酒店布草的质量是顾客对酒店印象评价的重要因素，因此酒店布草的选择很重要。布草质量好坏的鉴别主要从面料来选，而面料的优势主要以：经纬密度、平方米克重、强力/撕拉力/单纱力、毛羽、色牢度、缩水率、纬斜为主，下面分享如何鉴别酒店布草的好坏：

　　The quality of hotel linens is an important factor in customers' impression and evaluation of the hotel, so the choice of hotel linens is crucial. The identification of the quality of linen is mainly based on the fabric, and the advantages of the fabric mainly include: warp and weft density, square meter weight, strength/tear force/single yarn force, feather, color fastness, shrinkage rate, and weft inclination. Below, we will share how to identify the quality of hotel linen:

　　第一、经纬密度

　　Firstly, latitude and longitude density

　　1、指一英寸单位内，棉纱的总根数

　　1. Refers to the total number of cotton yarns within one inch unit

　　2、工艺书写格式：经向*纬向列如：110*90

　　2. Craft writing format: meridional * latitudinal column, such as 110 * 90

　　3、通常面料工艺中标识的是胚布的经纬密度，漂染过程会使面料经纬面度发生变化，经向因伸长而减少2-4%，纬向因缩进而增加5%；面料经纬密度的总数不变，或略增加。

　　3. The warp and weft density of the embryo fabric is usually identified in the fabric process. The dyeing process will cause changes in the warp and weft of the fabric, with a decrease of 2-4% in the warp direction due to elongation and an increase of 5% in the weft direction due to indentation; The total number of warp and weft densities of the fabric remains unchanged or slightly increases.

　　4、成品书写格式：T200、T250、T300

　　4. Finished product writing format: T200, T250, T300

　　5、国家对经纬密度的标准，是用平方米克重来检验。

　　5. The national standard for latitude and longitude density is to use square meters for testing.

　　第二、面料的强力

　　Secondly, the strength of the fabric

　　1、面料强力分为撕拉强力和单拉强力

　　1. Fabric strength is divided into tearing strength and single pulling strength

　　2、撕拉强力是发映面料在出现小面积破损时，破损部位扩张的阻力

　　2. Tear strength is the resistance to the expansion of the damaged area when a fabric is subjected to minor damage

　　3、单拉强力是指面料在单位平方米内，能承受的拉力

　　3. Single pull strength refers to the tensile force that a fabric can withstand per unit square meter

　　4、强力的高低主要与棉纱质量（单纱强力）和漂染工艺有关

　　4. The strength is mainly related to the quality of cotton yarn (single yarn strength) and dyeing process

　　第三、平方米克重

　　Thirdly, the square meter weight

　　1、能够客观的反映出面料的用纱量（即成本）

　　1. Can objectively reflect the amount of yarn used in the fabric (i.e. cost)

　　2、防止用细纱支来代用粗纱支

　　2. Prevent using fine yarn as a substitute for coarse yarn

　　3、测量的方法是，用圆盘取样器，划取100C㎡的面料进行称重

　　3. The measurement method is to use a disc sampler to draw a fabric of 100 square meters and weigh it

　　4、测验结果对照面料的标准值，常温下40S全棉T250，标准值是：135g/C㎡

　　4. The test results are compared with the standard value of the fabric. At room temperature, the standard value of 40S full cotton T250 is 135g/C ㎡

　　第四、缩水率

　　Fourth, shrinkage rate

　　1、全棉缩水率一般为：经向5%，纬向5%。

　　1. The shrinkage rate of cotton is generally 5% in the warp direction and 5% in the weft direction.

　　2、涤棉缩水率一般为：经向2.5%，纬向2.5%

　　2. The shrinkage rate of polyester cotton is generally 2.5% in the warp direction and 2.5% in the weft direction

　　3、做预缩的面料可适当降低缩水率，预缩后全棉经、纬纱缩水率为3.5%

　　3. Pre shrunk fabrics can reduce the shrinkage rate appropriately. After pre shrinking, the shrinkage rate of cotton warp and weft yarns is 3.5%

　　第五、面料纬斜

　　Fifth, fabric warp angle

　　1、纬斜的计算方法：纬斜幅度/整个门幅

　　1. The calculation method of latitude inclination: latitude inclination amplitude/entire gate amplitude

　　2、纬斜主要影响产品的平整度效果

　　2. The warp angle mainly affects the flatness effect of the product

　　3、目前国内没有一家染厂可以做100%不纬纹斜

　　3. At present, there is no dyeing factory in China that can produce 100% non warp diagonal lines

　　第六、面料毛羽

　　Sixth, Fabric Feather

　　1、毛羽是由于短纤维太多造成的布面现象

　　1. Feather is a fabric phenomenon caused by too many short fibers

　　2、按纤维长度分为：长绒棉（825px）、埃及棉、新疆棉，棉美国

　　2. Divided by fiber length: long staple cotton (825px), Egyptian cotton, Xinjiang cotton, cotton from the United States

　　3、造成的后果：脱毛率高、起球

　　3. Consequences: high hair removal rate, pilling

　　第七、色牢度

　　Seventh, color fastness

　　色牢度分为：水洗牢度、粘色牢度（指有色产品）。

　　Color fastness is divided into washing fastness and adhesion fastness (referring to colored products).
