preparation example Construction

[0031] see figure 1 - Figure 4 , a kind of preparation method of air-jet consolidation type high absorption nonwoven fabric, described preparation method comprises the following steps:

[0032] Fabrication steps of the fiber web: respectively prepare the upper elastic fiber web 1, the lower elastic fiber web 3 and the bamboo charcoal fiber web 2, 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 fiber is greater than hot-melt staple fiber, and the making raw material of described bamboo charcoal fiber web 2 comprises bamboo charcoal fiber;

[0033] 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 plate 41, suction The area sandwiched between the ...

Embodiment 1

[0052] see Figure 1 to Figure 4 , a method for preparing an air-jet consolidation type high-adsorption nonwoven fabric, comprising the following steps:

[0053] Fabrication steps of the fiber web: respectively prepare the upper elastic fiber web 1, the lower elastic fiber web 3 and the bamboo charcoal fiber web 2 (preferably the thickness of the upper elastic fiber web 1 is smaller than the lower elastic fiber web 3), the upper elastic fiber web 1 , the raw material for making of lower elastic fiber web 3 comprises chemical fiber and hot-melt short fiber, and the content of chemical fiber is greater than hot-melt short fiber, and the raw material for making of described bamboo charcoal fiber net 2 comprises bamboo charcoal fiber;

[0054] 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 th...

Embodiment 2

[0058] Basic content is the same as embodiment 1, the difference is:

[0059] The bamboo charcoal fiber net 2 includes a plurality of inclined bamboo charcoal fibers 22 in the position near the upper elastic fiber web 1, the bottom end of the inclined bamboo charcoal fibers 22 is located in the bamboo charcoal fiber net 2, and the top of the inclined bamboo charcoal fibers 22 is inserted into the upper elastic fiber. In the net 1, the top of the inclined bamboo charcoal fiber 22 is fused with the chemical fiber and hot-melt short fiber 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-jetting solidification-type high-adsorbability non-woven fabric. The method comprises the steps that firstly, an upper elastic fiber mesh, a lower elastic fiber mesh and a bamboo charcoal fiber mesh are prepared separately, then the bamboo charcoal fiber mesh covers the top face of the lower elastic fiber mesh for obtaining an overlaying mesh, the overlaying mesh is placed on a conveying curtain, and the conveying curtain is of a grid structure; the conveying curtain drives the overlaying mesh to move forward in the horizontal direction until the overlaying mesh passes through an airflow jetting area so as to obtain a composite mesh, in the process that the overlaying mesh passes through the airflow jetting area, air-jetting holes jetairflow downwards, and the airflow passes through the overlaying mesh and the conveying curtain in sequence and then is jetted into an air suction box; the upper elastic fiber mesh covers the top face of the composite mesh for obtaining a gray fabric, and the gray fabric is dried and cooled in sequence for obtaining the high-adsorbability non-woven fabric. According to the preparation method, theeven dispersion effect is good, exertion of the function of a bamboo charcoal fiber can be improved, leakage is not easily caused, and the comfort feeling is good.

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 high-adsorption nonwoven fabric and a high-adsorption nonwoven fabric, which are particularly suitable for improving the uniform dispersion effect of bamboo charcoal fibers, and Less prone to leaks and improves comfort. Background technique [0002] Mattresses, cushions, sofas, etc. are commonly used fiber products in people's daily life. In addition to good elasticity, these fiber products also have high requirements for adsorption of harmful gases, deodorization and antibacterial properties during daily use. For this reason, adopt bamboo charcoal powder or bamboo charcoal granule as filling material in the prior art, develop bamboo charcoal products, as bamboo charcoal mattress, bamboo charcoal cushion etc., but all have certain defect, as: bamboo charcoal powder easily leaks and causes p...
