Embodiment 1

[0029] refer to Figure 1 to Figure 5 , a kind of preparation method that contains the hygienic product of controllable local hydrophilic pure cotton nonwoven fabric, comprises following processing steps:

[0030] (1) Preparation of liquid-permeable surface layer: the liquid-permeable surface layer is composed of controllable local hydrophilic pure cotton non-woven fabric and hydrophobic non-woven fabrics arranged on both lateral sides thereof, and the controllable local hydrophilic pure cotton non-woven fabric The preparation steps of cotton non-woven fabric are:

[0031] a) Unwinding of pure cotton non-woven fabric: placing the pure cotton non-woven fabric on the unwinding mechanism 2 for unwinding;

[0032] b) For the polydimethylsiloxane hydrophobic oil agent 8 on the pure cotton non-woven fabric 1, the amount of liquid applied is controlled at 1 gsm, and the specific steps are: the pure cotton non-woven fabric 1 is continuously transported into the An embossing liquid f...

Embodiment 2

[0039] refer to Figure 7 And in the first embodiment, the groove on the protrusion 6 has two grooves with different depths, specifically the groove 62 and the groove 63 , and the depth of the groove 63 is twice that of the groove 62 .

[0040] In the present invention, the liquid amount is controlled at 0.5-3gsm, the height of the convex part is 5-15mm, and the distribution area of ​​the convex part on the embossing convex roller accounts for 20-50% of the total area outside the circumference of the embossing convex roller. The distance between two adjacent convex parts is at least 2 mm, the depth of the groove on the convex part is 1 / 5-1 / 3 of the height of the convex part, and the cross-sectional area of ​​the end of the convex part away from the embossing convex roller is less than 1 cm 2 , the grooves on the protrusions have more than two depths, and the object of the present invention can be achieved within the range of the above parameters.

Abstract

The invention relates to the field of hygiene products, and provides a hygiene product containing a controllable local hydrophilic pure cotton non-woven fabric and a preparation method of the hygieneproduct. The problems that a surface layer of a hygiene product in the prior art is strong in moist feeling, large in absorbed liquid retain amount and not dry and comfortable are solved. The preparation method comprises the steps of preparation of the surface layer, an absorbent body and a liquid-impermeable primer layer and integration of the obtained surface layer, the absorbent body and the liquid-impermeable primer layer into one body, and the surface layer is the controllable local hydrophilic pure cotton non-woven fabric; and the preparation steps of the controllable local hydrophilic pure cotton non-woven fabric are that (1) feeding of the pure cotton non-woven fabric is carried out, specifically, the pure cotton non-woven fabric is placed on a unwinding mechanism for feeding; (2)a hydrophobic oil agent is applied on the pure cotton non-woven fabric, theliquid applying amount is controlled at 0.5-3gsm; and (3) drying is carried out, and then the material is subjected to the next treatment process.

Description

technical field [0001] The invention relates to the field of hygienic products, in particular to a hygienic product containing controllable partially hydrophilic pure cotton non-woven fabric and a preparation method thereof. Background technique [0002] Sanitary products in the prior art generally include a liquid-permeable surface layer, an absorber, and a liquid-impermeable bottom layer that are sequentially stacked from top to bottom. The liquid-permeable surface layer usually includes a hydrophilic non-woven fabric and Hydrophobic non-woven fabrics on both sides in the horizontal direction. The hydrophilic non-woven fabrics are used to allow excretion to penetrate into the lower absorbent body. However, the traditional hydrophilic non-woven fabrics are generally pure cotton non-woven fabrics with hydrophilic effects throughout the entire piece. The non-woven fabric of this material can make the liquid seep down quickly, but due to the surface tension, the excretion is e...
