Problems solved by technology

The patent uses EVOLON as the top layer of breast pads. Since EVOLON is a two-component spunbond spunlace nonwoven fabric, the weight per square meter is relatively high (generally the lowest is 40 grams), which will cause the top layer of breast pads to contain more water, which is not easy Comfortable and easy to breed bacteria. On the other hand, the cost of EVOLON spunbond spunlace nonwovens is also high, which increases the price of the final product
[0006] To sum up, although the material and structure of the surface non-woven fabric have been changed in the existing information about the non-shedding breast pads, there are disadvantages such as poor comfort, unsafe use, high moisture content and high material cost. Therefore, it is necessary to develop a breast pad that is not easy to shed and is safe and convenient to use

Abstract

The invention discloses an ultra-thin breast pad and a preparation method thereof and relates to the field of female lactation products. The ultra-thin breast pad is composed of a surface layer hydrophilic non-woven fabric, an intermediate absorbing layer and an impermeable bottom film. The surface layer hydrophilic non-woven fabric is a soft type double-component filament non-woven fabric composed of core layer PP / skin layer PE; and the intermediate absorbing layer is a hot melting non-woven fabric formed by blending core layer PP / skin layer PE and superabsorbent fibers. According to the method for preparing the ultra-thin breast pad, the surface layer hydrophilic non-woven fabric for preparing the ultra-thin breast pad is selected through a PE / PP double-component filament non-woven fabric soft bulkiness processing method, the superabsorbent fibers and the PE / PP double-component fibers are blended, the intermediate absorbing layer is prepared through a plain net hot air reinforcing method, so that the prepared ultra-thin breast pad has the advantages of being not subjected to fiber slip, being ultra-thin and breathable, having moisture breathability and being safe and healthy, and the problems that a breast pad not subjected to fiber slip is poor in comfort, unsafe, high in moisture content and high in material cost are solved.

Description

technical field [0001] The invention relates to the field of female breastfeeding products, in particular to an ultra-thin breast pad and a preparation method thereof. Background technique [0002] Breast pads are essential for breastfeeding mothers to absorb excess breast milk. They can absorb excess breast milk and secure the breast milk inside the absorbent layer of the breast pad to avoid wetting clothes. In addition, breast pads can also protect breastfeeding. Safe and healthy nipples for expectant mothers. Breast pads are divided into washable and disposable types according to the method of use. Washable breast pads can be used multiple times and are economical, but they are more troublesome to clean, and also have potential safety hazards caused by inability to sterilize; Pads are becoming more and more popular due to the fact that the adhesive on the back is fixed in place, which is clean and hygienic without cleaning. Usually, disposable breast pads are composed o...
