Example 3
The present embodiment provides a method for preparing a tampon having a cotton cover layer, so as to prepare the tampon having a cotton cover layer described in example 1, which is substantially the same as the steps in example 1, except that: step S2 in embodiment 1 is replaced by step S2' described below.
Specifically, step S2' is: and stacking the cotton fiber sheets and the thermoplastic resin fiber sheets and compounding by a spunlace process to form the double-sided non-woven fabric.
Preferably, in step S2, the water pressure is not less than 50kg when the cotton fiber sheet and the thermoplastic resin fiber sheet are combined to form the double-sided nonwoven fabric by the spunlace process.
The spunlace process is characterized in that a plurality of strands of fine water jet streams generated at high pressure are used for jetting the fiber web, after the water jet streams penetrate through the fiber web, the fine water jet streams are rebounded by a supporting net curtain, and the fiber web is inserted again, so that fibers in the fiber web are displaced, inserted, tangled and cohered under the hydraulic action of high-speed water jet streams inserted in different directions, and the fiber web is reinforced.
In the embodiment, the spunlace process is adopted to spray the micro water flow of not less than 50kg onto the stacked cotton fiber sheets and the thermoplastic resin fiber sheets, the cotton fiber sheets and the thermoplastic resin fiber sheets are substantially of net structures, and the fibers of the two layers of net structure fiber sheets are mutually entangled under the action of water pressure to have certain strength, so that the fiber sheets are compounded. Of course, in the preparation method in this embodiment, after the completion of the spunlace process, the double-sided nonwoven fabric needs to be dried before the next process is performed.
The rest of the preparation method in this embodiment is the same as that in embodiment 2, and for related parts, reference is made to embodiment 2, which is not repeated herein.
It should be understood that the above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the present invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
