Methods of treating fibers comprising a polymer including at least one of a vinyl acetate moiety or a vinyl alcohol moiety, and resulting fibers or the products comprising the resulting fibers are disclosed. In an example embodiment, a method of treating fibers includes contacting a surface of a fiber comprising the polymer with a modification agent to chemically modify at least a portion of the polymer with the modification agent in a region of the fiber comprising at least the surface of the fiber to form a modified fiber.

One or more aspects of the present disclosure are directed to aqueous solutions that can be used to make substrates such as an article that can inhibit or limit one or more sources of odor. In an aspect, the aqueous solution can include one or more components, where one of the components is an inhibiting agent that can function to inhibit or limit the sources of odor in an article such as a textile.

The invention provides polymer-grafted and functionalized nonwoven membranes adapted for use in bioseparation processes, the membranes including a nonwoven web of polyester fibers having an average fiber diameter of less than about 1.5 microns, each of the plurality of polyester fibers having grafted thereon a plurality of polymer segments constructed of a methacrylate polymer, each polymer segment carrying a functional group adapted for binding to a target molecule. The invention also provides a method of bioseparation comprising passing a solution comprising the target molecule, such as a protein, through the nonwoven membrane of the invention such that at least a portion of the target molecule in the solution binds to the nonwoven membrane. A method for preparing a polymer-grafted and functionalized nonwoven membrane adapted for use in bioseparation processes is also provided.

Composite materials comprising a matrix in which are embedded reinforcing fibres and/or fabrics of modified cellulose and methods for making said composite materials.

The present invention relates to the field of denim fabric processing, specifically to an environmentally-friendly processing method for dyeing denim fabric with zero discharge. The method includes: step 1, a treatment of white warp yarns; step 2, a primary drying operation; step 3, a coating spray-dyeing operation; step 4, a secondary drying operation; step 5, a sizing operation; step 6, a ternary drying operation; and step 7, a doffing operation. In the present application, as warp yarns are dyed using the coating spray-dyeing technology, highly corrosive auxiliaries such as sodium hydrosulfite and sodium sulfide are not needed in the dyeing process, and the dyed warp yarns are not required to be treated in a washing tank, so that zero effluent discharge is achieved.

The present invention relates to a liquid (meth)acrylic syrup for impregnating a fibrous substrate; a viscous liquid syrup mainly containing methacrylic or acrylic components, and preferably hollow beads; to a process for manufacturing such a syrup; to a process for impregnating a fibrous substrate or long fibers with said viscous liquid syrup; to a fibrous substrate preimpregnated with said syrup, which is useful for manufacturing mechanical or structured parts or products; to a manufacturing process for manufacturing mechanical or structured parts or articles; and to three-dimensional mechanical or structured parts obtained by this process. The invention makes it possible to significantly reduce the exothermic peak during the polymerization of the syrup, to reduce the residual content of monomer at the end of polymerization, and to obtain parts made of composite material that have few or no defects.
