CN-224224696-U - Soft dampproofing dehumidification pad

Abstract

The utility model provides a soft dampproof dehumidifying pad which comprises a first needled non-woven fabric layer, a first hot-melt fiber net layer, a moisture absorption layer, a second hot-melt fiber net layer and a second needled non-woven fabric layer which are sequentially connected in a hot-melt composite mode from top to bottom. The first needled non-woven fabric layer and the second needled non-woven fabric layer are used as the surface layer of the dehumidifying pad, have higher structural strength and good tearing resistance, and meanwhile, are fluffy and soft, so that the dehumidifying pad has soft hand feeling, and the using comfort is improved. Moreover, the fiber gaps are larger, so that the moisture absorption layer can absorb moisture better. The first hot-melt fiber web layer and the second hot-melt fiber web layer play a role in bonding the first needled non-woven fabric layer and the second needled non-woven fabric layer and fixing the moisture-proof beads in the hot-melt compounding process, and after the hot-melt fiber web is heated and melted, the hot-melt fiber web is condensed on fiber crossing points of the hot-melt fiber web layer, a compact hard layer is not formed, so that the moisture-proof beads can normally absorb moisture in an external environment.

Description

Soft dampproofing dehumidification pad Technical Field The utility model relates to the technical field of textile products, in particular to a soft dampproof dehumidifying pad. Background The outside of the summer is stuffy and rainy, and the inside of the house is moist, and the air conditioner or the dehumidifier can be used for dehumidifying, but the gap between the floor and the carpet on the mattress or the gap between the floor and the carpet can be easily mildewed and changed due to the moist environment. At present, the dehumidification problem of home textile products is mainly solved by paving a dehumidification pad. The hot melt adhesive is an adhesive, is mostly in the form of particles or powder, is melted into a liquid state after being heated, is used for bonding structural layers on the upper side and the lower side of the adhesive, and forms a firm bonding effect after being cooled. However, most of the existing dehumidification pads are heated after being mixed by hot melt adhesive and moisture-proof bead mixed powder, so that a dehumidification layer with an adhesive effect is formed. The present inventors found that there are at least the following technical problems in the prior art: The hot melt adhesive is solidified to form a hard layer, and the hard layer can wrap the moisture-proof bead mixed powder in the hot melt adhesive to form a relatively closed space, so that the exposed area of the moisture-proof bead mixed powder is small, and the moisture absorption efficiency is affected. Moreover, the feeling of the dehumidifying pad is hardened due to the existence of the hard layer, and the comfort of use is poor. Furthermore, because the heat resistance and the water resistance of the hot melt adhesive are limited, the hot melt adhesive is easy to age and even lose viscosity under the condition of high temperature or frequent cleaning, and the delamination phenomenon of the dehumidification pad is further caused, so that the service life of the dehumidification pad is shortened. In addition, even the EVA hot melt adhesive adds dampproof bead mixed powder misce bene before heating, but in the heating process, because the flow characteristic of hot melt adhesive is uncontrollable, the inhomogeneous condition of dampproof bead mixed powder distribution appears easily, can further influence the moisture absorption effect of dehumidification pad, reduces its wholeness ability. For example, application number CN201710149542.9 discloses a nonwoven mattress for dehumidifying, removing mites and deodorizing. In view of this, the present invention has been made. Disclosure of utility model The utility model aims to provide a soft dampproof dehumidifying pad, which solves the technical problems that the design of the dehumidifying pad in the prior art has defects, a dehumidifying layer with an adhesive effect is formed by heating after hot melt adhesive and moisture-absorbing bead mixed powder are mixed, and the moisture-absorbing efficiency is affected by wrapping the moisture-absorbing bead mixed powder in the hot melt adhesive due to the fact that a hard layer is formed after the hot melt adhesive is solidified, and meanwhile, the feel of the dehumidifying pad is hardened and the using comfort is poor. The preferred technical solutions of the technical solutions provided by the present utility model can produce a plurality of technical effects described below. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a soft dampproof dehumidifying pad, which comprises a first needled non-woven fabric layer, a first hot-melt fiber net layer, a moisture absorption layer, a second hot-melt fiber net layer and a second needled non-woven fabric layer which are sequentially connected in a hot-melt composite manner from top to bottom.
