摘要： A first object of the present invention is constituted by regenerated cellulose based materials, in particular those selected from cellular cellulose materials, fibers, filaments, sheets, textiles and non-woven materials. They contain an effective quantity of at least one chemical agent which improves the resistance of the material to bleach; the chemical agent containing in its structure at least one nitrogen atom .alpha. to a carbon atom and being fixed by at least one covalent bond to the cellulose lattice and/or being trapped in said lattice. Further objects are constituted by the use of chemical agents to improve the resistance to bleach of regenerated cellulose based materials, in particular sponges, and a process for the preparation of these materials.

摘要： A pad which can be abrasive, scouring or both, is formed as a block of foam between two nonwovens. The foam is a polyurethane foam and the nonwovens are based on a mixture of polyamide and polyester fibers. The polyamide fibers have physical properties similar to those of the polyurethane foam. The nonwovens and the foam block are bonded together at their periphery by thermal-welding. The pad can be coated with abrasive fillers. It can also be used for scouring delicate surfaces when it contains little or no abrasive fillers.

摘要： The present invention provides a process for producing alveolar cellulosic products (sponges, sponge-cloths, etc.) from a cellulosic raw material, the process comprising:at least partially dissolving a cellulosic raw material in an intrinsic solvent for cellulose;incorporating an effective quantity of at least one pore-forming agent into the resulting mixture, with mixing; said pore-forming agent(s), being compatible with the cellulosic mixture, being capable of generating macro- and micro-pores when it/they is/are actuated;gelling the homogeneous dough thus obtained;treating said gelled dough under conditions in which the cellulose precipitates out and the pore-forming agent(s) present are actuated.The process is an advantageous alternative to the viscose process which is a polluting process. The properties of the products obtained are completely similar to those of products obtained using the viscose process. The (novel) products form part of the invention.

摘要： An abrasive and/or scouring pad, comprising a core of foam between two nonwovens, wherein the core is a polyurethane foam and the nonwovens are based on a mixture of polyamide and polyester fibers. The polyamide has physical properties similar to those of the polyurethane foam. The nonwovens and the foam are bonded together at their periphery by thermal-welding, either directly, or by two layers of heat-fusible or heat-softening material placed on either side of the foam.
