I just took
a blue silk blouse out of the cleaning machine and where the perspiration has
discolored the underarms,
holes have appeared. This has happened before and the customers always think it
is my fault. Can you explain this type of damage?
chemical testing over the years of many, many similar situations almost always
reveals the presence of chloride salts in the damaged areas. Textile research
has shown that chloride salts of any type will weaken silk yarns over a period
salts are present in many foods, beverages, medicines, table salt, and salt
water, as well as perspiration and some deodorants. The location of your
damaged area definitely indicates that perspiration and/or deodorant have
deteriorated the silk yarns to the point that the agitation of cleaning caused
the weakened yarns to tear. Unfortunately, there is no practical way to predict
or prevent this type of damage from occurring during acceptable cleaning.
