START WITH THE TEXTURE
1. YARN FINENESS
The representation of yarn fineness is generally divided into two categories: fixed length system and fixed weight system.
a. FIXED LENGTH SYSTEM
Expressed as the weight per unit length of the yarn at a fixed moisture regain. In the fixed length system, there are two types: the Tex (metric) system and the Denier
(imperial) system. Here, only the commonly used imperial system: Denier, which is generally used to indicate the fineness of pure chemical fiber filament and natural
filament. Denier is defined as the number of grams (g) of weight of 9000 meters of silk at a common moisture regain rate (about 8.5%) is the denier of the silk, which
is often represented by "D".
b. FIXED WEIGHT SYSTEM
Expressed as the length per unit weight of the yarn at a fixed moisture regain, in fixed weight systems. There are two kinds of metric (metric) and imperial (imperial).
Here only focuses on the commonly used imperial count, which is generally used to indicate the fineness of pure cotton yarn and polyester cotton yarn. The imperial
count is defined as: there are a number of 840 yards of yarn per pound at the common moisture regain rate (about 9.89%), which is often represented by "S". If the
pure cotton yarn weighs 1 pound at the common moisture recovery rate (about 9.89%), its length is 40×840 yards, that is, 33600 yards, then the cotton yarn is 40 pieces
which is often expressed as "40S". Generally speaking, the larger the number of yarn, the finer the yarn, the more difficult the spinning, the more processes, the higher
the equipment requirements, and the higher the quality requirements of cotton, (requiring the length of the cotton pile), the greater the price per ton of yarn. This is not
difficult to understand the difference in price between 40 pieces of fabric and 60 pieces of fabric.
2. DENSITY
Density - used to indicate the number of yarn roots per unit length of woven fabric, generally 1 inch or 10 centimeters of yarn roots, China's national standard stipulates
the use of 10 centimeters of yarn roots to represent the density, but textile enterprises are still used to use 1 inch of yarn roots to represent the density. It is divided into
warp density and weft density.
1. PRCISION - fabric length direction; This yarn is called refined yarn; The number of yarns arranged within 1 inch is precision (warp density);
2. WEFT DENSITY - fabric width direction; The directional yarn is called the weft yarn, and the number of yarns arranged within 1 inch is the weft density (weft density);
As usually seen in the hotel linen, "40X40/110X90" means that the warp and weft are 40, and the warp and weft density is 110 and 90.
3, WIDTH - the effective width of the fabric, generally used to be expressed in inches or centimeters, common 36 inches, 44 inches, 56-60 inches, etc., respectively called
narrow, medium and wide, more than 60 inches of fabric for wide, generally called wide cloth, today's China's extra wide fabric width can reach 360 centimeters. Width is
generally marked after the density, such as: 3 mentioned in the fabric if added width is expressed as: "40X40/110X90/72", that is, the width is 72 inches. (1 inch =2.54 cm).
4, GRAM WEIGHT - the gram weight of the fabric is generally the gram number of square meters of fabric weight. In the VISA tablecloth used in hotels, the gram weight is an
important technical index of the fabric.
5, YARN-dyed - Japan called "first dyed fabric", refers to the first yarn or filament dyed, and then the use of color yarn weaving process, this fabric is called "yarn-dyed fabric",
the production of yarn-dyed fabric factory is generally called dyeing and weaving factory. For example, VISA checkered tablecloths used in hotels and some fabrics that
make bed end towels are colored fabrics.
FABRIC CLASSIFICATION
1, ACCORDING TO DIFFERENT PROCESSING METHODS CLASSIFIED
(1) WOVEN FABRIC:
A fabric made up of yarns arranged vertically with each other, i.e. in two systems, transverse and longitudinal, interwoven on the loom according to certain rules. (Quilt
covers, sheets, tablecloths in the hotel linen are mostly woven fabrics).
