摘要:
A substantially flexible, dry matrix, which contains not more than about 3% moisture at room temperature, is impregnated with a water free treatment mixture containing a lipid and a surfactant. In a preferred embodiment, the mixture includes a glycol, a surfactant and a lipid emollient, lubricant, medicament or skin protectant. Methods of manufacturing and using the impregnated matrices are also taught.
摘要:
Carpet material with at least a proportion of uncleaned used carpets is shredded to form a fiber-like wooly mass. The carpet material contains a thermoplastic binder with a low melting point, for example polypropylene, which can be derived from the used carpets or be added. Furthermore, a duroplastically hardening binder, for example phenolic resin, is added to the carpet material. The carpet material is compressed to form the molded part or panel with these two binders, at a temperature which lies above the plasticizing point of the thermoplastic binder, but below the plasticizing point of any other thermoplastic components of the carpet material.
摘要:
A carpet underlay comprising a fibrous nonwoven substrate composed of natural or synthetic fibers having in or on it a repellent finish which makes said substrate substantially imprevious to liquids, and a carpet having an underlay substantially impervious to liquids affixed to the carpet back rendering said carpet substantially impervious to liquids are disclosed.
摘要:
A textile coated with a coating having a multiphase fluorochemical, a cationic material, and a sorbant polymer. A printed image is subsequently placed on the coated textile.
摘要:
A staple fiber for an electret non-woven fabric, which is a polyolefin heat-bonding fiber having 0.05 to 1.0% by weight of an oil adhering thereto, characterized in that the amount of the adhering oil decreases to 0.001 to 0.2% by weight, and that the decrease ratio of the amount of the adhering oil can be at least 60%, under heat treatment for forming the polyolefin heat-bonding fiber into a non-woven fabric and/or under heat treatment of a non-woven fabric formed of the polyolefin heat-bonding fiber.
摘要:
Paperboard having a water-repellant coating which includes a polymer matrix/wax/pigment mixture and is applied to the paperboard as an aqueous formulation. The polymer matrix includes polymer chains which are ionically cross-linked through pendant carboxylic acid groups to provide, together with the wax and pigment components, a substantially continuous, water-repellant film which more readily breaks down under the alkaline conditions of repulping. The coated board also exhibits low slip and resistance to blocking, and is particularly well-suited in corrugated box constructions used in shipping containers for perishable food items such as meats, poultry, fishery products, fruits and vegetables. The pigmented or unpigmented coating formulations are also used as an overcoat over preprinted paperboard surfaces to simultaneously provide scuff and water resistance.
