The question of woven fabric specifications, the difference between knitted fabric and woven fabric?

1. The organizational structure of the fabric.

1) Knitted fabrics are generally bent into loops by yarns in order, and the loops are strung with each other to form fabrics, and the process of yarn forming loops can be carried out horizontally or longitudinally, transverse weaving is called weft knitting, and longitudinal weaving is called warp knitting.

2) Woven fabric is made up of two or more groups of perpendicular yarns, interwoven with warp and weft at a 90-degree angle, the longitudinal yarn is called warp, and the transverse yarn is called weft.

2. The basic unit of fabric organization.

1) The smallest unit of knitted fabric is the coil. The coil is composed of a coil trunk and an extension line in a spatial curve.

2) The smallest unit of the woven fabric is the weaving point, that is, each intersection point between the warp and weft.

3. Physical and mechanical.

1) The physical and mechanical properties of knitted fabrics are very good, including longitudinal density, horizontal density, square meter weight, elongation performance, elasticity, breaking strength, wear resistance, crimping, thickness, dispersion, shrinkage, coverage, and bulk density.

2) The physical and mechanical properties of woven fabrics only include the yarn density of warp and weft, cloth edge, front and back, forward and reverse hair direction, and fabric coverage.

60 * 58 - means that the woven fabric requires 21 yarn weaving, the warp density is: 60, and the weft density is: 58.

2. Human cotton 60 90 * 88 63 '- means that the composition of the woven fabric is human cotton, the warp density is: 90, the weft density is: 88, and the width is: 63 inches (about millimeters).

1.Nylon fine twill is commonly found in nylon spinning 2=2 twill, that is, the warp and weft are 2 in a trend cycle. It is commonly found at 330t.

2.Linings are commonly found in, polyester is more common, commonly found in polyester taffeta, fine lines are thick, rayon acetate lining. 210t is the sum of the specification density of the lining, for example, warp density 52 and weft density 30 times that is 210t.

And so on for the rest of the cloth.

3.Pearlescent cloth is the surface coating treatment of the fabric after calendering treatment, commonly found in, patent leather fabrics, pearlescent fabrics, etc., PU glue and pearlescent film are attached to the surface fiber of the fabric through high temperature and high pressure, which is more popular in recent years. Generally** is 10-15 yuan.

4.Taslon. Divided into. 184 196 228 Double warp and weft, polyester and nylon. T is a synonym for specification in filament fabrics.

"Diagonal" refers to the way in which the warp and weft yarns are staggered during the weaving process. Usually the fabric is vertical in warp and weft, while the warp and weft in the twill fabric are at a certain angle.

t" is a unit of yarn weaving.

The composition of the pearlescent cloth depends on what material the base fabric is, and the pearlescent is just a finishing method for this fabric, which is usually coated with a pearlescent glue.

Knitted fabric, also known as jersey, refers to the weft jersey fabric used to make underwear. The dry weight of square meters is generally 80-120g m2, the cloth surface is smooth, the texture is clear, the texture is fine, the feel is smooth, the longitudinal and transverse have good extensibility, and the transverse extensibility is larger than the longitudinal extensibility. It has good moisture absorption and air permeability, but it has dispersion and crimping, and sometimes the coil is skewed.

Common sweat cloths include bleached sweat cloth, extra white sweat cloth, fine bleached sweat cloth, singeing mercerized sweat cloth; According to the different post-dyeing and finishing treatment processes, there are plain jersey, printed jersey, and navy stripe jersey; According to the different raw materials used, there are blended jersey, silk jersey, acrylic jersey, polyester jersey, ramie jersey and so on. Knitted fabrics can be divided into warp knitting and weft knitting.

Featured knitted fabrics have soft texture, moisture absorption and breathability, excellent elasticity and elongation, and their producibility. Knitwear is comfortable, close to the body, free of tightness, and can fully reflect the curves of the human body.

Woven fabric: It is a cloth that interweaves the yarn vertically from the two directions of warp and weft, the longitudinal yarn is called warp, and the horizontal yarn is called weft. It is a woven fabric, a sheet textile formed by interweaving warp and weft yarns vertically with each other on a loom according to a certain law.

