Production of Feather Yarn
Feather yarn is composed of core yarn and decorative yarn, and its production process is composed of knitting and cutting pile, that is, “one needle, one knife”. In order to obtain feather yarn with good quality and no lint, the following points should be paid attention to in the production process:
1. Choose the Right Raw Materials
Taking nylon feather yarn as an example, the raw materials must be imported nylon chips to prevent the occurrence of color flower and color difference.
2. Constant Temperature Treatment
The raw materials of Lun feather yarn should be treated with steam at a constant temperature, otherwise it will be curled and colored.
3. the Cutter Blade Should Be Replaced in Time
If the blade is not replaced in time, it will cause serious hair loss.
4. Finished Product Inspection
The feather yarn off the machine will have woolless yarn and oily yarn, which must be inspected by a special person, and the defective yarn will be picked out.
5. Hanking Process
The hanking skein must use a large-scale automatic shaking skein, to shake out a large pattern, and the frame length should be long, so as to prepare for the subsequent downfall, otherwise the downfall will not be poured out, and the loss will be serious. The skein must be less than 0.25kg, otherwise the nylon will flower.
6. Dyeing Control
