一、引言目前,在我国的亚麻纺织行业中,由于设备及工艺上的多种原因,导致在梳麻过程中造成许多亚麻短纤维的浪费。那么,如何使这些亚麻短纤维得到充分利用,从而降低成本便成了亚麻纺织行业中急待解决的问题,为了解决这一问题,我厂于1992年对一些亚麻纺织行业进行了考察。发现目前亚麻纺织行业中普遍采用干纺这种工艺来处理亚麻短纤维,也就是将梳下来的亚麻短纤维通过并条,粗纱等过程最终再经过干纺细纱机将其纺成支数较低的纱用于织造麻袋及帆布等,但由于所采用的干纺细纱机都是50年代的老设备,设计上不够完善造成机配件损耗相当… 相似文献

在高档品种的细纱和织物中使用亚麻短纤维是一项非常重要而现实的任务。根据我们的研究,用亚麻短纤维可以纺得高质量的包芯纱,包芯纱中,亚麻短纤维处于外层缠绕在坚牢的化纤芯纱上(卡普隆,拉夫桑,强力粘胶丝等等),通过拈合的方法使其紧固起来。这种细纱可以做为经、纬纱用在一系列重要工业用的亚麻 相似文献

亚麻纤维在脱胶过程中形态结构的变化 总被引:5,自引:1,他引:4
利用扫描电子显微镜研究温水浸渍法脱胶和酶法脱胶过程中亚麻纤维表面形态的变化情况。结果表明:使用这2种方法进行脱胶,纤维表面在脱胶过程中基本上都没有受到大的损伤,最后得到的纤维在表面形态上也无大的差别。采用X射线衍射法研究温水浸渍法脱胶和酶法脱胶过程中亚麻纤维结晶度、取向度的变化情况。结果表明:无论是温水浸渍法脱胶还是酶法脱胶,亚麻纤维的结晶度在脱胶过程中经过一系列的变化,最后都有一定程度的提高,而亚麻纤维的取向度在脱胶过程中自始至终都无明显变化。 相似文献

The goal of this investigation was the interpretation of genetic polymorphism in flax using the random amplified polymorphic DNA (RAPD-PCR) technique in relation to genealogical information and eco geographic origin of the accessions. Protein markers have been successfully applied for identification of ecotypes of cultivated plants and for cultivar identification and registration. However, for intraspecific differentiation in flax effective protein markers have not been found. The DNA markers developed during the recent decades proved to be more efficient in detecting polymorphism in flax. The plant material were 287 accessions from the flax collection at the All-Russian Flax Research Institute (VNIIL) belonging to different botanical and eco-geographical groups based on the classification of the species Linumu sitatissimum L. On the basis of a molecular estimation the gene pool offlax it can be assumed that the fiber flax from northern continental Russia is not exclusively of Indo-afghan origin as suggested by Sinskaja (1959), but also has genetic roots in flax from Kolchidian. Essential genetic similarity between cultivar of fiber flax from Russia and other the European countries is established. Results of a generality of an origin of fiber flax cultivar from Russia are confirmed also with the analysis of their genealogy. Essential genetic polymorphism of linseed flax is shown. The distinctness of linseed and fiber flax in their genetic constitution as revealed by the RAPD analysis is of strategic importance in preservation of the genetic diversity and for efficient use of the flax gene pool in breeding. 相似文献

To achieve bio-scouring or biological degumming of the flax roving, a kind of eco-friendly techniques, an alkalophilic strain was screened from the rotten wrack around Zhoushan archipelago sea area. It was characterized as Cellulomonas sp and named Cellulomonas sp DA8 by measuring the strain morphology, physiology, biochemistry, and the 16s rDNA sequences. Determination of enzyme activity showed that the activities of petinase and xylanase were obtained, and enzyme activities are stable under 50°C and at pH values in the range of 6.5 to 9.0. It was utilized to scour the flax roving under alkaline conditions, and the result showed that the strain had a good characteristic of scouring, and less strength loss of flax fiber was 14.19%. Scanning electron microscopy (SEM) showed that the gum in the flax fiber was mostly degraded, and the most smooth fiber surface was displayed, compared with fiber untreated and scoured by caustic soda. 相似文献
