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 ...
