Abstract. Compact-Siro spinning technology is one of the most widely used spinning methods. It is conducted on a compact ring frame by simultaneously feeding two rovings into the drafting zone at a predetermined separation.
What is Siro yarn?
Siro Yarn is made with a process of Siro Spinning or Elitwist spinning. In this, the yarn is made into 2 ply on the ring spinning machine. There are lot of benefits of Siro spinned yarns. Siro Yarns are available in Carded, Combed, Carded Compact and combed Compact.
What is Siro viscose?
SIRO SPUN™ – SPINNING PROCESS
Traditionally, two-fold yarns have been used for weaving because they are stronger, and the twisting operation binds the surface fibers into the yarn structure so that it is smoother and more resistant to abrasion during weaving.
What is the difference between compact and combed yarn?
The difference between the evenness values of conventional and compact spun carded yarns increases as the yarn becomes coarser. Combed compact yarns have higher evenness values than combed conventional ring yarns. The interaction effect of spinning system and yarn linear density is statistically significant.
What is compact yarn?
Compact yarns have no long hairs, which allows easier sizing of the yarn (the amount of sizing agent needed can be reduced by up to 50%) and provides an effective shedding process. From: Advances in Yarn Spinning Technology, 2010.
What is a melange yarn?
A melange yarn is the yarn which is produced with various combinations of raw white & dyed cottons or dyed fibers. For example, if we mix 99% raw white cotton & 1% dyed cotton (of any color), then it will be called “Melange” yarn.
What is injected yarn?
Injected slub yarn is a kind of fancy yarn with special structure developed by injection of coloured or different types of fibres. Effect yarns produce an enhanced aesthetic impression as well as ornamentation in the fabric.
How do you make Eli twist yarn?
Single yarns were spun on a Lakshmi spinning line and doubled on a Saurer compact twist TFO machine. All yarns were spun using 40 twist factor. To produce Eli-Twist yarn, the distance between the two roving strands in drafting system was kept at 8 mm and a negative pressure of 30 mbar was maintained.
What is core spun yarn?
Core-spun yarns: Core-spun yarns have a central core that is wrapped with staple fibres, and are produced in a single operation at the time of spinning. For example, a cotton sheath for handle and comfort, with a filament (often polyester) core for added strength; or cotton over an elastomeric core.
What is the difference between combed and carded yarn?
Normally, carded yarn strength is lower than combed yarn of the same count. Carded yarn is more hairy than combed yarn. Combed yarns are more lustrous than carded yarns. … Less amount of loose hairy fibers are removed from combed yarn by knitting process and pretreatment process than carded yarn.
Why is compact yarn called so?
2. This condensing of fiber strand considerably reduces the width of spinning triangle and hence problems associated with spinning triangle. … The yarn produced on this system is named by Rieter as COM4 yarn.
What is combed compact yarn?
Combed Compact Yarns that are made from premium quality materials like cotton and other synthetic fibers that ensure long life and premium quality. … Widely Used In: Textiles industry. Apparels industry.
What are the different types of compact spinning technology?
The compact spinning system by Zinser supplied under the trade name of CompACT3, is a pneumatic (aerodynamic) compacting system based on the fibres bundling/compacting via several suction points(10).
- Perforated drum.
- Suction system.
- Bottom roller.
- Top roller.
- Nip roller.
- Air guide element.
What is the difference between open end and ring spun yarn?
Ring-spinning, which is a system of spinning using a ring and traveler take-up, twists and winds the yarn simultaneously and continuously. Open-end spinning, on the other hand, is a system of spinning where the yarn is twisted by rotating at the hap or break in the flow (the fibers wrap around the yarn v.
What are the types of yarns?
They include such types as fingering yarns, usually of two or three plys, light to medium in weight and with even diameter, used for various types of apparel; Germantown yarns, soft and thick, usually four-ply and of medium weight, frequently used for sweaters and blankets; Shetland yarns, fine, soft, fluffy, and …
