Abstract
The leakage of water through seams has long been studied by the Army in its quest for rainproof clothing and equipage. While many researchers have reported theories of liquid migration on and through textile assemblies, this study is the first known attempt to test seams for penetration by liquid chemicals and to develop a seam type that will help to resist this penetration, important steps in the development of chemical and biological protective overgarments.
The results have shown that the behavior of liquids on seams depends not only on the chemicals but also on the cords. The conclusion is reached that effective protection against seam leakage can be provided by an LSc-1 seam with a superimposed cord having both migration and absorption properties. Such a cord might be constructed with an absorbent inner core and a braid-like outer covering made of synthetic fibers. More research on this subject is indicated.
