What exactly does belly yarn mean? How is it formed?

Big-belly Yarns refers to the thick and thin yarn on one yarn in the finished woolen yarn, which is one of the appearance defects of the finished woolen yarn. The cross section is more than 3 times thicker than normal yarn, the length is 2-10cm, and it is in the shape of a jujube nucleus. Formation reason:

(1) Concentration of equal-length fibers without drafting to produce bundles;

(2) The fibers are sticky and complicated, and the carding and drafting cannot be opened;

(3) Insufficient front roller pressure;

(4) The middle friction force is too strong and the control force is too large;

(5) The top roller is too thin or cracked, loses elasticity, etc.
Application of belly yarn

Wearability: The fabric pattern woven by the yarn is protruding and has a strong three-dimensional effect.

Generally used for knitting and weaving. Such as: towels, sweaters, scarves and so on.

The proportion of the pot belly yarn in the fancy thread is getting larger and larger, and the belly is getting thicker and wider, and the application equipment is getting wider and wider. There are different styles of belly yarn produced by various equipments. For example, the cotton spinning frame is transformed to produce pot belly yarn. This kind of pot belly yarn is spun from the spinning frame last time without core thread and covering thread. The equipment transformation is very simple, and the electromagnetic clutch is used to stop the front roller gap, which can produce pot belly yarn. However, this kind of belly yarn should not be spun too thick, the average count is about 6 English (97tex), and the traveler is not easy to pass through. This kind of big belly yarn is mostly used to make wavy threads in fancy threads or to make covered threads of fancy threads by segment dyeing, and some are also used to make knot-shaped chenille threads.



Another example is the large belly yarn with core and covered yarn produced by the fancy twisting machine. This kind of large belly yarn is the easiest to produce. The roving is used to overfeed the middle and rear roller gaps to generate the large belly yarn, which is output through the front roller and the core. The threads are merged and then go into the hollow spindle and the covered thread is added. This kind of big belly yarn can be formed at one time, and the twist of the covered thread is basically consistent at the belly and the details. So this kind of big belly yarn feels rough and hard. If the decorative thread and the core thread have a certain chao feeding ratio, the corrugated belly yarn can also be formed at one time, but it cannot be spun too thick, generally around 1.5Nm.
