用优等品棉纱比用一等品棉纱，断裂强力要高10%，一等品比二等品也在10%左右。反映在成品布上的断裂强力也应该相差10%左右。但是做为酒店布草的面料没有必要用优等品棉纱，用二等品就足够了。棉纱标准要考虑各行各业的指标需求，只设定了优等品，一等品和二等品。没有设定三等品及不合格品的指标。只要达不到二等品的都可为三等品。

The breaking strength of top grade cotton yarn is 10% higher than that of first grade cotton yarn, and the breaking strength of first grade cotton yarn is about 10% higher than that of second grade cotton yarn. The breaking strength reflected on the finished cloth should also differ by about 10%. However, as the fabric of hotel linen, it is not necessary to use high-quality cotton yarn, and it is sufficient to use second-grade cotton yarn. The cotton yarn standard should take into account the indicator needs of all walks of life, and only set the first-class products, first-class products and second-class products. There are no indicators for third-class products and nonconforming products. As long as it does not reach the second class, it can be the third class.

原因一

Reason 1

家纺行业产值仅是服装行业的10%左右，纺织部棉纱标准主要是为服装行业制定的。服装行业高支纱对棉纱的品质要求比家纺高很多，棉纱成本占销售价的比重也较小。而家纺不同，产品附加值低，对棉纱成本很敏感。

The output value of the home textile industry is only about 10% of that of the clothing industry. The cotton yarn standard of the Ministry of Textiles is mainly formulated for the clothing industry. The high count yarn in the clothing industry has much higher requirements on the quality of cotton yarn than home textile, and the cost of cotton yarn accounts for a small proportion of the sales price. Unlike home textiles, the added value of products is low and is very sensitive to the cost of cotton yarn.

原因二

Reason 2

面料的质量除了和棉纱有关，还和织造密度和工艺相关。酒店布草的面料密度比家纺高，用二等品的棉纱织造，足以达到面料的国家标准。棉纱等级的不同主要受强力指标的制约。

In addition to cotton yarn, fabric quality is also related to weaving density and technology. The fabric density of hotel linen is higher than that of home textile. It is woven with second-class cotton yarn, which is enough to meet the national standard of fabric. The difference of cotton yarn grade is mainly restricted by the strength index.

面料的强力是影响酒店布草寿命的一个因素，俗话说，酒店布草不是用坏的，是洗坏的。所以影响酒店布草寿命主要是洗涤损害方面为主。如果追求用高一等级棉纱，酒店不会感到有明显的质量差异，但布草成本有2%-5%左右的提高。

The strength of the fabric is a factor that affects the service life of the hotel linen. As the saying goes, the hotel linen is not worn out, but washed out. Therefore, the main factor affecting the service life of hotel linen is washing damage. If we pursue to use a higher grade cotton yarn, the hotel will not feel any obvious quality difference, but the cost of linen will increase by about 2% - 5%.

所以说，棉纱相差一个等级对布草质量的影响不大。当然您对此还有什么问题不明白或者有什么需求，就可以随时来我们网站http://www.jnadx.com进行了解！
