[Solution] The soft moisture-proof and dehumidifying mat comprises, from top to bottom, a first needle-punched nonwoven fabric layer 1, a first hot-melt fiber mesh layer 2, a moisture-absorbing layer containing moisture-proof beads 3, a second hot-melt fiber mesh layer 4, and a second needle-punched nonwoven fabric layer 5, connected in order by a hot-melt composite material. The first and second needle-punched nonwoven fabric layers serve as the surface layers of the dehumidifying mat and offer high structural strength and tear resistance. At the same time, they are slightly napped, giving the dehumidifying mat a soft feel and improving comfort during use. Furthermore, the large interstices between the fibers allow the moisture-absorbing layer to better absorb moisture. The first and second hot-melt fiber mesh layers bond the first and second needle-punched nonwoven fabric layers together during the hot-melt composite process and serve to secure the moisture-proof beads.

Description

[Technical Field]

[0001] The present invention relates to the technical field of textile products, and in particular to a soft moisture-proof and moisture-dehumidifying mat. [Background technology]

[0002] In the summer, it is hot and rainy outside, and the indoor air is humid. Although air conditioners and dehumidifiers can be used to dehumidify, the humid environment in the gaps between the mat and the floor and carpet after long-term use can easily cause mold to grow and deteriorate. Currently, the dehumidifying problem of household textile products is mainly solved by laying dehumidifying mats.

[0003] Hot melt adhesive is a type of adhesive, mainly in the form of particles or powder, which melts into a liquid state after heating and is used to bond structural layers located on the upper and lower sides after cooling to form a strong adhesive effect.

[0004] However, most of the existing dehumidifying mats are made by mixing a hot melt adhesive and a moisture-proof bead powder mixture and then heating the mixture to form a dehumidifying layer with adhesive effect.

[0005] The applicant has found that the prior art has at least the following technical problems.

[0006] Hot melt adhesives form a hard layer after curing, which encases the moisture-proof bead mixture powder located inside, forming a relatively closed space. As a result, the exposed area of ​​the moisture-proof bead mixture powder is reduced, affecting moisture absorption efficiency. Furthermore, the presence of the hard layer makes the dehumidifying mat feel hard to the touch, making it uncomfortable to use. Furthermore, because hot melt adhesives have limited heat and water resistance, high temperatures and frequent washing can easily cause the hot melt adhesive to age, resulting in a decrease in adhesive strength, causing delamination of the dehumidifying mat and shortening its service life.

[0007] Even if the EVA hot melt adhesive and moisture-proof bead powder mixture are uniformly mixed before heating, the uncontrollable flow characteristics of the hot melt adhesive during the heating process can easily cause the moisture-proof bead powder mixture to be unevenly distributed, which will adversely affect the moisture absorption effect of the dehumidifying mat and reduce its overall performance.

[0008] For example, application number CN201710149542.9 discloses a dehumidifying, dust mite-killing, and deodorizing nonwoven fabric mat.

[0009] In view of this, the present invention is proposed. Summary of the Invention

[0010] The purpose of this invention is to provide a soft moisture-proof and moisture-wicking mat that solves the design defects of prior art moisture-proof mats, such as forming an adhesive moisture-wicking layer by mixing a hot melt adhesive with a moisture-absorbing bead powder and then heating the mixture, and then forming a hard layer after the hot melt adhesive hardens, which encapsulates the moisture-proof bead powder inside, adversely affecting moisture absorption efficiency, and at the same time making the mat feel hard and uncomfortable to use. The various technical effects produced by the preferred technical means of the present invention are described in detail below.

[0011] To achieve the above objectives, the present invention provides the following technical means:

[0012] The soft moisture-proof and moisture-dehumidifying mat provided by the present invention comprises, from top to bottom, a first needle-punched nonwoven fabric layer, a first hot-melt fiber mesh layer, a moisture-absorbing layer, a second hot-melt fiber mesh layer, and a second needle-punched nonwoven fabric layer, which are connected in order by a hot-melt composite material.

[0013] Preferably, the gram weight of the first needle-punched nonwoven fabric layer and the second needle-punched nonwoven fabric layer is 40 g / m 2 ~250g / m 2 is.

[0014] Preferably, the gram weight of the hot melt fiber mesh of the first hot melt fiber mesh layer and the second hot melt fiber mesh layer is 5 g / m 2 ~30g / m 2 is.

