Including when we usually buy clothes, we will ask, is this made of cotton? As we all know, pure cotton clothes do not irritate the skin and are comfortable to wear. With the variety of fabrics and the varying quality, how should we identify pure cotton fabrics when choosing work clothes? Below, the editor will give you a brief introduction to science. It can be roughly divided into: look, smell, touch and burn. Purchasing staff can use these tips when selecting work clothes fabrics.
1. Take a look:
Pure cotton fabric has a lighter luster, is not highly reflective, and looks softer. The easiest thing is to check the label of the fabric to see if it is 100% cotton. For more detailed observation, you can:
① Look at the edges of the fabric: You can see the uniformity of the weave of the fabric by looking at the edges of the fabric. Unfold the fabric, and then carefully observe the edges of the fabric. If the edges of the fabric are neat, then the fabric The overall weave will be neat and the fabric will be good.
②Look at the grain: Look at the vertical and horizontal grains of the fabric. If the vertical and horizontal grains intersect vertically, the fabric is good. This kind of fabric is not only durable, but also resistant to deformation, ensuring that clothes stay crisp.
③Look at the luster: Generally speaking, pure cotton fabrics look too bright and hairless, and may be mixed with chemical fibers that irritate the skin. However, if the material is too dark, it does not have a sense of luxury and lacks wool. It has the luster it should have, but the quality of the wool is not high. Therefore, good quality materials have positive colors, even coloring, smooth printing, and natural and soft luster.
2. Smell it:
If the smell is too strong, it means it contains impurities. Usually chemical fiber fabrics have a medicinal smell, woolen materials have an oily smell, and the quality is not good. Pure cotton fabric does not have a pungent smell.
3. Touch it:
You can pull it to see the rebound of the fabric. Generally, the pulling range is small and the recovery is slow, which is a characteristic of pure cotton. The following types of fabrics can be roughly distinguished by observation and feel:
①Pure cotton cloth: The cloth has a soft luster, soft hand feel, poor elasticity, and is easy to wrinkle. If you pinch the fabric tightly with your hands and then loosen it, you will see obvious wrinkles, and the creases are not easy to return to their original shape. Pull out a few warp and weft yarns from the edge of the cloth and twist them to see if the fibers are of different lengths.
② Viscose cotton cloth (including rayon and fiber-rich cloth): The cloth surface has a soft and bright luster, bright colors, smooth and smooth texture, soft hand feel and poor elasticity. If you pinch the fabric tightly with your hands and release it, you will see obvious creases, and the creases are not easy to return to their original shape.
③Polyester cotton cloth: The luster is brighter than pure cotton cloth, the cloth surface is smooth, clean and free of yarn ends or impurities. It feels smooth and crisp, and has better elasticity than pure cotton. If you pinch the fabric tightly with your hands and release it, the creases will not be obvious and it can easily return to its original shape.
Four. Burn:
You can ask the manufacturer for a small piece of spare fabric to light and try. Pure cotton fabric is flammable and It ignites quickly, smells like burning paper, and appears into a fine and soft gray-black floc after burning. This method is intuitive and accurate. Pure cotton fabrics will not shrink when exposed to fire and usually burn slowly like paper. Observe the burned ashes. The color of the flame produced during burning is yellow. At the same time, the burning smell is similar to that of burning paper, and there is no peculiar smell. Generally, pure cotton materials will turn into powdery ash after burning.
The above are several methods that the editor has compiled for you to identify pure cotton fabrics when choosing work clothes. I hope it can help you. I wish everyone a happy work!
