Thread Count & GSM

by Sierra Neale

Thread Count
Often, you may see thread count or TC mentioned in product listings. The TC stands for thread count. Thread count refers to the number of yarns in a square inch of a woven fabric.

Woven fabrics are made up of two sets of yarns interlacing with each other. The two sets of yarns are known as the warp and the weft. The warp is the set of yarns that run vertically along the loom and the weft are the yarns that run horizontally. The thread count of a fabric is calculated by using both the EPI (ends per inch) and PPI (picks per inch). The EPI refers to the warp yarns per inch and the PPI refers to the weft.

There is the common misconception that a higher thread count equals a higher quality or better fabric. This is not always the case as the quality of the fibers and yarn, the type of weave, the dyeing process, finishes and etc. all factor into the final hand feel and quality of the fabric. 

Also, sometimes to achieve a higher thread count lower quality yarn is used which can lead to less durable sheets. Which is why although we offer a variety of thread count sheets we never compromise when it comes to quality. Thread count can affect the weight of the fabric, which is why we offer various thread counts to meet everyone’s needs and preferences.  

One of our new arrivals, the Brielle Home 300 Thread Count TENCEL™ Lyocell Sateen Sheets is available in five colors. The combination of its 300 thread count, sateen weave construction and TENCEL™ Lyocell fiber content make this sheet unbelievably silky soft and perfect for year round use.

Brielle Home 300 Thread Count 100% Viscose from Bamboo Sateen Sheet Set is made with 100% viscose from bamboo fiber, has a soft hand and is perfect weight for use year round.

 Our  Brielle Home 300 Thread Count 100% Cotton Sateen Sheet Set and Brielle Home 400 Thread Count 100% Cotton Sateen Sheet Set are both OEKO-TEX® certified and have smooth hand feels that gets softer after each wash similar to our premium  Brielle Home 600 Thread Count 100% Cotton Sateen Sheets.

Microfiber fabrics do not use thread count to identify the quality or density of the fabric but use GSM (grams per square meter) to refer to the weight of the fabric.

We have two unbelievably soft microfiber sheet set programs Cosmic Comfort™ Birthstone Sheet Sets and Brielle Home Extra Soft Sheets Sets. Both are made out of 100 GSM brushed polyester microfiber. The brushing of the fabric gives the sheets their ultra silky soft hand-feel. Unlike the usual thin and scratchy microfiber sheets in the market, our sheets are made out of a heavier weight fabric and brushed for added softness. They are the ultimate no-fuss, easy care sheets as they are machine washable and naturally resistant to shrinking, fading and wrinkles.

Unlike woven fabrics, knitted fabrics are not made out two sets of yarns but one continuous length interlooping with itself. Needles are used to do the interlooping whether knits are done by hand or machine. A loop/stitch refers to the smallest part of a knitted fabric which are the individual loops/stitches the needles are creating. Gauge refers to the number of needles in an inch, the higher the gauge number the finer the knit. Which is why for knitted fabrics we refer to gauge or GSM (grams per square meter) and not thread count.
