There are two ways to solve the problem of yarn strength. One is to use more advanced spinning technology without changing the raw materials to produce yarns suitable for easy care fabrics, such as compact ring spinning technology.
The second method is to adjust the raw materials and change the yarn structure, through the combination of the original natural fiber and the fiber with excellent performance and easy care requirements through certain spinning methods, to get the ideal yarn, mainly including blended yarn and composite yarn, which are introduced below.
1. Blended yarn
The mixed spinning of two or more kinds of fibers mainly adopts bulk fiber mixing and sliver mixing. Through the original fiber raw materials and other fibers with high strength and high modulus to increase the strength of the whole yarn. This kind of composite yarn includes traditional polyester / cotton, polyester / viscose, polyester / wool, etc., as well as polyester / cotton / Tencel fiber, polyester / cotton / cashmere, etc.
2. Composite yarn
Two kinds of different fibers are intertwined by single yarn or filament, similar to strand structure, which can be spun on the reformed spinning frame or on hollow spindle. It mainly includes siro spinning, sirofil spinning, wrapping spinning, core spinning, etc.
