布草質量好壞首先從面料來甄別，而面料的優勢主要以經緯密、平方米克重、強力/撕拉力/單紗力、毛羽、色牢度、縮水率、緯斜為主。紅金頂與您分享關于選擇酒店布草面料幾個小知識。

The quality of linen is first judged by the fabric, and the advantages of the fabric mainly include warp and weft density, square meter weight, strength/tear/single yarn strength, fuzziness, color fastness, shrinkage rate, and weft skewness. Hongjinding shares with you a few tips on choosing hotel linen fabrics.

一、經緯密度

1、 Latitude and longitude density

1.指一英寸單位內，棉紗的總根數

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

2.工藝書寫格式：經向*緯向列如：110*90

2. Process writing format: warp * weft columns, such as 110 * 90

3.通常面料工藝中標識的是胚布的經緯密度，漂染過程會使面料經緯面度發生變化，經向因伸長而減少2-4%，緯向因縮進而增加5%；面料經緯密度的總數不變，或略增加。

3. Usually, the warp and weft density of the raw fabric is marked in the fabric process. The dyeing process will cause changes in the warp and weft flatness 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 warp and weft density of the fabric remains unchanged or slightly increases.

4.成品書寫格式：T200、T250、T300

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

5.國家對經緯密度的標準，是用平方米克重來檢驗。

5. The national standard for longitude and latitude density is to test it in square meter grams.

紅金頂嚴格按照國家標準對布草的經緯度織造工藝進行把控。

Hongjinding strictly controls the warp and weft weaving process of the fabric according to national standards.

二、面料的強力

2、 The strength of the fabric

1.面料強力分為撕拉強力和單拉強力

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

2.撕拉強力是發映面料在出現小面積破損時，破損部位擴張的阻力

2. Tear strength refers to the resistance of the damaged area of the fabric to expand when there is a small area of damage

3.單拉強力是指面料在單位平方米內，能承受的拉力

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

4.強力的高低主要與棉紗質量（單紗強力）和漂染工藝有關

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

5.通常好的面料其韌性就比較好，比如紅金頂品牌制作的酒店布草面料成品。

5. Generally, good fabrics have better toughness, such as hotel linen fabrics produced by the Red Gold Top brand.

三、平方米克重

3、 Square meter weight

1.能夠客觀的反映出面料的用紗量（即成本）

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

2.防止用細紗支來代用粗紗支

2. Prevent using fine yarn support instead of coarse yarn support

3.測量的方法是，用圓盤取樣器，劃取100C㎡的面料進行稱重

3. The measurement method is to use a disc sampler to draw a 100C ㎡ fabric and weigh it

4.測驗結果對照面料的標準值，常溫下40S全棉T250，標準值是：135g/C㎡

4. The test results are compared to the standard value of the fabric, which is 135g/C ㎡ for 40S cotton T250 at room temperature

例如紅金頂枕芯的面料平方比克重計算公式為2500-3000g/m2。

For example, the formula for calculating the square specific weight of the fabric for the red gold top pillow core is 2500-3000g/m2.

四、縮水率

4、 Shrinkage rate

1.全棉縮水率一般為：經向5%，緯向5%。

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

2.滌棉縮水率一般為：經向2.5%，緯向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.做預縮的面料可適當降低縮水率，預縮后全棉經、緯紗縮水率為3.5%

3. For pre shrunk fabrics, the shrinkage rate can be appropriately reduced. After pre shrinking, the shrinkage rate of all cotton warp and weft yarns is 3.5%

紅金頂酒店布草溫馨提示：您在選購棉質酒店布草尺寸時要考慮棉質布草會有縮水率，詳情可咨詢紅金頂專業布草選購顧問。

Reminder: When choosing the size of cotton hotel linen, you should consider the shrinkage rate of cotton linen. For more details, please consult a professional linen selection consultant at Hongjinding.

五、面料緯斜

5、 Fabric weft diagonal

1.緯斜的計算方法：緯斜幅度/整個門幅

1. Calculation method for latitude deviation: latitude deviation amplitude/entire door width

2.緯斜主要影響產品的平整度效果

2. The skewness of the weft mainly affects the flatness effect of the product

3.目前國內沒有一家染廠可以做100%不緯紋斜

Currently, there is no dyeing factory in China that can produce 100% non weft diagonal weave

六、面料毛羽

6、 Fabric fuzziness

1.毛羽是由于短纖維太多造成的布面現象

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

2.造成的后果：脫毛率高、起球

2. Consequences: High hair removal rate and pilling

紅金頂采用的原料是源自公司自有新疆棉基地的優選新疆棉，長絨棉，從原料就對顧客承諾保障紅金頂生產的酒店布草經久耐用。

The raw materials used by Hongjinding are selected Xinjiang cotton and long staple cotton from the company's own Xinjiang cotton base. From the raw materials, we promise to ensure that the hotel linen produced by Hongjinding is durable and long-lasting.

七、色牢度

7、 Color fastness

色牢度分為：水洗牢度、粘色牢度（指有色產品）

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