Abstract
Cellulose is treated with a bisglycidyl ether of a polyhydroxy phenol in the presence of an alkali metal hydroxide and heated, whereby cross-linkages are formed between the cellulose chains. The cellulose to be treated may be in the form of regenerated cellulose or cotton fibre or cloth. The ether may be applied in solution in an organic solvent, the cellulose having been pretreated with a caustic alkali solution. Alternatively the ether may be applied in an aqueous caustic alkali-containing emulsion. Specified polyhydroxy phenols from which the ethers are prepared are hydroquinone, resorcinol, phloroglucinol, dihydroxynaphthalene, bromohydroquinone, chlorohydroquinone, resorcylic acid, nitroresorcinol, vinylhydroquinone, pentadecyl resorcinol, hydroxy salicyl anilide and azo-substituted-hydroquinone or -resorcinol. When the cross-linkage contains a free hydroxy group on the aromatic nucleus, subsequent treatment with a diazonium salt may be effected to yield a coloured fibre. The Provisional Specification refers also to the use of bisglycidyl ethers of dially hydroquinone and 4-carboxy-2:4-dihydroxy-pyridine.ALSO:The following bisglycidyl ethers of polyhydriphenols are prepared by reacting the corresponding polyhydric phenol with epichlorhydrin: the bisglycidyl ethers of monobromohydroquinone, hydroquinone, resorcinol, tetrachlorhydroquinone, 5 5-pentadecyl resorcinol, 1,5-dihydroxynaphthalene and phloroglucinol.ALSO:Regenerated cellulose and cotton fibres or fabrics are given a reduced swelling capacity and hence a reduction in their shrinkage characteristics by treatment with a bisglycidyl ether of a polyhydroxy phenol in the presence of an alkali metal hydroxide followed by heating, whereby cross-linkages are formed between the cellulose chains. The ether may be applied in solution in an organic solvent, the cellulose having been pretreated with caustic alkali solution. Alternatively the ether may be applied in an aqueous caustic alkali - containing emulsion. Specified polyhydroxy phenols from which the ethers are prepared are hydroquinone, resorcinol, phloroglucinol, dihydroxynaphthalene, bromohydroquinone, chlorohydroquinone, resorcylic acid, nitroresorcinol, vinylhydroquinone, pentadecyl resorcinol, hydroxy salicyl anilide and azo-substituted hydroquinone or - resorcinol. When the cross-linkage contains a free hydroxy group on the aromatic nucleus, subsequent treatment with a diazonium salt may be effected to yield a coloured fibre. The Provisional Specification refers also to the use of bisglycidyl ethers of diallyl hydroquinone and 4 - carboxy - 2:4 dihydroxy pyridine.
