The difference between canvas drawstring bag and cotton drawstring bag
Do you also think that cotton drawstring bags and canvas drawstring bags are the same material? Actually not, although their raw materials are all woven from pure cotton, they are easily degraded in the natural environment and will not pollute the environment. However, they also have differences, that is, canvas drawstring bags are generally thicker than cotton drawstring bags.
1. Cotton drawstring bag
The material of cotton drawstring bag is a kind of woven fabric with cotton yarn as raw material, and different varieties are derived due to the different organization specifications and different post-processing methods. The concept of cotton cloth is very broad. It can be said that any fabric woven from the 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 single-strand, relatively thin cotton yarn. It has the characteristics of softness, moisture absorption, ventilation, and warmth. Its disadvantages are easy shrinkage and easy wrinkle. There are many types of cotton cloth, common ones are plain cloth, poplin, linen yarn, twill, thread, velveteen, corduroy, etc. Cotton cloth is a necessity for people's daily life. It is widely used in clothing, bedding, interior goods, interior decoration, packaging, industry, medical treatment, military, and so on.
2. Canvas drawstring bag: The material of the canvas drawstring bag is a thicker cotton fabric or linen fabric. Most of the yarns of canvas drawstring bags are thicker than ordinary cotton yarn. As early as the eighth century, Europeans used the name "canvas" to make sails.
The difference between canvas and cotton cloth is that the warp and weft yarns of the canvas are composed of 2 or more strands, while the cotton cloth is a mostly single strand. This also leads to the rough appearance of the canvas drawstring bag and the denser cotton bag. In addition, the canvas is generally woven with plain weave, and twill weave is rarely used, which also brings convenience to distinguish canvas and cotton. Because canvas is woven with multiple strands, it has a firm texture, wear resistance, compactness, and thickness, and the canvas has strong and good waterproof characteristics. Therefore, the canvas is widely used in cloth bags, clothing, footwear, automobile transportation, luggage, and other industries.
