Embodiment 1-21

[0055] As described in Table 1, the raw materials and raw material weight ratios of Examples 1-21 were selected.

[0056] Table 1, the raw material of embodiment 1-21 and raw material weight ratio

[0057]

[0058] Make the three-layer sandwich type composite down wadding sheet of embodiment 1-21 according to the following steps:

[0059] see figure 1 and figure 2 As shown, step (1): the animal and plant fibers and low-melting point fibers are mixed, carded, and laid at the laying point 1 to make continuous lower layer flakes, which are sent to the Laying 2 places; After mixing, opening and spreading the animal and plant fibers and low-melting point fibers, the down fibers are spread, and the middle layer flakes are made by air-laid netting, which is also transported by the second conveyor belt. Sent to Laying 2; Animal and plant fibers and low melting point fibers are blended, carded, and made into continuous upper flakes at Laying 2. Step (2): The stacked lower layer...

Abstract

The invention relates to a three-layer sandwiched composite eiderdown flake and a manufacturing method thereof. The three-layer sandwiched composite eiderdown flake comprises a lower flake, a middle flake and an upper flake; the upper flake comprises animal and plant fibers and low-melting fibers; the middle flake comprises eiderdown fibers, animal and plant fibers and low-melting fibers; the lower flake comprises animal and plant fibers and low-melting fibers; and the upper flake, the middle flake and the lower flake are thermally fused together. The manufacturing method comprises the following steps: manufacturing the lower flake by using the animal and plant fibers and the low-melting fibers by cotton blending, cotton carding and lapping; manufacturing the middle flake by cotton blending, opening and lapping of the animal and plant fibers and the low-melting fibers, paving of the eiderdown fibers and air laying, and paving the middle flake above the lower flake; manufacturing the upper flake by using the animal and plant fibers and the low-melting fibers by cotton blending, cotton carding and lapping, and paving the lower flake above the middle flake; and thermally fusing the lower flake, the middle flake and the upper flake together.

Description

technical field [0001] The invention relates to a composite down wadding sheet and a manufacturing method thereof, in particular to a three-layer sandwich composite down wadding sheet and a manufacturing method thereof. Background technique [0002] Down comes from waterfowl such as geese and ducks. As a high-grade cold-proof and warm-keeping material, it has been widely used as filling material for clothing and bedding. Its products are light, soft, warm and comfortable. [0003] Down is elastic, light, fluffy and soft, and a certain gap can be formed between feathers and barbules, containing still air, so the thermal conductivity is low and it has good thermal insulation performance. At the same time, as a kind of natural material, its products are very easy to be favored by consumers. [0004] Down is used as a filler to make down jackets, duvets, etc. This kind of down products has the advantages of lightness, softness and good warmth retention. However, this kind of d...
