Cotton Facts and Information

Comfortable – no surface characteristics irritating to the skin

Natural affinity for water - it attracts moisture from your body

Moisture passes freely through cotton aiding in evaporation and cooling

Good Heat Conductivity – allows heat to dissipate - good for bedding products

Cotton has a lack of resiliency; a fabric made with all cotton fibers tends to wrinkle

Cotton is strong and abrasion resistant

Polyester – Facts and Information

Polyester is a man-made fiber that can be produced in many different formats including staples (not unlike cotton) and monofilament strands

Polyester has good strength and abrasion resistance but does tend to pill

Polyester has excellent resiliency; it is wrinkle resistant

Polyester is hydrophobic; it will not absorb water

Because it does not absorb moisture it is not as good as cotton for bedding fabrics for retail but the above features make it ideal for Hospitality

Cotton/Polyester Blends

Cotton/Polyester Blends are common in the sheet industry and in Hospitality

Polyester resists shrinkage and wrinkling while cotton provides a good feel and breath-ability

Traditionally polyester was lower in cost than cotton – not necessarily true in today's world

Weaving Basics– Terminology

WARP Yarns- the yarns that extend from the back of the of the loom through to the front; the yarns that run the length of the fabric. Also known as "ends"

WEFT Yarns- the yarns that are "woven" into the warp yarns across the width of the fabric. Also known as "picks"

Weaving Basics - Plain Weave

The Plain weave is the simplest of all weaves. It is referred to as a one by one weave (1x1)

One by one means that each weft yarn goes over one warp yarn then under one warp yarn, repeating this pattern across the width of the fabric

The plain weave makes the tightest weave and thus makes the best down proof fabric

The plain weave produces the lightest weight fabric for a given yarn size

The plain weave is the easiest to weave (can woven on the most basic loom)

Weaving Basics-Twill Weave

The twill weave is a very strong weave. It is commonly referred to as a two by one weave (2 x 1)

Two by one means that each weft yarn goes under two warp yarns then over one warp yarn. The next weft yarn follows the

same pattern but offset by one warp yarn

By moving the yarn in which the weft yarn goes over the warp yarn with each cycle of the loom, the exposed weft yarns set up a diagonal line across the fabric known as a TWILL LINE

DENIM is the classic twill weave



Have more threads per square inch then plain weaves with the same yarn size

Weaving Basics - Sateen Weave

The SATEEN weave is the most complex of the basic weaves; it is referred to as a four by one (4 x 1) weave

Four by one means that each weft yarn goes under four warp yarns then over the fifth warp yarn

A sateen weave does not have twill lines as the twill lines are broken up in the repeat of the weave

Very even surface

Softer feel

More yarns per square inch with the same yarn size than either plain weave or twill weave

Thread Count

Thread count given to the United States are generally given using inches as the unit of measurement (threads per inch)

The threads per inch are counted across the warp and then added to the threads per inch in the weft it gives the "threads per square inch" that is used in product marketing

Note: With regards to thread count, counts are always given for GREIGE fabric. Greige fabric is the unbleached, undyed

fabric that comes off the loom. In the finishing process, the fabric usually shrinks which increases the actual finished thread count from the stated greige count

Finishing – Sanforizing

Sanforizing is a trade name for a mechanical pre-shrinking process. In the Sanforizing process the fabric is allowed to relax to the full extent possible

Sanforizing is a permanent way to minimize residual shrinkage

The cost of Sanforizing is not in the process, but rather in the loss of cloth during the process. The length of the cloth will easily shrink 6% to 8% in the process

PCF Barrier Weave Fabrics

Barrier Weave is a proprietary finishing process applied to all Pacific Coast® brand products' fabric

Barrier Weave results in a tighter weave which means less down and/or feather leakage

The end result is that Pacific Coast brand bedding is the most leak-proof in the industry
