Ballistic resistant materials having improved strength and lighter weights. More particularly, improved ballistic resistant fabrics produced from drawn, high modulus fibers having a reduced fiber diameter and improved physical strength properties, without changing other properties such as fiber chemistry, binder resin type and binder resin content. The fabrics incorporate low denier per filament monofilament fibers, low denier per filament multifilament fibers, or a combination of low denier per filament monofilament fibers and low denier per filament multifilament fibers in a specialized fabric construction to form fine fiber layers and fabrics having enhanced strength and fiber areal density without altering the fabric weight, or having reduced fabric weight without a corresponding reduction in ballistic performance.

The invention relates to preparation methods of non-woven materials and particularly relates to a preparation method of regenerated leather. The preparation method comprises the following steps: sequentially extracting leather fibers, blending materials, distributing the materials, maintaining slurry, automatically draining water, dynamically pressing and dehydrating, flatly pressing and moulding at high pressure, drying, cutting edges, coiling, carrying out surface-treating, coating or moving a film to prepare a continuous broad product, wherein the fiber extraction step comprises the following steps: smashing leather and extracting fibers and putting the fibers in water and soaking; the material blending step comprises the following step: putting the soaked leather fibers and a chemical assistant in a stirring barrel to be uniformly stirred; the slurry maintaining step comprises the following step that the blended slurry is distributed on a conveyer belt to be fed above a slurry maintaining device to accomplish the polymerization reaction to form a basic form of leather blank slurry; the dynamically pressing and dehydrating step comprises the following step: pressing on the leather blank slurry through a flat pressing disc of a dynamic flat pressing device and squeezing water by means of weight of the flat pressing disc; the step of flat pressing and moulding at high pressure comprises the following step: pressing the leather blank to be moulded by an upper pressure plate of a hydraulic press which descends. The preparation method provided by the invention adopts a simple process flow, is low in cost, high in production efficiency, good in product quality, and wide in application range and has energy-saving and environment-friendly effects.

A benzoxazolium ion compound represented by the following formula X, a sizing agent comprising the compound, a preparation method and use thereof. The chemical structure of the benzoxazolium ion compound represented by formula X is similar to that of PBO fiber, which is beneficial to improve the compatibility of sizing agent and PBO fiber, and its preparation process is simple and easy to operate. The sizing agent overcomes the problems of poor compatibility between the existing sizing agent and PBO fibers, the need to use a large amount of flammable and explosive organic solvents in the sizing agent, and the difficulty in effectively covering the fiber surface with nano reinforcements in the sizing agent. The sizing agent uses water as a solvent, is green and efficient, is simple to prepare, and is environmentally friendly, and the sizing agent can not only maintain the original tensile strength of the PBO fiber, but also significantly improve the IFSS of the composite material.

The invention relates to coating and in particular relates to anticorrosion antistatic coating and a preparation method thereof. Raw materials of the anticorrosion antistatic coating comprise a film forming material, nano metal fibers, chemical antirust pigments, fillers and auxiliaries, wherein metal level of the nano metal fibers is lower than level of steel. The anticorrosion antistatic coating has the beneficial effects that nano zinc oxide fibers are adopted; the defect that nano zinc oxide can be easily agglomerated and is difficult to disperse is overcome; conductive fibers have small diameter and great length-diameter ratio, so that a small amount of conductive fibers can form a conductive network structure in coating, and influence on other properties of the coating can be reduced; and contradiction between static conductivity and corrosion prevention property of the coating in the traditional concept is surmounted, and the paint has two functions, namely corrosion prevention and static conduction.
