Flax fibre cleaning for the SWM processing facility

将进行一个为期六个月的项目，为SWM国际开发一条亚麻纤维清洗线。该公司已经加工亚麻和使用纤维制造特殊纸制品超过60年。目前，SWM正在为其亚麻纤维产品开拓新市场，如生物复合材料和生物医学应用。为了满足这些应用的要求，SWM需要提高其纤维的纯度。这已成为该公司的优先事项，该公司采取的第一步是升级目前位于马尼托巴卡曼的永久去皮质设施。PDF的当前纤维产品具有约70%的纯度，即纤维产品含有70%的纤维和30%的碎片。目标是将产品纯度提高到90%。为了实现这一目标，PDF中的纤维清洁过程需要重新设计。拟议项目的目标是开发一条可适应现有PDF的纤维清洗线。在拟议的项目中，来自SWM的加工纤维将以其纤维和碎片的含量以及粒度分布为特征。将审查并选择实验室规模的清洁设备（例如振动筛、球磨机、粉碎机、旋转拣选机、梳理机和气流辅助设备）进行测试。将对每台机器和这些机器的组合进行测试。在测试过程中将测量所得纤维的纯度。根据测试结果和设计分析，将选择一组最佳设计参数，使纤维纯度最高，能量需求最低。这些设计参数将提交给SWM，用于其PDF。SWM的工程师将参与提案中描述的所有项目活动。因此，该设计可以容易地用于升级PDF。通过这个项目，UM将在亚麻纤维加工领域与SWM合作。该计划将在未来的大规模项目和更广泛的领域继续合作。

A six month project will be carried out to develop a flax fibre cleaning line for SWM International. The company has been processing flax and using fibre for making special paper products for more than 60 years. Currently, SWM is exploring new markets for their flax fibre products, such as biocomposite and biomedical applications. To meet the requirements of these applications, SWM needs to improve the purity of their fibre. This has become the company's priority, and the initial step taken by the company is to upgrade the current Permanent Decortication Facility (PDF), located in Carman, Manitoba. The current fibre product from the PDF has approximately 70% purity, i.e. the fibre product contains 70% fibre and 30% shive. The goal is to increase the product purity to 90%. To achieve this goal, the fibre cleaning process within the PDF needs to be redesigned. The objective of the proposed project is to develop a fibre cleaning line which can be adapted to the existing PDF. In the proposed project, the processed fibre from SWM will be characterised in their contents of fibre and shive as well as particle size distributions. Lab-scale cleaning equipment (e.g. vibratory screen shaker, ball mill, tumbler, rotary picker, carder, and airflow assistance) will be reviewed and selected for testing. Tests will be conducted on each individual machine and combinations of these machines. The resultant fibre purity will be measured during the tests. Based on test results and through design analysis, a set of optimal design parameters which gives the highest fibre purity and lowest energy requirement will be selected. Those design parameters will be proposed to SWM for their PDF. SWM's engineers will participate in all project activities as described in the proposal. Thus, the design can be readily used for upgrading the PDF. Through this project, UM will engage with SWM in the area of flax fibre processing. The plan is to continue the partnership into the future in large scale projects and in broader areas.
