Abstract: Improved processes are provided for treating a porous substrate (especially a fabric) to produce novel internally coated porous materials. During treatment, a curable thixotropic material and one or modifying materials are applied to the porous substrate as an impregnant. The treatment imparts specific properties to the end product material. Selection of the modifier material is based on the particular end use application. Sufficient energy is directed to the impregnant and porous substrate to cause the impregnant to flow into the porous substrate and force the modifier to specific positions within the substrate.

Abstract: A photoreflective sheet comprising a resin foam sheet, a metal foil with an uneven shape in section laminated on a face of the sheet, and a base cloth laminated on the other face of the sheet is described. For agricultural use, laying the sheet under trees in orchards or hanging it from branches facilitates the growth and coloration of fruit even if the fruit are not well exposed to the sunshine, since the metal foil reflects sunshine in all directions. Further, a certain sustained-release preparation coating the back of the resin foam sheet protects fruit from certain pests such as animals, birds, insects, fungi and herbs. The middle resin foam sheet prevents a rise in temperature and dryness in soil. Also, the sheet can buffer the impact that the fruit dropped by a strong wind or heavy rain would receive. Consequently, the sheet provides an excellent effect so that damage to the fallen fruit is limited to the lowest level.

Abstract: Disclosed herein is a repellent-treated, barrier coated nonwoven web. Nonwoven webs with small fiber and pore sizes can often be surface coated with a barrier coating such as latex to form a nonwoven which will act as a barrier to liquids. Surface coating of nonwovens having larger pores and fibers is more difficult as the coating often sinks into the thickness of the nonwoven web. The material of the present invention is a larger fiber/pore nonwoven web which will permit surface coating to form a material which has a good hand and cloth-like feel while also acting as a barrier to liquids. Such a material has a wide variety of applications including, but not limited to, personal care products, surgical drapes and gowns and other applications requiring barrier properties.

Abstract: A method and material for the manufacturing or retrofitting of fluid transport systems. The material chosen for the lining, or the pipe itself, will be selected based on physical properties such as a high impact strength and a low coefficient of friction. The low coefficient of friction will be essential to prevent the initial adhesion of foreign substances to the inner surface of pipes. In particular, an improved pipe composite will be useful in the lining or construction of water intake pipes where there is a well-recognized problem of the buildup of foreign substances including algae and other marine microorganisms. Therefore, by preventing buildup, the present invention will provide a more economical and efficient method to maintain the overall piping system.
