Embodiment 1

[0046] The sheath fiber and the core fiber are both hollow crimped yarns (42T-12f) with a hollowness of 20% and a crimp radius of 20mm. The sheath fiber and the core fiber are fed separately through different feeding rollers, the feeding speed of the core fiber is 20m / min, and the feeding speed of the sheath fiber is 400m / min, that is, the filament length difference is 20 times. The flow rate of the air in the nozzle is set to 70 L / min, and the sheath fiber and the core fiber pass through the air nozzle to form a fluffy processed yarn.

[0047] After testing, the bulkiness of the obtained bulky processed yarn is 450inch 3 / 30g, the radius of the ring formed by the sheath fiber is 3.0mm, and the intersection points formed by the sheath fiber and the core fiber are 80 / cm.

Embodiment ２

[0049] The sheath fiber is made of hollow crimped yarn (60T-12f) with a hollowness of 25% and a crimp radius of 16mm, and the core fiber is hollow crimped yarn (42T-12f) with a hollowness of 20% and a crimp radius of 20mm. The sheath fiber and core fiber Feed separately through different feeding rollers, the feeding speed of the core fiber is 20m / min, and the feeding speed of the sheath fiber is 400m / min, that is, the filament length difference is 20 times. The flow rate of the air in the nozzle is set to 70 L / min, and the sheath fiber and the core fiber pass through the air nozzle to form a fluffy processed yarn.

[0050] After testing, the bulkiness of the obtained bulky processed yarn is 500inch 3 / 30g, the radius of the ring formed by the sheath fiber is 4.0mm, and the intersection points formed by the sheath fiber and the core fiber are 72 / cm.

Embodiment 3

[0052] The sheath fiber is hollow crimped yarn (84T-12f) with a hollowness of 35% and a crimp radius of 12mm, the core fiber is a hollow crimped yarn (42T-12f) with a hollowness of 20% and a crimp radius of 20mm, and the sheath fiber and core fiber Feed separately through different feeding rollers, the feeding speed of the core fiber is 20m / min, and the feeding speed of the sheath fiber is 400m / min, that is, the filament length difference is 20 times. The flow rate of the air in the nozzle is set to 70 L / min, and the sheath fiber and the core fiber pass through the air nozzle to form a fluffy processed yarn.

[0053] After testing, the bulkiness of the obtained bulky processed yarn is 700inch 3 / 30g, the radius of the ring formed by the sheath fiber is 6.8mm, and the intersection point formed by the sheath fiber and the core fiber is 55 / cm.

Abstract

The invention discloses a fluffy processing filament formed by polyester long fibers; the fluffy processing filament refers to the polyester processing filament containing hollow fibers; the filling power of the processing filament that measured by an IDFB method is 400inch 3 / 30g to 800inch 3 / 30g. The fluffy processing filament is excellent in fluffiness, soft in hand feeling, and can replace eider as fillers.

Description

technical field [0001] The present invention relates to a bulky processed yarn. Background technique [0002] Feathers of waterfowl such as goose down and duck down are usually used to fill duvets, sleeping bags and various cold-proof and warm-keeping products. The worldwide outbreak of bird flu has led to a sharp drop in the production of down and down, which has led to an increase in prices. At the same time, consumers also have doubts about the safety of down. If natural feathers are not washed enough, they will cause stench. Therefore, it is necessary to remove the dirt that causes stench in advance to keep the cleanliness of feathers. Moreover, there is also the problem that feather products such as feather quilts and feather jackets are difficult to wash. Chinese patent CN186187A discloses a kind of short-fiber imitation down cotton, but the bulkiness of the short-fiber filling cotton is not high, and there is a grainy feeling when the heat preservation material is m...
