1928年，北京工业专门学校更名为“北平大学第一工学院”，翌年，易名为“北平大学工学院”。机织科也改称北平大学工学院机织系。北平大学工学院学制为本科四年，课程体系日趋稳定完善，提出“本院学科乃完全实用科学”，是“造就技术专门人才之最高学府”，以“培养韧作人才，完成建设事业，增高生产技艺，实现民生主义”为方针。这标志着我国纺织高等教育已开始走上自主专业学科发展的道路，对培育纺织专门人才起到了重要作用。在此期间，机织系有七位教授和两位讲师，可谓极一时之选。骨干教师从此相对稳定，系之所至，人即随之，使我国北方最早的一脉纺织系科薪火始终未泯，根系得以延续。

Beijing Polytechnic School was renamed as “The First Polytechnic School of Peking School” in 1928, and then to “Polytechnic School of Peking University” next year. The Department of Weaving was also renamed as Faculty of Weaving, Polytechnic School, Peking University. Adopting a four-year undergraduate school system, the Polytechnic School of Peking University gradually stabilized and perfected its curricular system and announced that “the school teaches a completely applied science”, is “the highest education institution for textile talents”, and follows the policy of “training the talents of polytechnic, completing the course of construction, enhancing the techniques of production, realizing the people’s better livelihood”. This signified that China’s higher education of textile started the journey of independent and specialized development and played an important role in the training of textile talents. During the period, The Faculty of Weaving had seven professors and two lecturers, which were the best teachers at that time. Later on, more and more teachers joined the faculty to continue the earliest teaching of weaving in North China.
