How to divide the fabric in the warp and weft directions

How to distinguish the warp and weft of fabric:
If the identified fabric has a selvage, the yarn direction parallel to the selvage is the warp direction, and the other is the weft direction.
Sizing is in the direction of warp, and non sizing is in the direction of weft.
All fabrics have selvage. The direction along the selvage is the warp direction, and the direction perpendicular to the selvage is the weft direction
For fabrics with obvious reed marks, the reed mark direction is the warp direction.
For half thread fabrics, the ply direction is generally the warp direction and the single yarn direction is the weft direction.
If the twist and draw of single yarn fabrics are different, the Z twist direction is the warp direction and the S twist direction is the weft direction.
If the warp and weft yarn count, twist direction and twist of the fabric are not very different, the warp direction is the one with even yarn lines and good luster.
If the yarn twist of the fabric is different, most of the higher twist is in the warp direction, and the lower twist is in the weft direction.
In the interwoven fabrics of different materials, cotton wool or cotton hemp interwoven fabrics are generally made of cotton as warp yarn; In wool interwoven fabric, silk is warp yarn; In woolen silk cotton interwoven fabric, silk and cotton are warp yarns; In the interwoven fabric of natural silk and spun silk, natural thread is warp yarn; In the interwoven fabric of natural silk and rayon, natural silk is the warp yarn.
Introduction to fabric warp and weft:
Woven fabric is made of two or more groups of mutually perpendicular yarns with ∠ 90 ° as warp and weft. The yarn in the length direction of the fabric is called warp, and the yarn in the width direction is called weft. Due to the wide range of uses and varieties of fabrics, the requirements for raw materials and organizational structure of fabrics are also varied, so the judgment should be made according to the specific conditions of fabrics.
Fabric introduction:
Fabric is the material used to make clothes. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the performance effect of clothing color and shape. Fabrics are mainly divided into two categories according to the source of processing materials. One is called natural fiber, which means that the original processing materials come from nature. It is also divided into animal fibers, such as common wool fibers and silk fibers.
Common clothing fabrics:
Cotton fabric: refers to the fabric made of cotton yarn or cotton and cotton chemical fiber blended yarn. It has good air permeability, moisture absorption and comfortable wearing. It is a popular fabric with strong practicability. It can be divided into pure cotton products and cotton blends.
Hemp type fabric: pure hemp fabric woven from hemp fiber and fabrics blended or interwoven with hemp and other fibers are collectively referred to as hemp type fabrics. The common characteristics of flax type fabrics are hard and tough, rough and stiff, cool and comfortable, and good moisture absorption. They are ideal summer clothing fabrics. The flax type fabrics can be divided into pure spinning and blended spinning.
Silk fabric: It is a high-grade variety of textiles. It mainly refers to the fabrics made of mulberry silk, tussah silk, rayon and synthetic fiber filament. It is thin, light, soft, smooth, elegant, gorgeous and comfortable.
Wool type fabric: it is a fabric made of wool, rabbit hair, camel hair, wool type chemical fiber as the main raw materials. It generally lives in wool. It is a high-grade clothing fabric all the year round. It has the advantages of good elasticity, wrinkle resistance, stiffness, wear resistance, strong warmth retention, comfort and beauty, and pure color, and is welcomed by consumers.
