摘要

In the manufacturing method of the covering company, after supplying the polyurethane filament of 18 to 20d and stretching at a draft ratio of 2.0 to 3.0, twisted 20 to 30d synthetic fiber filament to 1,000 to 1,500 per 1m to the polyurethane filament The present invention relates to a method for manufacturing a three-time covering yarn for stretch teaching fabrics, which is covered with a water channel.
