开发羊绒细号纱针织产品的研究

为了开发细号羊绒纱针织产品，选用不同线密度的羊绒纱、棉纱、Ｔ／Ｃ混纺纱、涤纶低弹丝和丙纶长丝在单面圆形纬编机上进行了编织试验。作了上机对比及交织试验，测出了各纱线的强度、最大伸长率、对成圈机件的摩擦系数、最大喂纱张力、最小最大线圈长度。最大允许喂纱张力及最大最小线圈长度之差可综合评价线线的可编织性。羊绒纱的摩擦系数普遍较大，而其强度还不及棉纱的一半，最大允许喂纱张力仅为涤纶纱的１／５。羊绒纱的最小线圈长度为２．８～３．５ｍｍ，最大线圈长度能够测出，说明羊绒纱的可编织性较差。试验表明，用单面纬编机生产以羊绒为正面添纱、交织纱在织物反面的添纱组织，具有羊绒效果且服用性能良好。为了顺利地进行生产，对编织工艺、成圈过程中各阶段纱线的受力情况、上机工艺参数、机器选择和染色工艺等作了分析。

绒山羊曲细精管生殖细胞的长期培养和精子发生过程的观察

哺乳动物精子发生过程是生殖生物学的重要研究课题之一.为了开展对山羊精子发生过程的研究,我们首次建立了绒山羊睾丸生殖细胞原代培养方法.原代生殖细胞和支持细胞(Sertolicells)由绒山羊睾丸曲细精管组织块产生,在体外共培养超过三个月.在共培养期间,观察到绒山羊的精原干细胞分化为精母细胞和精子细胞的形态变化过程.这一方法的建立为山羊精子发生过程的研究和应用打下了基础.实验结果显示,在没有添加任何生长因子的条件下,绒山羊睾丸生殖细胞长期增生分化,不断产生精子细胞.这一结果暗示了组织块和共生的支持细胞为生殖细胞的增生和分化提供了营养因子和调节因子.生成的游离精子细胞最后全部死亡,暗示这一共培养体系不能提供变态过程所需因子.

Low Temperature Dyeing and Shrinkage-Resistance Finishing of Wool by Composition of Salt-Ammonia and Enzyme Treatment

Wool top and knitted fabric were treated with ammonia in the presence of sodium chloride （salt-ammonia process）. The effectiveness of salt-ammonia process traditionally used as pretreatment for low temperature dyeing has been investigated for conferring shrink-resistance of wool. The pretreatmont of salt-ammonia process followed by enzymatic treatment has been proved that contribute to not only the enhancement of dyeing behavionr but also shrinkage-resistance in the present studies. A novel composition of salt-ammonia pretreatment, oxidized and reduced treatment as well as protease modification was recommended to achieve low temperature dyeing and shrinkage-resistance of wool. At the same time, the process conditions were optimized by orthogonal array and assessed by dye uptake rate, weight loss and area shrinkage. Laboratory experiments showed that the knitted fabric treated according to optimized conditions of the combined process, achieved not only improvement of dye abilities but also the strict requirement of machine-washable, representing a possible alternative to chlorination.

Determining Compatibilities of Reactive Dyes in Pad Dyeing

Compatibilities of reactive dyes were conventionally shown by exhausting curves. But the change of proportion of dyes in padding dyebath was difficult for pad dyeing to be described by these curves. In this paper, a kind of simulation of pad dyeing process was used to determine dyestuff compatibility in pad dyeing for ramie and linen fabrics. Seven reactive dyes were divided into three groups and tested. The group with Cibacron Yellow C - 2R, Red C - R, and Blue C - R showed very good compatibility both for ramie and linen, and the other two groups of dyes gave out correspondingly low compatibilities in the pad dyeing tests. The results of the method for determining the compatibility of dyes displayed good consistency with the actul pad dyeing process.
