What is a grey cloth

Interpretation of the grey cloth:

Natural cotton fabric for printing and dyeing.

Among them, C stands for pure carded cotton (raw material ratio), 30X30 refers to the yarn count in the warp and weft directions, and 68X68 refers to the density in the warp and weft directions. 1/1 refers to the structure of the grey fabric. 63" is the width of the grey fabric (the width of the latitude).

Common concept of grey cloth

1. warp, warp, warp density - fabric length direction; the yarn is called warp yarn; its number of yarns in 1 inch is dense (warp density);

2, weft, weft, weft density - fabric width direction; the yarn is called weft yarn, the number of yarns in 1 inch is weft density (weft density);

3. Density - used to indicate the number of yarns per unit length of the woven fabric, generally the number of yarns within 1 inch or 10 cm. The national standard specifies the number of yarns within 10 cm to indicate the density, but Textile companies are still accustomed to using the number of yarns within 1 inch to indicate density. As commonly seen, "45X45/108X58" means that the warp weft yarns are respectively 45 pieces, and the warp and weft density is 108, 58.

4, the width - the effective width of the fabric, generally used in inches or centimeters, common 36-inch, 44-inch, 56-60-inch, etc., respectively, called narrow, medium and wide, respectively, above 60 The inch fabric is extra wide, which is often called wide-width fabric. The width of today's extra-wide fabric can reach 360 cm. The width is generally marked behind the density, such as the fabric mentioned in 3, if the width is added, it means: "45X45/108X58/60"", that is, the width is 60 inches.

5, gram weight - the weight of the fabric is generally the weight of the square fabric weight, gram weight is an important technical index of knitted fabrics, woollen wool usually also refers to grams weight as an important technical indicator. The weight of denim fabric is generally expressed in "ounces (OZ)", that is, the number of ounces per square yard of fabric weight, such as 7 ounces, 12 ounces of denim, etc.;

6, yarn-dyed - Japan called "first dyed fabric", refers to the first method of dyeing yarn or filament, and then using color yarn for weaving, this fabric is called "dyed fabric", production color Weaving factories are generally called dyeing and weaving factories, such as denim, and most of the shirt fabrics are yarn-dyed fabrics.

Classification of grey cloth

1. Classified according to different processing methods

(1) Woven fabric: A fabric which is interlaced on a loom according to a certain rule by yarns which are arranged perpendicularly to each other, that is, two systems in the transverse direction and the longitudinal direction. There are denim brocade panels, silk yarn, etc.

(2) Knitted fabric: A fabric formed by weaving a loop into a yarn, which is divided into weft knitting and warp knitting. a weft knitted fabric is fed from the weft to the working needle of the knitting machine, so that the yarns are sequentially bent into a loop and are intertwined with each other. b Warp knitted fabrics are made by using one or several sets of yarns arranged in parallel, which are fed into all the working needles of the knitting machine in the warp direction and simultaneously formed into loops.

(3) Non-woven fabric: The loose fibers are bonded or stitched. At present, two methods of bonding and puncture are mainly used. This processing method can greatly simplify the process, reduce costs, improve labor productivity, and has a broad development prospect.

2. Classification according to the yarn materials constituting the fabric

(1) Pure woven fabric: The same kind of fiber is used as the raw material constituting the fabric, and there is a cotton fabric, a wool fabric, a polyester fabric, and the like.

(2) Blended fabric: The raw materials constituting the fabric are made of two or more kinds of different kinds of fibers, which are made by blending yarns, and have a blended fabric of polyester-viscose polynitrile polyester-cotton.

(3) Mixed fabric: The raw materials constituting the fabric are made of single yarns of two kinds of fibers, which are combined into a strand, and have low-elastic polyester filaments mixed with medium and long lengths, and also have polyester staple fibers and low elastics. Polyester filaments are mixed into a strand.

(4) Interwoven fabric: The raw materials of the two-direction system constituting the fabric are respectively made of different fiber yarns, antique satin interwoven with silk rayon, nylon and rayon interwoven Nifune.

3. According to whether the fabric materials are dyed or not

(1) White fabric: The raw material that has not been bleached and dyed is processed into a fabric, which is also called a raw fabric.

(2) Color fabric: The dyed raw material or fancy line is processed into a fabric, and the silk weave is also called a cooked fabric.

Pay attention to the difference between the grey cloth concept

1. Yarn dyeing and printing dyeing:

Yarn weaving - dyes the yarn and then weaves it with colored yarns, such as many shirt fabrics, denim, etc. The corresponding factory is called XXX dyeing and weaving factory, dyeing factory, etc.;

Printing and dyeing - the fabric after weaving is printed and dyed, such as a lot of printed fabrics, and the patterns are colorful. The corresponding factory is called XXX printing and dyeing factory, dyeing and finishing plant.

2, blended and interwoven

Blending - mixing two or more different fibers together in a spinning process and then weaving with a blended yarn;

Interlacing - fabrics woven from different types of yarns or filaments (bundles) when weaving.
