Embodiment 1

[0062] Manufacture of lining materials (perforation of hydrophobic nonwovens and lamination of absorbent nonwovens)

[0063] The weight of hydrophobic non-woven fabric is 13g / m 2 polypropylene spunbond nonwoven fabric.

[0064] Pin flushing takes place via pin rollers.

[0065] As the pin roll, a pin roll having a pin body area accounting for 42% of the bottom surface area of ​​the pin roll was used.

[0066] The hydrophobic perforated non-woven fabric is ultrasonically bonded with a weight of 20g / m 2 Hydrophilic air-treated nonwoven embossed laminate.

[0067] The lamination embossing roll bonding pattern used a diamond wire pattern with a length of four sides of 7 mm and a line width of 1 mm.

[0068] Bonding of hydrophobic perforated nonwovens and hydrophilic nonwovens along a diamond linear bonding pattern.

[0069] (Test result of Example 1)

[0070] Linting of perforated nonwovens was compared before and after embossing lamination.

[0071] When rubbing by hand, i...

Embodiment 2

[0073] Except that in Example 1, the hydrophobic perforated nonwoven laminated paper towel (21g / m 2 ) and weight 20g / m 2 Except for the non-woven fabric of the hydrophilic ventilation treatment, the same method as in Example 1 was used to manufacture a non-woven lining.

[0074] The test result is similar to Example 1.

Embodiment 3

[0076] Manufacturing of diapers

[0077] Using the nonwoven liner of Example 1, disposable diapers were manufactured.

Abstract

Provided is a top sheet for a disposable diaper and sanitary pad which is prepared by manufacturing a perforated hydrophobic nonwoven having a weight of 25g / m2 or less, and embossing / laminating the nonwoven and an absorbent material through thermal adhesion or ultrasonic adhesion. Conventional hydrophilic nonwovens commonly used as top sheets for disposable diapers and sanitary pads have sufferedfrom the major shortcoming that they cause skin irritation. Unlike conventional hydrophilic nonwovens, the novel perforated hydrophobic nonwoven used as the top sheet for a diaper according to the present invention are provided with decreased skin irritation and improved skin friendliness and dryness. The process for manufacturing a disposable diaper or sanitary pad using a perforated nonwoven alone may cause problems.; The nonwoven top sheet of the present invention has functions and roles to overcome such problems caused by using the perforated nonwoven alone. Furthermore, less lint is produced on the surface of the nonwoven top sheet during the process of embossing / laminating the perforated hydrophobic nonwoven having a weight of 25g / m2 or less and the absorbent material through thermal adhesion or ultrasonic adhesion. Furthermore, the surface of the nonwoven top sheet of the present invention is patterned or dimpled during embossing / laminating, thereby reducing the area contactingthe skin of a user. As described above, the nonwoven top sheet for a sanitary pad and diaper has a reduced amount of surface active agent contacting the skin of the user, has less lint on the surfacethereof, and has a reduced area contacting the skin of the user, thereby having improved skin friendliness.

Description

technical field [0001] The invention relates to an inner lining of a disposable diaper and a sanitary napkin. Disposable diapers or sanitary napkins consist of an inner liner surrounding an absorbent core and a cover. The inner liner of the disposable diaper and sanitary napkin of the present invention is a material of the surface directly in contact with the skin of the wearer. Background technique [0002] The preferred and important qualities for the inner liner of disposable diapers and sanitary napkins are no skin irritation, good touch, no lint, fast moisture transfer to the absorbent core, and good dryness. As the inner liners of existing disposable diapers and sanitary napkins, the quality mainly considers rapid absorbency and skin contact feeling, so hydrophilic non-woven fabrics are used in the parts that come into contact with the skin. Alternatively, use a perforated plastic film that has no wet properties on the surface. Hydrophilic non-woven fabrics used as ...
