Embodiment 1
[0050] Prepare PET short-fiber raw cotton (fineness 3 den, length 51mm), and first carry out the cotton opening project in the non-woven production line (the opening amount is 200kg / min). Then, the fiber raw cotton after opening is transported to the carding machine for carding process, and the non-woven cotton web is obtained.
[0051] The non-woven cotton net is stacked to form a net cotton with a height of 10cm, a width of 200cm, and a unit weight of 250g / m 2 The non-woven cotton net is put into an elastic net layer before needle rolling. The material of this elastic mesh layer is TPU, and the diameter of its first directional fiber and the second directional fiber are all 0.08mm, and the intersection angle of the first directional fiber and the second directional fiber is 30 ° (and 150 °), mostly The distance between adjacent two of a first oriented fiber and a plurality of second oriented fibers is 5 mm.
[0052] Continue needle rolling the non-woven fabric cotton net, ...
Embodiment 2
[0056] Prepare split-type microfiber raw cotton (fineness 4.5 denier, length 51mm), and firstly carry out the cotton opening process in the non-woven production line (the opening amount is 280kg / min). Then, the fiber raw cotton after opening is transported to the carding machine for carding process, and the non-woven cotton web is obtained.
[0057] The non-woven cotton net is stacked to form a net cotton with a height of 13cm, a width of 200cm, and a unit weight of 320g / m 2 The non-woven cotton net is put into an elastic net layer before needle rolling. The material of this elastic mesh layer is TPEE, and the diameter of its first directional fiber and the second directional fiber are all 0.12mm, and the intersection angle of the first directional fiber and the second directional fiber is 60 ° (and 120 °), mostly The distance between adjacent two of a first oriented fiber and a plurality of second oriented fibers is 5 mm.

Embodiment 3
[0062] To prepare split-type microfiber raw cotton (fineness 4 den, length 51mm), firstly carry out the cotton opening project in the non-woven production line (the opening amount is 150kg / min). Then, the fiber raw cotton after opening is transported to the carding machine for carding process, and the non-woven cotton web is obtained.
[0063] The non-woven cotton net is stacked to form a net cotton with a height of 9cm, a width of 200cm, and a unit weight of 200g / m 2The non-woven cotton net is put into an elastic net layer before needle rolling. The material of this elastic mesh layer is TPO, and the diameter of its first directional fiber and second directional fiber is 0.03mm, and the intersection angle of first directional fiber and second directional fiber is 90 °, and a plurality of first directional fibers The distance between adjacent two of the fibers and the plurality of second oriented fibers is 5 mm.
[0064] Continue pinning the non-woven cotton net. After six p...
