Knowledge Of Textile Fabrics --- Soft Silk And Canvas

< p > > a href= "//www.sjfzxm.com/news/" > soften protein fiber < /a > is a protein modified cellulose fiber. Its raw material is protein and cellulose fiber. It is derived from the renewable green plants in nature and is a degradable environment-friendly fiber.

< /p >

< p > the current specifications for production are: 1D * 38mm 1.5D * 38mm 2D * 51mm 2D * 76mm 3D * 65 mm mm * * * * * *

5D * 102mm. < /p >

< p > soft silk protein fiber has the advantages of glossy softness, balanced moisture absorption, soft and comfortable, skin care, skin protection, protein, amino acids, UV protection, far-infrared rays, negative oxygen ions and other advantages. It is a cheap and high-quality textile material for replacing cashmere and improving the performance of wool products, and is also suitable for health care function of textile raw materials.

< p > canvas < /p >.

< p > a thicker < a href= "//www.sjfzxm.com" > cotton fabric < /a > or linen fabric.

It was originally named for sail.

In general, plain weave is used, a small amount of twill weave is used, and warp and weft yarns are used with multiple strands.

Canvas is usually divided into two categories: canvas and canvas.

The canvas is also called the cover cloth. It is commonly used in weaving 4~7 strands of No. 58 (10 British) fabric. The fabric is fast resistant and has good waterproof performance. It is used for covering motor vehicles and open warehouses and for tents in the wild.

Canvas warp and weft yarn is usually 2 strands 58 to 6 strands 28 (10 /2 to 21 /6), used for making labor protection clothing and its articles.

After dyeing, it can also be used as shoes, travel bags, backpacks and other fabrics.

In addition, there are also rubber canvas, canvas for fire protection and radiation protection, and canvas for paper machine.

< p > 1, Hobu Sa: < /p >

In short, P refers to the thickness of yarns, which is commonly used in China at present. It is "British style", that is, one pound (454 grams) of heavy cotton yarn (or other component yarn), with a length of 840 yards (0.9144 yards / meter), and the fineness of the yarn is one.

If the length of a pound of yarn is 10 x 840, its fineness is 10, and the expression of the yarn is.

The English symbol is the English letter "S" single yarn. The expression is: 32 single yarn, that is: the 32S strand line is expressed as follows: 32 strands (two threads and twists) are both: 32S/2, 42 3.

The root twisting is 42S/3.

< p > 2, canvas density: < /p >

< p > the density of canvas fabric is calculated in metric system, which refers to the number of yarns arranged in warp and weft yarns in 10cm.

The density directly affects the physical and mechanical indexes of the fabric such as appearance, handle, thickness, strength, folding resistance, permeability, abrasion resistance and thermal insulation. At the same time, it also relates to the cost and efficiency of the product.

< /span > < /p >.

< p > there are two ways to determine the density of warp and weft: < /p >

< p > (1) direct measurement method < /p >.

< p > direct measurement is accomplished by means of a cloth mirror or a fabric density analyzer.

The length of the scale of the fabric density analysis lens is 5cm. Under the analysis of the lens, a red line is carved on a long piece of glass. When analyzing the fabric density, the moving lens is aligned between the two red yarns on the red line and the scale on the glass. At the starting point, the number of the yarns on the edge of the lens is moved to the 5cm scale line.

The number of yarns multiplied by 2 is the density value of 10cm fabric.

< /p >

< p > when the number of yarns is counted, starting from the center of the two yarns, if the number reaches the end point, more than 0.5, while less than one, it should be calculated by 0.75; if less than 0.5, it will be counted by 0.25.

In general, 3-4 data should be measured in the fabric density, and then the arithmetic mean value of the fabric is measured as the result of the measurement.

< /p >

< p > (two) indirect test method < /p >

< p > this method is applicable to fabrics with regular density and large yarn size.

First, the number of warp yarns (the number of weft loops in tissue) is analyzed, then multiplied by the number of loops in 10cm, and the product obtained is the density of warp yarns.

< p > 3, < a href= "http://cailiao.sjfzxm.com/Matertial/show/default.aspx" > canvas < /a > weight: < /p >

< p > gram weight: the weight of a square metre of cloth.

For woven woven canvas fabric, use "ounce", "Ann" or "OZ" < /p >.

< p > knitted canvas is usually weighed (g/m2) < /p >.

< p > its conversion is 1 ounces equal to 28.375 grams, but on the cloth machine generally 28.35 grams, with the yarn and fabric weft density, the thicker the yarn, the thicker the cloth, the thicker the gram weight.

< /p >

< p > this is not much related to the yarn density of the fabric, but the ounce is used on the thicker fabric, for example, the denim canvas must be in the ounce. In fact, you can also understand that the yarn is coarser in the ounce, but now it is usually used in denim and canvas.

< /p >

< p > 4, canvas width: < /p >

< p > width: refers to the width of the weft of the canvas, which is commonly used in the world as "inch" or "", "such as" 47 ".

Commonly used in China is "centimeter" or "cm", such as "120cm".
