Advantages of canvas bags

Canvas bag. After my country promulgated the "plastic limit order" in 2008, people advocated environmental protection, canvas bags gradually entered daily life, and designers added fashion elements to them, which made canvas bags gradually become popular.

Canvas bags are more environmentally friendly. They are taken from nature and can be degraded. They are expensive and difficult to implement. However, their durability and firmness are much higher than non-woven bags. The cost performance is still very high, but the cost Too high, not suitable for large-scale promotion, so non-woven bags are not popular

The advantages are as follows：

1. The material of the canvas bag is the same as the material of the cotton bag. Cotton is taken from nature, and it is said that it is of course environmentally friendly;

2. Eco-friendly canvas bags, the biggest cost is the fabric. Some non-woven bags use eco-friendly ink. Generally, they will not cut corners to save a little money (unless they are fooled by the manufacturer). It can also be called here. It's environmentally friendly;

3. Durable and durable. I noticed that the fabric of the eco-friendly canvas bag that has been used for two years is not damaged in any way, but the thread is opened in some places (sometimes it is pressed by heavy things, and the manufacturer does not do it well), so the workmanship is exquisite manufacturer Yes, this is from the publicity time;

4. Canvas eco-friendly bags have more fabrics and more textures, most of which are fine and smooth. The printing and imaging effect is very good.

5. It is also easier to clean, and there will be a little deformation after washing, because pure cotton will shrink. This is much stronger than non-woven fabrics.

Canvas: A thicker cotton or linen fabric. Named because it was originally used for sails. Generally, plain weave is used, and a small amount of twill weave is used. Multi-strand yarns are used for warp and weft yarns. Canvas are usually divided into two categories: coarse canvas and fine canvas. Coarse canvas, also known as tarpaulin, is commonly woven with No. 58 (10 English) 4-7 strands. The fabric is strong and resistant to folding and has good waterproof performance. It is used for automobile transportation and open-air warehouse cover and tents in the field. Fine canvas warp and weft yarns are generally 2 strands No. 58 to 6 strands No. 28 (10 British counts/2 to 21 British counts/6), which are used to make labor protection clothing and its supplies. After dyeing, it can also be used as fabrics for shoes, travel bags, backpacks, etc. In addition, there are rubber canvas, shielding canvas for fire and radiation, and canvas for paper machine.

1. Canvas yarn count:

To put it simply, yarn count refers to the thickness of the yarn. At present, the "imperial system" is commonly used in China: one pound (454 grams) of cotton yarn (or other component yarn), the length is 840 yards (0.9144 yards/meter) ), the fineness of the yarn is one piece. If one pound of yarn has a length of 10×840 yards and a fineness of 10 yarn counts, the representation method of the yarn count is the English letter "S". The representation method of a single yarn is: 32 single yarn - -----It is expressed as: 32S strands are expressed as: 32 strands (two strands twisted in parallel) are: 32S/2, 42 strands and 3 strands are twisted as 42S/3.

2. Canvas density:

The calculation unit of canvas fabric density is in metric system, which refers to the number of warp and weft yarns arranged within 10cm. The density directly affects the appearance, feel, thickness, strength, flexural resistance, air permeability, abrasion resistance and thermal performance of the fabric and other physical and mechanical indicators. At the same time, it is also related to the cost of the product and the size of the production efficiency.

(1) Direct measurement method

The direct measurement method is accomplished by means of a cloth mirror or a fabric density analysis mirror. The length of the scale of the fabric density analysis mirror is 5cm. Below the analysis lens, a long glass sheet is engraved with a red line. When analyzing the fabric density, move the lens and align the red line on the glass sheet and the red line on the scale at the same time. Between the yarns, use this as the starting point, and count the yarns while moving the lens until the 5cm scale line is the same. The number of output yarns multiplied by 2 is the density value of the 10cm fabric.

When counting the number of yarns, the starting point should be the center between the two yarns. If the count reaches the end, it is more than 0.5, and if it is less than one, it should be counted as 0.75; if it is less than 0.5, then Calculated by 0.25. Generally, 3-4 data should be measured for fabric density, and then take the arithmetic average value as the measurement result.

(2) Indirect testing method

This method is suitable for fabrics with high density and regular weaves with small yarn characteristics. First, after analyzing the fabric weave and the number of weaving loop warp yarns (the number of weaving weft yarns), then multiplying by the number of weaving loops in 10cm, the product obtained is the warp (weft) yarn density.

3. Canvas weight:

Gram weight: refers to the weight of one square meter of cloth in grams. "Ounce", "An" or "OZ" knitted canvas for woven canvas fabrics generally use grammage (g/m2)

Its conversion is that 1 ounce is equal to 28.375 grams. However, it is generally 28.35 grams on the weighing machine, which is related to the yarn count and the warp and weft density of the fabric. The thicker the yarn, the thicker the cloth and the greater the weight of the fabric.

This has nothing to do with the density of the yarn weaving, but ounces are used for thicker fabrics. For example, denim canvas must be measured in ounces. In fact, you can also understand that ounces are used for thicker yarns. But now it is generally used in denim and canvas.

The eco-friendly canvas bag has many styles and new styles. It can be used as a general eco-friendly shopping bag as well as a corporate advertising and promotional gift.

Canvas bag is a kind of fashionable eco-friendly cloth bag. This kind of bag is very demanding in terms of workmanship and material. Otherwise, the high-end effect cannot be produced, but it will make people feel that it is nondescript.

We have our own canvas fabric production factory, which can directly control the quality of the fabric, as well as the canvas bag processing factory. If you have customized canvas bags, please contact us.
