Research And Product Development On Digital Design For Traditional Wefts-backed Structure Jacquard Fabric

Based on systematic research on traditional multi-wefts backed structure jacquard fabric, this paper presents the principle and method of digital design for multi-wefts jacquard fabric, which improves the design for multi-wefts structure jacquard fabric based on digital technology.This article focus on the digital improvement design for traditional triple-wefts-structure jacquard fabric, and gives a relatively comprehensive research mainly in the following aspects with the conclusion of testing for the design examples, as well as the benefit of the product improvement in the future.First, the feature and design method of traditional multi-wefts structure jacquard fabric were analyzed. The limitation of color performance and low design efficiency are determined by traditional design method and weaving technology which is the basic reason to carry on improvement design for traditional jacquard fabric.Second, the design improvement principle and method of digital jacquard were introduced and analyzed. The design based on digital technology can break the limitation of structure and colors expression which is the theoretical basis to propose the principle of digital design applied to multi-weft-structure jacquard fabric.Third, the improved design idea of layers design and compound application for multi-wefts-backed structure jacquard fabric is proposed. Design color layers for superficial layer by adopting the colorless digital jacquard principle, establish weave data, choose superficial weaves corresponding to colors expression, and choose weaves as middle and inner layers when the balance demands of weave interlacing are satisfied. Number and arrange weaves so as to form three-wefts-backed weave data. This is the key technology of multi-wefts-backed structure jacquard favric via the deployment of digital technology.Fourth, the designed brocade for the design improvement principle and method is shown as the example of traditional three-wefts-backed structure jacquard fabric brocade. The resultant improved brocade features dual nature of merging traditional brocade and digital design technology. Further more, the ability of color performance and efficiency of product design is improved in a large extent.This study indicates that the design principle and method based on digital technology overcome the structure and colors constraints of traditional wefts-backed structure jacquard fabric. On the basis of the full covering wefts-backed structure, the shadow effect in each weft is realized. This method not only improves the design efficiency but also has promising application future for it can be applied in the design of home textile, costume textile with no constraints. It is envisaged that this study provided a good reference for the technical innovation and enhancement of product added value on Chinese traditional jacquard fabrics.
