1. For the combing system, take the worsted spinning system established in my country in 1968, which is currently used more frequently, as an example. The production process of combed wool top is similar to the top manufacturing process of combed wool yarn production system. The production process of green yarn is:
1) The wool production process: mixed strips─→passes of needle comb─→two passes of needle comb ─→Three needle combs─→Spinning yarn─→Plying─→Shaking yarn─→Files.
2) Knitted velvet production process flow: 1~2 mixed strips─→3~4 needle combing─→roving─→fine yarn─→doubling─→twisting→winding→shaking→binning.
2. The carding system generally spins woolen knitted yarn, and its process flow is:
Raw wool──→ wool selection──→ scouring──→ carbonization──→ matching wool and blending──→ carding
│ → Cooperative stocks → shake twisted.
──→Spin yarn──
│─→Wining.
Since most wool yarns are skein-dyed and then used by sweater factories or sold by commercial departments, a hank machine is used in the last step of the spinning stage to shake it into a certain weight according to the specified length and number of turns. of twisted wire. Usually the weight of a large skein is 250g, each large skein of wool consists of five small skeins, and knitted velvet consists of four small skeins.

Combed yarn generally uses wool or chemical fiber with an average length of more than 75mm, and carded yarn is made of average raw materials The length is about 50mm. When using homogeneous wool, the quality count of thick wool yarn is 46 to 58, and the quality count of fine wool and knitting yarn is 58 to 64. When using heterogeneous wool, use grade 1 to 4 wool for thick yarn, and use grade 1 to 2 wool for fine yarn and knitted yarn. When using acrylic fiber as raw material, the coarse and fine yarns should be 0.56 to 1.1tex (5 to 10 denier), and the knitting yarn should be 0.33 to 0.56tex (3 to 5 denier). In addition, attention should be paid to the requirements for raw materials for dyeing.
