Frequent question: How many spinning systems produce condensed yarn?

What is condensed yarn spinning?

In the condensed spinning process, the fibre assembly is condensed before twist insertion, so that there is no longer a need for the spinning triangle. All the fibres receive their prescribed degree of twist and are incorporated in the fibre assembly.

What are the different types of compact spinning technology?

There are three major manufacturers in the field of compact spinning machines namely, Sussen (Elite spinning), Rieter (Comfor spin), and Zinser (Air-Com- Tex 700).

condensation can be achieved by the following means:

  • Roving twist: The twist in the roving has twofold. …
  • Mechanical condenser: The condensation of the.

What is compact spun yarn?

In compact spinning, fibers in drawing stage are condensed using air suction, which results in the produced yarns which significantly differ from ring spun yarns in their physical and mechanical properties.

How is yarn prepared by spinning?

The term ‘spinning’ can be referred to the whole activity or just to the final process of making the yarn from fibers. This involves attenuating (stretching) the yarn to the required tex giving the thread strength by adding a twist and winding to on a bobbin.

Which yarn has the highest strength?


Vectran fiber exhibits exceptional strength and rigidity. Pound for pound Vectran fiber is five times stronger than steel and ten times stronger than aluminum.

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.

What is spinning triangle?

The spinning triangle is a critical region in the spinning process of staple yarn. Its geometry influences the distribution of fiber tension at spinning triangle directly and affects the qualities of spun yarns. … Spinning triangle division is one of the most effective measures, such as solospun technology.

How can you tell if a yarn is compact?

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.

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.

Why the amount of sizing required for compact spun yarn is less?

The increase in cost associated with compact spinning can be justified on the basis of the lower twist required to make the yarn (softer yarn) at a comparable strength to that of conventional ring spun yarn, lower size add-on during sizing and substantially fewer stops or yarn breakage during rope beaming as a result …

What is carded compact yarn?

Get Latest Price. We produce compact cotton carded yarn for use in many industries. We use compact spinning to control the mixture of protruding fibers (uncontrolled fibers) with cotton yarns. We achieve uniform yarn formation due to this process.

What is yarn count system?

In textiles, yarn count is a number that represents the diameter or fineness of a yarn, either in terms of weight by length or length by weight. … The indirect system measures the length of a consistent weight of yarn, with a higher yarn count indicating a finer yarn.

What are the spinning process?

Spinning is the process of turning natural fibers and synthetic filaments into yarn. Fibers are short hairs of natural materials like cotton. … To make synthetic yarns, which are made of filaments extruded from man-made materials, different processes are used. These include melt spinning, dry spinning, and wet spinning.

How does the spinning mill work?

A spinning mill opened raw cotton bales and cleaned the cotton in the blowing room. The cotton staples are carded into lap and straightened and drawn into roving which is spun using either a mule or ring frame. The yarn can be doubled and processed into thread, or prepared for weaving.

What is the spinning mill process?

Spinning Process – A Conversion Process Of Fibers Into Yarn. … People used to convert fibers into yarn i.e. the spinning process by hand before a couple of decades which has now been mostly replaced by advanced technology of mechanical spinning carried in textile mills.
