Controlling yarn count requires the use of satisfactory raw materials and manufacturing processes. The Blendomat feeding system opens, conditions, and feeds cotton in small lumps to the blowroom. Chute feeding to carding machinery and high speed drawing help improve yarn count, particularly when online monitoring and an autoleveler are used. Optimal drawing requires 4 over 3 drafting with a pressure bar for short staple fibers and no pressure bar for long staple fibers. Depending on the speed of delivery, loading may be spring, pneumatic, or hydraulic. For speed frames, researchers recommend 4 over 4 drafting with the condensing zone at the front. Ring spinning machines, humidity control, and the elimination of trash and microdust from cotton also affect count control
