What is vortex spinning? Vortex spinning uses a fixed vortex spinning tube instead of a high-speed rotating spinning rotor. A new spinning method of spinning.
Advantages of vortex spinning:
1, fast speed, high output: equivalent to 4_5 times of ring-spun yarn , the output of one vortex spinning head is equivalent to 2.08 air-jet spinning heads or 8.5 ring spindles output.
2, short process flow, high production rate: vortex spinning uses fiber slivers to directly spin into cheese yarn, so it is not like other new spinning yarns. The yarn is the same, and the two processes of roving and winding can be omitted. Since the breakage rate of vortex spinning is very low and the waste loss is small, the production rate is as high as 99% or more.
3, strong spinning ability, suitable for making fleece products: the yarn structure is relatively bulky, so it has dyeability, pulp absorption and breathability The properties are relatively good, and the yarn’s pilling resistance and abrasion resistance are also relatively good. The range of yarn count is limited to medium and low count yarns, suitable for fleece products.
4. Simple operation and convenient joints: Since the vortex tube is stationary, there is no The high-speed rotating parts make the joint very convenient and simple, and there is no need to clean up after breaking the head, which improves the working environment. Since vortex spinning has no high-speed rotating parts, there is no high-speed bearing lubrication problem, less wear and tear, low noise, and easy maintenance.
Limitations of vortex spinning:
1, vortex spinning The yarn strength is low and unstable, which limits its development into the field of fine yarns, and its competitiveness in the field of fine yarns is not strong yet.
2. Vortex spinning still cannot solve the problem of yarn arms formed when the free end yarn tail rotates at high speed in the vortex tube, resulting in large centrifugal force and tension. . Therefore, it is impossible to make breakthrough progress in its spinning speed.
3. Vortex spinning has its unique advantages and will further replace ring-spun yarn and open-end yarn in the field of knitting yarn. However, it is necessary to continue research and improvement to overcome its disadvantages and limitations and make it a unique new spinning method.
Application scope of vortex spinning blended colored yarn
Knitting: Using knitting needles to form loops of yarns of various raw materials and varieties, and then connecting them through strings. The technological process of knitted fabrics. The coil is the smallest basic unit of knitted fabric, and the coil is composed of a loop trunk and an extended line forming a spatial curve. The coils are nested with each other to form the knitted fabric, and the process of yarn forming coils can be done horizontally or It is carried out longitudinally, transverse weaving is called weft knitted fabric, and longitudinal weaving is called warp knitted fabric.
Woven: It is composed of two sets of mutually perpendicular Yarns are interwoven with warp and weft at an angle of 90 to form a woven fabric. The longitudinal yarns are called warp yarns, and the transverse yarns are called weft yarns. Each intersection point between warp and weft yarns is called a weave point and is the smallest basic unit of woven fabrics.
Wool weaving: using natural wool fibers, wool-type chemical fibers or blended yarns of the two types of fibers as warp and weft yarns, and interweaving them to make various wool fabrics process.
