Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to overcome the unstable hygroscopic effect and poor hygroscopic capacity caused by the excessively long fiber average length in the hygroscopic layer of hygroscopic products in the prior art, the use of hemp material leads to high cost and poor comfort, and the fiber The disadvantage of poor cohesion ability between fibers in too short a time is not easy to form into tablets. Provide a hygroscopic layer in sanitary hygroscopic products with stable hygroscopic effect, high hygroscopic capacity, low cost, good comfort, and easy to form into tablets.

Embodiment 1

[0020] Such as figure 1 As shown, the longitudinal sectional view of the hygroscopic layer in the present invention, the hygroscopic layer includes a mixed hygroscopic sheet 11 with a thickness of about 1-5 mm, which contains crushed jute fibers and crushed wood pulp paper, and is sandwiched between the upper and lower layers. The wood pulp paper hygroscopic sheet 12 containing only crushed wood pulp paper with a thickness of about 1-5 mm between the mixed hygroscopic sheets 11 is sandwiched between the two intervals formed by the mixed hygroscopic sheet 11 and the wood pulp paper hygroscopic sheet 12 Super absorbent resin (SAP) layer2. In order to prevent loss of the superabsorbent resin due to leakage, the upper and lower layers of the mixed hygroscopic sheet 11 and the edge of the wood pulp paper hygroscopic sheet 12 can be pressed together so that the superabsorbent resin layer 2 is fixed in the gap. The average length of the jute fibers in the hybrid hygroscopic sheet 11...

Embodiment 2

[0026] The average length of the hemp fiber and the content of the hemp fiber in the moisture-absorbing sheet 1 in Example 1 were changed. In this embodiment, the average length of the hemp fiber in the hygroscopic sheet 1 is 1mm, and the hemp fiber content is 30%. Because the average length of the hemp fiber is shorter than 5 mm, the fibers are easier to mix evenly and improve the moisture absorption stability; because the fibers with a shorter average length have poor cohesion ability, the content of the hemp fiber in the wet sheet is correspondingly reduced, but to a certain extent weaken the antibacterial ability and air permeability of the hygroscopic layer, but the hemp fiber content still has good hygroscopic stability, air permeability, and antibacterial and antibacterial ability when the content of hemp fiber is 30wt%.

Embodiment 3

[0028] The average length of the hemp fiber and the content of the hemp fiber in the moisture-absorbing sheet 1 in Example 1 were changed. In this embodiment, the average length of the hemp fiber in the hygroscopic sheet 1 is 0.5 mm, and the content of the hemp fiber is 10 wt%. At this time, because the average length of the hemp fiber is shorter, it is easier to mix evenly, and the moisture absorption stability is higher, but at the same time, it is necessary to increase the content of raw pulp paper in the moisture-absorbing sheet. Compared with hemp fiber content of 30wt% and 50wt%, the capacity is lower.

Abstract

The invention relates to a moisture adsorption fibrilia layer comprising at least two layers of moisture adsorption pieces that are overlapped. The moisture adsorption piece comprises a mixed moisture adsorption piece containing smashed fibrilia and smashed raw stock paper and a moisture adsorption piece of raw stock paper only containing the smashed raw stock paper, wherein, the weight percentage content of the fibrilia in the mixed moisture adsorption piece is 10 to 90wt percent. The moisture adsorption layer of the invention has the advantages of stable moisture adsorption effect, strong moisture adsorption ability, lower cost, good comfortability and easy sheet-forming.

Description

technical field [0001] The invention relates to the field of sanitary hygroscopic articles for external use, in particular to a hygroscopic layer in sanitary hygroscopic articles for external use. Background technique [0002] Since hygienic absorbent products such as sanitary napkins, panty liners, and breast pads need to be in contact with the human body for a long time, there are high requirements for their air permeability. Hygienic hygroscopic products in the prior art are usually made of cotton materials or chemical synthetic materials in order to meet the requirements of certain liquid absorption capacity and softness, but the air permeability of these materials is not ideal, and when used for a long time, Especially when used in hot weather, it will produce a hot and humid feeling, and may cause skin itching, redness, and even herpes and other diseases. [0003] In order to improve the breathability and antibacterial ability of hygienic hygroscopic products as a who...