(2) KNITTED FABRICS:
Fabric formed by weaving yarn into loops, divided into weft and warp knitting. (For example, our most common undershirt is knitted fabric, which is rarely used in hotel
linen, and a few outer curtain fabrics are knitted).
(3) NONWOVENS:
Loose fibers are bonded or stitched together. At present, two methods are mainly used: adhesion and puncture. (such as some laundry bags in the hotel linen, disposable
slippers are nonwovens).
CLASSIFIED ACCORDING TO THE YARN MATERIALS THAT MAKE UP THE FABRIC
(1) PURE TEXTILE:
The raw materials of the fabric are all made of the same fiber, cotton fabric, wool fabric, silk fabric, polyester fabric and so on. (Hotel linen quilt covers, sheets,
pillowcases and so on are basically pure cotton fabric, also known as cotton fabric).
(2) BLENDED FABRIC:
The raw materials of the fabric are made of two or more different kinds of fibers, which are blended into yarns, including polyester viscose, polyester nitrile, polyester
cotton and other blended fabrics. (Hotel linen in some quilt covers, sheets, pillowcases is polyester cotton and other blended fabrics).
(3) MIXED FABRIC:
The raw material of the fabric is made of single yarn of two kinds of fibers, which is made by merging into strands, such as low elastic polyester filament and medium
long yarn, and short polyester fiber and low elastic polyester filament. (A small number of curtains and decorative fabrics in the hotel are such fabrics).
(4) INTERWOVEN FABRIC:
The raw materials of the two directional systems of the fabric are respectively made of different fibers. (For example, most bed skirt fabrics and bed end towel fabrics
in hotel linen are interwoven fabrics)
3 ACCORDING TO THE COMPOSITION OF FABRIC RAW MATERIALS DYEING CLASSIFICATION
(1) WHITE FABRIC:
Unbleached raw materials are processed into fabrics, silk weaving is also called raw goods fabric.
(2) COLOR FABRIC:
the raw materials or fancy thread after bleaching and dyeing are processed into fabric, silk weaving is also known as cooked fabric.
4 ACCORDING TO THE STRUCTURE OF THE FABRIC IS DIVIDED INTO PLAIN TWILL SATIN AND JACQUARD ORGANIZATION
Also known as plain, twill, satin and jacquard fabric (fabric), the hotel quilt cover, pillowcase, bed sheet these three fabrics are very common, the most used. (Satin
strip fabric, back grid fabric, large jacquard fabric is a combination of one or more tissues, the specific explanation must be combined with the specific fabric)
Novel fabric classification
(1) Adhesive cloth:
It's made of two pieces of fabric that go back to back and are glued together. (Hotel linen is usually not used).
(2) flocking processing cloth:
Cloth covered with short, dense fiber fluff, velvet style, can be used as clothing and decoration material. (Some hotel curtains are such fabrics).
(3) Foam laminated fabric:
Foam is adhered to the woven fabric or knitted fabric as the base cloth, mostly used as a cold clothing material. (Usually not used in hotels).
(4) Coated fabric:
The base cloth of woven or knitted fabric is coated with polyvinyl chloride (PVC), neoprene rubber, etc., which has superior waterproof
function. (such as shower curtains in hotels).
PAY SPECIAL ATTENTION TO DISTINGUISH A FEW EASILY CONFUSED CONCEPTS:
1, YARN-DYED AND PRINTING DYEING:
a. yarn-weaving - dyeing the yarn, and then using colored yarn to weave cloth, such as many hotel plaid tablecloth, the corresponding factory called XXX dyeing and weaving
factory, yarn-weaving factory, etc.;
b. printing and dyeing - the fabric after weaving is printed and dyed, such as many and many printed fabrics with colorful patterns. The corresponding factory is called XXX
printing and dyeing factory, dyeing and finishing factory, etc.
2. BLENDING AND INTERWEAVING
a. Blending - the blending of two or more different fibers in the spinning process, and then weaving cloth with the blended yarn
b. Interlace - fabric made of different kinds of yarn or fiber filaments (bundles) when weaving.