For example (plain weave, twill, satin, etc., all woven fabrics).

The knitting and weaving processes are not the same:

The woven fabric is woven from warp and weft yarns, and the yarn is wound around the shuttle, so it is called weaving. Common fabrics such as denim, cotton twill, plain weave, polyester, polyester cotton, nylon taslon, etc. Woven fabrics are mostly not elastic unless they are like stretch denim with elastic yarn.

Knitting is made of coils, divided into large circular knitting machine and small circular knitting machine and flat knitting machine, circular knitting machine common such as we often wear T-shirts and underwear, called jersey, as well as terry cloth, ribs, stripes.

Sweater thread is also knitting, is a flat knitting machine, processing sweater is the process of weaving, and self-woven sweater also belongs to knitting.

**The monk who came chanted the scriptures indiscriminately. It's a laughing death. There are more varieties of knitted fabrics. Sweat cloth is just one of the most common. Don't mislead others with nonsense if you don't understand!

The difference between knitted fabrics and woven fabrics.

Knitted fabrics and woven fabrics have their own unique characteristics due to their different methods of weaving, processing technology, fabric structure, fabric characteristics, and finished product use, so make some comparisons here.

a) Composition of fabric tissue:

a) Knitted fabric: It is the process of bending yarn into loops in sequence, and the loops are strung with each other to form fabrics, and the process of yarn forming loops can be carried out horizontally or longitudinally, transverse weaving is called weft knitting, and longitudinal weaving is called warp knitting.

b) Woven fabric: It is made of two or more groups of perpendicular yarns, interwoven with warp and weft at an angle of 90 degrees, the longitudinal yarn is called warp, and the transverse yarn is called weft.

2) Basic unit of fabric organization:

a) Knitted fabric: The coil is the smallest basic unit of the knitted fabric, and the coil is composed of a spatial curve of the coil trunk and the extension line.

b) Woven fabric: Each intersection point between the warp and weft yarns is called the weaving point and is the smallest basic unit of the woven fabric.

3) Fabric Tissue Characteristics:

a) Knitted fabrics: Because the coil is bent by yarn in space, and each coil is composed of a yarn, when the knitted fabric is subjected to external tension, such as longitudinal stretching, the bending of the coil changes, and the height of the coil also increases, while the width of the coil decreases, such as the tension is transversely stretched, the situation is the opposite, the height and width of the coil can obviously be converted to each other under different tension conditions, so the extensibility of the knitted fabric is large.

b) Woven fabric: because the warp and weft intertwined places are bent, and the fold is bent in the direction perpendicular to the plane of the fabric, the degree of bending is related to the mutual tension between the warp and weft yarns, as well as the stiffness of the yarn, when the woven fabric is subjected to external tension, such as longitudinal stretching, the tension of the warp increases, and the bending of the weft increases, such as longitudinal stretching, until the warp is completely straightened, and the fabric is transversely contracted. When the woven fabric is stretched transversely by external tension, the tension of the weft yarn increases, and the bending decreases, while the warp bending increases, such as the transverse stretching does not stop until the weft yarn is completely straightened, and the fabric shrinks longitudinally.

Warp and weft yarns, on the other hand, do not change, unlike knitted fabrics.

4) Characteristics of the fabric tissue:

a) Knitted fabrics: It can be extended in all directions and has good elasticity, because knitted fabrics are formed by hole-like loops, which have greater air permeability and soft feel.

b) Woven fabric: Because the warp and weft of the shuttle fabric have little relationship with the contraction, and there is no conversion, the fabric is generally relatively tight and stiff.

5) Physical and mechanical properties of fabric tissue:

a) Knitted fabrics: the physical and mechanical properties of fabrics, including longitudinal density, transverse density, square meter weight, elongation performance, elasticity, breaking strength, abrasion resistance, crimping, thickness, dispersion, shrinkage, coverage, and bulk density.

b) Woven fabric: the physical and mechanical properties of the woven fabric, including the yarn density of warp and weft, cloth edge, front and back, forward and reverse hair direction, and fabric coverage.
