Abstract
A process for the treatment of cellulosic textile materials comprising the following successive steps: effecting grafting of the cellulose textile material with a monomer which, when formed into a polymer, has the characteristics of an elastomer at ambient temperature; effecting irradiation treatment by ionizing radiation of the grafted cellulose material so as to achieve cross-linking of the grafts formed, thus leading to permanent crease resistant properties; and effecting post-irradiation treatment by storage enabling the cross-linking to be completed.
Claims13
A process for the treatment of cellulosic textile materials comprising the following successive steps:
- a. grafting the cellulose textile material with an acrylic acid ester monomer or a mixture thereof with a comonomer copolymerizable therewith in the presence of a chemical initiator agent, with a grafting ratio of a least 6% in relation to the weight of the starting cellulose material;
- b. effecting irradiation treatment by ionising radiation of the grafted cellulose material obtained in the preceding stage with an irradiation dose of from 0.5 Mrads to 10 mards;
- and
- c. effecting post-irradiation treatment by storage of the irradiated product for a period of from 1 day to 14 days at ambient temperature.
