Analysis of Characteristics of Jet Vortex Color Spinning

Color characteristics

Air jet vortex color spinning yarn has the color characteristics of color spinning yarn. It is different from ordinary yarn and can be divided into two types of products: uniform structure and non-uniform structure.

(1) Products with uniform structure, such as hemp gray yarn, colored yarn, etc., have unique colors. The combination of multi-color fibers in the yarn is uniformly and finely distributed, forming a color blending effect that looks like a single color but is actually a mixture of multiple colors. It is a spatial visual mixing in color theory. Its hazy color artistic effect is unique to ordinary natural color yarn dyeing products. Incomparable.

(2) Non-uniform structure products, such as segmented yarn, colored point yarn, etc., belong to differential structures, and their appearance colors have unpredictable effects such as gradients, which are also impossible to achieve with ordinary natural yarn dyeing products. Since the color characteristics of colored yarn are different from those of ordinary yarn, its product production and development must be supported by personalized processing technology and technology.

Product structural characteristics

Air-jet vortex color spinning has the characteristics of a true-twist wrapped structure of air-jet vortex spinning yarn. A small number of parallel fibers form the yarn core, and most of the fibers wrap around the yarn core on the periphery, forming a core-sheath structure similar to core-spun yarn. This structure determines that its pilling resistance and abrasion resistance are better than ordinary ring spinning and rotor spinning yarns, and it has unique moisture absorption and quick drying properties. However, it also has weaknesses such as low yarn strength.

Based on the above characteristics, the development of air-jet vortex spinning color spinning products should maximize its strengths and avoid weaknesses, give full play to the advantages and characteristics of its yarn structure, and try to make up for or avoid the shortcomings of the product. For example, related products are not suitable for making products that are durable and can withstand high strength, but they are suitable for making fashionable fashions with small batches, multiple varieties, and fast delivery.

Equipment process characteristics

The production process of air-jet vortex color spinning is shorter than that of ordinary ring spinning. It uses sliver feeding and direct spinning into package yarn, eliminating the two processes of roving and winding, thus greatly shortening the spinning process , saving infrastructure and equipment investment costs, and also reducing labor usage. What needs special attention is that the air-jet vortex spinning machine has the characteristics of ultra-large drafting device and high output and high speed, and has relatively high requirements for fiber raw materials and temperature and humidity environment. Generally speaking, fiber raw materials are more likely to form floating fibers under such ultra-large draft conditions, and high-speed rotating rubber rollers are more likely to cause fiber entanglement problems. These will cause the fiber movement to be out of control and ultimately lead to a decline in yarn quality. Therefore, in The jet vortex color spinning process should focus on this.
