You still don't understand what spinning is?

       Today, we strongly recommend related content on "spinning methods" for you, and perhaps you can benefit a lot from it. Let's take a look together.

       Spinning is the entire process of processing textile fibers into yarn. "Spinning" means the formation of fibers into slivers and the drawing and twisting of them into yarn. Some countries also refer to chemical fiber spinning and reeling from cocoons as spinning, while in China, chemical fiber spinning and reeling are referred to as spinning, respectively. What kinds of spinning do we have? This article will take you to understand the types of spinning and its spinning methods.

       Ring spun yarn

       Ring spinning is the most commonly used and widely used spinning method in the current market. After the sliver or roving is drawn, the fiber sliver is introduced by rotating the ring bead, the bobbin winding speed is faster than the bead, and the cotton yarn is twisted to form a spun yarn. Widely used in various short fiber spinning projects, such as carding, combing, and blending, the steel ring is driven by the bobbin through the sliver to rotate around the steel ring for twisting. At the same time, the friction of the steel ring causes its rotational speed to be slightly lower than the bobbin, resulting in winding. The spinning speed is high, and the shape of the ring spun yarn is a conical spiral thread with most of the fiber dimensions transferred from inside to outside, making the fibers wound and connected inside the yarn. The yarn has a compact structure and high strength, Suitable for various products such as thread making, weaving, and knitting.

       Compact spinning

       Compact spinning is a new spinning technology that spins on an improved new ring spinning frame. The main spinning mechanism is that a fiber condensation zone is added in front of the traction device of the ring spinning frame, basically eliminating the spinning twist triangle between the front roller and the twist point. After the fiber strands are output from the front opening of the front roller, they first pass through the outer mesh leather loop of the profiled air suction pipe, and the strands move on the mesh leather loop. Due to the contraction and polymerization of the air flow, the strands are gathered and rotated through the air suction slot of the profiled pipe, gradually turning from a flat ribbon to a cylindrical body. The ends of the fiber strands are twisted into the yarn, resulting in a very tight yarn, with a smooth and clean appearance and less hairiness. Compact spun yarns have higher strength and less hairiness. The phenomenon of galling is the least likely to occur during the weaving process.

       Sirospun

       Siro spinning, also known as parallel twist spinning, is known as A and B yarns in China, and has recently been officially named Siro spinning. Siro spinning is the process of feeding two rovings with a certain spacing on a spinning frame, and after drafting, the two single strands are output from the front roller. The transmission of twist by the pla/colored cotton Siro spinning yarn causes a small amount of twist on the single strand, which is further twisted into a similar stranded yarn after splicing and wound on the bobbin.

       Its purpose is to be used in wool spinning, characterized by low hairiness, high strength, and good wear resistance, achieving the effect that wool yarns can be woven with a single yarn, in order to achieve lightweight wool fabrics. Although Siro spinning has greatly improved compared to similar conventional yarns in many aspects, there is still a certain distance to truly achieve non sizing weaving of wool single yarns. The grade of raw materials used in siro yarns can be lower than that of conventional ring spun yarns, while their fabrics have less hairiness, a soft feel, wear resistance, and good breathability compared to conventional ring spun ply fabrics.

       Cerofil spinning

       Sirofil spinning is also known as Sirofil composite spinning. "It is a spinning technology developed on the basis of Siro spinning, with the difference being that one roving in Siro spinning is changed into filament, which is twisted into yarn with the other roving, and processed after being modified on a ring spinning frame.". Sirofil spinning consists of two components, the first component generally being wool, and the second component generally being filament or staple pre spun yarn. On a spinning frame, the first component of wool roving passes through normal drafting, while the second component of filament is fed directly from the front roller without drafting. After being output from the front roller, the two components are directly combined and twisted to form yarn in one step. Wool worsted yarns are often wrapped or wrapped with polyester, polypropylene, and nylon filaments.

       Solo spinning

       Solospun, also known as cable spinning, is a small grooved roller (dividing roller) installed in front of the traditional ring spinning front roller. Under the action of the small grooves of the SolospunTM roller, the drafting whiskers are divided into two to three (or even four) strands, each strand being initially twisted and forming a small twisting triangle. Finally, each strand leaves the SolospunTM roller and is twisted together to form SolospunTM yarn.

       Embedded composite spinning

       Embedded composite spinning is a new spinning technology with independent intellectual property rights that has emerged in China in recent years. Its characteristics can be vividly understood as the combination of two sirofil yarns. Two short fiber rovings are fed in parallel at a certain distance from the rear bell mouth, while the other two filaments are fed directly from the front roller at the outer side of the roving strand through a wire guide device. The two rovings and filaments are initially assembled and pre twisted, respectively, before being assembled and twisted together to form yarn, Therefore, two small twist triangles and a large twist triangle are formed outside the front jaw. This twisting method forms a unique ply yarn structure, with the yarn strength mainly borne by the filament. The twisting process realizes the transfer of short fibers inside and outside and is fixed by the embedded filament. Its structure is essentially different from the internal and external transfer of fibers in traditional ring spinning.
