Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.

A process for manufacturing a costume having semi-rigid costume components, and the costume itself. The semi-rigid costume components are capable of being sewn to fabric to form an integrated costume. An embodiment is shown in which the costume includes a semi-rigid muscular torso suitable for a superhero chestpiece. The sewn rigid component is formed from fusing a layer of fabric to a layer of foam and the resulting laminate is vacuum molded into a three-dimensional shape.

Process for the stiffening of textile or leather materials, includes (a) applying an aqueous polymer dispersion to a textile structure on the basis of a woven or nonwoven fabric, or a leather material; (b) drying the textile structure or leather material; and (c) the stiffening material thus produced is deformed and glued with the textile and leather material to be stiffened, in which an aqueous dispersion of a two-phase, sealable emulsion graft copolymer having a soft phase and a hard phase is applied. The hard phase has a glass transition temperature of Tg of at least 50.degree. C. and includes monomer units such as methyl methacrylate, styrene, diisopropyl fumarate and vinyl chloride. The soft phase has a glass transition temperature Tg of at least 30.degree. C. lower than the Tg of the hard phase, and the soft phase has monomer units such as methyl acrylate, ethyl acrylate, isopropyl acrylate, n-butyl acrylate, t-butyl acrylate, 2-ethylhexyl acrylate, vinyl acetate, vinyl propionate, isopropenyl acetate, vinyl laurate, vinyl esters of saturated, .alpha.-branched monocarboxylic acids having 9 to 10 carbon atoms, ethylene, propylene or 1,3-butadiene.

A specific class of water-borne, water redispersible laminating adhesives is disclosed which is desirable for bonding nonwoven substrates to themselves or to other substrates. The adhesives provide improved bond strength and improved water redispersibility when compared to laminating adhesives currently used for the same purpose. Furthermore, the novel adhesives are much less sensitive to the presence of significant levels of plasticizer than are laminating adhesives currently used, which exhibit reduced water redispersibility when such plasticizers are present in significant amounts. The novel laminating adhesives contain an aqueous styrene/acrylic polymer dispersion prepared by radical-initiated emulsion polymerization of unsaturated monomers in the presence of starch degradation products having a weight average molecular weight range of from about 2500 to 25000 and which are obtainable by hydrolysis in the aqueous phase. The adhesives may contain only the starch-modified, styrene/acrylic polymer dispersion, or may further include other components, such as plasticizers and/or rheology modifiers, when required. The novel adhesives are particularly useful in disposable articles wherein a nonwoven substrate is bonded to a second substrate via a water-borne, laminating adhesive. The disposable articles may include an absorbent core portion disposed between and proximate the nonwoven and second substrate.

The invention relates to a fusible textile product and its method of manufacture. This thermally fusible product, intended particularly for the textile industry of a type comprising on one hand, a woven, knitted or non-woven textile substrate and, on the other hand, points of a thermally fusible material distributed on one of the external faces of the substrate, in particular polymer base. It comprises at least one reactive material and at least one reactive mean suitable for stimulating fixing and developing the reaction between the reactive material and a part of the thermally-fusible material with a view to partially modifying its chemical structure at least at the interface with the substrate, in such a way as to prevent the thermally-fusible material flowing through the substrate when affected by heat, pressure or steam. Method of manufacture of such a product.

摘要:
According to the invention, a novel laminated fabric sheet of excellent air permeability and a method for producing the same are provided. The laminated sheet comprises a first base fabric including spun yarn and having previously been treated with a water and oil repellent, a rubber composition layer formed on the first base fabric and having a multitude of fine air passages therein and a second sheet of base fabric laminated on the rubber composition layer. The base fabric which has been treated with the water and oil repellent prevents the coated rubber composition from reaching roots of whisker fibers of the spun yarn in the base fabric and fine cells are thereby formed around the lower portion of the whisker fibers. Subsequent heating of the laminated sheet of fabrics for curing the rubber composition causes these fine cells to be inflated to form air passages through the cured rubber composition layer. The rubber composition layer includes, as its main ingredient, a product of reaction between liquid diene-polymer having at least two active hydrogen groups in the molecule and polyisocyanate.
摘要:
A sheet material comprises at least three superposed layers (11, 12, 13, 14) each consisting of a plurality of strands (11a, 12a, 13a, 14a) disposed in and completely surrounded by a mass of adhesive so that individual strands of each layer adhere to one another and adjacent layers adhere to each other. Strands in adjacent layers are transversely, and preferably perpendicularly, arranged. A preferred adhesive is curable polyvinyl chloride. Strands in non-adjacent layers may be substantially aligned or may be offset. Strands may have a non uniform or uniform spacing and may be of the same or differing decitex. Material is made by embedding strands in adhesive, placing layers so formed together and thereafter curing the adhesive. The material has greater tear strength in at least one direction than conventional plastics coated woven material having the same yarn content.
