The core application scenarios of rotor spinning machines (also known as air flow spinning machines) are concentrated in the fields of textile and clothing, household and commercial kitchen equipment, industrial textiles, etc. Its high efficiency, energy saving, and strong adaptability to raw materials have promoted the upgrading of traditional textile technology and the expansion of emerging markets. Here is a specific analysis:

1. Textile and clothing field: comprehensive coverage from coarse and thick fabrics to high-end fabrics

Production of coarse and thick fabrics

Rotary spinning machines have become the preferred equipment for coarse and thick fabrics such as denim, corduroy, and labor fabrics due to their fast spinning speed and large roll characteristics. Its yarn structure is fluffy and wear-resistant, perfectly meeting the durability and texture requirements of this type of fabric. For example, in denim production, rotary spinning can achieve efficient impurity removal, reduce yarn defects, and improve fabric uniformity.

The mainstream choice for medium and low count yarns

In the cotton spinning industry, rotor spinning has evolved from traditional medium and coarse count yarns (such as 190-13/3-45 count) to combed yarns, low count yarns, and knitted yarns.

. By optimizing the design of the combing roller and rotor, modern models can produce high count yarns of over 40S, meeting the needs of lightweight fabrics such as shirts and T-shirts. For example, a certain enterprise in Jiangsu produces 40S rotary cup yarn from combed cotton as raw material, with low cost and standard quality.

Blended and Differentiated Yarn Innovation

Rotary spinning supports multi-component blending, such as linen/cotton, wool/polyester, recycled fibers, etc., expanding the application fields of products.

. By using dual feeding combing mechanism or three channel rotary cup technology, various fancy yarns such as bamboo yarn and color spun yarn can be produced for high-end markets such as decorative fabrics and knitted velvet fabrics. For example, polyester/wool blended yarn prepared by rotor spinning has better wear resistance and pilling resistance than traditional semi precision spinning.

2. Household and commercial kitchen equipment: solutions for efficient smoke exhaust and noise reduction requirements

Range hood motor drive

DC brushless rotary cup motor has become the core power source of high-end range hoods due to its high efficiency, energy saving, and low noise characteristics.

. Its infinite speed regulation function (0-1800 revolutions per minute) can match cooking scenarios in real time: high-speed operation during stir frying (instantaneous suction ≥ 20m ³/min), low-speed operation during steaming (noise<40dB), balancing smoke exhaust effect and user experience.

Commercial kitchen smoke exhaust system

In commercial scenarios such as restaurants and hotels, the rotary cup motor drives high-power fans to achieve high air volume (≥ 5000m ³/h) and high pressure head (≥ 500Pa), quickly eliminating a large amount of oil fume and odor.

. Combined with sensors and frequency converters, the system can automatically adjust the speed according to the concentration of oil fumes, increasing energy efficiency by more than 20%.

III. Industrial Textiles: Supporting Technologies for Functional and Environmental Protection Requirements

Medical and Health Materials

Rotary Spinning can produce short fiber yarns for non-woven fabrics, which are used in medical supplies such as surgical gowns and masks.

. Its efficient impurity removal and antibacterial treatment technology ensures that the yarn meets hygiene standards. For example, regenerated cotton yarn prepared by rotary spinning (with a ratio of 30% to 80%) can be used for low value medical consumables after treatment.

Aerospace and New Materials

In the field of high-performance fibers such as carbon fiber and aramid, rotor spinning optimizes the design of the spinning cup and false twist device to reduce fiber damage and improve yarn strength.

. For example, a certain enterprise uses diamond coated spinning cup to produce rotor yarn for aviation interior materials, which has significantly better wear resistance than traditional yarn.
