Cotton and linen bags although the material is made of pure cotton textile, easy to degrade in the natural environment, and will not pollute the environment, but they also have a different place, that is, the thickness of the canvas bag is generally greater than the cotton and linen bag.
First, cotton and linen bags:
The material is a woven fabric made of cotton yarn, because of the different arrangement standards and different post-processing methods, and the different varieties derived from the concept of cotton is very broad, it can be said that all raw materials are fabrics woven with cotton yarn can be called cotton. But to understand in daily life, it is generally thought that cotton is made of a single strand, relatively fine cotton yarn textile, with soft, moisture absorption, breathable, warm and other characteristics, its defect is easy to shrink, easy to wrinkle. There are a wide variety of cotton cloth, common plain cloth, poplin, hemp yarn, twill, thread, velvety, corduroy and so on. Cotton is a necessity of People's Daily life, it is widely used in clothing, bedding, indoor goods, interior decoration, packaging, industry, medical, military and other aspects.
Second, canvas bag:
The material of the canvas bag is a relatively thick cotton fabric or hemp fabric, and most of the standard yarn of the canvas bag is thicker than the general cotton yarn. As early as the eighth century, Europeans used to make sails and got the name "canvas". At present, in terms of domestic, because the hemp material is relatively small, it is generally made of cotton, so it can be said that canvas is also a kind of cotton under this large field.
The biggest difference between canvas and cotton is that the warp and weft yarns of canvas are composed of two or more strands, and cotton is mostly a single strand, which also leads to the appearance of the canvas bag is relatively rough, and the cotton and linen bag is relatively tight. Other canvas generally choose plain weave weave, rarely choose twill weave, which also brings convenience to the difference between canvas and cotton, because the canvas is multi-thread weave, so the texture is firm, wear-resistant, tight solid, and the canvas has solid and good waterproof characteristics, so the canvas is widely used in cloth bags, clothing, footwear, automobile transportation, luggage and other industries.
Due to its solid and durable characteristics, canvas fabrics were more used in the early days to manufacture military tents, parachutes and so on. With the progress of science and technology, textile technology has been greatly improved, and the types of canvas have gradually increased and are more widely used. In the 21st century, into the era of environmental protection, the environmental fabric of canvas has been more recognized, and carrying new fashion concepts, into the field of fashion. Canvas bags have become a popular fashion item. However, when buying canvas bags, we often have misunderstandings, some consumers think that the thicker the fabric of the canvas bag, the better the quality, but it is not, the quality of the fabric has nothing to do with the thickness of the fabric, the amount of cotton and treatment is an important factor in determining the quality of the fabric, the fabric of the Republic of canvas after a variety of technical treatment of high-quality canvas fabric is not only solid and durable, while the feel is more delicate, Soft, better air permeability, the lightness of the fabric also reduces the weight of the original heavy canvas bag.
