20230116210 · 2023-04-13 ·

Multilayer fibreglass fabric with stitching comprises various stitching processes. These stitching processes not only create poor-surface finish but also it reduces the mechanical strength and increases cost of process and machinery. Therefore, present disclosure proposes a method for bonding of multilayer fiberglass fabric without stitching which comprises: pre-processing (601) wherein a raw material is selected and assembled according to requirement or final product. Processing (602) wherein processes like pressure rolling and needle punching are carried out. Post-processing (603) wherein the output in winded up, cut and packed in pre-determined sizes and dispatched. In present disclosure various combinations of input material are possible according to customer requirements.
