Twill vs Canvas Fabric

What is the difference between twill and canvas fabric?

what is the difference between twill and canvas

The main difference between these two fabrics is the weave construction.  Canvas is made with a simple plainweave pattern of “over one, under one”. Double filled canvas uses two yarns in the over under instead of one, but it is still a plainweave.

Twill farics are made by going over one yarn and under two yarns or even under three yarns.  The weave is shifted over in each row creating a diagonal line in the pattern.  The diagonal line makes a twill easy to identify.

The diagonal line also makes twills harder to tear than canvas.  Have you ever done the easy hand tearing of canvas right down the middle? It makes a nice clean tear.  Just try and do a nice clean tear on a twill.  It doesn’t work to good.  The diagonal weave makes a clean tear pretty impossible.

Our lightweight 8oz Poly Cotton twill is going to be stronger than our 7oz cotton duck.  If you are looking for a really strong, but also lightweight material a twill could be better than a canvas if tearing is a concern in the application.

The Bull Denims we carry also are classified as twills.  They are also constructed with the twill weave.  Fabrics that are woven with the twill construction that are heavyweight, commonly 12oz or more, are often called Bull Denims to set them apart from a standard twill.

Twills are more frequently used in apparel than cotton canvas.  Most people are familiar with seeing the diagonal weave line in their pants and blue jeans.  The applications of twills in apparel are commonly seen in pants, skirts, jackets, uniforms and vests. Bull Denims and cotton canvas are used for more rugged type work apparel.

Both materials have endless uses in home decor applications.  Let us know if you would like to get some samples to check out the differences for yourself.


Twill Weave : What is the Difference Between Denim & Bull Denim?

When I hear the term twill weave I automatically hear in my head “over one under two, over one under two.”  Of course it doesn’t have to be under two, it could be three or more, but this basic pattern is what makes it a twill. It is all about that diagonal line.  Unless you are wearing yoga pants you are probably wearing a twill right now. Along with plainweave it one of the most common basic weave types used in textiles.

Two very common twill fabrics are Bull Denim and Regular Denim.  Have you ever wondered what makes these fabrics different or why your blue jeans are white on the back?


Both Denim and Bull Denim are produced in a wide range of weights. Our Made in the USA Bull Denim comes in 12oz Natural and Preshrunk White.  The twill diagonal weave is durable and drapes great making it ideal for home decor applications such as slipcovers and draperies.

Measuring Textiles : What is Denier?


Do not feel bad if you are unsure what denier actually means.  During four plus years of school studying textile design I never heard the word uttered once.  It wasn’t until I had my degree in textiles that I realized how much I didn’t know.

So obviously, the bigger the number the stronger the fabric, but why is that?

Denier is a unit of measure for linear mass density of fibers.  A unit of measurement just for my favorite thing…TEXTILES!  How did they not teach us this in school?  A single strand of silk measures 1 denier. The measurement is defined as the mass of 9000 meters of fiber.  So, denier indicates fiber thickness and also weight in grams.

1 Denier =1 gram per 9000 meters

Our 600 Denier Polyester9000 meters (9842.52 yards) strand of the yarn unwoven weighs 600 grams (21.1644 oz.)

Our 1000 Denier Polyester9000 meters (9842.52 yards) strand of the yarn unwoven weighs 1000 grams (35.274 oz.)

The Denier count is important for manufacturers to make sure their materials are durable enough for the product they are producing.   Originally denier was used to measure natural fibers like cotton and silk, but now it is mostly commonly associated with synthetics like polyester and nylon.
