Troubleshooting Undesirable Finishes
Problem: Possible Causes/Corrective Action:
Wrinkles in the fabric are not removed. There is not enough moisture in the fabric. Dry fabric cannot
be ironed. See chart below for moisture retention.
The fabric is not completely dry. 1. The roll temperature is too low. Try a higher
temperature, but do not exceed the maximum
temperature tolerance of the most sensitive fiber.
2. The feed speed is too fast. Adjust the speed so the fabric
is dry after one pass.
3. The fabric moisture content is too high.
a. Provide a longer washer extraction time.
b. Provide a higher washer g-force extraction speed.
c. Partially dry (in a tumbler) the linen before
finishing.
There are lengthwise wrinkles in the fabric. The operators must stretch the fabric side to side during the
feed process.
There are crosswise wrinkles in the fabric. The return ribbon travel is uneven.
1. The return drive roll could be slipping on the ribbons.
This could be caused by the presence of fabric softener
on the roll. Fabric softener should not be used on fabrics
that will be ironed.
2. The ribbon length is uneven. Uneven length ribbons will
not drive the roll evenly.
Only a few articles can be ironed before the finish quality
deteriorates. The operators must wait a few minutes before
proceeding in order to process linen to the proper finish.
1. There is too much water in the fabric. Large articles with
excessive water content will remove a great amount of
heat from the roll or shoe. This will reduce the roll or
shoe temperature below that required to obtain an
acceptable dry and finish. In order to compensate the
operators may set the temperature too high. This may
scorch the first items and can also damage the
mechanical and electrical systems of the finisher.
2. The feeder speed is too fast. Slow down the feed speed.
There is color or staining on the finished material. The wash process has not cleaned the fabric. Impurities such
as soil, minerals, sour or detergent may still be present in the
fabric. Since only the water is removed from the fabric during
the finishing process, any impurities will remain as a deposit
on the linen or finisher surfaces.
The fabric is scorched. The roll or shoe temperature is too high. Reduce the
temperature.
NOTE: The entire width of the finisher should be used to
prevent overheating the unused surface. Small articles
should be processed in a pattern that utilizes the entire
width.
