    摘要： A process and apparatus for guiding a continuous moving tow in synthetic fiber manufacture. The profile (the thickness distribution and width) and the position of the tow are continuously sensed in a non-contact manner and an appropriate electrical signal is generated. This electrical signal is used to control the profile and the position of the tow in such a way that its profile and position stay within predetermined target value ranges. The tow geometry is preferably sensed using a CCD camera, while the tow geometry is controlled using tow-engaging deflecting means. In this way it is possible to optimize tow profile and position, for example for entry into a stuffer box (FIG. 1).

    摘要： A method monitors and measures the uniformity of tows with mechanical sensing elements in the course of production on a tow line. The tension of the running tow is measured upstream of a transport roll arrangement and is utilized as a measure of the uniformity of the tow. Irregularities in the tow result in tow tension determination outside a predetermined tension range, and when the determined tension measurement is outside that range the irregular tow portions are remove. Also, the frequency of tow tension determination outside a predetermined range may be used as an indication of tow quality and for removing substandard tows.

    摘要： Recycling materials comprising cellulosic and synthetic fibersDescribed is a process for recycling materials comprising fiber mixtures comprising cellulose fibers, comprising the steps of:i) providing fiber mixtures comprising cellulosic fibers and fibers composed of synthetic polymers, andii) subjecting these mixtures to a microbial hydrolysis in which the cellulosic fibers are completely degraded.The process makes it possible in particular to separate fiber mixtures. For this, the microorganisms and the hydrolyzate are removed in a conventional manner following step ii), and the remaining synthetic polymers are carried off in a conventional manner to be further recycled.

    摘要： A fiber or filament of a swellable polymer of high tensile strength is made by spinning a polymeric raw material which is produced by agitating a suspension of solid particles of an acrylonitrile polymer in dilute sulfuric acid having an acid concentration between 40 to 50 percent by weight until the polymer is hydrolyzed to an extent that it contains from 10 to 30 percent by weight of carboxyl groups such that sticking of individual particles of the polymer to one another is avoided.

    摘要： The invention relates to flame-retarding filaments and fibers and a process for the manufacture thereof. The filament-forming substance is a mixture of from 20 to 70 weight % of an acrylonitrile copolymer A containing at least 80 weight % of acrylonitrile units and from 0.3 to 20 weight % of other units copolymerizable with acrylonitrile, and from 80 to 30 weight % of an acrylonitrile copolymer B containing from 50 to 75 weight % of acrylonitrile units, from 25 to 45 weight % of vinyl chloride and/or vinylidene chloride units and from 0 to 5 weight % of other units copolymerizable with acrylonitrile.The filaments and fibers have a boil-off shrinkage of at least 20% and a knot strength of at least 10 cN/tex and are obtained by spinning the turbid solutions of the copolymer mixture, which however do not separate into components, in an aprotic solvent, and drawing of the filaments in a moderate ratio.
