    (54) METHOD FOR TREATING SPINNY MESTERS OF VISCOSE
    (57) The invention relates to the production of viscose dye solutions used to produce fiber. The invention makes it possible to increase the rate of efflux of solutions due to the fact that polyethylene glycol mol. m. 1100000-4500000 in the amount of 0.07-1.0 wt.% in terms of cellulose. 4 tab.
    This invention relates to the production of viscose dye solutions used to produce fiber.
    The purpose of the invention is to increase the rate of outflow of solutions.
    Example 1 The average molecular weight polyethylene glycol indicated in the table below is added to the xanthate solution. jjejiulose in the amount of 1 kg / ton of pulp. The cellulose xanthate solution obtained by adding 35% carbon disulfide B based on the weight of cellulose contained 10% cellulose xanthate calculated on the basis of pure cellulose and 5.7% NaOH. The viscosity of the falling ball of the thresholder was 53 s. After filtration to remove undesirable particles, the solution is forced through the spinning die with a constant pressure drop across the spinneret equal to
    3 ati (3 kgf / cm). The following results were obtained, which are shown in Table. one.
    Example 2. To a solution of cellulose xanogenate, as in Example 1, various amounts of polyethylene glycol with mol. May million. After filtration, the cellulose xanthate solution is forced through the spinneret with a constant pressure drop of 2 atm (2 kgf / cm). The following results were obtained, the data in table 2.
    Example 3. Cellulose xanthate is obtained from pre-hydrolyzed sulphate pulp with an alpha cellulose content of 93%. Sulfate cellulose is subjected to mercerization with 18% NaOH at 20 ° C. Alkaline cellulose is subjected to xanthogenic using sulfur sulfide ate

    sort, taken in quantity based on the weight of the pulp. The resulting solution contained 11% cellulose xantogenate calculated on the basis of cellulose and 6.4 wt.% NaOH.
    Part of the cellulose xanthate solution is mixed with polyethylene glycol having a mol. May 3 (5 ml, in the amount of 1 kg / ton of cellulose (0.1 wt.%), RESTtvors of cellulose xanthate with and without addition were tested for filterability, viscosity for the falling ball and flow rate through the spinner).


    constant differential pressure 15 Molecular 3 of these (3 kgf / cm4). With i-, gl.l ™ poly ethylene glyc mass, million
    this was obtained the following results, presented in table. 3 "
    From these results, it follows that the amount of cellulose xanthate solution through the spinneret is greatly increased by adding polyethylene glycol according to the invention.
    The characteristics of the viscose fiber according to Example 1 were also determined by comparison with the control without the addition of polyethylene glycol. For testing, the viscose according to the invention contained polyethylene glycol having a mol. May, 3,500,000 in an amount of 0.135 by weight of cellulose. The following results are presented in table. k.
    From the above data, it is clear that the characteristics of viscose fiber are not subject to any noticeable effect when high molecular weight polyethylene glycol is added.
    When adding glycols with mol. May to 3000 by a known method, the flow is reduced by 13%, while according to the invention it increases significantly when these
