With regard to the "key technology and industrialization of textile fabric color" project, what technical problems have been overcome by Lu Tai textile? How does its technological innovation inject magic into shirts?

Industry university research joint tackles color problem of fabrics

The key technology and industrialization of textile fabric color digitalization is completed by Lu Tai textile, Donghua University, Hong Kong Polytech University, Zhejiang University and Zhongyuan University of Technology. In 2017, the project won the first prize in science and technology of the Textile Industry Federation of China, and won the first prize of Shandong science and Technology Progress Award in 2018. The project has realized the digitalization technology of fabric color. It can carry out digitalization, image transmission and quality control management of fabric color with customers and production parks. The achievement has been industrialized, and its popularization and application will play a positive role in the transformation and upgrading of textile industry.

The success of the project is closely related to the construction of the research team of Lu Tai textile. In recent years, Lu Tai textile and Donghua University, Jiangnan University, Chinese Academy of Agricultural Sciences Biotechnology Research Institute, Huntsman and other dozens of domestic and foreign scientific research institutes, well-known universities and enterprises to work together to build a cross industry, cross regional, high-level "joint research and development" joint development system, has a team of Chinese Academy of engineering, Changjiang Scholars, "tens of millions of Talents Project" national level candidate, Taishan industry leader talents and professional doctorate, master's joint research and development team.

Referring to the conquest process of the project, Zhang Jianxiang, deputy general manager of Lu Tai textile, said that in the development and production of textile fabrics, the experience and materialized phenomena of color expression are common, and the accuracy and consistency of quantitative expression can not be broken through. For Lu Tai, who is committed to yarn dyed fabrics, the color problem is particularly prominent. Lu Tai's systematic research on color began in 1996. After a long period of exploration and practice, he established his own standard color system. In addition, continuous research has been carried out in the aspects of color matching accuracy, rapid simulation of fabric development pattern color, and how to achieve digital transmission and reproduction of colors.

Zhang Jianxiang said, "the key technology and industrialization of textile fabric color digitization" project is to introduce color digitalization technology into the fabric color design and production process. Aiming at the precise collocation of textile fabrics, the fine reproduction of fabric texture, the fabric imaging and intelligent inspection, the construction of digital cloud platform, the trans regional online transmission and so on, the research and integration innovation will bring the fabric research and development, production and management level to a new development track.

The scientific research team of the project has studied the precise color measurement technology of fabrics, proposed the accurate color measuring system of the color measuring system, developed the high-precision multispectral imaging color measuring equipment, broke the limitation of the sample number in the color measurement, realized the accurate color measurement of the micro samples, constructed an intelligent, efficient and accurate color matching system, established a high coverage color matching color gamut database, and developed a full information database of colored yarns and fabrics, and realized the intelligent retrieval matching and accurate color matching function of the color formula of the fabrics.

In addition, the project has made breakthroughs in the simulation technology of fabric color and texture comprehensive appearance effect, and realized the fine simulation effect of fabric on screen and paper card. Through the research of fabric image acquisition technology, the scientific research team has developed an image acquisition system which is highly consistent with the image color effect and texture characteristics. The matching algorithm of feature matrix library between color fabrics has been invented, which can realize intelligent retrieval of fabric images. A digital textile fabric cloud platform has been constructed to realize the highly integration of all kinds of information database, fabric image library, color matching function, simulation function and color pattern Internet transmission function.

Technology innovation brings magic to shirts

Project research and technological breakthroughs are ultimately aimed at producing better quality products. As the world's largest manufacturer of high-grade yarn dyed fabrics and the world's first line brand shirt manufacturer, Lu Tai textile has not only studied the fabric color for many years, but also has many innovative technologies, such as nano three protection, easy decontamination, ironing, wrinkle resistance and so on, which also creates magic shirts for consumers.

From the perspective of consumers, product innovation is the concept that Lu Tai textile has always followed. For example, energy saving and environmental protection multi-functional shirt, the shirt has different functions of ironing, waterproof, oil proof, antifouling, easy decontamination, moisture absorption and breathability. The collar and cuffs are easy to stain, and difficult to wash, using liquid ammonia crosslinking + three anti decontamination fabrics; the front piece is easy to smear oil and stain when eating, using liquid ammonia crosslinking + nano three anti + Fresh finishing fabric; the back and sleeves are easy to fold and sweat, and adopt liquid ammonia crosslinking and non iron + fast drying pure cotton fabric. The technology of self decontamination functional fabric combination developed by Lu Tai textile has environmental protection functions such as reducing clothing handling times, prolonging the use time of clothing, reducing detergent consumption and washing water consumption.

For the wrinkle problem of shirts that consumers always criticised, the rutile textile's easy decontamination and ironing shirts directly hit the pain spot. Through modifying the surface of pure cotton yarn, the positive and negative sides of the fabric have wrinkle resistance. The pollution-free physical treatment method makes the pure cotton fabric warp and weft to the natural bomb and enhances the hydrophilicity of the yarn at the same time. According to the liquid ammonia finishing technology, a new tidal cross-linking finishing technology for energy saving and emission reduction is developed to improve the fabric's ironing performance at low temperature. The formaldehyde free, easy to iron and easy decontamination finishing technology developed by Lu Tai has the characteristics of low baking temperature, and the fabric has the properties of ironing, formaldehyde free and easy decontamination.

With the increasing environmental protection of consumers, the eco friendly shirts on the market are also increasing. The Eco Mist eco friendly shirt of Lu Tai textile has made cationic modification of cotton fibers, and developed a continuous salt free and alkali free dyeing technology and equipment for cellulosic fibers. It has solved the problem of continuous dyeing with low bath ratio, realized continuous fiber salt free and alkali free dyeing, developed a precise acquisition and intelligent retrieval system for fabrics using color digital transmission technology, and constructed an efficient fabric digital R & D and management cloud platform, forming a color digitalization function system widely applied in the fields of color spinning, dyed weaving and dyeing and printing. It solved the problem of color consistency and accuracy of textile fabrics, and greatly shortened the development cycle of colored fabrics. In terms of technological innovation research, the salt free alkali free dyeing process has been created, and innovative dyes and auxiliaries for dyeing, dyeing and dyeing of fibers, yarns and fabrics have been developed.

Transformation and upgrading is always on the road. As a single champion of manufacturing industry, Lu Tai textile hopes to make technology transformation, upgrade the textile industry and develop into a manufacturing service oriented enterprise, and become an innovative international enterprise with standard setting and technology export.
