    • An open-end spinning arrangement having a yarn withdrawal nozzle (10), by means of which the yarn is withdrawn form its transition zone within the spinning rotor and is rollingly and slidingly deflected while circulating in contact with the yarn withdrawal nozzle, additionally imparting a false twist. The yarn withdrawal nozzle has a depression (24), which is abruptly offset in the circulating direction of the yarn, by which the yarn loses contact with the yarn withdrawal nozzle (10) in the withdrawal direction of the yarn and over an angular area a of at least 10 degrees. Each time the rotating yarn tail sweeps over this depression, the false twist is completely interrupted and the actual twisting of the yarn at the yarn withdrawal nozzle (10) is cancelled. Yarns spun by means of such yarn withdrawal nozzles (10) have a looser yarn structure and a clearly reduced number of wrap fibers, and make the employment of rotor-spun yarns possible in applications in which preferably voluminous and soft yarns are processed.
    • 一种具有脱纱嘴(10)的开放式纺纱装置,通过该纱线从纺纱转子内的过渡区域取出纱线,并在与纱线抽出嘴接触的同时循环地滚动并滑动地偏转,另外赋予纱线 假捻。 脱纱喷嘴具有在纱线的循环方向上突然偏移的凹部(24),通过该凹部,纱线在纱线的抽出方向上与脱纱嘴(10)失去接触,并且在角度范围a 至少10度。 每当旋转的纱线尾巴扫过该凹陷时,假捻完全中断,纱线在退纱嘴(10)处的实际扭转被取消。 通过这种纱线抽出喷嘴(10)纺丝的纱线具有更松散的纱线结构和明显减少的包裹纤维数量,并且使用转子纺纱线的可能性在其中处理优选大量和软纱线的应用中是可能的。

    • The present invention relates to silicone (meth)acrylate particles, to a process for preparing such silicone (meth)acrylate particles including the steps of: a) obtaining an emulsion composed of water and an organic phase comprising organopolysiloxanes modified terminally and/or laterally with acrylate groups, and b) polymerizing the inner phase to completion by means of a free-radical initiator, the free-radical initiator being added to the outer phase (aqueous phase) in a concentration of 0.1 to 40% by weight based on the inner phase, and to the use of the particles alone or in a mixture with further particles, pigments and/or further customary additives in the form of powders or dispersions in coating, adhesive or sealant materials, in polymers, in defoamers, in wetting and levelling aids, in cosmetic or pharmaceutical formulations and care products, in cleaning and detergent compositions, or in applications for modifying the interface properties of solid and liquid substrates, for example tactile properties, hydrophobization, or sliding and/or release properties.
