Understand The Fabric Of Jeans - Denim, And How To Choose High-Quality Jeans

Denim fabric is generally made of cotton yarn with a twill weave using a yarn-dyed process. It is a type of cotton twill. If you look closely at the denim, you can clearly see the diagonal grain. Today's denim fabrics have also developed into cotton, wool, silk, linen, and chemical fiber blends, but they are mainly made of cotton, cotton-polyester blends, and cotton-span blends. The higher the spandex content, the better the elasticity.

Due to different yarn thickness and textile density, stretch denim fabric can be divided into three categories: light, medium and heavy. Light cloth weighs 200-340 grams per square meter, medium-sized cloth weighs 340-450 grams per square meter, and heavy cloth weighs more than 450 grams per square meter. Square, the heavier and thicker the fabric, the better the wear resistance and firmness.

The older it is, the better it tastes: This characteristic of denim is mainly due to the fact that its yarn dyeing process is different from other fabrics. Generally, yarn dyeing is soaked in dye so that the dye can penetrate into the yarn. The inside of the denim yarn uses a process called "indigo dyeing". To put it bluntly, it only dyes the surface of the yarn, and indigo is a non-solid color. With wear and constant friction, the surface The indigo will gradually fade, and the white yarn will slowly appear again. That’s why jeans become more and more white and tasteful. Some jeans have a lot of white spots when they are bought. This is because the manufacturer deliberately whitens them, mainly to create an old-fashioned style. It is also partly caused by white yarn being woven into them.

Versatile with all kinds of clothes: There are two main colors of denim, one is black denim fabric (black with a little white), and the other is indigo fabric (blue with a little white). Black and white are both achromatic, and Clothes of any color match harmoniously, and indigo can be said to be a color that is popular among fashion circles, which means it is fashionable no matter how you wear it. These characteristics of denim create the advantages of denim and are also the reasons why it is loved by the public.

How to choose good denim jeans

1. See with your eyes. A good denim fabric, whether it is front or back, must be very refreshing, with clear lines, even and straight lines, and tight arrangement. There should be no excessive black spots and other flying impurities woven into it. The white yarn will Slightly yellow, those pure white and reflective ones must be polyester chemical fiber. If it is sand washed, it will have a nostalgic effect, and the weft yarn on the bottom will appear yellow, which is normal.

2. Touch with your hands. Hand touch mainly relies on your hands to feel the fit and texture of the denim fabric. When touching, you should not just pinch with your fingers, but use your entire palm to cover the jeans and slide them up and down repeatedly, so that you can feel the fit of the fabric more deeply. A good denim fabric should be smooth and not rough.

When you touch it with your hands, it doesn’t mean that softer is better. The yarn count used in denim is not high, so it cannot be very soft. Some high-end denim will be harder because the yarns are arranged too tightly, while denim with high twist and good firmness will also be harder. Those Very soft denim is basically treated with softener or liquid ammonia during the washing process. Generally speaking, denim fabric should rely on its own natural characteristics to achieve a close-fitting style. If it relies too much on chemical treatment to achieve a soft effect, it will actually be detrimental to the texture of the fabric and human health.

3. Smell with your nose. Get close to the fabric and smell it. Good denim fabric should not have any irritating or other chemical odors. Those with special odors are caused by excessive chemical processing.

Through the three steps of seeing, touching, and smelling, I believe everyone should be able to initially judge whether a piece of denim is a good fabric. In addition, good denim fabrics should not only be beautiful in appearance, comfortable and close-fitting, wear-resistant, moisture-wicking, and wrinkle-resistant, but the style of denim that becomes more beautiful as it is washed and tastes better as it gets older should also be fully reflected.