[0015] Preferably, the amount of moisture-proof beads used in the moisture-absorbing layer is 20 g / m 2 ~180g / m 2 is.

[0016] Preferably, a first positioning groove is provided on the underside of the first hot-melt fiber mesh layer, and a second positioning groove is provided on the upper surface of the second hot-melt fiber mesh layer, and the first positioning groove and the second positioning groove are arranged in a matrix, with one-to-one correspondence between them, and are used to accommodate the moisture-proof beads.

[0017] Preferably, the first needle-punched nonwoven fabric layer and the second needle-punched nonwoven fabric layer contain any two or more of polyester fibers, viscose fibers, nylon fibers, cotton fibers, and flax fibers.

[0018] Preferably, a functional agent is contained within the fibers of the first needle-punched nonwoven fabric layer and the second needle-punched nonwoven fabric layer.

[0019] Preferably, the functional agent includes any one or any combination of an antibacterial deodorant, a deodorizer, an antifouling agent, an anti-mite agent, or an anti-fungal agent.

[0020] Preferably, the particle diameter of the moisture-proof beads is 0.3 mm to 5 mm.

[0021] Preferably, the shape of the moisture barrier beads comprises a regular or irregular geometric shape.

[0022] The preferred technical means of the present invention at least achieve the following technical effects:

[0023] This invention avoids the design defects of prior art dehumidifying mats, such as a first needle-punched nonwoven fabric layer, a first hot-melt fiber mesh layer, a moisture-wicking layer, a second hot-melt fiber mesh layer, and a second needle-punched nonwoven fabric layer, connected in order from top to bottom by a hot-melt composite material. The first and second needle-punched nonwoven layers function as the surface layers of the dehumidifying mat. They have high structural strength, good tear resistance, and a long service life. They also have no fuzz, giving the dehumidifying mat a soft feel and thickness, improving comfort during use. They are easy to store and wrinkle-free when folded and unfolded. Furthermore, the large interstices between the fibers create air passages, allowing the moisture-wicking layer to better absorb moisture from the external environment. The first and second hot-melt fiber mesh layers are located on both the top and bottom of the moisture-wicking layer and serve to bond the first and second needle-punched nonwoven layers together during the hot-melt compounding process, thereby securing the moisture-proof beads. The first and second hotmelt fiber mesh layers are melted and then coagulate at their fiber intersections. This prevents the formation of a dense, hard layer upon hardening, preventing excessive envelopment of the moisture-absorbing layer, allowing the moisture-absorbing layer to properly perform its dehumidifying function. The moisture-proof beads in the moisture-absorbing layer are used to absorb moisture from the environment. The first and second hotmelt fiber mesh layers protect and support the moisture-proof beads on their upper and lower sides, respectively, without adversely affecting the aesthetics of the dehumidifying mat. This prevents the beads from being enveloped by the dense, hard layer, increasing their exposed area, allowing them to effectively absorb moisture and achieve the dehumidifying function of the dehumidifying mat.

DETAILED DESCRIPTION OF THE INVENTION

[0025] In order to make the purpose, technical means and advantages of the present invention clearer, the technical means of the present invention will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without any creative work shall all fall within the protection scope of the present invention.

[0026] Example 1: As shown in FIG. 1, the present invention provides a soft moisture-proof and moisture-dehumidifying mat, which includes, from top to bottom, a first needle-punched nonwoven fabric layer 1, a first hot-melt fiber mesh layer 2, a moisture-absorbing layer, a second hot-melt fiber mesh layer 4, and a second needle-punched nonwoven fabric layer 5, which are connected in this order by a hot-melt composite material.

[0027] Furthermore, the first needle-punched nonwoven fabric layer 1 and the second needle-punched nonwoven fabric layer 5 are both made of needle-punched nonwoven fabric.

[0028] The first and second hot-melt fiber mesh layers 2 and 4 are made of hot-melt fiber mesh. After the hot-melt fiber mesh is hot-melted, the fibers aggregate at their intersections, reducing the porosity of the mesh but maintaining a certain degree of breathability.

[0029] The moisture-wicking layer includes moisture-proof beads 3 uniformly disposed between a first hot-melt fiber mesh layer 2 and a second hot-melt fiber mesh layer 4 .

