The invention discloses blended
yarn deeply developed from silkworms and a
spinning process of the blended
yarn. The blended
yarn comprises a yarn body, wherein the yarn body is hollow yarn and comprises a hollow inner core layer, a
sericin film layer and a winding
skin layer which are sequentially arranged from inside to outside, the hollow inner core layer is made of mulberry
bark fibers, the mulberry
bark fibers are spirally wound outside a
hollow core hole of the yarn body, the
sericin film layer is formed by
coating sericin outside the hollow inner core layer to form a film layer structure, the winding
skin layer adopts winding filaments, and the winding filaments are spirally wound outside the sericin film layer to form an outer wrapping structure. According to the blended yarn deeply developed from the silkworms and the
spinning process of the blended yarn, the silkworm industry is deeply developed, resources are fully utilized, and the mulberry fibers, the sericin,
pupa proteinviscose filaments or spun silk are used for
spinning the novel blended yarn; and the blended yarn is low in cost, high in
yarn strength, soft and smooth in touch, washable, good in shrink-proof and crease-resistant performance, good in water absorption and air permeability and excellent in comprehensive performance.
