What is the difference between woven and knitted yarn?
There are two main methods of knitting, knitting and weaving. Knitting is to weave in the way of coil over coil, the fabric is characterized by the fact that you can not see the fabric warp and weft are intersected vertically, but one by one, and then the feel of the knitted fabric is soft and drapey; woven refers to the fabric warp and weft (that is, vertical and horizontal) after vertical interweaving and formed; machine woven is divided into shuttle and shuttleless weaving, the difference is that in the weaving with or without the shuttle The difference is whether the weaving is done with or without the shuttle.
What is weaving and knitting
The use of knitting needles to a variety of raw materials and varieties of yarn to form a loop, and then connected by the string set into the knitted fabric process. Knitted fabrics have a soft texture, good wrinkle resistance and air permeability, and have greater stretch and elasticity, knitted products can be used in agriculture and industry, as well as in the fields of health care and national defense, in addition to for use and decoration. Knitting is divided into two categories: manual knitting and machine knitting. Hand-knitting uses stick needles, which has a long history, exquisite skills and flexible flower shapes, and has been widely circulated and developed in folklore.
The process of forming woven fabrics with yarns for warp and weft according to various fabric structures. Usually includes the warp yarn into the weaving axis, the weft yarn into the twist (or tube) of the weaving preparation, weaving and weaving blank finishing three parts. Weaving is an important part of the textile industry production, according to the type of raw materials used can be divided into cotton, wool, silk and linen weaving, its products are collectively known as woven fabrics. The variety of woven fabrics and with a wide range (see textiles), according to the different requirements for the use of the selection of suitable yarn materials and suitable fabric organization.
The difference between woven and knitted
1, the fabric organization is different. Woven through the control of weft yarn through the warp yarn law of different, can form different fabric pattern and structure. Knitted fabrics also have the corresponding organizational structure, including the basic organization: flat needle organization, ribbing organization, and double reverse organization.
2, change the organization is different. Woven is formed by the above three basic tissue changes, joint. Knitting in addition to the three basic organizational changes, there are flat needle organization, ribbing organization as its basic changes.
3, the basic unit of fabric organization is different. Knitted fabric coil is the basic unit of knitted fabric, and the coil by the circle stem and extension line is a space curve composed of. Woven fabric warp and weft yarn between each intersection point is called tissue point, is the basic unit of woven fabric.
4, complex Chengdu different. Weaving has two organizations (more woven into thick pile, cotton pile blanket, etc.), pile organization (such as corduroy fabric), towel organization (towel fabric), double layer organization (towel fabric) and leno organization. And knitting and double reverse organization. In general, the complexity of Chengdu than woven.
5, the characteristics and uses are different. Woven fabrics are suitable for a variety of printing and dyeing finishing methods, in general, printing and jacquard pattern than knitted fabrics, knitting and felt fabrics more fine. Knitted fabrics in changing the structure and improve the size stability, the same can be done underwear, outerwear, socks, gloves, hats, bed sheets, bedspreads, curtains, mosquito nets, carpets, lace and other clothing, life and decoration with cloth.
Knitted fabric and woven fabric difference
Knitted fabrics and woven fabrics due to the different methods in the weave, in the processing process, fabric structure, fabric characteristics, finished products, have their own unique characteristics, here to make some comparisons.
First, the composition of the fabric organization:
(A) knitted fabrics: is bent by the yarn sequence into coils, and coils in series with each other and the formation of fabric, and yarn formation process of coils, can be horizontal or longitudinal, horizontal knitting called weft fabric, and longitudinal knitting called warp knitted fabric.
(B) woven fabric: is made of two or more groups of mutually perpendicular yarn, to 90 degrees angle for warp and weft interwoven fabric, longitudinal yarn called warp yarn, transverse yarn called weft yarn.
Second, the basic unit of fabric organization:
(A) knitted fabric: the coil is the basic unit of knitted fabric, and the coil is composed of a spatial curve by the circle stem and extension line.
(B) woven fabrics: warp yarn and weft yarn between each intersection point is called the organization point, is the basic unit of the woven fabric.
Third, the fabric organization characteristics:
(A) knitted fabric: because the coil is yarn bending in space, and each coil is composed of a yarn, when the knitted fabric by external tension, such as longitudinal stretch, the bending of the coil changes, and the height of the coil also increases, while the width of the coil is reduced, such as tension is transverse stretch, the situation is the opposite, the height and width of the coil in different tension conditions, obviously can be converted to each other, therefore Knitted fabrics have a large extension.
(B) woven fabric: because the warp and weft yarn interweaving place some bending, and only in the direction of perpendicular to the fabric plane bending, the degree of bending and mutual tension between warp and weft yarn, as well as yarn stiffness, when the woven fabric by external tension, such as longitudinal stretch, the tension of the warp yarn increases, bending is reduced, while the bending of the weft yarn increases, such as longitudinal stretching non-stop, until the warp yarn is completely straightened, while The fabric is transverse contraction. When the woven fabric is stretched by external tension in the transverse direction, the tension of the weft yarn increases and the bending decreases, while the bending of the warp yarn increases, such as stretching in the transverse direction without stopping until the weft yarn is completely straightened, and the fabric shrinks in the longitudinal direction. And warp, weft yarn will not be converted, and knitted fabrics are different.
Fourth, the characteristics of the fabric organization:
(A) knitted fabric: can be extended in all directions, good elasticity, because the knitted fabric is formed by the hole-like coil, have greater breathable performance, feel loose.
(B) woven fabrics: woven fabrics by, weft yarn extension and contraction relationship is not large, and does not convert, so the fabric is generally tight, stiff.
Five, the physical and mechanical properties of the fabric organization:
(A) knitted fabrics: the physical mechanical properties of the fabric, including longitudinal density, horizontal density, square meter grammage, extension properties, elasticity, breaking strength, abrasion resistance, rolled edge, thickness, dispersion, shrinkage, coverage, bulk density.
(B) woven fabrics: the physical mechanical properties of woven fabrics, including warp and weft yarn yarn density, cloth edge, front and back, down and reverse hair direction, fabric coverage.
