Five major principles that must be followed to spin well in compact spinning

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 distribution and process optimization

Under normal circumstances, customers use compact yarn. Because its price is relatively high, it is 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

The current practical compact spinning basically adopts the pneumatic condensation method. Although compact spinning reduces hairiness and flying flowers, due to the negative pressure suction, the entire machine becomes a large negative pressure area, which can attract flying flowers produced by adjacent machines. and dust. Therefore, compact spinning machines should be placed in a separate room or space and cleaned more frequently.

Principle 3: Cleaning the Grid Circle

After a period of operation, the surface of the mesh circle will adhere to dust, linters, cotton wax and additives in the pre-spinning process such as honeydew orange, etc., resulting in clogging of the mesh or uneven air suction throughout the mesh, resulting in The agglomeration effect and evenness are deteriorated. Therefore, necessary cleaning and periodic cleaning of the grid ring must be done.

Principle 4: Configuration of steel rings and travelers

Due to the reduced hairiness of compact spinning, the lubricating film between the steel ring and the traveler cannot be formed quickly, so the requirements for the steel ring and traveler are higher.

Principle 5: Polishing the top roller shell

Depending on the main draft, fiber material and yarn count, as well as the fact that the compact spinning structure requires the roving stroke to be smaller than that of ordinary ring spinning, the polishing cycle of the drafting and yarn guiding rollers is 8 to 12 weeks. , the amount of grinding each time the leather shell is polished is approximately 0.15mm on one side.
