How to identify the quality of denim fabrics
How to identify the quality of denim fabric. Many people who are not engaged in the production of workwear are not very clear. Here are some basic identification methods, hoping to be helpful to everyone.
Because the identification of the quality of denim fabrics can be said to be the most difficult level in identifying the quality of strong trousers. In order to achieve professional knowledge in this area, it is often more practical than theoretical. Moreover, denim fabrics are innovating every day, and new fabrics are constantly coming out. No matter how experienced people are, they must constantly be exposed to new things in order to Improve your identification skills.
Many friends have asked me how to quickly learn to check the fabric quality of trousers. I think that as long as the method is appropriate and there are professionals around to guide me, it will not be too difficult. It is possible to at least roughly identify the quality of fabrics.
My personal suggestion is that you go to those well-known denim brands and domestic first-line denim brand stores. Although not all of the fabrics of the above brands are very good, most of them are still very good. As long as you look more, compare more, look carefully, and compare carefully, I believe that if you look more, your eyesight will become more and more skilled. If you don’t look at high-quality things and only focus on the bulk goods in the wholesale market every day, I think if you stay in this industry for another ten or eight years, your professional level will not improve at all.
Many friends don’t know much about denim. When they see the relatively simple styles of well-known denim brands, they subjectively think that those brands are of poor quality and ugly. This is actually a sign of ignorance. Really high-end and high-quality sturdy trousers are those that look very simple, but the fabric and pattern are not blurry. When consumers truly understand the meaning of “the simpler the strong trousers, the better” and truly recognize this statement, I think everyone’s understanding of strong trousers has reached a new level.
How to identify the quality of denim fabric
1. Eye view
Some friends may have this experience. When going to the market with some friends who are very familiar with denim fabrics, they usually glance at many fabrics and then lose interest in looking at them. They may be interested in a fabric that they occasionally find. will show great interest. If you ask them why they can tell good or bad at a glance, they usually can’t explain it themselves. This feeling is the sense of sight. Just like practice makes perfect, if you see some things too much, you can get a general idea at a glance. Therefore, in the market, it is impossible for us to go to a specialized institution to conduct authoritative scientific testing of strong trousers, so this kind of visual experience accumulated through years of experience is particularly important. The quality of one’s eyesight all depends on one’s professional level, just like a casual footballer’s finishing skills all come from his usual training level.
Good strong trousers fabric, the fabric style must be very refreshing, the texture is clear, you can definitely see the difference in the washing area, especially in the areas where it has been wiped by hand. Open the base fabric and look at the weft yarns. The texture is clear and the lines are even. There are no excessive black spots or other impurities in the weaving. The color of the yarn is white with yellow (the kind of white stripes with reversed ends must be adulterated) chemical fiber), if it is made of nostalgic, the weft yarn on the bottom will appear yellow, this is normal.
The effect of denim fabrics after washing must be determined. Why do those popular products outside only like to make things like embroidery and beading, but don’t dare to do more complicated things in washing water? In fact, they are afraid of the effect after washing. , the inferior nature of its fabric is revealed. Unfortunately, many ignorant consumers still think that this kind of jeans is very fashionable. Friends who are a little familiar with denim fabrics all know that poor fabrics will feel like they are washed and wiped with water, which is really terrible. And good fabrics, whether they are washed simply or complicatedly, have a high-end feel that makes people fall in love with them.
2. Hand touch
Hand touch mainly relies on your hands to feel the fit and texture of the fabric. It is common for many consumers to pinch the fabric with their fingers. In fact, it is unscientific to do so. You should use your entire palm to cover the strong trousers and slide it up and down repeatedly to feel the fit of the fabric more deeply. Many consumers think that the softer the denim fabric, the better, but this is actually unscientific.
The softness and hardness of denim fabric are not only related to the fabric weave style (the denser the weave, the rougher the hand will feel), but also the characteristics of the spun yarn (the higher the yarn twist, the rougher the hand will feel. Cotton yarn and blended chemical fiber fabric yarn The feel is also different) In addition, the post-finishing process usually plays a significant role in the softness and hardness of denim fabrics, such as adding softeners, liquid ammonia treatment, etc., which will affect the feel of the fabric. Generally speaking, denim fabricIt should rely on its own natural characteristics to achieve a close-fitting style. If you rely too much on chemical processing to achieve a soft effect, it will not have much positive impact on the texture of the fabric.
3. Nasal listening
Listen close and listen. Good fabrics should not have any irritation or other odors. They can be used as pillows to help you sleep peacefully. Friends who sell large-scale goods in the wholesale market have experienced the smell of strong trousers as soon as they enter the market. The fabric ring is not environmentally friendly. You can make a preliminary identification by listening. If it has no odor, it is not necessarily environmentally friendly, but if it has an odor, it must be unqualified fabric.
Summary:
Through the three levels of sight, touch and hearing, you can have a general understanding of the quality of denim fabrics. If the fabric cannot pass these three tests, it will definitely not be a denim fabric with good quality. But to completely scientifically identify the quality of denim fabrics, relying on these three points is far from enough.
We must send it to a special testing agency for color differences, dyeing fastness, environmental protection, fiber composition, abrasion resistance, burst resistance, tear resistance, shrinkage, and tensile strength. Detailed analysis on slope…and many other indicators. In terms of usefulness, good denim fabrics should not only achieve high-end appearance, comfortable and close-fitting wear, and long service life, but also have good moisture absorption and perspiration resistance and wrinkle resistance, as well as a style that becomes more beautiful with washing and tastes better with age. manifestation.
