Manufacturer 50D 150T DTY Textured Polyester Twisted Yarn Price

Manufacturer 50D 150T DTY Textured Polyester Twisted Yarn Price

The twist direction of the Polyester Twisted Yarn has a great influence on the appearance 

and feel of the fabric. By combining the twist direction of the warp and weft yarns with the 

fabric structure, fabrics with different styles such as appearance and feel can be woven.

Twisting is to make the two cross-sections of the yarn rotate relative to each other. At this time, the fibers

 in the yarn that were originally parallel to the yarn axis are tilted into a spiral line. For short fibers, twisting 

is mainly to improve the strength of the yarn. The twisting of filaments can not only improve the strength 

of the yarn, but also produce certain effects. The amount of yarn twisting and the coordination of the twist 

direction and twist of the yarn in the fabric have a great impact 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.

Twist:

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

 is called twist. my country's cotton yarn uses special number system twist, that is, the number of twists within 

10 cm yarn length; combed wool yarn and chemical fiber filament use metric count system twist, that is, the 

number of twists per meter; in addition, there is also British count system twist expressed in the number of 

twists per inch.

Twist number: Twist number 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 coefficient is often used to indicate the degree of twist of yarns. The twist coefficient is 

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

 the degree of twist of yarns of different thicknesses. The twist coefficient 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 fiber in a single yarn or a single yarn in a ply yarn after the yarn

 is twisted. It is divided into two types: 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 tilt direction is consistent with the middle of the 

"S" 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 tilt direction is consistent with the middle of the "Z" 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 the ply yarn is expressed according to the twist direction of the twisting. For example, 

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

The twist direction of the ply yarn is expressed as ZSZ.

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

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

appearance and feel can be woven.
