Basic concept of hotel linen fabric-1

The quality of hotel linen is an important factor for customers to have a good or bad impression of the hotel, so the choice of hotel linen fabrics is very important. Before purchasing linen, the hotel will customize the list and specifications of what it needs, such as yarn count, density, width, weight, etc., and there are many types of fabrics. If you dont know the linen fabrics, it will be easier to purchase difficulty.

common concept

1. Yarn fineness

The representation methods of yarn fineness are generally divided into two categories: fixed length system and fixed weight system.

a. Fixed length system

It is expressed by the weight per unit length of the yarn at the specified moisture regain. In the fixed-length system, there are two types of Tex system (metric system) and Denier system (imperial system). Here we only introduce Commonly used imperial system: Denier (Denier), generally used to indicate the fineness of purified fiber filaments and natural filaments. The definition of Denier (Denier) is: the weight of a 9000-meter-long filament at a given moisture regain (about 8.5%) The number of grams (g) is the denier of the silk, which is often expressed by "D".

b. Customized system

The line is represented by the length of the unit weight at the time of the public moisture regain. In the fixed weight system, there are two types of metric counts (metric system) and imperial counts (imperial system). Here only the commonly used imperial counts are introduced, which are generally used to express The fineness of pure cotton yarn and polyester-cotton yarn. The definition of count is: there are a number of 840 yards per pound of yarn at a given moisture regain (about 9.89%), which is a number of counts, which is often expressed by "S". Cotton yarn weighs 1 pound at the established moisture regain (about 9.89%), and its length is 40840 yards or 33,600 yards, so the cotton yarn is 40, which is often represented by "40S", which is often referred to as hotel linen 40s fabric . Generally speaking, the larger the yarn count, the finer the yarn, the more difficult it is to spin, the more processes, the higher the requirements for equipment, and the higher the requirements for cotton quality. The higher the price. (The Athens company chooses Xinjiang long-staple cotton), it is not difficult to understand that there is a difference in the price of 40-count fabrics and 60-count fabrics.

2. Density

Indicates the number of yarns per unit length of woven fabrics, generally the number of yarns within 1 inch or 10 centimeters. my countrys national standards stipulate that the number of yarns within 10 centimeters is used to indicate density, but textile companies still use 1 inch

The number of inner yarns represents the density.

Among them, it is divided into warp density and weft density

a.The length direction of the fabric; the yarn in this direction is called the warp yarn; the number of yarns arranged within 1 inch is the warp density (warp yarn density);

b.Width direction of the fabric; the yarns in this direction are called weft yarns, and the number of yarns arranged within 1 inch is the weft density (weft yarn density); for example, the "40X40/110X90" usually seen in hotel linen means warp yarns The weft yarns are 40 counts respectively, and the warp and weft densities are 110 and 90.

3. Width

The effective width of the fabric is generally expressed in inches or centimeters. The common ones are 36 inches, 44 inches, 56-60 inches, etc., which are called narrow width, medium width and wide width, and fabrics higher than 60 inches are wide width. , Generally often called wide-width fabrics, the width of extra-wide fabrics in my country today can reach 360 cm.

The general mark is behind the density, such as: if the fabric mentioned in 3 is added with the width, it will be expressed as: "40X40/110X90/72"", that is, the width is 72 inches. (1 inch=2.54 cm)

4. Weight

The weight of the fabric is generally the number of grams of the weight of the square meter fabric. In the VISA tablecloth used in the hotel, the weight is an important technical indicator of the fabric.

5. Yarn-dyed

This term is called "first-dyed fabric", which refers to the process of dyeing yarn or filament first, and then using colored yarn to weave. This kind of fabric is called "dyed fabric", and factories producing yarn-dyed fabric are generally called For dyeing and weaving factories. For example, VISA plaid tablecloths used in hotels and some fabrics for making bed scarves are dyed fabrics.
