Abstract: Material for antiballistic protective clothing comprising in a single-layer or multi-layer package or laminate at least one layer of a flat structure containing an organic dilatancy agent This flat structure is particularly suited for a trauma package in an antiballistic package. The flat structure with a dilatancy agent results in a significant improvement in the antiballistic effect and, in particular, a reduction in the trauma effect. The material finds special application for bullet-proof and splinter-proof vests and correspondingly for helmets. Moreover, the material of the invention can be used in clothing protecting against impact.

Abstract: The present invention relates to thermoplastically formable composite materials of reinforcing fibers in a polyamide 12 matrix, characterized in that the polyamide 12 matrix consists of anionically polymerized laurin-lactam maximally containing 15 weight-% of co-monomers and selectively additives which are determined on the basis of production, processing and use. The invention furthermore relates to a process for producing these composite materials, in accordance with which an activated anionic lactam 12 melt is prepared, which penetrates the fiber arrangement in the liquid state, so that it forms the matrix for a shaped body, the activated melt is final-polymerized under the effects of temperature and pressure in a mold or a tool in such a way that the shape is achieved, and the pre-formed part is subjected to an after-shaping step under the effects of pressure and temperature, if desired.
Abstract: Functional fiber products are provided.The functional fiber products are those adhered thereto a protein containing 20% to 40% by weight of serine as an amino acid component and those adhered thereto sericin and deacetylated chitin.
Abstract: The invention provides a dry, disposable, polymeric product having sustained-release anti-microbial activity, the product consisting essentially of a polymeric material selected from the group consisting of fibers, fabrics, sheets, films and other stable woven, non-woven and knitted materials prepared from natural, man-made and synthetic polymers and an amine salt anti-microbial agent, the anti-microbial agent being incorporated in the polymeric material without an intermediary adhesive, carrier or linking agent and being releasable therefrom in anti-microbially effective amounts for a period of at least three days upon the product being brought into contact with a moist surface.

Abstract: A kit for bathing a patient or for personal bathing includes a sealed polyethylene bag containing a plurality of cloths impregnated with a cleansing solution. The cloths are a needle-punched blend of cotton and cellulose acetate for softness and low cost. Furthermore, an anti-microbial agent is carried by the cellulose acetate to prevent the growth of bacteria, yeast and fungus and the package carries another anti-microbial solution as a preservative. The cleansing solution is a non-ionic, nonrinsing mixture of surfactants, emollients or humectants, vitamin E and de-ionized water. The kit is heated and then each cloth is used on a different part of the body and disposed of after use to prevent cross contamination.

Abstract: A nonwoven fabric for a liner of a floppy disk is characterized by a binder which is applied to the fibers of the nonwoven fabric. The binder comprises (a) an emulsion obtainable from a polymerizable unsaturated monomer having a functional group and other polymerizable unsaturated monomers capable of undergoing copolymerization with said polymerizable unsaturated monomer, and (b) a melamine compound having a methylol group.
