Once the regime spandex yarn is pre-drawn 3.five occasions, the creep resistance is most effective. It should be precisely modified in accordance with the usage tone plus the type of its downstream cloth.
Parallel or textured polyamide yarns can be used to make the double address. The double coated thread is utilized to make apparel, underwear and hosiery of top quality and superb performance.
However SCY has decreased Main publicity, generally less likely to result in good quality challenges in spinning and weaving, aside from uneven twists, however, its production efficiency is minimal. As a result, the cost is in excess of RMB 5000/T larger than the same schedule of ACY. The cost of FDY is a lot more than RMB 10000/T increased than the exact same regime of ACY. Thus it enormously improves the expense of utilizing the SCY.
At Herng Fa, our SCY can be tailored to meet specific purchaser wants. The customization options involve deciding on various key yarns (including functional yarn or shade yarn) and matching yarns (functional yarn) to build distinctive SCY with possibly S or Z twists.

when the twist is simply too lower, the outer covering fibre is usually free and impact the masking result, which can lead to the core publicity, so the twist really should be large in mechanical wrapping. However, if the twist is too substantial, The material feels stiff and drapes improperly.

This twin-layer wrapping approach don't just improves the sturdiness and elasticity from the yarn and also enables for various twist angles to create various cloth hand feels.
Air covered yarn makes use of the principle of compressed air to intricately entangle and Incorporate a key yarn using a matching yarn, usually spandex.
