    摘要: This invention is directed to an improved nonwoven product comprising a nonwoven web of fibers bonded together with a sufficient amount of binder comprised of a polymer comprised of vinyl acetate, ethylene, and a crosslinking monomer to form a self-sustaining web. The improvement in the nonwoven product resides in the use of a polymer having a crystalline melting point (Tm) ranging from 35 to 90null C., preferably 50 to 80null C.; measured at a heat rate of 20null C./minute. The polymer should have a crystalline heat of fusion (Hf), which typically range from about 2 to about 50 joules per gram and a low glass transition temperature (Tg), e.g., from 10 to null40null C., typically null15 to null35null C.

    摘要: The present invention is directed to a fibrous nonwoven material made of chemically bonded fibers, where the fibers are bound with a polymeric binder in an amount which is sufficient to bind the fibers together to form a self-sustaining web, and where the binder comprises from 55 to 96 percent by weight of a film-forming polymer; from 4 to 45 percent by weight of one or more opacifying agents; and 0 to 2 percent by weight of one or more adjuvants, based on the binder composition solids. The binder composition provides opacity to the nonwoven material. The binder composition is especially useful in light basis weight nonwovens, and provide high opacity and tensile strength both dry and wetted.

    摘要: The composite nonwoven fabric for protective clothing of the present invention comprises (A) a water vapor-permeable, water-resistant nonwoven fabric made of polyolefin-based ultra-fine fibers having an average fiber diameter of 5 nullm or less, (B) a heat-bonding nonwoven fabric made of thermoplastic elastomer ultra-fine fibers, and (C) a porous fabric. The nonwoven fabric B is interposed between the nonwoven fabric A and the porous fabric C, and the fabrics A, B and C being integrally bonded to each other. The composite nonwoven fabric is suitable for a protective clothing because it is water vapor-permeable and water-resistant on its outer side to be exposed to outside air, and is of high strength, sweat-absorbable and antistatic on its inner side, and also well-balanced in these properties.

    摘要: An absorbent composite sheet is thin and has a surface to be easily situated in dry condition. The absorbent composite sheet includes at least a first layer and a second layer. The first layer placed on the side of receiving a liquid is a non-woven fabric fabricated from thermoplastic synthetic resin fibers. The second layer stacked below the first layer is a non-woven fabric fabricated by entangling cellulose type fibers and thermoplastic synthetic resin fibers. The first layer and the second layer are joined by fuse bonding synthetic resin fibers of the first layer and synthetic resin fibers of the second layer. The liquid applied on a surface of the first layer is transferred to the second layer through gaps between synthetic resin fibers of the first layer.
