Judging the quality of canvas bag from these five points

1、 In terms of fabric, backpack manufacturers mainly use canvas, corduroy, woolen velvet and other fabrics. In winter, they will add some artificial wool. Canvas of good quality will be used. Corduroy fabric has even texture and delicate feel, which is not very smooth in comparison.

2、 In terms of ingredients, compared with leather bags, cloth bags are not firm in shape and are easy to deform. Therefore, when producing cloth bags, a layer of non-woven fabric (Shengtang Capital: the raw material used by girls to compress facial mask) is usually pressed on the fabric to stabilize the shape of the bag. The heavier the non-woven fabric, the higher the price, the better the shape of the bag is fixed. Generally speaking, when the hardware ingredients are the same, the heavier the cloth is, the better the shape of the bag is.

3、 In terms of lining, the lining of pure cotton and silk cotton is stronger than that of chemical fiber, and it is not easy to draw. Maybe we often encounter this situation: the appearance of the bag is not bad, but the lining is broken first, so the lining is very important when purchasing the bag. Some brand bags will have brand logos on the lining, of course, the price will also increase accordingly.

4、 In terms of workmanship, the finer the stitches are, the stronger the bag is, and the easier it is to open the thread.

5、 In terms of hardware ingredients, such as zippers, rings, hooks, etc., the backpack manufacturer Grace Leather now generally uses copper, which is also heavy.
