A serged seam joins two pieces of material with a thread stitch that
interlocks. This is an economical stitching method for general applications. This
stitching method is generally not used for chemical protective clothing. It is more
commonly found on limited use clothing where dry particulates are of a concern.
|Sewn and Bound
This seam joins two pieces of material
with an overlay of similar material and is chain stitched through all of the layers for a
clean finished edge. This provides increased holdout of liquids and dry particulates.
|Heat Sealed Seam|
A heat sealed seam is sewn and then sealed with a heat activated tape.
This method provides liquid proof seams, and is especially
useful for Level A and B
chemical protective clothing.
