Ring-spinning has been the most common technology in producing yarns because of the excellent softness and structure of its end products and its applicability on different materials. However, a residual torque (or twist liveliness) tends to build up in the yarn as the twist is inserted. Such torque results in spirality and distortion of single jersey knitted fabrics, and surface unevenness of denim fabric after stone-wash finishing. For instance, some T-shirts would have crooked seams that curl towards the front or the back after a few washes. This is a result of the residual torque built up in the yarn during the spinning process.
This is a new technology that produces ring-spun yarn with no torque and low hairiness. Fabrics weaved with the yarns produced from this technology exhibits excellent softness, surface clearness and dimensional stability. Garments made with such fabrics would not twist or distort even after many washes.
Using low or zero residual torque produced singles ring yarn is a new technology which can be incorporated into the conventional ring-spinning process without any additional processing step. It simply requires adding a mechanical device to the existing spinning machine to achieve fibre torque balance.
This technology makes a revolutionary breakthrough in the textile industry:
This technology is applicable to woven, knitted and denim fabrics. In terms of material, cotton is most commonly used in garments and textile products, for example, towels, T-shirts and polo shirts. Low or zero residual torque produced fabric is hugely popular in high-end markets throughout the world, including Europe, the U.S. and Japan. Knitted sweaters made by this technology are particularly well-received in Japan, mainly because they do not distort even after repeated washes. A Japanese casual wear chain used this technology in T-shirts and jeans, and their products have entered the high quality and value-added market worldwide.
Catering to the increasing demand of high quality textile products, the technology improves manufacturers production capability and enhances their production efficiency by producing yarns with low residual torque and high strength.
