摘要： The invention provides a process for the manufacture of viscoses from hemicellulose-containing cellulose pulps without requiring dialysis equipment. By addition of substances having a cross-linking or blocking action on the active groups of hemicellulose to the pulp before or during steeping it is possible to reduce the use of NaOH and CS.sub.2 in the manufacture of viscoses.The viscoses so obtained are distinguished by good filterability and low content of compounds causing formation of H.sub.2 S in the spinning process.
摘要翻译：本发明提供了一种从含有半纤维素的纤维素纸浆制造粘胶而不需要透析设备的方法。通过在渗透之前或期间将半纤维素的活性基团上交联或阻断作用的物质添加到纸浆中，可以减少在制造粘胶中使用NaOH和CS2。如此获得的粘胶通过良好的过滤性和低含量的化合物在纺丝过程中形成H 2 S来区分。

摘要： A continuous feed of alkali cellulose (AKC) is partially xanthated, and then dissolved and further xanthated to form a viscose solution, while passing continuously through a series of connected reactors and slurry vessels, wherein slurries of carbon disulfide (CS.sub.2) and alkali metal hydroxide are maintained. The AKC feed to the system may be shredded crumbs from any standard alkali cellulose system, to shredded crumbs from a continuous sheet steeping mercerization system. A portion of the xanthate AKC (cellulose xanthate) may be recycled to the various slurry vessels or zones.

摘要： The present invention describes a method for the production of a spinning dope composition, said method comprising a homogenization involving vigorous mixing of a cellulosic pulp material in alkali solution, vigorous mixing implying supplying a power density to agitators used in the homogenization step of at least 150 k W/m3 (k W supplied to agitators per mixed unit of liquid volume), and thereafter a dissolution involving mixing of the cellulosic pulp material in the alkali solution to obtain a spinning dope composition, wherein the power density supplied to agitators used in the dissolution step is maximum 75 k W/m3 (k W supplied to agitators per mixed unit of liquid volume); and wherein the cellulosic pulp material in alkali solution is kept at a temperature of less than 0° C. during the homogenization and during at least part of the dissolution. The present invention is also directed to a system intended for the production of a spinning dope composition.

摘要： A process for the continuous filtration and aging of a viscose solution comprising xanthated alkali cellulose (XAC) is described wherein the XAC is continuously passed in a downstream direction through a series of aging tanks and a series of filter means. The aging tanks are so designed and arranged that the viscose solution is never partitioned into batches, as necessitated by common manufacturing systems, but constitutes a continuous, uninterrupted stream throughout aging filtration, deaeration and spinning. The filter means, standard plate and frame filters, are designed and installed in such a manner that the number of filter changes, or redressings, are substantially reduced in the aggregate, without increasing the number of filters now used in a standard plant, or sacrificing viscose quality. This results in less process interruption, loss of product, and less potential environmental pollution.
摘要翻译：描述了包含黄原酸碱纤维素（XAC）的粘胶溶液的连续过滤和老化的方法，其中XAC沿下游方向连续通过一系列老化罐和一系列过滤装置。老化罐是如此设计和布置，粘胶溶液从来没有按照普通制造系统的要求进行批量分批，而是在整个老化过滤，脱气和旋转过程中构成一个连续不间断的流。过滤器装置，标准板和框架过滤器被设计和安装成使得过滤器的数量变化或纠正在总体上显着减少，而不增加现在在标准设备中使用的过滤器的数量，或牺牲粘胶质量。这样可以减少流程中断，产品损失，减少潜在的环境污染。

摘要： A solution of cellulose or cellulose derivative suitable for spinning, extruding or other shaping process is prepared by steeping unaged cellulose or a cellulosic derivative a plurality of times, consecutively, subsequently shredding and then aging prior to xanthation or the like. The concentration of alkali metal hydroxide of the solution used for resteeping is lower than that in the first steeping step. The process produces a viscose with less carbon disulfide than the conventional process without reduction in yield of cellulose. The process is adaptable for steeping in conventional press steeping apparatus or slurry steeping apparatus.
