课程介绍
近年来,我国纺织行业借助“一带一路”战略,加快了结构转型升级步伐和产业布局步伐,进行了跨区域布局甚至是跨国布局;天津工业大学纺织科学与工程学科于2017年入选国家“双一流”学科建设序列,以培养一流纺织人才为宗旨,定位于全面提升人才培养质量、科研实力水平、国际影响力和社会服务能力,建成特色鲜明、行业领先、国外有影响的世界一流纺织学科。为此,越来越多的海外留学生到我国进行纺织工程专业的长期学习或者短期交流,而我校也分别与巴基斯坦和蒙古国等合作建校,未来将有更多的教师和学生进行校际间的互访。截至目前,纺织学院已连续4届与德国下莱茵应用技术大学合作培养人才;同时,从2015年开始,第一批斯里兰卡学历生也开始在纺织学院系统学习纺织类相关知识。针对纺织工程领域国际教育学生,纱线的加工仍然是专业课程学习的基础。
依托天津工业大学纺织科学与工程一流学科、特色专业、实验教学示范中心及工程实践教育中心等优质教育资源,依据国际化人才培养的需求和授课对象,课程负责人通过整合目前国内本科生教学中“纺纱原理”、“纺纱设备现场课”“纺纱实验”等相关内容,从2014年开始开设了适合具体授课对象的新型精品课程“Spinning Technology”(“纺纱学”)。本课程以教学研究为先导,以国家级精品课、精品资源共享课和精品视频公开课等课程建设为抓手,不断创新教育教学方法,提升教师国际教育教学水平,全面提升学生的工程实践与创新能力,使学生基本具备分析问题与解决复杂工程问题的能力,为在该领域从事技术研发、生产管理、纺织品设计、商务贸易与检测和科学研究等方面的工作提供良好的有关纱线的知识背景。
“Spinning Technology” 课程每学年上、下学期各开设1次,均为学位课,其中:每学年的第一学期开设的“纺纱学”全英文课程涵盖在“Production of Textiles”的教学计划中,约16学时,其授课对象为来自德国下莱茵应用技术大学的本科生,平均4~6人/届;每学年的第二学期开设的“纺纱学”全英文课程为60学时,授课对象为纺织工程专业国际班学生和斯里兰卡学历留学生,同时也有部分来自突尼斯、法国等国家的交流生选修该门课程,平均25人/届,其中留学生占比约40%。在“Spinning Technology“教学内容中,针对国内学生开设的“纺纱原理”中的基本知识和实验实践仍然是其核心内容,每学年均在第一学期开设60学时,授课对象为大学三年级纺织工程专业所有学生,约300人/学年。该课程分别于2003年成为校级优秀课程、2004年成为市级精品课程、2010年成为国家级精品课程、2013年成为国家级精品资源共享课程。 这些教育教学成果为本课程的建设提供了良好的基础和依托。

Recently, based on the strategy of “ One Belt One Road”, the structural transformation, upgrading and layout of China’s textile industry have been accelerated, especially focusing on the cross-regional and transnational layout. In 2017, the discipline—the Textile Science & Engineering had been successfully participated in the country’s construction plan of first-class disciplines. The purpose is to cultivate first-class textile talents by completely improving quality, research capability, international influence and social service. More and more foreign students, therefore, come to Tianjin Polytechnic university for long-term learning or short-term exchange in Textile Engineering. In the meanwhile, Tianjin Polytechnic University cooperates with Pakistan and Mongolia for building universities. In the future, there will be more students and teachers attending to the exchange visits. Until now, School of Textiles have cooperated with Hochschule Niederrhein of Germany for 4 years to cultivate Bachelor degree student and Undergraduate student. In the meanwhile, the Srili Lanka students came to the School of Textiles for systematically learning textile knowledge as college students. For all of these international education students majoring in Textile Engineering, the production of spun-yarn is still the basis during the major studies.
Based on the excellent education resources from first-class discipline of Textile Science & Engineering, characteristic major, Experimental Teaching Demonstration Center and Engineering Practice Education Center, and considering the requirements on cultivation of international talents and students background, the director of this lecture set up a new “Spinning Technology” for international students in 2014 by integrating “Spinning Principle”, “Spinning Equipment Practice”, and “Spinning Experiments”. The teaching teams frequently innovate education methods and improve international education quality of teachers. The objective of this lecture is to completely improve the practice and innovation ability of the students, hoping to provide all of the students solid yarn knowledge for the future R&D, management, textile design, textile trade, and measurements. 
“Spinning Technology” is a degree class, and open in the first and second semester once in one year, respectively. Among them, there are about 16 courses in the first semester and included in the “ Production of Textiles”. The students are from Hochschule Niederrhein of Germany, and each semester there will be 4-6 students. In the second semester, the lecture is arranged 60 courses for Chinese students and Sri Lanka students. Sometimes, the students from Tunisia, Pakistan and French who are interested in spun yarn production will also attend to this lecture. Each semester there will be 25 students, and the foreign students account for 40%. The core theoretical and practical contents are derived from “Spinning Principle(in Chinese)” which is set up in the first semester for 60 courses and about 300 students. The “Spinning Principle(in Chinese)” is Excellent Course of Tianjin Polytechnic University in 2003, Excellent Course of Tianjin in 2004, Excellent Course of China in 2010, and Excellent Sharing Course of China in 2013. All of these achievements provide excellent basis for the construction of this lecture.

1.     CourseDescription

Spinningis an engineering science dealing with principles and processing of shortstaple fibers. The main task of this subject is that students will know the spinningprocess, machines used and arrangements, various spinning principles, andrelationships between principle and spinning practice in the short and longstaple spinning. Sixty courses are arranged to finish the main tasks. In thesystematic studying, firstly, the students are required to master the basictheory of opening, cleaning, blending, carding, combing, drawing, twisting andwinding. Secondly, based on the knowledge, the students should use theseprinciples to arrange spinning process for different fibers, design sometypical parameters and realize these parameters on the machines used by somecalculations. It is important to cultivate the students’ ability of designingand spinning single yarns, and the ability of analyzing and solving problemsappeared during spinning practices.
