1. Fiber fabrics

(1) Fiber fabric

基本上都是由纖維經(jīng)過紡織后成紗，然后再經(jīng)過紡織后成面料。纖維的概念是天然或人工合成的，長(zhǎng)度比直徑大千倍以上而且有一定的柔韌性的細(xì)絲狀物質(zhì)。

2. Classification of fibers

(2)natural fiber

Natural fibers are fibers obtained directly from nature and generally come in two forms:

1)Plant fibers such as: cotton, linen, etc.

2)Animal fibers such as wool, silk, etc.

3. Synthetic fibers

Synthetic fibers are fibers obtained by chemical treatment and injection spinning, such as acrylic, polyester, nylon, etc. Identification of fiber quality The thickness and length of fibers are important factors that determine the feel of fabrics. Coarse fiber fabrics have a hard, stiff and thick feel and are resistant to compression. The shorter the fibers, the rougher the fabric and the easier it is to pill. The fine fibers give the cloth a soft, thin feel. The longer the fiber, the smoother and smoother the yarn, the less pilling.

2. Yarn count????

1. Yarn count is the basic unit of finished fabric. The number of yarn count is inversely proportional to its thickness. The larger the number, the finer it is, and the corresponding quality requirements for the raw material (cotton) are also higher.

2. The fineness of the yarn indicates that the yarn is generally represented by its fineness. Refers to the number of 840 yards (1 yards = 0.941 meters) long of a pound (454 grams) of cotton yarn when the moisture regain is specified, that is, a few British yarns, which can be simply read as "a few yarns", and the unit is " S" means.

3. What is the official return rate? Definition formula: moisture regain = (wet weight - dry weight)/dry weight * 100%; national standard public moisture regain: cotton yarn 8.5%, cotton 8%, polyester-cotton gauze 3.06%, cloth 100% 4.2 out of 10.

4. Identify the fineness of the yarn. The larger the number in front of S, the finer the yarn, and the lighter, thinner and softer the woven fabric will be. The smaller the number, the thicker the yarn, and the heavier, thicker, and rougher the woven fabric. For example, the yarn counts of bedding are generally divided into 21, 30, 40 according to their thickness, and there are also 80 which are relatively rare.??????

5. The concept of density, density is the number of yarns per unit length, generally the number of yarns within 1 inch or 10 cm. my country's national standard stipulates that the number of yarns within 10 cm is used to indicate density, but it is still Some textile companies are still used to expressing the density by the number of yarns within 1 inch.

3. Classification of Density

The length direction of the warp density fabric; the direction yarn is called the warp yarn; the number of yarns arranged within 1 inch is the warp density and the weft density, and the width direction of the fabric; the direction yarn is called the weft yarn, and the number of yarns within 1 inch is The number of arranged roots is the weft density (weft density), the warp density and the weft density can be the same or different.

Fourth, the classification of hotel fabrics woven fabrics:?

It is a fabric formed by interweaving yarns of two systems, namely horizontal and vertical, arranged perpendicular to each other on a loom according to certain rules. For example, the quilt covers, bed sheets and tablecloths in the hotel linen are mostly woven fabrics. The following are divided into four types of textiles:

1. Non-woven fabric: The loose fibers are bonded or sewn together. At present, two methods of bonding and puncturing are mainly used. For example, some laundry bags in the hotel linen and disposable slippers are all non-woven fabrics.?????

2. Pure textile fabrics: The raw materials that make up the fabrics all use the same fiber, including cotton fabrics, wool fabrics, silk fabrics, polyester fabrics, etc. For example, the quilt covers, bed sheets, pillowcases, etc. in the hotel linen are basically pure cotton fabrics, also called cotton fabrics.????????

3. Blended fabrics: The raw materials of fabrics are made of two or more different types of fibers, which are blended into yarns. For example, some quilt covers, bed sheets and pillowcases in the hotel linen are blended fabrics such as polyester and cotton.???????????

4. Interwoven fabric: The raw materials constituting the two direction systems of the fabric are made of different fiber yarns. ?For example, most of the bed skirt fabrics and bed end pad fabrics in the hotel linen are interwoven fabrics.
