Embodiment 1
[0019] Preparation of the fabric layer: Take polyester fibers with a weight percentage of 90:10 and fibers with a melting point of 100°C to open and mix them evenly to obtain fibers of a certain color and specification, and then transport the fibers to the carding machine through a material box. The fiber web is obtained by high-speed carding, and the fiber web is then passed through a cross-lapper to form a fiber web of 250 g / m2, and then the fiber web is transported to the needling machine, with a needling depth of 10mm and a needling speed of 3m / min. Acupuncture is carried out according to the conditions, and the fabric layer with an acupuncture density of 120 needles / square centimeter is obtained for subsequent use.
[0020] The preparation of the bottom material layer: take the polyester fiber with a weight percentage of 75:25 and the fiber with a melting point of 100°C to open and mix evenly to obtain fibers of a certain color and specification, and then transport the fib...
Embodiment 2
[0023] The preparation of the fabric layer: take the polyester fiber with a weight percentage of 92:8 and the fiber with a melting point of 110°C to open and mix evenly to obtain fibers of a certain color and specification, and then transport the fibers to the carding machine through the material box. The fiber web is obtained by high-speed carding, and the fiber web is then passed through a cross-lapper to form a fiber web of 430 g / m2, and then the fiber web is transported to the needling machine, with a needling depth of 13mm and a needling speed of 5m / min. Acupuncture is carried out according to the conditions, and the fabric layer with an acupuncture density of 500 needles / square centimeter is obtained for subsequent use.
[0024] Preparation of the bottom material layer: Take polyester fibers with a weight percentage of 45:55 and fibers with a melting point of 110°C to open and mix them evenly to obtain fibers of a certain color and specification, and then transport the fi...
Embodiment 3
[0027] The preparation of the fabric layer: take the polyester fiber with a weight percentage of 96:4 and the fiber with a melting point of 120°C to open and mix evenly to obtain fibers of a certain color and specification, and then transport the fibers to the carding machine through the material box. The fiber web is obtained by high-speed carding, and the fiber web is then passed through a cross-lapper to form a 600 g / m2 fiber web, and then the fiber web is transported to the needle loom with a needle punching depth of 12mm and a needle punching speed of 4m / min. Acupuncture is carried out according to the conditions, and the fabric layer with an acupuncture density of 300 needles / square centimeter is obtained for subsequent use.
[0028] The preparation of the bottom material layer: take the polyester fiber with a weight percentage of 55:45 and the fiber with a melting point of 120°C to open and mix evenly to obtain fibers of a certain color and specification, and then transp...
