A process for foam forming webs is disclosed. The foam formed webs can be used as wiping products, such as industrial wipers, food service wipers, and the like. The web contains a mixture of cellulosic fibers and longer, strength building fibers. The web is foam formed and then subjected to one or more hydroentangling steps. After hydroentangling, the web is dried in a non-compressive manner.

Disclosed are materials comprising a fiber material and an agent having at least one having improved tensile strength, in particular wet tensile strength, vis-à-vis fiber materials known from the art. While these fiber materials may be of use in various fields, in particular household products, hygiene products and the like, these fiber materials are of particular use in wound treatment. Also disclosed is a method for producing these materials.

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.

A nonwoven fabric manufacturing facility includes a fiber assembly manufacturing step and a heating and drawing step. In the fiber assembly manufacturing step, fibers formed using an electrospinning method are collected to form a fiber assembly. In the heating and drawing step, the fiber assembly is drawn to form nonwoven fabric in a state where the fiber assembly is heated to a melting point of the fibers. In the formed nonwoven fabric, an average pore diameter is 15 μm or more, a relative standard deviation of a pore diameter distribution is 0.1 or less, and an average fiber diameter of the fibers is 3 μm or less.
