Embodiment 1

[0055] Such as figure 1 and figure 2 As shown, a black sanitary napkin is provided in the embodiment of the present invention. The black sanitary napkin includes a sanitary napkin body, and the sanitary napkin body includes a surface non-woven fabric layer 1, an absorbent core 2, a bottom layer of anti-woven fabric from top to bottom. Permeable membrane 3; the surface layer of non-woven fabric comprises an intermediate sheet 11, retaining wall 12 and side wings 13; 3 Cooperate and completely cover the absorbent core 2; the side wings 13 are arranged on both sides of the surface non-woven fabric layer 1 for fixing the sanitary napkin body; both sides of the middle sheet are provided with the The retaining wall 12, the retaining wall 12 is used to block the side leakage of the absorbents by the intermediate sheet 11 or the absorbent core 2; the side wings 13 and the intermediate sheet 11 are fixedly connected by the retaining wall 12; the surface layer has no Both the woven f...

Embodiment 2

[0070] This embodiment discloses a specific material and preparation method of the surface non-woven fabric layer in the black sanitary napkin.

[0071] 30wt% of black polylactic acid fiber and 70wt% of black viscose fiber are used as raw material fibers to be prepared through a hydroentangling process. The spunlace process includes the following steps. The raw material fibers are opened, mixed, and carded to form a fiber web layer with a thickness of 1.0-1.2 mm, and then the fiber web layer is sprayed with high-pressure and high-speed fine water flow to form a certain thickness. and strong non-woven fabrics, and perform water-repellent treatment on non-woven fabrics. In the spunlace process, the FLLBG-250 spunlace machine is used, the number of spunlace passes is 6, and the number of spunlace nozzles is 6 groups. There are six spunlaces in the spunlace step; the pressure of the first spunlace head is 40bar; the pressure of the second spunlace head is 35bar; the pressure of t...

Embodiment 3

[0076] This embodiment discloses a specific surface non-woven fabric layer material in a black sanitary napkin and a preparation method thereof.

[0077]Using 50wt% black polylactic acid fiber and 50wt% binchotan fiber as raw material fibers, it is prepared through a hydroentangling process. The spunlace process includes the following steps: raw material fibers are opened, mixed, and carded to form a fiber web layer with a thickness of 1.0 to 1.5 mm, and then the fiber web layer is sprayed with high-pressure and high-speed fine water flow to form a certain thickness. and strong non-woven fabrics, and perform water-repellent treatment on non-woven fabrics. In the spunlace process, the FLLBG-250 spunlace machine is used, the number of spunlace passes is 6, and the number of spunlace nozzles is 6 groups. There are six spunlaces in the spunlace step; the pressure of the first spunlace head is 42bar; the pressure of the second spunlace head is 38bar; the pressure of the third spun...

Abstract

The invention provides a black sanitary towel. The black sanitary towel comprises a sanitary towel body, and the sanitary towel body comprises a surface non-woven fabric layer, an absorption core anda bottom impermeable membrane from top to bottom in sequence; the surface non-woven fabric layer comprises a middle sheet, retaining walls and side wings; the middle sheet is arranged in the middle ofthe surface non-woven fabric layer and used for cooperating with the bottom impermeable membrane and completely wrapping the absorption core; the side wings are arranged at the two sides of the surface non-woven fabric layer and used for fixing the sanitary towel body; the retaining walls are arranged at the two sides of the middle sheet and used for preventing an absorbed material which is absorbed by the middle sheet or the middle core from leaking from the sides; the side wings are fixedly connected with the middle sheet through partial retaining walls; the surface non-woven layer and thebottom impermeable membrane are both black. The black sanitary towel can meet the basic requirement of sanitary towels and have the advantages of bacterial inhibition, odor removal, moisture absorption and ventilation, soft and comfortable performance and complete degradation.

Description

technical field [0001] The invention relates to a sanitary napkin, in particular to a black sanitary napkin. Background technique [0002] Traditional sanitary napkins are made of chemical fiber or cotton top layer, which inevitably has the trouble of being plagued by bacteria. A World Health Organization official said that 50% of gynecological patients in the world have used unclean sanitary products. In my country, a large-scale statistical result in 1996 showed that 38% of women who used unclean sanitary napkins fell ill. [0003] Before industrial mass production, polylactic acid materials were mainly used as medical products such as non-removable surgical sutures and skeleton materials for controlled release drugs. Polylactic acid has natural antibacterial properties without adding any drugs. [0004] Chinese patent CN200810004422.0 discloses a corn polylactic acid fiber sanitary napkin, which is composed of polylactic acid fiber spunlace non-woven fabric, a woven ab...
