摘要： The invention concerns regenerated celluloses which are made flame-retardant and contain at least one compound of formula (I). The invention also pertains to the use of compounds of formula I as flame retardants specifically for regenerated cellulose and a process for modifying regenerated cellulose characterised by the addition of compounds of formula (I) or a dispersion containing these compounds.

摘要： In order to produce a cellulose moulded body, a solution of cellulose in a tertiary amine oxide is moulded in the warm state and the solution thus moulded is fed into a precipitation bath after coding to precipitate the cellulose contained therein. Coding takes place immediately after moulding and is done preferably by blowing air horizontally onto the cellulose moulded body. The process according to this invention facilitates spinning of the cellulose solution with a high yarn density while preventing jamming of the spun yarns when leaving the spinning nozzle. It also allows, despite the high yarn density, a large air gap to be left between the spinning nozzle and the precipitating bath, which leaves adequate time to modify the textile characteristics of the yarns by drawing them as they leave the spinning nozzle.

摘要： Afin de fabriquer des éléments moulés cellulosiques, on moule à chaud une solution de cellulose dans un oxyde tertiaire aminé. La solution moulée est introduite dans un bain de précipitation, afin de précipiter la cellulose contenue, la solution moulée, chaude étant refroidie avant d'être introduite dans le bain de précipitation. Le refroidissement s'opère immédiatement après le moulage et consiste de préférence à souffler de l'air horizontalement sur les éléments moulés cellulosiques. Selon l'invention, le procédé permet de filer la solution de cellulose avec une haute compacité des fils, sans que les fils ne se collent pour autant après être sortis de la filière. Ce procédé permet en outre, malgré la haute compacité des fils, de laisser un grand intervalle d'air entre la filière et le bain de précipitation, ce qui donne ainsi suffisamment de temps lors du processus de filage, pour influer sur les caractéristiques textiles des fils par étirage en sortie de la filière.

摘要： The invention relates to novel colored cellulosic shaped bodies, especially fibers or films, that comprise a colorant which contains heavy metals and which, according to the cited thermostability test, decreases the increasing temperature of a solution of cellulose in a tertiary aminoxide by a maximum of 10 °C, in particular, by a maximum of 5 °C. The inventive shaped bodies can be produced according to the aminoxide method.

摘要： The invention relates to a method for producing cellulose fibres. According to said method, a solution of cellulose in a tertiary amino oxide is extruded through the spinning holes of a spinneret and the extruded filaments are fed into a precipitation bath whilst being drawn via an air gap. The filaments are exposed to a gaseous stream in the air gap. The invention is characterised in that the temperature (T) of the gas prior to the contact with the filaments is represented by the formula: 60 °C
