FABRIC FACTS
Coating on furniture fabric gives the fabric several advantages. (1) The coating
prevents the smooth yarns from slipping and unraveling. (2) The coating gives the
fabric additional body and stiffness. The coating is usually rubber or latex. The
cleaner usually only receives the pillow covers as they are the only removable part.
The fact that the cover has a zipper does not mean that the manufacturer intends
that it should be removed. The zipper is for the use of the manufacturer in
obtaining a tight fit. Coated covers can be made of any fiber. Those fabrics woven
with olefin or polypropylene yarns may be sold under the trade names of Herculon,
Durel, Marvess and Vectra.
FABRIC PROBLEMS
The fabric coating may dissolve in drycleaning or peel and crack from mechanical
action in drycleaning or in normal use and wear. When the coating is totally or
partially lost, the fabric shreds because the loose weave with large size yarns are
no longer held in place. The shredding occurs when the yarns slip past the seam
edges where the pillow covers have shallow seam allowances and unfinished or
bound seam edges. Once the fabric starts to shred, it cannot be corrected. The
entire fabric will eventually shred. Loss of body takes place as the fabric coating is
removed through normal use or in the drycleaning process. Shrinkage will result
because olefin is extremely heat-sensitive. Shrinkage may also result if the fabric
coating which was used on the fabric stretched in manufacturing, or if the fabric
was not pre-shrunk. As the coating is lost, relaxation shrinkage occurs.
INSPECTION
Turn pillow covers inside out and inspect the reverse side of the fabric. Look for
peeling and cracking. Feel the fabric to determine whether it is stiff, rubbery or
gummy. Even though these conditions have not occurred, it is wise to test the
fabric by rubbing an unexposed seam with cheesecloth saturated with amyl
acetate. Look for peeling and feel for tackiness. Obtain a customer's written release
against shrinkage since even a 2% shrinkage factor may render the furniture cover
unusable. Also obtain a written release if the pillow covers are badly soiled, stained
or faded. The condition may not be improved. Olefin fiber is the most heat
sensitive of all the man made fibers. To test for heat sensitivity, remove a yarn
from a seam and hold a match to it. Olefin will shrink away from the flame.
DRYCLEANING
This process is hazardous to most coated fabrics. A customer release must be
obtained. Dryclean for only 1 minute in a high solvent level. Use no moisture to
minimize the loss of coating and to reduce the possibility of shredding and fabric
shrinkage. It is safer to limit the tumbling and allow to dry with air circulation only.
Surface cleaning is safer but not thorough. Use a shampoo lather on the surface
and remove with a damp cloth.
PRESPOTTING
Because of the recommended short drycleaning cycle, loosen and remove
imbedded soil before drycleaning by prespotting. Use wetside prespotters. Dryside
lubricants will adversely affect the coating. Use limited mechanical action and
tamping to prevent peeling and cracking of coating.
SPOTTING
Hold the steam gun at least eight inches from the fabric surface to avoid yarn
separation and possible damage from the heat. Use a neutral lubricant and tamp or
brush very lightly. Avoid using dryside lubricants and solvent.
WETCLEANING
Wetcleaning may be safer to the coating but may produce shrinkage, especially on
cottons, linens and rayons. Hand wash pillow covers because machine washing
may cause shrinkage, shredding and peeling. Soak in cool water at about 90° F
with a mild lubricant. Brush lightly, rinse thoroughly, extract and hang to dry.
FINISHING
Do not use steam or heat when finishing pillow covers made with olefin fiber.
Shrinkage and puckering may result. When touch-up finishing is required, use a
cool iron. Other fibers may be steamed and stretched.
SUMMARY
Coated furniture fabrics are usually unserviceable. The coating substance seldom
will withstand the mechanical action in normal use or in the drycleaning
procedures. The coating substance is usually soluble in drycleaning solvent. When
the coating is partially or totally lost, shredding will result, especially in loose
weaves of heavy yarns. These heavy yarns may appear rugged and sturdy. Olefin
is heat-sensitive and will shrink or pucker from the heat of the reclaimer, dryer or
finishing equipment. The wetcleaning process may be safer to the coating but can
result in shrinkage of the fabric. Manufacturers of furniture fabrics often disclaim
responsibility for problems if covers are removed for cleaning. Obtain a written
release before accepting coated pillow covers. |
