Polyester Yarn Application

Certificat

Twisting is to make the two cross-sections of the yarn produce relative rotation. At this time, the fibers 

in the yarn that were originally parallel to the yarn axis are tilted into a spiral line. The twisting of filaments 

can not only increase the strength of the yarn, but also produce a certain effect. The amount of yarn 

twisting and the coordination of the twist direction and twist of the yarn in the fabric have a great influence 

on the appearance and performance of the product.

The indicators of twisting properties are: twist indicating the degree of twisting, twist coefficient and 

twist indicating the twisting direction.

The twist angle of the yarn is twisted one circle as one twist. The number of twists per unit length of 

the yarn is called twist. In my country, cotton yarn uses the special number system twist, that is, the 

number of twists within 10 cm yarn length; combed wool yarn and chemical fiber filament use the 

metric count system twist, that is, the number of twists per meter; in addition, there is also the imperial 

count system twist expressed in the number of twists per inch.

Twist factor Twist cannot be used to compare the degree of twist of yarns of different thicknesses, 

because with the same twist, the fiber inclination of thick yarns is greater than that of thin yarns. 

In actual production, the twist factor is often used to indicate the degree of twist of yarns. Twist factor

 is a relative value of the degree of twist of yarns combined with linear density, which can be used to 

compare the degree of twist of yarns of different thicknesses. The twist factor can be calculated based 

on the twist of the yarn and the linear density of the yarn.

Twist direction

Twist direction refers to the tilt direction of the fibers in a single yarn or a single yarn in a ply after the 

yarn is twisted. It is divided into Z twist and S twist. After twisting, the twist direction of the yarn tends 

from the lower right corner to the upper left corner, and the inclination direction is consistent with the 

middle of "S", which is called S twist or forward twist; the twist direction of the yarn tends from the 

lower left corner to the upper right corner, and the inclination direction is consistent with the middle of 

"Z", which is called Z twist or reverse twist. Generally, single yarns are often twisted in Z twist, and ply 

yarns are twisted in S twist.

The twist direction of ply yarns is expressed according to the twist direction of twisting in sequence. 

For example, the twist direction of single yarn is Z twist, the primary twist is S twist, and the secondary

 twist is Z twist.

The twist direction of yarn has a great influence on the appearance and feel of the fabric. By combining 

the twist direction of warp and weft yarns with the fabric organization, fabrics with different styles such 

as appearance and feel can be woven.
