What are the differences in raw materials between cotton bags and canvas bags?

Cotton bags and canvas bags in the cloth bag category, we can all call them cotton bags, and they all belong to environmental protection bags. The raw materials are all woven from pure cotton, which is easy to fall in the natural environment and will not pollute the environment. However, they also have differences, that is, canvas bags are generally thicker than cotton bags. Then the environmental protection bag manufacturers will show you the difference between the raw materials of cotton bags and canvas bags?

1. Cotton cloth:

Cotton cloth is a kind of woven fabric with cotton yarn as the raw material, and different varieties are derived due to 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 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, which has the characteristics of softness, moisture absorption, breathability, and warmth. Its disadvantages are easy shrinkage and wrinkle.

There are a wide variety of cotton cloth, common ones are plain cloth, poplin, hemp yarn, twill, thread, velveteen, corduroy, etc. Cotton cloth is a necessity of people’s daily life. It is widely used in clothing, bedding, interior goods, interior decoration, packaging, industry, medical treatment, military, etc.

2. 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 used the name "canvas" to make sails. At present, as far as China is concerned, because hemp raw materials are relatively small, we generally think that cotton is used as raw material. Therefore, it can be said that canvas is also a kind of cotton under the big category. The biggest difference between canvas and cotton fabric is that the warp and weft yarns of canvas are composed of 2 or more strands, while cotton fabrics are mostly single strands.

This also leads to the rough appearance of the canvas and the denser cotton cloth. 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 firm texture, wear resistance, compactness and thickness, and canvas has strong and good waterproof characteristics. Therefore, canvas is widely used in cloth bags, clothing, footwear, automobile transportation, luggage and other industries.
