Neps are highly entangled fibres. Usually a nep contains ten or more fibres. It is a very serious problem in the textile industry.

The ease with which a fibre forms part of a nep is related to its bending rigidity. Immature cotton and fine fibres bend easily. They are prone to nep formation during carding. Many neps often persist into the final fabrics. Neps contain many immature cotton fibres, which have less cellulosic materials than mature fibres. During fabric dyeing, they do not take up as much dye as the rest of the fabric, causing a serious fabric fault known as "white specks".

Closer card settings between adjacent surfaces, sharper teeth, and higher doffer speed (reducing "recycling fibres") can be used to reduce the number of neps in carding.

What is definition of imperfections in ring spinning yarn?

Imperfections in the yarn refer to the total number of thin places (-50%), thick places (+50%) and neps (+200%) present per kilometer of yarn.A thin place is where the count of the yarn is half to the actual count of the yarn.A thick place is where the count of the yarn is 50% greater than the actual yarn count. Means the total count at a thick place will be 150%.A nep is a small entanglement of fibers which has a size double to the actual count of the yarn.


How do you Determine the Nep Impurities in the Fabric?

Nep is produced by poor ginning quality or spinning process handled poorly of fiber, immature cotton or dead cotton.Discriminant method is as follows: (1) Nep in the yarn, regardless of yellow, white, round, flat, big or small, if it can be identified by the examiner 's eyesight,we called it nep. (2) Fibers gathered into a group, regardless of loose and tight, are called nep. (3) Neps formed by immature cotton, dead cotton (pieces, lices,strips), are called nep. (4)Though yellow and white fiber are not formed nep, it formed flock and part of them wrapped around the yarn is called nep. (5) Adhesional neps, are called nep. (6) Neps with impurities, we called them neps,not impurities. (7) All thick cotton yarn evenness, checked according to evenness, not neps.

What is siro yarn?

What is ring spun carded and combed yarn and what are their uses?

There are three commercial methods of spinning yarn into the product we see at the store. They are called Ring Spun, Rotor Spun, and Friction Spun. Each method produces different results in the yarn. The full question, ring spun carded and combed, refers to the fiber preparation method of carding (brushing) and combing the fibers prior to spinning, in order to form a softer yarn which is best for soft knit items. The fibers are spun in a ring arrangement making it unnecessary for extra plies, so the yarn is much finer. There is also a downside to using ring spun, because the very process that causes it to be softer also causes the yarn to be more prone to breaking.


What is the significance of traveler in ring frame?

1.To insert twist to the yarn. 2.To wind yarn on the spinning cop. 3.To give enough tension thereby producing compact spinning cop which in turn increases the cop content in terms of weight and length


How do you improve Elongation percent in Ring spun Yarn?

There are three commercial methods of spinning yarn into the product we see at the store. They are called Ring Spun, Rotor Spun, and Friction Spun. Each method produces different results in the yarn. Increasing the elongation percent in Ring Spun yarn requires a fiber preparation method of carding (brushing). This will produce a softer, longer yarn whis is best used for knitted items.


What is neppy yarn?

Basically neps is a problem of yarn but it may be a ornamented yarn if it can be arranged in a organized way. As for example: (95%Cotton+5%Polyester) Neppy Yarn Base yarn is cotton & if some dyed polyester of different color can be sprayed throught its length & base yarn is dyed then one kind of neppy effect will be visible throughout the length of the yarn. This yarn is called Neppy Yarn.
