Twist of linen yarn refers to the degree to which flax fibers are twisted together during spinning. It describes the degree of twisting of the fibers in the yarn.
Effect Of Twist On Linen Yarn:
- Strength and Durability: The right amount of twist adds strength and durability to the yarn, making it more durable and resistant to tearing and fraying.
- Stability: Twist provides a stable yarn structure that makes it less prone to warping or stretching, helping to maintain shape and dimension stability.
- Appearance and Texture: Twist affects the look and feel of the linen yarn, with a high twist making the yarn tighter and giving it a smoother surface, while a lower twist creates a more natural, rough look.
Pros Of Twist Of Linen Yarn:
- Strength: The right amount of twist can enhance the strength and durability of the yarn, making it suitable for applications with high durability requirements.
- Stability: Twist provides yarn stability and helps maintain shape and dimension stability.
- Appearance: Twist can affect the appearance of the yarn, causing it to take on different texture and appearance characteristics.
Cons Of Twist Of Linen Yarn:
- Rigidity: Excessively high twist may cause the yarn to be relatively rigid, reducing softness and comfort.
- Tangling: Too high a Twist may increase the risk of tangles and twists in the yarn, making it more difficult to handle and use.
Application Scenarios For Twist Of Linen Yarn:
- High Twist yarn is suitable for products that require higher strength and durability, such as outdoor equipment, canvas, woven products, etc.
- Medium Twist yarn is suitable for most home textiles such as bed sheets, curtains, tablecloths, etc.
- Low Twist yarn is suitable for products requiring high softness and comfort, such as clothing, wool
FAQ
What is the twist in linen?
Natural fibers are commonly spun with either an S twist or a Z twist, distinguished by the direction of the fiber’s twisting during thread spinning: S twist rotates to the right, while Z twist rotates to the left.
What is the twist factor of yarn?
The twist factor, denoted as K, is directly proportional to θ when ρ (yarn density) remains constant. Therefore, K serves as a factor that relates the level of twisting to the yarn count. The derivation demonstrates that if two yarns possess the same twist factor, they will exhibit an equivalent surface twist angle, irrespective of the yarn count.
What is the amount of twist in a yarn?
In plied yarns, the twist per inch can be determined by counting the number of bumps within one inch and dividing that count by the number of singles (individual strands plied together to form the yarn).
What is the most common yarn twist?
The majority of single plies produced in manufacturing are spun with a Z twist. When these Z-twisted singles are plied together, they are spun with an S twist to create a balanced plied yarn. This is the common method employed in the production of yarns used by knitters and crocheters, where single plies have a Z twist and plied yarns have a final S twist.
What is S or Z twist yarn?
S-twist yarn is spun in a counter-clockwise direction and is typically utilized in the production of right-handed twill fabric, whereas Z-twist yarn is used for left-handed twill. By employing a yarn twist direction opposite to the twill weave, the resulting fabric is softer compared to fabric made using matching yarn and twill weave.
