How to distinguish between canvas bags and cotton bags?

Canvas bags and cotton bags, we can all call them cotton bags, and they are all environmentally friendly bags. The raw materials are all made of pure cotton, which is easily degraded in the natural environment and will not cause environmental pollution. However, they also have differences, that is, the thickness of canvas bags is generally larger than that of cotton bags. Let us introduce the respective characteristics of these two kinds of bag raw materials:

Canvas: Canvas is a relatively thick cotton fabric or linen fabric. Most of the yarns of canvas are thicker than ordinary cotton yarns. As early as the eighth century, Europeans were named after they were used to make sails. "canvas". At present, domestically, due to the relatively few raw materials of hemp, we generally think that cotton is used as the raw material, so it can be said that canvas is also a type of cotton cloth. The biggest difference between canvas and cotton is that the warp and weft yarns of canvas are composed of 2 or more strands, while cotton is mostly single strand. This also leads to the rougher appearance of the canvas and the finer texture of the cotton. In addition, canvas is generally woven in plain weave, and twill weave is used in rare cases, which also brings convenience to distinguish canvas from cotton. Because the canvas is woven with multi-strand threads, the texture is firm, wear-resistant, compact and thick, and the canvas has strong and good waterproof properties. Therefore, canvas is widely used in cloth bags, clothing, footwear, automobile transportation, luggage and other industries.

Cotton cloth: Cotton cloth is a kind of woven fabric made of cotton yarn. Different varieties are derived due to different tissue specifications and different post-processing methods. The concept of cotton cloth is very broad. It can be said that any fabric made of cotton yarn can be called cotton cloth. But to understand it in the scope of daily life, it is generally believed that cotton cloth is woven from a single strand of relatively fine cotton yarn, which has the characteristics of softness, moisture absorption, ventilation, and warmth. Its disadvantage is that it is easy to shrink and wrinkle. There are a wide variety of cotton cloth, such as plain cloth, poplin, hemp yarn, twill, woolen cloth, velveteen, corduroy and so on. Cotton is a daily necessities, it is widely used in clothing, bedding, interior products, interior decoration, packaging, industry, medical, military and other aspects.
