For some businesses, generally do not consider to fabric weight. And the fabric weight to understand roughly the weight of the fabric, is the significance of which can calculate the fabric cost and price. If calculating the fabric weight, it was based on the weight per meter, is refers to the finished fabric per meter of grams of weight. To introduce the following fabric weight calculation method.
Fabric weight calculation method is: the finished product weight per meter (g/m) = (meridian quantitative practising discount rate + parallel quantitative x x the discount rate) present dyeing and finishing shrinkage (1) the discount rate: smelting turnning yarn after dyeing and finishing (silk). Different fiber contains impurities is different, different technology will also make the same raw material refining different discount rate. Commonly used raw materials refined folding rate is as follows: mulberry silk: 75 ~ 80% mulberry silk, spun silk 95 ~ 98%, 90 ~ 95% silk noil yarn: 88 ~ 93% viscose, wool: 97% cotton, hemp: 95% (92%, bleaching, mercerizing) synthetic fiber: 99% (2) the shrinkage and dyeing, dyeing and finishing shrinkage ratio refers to the length of the fabric before and after dyeing dyeing and finishing shrinkage = grey silk weft density present the finished silk weft density = length of finished product present billet length square meters silk weight (g/m2) silk weight (g/m2) = silk weight per meter (g) present width (m). This is the fabric weight calculation method, I believe, will help you.
For the fabric weight of the unit is gram weight to calculate. Gram weight fabrics generally is grams, the weight of the square meters fabric gram weight is an important technical index for knitted fabrics, woollen cloth is usually the gram weight is an important technical indicators. Denim fabrics gram are generally use "ounces (OZ)" to express, namely the fabric weight on the number of ounces per square yard, such as 7 ounces, 12 OZ denim, etc; Among this, of course, also involves the effective width of the fabric, commonly used in inches or centimeters, common are 36 inches, 44 inches, 56-60 inches, etc., are called in the narrow, with wide, higher than 60 inches fabrics for the extra-width breadth, generally is often called wide cloth, in today's China, the fabric width can reach 360 cm wide. Width generally mark at the back of the density, such as: 3 mentioned in fabrics with width is expressed as: "45 x45/108 x58/60" "the width is 60 inches. Many aspects of calculating the fabric weight, will consider more comprehensive, the cost of booking, more accurate.
