What is the difference between non woven fabrics and woven fabrics? Difference Between Nonwovens and

The soft and hard feel of the cloth is different, and the road pattern is also different.

2008-7-28 06:51 |Questioner: The Confused Light 1. 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, cloth structure, fabric characteristics, and finished product use.

1) Composition of fabric structure: (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. (ii) Basic unit of fabric organization:

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

Each point of intersection between the warp and weft yarns is called the weaving point and is the smallest basic unit of the woven fabric. (3) Fabric structure characteristics: (a) Knitted fabrics:

Because the coil is made of yarn bent 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 are intertwined with some bending, 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, and 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 decreases, while 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. (iv) Characteristics of fabric weave:

a) Knitted fabrics: It can be extended in all directions and has good elasticity, because knitted fabrics are formed by perforated loops, which have greater breathability and soft feel. (b) Woven fabrics:

Because the warp and weft of the woven fabric have little relationship with the contraction, and do not change, the fabric is generally relatively tight and stiff. (v) Physical and mechanical properties of the fabric structure: (a) Knitted fabrics:

The physical and mechanical properties of fabrics, including longitudinal density, transverse density, square meter weight, elongation properties, elasticity, breaking strength, abrasion resistance, crimping, thickness, dispersion, shrinkage, coverage, and bulk density. (b) Woven fabrics: the physical and mechanical properties of woven fabrics, including the yarn density of warp and weft, cloth edges, front and back sides, forward and reverse hair directions, and fabric coverage.

Woven fabrics are silk, cotton, linen, woolen fabric, chemical fiber, etc., and the advantages and disadvantages are as follows:

1. Silk. Advantages: comfortable to wear, smooth surface, good absorption and dehumidification, good heat dissipation performance, sound absorption, dust absorption, flame retardant, ultraviolet resistance, health care.

Disadvantages: easy to wrinkle, easy to absorb the body, not strong enough, fade quickly, can not keep warm.

2. Cotton cloth. Advantages: Easy to keep warm, soft and close, moisture absorption, breathability.

Disadvantages: easy to shrink, easy to wrinkle, not very structured and beautiful in appearance, and must be ironed from time to time when wearing.

3. Linen. Advantages: high strength, moisture absorption, heat conductivity, air permeability.

Disadvantages: Not very comfortable to wear, rough appearance, stiff.

4. Woolen wool. Advantages: wrinkle-resistant and wear-resistant, soft to the touch, elegantly structured, elastic, and warm.

Disadvantages: It is difficult to wash and is not suitable for making summer clothes.

5. Chemical fiber. Pros: Bright colors, soft texture, draped and structured, smooth and comfortable.

Disadvantages: poor wear resistance, heat resistance, moisture absorption, air permeability, easy to deform when heated, and easy to generate static electricity.

In fact, there is no difference between non-woven fabrics and non-woven fabrics, they are just two different names. It is to specify the direction or random arrangement of some fibers, and then through various methods such as interweaving, they are combined with each other to make a thin piece of cloth. In general, it is customary to use Cantonese.

Friends will say that the weaver is buried in the year, and the standard Mandarin name is non-woven fabric. The use of non-woven fabrics is also relatively extensive, and it has also been widely used in the medical field on a large scale.

Summary. Polyester-cotton refers to polyester-cotton blended fabrics, which are made of polyester as the main component, and polyester-cotton blended fabrics are textiles woven with polyester as the main ingredient and 65%-67% polyester and 33%-35% cotton blended yarns. It not only highlights the style of polyester but also the advantages of cotton fabric, has good elasticity and abrasion resistance in dry and wet conditions, stable size, small shrinkage, and has the characteristics of straightness, not easy to wrinkle, easy to wash and quick drying.

These fabrics have the commonality of woven fabrics.

The polyester fiber in polyester cotton is a hydrophobic fiber, which has a strong affinity for oil stains, is easy to adsorb oil stains, and is easy to generate static electricity and adsorb dust during wearing, which is difficult to wash, and can not be ironed at high temperature and soaked in boiling water. Most polyester fabrics are woven fabrics.

Most polyester fabrics belong to Hongzhi woven fabrics.

Polyester cotton is a mixture of polyester and cotton, and the feel is not as comfortable as cotton. Wear and not as good as cotton to absorb sweat. Polyester is the number one variety with the highest yield among synthetic fibers.

Polyester is a chemical fiber fabric that does not easily wick away perspiration. It feels like a thorn and pull, it is easy to ignite static electricity, and it looks bright obliquely, which is somewhat special compared to other reed-headed woven fabrics.

Woven fabric is a loom in the form of a shuttle, the yarn through the warp and weft staggered and composition, its organization generally has plain, twill and satin three categories and their variations. This type of fabric is strong, crisp and not easy to change the shape due to the interlacing of warp and weft weaves. In terms of composition, it is classified into cotton fabrics, silk fabrics, wool fabrics, hemp fabrics, chemical fiber fabrics and their blended and interwoven fabrics.

The use of woven fabrics in clothing is a world leader in terms of both the variety of liquid plums and the number of production. Widely used in a variety of high-end clothing, woven clothing because of its style, technology, style and other differences in the processing process and technological means.

Polyester and nonwovens differ significantly in several ways:

1.Material: Polyester is a polyester fiber, while non-woven fabric is a non-woven fabric formed by a variety of fibers through air flow or mechanical webting.

2.Preparation: Polyester is prepared by esterification or transesterification and polycondensation reaction, while non-woven fabrics are formed by fibers through air flow or mechanical webting.

3.Performance characteristics: Polyester has high strength and impact strength, while non-woven fabric has the advantages of light weight and easy shaping. In addition, the wet strength of polyester is basically the same as the dry strength, while the cutting and sewing of non-woven fabrics are very convenient.

4.Applicable fields: Polyester is mainly used in clothing, home furnishings, bags, sports equipment and other fields, while non-woven fabrics are widely used in medical, hygiene, daily necessities, industry and other fields.

To sum up, polyester and non-woven fabrics are different in terms of material, preparation method, performance characteristics and applicable fields.

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.
