BONDING OF MULTILAYER FIBERGLASS FABRIC WITHOUT STITCHING
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.

Composite and methods of making same

Described is a composite made from a woven fabric, a non-woven fabric, or a knitted face fabric and a non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric is needle punched such that fibers protrude into the non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric has a first polymer having a first melting point and a second polymer having a second melting point being higher than the first melting point. The nonwoven backing material comprises a third polymer having a third melting point and a fourth polymer having a fourth melting point being higher than the third melting point. The woven fabric, the non-woven fabric, or the knitted face fabric is further bonded to the nonwoven backing material applying heat to at least partially melt or soften the first polymer and the third polymer such that they bond together.
