How is stretch denim made

Jeans lexicon

COTTON
Cotton is a very resistant natural fiber. This is what the jeans fabric is made of. For the plant to thrive properly, it needs a lot of sun and about 200 frost-free days. Cotton is very soft, but particularly tear-resistant and absorbent. It can be easily bleached, colored and printed.

BELL BOTTOM
A jeans style - tight around the waist and thigh that continues from the knee down. This style was especially popular in the 70s. The term "Bell Bottom" arose from the shape, viewed from the side.
BOOTCUT / BOOTLEG
The waistband and thighs have a narrow cut, the leg is flared, so it becomes wider at the bottom so that there is space for boots under the jeans.
BUTTON FLY
Is the original form of closure of the jeans: the button placket, as you can still find it today on Levi's 501, for example. In the first years of jeans production, it was the only practicable fastening system.
CINCH BACK
The cinch back (pronounced: / sɪntʃ bæk /) are two straps with buckles on the back of the jeans, which are attached directly under the waistband. The cinch back was used to tighten the pants at the hips before the belt caught on in the mainstream. From the 1940s onwards, belts became more and more popular and ribbons were therefore largely dispensed with. With the interest in the vintage style, however, the cinch backs also came back on certain jeans models.
COLORED DENIM
As the name suggests, this is about color, color, color. Whether yellow, green, turquoise or more subdued spicy tones - everything that pleases is possible here. In general, the term therefore describes all jeans whose denim has been dyed with a color other than indigo blue, gray or black.
DARK DENIM
Denim that goes through several dyeing processes or is dyed with a particularly dark indigo dye to obtain a very dark blue.
DENIM
Denim is a very robust cotton fabric with a twill weave, from which Levi Strauss later made the first classic jeans. Traditionally, a warp twill is used for denim in which only the warp threads are dyed with indigo, but the weft threads are undyed.
The word "denim" comes from the phrase "Serge de Nîmes" (French: "fabric from Nîmes [city in France]") and has been shortened over time so that only the short word "denim" is used.
INDIGO
Indigo is a natural, blue dye. It was originally obtained from the indigo plant and was mainly used as a dye for jeans. In 1870 the fully synthetic production of indigo succeeded for the first time and 27 years later the dye could be produced artificially by BASF for the first time in large quantities and was also sold commercially. The characteristic features of indigo are the good color fastness to water and light and a continuous, gradual fading. Its inability to completely penetrate the fibers allow the jeans to always look unique.
CRUMPS
In order to prevent the jeans from shrinking in the washing machine, the fabric web is pretreated before dyeing and cutting. The fabric is allowed to shrink by approx. 10% with water or hot steam. Then it is stretched and then pushed back together - this is how the denim reaches its final size. This treatment means that hardly anything can happen to the jeans the next time you wash them if you follow the most important care tips. In contrast to standard jeans, raw denim is not pretreated, i.e. within the first three washes it must be expected that the pants will shrink a bit.
LOOSE FIT
Wide-cut jeans that give plenty of legroom and are casual. The cut can taper a little towards the bottom or run almost in a straight line.
RAW DENIM
Raw denim (also known as dry denim) is a stiff, unwashed denim that has been dyed with indigo - a pair of jeans, so to speak, that goes back to its origins. Raw denim only gets its own unique properties through wear and tear, e.g. the development of wrinkles on the seat or in the back of the knees and natural abrasion on the back pockets, knees, seams and hems.
The more the jeans are used, the more distinctive is the individual used look that becomes apparent on the fabric after a while. By the way: Real lovers wear their raw jeans for 6 months without washing them, so that clear signs of wear and tear appear (the so-called "breaking in") and the color is not evenly washed out right from the start. So maybe you shouldn't start registering in midsummer. Against the smell you can put the jeans in the freezer overnight, this kills the bad smelling bacteria. Since the pants are completely unwashed, they can still shrink and rub off. Here in the Yeans Hall you can find raw denim from brands like G-Star, Nudie and Edwin.
SELVEDGE / SELVAGE DENIM
Selvedge (GB) or Selvage (US) denim is a type of denim that forms a 'natural' selvedge. Since this type of production is complex, it represents a quality feature that can only be found in high-quality jeans. The selvedge edge is located on the inside of the trousers and is therefore only visible when the trouser legs are rolled up.
The word comes from the Engl. "Self-edge" and thus describes the natural formation of the edge. It is created because the elaborate classic weaving process is used for selvedge denims so that the jeans cannot fray. In addition, this method requires significantly more material, as the fabric is woven more densely and the trousers are therefore much more resistant. The edge is usually provided with a colored thread (Levi's: red; Lee: green; Wrangler: yellow), which was previously used by the manufacturer to distinguish the balls of fabric from different brands.
SLIM / SKINNY FIT
Tight, figure-hugging fit, also known as skinny jeans. The step up of the slim fit is the skinny jeans, which are cut even tighter.
STRAIGHT FIT
Also known as a regular fit, jeans with straight legs and a normal high waist. The jeans have a normal cut and of course have the classic five pockets
STRETCH DENIM
Denim to which an elastic yarn has been added (e.g. elastane) to give the fabric a certain elasticity. Often there is stretch in skinny jeans to make them really tight. But stretch denim is also popular for greater comfort and convenience. Only a very small amount of elastane is necessary to achieve a great effect: 3% stretch makes jeans 15% stretchable.
TAPERED FIT
The cut is reminiscent of carrot trousers, as the jeans have a loose hip fit on the buttocks and they are also cut casually on the thighs, while the legs are tapered.
VINTAGE JEANS
Is a really old, historical pair of jeans that has either been worn or has been kept in stock in its original condition. The vintage jeans should not be confused with the vintage look.
VINTAGE LOOK
Denim treatment in which a worn and very worn look is artificially created through heavy washes, brushing, etc., so that the jeans look old
ZIP FLY
The modern counterpart to the button placket: the zipper. It began its triumphal march in the textile sector in the 1920s, as it enables trousers to be opened and closed more quickly. For this reason, the zipper is now often used instead of the button placket.