[0030] The first needle-punched nonwoven fabric layer 1 and the second needle-punched nonwoven fabric layer 5 function as the surface layers of the dehumidifying mat because the needle-punched nonwoven fabric has high structural strength, good tear resistance, and a long service life. At the same time, compared to ordinary nonwoven fabrics, the nonwoven fabric has a higher nap and is thicker, giving the dehumidifying mat a softer feel overall, improving comfort during use. It also folds and stores for easy storage without wrinkles, allowing for easy unfolding. Furthermore, the large interstices between the fibers of the needle-punched nonwoven fabric create air passages, allowing the moisture-absorbing layer to better absorb moisture in the surrounding environment. Furthermore, the needle-punched nonwoven fabric has a porous structure, which allows it to absorb moisture to a certain extent, further improving the dehumidifying effect of the dehumidifying mat.

[0031] The first and second hot-melt fiber mesh layers 2 and 4 are positioned above and below the moisture-absorbing layer, and serve to bond the first and second needle-punched nonwoven layers 1 and 5 together during the hot-melt compounding process, and to secure the moisture-proof beads 3. Unlike hot-melt adhesives, the hot-melt fiber mesh aggregates at the fiber intersections after hot-melting, maintaining its mesh structure without forming a dense, hard layer like hot-melt adhesives after curing. This further improves the softness of the dehumidifying mat and ensures a strong connection between the first and second needle-punched nonwoven layers 1 and 5, while also securing the moisture-proof beads 3. This prevents excessive wrapping of the moisture-proof beads 3, allowing them to properly perform their dehumidifying function. Furthermore, compared to hot melt adhesives, the present invention uses the first hot melt fiber mesh layer 2 and the second hot melt fiber mesh layer 4 for bonding, which makes the dehumidifying mat easier to wash afterwards, and eliminates the problems of reduced cleaning effectiveness or damage to the dehumidifying mat caused by hot melt adhesives.

[0032] The moisture-proof beads 3 in the moisture-absorbing layer are used to absorb moisture in the external environment. The upper and lower sides of the moisture-proof beads 3 are protected and supported by the first hot-melt fiber mesh layer 2 and the second hot-melt fiber mesh layer 4, respectively, which does not adversely affect the aesthetic appearance of the dehumidifying mat and avoids being enveloped by a dense, hard layer. This increases the exposed area of ​​the moisture-proof beads 3, allowing them to effectively absorb moisture and achieve the moisture-proof function of the dehumidifying mat.

[0033] In an optional embodiment, the needle-punched nonwoven fabric of the first needle-punched nonwoven fabric layer 1 and the second needle-punched nonwoven fabric layer 5 includes any two or more of polyester fibers, viscose fibers, nylon fibers, cotton fibers, and flax fibers.

[0034] Polyester fiber has good structural strength, elasticity, wrinkle resistance and shape retention, so the needle-punched nonwoven fabric is less likely to deform during use and has a long service life.

[0035] Viscose fiber has good moisture absorption, softness, breathability and spinnability, so the needle-punched nonwoven fabric has a soft feel, is easy to dye and does not generate static electricity.

[0036] Nylon fibers have good abrasion resistance, breaking strength, breaking elongation, moisture absorption and recovery properties, so the needle-punched nonwoven fabric is less likely to break even after long-term use.

[0037] Cotton fibers have good structural strength and are highly moisture-absorbent and breathable, so needle-punched nonwoven fabrics have good moisture-absorbent and breathable properties.

[0038] Flax fiber has good moisture absorption, breathability, antibacterial and antistatic properties, so the needle-punched nonwoven fabric has natural antibacterial and deodorizing functions.

[0039] Since different fibers each have their own unique properties, they can be flexibly combined as needed, adapting to different usage scenarios and offering a wide range of uses.

[0040] In an optional embodiment, a functional agent is included within the fibers of first needle-punched nonwoven layer 1 and second needle-punched nonwoven layer 5 .

[0041] In an alternative embodiment, the functional agent comprises any one or any combination of prior art antibacterial deodorants, deodorizers, stain repellents, anti-mite agents or anti-fungal agents.

[0042] In this way, the first needle-punched nonwoven fabric layer 1 and the second needle-punched nonwoven fabric layer 5 have antibacterial and deodorizing properties, deodorizing properties, stain resistance, anti-mite properties, anti-fungal properties, and the like.

[0043] Functional agents can be flexibly combined as needed, making the dehumidifying mat suitable for a wide range of uses.

[0044] In an alternative embodiment, the gram weight of the first needle-punched nonwoven fabric layer 1 and the second needle-punched nonwoven fabric layer 5 is 40 g / m2 ~250g / m 2 is.

