In recent years, Ningbo's garment industry has taken digital transformation as one of the key elements to enhance its core competitiveness, continuously explored the digital transformation of the industry, and promoted the innovation and development of the industry.
To this end, Zhejiang Textile Service Institute cooperates with regional "specialized, sophisticated" enterprises to jointly explore and practice the learning factory of enterprise digital technological transformation and professional digital teaching: focus on the pain points and difficulties of digital "intelligent manufacturing" transformation and upgrading of small and medium-sized enterprises, and build an open, continuously upgraded and iterative garment intelligent manufacturing demonstration line;
School-enterprise cooperation "two-way running"
For the traditional textile and garment industry, with the rapid growth of demand for flexible and customized production, the demand for cost reduction and efficiency increase is becoming increasingly urgent, and digital empowerment has become an effective starting point.
"When there are more orders, types and styles from customers, it is no longer possible to complete production efficiently by traditional manual methods. The relevant person in charge of Ningbo Jiana Garment Co., Ltd. told reporters that the company mainly focuses on the production and processing of high-quality clothing, mainly for foreign trade orders, and urgently needs to improve the flexible and quick reaction ability and production and operation efficiency.
Zhejiang Textile Service Institute clothing intelligent digital factory has created a demonstration line composed of multiple units from front-end garment 3D design, raw material warehouse, automatic cloth spreading, automatic cutting bed, intelligent suspension, air warehousing and automatic unmanned rear road and automatic logistics transportation, focusing on the typical technical application of intelligent digital transformation of the garment manufacturing industry, as well as the new technology, new process and new trend that can be upgraded, and has a demonstration role and "pilot" role in the digital technological transformation of traditional small and medium-sized enterprises in Ningbo.

In addition, on the basis of the comprehensive digitization of production factors and the cloud deployment of cloud aggregation and management operation systems, an end-to-end production command brain system is built, which realizes the cloud generation and automatic issuance of decision-making instructions and data flow in the production process, and explores a new model of end-to-end automatic data flow.
After solving the problems of "imperfect data collection in the production process", "difficult to control the production process", "chaotic equipment management" and "lack of visual scenes", the digital factory of Jiana Apparel began to operate.
Nowadays, in the digital factory of Jiana Apparel, orders can be changed and inserted at any time, and the execution effect is increased by 60%; each order is saved immediately, and the order damage and loss rate is reduced by 100%; semi-automatic scheduling is realized, the personnel scheduling time is reduced by more than 80%, and the scheduling accuracy can reach more than 90%; the workshop output is counted in real time, and the piecework accuracy is increased by 98% by scanning code and piecework data collection......
"Our employees have changed from operators who do repetitive and tedious tasks to technicians who study and control machines and equipment. The relevant person in charge of Ningbo Jiana Garment Co., Ltd. said, "After the operation of the digital factory, the display screen in the workshop can display the production volume of workers in real time, especially for scheduling, its advantages are very obvious." ”

It is worth mentioning that the school also provides differentiated intelligent transformation needs and staff training for small and medium-sized garment enterprises through the combination of school-enterprise full-time and cross-professional technical service team formation in the school. At present, it has served more than 1,000 small and medium-sized enterprises in digital technology transformation, served more than 1,200 students in internship practice every year, and was selected as the internship training base for the integration of industry and education in vocational colleges in Zhejiang Province.
"Next, we will rely on the provincial industrial brain to serve the digital transformation of small and medium-sized enterprises in Zhejiang Province, and radiate more small and medium-sized enterprises from point to area. Wang Weiwei, deputy dean of the School of Fashion of Zhejiang Textile and Garment Vocational and Technical College, said.
"Digital Twin" integration of industry and education
Digital empowerment has realized the school's professional training and teaching reform of "combining virtual and real and digital twins".
"We have formulated five training standards in the fields of digital design, intelligent manufacturing, and display. After consolidating the basic knowledge and basic training, students first practice in real jobs, and then use digital twin technology to learn virtual design and intelligent production courses. Wang Weiwei told reporters.
In the school's virtual simulation training room, students can select fabrics, adjust prints and other operations on the computer, simulate the effect of clothing design, check the shape and fit of clothing, and modify the design in real time.

In the smart digital factory of clothing, the school continues to introduce new technologies and new equipment to promote the digital and intelligent upgrading of the clothing profession - 3D virtual design technology and real production of intelligent equipment are connected together, and students can experience the whole chain from virtual design to real production.
In the school-enterprise cooperation training position, students can receive real job training during the winter and summer vacations, combine the training with the simulated production scene in the school, be problem-oriented in the training, dig out knowledge and technology from the professional basic courses and professional core courses, learn the important and difficult points of the course, and improve the ability to innovate and solve problems for the job.
Through 4-5 frequency rotation training, the combination of virtual and real interaction is connected, digital technology has always grown together, and students' ability to innovate and apply digital technology has been significantly improved.
"From fabric selection, pattern development to process production, I am deeply involved in all aspects of garment manufacturing, and I have a deeper understanding of modern garment manufacturing in practice. Thanks to my professional studies in school, I was able to quickly adapt to the development rhythm of the enterprise, not only learned how to apply theoretical knowledge to practical operation, but also understood the requirements of the enterprise for skilled talents. I believe that these valuable experiences will provide me with strong support for my future career development. Li Hongxi, a 21-level student majoring in fashion design and technology, told reporters that with the platform built by the school, he conducted internships in well-known clothing companies such as Kaixin and Youngor, and participated in real projects of enterprises, and these practical experiences laid a solid foundation for future career development.
