A process for three-hank tight spinning of multi-component dtys orona filaments
By using a multi-component DTY Sorona filament three-soft compact spinning process, the problem of tension loss in DTY Sorona filament during core-spun and Siro-spun spinning has been solved, achieving stability in yarn quality and improvement in fabric performance, especially in terms of significant improvements in hairiness, strength, abrasion resistance, bulkiness, wrinkle resistance, moisture wicking and breathability.

AI Technical Summary
DTY Sorona filaments are prone to problems such as tension loss, core exposure and off-center core, uneven doubling, and filament splitting in core-spun and Siro-spun processes, resulting in unstable yarn quality and difficulty in ensuring fabric elasticity and dimensional consistency.
The multi-component DTY Sorona filament three-soft compact spinning process is adopted. Through the combination of multi-component fine cotton blending and combing, pre-drawing, drawing, roving and three-soft compact spinning machine, the tension of the filament is controlled by the guide tensioner and the five-roller sliding roller. Combined with triple guide rollers and light flexible steel wire traveler, the drafting, twisting and winding are realized to produce three-soft compact yarn.
It significantly improves the yarn's hairiness, strength, evenness, abrasion resistance, bulkiness, wrinkle resistance, moisture wicking and breathability. The fabric is soft to the touch, has a high elastic recovery rate, and improves weaving efficiency, making it suitable for high-frequency use scenarios.
