Slub yarn is yarn that is intentionally spun with thicker sections, or slubs, to give fabric more texture and personality. There are several factors that influence the visual effect of slub yarn, including the number of slubs per kilometer, diameter of each slub, length of each slub, and distance between slubs. Slub yarn can be regular/patterned, irregular/non-patterned, or a combination of both patterned and non-patterned. Slub yarn is produced on ring frames by varying the speed of the back and middle rollers to create slubs at controlled intervals. It is used in fabrics like upholstery, lace, curtains, and

Slub yarn: Slub yarn refers to yarn that has been purposely spun with slubs(thicker sections

along the yarn). While it was once seen only as a defect, slub yarn is now intentionally created to

give fabric more personality.

Four factors which affect the visual effect of slub yarn:

1. No. of slubs per kilometer

2. Dia of slub

3. Length of slub

4. Distance between slub

All these parameters are selected by computer. Slub version software is used for this purpose.

Types of slub yarn:

1. Pattern/regular slub yarn

2. Non-pattern/irregular slub yarn

3. Multi count slub yarn both pattern & non-pattern

Supplies of slub yarn attached machine:

1. Caipo- Italy

2. Pinter- Spain

3. Amsler- Switzerland
Production of slub yarn in Ring frame:

1. In the ring frame, there is a servo motor with slub gear and another with twist gear

2. Back and middle rollers get motion from the same gearing and the front rollers get

motion from separate gearing

3. Slub is produced by the speed variation of back and middle rollers

4. Break draft is always maintained properly, otherwise roving breakage will be created

5. Back roller speed will be increased continuously after a certain time. As a result more

material will be fed, whereas during that time the speed of front roller remaining

constant. So a thick place in the final yarn will be created after a certain time.

6. The controller controls the following-

- After how much time (millisecond) the speed of back roller will be increased

- How longer the increased speed will remain

- Amount of speed that to be increased

7. Twist gear is optional, the speed of front roller is fixed when twist gear is not used

8. Twist is controlled by changing the speed of front roller.

End uses: slub yarn is used in traditional fabrics such as upholstery, lace, curtains and

household fabrics in general. But it is becoming more popular in the production of denim.
