Have you ever had this experience? When buying clothes, the fabric on the label says 100% cotton, but the price and quality vary greatly. ?
Cotton is one of the most common textile raw materials in our daily life. However, as the scale of textile industrialization becomes larger and larger, the industrial division of labor becomes more and more complex. The depth of the industrial chain that ordinary textile workers can get involved in is very limited. Even if they work in the textile industry for a lifetime, they will not mention “cotton” every day. I don’t really understand or understand the truth behind the various quality problems in cotton fabrics caused by the fabric raw materials themselves. For this reason, I will explain the problems that affect the quality of cotton fabrics in the future.
Cotton grades are different
Cotton is divided into Egyptian cotton, Xinjiang cotton, American cotton, etc. according to its origin, and into fine-staple cotton and long-staple cotton according to its length. The average length of fine-staple cotton is 28 mm, and the average length of long-staple cotton is 35 mm. Only a handful of 7A super long-staple cotton can reach more than 40 mm. Fine-staple cotton has short fibers and can generally only spin yarns with a count of less than 80, while long-staple cotton can spin yarns with a count of more than 100.
Many people may ask, is Xinjiang long-staple cotton better? Which is better: American horse cotton or Egyptian long-staple cotton? Dashu believes that in terms of length, some long-staple cotton in Xinjiang can be called top-quality raw materials, Egyptian long-staple cotton has good stability, and the quality of American Pima cotton has declined in recent years.
Spinning Different yarn technology
Good cotton also requires good spinning technology. We often hear that fine cotton The concept of carding is that during spinning, the combing machine removes short fibers and impurities in the cotton, greatly improving the texture, luster, and strength of the yarn. At the same time, spinning also includes compact spinning, ring spinning, siro spinning, etc. Yarns spun tightly have less hairiness, higher strength, and are less prone to pilling.
yarn Different count densities
High-count yarn fabrics are thinner than ordinary yarn fabrics. Below 40 yarns are ordinary yarns (including 40 yarns), and above 80 yarns are high-count yarns. Of course, the higher the yarn count, the more expensive the cotton yarn is. Many merchants just bully you because you don’t understand, so those Taobao products that only sell for about 100 yuan, with so-called high-count and high-density fabrics marked on them, are basically deceptive tricks.
” If you like fabrics that feel good and soft, be sure to choose high-count and high-density fabrics, because the yarns are finer, so the fabrics are softer.”
Fabric Organizations are different
For the same yarn count, satin weave is better than twill weave, and twill weave is better than plain weave. Because the satin yarn has a large interweaving span, it has the best softness, stronger luster, and is more beautiful. The disadvantage is that it is easy to scratch, so it is best not to touch it with any sharp objects when using it. Of course, it does not mean that plain weave is not good. For example, plain weave is used to make duvet fabrics. Plain weave with high count and density can effectively prevent velvet, so the key is to look at the use of the product.
Dye Different materials
For cheap fabrics, the first consideration is cost, so inferior dyes will be used. The fabric itself will have problems such as formaldehyde, PH value, color fastness, and decomposable aromatic amine carcinogens exceeding the standard. These have been exposed a lot online in recent years. It is recommended Everyone still needs to choose cheap clothes carefully. After all, unhealthy clothes are like a chronic poison.
Of course , there are also some factors that determine the quality of the fabric, which are the processes in the production process, such as trimming, singeing, stretching, calendering, etc. The specific technical details all determine the cost.
