Description

1. Technical field

[0001] The invention relates to a production process of drawing short fibers and fibers produced by the process, belonging to the field of textiles. 2. Background technology

[0002] The price of high-quality white cashmere is high and the goods are in short supply, reaching a maximum of more than 800,000 per ton.
