Abstract
An artificial organic partially degraded hybrid fibre formed of a fibre-forming polymer having a fine structure including crystalline and amorphous regions, contains a hybridizing substance comprising at least one chemically different amorphous polymer capable of disrupting the fine structure of the fibre-forming polymer during fibre formation. The partially degraded fibre has the same weight as the parent undegraded fibre and, when beaten in water, forms fibrils with diameters of the order of from 50 <\>r to 7500 <\>r. The term "hybrid" is defined as a fibre-forming mixture containing a fibre-forming polymer and one or more chemically different amorphous polymers which is or are capable of solidifying during the conditions under which a fibre is formed and is or are capable of disrupting the fine structure of the fibre-forming polymer during the formation of the fibre. The fibres may be composed wholly or partially of natural or synthetic organic high polymers. The fibre-forming polymer may be regenerated cellulose and the chemically different amorphous polymer may be an alkali soluble, water-insoluble hydroxyethyl, hydroxypropyl or carboxyethyl cellulose or it may be a polyacrylate. The hybridizing substance need not be a fibre-forming material per se. When the fibre-forming polymer is regenerated cellulose the partial degrading of the fibres may be effected by treating the fibres with a dilute aqueous solution of hydrochloric or sulphuric acid and the so-treated fibres may be beaten in an aqueous medium or water to fibrillate and disperse the fibres, the fibres may be collected to form a water-laid web and the web may be dried. The dispersed fibres may be mixed with other fibres and the mixture formed into a web, or the dispersed fibres may be separated from the water before mixing them with other fibres and forming a web from the mixture. The hybridizing or extraneous substance is intimately mixed with the spinning liquid which is then spun into filaments and the filaments processed in a conventional manner. The proportion of the hybridizing substance added is preferably about 25 to 75% based on the weight of the fibre-forming polymer. Specification 934,786 is referred to.ALSO:Paper is made from an artificial organic partially degraded hybrid fibre formed of a fibre-forming polymer having a fine structure including crystalline and amorphous regions containing a hybridizing substance comprising at least one chemically different amorphous polymer capable of disrupting the fine structure of the fibre-forming polymer during fibre formation. The partially degraded fibre has the same weight as the parent undegraded fibre and, when beaten in water, forms fibrils with diameters of the order of from 50A to 7500 . The term "hybrid" is defined as a fibre-forming mixture containing a fibre-forming polymer and one or more chemically different amorphous polymers which is or are capable of solidifying during the conditions under which a fibre is formed and is or are capable of disrupting the fine structure of the fibre-forming polymer during the formation of the fibre. The fibres may be composed wholly or partially of natural or synthetic organic high polymers. The fibre-forming polymer may be regenerated cellulose and the chemically different amorphous polymer may be an alkali-soluble, water-insoluble hydroxyethyl, hydroxypropyl or carboxyethyl cellulose or it may be a polyacrylate. The fibre-forming polymer may be nylon. The hybridizing substance need not be a fibre-forming material per se. When the fibre-forming polymer is regenerated cellulose, the partial degrading of the fibres may be effected by treating the fibres with a dilute aqueous solution of hydrochloric or sulphuric acid and the so treated fibres may be beaten in an aqueous medium or water to fibrillate and disperse the fibres, the fibres may be collected to form a water-laid web and the web may be dried.
