For an example of a knitted fabric, we use a very velvet fabric sold on Taobao to analyze it. The usual velvet fabric is weft-knitted weaving. In China, the strong weaving base for producing such fabrics is Changshu, Jiangsu. . Velvet fabrics are usually measured in kilograms during weaving production and trading. Then, when purchasing fabrics, in order to calculate the price per meter, the buyer must convert the kilograms into meters. Many newcomers also often ask for the price per meter. Sometimes, the price of rice is wrong, then inquiries. In the price process, it is recommended that you use kilograms for inquiry and then convert yourself. In fact, the formula for conversion is very simple. First, you need to understand two keywords:
1, fabric weight, usually square gram weight, gram weight usually represents the thickness and density of the fabric, then how do you know how many grams of fabric you need? First of all, you need to find the ideal swatch, use a special square knife weight disc mold to engrave a piece of fabric, and put the weight of the electrons weighing gram weight. If the fabric is not enough for the disc mold, we can cut a piece of fabric more than 2 cm, need to cut the square, then measure the length and width, and put this small fabric into the weighing weight. The electrons weighed the weight and recorded the data. Finally, the formula is: gram weight / length X width.
2, fabric door width, the width of the door is generally the lowest and highest size that can be achieved according to the fabric production process. For example, the width of the velvet fabric can be between 150-250cm, so in order to save costs, the garment cutting layout can calculate the most reasonable width requirements, such as the 220cm width. Then let's calculate the kilogram conversion to the meter length.
How do knit fabrics calculate how many meters per kilogram? We can calculate according to this formula: 1000 / square gram / meter width = length per kilometer. For example: there is a velvet with a weight of 250 grams. The fabric fabric purchaser needs 2 meters of velvet fabric according to the clothing layout. Then, we can calculate by the above formula: 1000/250 g / 2 m = 2 Meter (per kilogram). Then, the next price conversion is easy.
