The use of needle cylinder rotation in production has a twisting effect on feather yarn. In order to eliminate internal twisting stress and prevent the absence of braided yarn, it is necessary to heat set the feather yarn that is removed from the machine, and different steam power settings can generally be used.
The steaming effect should not be too large, usually 0.2 kilograms per tube; Equipped with good breathable mesh and hollow wire spool; Choose appropriate yarn steaming according to the characteristics of fiber, low range shaping purpose, high impact yarn quality, energy waste, temperature and time. 1/6.5Nm bright nylon feather yarn is steamed at a preferred temperature of 80-85 ℃ for 30 minutes.
After steaming, there is no need for cooling, which directly affects the process of yarn shaking. On the one hand, we can release the water absorbed during steaming and the centrifugal airflow generated through yarn shaking. On the other hand, during yarn shaking, we can use a yarn guide to straighten our feathers. The rapid improvement of yarn quality cooling is beneficial for maintaining a beautiful appearance and protecting the quality of Chinese feather yarn.

Nylon fiber glass has low temperature, fast dyeing speed, and is easy to dye flowers. The weight of each yarn should be appropriate, usually 0.5 pounds per twist. The main defects of feather yarn are long and short hair, capillary and uneven, and light yarn without feathers. In order to prevent the collapse of feathers, things that should not be done with the bag, and loose bags can be directly sent to the dyeing factory for processing. For long-distance transportation, a large package can be used to restore elasticity after the disassembly execution upon arrival at the destination.
Feather yarn is made from nylon and viscose industry raw materials. Nylon has a fast dyeing speed and is not easy to dye evenly. It is required to slowly heat up and use blocking agents. Nylon, the dyeing properties of different batches from different companies are not separated from production. The same batch of different raw materials is packaged separately. The holding time should not be too long, otherwise the strength of the elastic yarn will decrease. The drying time and temperature should also be reasonably controlled to determine the characteristics of the fibers.
Feather yarn should be inclined along the yarn at a certain angle for development. When weaving and warping, attention should be paid to the basic consistency of the direction of the fuzz. If multiple batches of yarn are mixed and woven, they should be evenly distributed and used in alternating directions. It is best to use a rapier machine to feed multiple strands to people. Prevent defects in horizontal bars and stripes.
