Textile Technology
The complexity and breadth of textile
terminology simply couldn’t be put into a single blog post. This sequel
continues to explain some of the most popular terms you’re likely to run into
if you spend time working with fabric.
Double Rubs
Double Rubs is a term to describe a unit of
measure for the standard abrasion test used in home textiles manufacturing. This test conforms to a strict
procedure so that all results can be accurately evaluated and compared. The
test is performed with an apparatus called a Wyzenbeek Abrasion Tester, in
which 4 standard-sized swatches of fabrics are placed over an oscillating drum
with an abrasive surface. The fabrics are placed against the drum with a
standard weight to ensure the sample makes complete contact with the apparatus.
The term “double rub” comes from the fact that a single measurement is equal to
one back and forth movement of the device. Typically, heavy-duty fabrics are
anything greater than 15,000 double rubs. Most upholstery fabrics are in the range of 50,000 double rubs and most vinyls are
around 100,000 double rubs. It’s important to understand double rubs and to
correctly match them to the project.
Finish
Finish is a term used to describe any
treatment that alters either the performance or aesthetics of a fabric after
manufactured. Finishes can include chemical treatments to increase a fabric’s
flame resistance, mildew resistance, UV resistance, abrasion durability,
antimicrobial properties, etc. Crypton® Home and Revolution® are well-known examples of fabrics with a performance finish. Finishes that alter the appearance of fabric
include processes such as embossing or calendaring, which involve passing a
fabric through weighted rollers, either with a smooth heated surface or with a
raised pattern. The calendaring process increases the smoothness and luster of
fabric, while the embossing process is used to press prints and designs into
the surface of the fabric. Finishes are one of the most popular ways to add functionality
and usefulness to a fabric.
