The invention provides a method for preparing tissue-adhesive sheets that may suitably be applied as an implantable haemostatic or sealing construct during surgical procedures, said method comprising: providing a fibrous sheet comprising a three-dimensional interconnected interstitial space; providing reactive polymer particles comprising a water-soluble electrophilic polymer carrying at least 3 reactive electrophilic groups that are capable of reacting with amine groups in blood under the formation of a covalent bond; placing the fibrous sheet and the reactive polymer particles between two electrodes; simultaneously subjecting the fibrous sheet and the reactive polymer particles to an electric field of 0.1 to 40 kV/mm to impregnate the interconnected interstitial space of the fibrous sheet with the reactive polymer particles.

A fabric coating composition can include water, from 3 wt % to 95 wt % oxazoline reactive compound by dry weight including an oxazoline group, and from 3 wt % to 70 wt % cationic charging agent by dry weight. The fabric coating composition can have a pH from pH 2 to pH 6.

To provide a fiber bundling agent containing: a vinyl ester resin (A) having an alkoxy polyoxyalkylene structure, a urethane bond, a (meth)acryloyl group, and an epoxy group; and an aqueous medium, in which the vinyl ester resin (A) has an epoxy equivalent of 3,500 g/eq to 11,000 g/eq. Since the fiber bundling agent is excellent in bundling properties and in interfacial shear strength between fiber resins, the fiber bundling agent is suitably used for production of a fiber material capable of imparting excellent strength to a molded product.

The present invention relates to a modified cellulosic fiber that comprises anionic moieties in an amount of more than 0.25 mol/kg of dry fiber and has applied thereon a polymeric modifying agent in an amount of from 0.5 wt. % to 5.0 wt. %, based on dry fiber, the polymeric modifying agent comprising cationic moieties with a charge of at least 1.5 meq per gram of polymer and the molar ratio of anionic moieties to cationic moieties contained in the fiber is in the range of from 1:1 to 25:1. The fiber according to the present invention is characterized in that the anionic moieties are incorporated in the fiber and are from carboxymethylcellulose, and that the polymeric modifying agent comprising cationic moieties is selected from the group consisting of polydiallyldimethylammonium chloride (poly-DADMAC), poly(acrylamide-co-diallyldimethylammonium chloride) (PAM-DADMAC) and mixtures thereof. The invention furthermore relates to a nonwoven product or fabric comprising the modified cellulosic fiber.

A laminated body formed by laminating a fiber substrate composed of a plurality of fibers and a polymer layer formed from a polymer latex. The polymer layer covers the fiber substrate in a state in which a portion of the polymer layer has permeated among the fibers. A ratio (t.sub.1/d) of a thickness t.sub.1 of the portion of the polymer layer that has permeated among the fibers (from a top surface of the fiber substrate) to a substrate layer average thickness d is 0.1 to 0.95. A thickness t.sub.2 of the portion of the polymer layer covering the top surface of the fiber substrate (from the top surface of the fiber substrate) is 80 μm or more.
