Abstract: Abstract: This paper describes the characteristics of regular multiple weft angle interlocking fabric, and shows that there is a certain relationship between repetition of weave, step number and layers, and that its fabric structure is regular and can be used for technical purposes in the textile industry. According to the characteristics, this paper puts forward the basic operation of Excel spreadsheet that can be used to replace traditional hand-drawn graphics as a method of Regular multiple weft Angle interlocking fabric texture design. Namely, structural diagrams are first drawn in Excel, and then organizational diagrams are drawn according to the regularity between them. It has been proved that the new way of designing operation can reduce the workload and simplify the practice, making it fast and accurate, and it also lays the foundation for the development of the fabric texture CAD system.

Key words: 3-dimensional woven fabric, multi-weft angle-interlock fabric, fabrec structure, weave designing
