一种调温竹粘胶纤维及其制备方法
摘要：
本发明提供了一种调温竹粘胶纤维。本发明还提供了一种调温竹粘胶纤维的制备方法，包括：提供质量浓度为1％～20％的相变微胶囊胶体溶液；将竹纤维素浆粕经浸渍、压榨和粉碎处理后，得到碱纤维素；将所述碱纤维素依次经过老成工序、黄化工序、溶解工序、混合工序、脱泡工序、过滤工序、纺丝工序和后处理工序后，得到调温竹粘胶纤维，在进行黄化工序、溶解工序、混合工序或纺丝工序时，向物料中加入所述相变微胶囊胶体溶液，黄化工序包括以下步骤：向经过老成工序的碱纤维素中加入碱液进行碱化，碱化温度为15℃～25℃；碱化结束前10min～15min将碱纤维素调温至黄化反应温度，碱化结束后向所述碱纤维素中加入二硫化碳进行黄化。
摘要（英）：

The invention provides temperature-adaptable bamboo pulp fibers and a preparation method of the temperature-adaptable bamboo pulp fibers. The method comprises the following steps: providing phase-change microcapsule colloid solution with mass concentration of 1-20%; impregnating, squeezing and grinding bamboo cellulose pulp to obtain alkali cellulose; and ageing, yellowing, dissolving, mixing, defoaming, filtering, spinning and post-processing the alkali cellulose to obtain the temperature-adaptable bamboo pulp fibers. During the yellowing process, dissolving process, mixing process or spinning process, the phase-change microcapsule colloid solution is added to the material. The yellowing process comprises the following steps: adding alkali liquor to the aged alkali cellulose for alkalization, wherein the alkalization temperature is 15-25 DEG C; and adjusting the temperature of the alkali cellulose to the yellowing reaction temperature 10-15min before completing alkalization and adding carbon disulfide to the alkali cellulose for yellowing after completing alkalization.
