　　織物的克重一般是平方米織物重量的克數，克重是針織物的重要技術指標，克重通常也是粗花呢的重要技術指標。那么為什么面料的重量不夠呢?山東園服定做公司告訴您:
　　The weight per gram of the fabric is generally the weight per gram of the square meter of the fabric. The weight per gram is an important technical index of the knitted fabric, and the weight per gram is also an important technical index of the Tweed. Then why is the weight of the fabric insufficient? Qinchuan garden service company tells you:
　　1. 織物重量:
　　1. Fabric weight:
　　每克重量是指紡織品在標準計量單位中的重量。
　　Weight per gram refers to the weight of textiles in standard units of measurement.
　　例如，1平方米針織物的克重為200克，表示為:200克/平方米等。
　　For example, the weight of 1 square meter knitted fabric is 200 grams, which is expressed as: 200 grams / square meter, etc.
　　單位-紡織品的“克”是重量單位。
　　Unit - the "gram" of a textile is the unit of weight.
　　第二，影響體重不足的因素
　　Second, factors affecting underweight
　　1. 購買原紗時，紗線很細;例如，40支紗線實際上只有41支紗線。
　　1. When purchasing the original yarn, the yarn is very thin; for example, 40 yarns actually only have 41 yarns.
　　2. 回潮率不足。印染織物干燥后會失去大量水分，織物規格是指標準水分回收率下的克重。因此，當天氣干燥，干布不能恢復其全部重量，克將不夠，特別是天然纖維，如棉花，亞麻，絲綢和羊毛，這將有很大的偏差。
　　2. The return tide rate is insufficient. Dyeing and printing fabrics will lose a lot of moisture after drying. Fabric specification refers to the weight of gram under the standard moisture recovery rate. Therefore, when the weather is dry and the dry cloth cannot recover its full weight, gram will not be enough, especially for natural fibers such as cotton, linen, silk and wool, which will have a great deviation.
　　3.原紗在織造過程中磨損嚴重，毛羽脫落過多，導致紗線變薄，克重下降。
　　3. In the process of weaving, the original yarn is seriously worn and the hairiness falls off too much, which causes the yarn to become thinner and the weight of gram to drop.

　　4. 在染色過程中重新染色會導致紗線大量損耗和變薄。
　　4. In the process of dyeing, re dyeing will cause a lot of yarn loss and thinning.
　　5. 在燒毛過程中，過度燒毛會導致布料表面過度干燥，退漿時紗線損壞會導致變薄。
　　5. In the process of singeing, excessive singeing will lead to excessive drying of cloth surface, and yarn damage will lead to thinning when desizing.
　　6. 燒堿在絲光過程中損壞紗線。
　　6. Caustic soda damages the yarn during mercerizing.
　　7. 布蓋因刮擦和拋光而損壞。
　　7. The cloth cover is damaged by scraping and polishing.
　　8. 最后，密度不符合工藝要求。如果不按規格生產，緯紗密度和經紗密度是不夠的。
　　8. Finally, the density does not meet the process requirements. If not produced according to specifications, weft density and warp density are not enough.
　　這是花園服裝面料克重不足的原因介紹。應該理解的是，牛仔布的克重一般用“OZ”來表示，即每平方碼布料的盎司數，如7盎司、12盎司等。
　　This is the reason for the lack of weight of garden clothing fabric. It should be understood that the gram weight of denim is generally expressed by "Oz", that is, the number of ounces per square yard of cloth, such as 7 ounces, 12 ounces, etc.
