Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the service life and comfort of the mattress are limited by the amount of low-melting fiber and hemp fiber added therein, resulting in the contradiction between strength and air permeability, and at the same time solve the problems caused by the thickness of this mattress. The delamination problem, thereby can provide a kind of promptly antibacterial property, not easy to infestation, air permeability, hygroscopicity and hygroscopicity are strong, and durable, air permeability is good, the composite environmental protection mat that is not easy to delaminate, the present invention also Provide the preparation method of the composite environmental protection pad, the preparation method can further improve the delamination problem

Embodiment 1

[0044] In the first step, each component is weighed according to the required ratio, opened and mixed, pre-laid, carded, air-laid, and needle-punched to prepare the upper surface layer 4 and the lower surface layer 5 respectively. Layer 3, wherein the non-woven layer of the upper surface layer 4 and the lower surface layer 5 adopts 10% PP fiber and 90% elastic chemical fiber, and the bonding layer 3 adopts 100% PP fiber; 1000 pieces / m, acupuncture frequency 1500 times / min, speed 2m / min.

[0045] The second step: according to the ratio of 20% ES fiber and 80% flax fiber, weighing, opening and mixing, pre-forming, carding, and air-forming make the first intermediate layer 1 and the second intermediate layer 2, wherein The speed of pre-forming, carding and air-forming process is 5m / min,

[0046] The third step: the first intermediate layer 1 and the second intermediate layer 2 prepared by the nonwoven layer prepared in step S01, the bonding layer 3 and step S02 according to fig...

Embodiment 2

[0050] In the first step, each component is weighed according to the required ratio, opened and mixed, pre-laid, carded, air-laid, and needle-punched to prepare the upper surface layer 4 and the lower surface layer 5 respectively. Layer 3, wherein the non-woven layer used in the upper surface layer 4 and the lower surface layer 5 adopts 40% PE / PET sheath-core fiber and 60% jute fiber, and the bonding layer 3 adopts 100% PE / PET sheath-core fiber; acupuncture process The density of needle board needles in the needle board is 3000 pieces / m, the needling frequency is 1000 times / min, and the speed is 10 m / min;

[0051] The second step: weighing according to the ratio of 30% ES fiber, 20% jute fiber and 50% coconut palm fiber, opening and mixing, pre-forming, carding, and air-laid to prepare the first middle layer 1, the second Two intermediate layers 2, wherein the speed of pre-forming, carding and air-forming process is 10m / min;

[0052] The third step: the first intermediate lay...

Embodiment 3

[0056] In the first step, each component is weighed according to the required ratio, opened and mixed, pre-laid, carded, air-laid, and needle-punched to prepare the non-woven layer and the adhesive layer of the upper and lower surface layers respectively, among which the non-woven The layer uses 25% 4080 fiber, 45% elastic chemical fiber, 30% kenaf fiber, and the bonding layer uses 80% 4080 fiber and 20 polyester fiber; the needle cloth needle density in the needle punching process is 5000 pieces / m , the acupuncture frequency is 100 times / min, and the speed is 18 m / min;

[0057] Step 2: According to the ratio of 40% PE / PET sheath-core fiber, 50% sisal fiber, and 10% palm fiber, carry out weighing, opening and mixing, pre-forming, carding, and air-laying to make the first intermediate Layer, the second intermediate layer, wherein the speed of pre-forming, carding, air-laid process is 18m / min;

[0058] The third step: Lay the non-woven layer prepared by step S01, the bonding la...

Abstract

The invention discloses a composite environmental-friendly cushion which comprises a middle layer and upper and lower surface layers. The middle layer comprises a first middle layer, a second middle layer and a bonding layer. The upper and lower surface layers are non-woven layers comprising 5 percent to 50 percent of low melting point fibers. The first and second middle layers are non-woven layers which respectively comprise the following components: bastose and 5 percent to 50 percent of low melting point fibers. The bonding layer mainly consists of the low melting point fibers. In the whole composite environmental-friendly cushion, the content of the bastose is within the range of 5 percent to 65 percent. The invention also discloses a preparation method of the composite environmental-friendly cushion, which comprises the following steps of: respectively preparing the middle layer, the upper and lower surface layer and the bonding layer; then sequentially paving the layers; and preparing the composite environmental-friendly cushion by processes of processing by an oven, cold milling, cooling, cutting, inspecting and packaging. Due to the adoption of the composite environmental-friendly cushion and the preparation method thereof, which are disclosed by the invention, the problem that the existing mattress is easy to affect with damp, mildew, breed worms and deteriorate, is easy to layer and has poor air permeability is solved.

Description

technical field [0001] The invention relates to a composite pad, in particular to a composite environmental protection pad prepared from hemp fiber and a preparation method thereof. The composite environmental protection pad of the invention can be used as a mattress or 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 layer wrapped outside the mattress body, w...
