Raincoat Damaged During Drycleaning

Q:
I drycleaned a raincoat containing polyester, polyurethane, and cotton that had a care label that instructed “Dry Clean only.” After drycleaning I saw yellow stains and streaks all over the coat. What was the cause of it? 

A: Such garments are usually made of fabrics bonded together with glue. These fabrics should have a sufficiently high peel bond strength to resist separation under normal conditions of expected wear and later cleaning for a reasonable period of time. These fabrics failed to have the necessary resistance to the proper care process. The bonded fabrics lacked resistance to accepted cleaning procedures because of insufficient time, temperature or pressure used in the original fusing process during manufacture.

The yellowing, stains or streaks were due to strike-through of the bonding agent. This is caused when the fusible adhesive of the interlining over-liquified during bonding due to tempera- tures that were too high, pressure that was too high or a fusing time that is too long. Strike-through causes the adhesive to come through the face of the fabric, and since this fabric has a polyurethane coating the adhesive would be trapped between the fabric and the coating. This explains the poor bond strength as well.

Caption: The yellow stains and streaks are attributed to strike-through of the bonding agent. The manufacturer must ensure that the bonded fabrics can withstand accepted cleaning procedures.
