Third, according to the spinning system: 1. Worsted wool spinning Worsted wool yarn, also known as combed yarn, refers to the finished yarn spun by combing process, including combed cotton yarn and combed wool yarn. The parallel straightness of the fibers in the yarn is high, and the evenness is even and smooth, but the cost is high and there are many yarns. Combed yarns are mainly used as raw materials for high-grade fabrics and knitwear, such as worsted, gabardine, tweed and sweaters. 2. Coarse spinning. Coarse spinning, also known as carded wool yarn or carded cotton yarn, refers to the yarn that is combed according to the general spinning system and spun without combing process. Coarse spun staple fiber has many dimensions, poor fiber parallelism and straightness, loose structure, many hairiness, low yarn count and poor quality. This kind of yarn is mostly used as raw material for general fabrics and knitwear.
Fourth, according to the yarn structure: 1. Single yarn: A single yarn is a yarn in which only one fiber bundle is twisted. One raw material can be spun into pure yarn to form pure textile, and two or more raw materials can be spun into blended yarn to form blended fabric. 2. shares:? A plied yarn is a yarn formed by twisting two or more single yarns. Its strength and wear resistance are better than that of single yarn. At the same time, the strands can be combined and twisted in a certain way to obtain multi-stranded twisted strands, such as double-stranded, triple-stranded and multi-stranded strands. Mainly used for sewing thread, braided thread or medium-thick strong fabric. 3. monofilament:? Monofilaments consist of fiber filaments. Its diameter depends on the thickness of the filament. Generally, it is only used for processing thin fabrics or knitted fabrics, such as nylon stockings and face towels. 4. textured yarn:? Textured yarn is obtained by deforming synthetic fiber filaments from flat to curly, also known as textured yarn or processed yarn. Textured yarns include high elastic yarns, low elastic yarns, bulked yarns and mesh yarns.
