Whether it is bulk yarn or solid yarn, it is widely used in the textile industry. The bulked yarn contains shrinkable acrylic fiber, which shrinks when it encounters heat and humidity during the dyeing or bulking process, making the surface of the yarn bulky. It is mostly used in artificial fur or wool knitting sweaters. The solid yarn does not contain shrinkage. Sexual ingredients, mostly used under woven fabrics.

Bulked yarn will appear zigzag after dyeing and heating, and the surface of the yarn will show a bulking effect, while solid yarn will not be deformed after heating or dyeing.

So how does the bulked yarn achieve the effect?

The bulked yarn is first blended into yarn by two fibers with different shrinkage rates, and then the yarn is treated in steam or hot air or boiling water. At this time, the fiber with high shrinkage rate shrinks greatly and is located in the center of the yarn. , and the mixed low-shrinkage fibers, due to their small shrinkage, are extruded on the surface of the yarn to form a circle, thereby obtaining a fluffy, plump and elastic bulked yarn.
