preparation example Construction

[0032] see Figure 1 to Figure 4 , a method for preparing an air-jet consolidation type antibacterial nonwoven fabric, comprising the following steps:

[0033] Fabrication steps of the fiber web: respectively prepare the upper coating fiber web 71, the upper elastic fiber web 1, the bamboo fiber web 2, the lower elastic fiber web 3, the dense fiber web 7, and the lower coating fiber web 72, the upper elastic fiber web The raw materials for making the net 1 and the lower elastic fiber net 3 include chemical fibers and hot-melt short fibers, and the content of the chemical fibers is greater than the hot-melt short fibers, and the raw materials for making the bamboo fiber net 2 include bamboo raw fibers;

[0034] Airflow injection consolidation step: first connect the air injection hole 42 in the air injection plate 41 with the air source 44 through the air intake pipe 43, and then set a suction box 45 directly below the air injection plate 41. At this time, the air injection pla...

Embodiment 1

[0056] see Figure 1 to Figure 4 , a method for preparing an air-jet consolidation type antibacterial nonwoven fabric, comprising the following steps:

[0057] Fabrication steps of the fiber web: respectively prepare the upper coating fiber web 71, the upper elastic fiber web 1, the bamboo fiber web 2, the lower elastic fiber web 3, the dense fiber web 7, and the lower coating fiber web 72 (preferably the upper elastic fiber web 72). The thickness of the fiber web 1 is less than or equal to the thickness of the lower elastic fiber web 3), the raw materials of the upper elastic fiber web 1 and the lower elastic fiber web 3 include chemical fibers and hot-melt short fibers, and the content of chemical fibers is greater than that of hot-melt fibers. Short fibers, the raw materials for making the bamboo fiber web 2 include bamboo fibers;

Embodiment 2

[0062] Basic content is the same as embodiment 1, the difference is:

[0063] The position near the upper elastic fiber net 1 on the bamboo fiber net 2 includes a plurality of inclined bamboo fibers 22, the bottom ends of the inclined bamboo fibers 22 are located in the bamboo fiber net 2, and the tops of the inclined bamboo fibers 22 are inserted into the upper elastic fibers. In the net 1, and the top of the inclined bamboo fiber 22 is fused with the chemical fibers and hot-melt short fibers in the upper elastic fiber net 1 located on its periphery to form an integral structure.

Abstract

The invention relates to a preparation method of an air injection consolidation antibacterial nonwoven fabric. The preparation method comprises the steps of preparing an upper coating fiber net, an upper elastic fiber net, a raw bamboo fiber net, a lower elastic fiber net, a dense fiber net and a lower coating fiber net separately, sequentially superimposing the raw bamboo fiber net, the lower elastic fiber net and the dense fiber net to form a superposition net, allowing the superposition net to pass through an air flow injection area to form a complex net, covering the top surface of the upper elastic fiber net with the bottom surface of the upper coating fiber net, covering the top surface of the complex net with the bottom surface of the upper elastic fiber net, covering the top surface of the lower coating fiber net with the bottom surface of the complex net to form a blank fabric, and sequentially drying and cooling the blank fabric to form the antibacterial nonwoven fabric. Theantibacterial nonwoven fabric is better in uniform dispersion effect, can enhance exertion of functions of raw bamboo fibers, and has low possibility of leakage and a better comfortable sensation.

Description

technical field [0001] The invention relates to a nonwoven fabric, which belongs to the field of nonwoven materials, in particular to a preparation method of an air-jet consolidation type antibacterial nonwoven fabric and an antibacterial nonwoven fabric, which are particularly suitable for improving the uniform dispersion effect of bamboo fibres, and are not easy to leak , and improve comfort. Background technique [0002] Mattresses, cushions, sofas, etc. are commonly used fiber products in people's lives. In daily use, these fiber products not only require good elasticity, but also have high requirements for antibacterial properties and deodorization. At present, the antibacterial treatment of mattresses, cushions, and sofas usually adopts the finishing method of spraying antibacterial agents, which is costly and difficult to maintain antibacterial properties. [0003] In the prior art, bamboo charcoal powder or bamboo charcoal particles are also used as filling material...
