Portable lift rod canvas bag

The tripod portable lift rod is characterized by light weight; The collection height is low, the height range is large, the operation is simple, and it is convenient to carry; The company is also equipped with portable military canvas bag, which can be carried alone or put into the trunk of the car.

Canvas bag. After China issued the "Plastic Limit order" in 2008, people advocated environmental protection. Canvas bag gradually entered daily life, and designers added fashion elements to it, which gradually made canvas bag become popular.

 

Canvas bag is relatively environmentally friendly. It is naturally degradable, that is, it is difficult to implement with high cost. However, its durability and firmness are much higher than non-woven bag, which is very cost-effective, however, the cost is too high and it is not suitable for large-scale promotion, so it is not popular non-woven bag.

1. The material of canvas bag is the same as that of cotton bag, which is made of cotton and natural. As mentioned above, it is certainly environmentally friendly;

2. Environmental protection canvas bag, the biggest cost is fabric, some non-woven bag use environmental protection ink, generally do not cut corners to save that money (unless it is covered by the manufacturer), it is said that it can also be called environmental protection here;

3. Strong and durable, I noticed that the environmentally friendly canvas bag fabric used for two years did not have any damage, but some places were wired (sometimes heavy things were pressed, and the manufacturer did not do well), therefore, the workmanship is from a sophisticated manufacturer, which is from the time of publicity;

4. Canvas eco-friendly bag has many fabrics and many lines. Most of them are very delicate and smooth. The printing and imaging effect is very good.

5. It is easy 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 after it was originally used for sails. Generally, plain weave is mostly used, twill-weave is used for a small amount, and multiplied yarn is used for warp and weft yarn. Canvas is 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 firm and folding resistant, and has good waterproof performance, it is used for car transportation, covering outdoor warehouses and setting up tents in the wild. Fine canvas warp and weft yarn is generally 2 shares 58 to 6 shares 28 (10 English/2~21 English/6), used to make labor protection clothing and its supplies. After dyeing, it can also be used as shoes, travel bags, backpacks and other fabrics. In addition, there are rubber canvas, shielding canvas for fire prevention and radiation protection, and canvas for paper making machines.

1. Canvas yarn count:

In short, the yarn count refers to the thickness of the yarn. At present, what is commonly used in China is "English", that is, one pound (454 grams) of cotton yarn (or other component yarn), when the length is 840 yards (0.9144 yards/meter), the fineness of the yarn is one. If a pound of yarn, its length is 10 × 840 yards, and its fineness is 10, the representation method of yarn count the English identification mark is the English letter "S" The representation method of single yarn is: 32 single yarn ------- the representation method of 32S strand is: 32 strands (two lines and twist) are: 32S/2,42 3 strands and twist are: 42S/3.

2. Canvas density:

The calculation unit of canvas fabric density is measured in metric, which refers to the number of fibers arranged by weft within 10cm. The density directly affects the physical and mechanical indexes such as the appearance, hand feeling, thickness, strength, Flexural Resistance, air permeability, wear resistance and thermal insulation of the fabric, at the same time, it is also related to the cost of products and the size of production efficiency.

(I) direct measurement method

Direct measurement method is completed by cloth mirror or fabric density analyzing prism. The A scale length of fabric density analyzing prism is 5cm. Under analyzing prism heads, a red line is engraved on a long strip glass cover. When analyzing fabric density, move the lens, align the red line on the glass cover and the red line on the scale between the two yarns at the same time, taking this as the starting point, and move the number of yarn roots on the Lens side until the 5cm scale line is used. The number of yarn roots output multiplied by 2 is the density value of 10cm fabric.

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

(Ii) indirect test method

This method is applicable to regular woven fabrics with high density and small yarn size. Firstly, after analyzing the fabric structure and its tissue circulation warp number (the number of tissue circulation weft), and then multiplying by the number of tissue circulation in 10cm, the obtained product is the warp (weft) yarn density.

3. Canvas weight:

Gram weight: refers to the weight gram of a square meter of cloth. Woven canvas fabric with "OZ", "an" or "OZ" knitted canvas generally uses gram weight (g/m2)

Its conversion is that 1 ounce is equal to 28.375 grams, but it is usually 28.35 grams on the weighing machine, which is related to the yarn count and thread count. The thicker the yarn, the thicker the cloth, and the heavier the gram.

This has nothing to do with the yarn density of the fabric, but ounces are used on relatively thick fabrics. For example, denim canvas must be measured in ounces, in fact, you can also understand it as an ounce for yarn weaving, but now it is usually used in denim and canvas.

Environmental protection is canvas bag, with many styles and new styles. It can not only be used as a general environmentally friendly shopping bag, but also as a premium gifts for enterprises.

Canvas bag is a fashionable and environmentally friendly cloth bag. This kind of bag has high requirements in terms of workmanship and material. Otherwise, the high-end effect will not come out, but it will make people feel nondescript.
