Problems solved by technology

[0010] It can be concluded from the above-mentioned patent documents that the developed composite absorbent cores all use polymers as the main absorbent components, which are prone to powder falling or not added in the production process, and are prone to leakage or lumps during use. , ultimately leading to an effect on the absorption of the product
[0011] In addition, the processing process of the existing nursing pads is relatively long. First, the non-woven fabric processing factory first produces the surface non-woven fabric and the bottom film, and then the sanitary material factory combines the non-woven fabric, the bottom film and wood pulp polymers to form Formation, that is to say, the finished product of a nursing pad can only be completed through the raw material factory and the sanitary product assembly factory. The lengthy production process wastes a lot of manpower, material and financial resources. Therefore, it is very difficult to develop and produce new nursing pads with new materials and new methods.

Embodiment 1

[0037] 1) Preparation of the surface layer: open the polylactic acid fiber with a linear density of 1.2D and a length of 38mm, and directly feed it into the first carding machine through the air-flow cotton box, and directly form a web after passing through the doffer and stripping roller to form the upper layer The surface layer in the combination, the grammage is 10g / m 2 .

[0038] 2) Preparation of the diversion moisture-absorbing layer: the water-repellent HDPE / PP bicomponent fiber with a linear density of 6D and a length of 76mm and the superabsorbent fiber with a linear density of 10D and a length of 76mm were developed according to a ratio of 95:5. After being loosely mixed, it is fed into the second carding machine through the air-flow cotton box, and is directly formed into a web after passing through the doffer and the stripping roller to form a diversion and moisture-absorbing layer in the upper layer combination, with a grammage of 20g / m 2 .

Abstract

The invention discloses a portable nursing pad containing a polylactic acid fiber and a preparation method thereof. A conventional nursing pad has a relatively long processing flow, and the long production process wastes a lot of manpower, material resources and financial resources. The nursing pad is composed of an upper-layer assembly body and an impermeable bottom layer, wherein the upper-layer assembly body is composed of a surface layer composed of a polylactic acid fiber net, a flow-guiding moisture-absorption layer composed of a water-repellency bicomponent fiber and a superabsorbent fiber net, and an absorption layer composed of a hydrophilic bicomponent fiber and a superabsorbent fiber net, and the three layers are subjected to hot melt compounding to form a whole; the upper layer and the impermeable bottom layer are subjected to hot melt adhesive compounding to form a whole. The prepared nursing pad has the characteristics of short process flow, good molding, bacteriostasis, deodorness, gas permeation and dryness, does not produce lumps and allows powder not to fall off in a use process, and is an ideal material for preparing disposable medical treatment health supplies.

Description

technical field [0001] The invention relates to a sanitary nursing pad used in daily life, in particular to a portable nursing pad containing polylactic acid fiber and a preparation method thereof. Background technique [0002] Nursing pad is a kind of disposable sanitary product with large capacity of absorption and water retention, no leakage, soft and comfortable, widely used in child care, incontinence of paralyzed patients, maternity care, women's menstrual period, etc. The conventional nursing pad structure is mainly composed of three layers, and the sequence from the top layer to the bottom layer is: surface layer, middle absorbent core layer and back layer. The material used for the surface layer is usually two-component synthetic fiber air-through non-woven fabric, polypropylene hot-rolled cloth or spunbond non-woven fabric; the middle absorbent core layer is composed of fluff pulp and superabsorbent resin; the back layer is mainly PP breathable film. It can be see...
