How much you know about the denim fabrics?

1. The origin of denim fabrics

Five hundred years ago, when Columbus discovered the New World, this tough and practical rough cloth had already appeared, and it was mainly used to make sails at that time. Because this cloth originated in Nimes, a small town in France, it was named “Serge De Nimes” in French.

5. Denim washing

General washing

Ordinary washing, change the washing we are familiar with to mechanization, the water temperature is about 60-90°C, add a certain amount of detergent, after about 15 minutes of ordinary washing, add softener to the clear water to make the fabric more Soft, comfortable, visually more natural and cleaner.

Stone washing / stone grinding (STONE WASH)

Stone washing is to add a certain size of pumice to the washing water, so that the pumice and clothes are polished, and the water level in the polishing tank is carried out at a low water level where the clothes are completely soaked, so that the pumice can be in good contact with the clothes. Yellowstone, white stone, AAA stone, artificial stone, rubber ball, etc. can be used for washing to achieve different washing effects. After washing, the cloth surface will appear gray and old, and the clothes will be slightly to severely damaged.

Enzyme Wash (ENZYME WASH)

Enzyme is a kind of cellulase, which can degrade the fiber structure at a certain pH value and temperature, so that the cloth surface can fade mildly and hair (produce “”peach skin”” effect), and obtain long-lasting softness Effect. Stones can be used together or instead of stones. If used together with stones, it is usually called Enzyme Stone Wash (ENZYME STONE WASH).

Sand washing (SAND WASH)

Use more alkaline and oxidative additives for sand washing, so that the clothes will have a certain fading effect and old feeling after washing. If it is equipped with a stone mill, a layer of soft and creamy white fluff will be produced on the surface of the cloth after washing, and then add some softener. It can make the fabric soft and soft after washing, thus improving the comfort of wearing.

6. The production and processing process of denim fabric

Ring spun denim

Ring spun yarn is a kind of cotton yarn, which is divided into air spinning (oe) and ring spinning (r). Ring spinning has improved the disadvantages of short spinning length, low production efficiency, and many knots of coarse-count yarn. The hand feeling and drape of ring-spun denim are better than air-jet yarn, and after washing, there will be bamboo knots. Shaped style, so that it has a stronger momentum of development.

Warp and weft slub denim

A yarn of the same thickness from top to bottom is called smooth yarn, and regular thick and thin we call it slub yarn, which can be divided into long and short slubs, and some denim also looks like bamboo on the surface. Knots, but thick and fine yarn. In addition, the cloth woven by ring spinning will also look like bamboo.

Ultra Indigo Dyed Denim

In the past, the indigo washing intentionally made the indigo dye penetrate the fiber core very shallowly, so that when the denim clothing is washed and processed, the extremely thin layer of dye on the surface of the yarn is rubbed off, exposing more white yarn core, making the color It fades quickly, so as to achieve the effect of fading immediately after a short period of scrubbing. Contrary to the indigo washing process in the past, it is required that the degree of penetration of the dyestuff is particularly good, so that the denim garment can obtain a deep and bright color after grinding.

Chromatic denim

The so-called chromatic denim is based on ordinary fabrics, after desizing and washing, and dyeing with reactive dyes again. Since the original warp yarn is blue, and the weft yarn is white without dyeing, the effect produced between the warp and weft yarns after re-dying is different, so there will be a special double-color effect. After this process is made into garments, there are more color registrations, and less color registration is done on fabrics. Because the secondary process is more cumbersome, the cost is also higher.

Assorted denim

Assorted-color denim is because there is only one blue color in the indigo dye spectrum for dyeing denim. Therefore, in order to obtain other colors other than blue, other dyes must be used for dyeing. It is usually dyed with reactive sulfur vat dyes, so it is called even-colored denim, also called colored denim.
