Your t-shirt will have no more secrets for you

Ton t-shirt n'aura plus de secret pour toi

T-shirts are very attractive, durable and versatile garments that can be worn as outerwear or undergarments. You certainly wear them for your yoga sessions.

Since their inception in 1920, T-shirts have evolved into a multi-billion dollar market.

T-shirts come in a variety of colors, patterns, and styles, such as the standard crew neck and v-neck, as well as tank tops and scoop necks.

T-shirt sleeves can be short or long, capped, yoke or raglan. Additional features include pockets and decorative trim.

T-shirts are also popular garments on which to display one's interests, tastes, and way of thinking using custom screen prints or heat transfers.

In this article, we looked at cotton t-shirts. We will reveal their secrets to you.

The next time you put on your t-shirt before your yoga session, you'll know all about this must-have garment.

The raw materials used for the manufacture of t-shirts

Most T-shirts are 100% cotton, polyester, or a cotton/polyester blend. Environmentally conscious manufacturers can use cotton from organic farming and natural dyes (such as yofe for example...).

Stretch t-shirts are made of knit fabrics, specifically jerseys, rib knits and interlock rib knits, which consist of two rib fabrics that are joined together.

Cotton spinning, a step that is very important in the quality of your t-shirt

There are several ways to spin the yarn, but the most common spinning ways when it comes to cotton for T-shirt making are open-end spinning, ring spinning, or compact spinning.

Open End Spinning

Open-end spinning, also known as snap spinning or rotor spinning, is a technology that was created to allow yarn to be created without the use of a spindle.

The sliver from the carding process enters the rotor where the action of the rotor twists to spin the sliver into yarn which is continuously pulled out of the chamber and wound into a spool.

Open-end spinning is limited to the production of thicker or coarser yarns. The yarns are more hairy, and the fabric will be more likely to pill, so this is not a good method for making quality textiles.

Ring spinning

It is the oldest system and based on original spinning methods. Ring spinning is a continuous process in which fibers are twisted and shrunk to create a fine rope of cotton fibers. The more the fiber is twisted, the softer the fabric will be.

It operates using a pressed steel ring frame. The spindles are placed on either side of the frame, while the draw rollers are placed above them with a creel loaded with coils of what is called roving (an unspun thread).

Ring spinning is not used in production as much as open-end systems, but it still produces yarn that is of higher quality.

The yarns are finer and smoother, more durable and much less hairy than an open ended yarn. However, due to the additional steps that go into roving and winding the yarn and the slower rate of production, it results in it being much more expensive to produce the yarn by this method.

Compact Spinning

Compact spinning is a modern method of condensing the fibers together by suction of air to create a more optimal integration into the body of the yarn.

The air suction pulls the fibers in the yarn to give it softness and strength. The yarn is then twisted tight.

Because the fibers are drawn tightly into the yarn, good quality yarns can be produced from short length cotton because no fibers stick out. Another advantage is that the yarn can be produced at a higher speed than ring spinning

The elements of the t-shirt

The collar of the t-shirt

Necklines add support to the garment and give the t-shirt a more finished look. Chokers are usually one-by-one rib knits, although heavier fabrics or higher quality T-shirts may require two-by-two rib knits.

Neckwear fabrics can be tubular rib knits of specific widths or flat fabrics that need to be sewn.

Other t-shirt materials include tape or stitching, twill or another stiff fabric.

The binding reinforces the neckline and shoulder seams and protects them from tearing under tension. Alternatively, elastic can be used at the shoulder seams to keep them flexible.

The thread of the seams

Thread is of course an essential element in the sewing of any garment. Several types and colors of yarn can be used to make a single T-shirt.

Some manufacturers use white thread for the seams of all their t-shirts, regardless of color, eliminating the extra work of changing threads. The exposed topstitching is made with a thread color that blends with the fabric.

Colorless or monofilament thread can be used for hemming any color fabric, again eliminating the need to change threads often, although monofilament thread can be somewhat irritating to the skin.

The manufacturing process

Making T-shirts is a fairly simple and largely automated process. Specially designed machines integrate cutting, joining and sewing for the most efficient operations.

The most commonly used seams for T-shirts are narrow, overlapping seams, which are usually made by placing one piece of fabric over another and aligning the edges of the seams.

These seams are often sewn with an overlock stitch, which requires one needle thread from above and two looper threads from below. This particular combination of seam and stitch results in a flexible finished seam.

Another type of seam that can be used for T-shirts are bound seams, in which a narrow piece of fabric is folded around a seam, such as at the neckline.

These seams can be sewn together using a lockstitch, chain stitch or an overlock stitch. Depending on the style of the T-shirt, the order in which the garment is assembled may vary slightly.

Quality control

Most apparel manufacturing operations are governed by federal and international guidelines.

Manufacturers can also set guidelines for the company. There are standards that apply specifically to the t-shirt industry, which include proper sizing and fit, proper needles and seams, stitch types, and number of stitches per inch.

The stitches should be loose enough to allow the garment to stretch without causing the seam to break. Hems should be flat and wide enough to avoid curling.

T-shirts should also be inspected for proper application of necklines, which should lie flat against the body. The neckline should also recover properly after being slightly stretched.
