Embodiment 1

[0039] Such as figure 1 As shown, the production of oil-absorbing down flakes:

[0040] 1. The down material is pinnae, and the mixing ratio is generally: the down (pinne) content of mixed material B is 70%, ES hot-melt fiber 20%; the down content of mixed material A is 20%, polyester 40%, ES hot-melt fiber 40%. 2. Process flow such as image 3 as shown,

[0041] 3. Carding adopts a cover-type carding machine. The raw material feeding box of the carding machine is divided into 5 grids along the machine width (1.5m), that is, 5 small raw material feeding boxes are formed, and the width of 1 and 5 boxes is 0.2 m, the width of No. 2 box in the middle is 0.9m, so the blending ratio of the carded fiber web along the width direction of the machine is ABA, in which the width of the fiber web of part B is 0.9m, and the fiber web of part A on both sides is 0.3m .

[0042] 4. The netting adopts cross-laying netting, and the fiber netting after laying up has a sandwich structure, wh...

Embodiment 2

[0046] Such as figure 2 As shown, the production of down flakes for winter protection:

[0047] 1. The down material is high-grade down, and the mixing ratio is generally: the down (high-grade) content of mixed material C is 70%, 4080 hot-melt fiber 20%; the down content of mixed material B is 20%, polyester 40%, 4080 hot-melt Fiber 40%; down content of mixed raw material A is 0%, polyester 60%, ES heat-melt fiber 40%.

[0048] 2. Process flow such as Figure 4 shown.

[0049] 3. Carding adopts a flat carding machine. The raw material feeding box of the carding machine is divided into 5 grids along the machine width (1.5m), that is, 5 small raw material feeding boxes are formed, and the width of 1 and 5 boxes is 0.1m. , Boxes 2 and 4 have a width of 0.20m, and box No. 3 in the middle has a width of 0.9m. The raw material distribution of the carded fiber web along the width direction of the machine is ABCBA, wherein the width of the fiber web in part C is 0.9, and the part ...

Abstract

The invention discloses a processing method for a multilayer composite sized down feather flocculus, and the method comprises the following steps of: mixing cotton, namely mixing 10-70wt% of down feather fiber with 90-30wt% of low-melting-point fiber by virtue of a mixer so as to respectively obtain a high-down-feather-content mixture and a low-down-feather-content mixture; and opening, carding, lapping, carrying out acupuncture reinforcing, and carrying out hot melting, bonding and reinforcing. An acupuncture reinforcing manner is adopted, so that the bulking intensity of a fiber mesh is effectively controlled, and entanglement between fibers is enhanced, thus the down feather is effectively controlled, and play of flying feather and the down feather is reduced; and multi-consolidation is carried out by adopting a method that acupuncture is firstly carried out and then hot melting is carried out, so that control over the down feather is effectively improved, and the stability of the down feather flocculus is improved.

Description

technical field [0001] The invention designs a method for making qualitative down wadding, in particular relates to a method for making a composite down wadding formed by carding and stacking a variety of fibers. Background technique [0002] Down is the fluff that grows in the abdomen of animals such as geese and ducks, and is called feathers in flakes. The down described in this patent comprises the feather silk obtained by opening the feather. my country's eiderdown production accounts for about 70% of the world's total, and has good thermal insulation properties. As a thermal insulation material, it has been widely used in various clothing and bedding fillers. [0003] Down is a kind of animal protein fiber, which has higher thermal insulation than cotton (vegetable cellulose), and the down ball-shaped fiber is densely covered with tens of thousands of small triangular pores, which can shrink and expand with temperature changes, produce temperature regulation function, ...
