The conventional way to manufacture seamless 3-D textiles is by non-woven technology. But lack of cellular structure in non-woven materials makes it impossible to obtain properties inherent to woven fabrics. This fact limits the spectrum of seamless shells range.
Therefore to meet all the requirements of 3-dimensional seamless products for apparel and industrial use, it is advantageous to employ seamless 3-axial shells. The Moscow State University of Design and Technology has come up with a new method of 3-D shells design.
Woven seamless shells consist of three types of basic threads: initial, right and left wefts, and also of the supplementary molding threads. Novelty of the method is in getting the supplementary threads in two directions at the same time by using the thread with breakpoint. This gives the determined three-dimensional form to the shell and stability to the fabric structure.
This method of making shells removes defects, which previous methods of shells production used to carry by replacing warp threads by right and left wefts. This allows getting the supplementary thread in the fabric structure with breakpoint so that it crosses each initial thread twice. In this case the algorithm of interlacing will be stable and the set changes of shell curvature will be provided exactly.
Design methods for 3-D one-piece woven or braided textiles prove to be highly effective especially in manufacture of special-purpose woven goods, where the excessive seams have a negative effect on the apparels.
