    Abstract: The present invention relates to a process and a device for chlorine-free shrinkproof treatment of a wool raw material and an article thereof. In particular, the process of the present invention comprises the steps of a chlorine-free shrinkproof treatment, washing with water, protease inactivation, a softening treatment, dehydration, drying and the like, wherein a chlorine-free catalysis system consisting of a protease, a specific organic phosphine compound and the like is selected, removing the scale layer on the surface of wool fibres cooperatively and efficiently and modifying the scale layer so as to improve the shrinkproof performance of wool articles. The process of the present invention can completely replace the chloridisation shrinkproof method in the prior art, and is not only environmentally friendly, but also has low requirements for equipment, can be operated continuously and is suitable for large-scale industrial production.

    Abstract: La présente invention concerne un procédé d'ignifugation de textiles basé sur une composition à deux composants comprenant :
    • un composant A comprenant au moins un composé phosphoré ; et
    • un composant B comprenant de l'urée et au moins un tampon pH, avec éventuellement un agent oxydant.
    Ledit procédé d'ignifugation de textiles comprend les étapes d'immersion desdits textiles dans ladite composition, de chauffage, d'oxydation puis de lavage desdits textiles qui présentent alors d'excellentes propriétés humano-écologiques, de confort, et ignifuges sur la durée.

    Abstract: Modified wool having improved shrink-proofing property is obtained by a two step process in which raw material wool is first immersed in a first aqueous bath containing a water-soluble organic phosphine and is then immersed in a second aqueous bath containing a modifying agent selected from epoxy compounds, ethyleneimine compounds, urea, substituted urea compounds, thiourea, substituted thiourea compounds, alkylene carbonates, unsaturated carboxylic acids, derivatives of unsaturated carboxylic acids, unsaturated nitriles, unsaturated alcohols, esters of an unsaturated alcohol, sulfonic acid salts having a vinyl group, cyanic acid salts, nonionic surfactants of a poly(alkylene oxide) type, salts of sulfates of the nonionic surfactants and silane coupling agents having a vinyl group. The treatment may also be performed by a one step process in which wool is immersed in an aqueous bath containing the above phosphine compound and a modifying agent selected from the above.
