Abstract

manufacture of sanitary napkins, which consist of an absorbent medium and a protective covering; which at least One surface of the suction internal medium must be covered. Lining and skin contact parts of sanitary napkin users What has been improved Including cloth covering which has a structure of 2 layers together. The outer layer is the outer surface which will come into contact with user's skin and the inner layer which is on the inside of the outer layer This cover layer consists of 30 to 80% by weight of hot fusible fibers. The fibers are fusible at a temperature range of 90 to 140 degrees centigrade. and there is also a line hydrophobic fiber Hydrophobicfibre is composed of 70 to 20% by weight. This hydrophobic fiber does not melt at temperature below 140 degrees centigrade Such layers of cloth cover have between 0.5 and 1.2 mm thick under 1 g/cm2 pressure and 0.0 to 0.6 mm thick under 1 g/cm2 pressure. and a thickness between 0.2 and 0.6 millimeters at a pressure of 5 grams per square centimeter. Weight ratio between hot melted fibers / hydrophobic outer fibers There is a ratio range of 50/50 to 100/0 and the weight ratio between the fibers that are melted when hot/hydrophobic fibers at the inner layer There is a ratio between 20/80 and 60/40.

Claims (6)

1. In the manufacture of sanitary napkins, which consist of a absorbent medium and a covering layer. At least that Maximum must cover one side of the acting internal medium. Absorbent and the parts that touch the skin of the user sanitary napkin, what has been improved Ie cover cloth with a 2-layer structure coexisting The outer layer is the outer skin which is exposed. To the user's skin And the inner layer which is on the inside of the outer layer This mantle consists of 30 to 80% fusible fibers by weight, fusible at a temperature range of 90 to 140 degrees centigrade. And there are also lines Hydrophobic fiber (hydrophobicfibre) comprises 70 to 20% by weight. This hydrophobic fibers do not melt at The temperature is below 140 degrees centigrade. Such cover layer has Thickness between 0.5 and 1.2 mm under 1 gram per square centimeter of pressure and between 0.0 to 0.6 mm under pressure 1 gram per square centimeter. And thickness between 0.2 and 0.6 mm at under pressure of 5 g / cm2. Weight ratio between hot melt fibers / outer hydrophobic fibers It has a proportional range between 50/50 and 100/0 and the ratio of weight between the fibers fused when Hot / hydrophobic fibers on the inner layer Has helped proportions between 20/80 and 60/40. 2. Sanitary napkins according to claim 1, where the outer layer has a base weight between 5 and 15 grams per square meter. And the inner layer has a basic weight between 8 and 25 grams per square meter. 3. Sanitary napkins according to claim 1, which fibers are fused on It is heat treated with a resolution of 1.5 to 3 dinars and a hydrophobic filament with a resolution of 1.5 to 6 dinars. 4. Sanitary napkins according to claim 1, in which the hot fused fibers are polyethylene / polypropylene blends, and the hydrophobic fibers are Polypropylene or polyester fiber 5. Sanitary napkins according to claim 1, which the outer layer consists of 1.5 to 3 denier polyethylene / polypropylene blended fibers and 7 to 9 grams per square meter of base weight.
