Method for processing kapok fiber yarns

The invention discloses a method for processing kapok fiber yarns. The method comprises the following steps of: pretreating kapok fibers, and then spinning the kapok fibers, wherein the spinning comprises the following steps of: sequentially performing cotton catching, cotton mixing, cotton carding and opening, dust removal, cotton feeding, cotton carding and twice strip drawing on the kapok fibers, and the kapok fiber yarns can be obtained by directly performing friction spinning and winding or rotary cup spinning and winding on the drawn kapok fibers, or the kapok fiber yarns can be obtained by performing roving and then ring spinning and winding on the kapok fibers; treatment liquid in the pretreatment working procedure comprises the following components in parts by weight: 3-10 parts of corn starch, 2-10 parts of carboxymethylcellulose and 80-95 parts of water; and the pretreatment method comprises the steps of uniformly spraying the treatment liquid with the temperature of 50-80 DEG C on the kapok fibers which is 30-50 times heavier than the treatment liquid, then covering a thin film on the kapok fibers, and standing for 24 hours.
