Example Embodiment
[0043] Example 1
[0044] In the first step, the components are weighed in proportion, opened and mixed, pre-laid, carded, air-laid, and needle punched to prepare the non-woven layer of the upper surface layer 1 and the bonding layer 3 respectively. The upper surface layer The non-woven layer of 1 is made of 10% PP fiber, 90% of elastic chemical fiber, and the bonding layer 3 is made of 100% PP fiber. The needle board cloth needle density in the needle punching process is 1000 pieces / m, and the needling frequency is 1500 Times / minute, the speed is 2 meters / minute.
[0045] The second step: according to the proportion of 20% ES fiber, 70% flax fiber, 10% bamboo charcoal fiber, weigh, open and mix, pre-web, card, air-laid first middle layer 2, second middle Layer 4, in which the speed of the pre-netting, carding, and air-laying processes is 5m / min, and the thickness of the first intermediate layer 2 and the second intermediate layer 4 are 3cm respectively;
[0046] The third step: th...

[0049] Example 2:
[0050] In the first step, the components are weighed, opened and mixed, pre-laid, carded, air-laid, and needle punched in proportion to prepare the non-woven layer of the upper surface layer 1, wherein the non-woven layer of the upper surface layer 1 The ratio of 40% PE / PET sheath-core fiber and 60% jute fiber is adopted, and the bonding layer 3 uses 80% PE / PET sheath-core fiber and 20% polyester fiber; the needle board cloth needle density in the needle punching process is 3000 pieces / m, acupuncture frequency is 1000 times / min, speed is 10m / min;
[0051] The second step: according to the ratio of 30% ES fiber, 20% jute fiber, 50% coconut palm fiber, weigh, open and mix, pre-web, card, air-laid to obtain the first intermediate layer 2, the second The second intermediate layer 4, in which the speed of the pre-web, carding, and air-laid processes is 10m / min, and the thickness of the first intermediate layer 2 and the second intermediate layer 4 are 2.5cm respecti...
Example Embodiment
[0055] Example 3:
[0056] In the first step, the components are weighed, opened and mixed, pre-laid, carded, air-laid, and needle punched in proportion to obtain the non-woven layer of the lower layer 5 and the bonding layer 3 respectively. The non-woven layer of 5 uses 25% 4080 fiber, 45% elastic chemical fiber, 30% kenaf fiber, and the bonding layer uses 60% 4080 fiber, 30% polyester fiber and 10% bamboo charcoal fiber; needle punching process The needle board density in the needle board is 5000 pieces / meter, the needle punching frequency is 100 times / minute, and the speed is 18 meters / minute;
[0057] Step 2: According to the ratio of 40% PE / PET sheath-core fiber, 50% sisal fiber, and 10% brown fiber, the first intermediate is obtained by weighing, opening and mixing, pre-laid, carding, and air-laid. Layer 2, the second intermediate layer 4, wherein the speed of the pre-netting, carding, and air-laid processes is 18m / min, and the thickness of the first intermediate layer 2 and...
