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:
A phosphorus-containing polymer comprises a plurality of phosphorus atoms, wherein about 75% or more of the phosphorus atoms in the phosphorus-containing polymer are present in phosphine oxide moieties. An article comprises a textile material having at least one surface and a phosphorus-containing polymer disposed on a least a portion of the surface, wherein the phosphorus-containing polymer comprises a plurality of phosphorus atoms, and wherein about 75% or more of the phosphorus atoms in the phosphorus-containing polymer are present in phosphine oxide moieties.
Abstract:
A method for making a belt or rope includes providing a plurality of cords; engaging the plurality of cords with a jacket; and providing an organic-containing material to at least one of the cords and the jacket.
Abstract:
This invention relates to a method for fireproofing textiles based on a composition having two components comprising: a component A comprising at least one phosphorous compound; and a component B comprising urea and at least one pH buffer, optionally with an oxidising agent. Said method for fireproofing textiles includes the steps of immersing said textiles in said composition, and of heating, oxidising and then washing said textiles, which then have excellent human-ecological, comfort, and durable fireproofing properties.
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:
A flame-proof finishing agent which comprises a phosphorus compound represented, for example, by the following formula (4): (4) and a method for flame-proof finish which comprises immersing a polyester fiber fabric or the like in a treating solution containing the flame-proof finishing agent and subjecting the resulting mixture to a heat treatment at a predetermined temperature, to thereby fix the flame-proof finishing agent on the polyester fiber fabric or the like. The fiber having been flame-proof finished by the above method exhibits satisfactory flame retardancy, which has been imparted by a post-treatment, with no use of a halogenated compound, while retaining satisfactory resistance to washing.
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.
