Torque
In textiles, torque refers to the amount of twisting or spiral deformation that occurs in yarn or fabric during the manufacturing process. This twisting can occur naturally, due to the inherent properties of the fibers used in the yarn or fabric, or it can be deliberately introduced through the spinning or weaving process.
The degree of torque in a yarn or fabric can have a significant impact on its properties, including its strength, stretch, and overall durability. Excessive torque can cause yarns or fabrics to become stretched or distorted, leading to uneven texture or surface appearance.
Torque is typically measured in terms of its twist angle, which is defined as the angle between two adjacent fibers or threads in a twisted yarn or fabric. The greater the angle, the greater the degree of twist and the higher the torque.
In the spinning process, torque is introduced through the twisting of fibers to create a cohesive yarn. The amount of twist applied will depend on the type of yarn being produced and the desired properties of the finished product. For example, a yarn intended for use in a knit garment may require less twist than a yarn intended for use in a woven fabric.
During the weaving process, torque can be introduced through the tension and movement of the warp and weft threads as they are interlaced. This can result in a spiral deformation of the fabric, which can have both positive and negative effects on its properties.
On the one hand, a moderate amount of torque can give a fabric a more structured, firm feel and help it retain its shape over time. This can be particularly important for certain types of garments, such as tailored suits or formal dresses.
On the other hand, excessive torque can lead to a number of issues, including uneven shrinkage, distortion of pattern or design elements, and even tearing or breakage of the fabric. This is particularly true for knitted fabrics, which are more prone to distortion and deformation due to their inherent stretchiness.
To minimize the negative effects of torque in textiles, manufacturers may employ a range of techniques, including careful selection of fiber types, precise control of spinning and weaving parameters, and the use of specialized equipment such as tension sensors or stabilizing frames.
In summary, torque in textiles refers to the degree of twisting or spiral deformation that occurs in yarn or fabric during the manufacturing process. The degree of torque can have a significant impact on the properties of the finished product, including its strength, stretch, and overall durability. Manufacturers employ a range of techniques to control and minimize torque, including careful selection of fiber types and precise control of spinning and weaving parameters.
Torque
A term applied to a type of nylon yarn which has been through processing to introduce a high level of twist. This creates a yarn with some recovery but without "bulk" associated with texturised yarns. A style made from these yarns is sometimes called Volie. The fabrics made from Torque yarns have excellent sheerness for a given denier and bright surface appearance. However the overall cling properties in wear are limited and multiple sizes are needed to get a good fit.
Torque
A force which tends to cause rotation, usually due to twist having been inserted into a yarn or removed from a yarn (see twist liveliness).
