There are two solutions to the problem of yarn strength, one is to use more advanced spinning techniques without changing the raw material to spin yarns that can be adapted to easy-care fabrics, such as compact ring spinning technology.
The second method is to use the method of adjusting the raw materials and changing the yarn structure, through the original natural fiber and the fiber with excellent performance and easy care requirements through a certain spinning method to combine the two to obtain the ideal effect of the yarn, mainly blended yarn, composite yarn, etc., which are introduced below.
1. Blended yarn
Mixed spinning of two or more fibers is mainly carried out in the form of bulk fiber blending and strip blending. The strength of the whole yarn is increased by the original fiber raw material and other fibers with high strength and high modulus. Such composite yarns include traditional polyester/cotton, polyester/viscose, polyester/wool, etc., as well as polyester/cotton/Tencel fiber, polyester/cotton/cashmere, etc.
2. Composite yarn
Two different fibers are intertwined in single yarn or filament yarn with a similar strand structure, which can be spun on a modified spinning frame or on a hollow spindle. There are mainly siro spinning, selophil spinning, wrapping spinning, core spun spinning and so on.