[0045] In this way, the gram weight of the needle-punched nonwoven fabric can be selected appropriately depending on the situation of use, thereby achieving a balance between cost and performance of the first needle-punched nonwoven fabric layer 1 and the second needle-punched nonwoven fabric layer 5.

[0046] In an alternative embodiment, the gram weight of the hot melt fiber mesh of the first hot melt fiber mesh layer 2 and the second hot melt fiber mesh layer 4 is 5 g / m 2 ~30g / m 2 is.

[0047] In this way, the gram weight of the hot melt fiber mesh can be selected appropriately depending on the situation of use, thereby achieving a balance between cost and performance of the first hot melt fiber mesh layer 2 and the second hot melt fiber mesh layer 4.

[0048] In an alternative embodiment, the amount of moisture-proof beads 3 used in the moisture-absorbing layer is 20 g / m 2 ~180g / m 2 is.

[0049] In this way, the amount of moisture-proof beads 3 used can be selected appropriately depending on the application situation, so that different humidity environments and application requirements can be met.

[0050] In an alternative embodiment, the particle diameter of the moisture-proof beads 3 is 0.3 mm to 5 mm.

[0051] In this way, moisture-proof beads 3 with an appropriate particle size can be selected according to the specifications of the moisture-proof mat, and different humidity environments and usage requirements can be met.

[0052] As an alternative embodiment, the shape of the moisture-proof beads 3 includes regular or irregular geometric shapes.

[0053] The moisture-proof beads 3 having a regular shape can be more uniformly distributed between the first hotmelt fiber mesh layer 2 and the second hotmelt fiber mesh layer 4, which allows for mass production, high production efficiency, and good consistency.

[0054] The irregularly shaped moisture-proof beads 3 have a larger contact area with the air than the regularly shaped moisture-proof beads 3, and can more effectively absorb moisture in the external environment.

[0055] Furthermore, as shown in FIG. 1, the moisture-proof beads 3 are hemispherical, and their flat surfaces can adhere well to the hot-melt fiber mesh of the second hot-melt fiber mesh layer 4, thereby reducing the displacement of the moisture-proof beads 3 during the hot-melt process and improving the adhesion between the moisture-proof beads 3 and the hot-melt fiber mesh layer.

[0056] Example 2: Example 2 differs from Example 1 in the following respects: as shown in Figures 2 to 4, a first positioning groove 202 is provided on the lower surface 201 of the first hot-melt fiber mesh layer 2, and a second positioning groove 402 is provided on the upper surface 401 of the second hot-melt fiber mesh layer 4, the first positioning groove 202 and the second positioning groove 402 are arranged in a matrix, with one pair provided, and are used to store moisture-proof beads 3.

[0057] A mold with a matrix-shaped protrusion structure is used to press the hot melt fiber mesh of the first hot melt fiber mesh layer 2 and the second hot melt fiber mesh layer 4 to form the first positioning groove 202 and the second positioning groove 402.

[0058] As shown in FIGS. 2 to 4, the moisture-proof beads 3 are spherical, and the first positioning grooves 202 and the second positioning grooves 402 are hemispherical to fit the moisture-proof beads 3.

[0059] When the first hotmelt fiber mesh layer 2 is laid on the second hotmelt fiber mesh layer 4, the first positioning grooves 202 and the second positioning grooves 402 correspond one-to-one to each other, and together form positioning spaces for the moisture-proof beads 3. The positioning spaces arranged in a matrix can accommodate and position the moisture-proof beads 3, thereby ensuring that the moisture-proof beads 3 are securely and uniformly positioned between the first hotmelt fiber mesh layer 2 and the second hotmelt fiber mesh layer 4 before hotmelt application, and preventing unintended movement of the moisture-proof beads 3.

[0060] Then, during the hot-melt process, the moisture-proof beads 3 are already restricted by the first positioning grooves 202 and the second positioning grooves 402 before they are hot-melted. Therefore, even after the hot-melt fiber mesh is hot-melted, it can aggregate at the intersections of the hot-melt fibers along the surface of the moisture-proof beads 3, thereby reducing the movement of the moisture-proof beads 3 and improving the connection strength between the moisture-proof beads 3 and the hot-melt fiber mesh.

[0061] Since the position of the moisture-proof beads 3 is fixed, the moisture-absorbing layer can maintain a stable moisture-absorbing function during long-term use.
