Embodiment 1

[0039] In the first step, weighing, opening and mixing, pre-forming, carding, air-forming, and acupuncture are carried out according to the composition of 100% PP fibers to obtain the bonding layer 2, needle board cloth in the acupuncture process The needle density is 1000 pieces / m, the acupuncture frequency is 1500 times / min, and the speed is 2 m / min.

[0040] The second step: according to the ratio of 20% ES fiber and 60% flax fiber, carry out weighing, opening and mixing, pre-forming, carding, and air-forming to prepare upper layer 1 and lower layer 3, wherein pre-forming, carding, The speed of the air-laid process is 5m / min, and the thickness of the upper and lower layers is 3cm respectively;

[0041] The third step: the upper layer 1 and the lower layer 3 prepared by the adhesive layer 2 prepared in step S01 and step S02 according to figure 1 Lay together in the order shown, and then enter the oven together, cold rolling, cooling, cutting, inspection and packaging, the o...

Embodiment 2

[0045] In the first step, according to the composition of 80% PE / PET sheath-core fiber and 20% vinylon fiber, carry out weighing, opening and mixing, pre-forming, carding, air-laying, and needle-punching to obtain the adhesive layer 2 , the density of needle board needles in the acupuncture process is 3000 pieces / m, the acupuncture frequency is 1000 times / min, and the speed is 10 m / min;

[0046] The second step: according to the ratio of 30% ES fiber, 10% jute fiber, 50% coconut fiber, 10% bamboo charcoal fiber, weighing, opening and mixing, pre-forming, carding, air-laid to make the upper layer 1. The lower layer 3, wherein the speed of the pre-forming, carding, and air-laying processes is 10m / min, and the thickness of the upper and lower layers is 2.5cm respectively;

[0047] The third step: the upper layer 1 and the lower layer 3 prepared by the adhesive layer 2 prepared in step S01 and step S02 according to figure 1 Lay together in the order shown, and then enter the oven...

Embodiment 3

[0051] In the first step, according to the composition of 60% 4080 fiber, 20% polyester fiber and 20% nylon fiber, the bonding layer is obtained by weighing, opening and mixing, pre-forming, carding, air-laid and needle punching 2. The bonding layer adopts the needle board cloth needle density of 5000 pieces / m in the acupuncture process, the acupuncture frequency is 100 times / min, and the speed is 18 m / min;

Abstract

The invention discloses a natural fiber composite plate, which comprises an upper layer, a lower layer and a bonding layer for bonding the upper layer and the lower layer, wherein the upper layer and the lower layer are nonwoven layers comprising the following components: 5 to 50 percent of low melting point fibers and 5 to 65 percent of jute fibers; and the bonding layer is a nonwoven layer comprising 50 to 100 percent of low melting point fibers. The invention also discloses a method for manufacturing the natural fiber composite plate, which comprises the following steps of: respectively preparing various layers, namely the upper layer, the lower layer and the bonding layer; and sequentially spreading the layers, drying in an oven, performing cold rolling, cooling, cutting, checking and packaging to obtain the natural fiber composite plate. By the natural fiber composite plate and the method for manufacturing the natural fiber composite plate, the problem that the conventional mattress is easily moulded with damp, goes bad due to moths and is easily layered is solved.

Description

technical field [0001] The invention relates to a composite board material, in particular to a natural fiber composite board prepared from hemp fiber and a preparation method thereof. The natural fiber composite board of the invention can be used as a mattress filling material, and of course can be used for other purposes. Background technique [0002] Coir palm mattress commonly used at present is to adopt palm fiber as filling material, and coconut palm mattress will use a large amount of glue to bond during preparation, if long-term use can cause harm to human health. Moreover, the coconut palm mattress is not only easy to be damp and moldy, or worms to deteriorate, easy to collapse, easy to break, but also hard and poor in elasticity. Its use range is narrow, and it is mostly suitable for hard mattresses. [0003] The patent document whose notification number is CN201139289Y discloses a health-care mattress, including a mattress body and a jute fiber fabric covering laye...
