 2 to 10. The nonwoven webs can be used for personal hygiene wipes, filtration media, apparel, or other uses.

The present invention is generally related to a high capacity, high efficiency nonwoven filtration media comprising a gradient pore structure. In particular, the filtration media can comprise thermoplastic synthetic microfibers, fibrillated fibers, staple fibers, and a binder. Furthermore, the filtration media may be produced without the use of glass fibers or microglass fibers. Consequently, the filtration media of the present invention does not cause the same issues as conventional filtration media that comprises glass fibers and/or microglass fibers. Moreover, the filtration media can be used to treat fuel, lubrication fluids, hydraulic fluids, and various other industrial gases.
