    摘要： It is an object of the present invention to provide a stable production process for a melt-blown nonwoven fabric comprising thin fibers and having extremely few thick fibers [number of fusion-bonded fibers] formed by fusion bonding of thermoplastic resin fibers to one another, and an apparatus for the same. The present invention relates to a melt-blown nonwoven fabric comprising polyolefin fibers and having (i) a mean fiber diameter of not more than 2.0 µm, (ii) a fiber diameter distribution CV value of not more than 60%, and (iii) 15 or less fusion-bonded fibers based on 100 fibers; a production process for a melt-blown nonwoven fabric characterized by feeding cooling air of not higher than 30 °C from both side surfaces of outlets of slits 31 from which high-temperature high-velocity air is gushed out and thereby cooling the spun molten resin; and a production apparatus for the same.

    摘要： Methods related to forming superabsorbent composite core structures using superabsorbent materials, such as superabsorbent polymers (SAP). In one method superabsorbent material is sprayed simultaneously with an adhesive to form a superabsorbent layer adhered to a first flexible sheet of material. A second flexible sheet of material is applied to the superabsorbent layer to position the superabsorbent layer between the first and second flexible sheets of material. At least one of the first or second flexible sheets of material is liquid permeable to allow liquid to penetrate into the superabsorbent layer from outside the composite product.

    摘要： A nonwoven fabric is provided having a plurality of semi-crystalline filaments that are thermally bonded to each other and are formed of the same polymer and exhibit substantially the same melting temperature. The fabric is produced by melt spinning an amorphous crystallizable polymer to form two components having different levels of crystallinity. During spinning, a first component of the polymer is exposed to conditions that result in stress-induced crystallization such that the first polymer component is in a semi-crystalline state and serves as the matrix or strength component of the fabric. The second polymer component is not subjected to stress induced crystallization and thus remains in a substantially amorphous state which bonds well at relatively low temperatures. In a bonding step, the fabric is heated to soften and fuse the binder component. Under these conditions, the binder component undergoes thermal crystallization so that in the final product, both polymer components are semi-crystalline.

    摘要： A nonwoven web material that contains fibers formed by compounding at least one polymer with a tackifier is provided. The nonwoven web material can be used as a wipe or tack cloth and can exhibit a dust holding capacity of at least about 10 grams/m2 and a lint potential of less than about 5 fibers/cm2. In addition to containing a tackifier that is compounded with the polymer(s) used to form the fibers of the web, the nonwoven web material can be textured, post-bonded, apertured, or treated with elemental fluorine gas to further improve its dust holding capacity and minimize lint production. In addition, the nonwoven web material leaves minimal residue after contacting a surface.
