Traditionally, woven fabrics are woven by shuttles driving the weft yarns back and forth through the warp yarns. In general, there is marked marginal tissue on both sides. Both grey and finished fabrics are flat. The knitted fabric is usually cylindrical, and after opening and closing, the finished product is flat.

Woven fabrics vary greatly. How to express different specifications? Yarn density is an important indicator.

Yarn count: In general, the contacts are British count. The specific definition is: British Yarn Count: There are several 840 yards of cotton yarn with a common weight of one pound, which is called the British Count. For example, if it contains 32840 yards, it's called 32 English counts, and so on. The higher the count, the finer the yarn.

At the same time, denier is also an indicator of fiber thickness. Unlike the British branch, the taller the fibers, the thicker the fibers. The specific definition is: fixed length of 9000 meters, weight 1g=1d, if the weight of 9000 meters long fiber is 70g, it is 70D. Converted to UK branch, it's 76s

Daniel is often used to describe finer fibers such as nylon, polyester, spandex, etc.

Density: The number of warp and weft threads per inch is called density. We have a densitometer. The dimensions in the box are 1 inch and the density is as much as we count.

For example: 20x16/128x60, that is, the warp is 20s and the weft is 16s. There are 128 warp threads and 68 weft threads per inch. This is just the basic fabric. In addition, there are many more complex fabrics. The representation of count density is correspondingly more complex.

Generally speaking, the density of non-elastic fabrics refers to the count density of grey fabrics, and the density of finished products will also change accordingly. Most non-stretch fabrics are available in greige widths of 47" or 63", while finished products are available in 44" or 58" widths, respectively. Taking 128x60/20x16 as an example, 47" x 128/44" = 136. Therefore, the finished density of this fabric should be around 136. The weft density before and after the finished product is basically unchanged, up to 1-2 up and down.

In the dyeing and finishing process of woven fabric grey fabric, after layer by layer treatment, there will be a certain weight reduction, so the number of yarns in the finished product is 1-2 less than that of grey fabric. Elastic cloth generally refers to the density of the finished product.

In addition to yarn, there is an important indicator to understand the organizational structure of woven fabrics. Generally speaking, the main points are as follows:

1. Plain weave, warp and weft are interwoven up and down, which is the basic weaving method. The thinner, lighter and thinner plain weave is called poplin and the thicker plain weave is called canvas.

2. There are three kinds of twill weave: 2/1, 3/1 and 2/2. Several ups and downs refer to the rise and fall of the warp. 3/1 means the warp floats over three wefts, sinks under one weft, and then floats over three wefts. This fabric is called yarn card or thread card.

3. Satin fabrics are generally 4/1 and 5/3. This is more complicated. As long as we understand the characteristics of the strong surface gloss of this fabric. There are more direct tributes.

4. Jacquard: It is done by a more complicated dobby loom. Generally speaking, dobby machines account for the majority, that is, dobby machines. Such as squares, wick strips, herringbone diagonal strips, satin strips, small jacquard strips, etc.

5. Velvet plants, mostly corduroy and velvet. The main feature of corduroy is that the weft density is much higher than the warp density. Because the weft yarn becomes a bunch of yarn after opening.
