Material Matters is a new series we are diving into that provides a quick overview of different materials we find in our clothes, where they come from, their uses, and some quick facts that provide a general understanding of their properties. In this article we will be going over the industry go-to fabric:

A Brief Description

Cotton is the most commonly used material in the clothing industry. Cotton is to clothing as the wooden 2x4 is to construction, sure there are other synthetic and sturdier options, but it is far and wide the frontrunner in terms of common use.

Cotton fabric and the yarn it is comprised of is made from the seed fibers of the cotton plant. This is something we all learned about in history class due to the significance of the cotton gin and its influence on the United States’ economic status in the 1700s. Cotton is naturally white in color and is divided into different categories of quality based on the length of the fibers the yarns are made with. This measurement is called the Staple Length. There are generally 3 categories of Staple length:

  • Short Staple Length: ¾ inch strands- Tend to make a softer yarn, but will pill easier.

  • Medium Staple Length: ¾ inch to 1.25-inch strands- Most commonly used, and most abundant producing a sturdy and durable yarn.

  • Long Staple Length: 1.5-2.5 inch strands- More durable than the medium staple length, producing longer lasting and tougher clothes that are still soft and breathable.

In addition to various Staple length, there are over 64 common weaves patterns leading to 64 different textures and thicknesses. Common weave Patterns include:

Corduroy, Canvas, Velvet, Chambray, Pique, Denim, Twill, French Terry, Gauze, Fleece, Flannel, Jersey, Moleskin, seersucker, oxford, Poplin, Velour, Waffle Weave, and Lace

Cotton is an interesting material because its use can vary greatly based on its staple length, weave, and finishing treatment. It can be rough, soft, strong, weak, thin, thick, warm, cool, rigid, relaxed, but it will always be breathable, wrinkle fairly easily, super absorbent (as it can hold up to 27x its own weight in water), and shrinks when exposed to high heat. So how do you pick out a well-made cotton product? Because many tags won’t tell you what staple length yarn was used, brands have come up with names to differentiate superior cotton from the rest.

Common Types of High-Quality Cotton:

  • Pima Cotton: Named after the Pima American Indian tribe, Pima cotton is mostly grown in the US, it has an extra long staple length and is used to create stronger yarn leading to more durable, longer-lasting clothing.
  • Supima cotton: Simply the longest Pima cotton fibers spun into yarn, leading to even more durability.
  • Sea Island Cotton: Grown in the Carolinas, Georgia, and the West Indies Sea Island cotton is grown in a premier growing climate and cultivated in a more natural growing process resulting in a higher quality product. Sea Island Cotton is the creme of the crop when it comes to cotton and can feel more like cashmere.
  • Egyptian Cotton: Simply means it is the longest staple length cotton in a batch, not necessarily that it is from Egypt.

A note on Cotton blends:

Cotton is very often blended with other materials, most commonly with synthetics like Polyester, Spandex (elastane), and Rayon. These blends, most specifically ones with polyester (a synthetic), make the garments cheaper to produce and provide longevity to cotton fabrics. However, while polyester lasts longer, it does not naturally breathe like cotton does, so if you see a short sleeve button down that is 80% polyester, and 20% cotton, it will not be as cool as you may think. On the other hand, the addition of spandex (usually around 2%) provides wrinkles resistance, stretch, and helps garments retain shape over time without inhibiting the fabric’s ability to breathe.

Common Uses:

Pretty much everything. Apparel (like shirts, canvas shoes, shorts, pants, hats, coats, suits, etc.), painting (canvas), currency, furniture, and more.

Care Tips:

Wash less if possible, air dry the light stuff, use white vinegar on the more delicate cotton pieces, separate loads by type, weight, and color to avoid color and garment deterioration.

Avoid shrinking by removing articles from your dryer while they are still damp.

Do Guys Still Need to Pay for the First Date?

Do Guys Still Need to Pay for the First Date?

When you look at it honestly, you can’t deny that having sex has a cost. That cost, coming in the form of time, energy (both emotional and physical), and money spent has changed over the last 80 years from the conservative norms of our grandparents, to the free love movement, to the current emergence of the casual hook-up culture and shrinking of the gender wage gap. So now the question is how much does sex cost, and who should be paying the price? And while the reason has changed, the answer remains the same: Guys.
