　　1。 Eyes. Maybe some friends have this experience. When they go to the market with some friends who know bamboo denim very well, they are generally not interested in many fabrics after a glance. They may show great interest in fabrics found occasionally. When you ask them why they know at a glance whether it is good or bad, they generally cannot explain it by themselves. The feeling is the feeling of the eyes. Like practice makes perfect, you can understand some jobs at a glance. Therefore, in the market, it is impossible for us to bring jeans to special arrangements for scientific testing of prestige, so this vision accumulated from years of experience is very important. Vision depends entirely on one's professional level. Just like football players, their ability in front of the door comes from ordinary training level. Good denim fabric, the style of the fabric must be very fresh and clear, and we can see the difference in the place of washing, especially in the place of hand rubbing. Turn over the bottom cloth to see the weft yarn. The lines should also be clear and uniform, without too many black spots and other flying flowers woven into impurities. The yarn color is yellow in white (that is, the white flowers are reflective and need to be mixed with chemical fibers). If you nostalgic, the weft yarn at the bottom will show yellow, which is normal. Denim fabric must depend on the effect of washing. Why do the road goods outside like embroidery and beads instead of playing in the water? In fact, they are worried that the defects of their fabrics will be exposed after washing. Unfortunately, many customers who do not know the product still think that these jeans are very fashionable. Friends who know a little about denim fabric know that the defective fabric, especially after washing, feels very bad. However, good fabrics, whether simple or messy, have a high-end feeling that makes people can't put it down.

　　2。 Hand contact. Hand feeling mainly relies on the hand to feel the tightness and texture of the fabric. Generally, many customers like to pinch the fabric with their fingers. In fact, this is not scientific. They should cover the jeans with their whole palm and slide them up and down repeatedly, so that they can feel the closeness of the fabric more deeply. Many customers think that the softer the slub denim, the better. In fact, this is not scientific. The hardness and softness of slub denim are related to the fabric arrangement style (thicker texture, thicker handle) and yarn performance (thicker twist, different handle of cotton yarn and blended yarn). The finishing process generally plays an obvious role in the softness and hardness of slub denim, such as adding softener and liquid ammonia. Processing will affect the feel of the fabric. In general, jeans should rely on their own natural characteristics to achieve a snug style. If they rely too much on chemical treatment to achieve softness, in fact, it will not have much positive impact on fabric quality.

　　3。 Nose. Close to the smell. Good fabric should not have any irritating or other smell. It can also sleep safely when used for pillows. I have a feeling of meeting cowboy friends in the wholesale market. As soon as I enter the market, the taste is choking. Fabric rings are not environmentally friendly. It can initially be identified by sniffing. No peculiar smell is not necessarily environmental protection, but it is necessary to use the substandard fabric with peculiar smell. Through eyes, hands and nose, we can have a general understanding of the quality of denim fabric. If these three levels of fabric can not pass the test, it must not be a good quality denim fabric. However, it is not feasible to comprehensively and scientifically identify the quality of slub denim. It is necessary to send it to a special test arrangement because of its color difference, color fastness, environmental protection, fiber composition, abrasion resistance, burst resistance, tear resistance, shortening, slope resistance, and many other detailed analysis indicators. In terms of practicality, good slub denim should not only be reflected in high-end appearance, comfortable clothing, long life and other aspects, but also in moisture absorption, sweat resistance, wrinkle resistance and other aspects, and the older the more beautiful, the more tasteful washed.
