| abstract | 1326628 Stabilisation of textile fibres COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 6 Oct 1970 [7 Oct 1969] 47535/70 Heading D1P A method, for treating a textile material to improve its resistance to and recovery from deformation comprises heating the material in an atmosphere in which the relative humidity is between 50 and 95%, preferably 65 to 90%, at a temperature of from 30‹C to 150‹C, preferably 40 to 150‹C for a period of from 5 minutes to 2 weeks, preferably 5 minutes to 3 days, thereby to improve the resistance to and recovery from wrinkling of the material; and treating the material with at least one multifunctional compound which is capable of undergoing a reaction with the material under conditions which do not deanneal the material. Preferably the temperature is from 100 to 120‹C. and the heating period is from 10 minutes to 4 hours. The term multifunctional compound refers to compounds small enough to deffuse into the fibre, which possess at least two reactive sites or groups and is capable of undergoing reaction with itself, with another such compound and directly or indirectly with the substance of the textile fibre giving new chemical linkages. The multifunctional compound may be applied to the textile material before, during or after exposure of the textile material to the annealing conditions is the elevated temperature and the increased relative humidity. Furthermore two or more multifunctional compounds or two or more reactants which together give rise to a multifunctional compound may be applied. It is possible to apply one multifunctional compound at one stage of the procedure and another compound at a subsequent stage, forming a three dimensionally cross-linked polymeric structure involving reactive sites in the textile fibres. The multifunctional compound contains at least two reactive groups selected from formyl (aldehydo), epoxy, aziridinyl, O- and N-methylol or alkylmethyl activated C-methylol, isocyanato and isothiocyanato, displaceable halogen, vinyl and activated 2-hydroxylethyl and O-derivatives thereof, sites capable of generating free radicals on irradiation, hydroxyl, amino, carbamyl, carboxyl, aliphatic and heterocyclic imino, imido and mercapto. Preferably the first reagent is a compound selected from melamine and its hydroxymethyl derivatives (particularly monomethylolmelamine), resorcinol, pyrogallol, #- resorcyl aldehyde, phloroglucinol, n-phenylenediamine and p-phenylenediamine. The second reagent is formaldehyde, either in its gaseous form or as paraformaldehyde. Preferably 1 to 10% of both reagents are used (based on the weight of the material). Materials treated by the method are cotton, wool, silk, nylon and all polymer materials which can undergo molecular rearrangement. |
