Material Used to Make Jeans

Common to all the jeans that are manufactured, they are made of a so-called twill weave. One can say that this is a subcategory of woven fabrics but it has a number of characteristics. Woven fabrics, to begin with, include fabrics constructed of yarn from two directions intertwine.The yarn that runs horizontally along the fabric called weft yarns while passing vertically called warp. The denim is the vertical warp that is colored while the weft is usually colorless; It is partly this that gives denim its prominent diagonal appearance. The other and main reason denims diagonal appearance, the aforementioned kypertvävens construction. On the left is illustrated the construction of twill weave denim is made of; the black boxes symbolizing the colored vertical warp and the white of the undyed weft.

To the left is the most basic structure of woven fabrics, also known as plain weave. It is because of kypertvävens construction denim is dominated by the color on the outside but looks the other way around on the inside. The reason why denim is often blue is the original stained with indigo, which is a natural color pigments from India which was cheap and easy to work with. During the 1900s, however, was replaced indigo largely from synthetic alternatives when they are even cheaper and more easily worked.

However, there are differences in different kypertvävar. The shown above is called the right-hand twill to the diagonal pattern extends upwards right. This type is most common because it is denser and more uniform unlike the left hand twill that contrast is softened. The reason for this is that the yarn used in weaving composed of two threads which typically are twisted about each other to the left. An easy way to determine if you are wearing a pair of jeans with the right or left hand twill is to put your palms on the thighs with your thumbs inward groin and see if the diagonal pattern of the fabric follows the right or left index finger. If it follows the right index finger, you have a fabric made in the right-hand twill and vice versa. It has the last 15-20 years has become increasingly common stretchigare fabrics in jeans. This will be possible thanks to a small amount (usually 2-5%) elastic fibers are spun into yarn, resulting in a softer feel. Frequently such fibers are Lycra and elastane.

There are of course factors that distinguish jeans than more. Although the fabric is woven in the same way, the properties of various fabrics separated. Among hardcore jeans enthusiasts talk often about the fabric, or more often oz (ounces). This relates to how high density fabric is, that is how much yarn available on a particular surface. In the case oz (most common) this about how much a square yard of fabric weight in ounces (one ounce is approximately 28.35 grams). To put this in perspective is often said that the fabrics between 8 and 9 oz are lightweight fabrics suitable for summer hotter temperatures. Most of the jeans manufactured today have a fabric that weighs between 11 and 13 oz. Some Japanese weaving manufactures denim jeans which weigh upwards of 25 oz; these are so serious that they can safely stand up for themselves.

Another term appearing in about jeans is whether they are made in-selvage denim or not. Selvage-Denim is a fabric woven on looms more primitive than that industrialization brought. Unlike a modern projectile weaving broad woven fabric pieces Selvage-denim old shuttle looms is considerably narrower; about 21 to 32-inch to be precise. The name comes from the selvedge fabric at weaving these old looms itself create finished edges (self-EDGE), unlike more modern looms where the fabric is cut off at the edges and are prepared afterwards. An advantage of this is that it minimizes the risk that the fabric will recover, however, so the production is considerably more time-consuming and that the fabric becomes less ideal. Most skyttelvävstolarna be found today in Japan as American jeans manufacturer in the 50s went over to the modern projectile looms to meet the rising demand. The Japanese occupied the production of denim on skyttelvävstolar seriously back in the ’80s because they appreciated the different texture of the fabric and the way a selvedge fabric age on. What has become selvage denims-sized signs and what many appreciate is the edge that is visible on byxslaget, but true denim enthusiasts care most about the fabric. Today, virtually all premium brands no jeans model which is manufactured in-selvage denim.
