Abstract
A woven fabric seam area is provided including a top surface and a bottom surface, with the woven fabric being formed of warp yarns interwoven with weft yarns in a repeating pattern, and either the warp yarns or the weft yarns are formed at least in part of a laser energy absorbent material. Within the fabric seam area yarns formed of laser energy transparent material can be bonded to yarns being formed at least in part of a laser energy absorbent material by laser welds in order to maintain or achieve a desired flexibility and/or shear resistance of the fabric. A method of forming such a fabric seam area is also provided.
Claims11
A seamed woven fabric, comprising:
- a system of warp yarns interwoven with a system of weft yarns in a repeating pattern to define a woven fabric having ends interconnected in a seam area,
- wherein the system of weft yarns includes yarns formed at least in part of a laser energy absorbent material, and
- in the seam area of the seamed woven fabric, all of the weft yarns in the system of weft yarns are formed at least in part of the laser energy absorbent material, and laser fused bonds are formed between at least some of the warp yarns that are formed of a laser transparent material and the weft yarns in the seam area that are formed at least in part of the laser energy absorbent material only at points where the warp yarns pass between applied laser energy applied to an entirety of the seam area and the weft yarns formed at least in part of the laser energy absorbent material such that the laser fused bonds are evenly distributed throughout the seam area resulting in a uniform air permeability profile for uniform airflow and a level of bond sites that strengthens the seam area and provides flexibility.
