The quality advantages of compact yarn are well known, but if we only rely on compact spinning technology as a shortcut to improve spinning quality, and a large amount of related work is not matched to keep up, the gains will outweigh the losses. Therefore, unlike ordinary ring spinning, the application of compact spinning must comply with the following principles.
Principle 1: Reasonable cotton allocation and process optimization
Generally, customers use compact yarn because its price is relatively high and they are used in varieties with higher quality requirements, so the quality requirements for the yarn are also more stringent. Conventional process design is difficult to meet the requirements, and systematic considerations must be made to continuously optimize raw materials and processes to maximize the advantages of compact spinning.
Principle 2: Cleaner production environment
Currently practical Compact spinning basically uses a pneumatic condensation method. Although compact spinning reduces hairiness and flying dust, due to the negative pressure suction, the entire machine becomes a large negative pressure area, which can attract flying flowers and dust generated by adjacent machines. Therefore, compact spinning machines should be placed in a separate room or space and cleaned more frequently.
Principle 3: Cleaning of the grid circle
After a period of operation, the grid Dust, linters, cotton wax, and additives such as honeydew orange in the pre-spinning process will adhere to the surface of the loop, causing the mesh to become clogged or uneven air intake throughout the mesh, resulting in deterioration of the aggregation effect and evenness. Therefore, necessary cleaning and periodic cleaning of the grid circle must be done.
Principle 4: Configuration of steel rings and travelers
Due to the reduction of hairiness in compact spinning , so that the lubricating film between the steel ring and the traveler cannot be formed quickly, so the requirements for the steel ring and the traveler are higher.
Principle 5: Polishing of the top roller shell
According to the main draft, fiber material and Due to different yarn counts and the compact spinning structure requiring a smaller roving stroke than ordinary ring spinning, the polishing cycle of the drafting and yarn-guiding rubber rollers is 8 to 12 weeks, and the grinding amount of each polishing shell is approximately It is 0.15mm on one side. </p
