Abstract
Description
Technical Field
[0001] The utility model belongs to the field of composite sponges, and particularly relates to a flame composite sponge and a mattress with formaldehyde removal function. Background Art
[0002] Existing non-woven fabric packages with formaldehyde removal and purification functions mostly use formaldehyde removal catalysts, which are fixed between non-woven fabrics and TC fabrics through a hot pressing composite process and applied to the quilting layer of mattresses in the form of composite fabrics. At present, the application of granular powdered formaldehyde removal catalysts in mattresses mainly has the following problems:
[0003] 1) The formaldehyde removal catalyst is distributed in a free state, and there is a risk of catalyst shedding during the cutting process after compounding;
[0004] 2) The formaldehyde removal catalyst is tightly compounded by the non-woven fabric and the TC fabric, and the probability of the catalyst contacting with the formaldehyde molecules is relatively small, which reduces the formaldehyde removal efficiency of the catalyst;
[0005] 3) The overall comfort of the composite fabric of non-woven fabric and TC fabric is deviated, which affects the overall sleeping feeling of the mattress. Utility Model Content
[0006] In view of the problem that the unreasonable setting of existing formaldehyde-removing fabrics leads to unsatisfactory formaldehyde removal effect, the utility model provides a flame composite sponge and mattress with formaldehyde removal function, which ensures the comfort and breathability of use through the sponge body layer, and a formaldehyde-removing functional layer is sandwiched between two adjacent sponge body layers to effectively prevent the formaldehyde-removing functional layer from falling off.
[0007] The utility model adopts the following technical scheme: a flame composite sponge with formaldehyde removal function, comprising at least two stacked sponge body layers, with a formaldehyde removal functional layer sandwiched between two adjacent sponge body layers.
[0008] In the present application, the sponge body layer has a porous structure and has good air permeability. It not only has good comfort, but also can ensure that the formaldehyde removal functional layer is in contact with the air, thereby ensuring the formaldehyde removal effect. The formaldehyde removal functional layer is arranged between two adjacent sponge body layers. The laminated structure can provide better protection for the formaldehyde removal functional layer and effectively prevent the formaldehyde removal functional layer from being bumped or falling off.
[0009] Furthermore, the formaldehyde-removing functional layer is provided with formaldehyde-removing particles, and the formaldehyde-removing particles are formaldehyde-removing catalysts or activated carbon. The formaldehyde-removing function is achieved by the formaldehyde-removing particles.
[0010] Furthermore, the formaldehyde-removing particles are sandwiched on the surface of the sponge body layer located below, and the flame composite connection layer is arranged on the lower surface of the sponge body layer located above. The flame composite connection layer is connected from the upper part of the formaldehyde-removing particles to the sponge body layer located below, so that an enclosed area is formed around the formaldehyde-removing particles between adjacent sponge body layers, and the enclosed area and the formaldehyde-removing particles form the formaldehyde-removing functional layer. The sponge body layers all have a hole structure, and the formaldehyde-removing particles can be sandwiched in the holes. The flame composite layer is arranged on the lower surface of the sponge body layer located above, and the flame composite layer forms a reliable connection between the surface of the formaldehyde-removing particles and the sponge body layer located below, so that the adjacent sponge bodies form an enclosed area around the formaldehyde-removing particles, and the formaldehyde-removing particles are surrounded by the sponge body layer, which effectively solves the risk of falling off. The formaldehyde-removing particles will not be covered by the flame composite layer, and the formaldehyde-removing effect is guaranteed.
[0011] Furthermore, the formaldehyde-removing functional layer includes a sponge interlayer, in which the formaldehyde-removing particles are sandwiched, and the sponge interlayer is respectively connected to the sponge body layer located above and below through a flame composite connecting layer.
[0012] Furthermore, the particle size of the formaldehyde-removing particles is 50-80 meshes. If the particle size of the formaldehyde-removing particles is too large, the specific surface area is small, the adsorption performance will be affected, and the formaldehyde-removing effect will be compromised; if the formaldehyde-removing particles are too small, they will fall into the gaps in the sponge body, the formaldehyde-removing particles cannot contact the formaldehyde molecules in the air well, and the formaldehyde-removing effect is not ideal.
[0013] Furthermore, the thickness of the sponge body layer is 0.5-3 cm. A sponge body layer of appropriate thickness can ensure comfort in use.
[0014] Furthermore, the flame composite connection layer is formed on the surface of the sponge body by flame and pressure roller. The sponge flame composite process refers to the sponge being burned quickly by a linear gas burner to melt its surface to produce an adhesive, and the sponge producing the adhesive is bonded to other sponges or fabrics under the pressure of the pressure roller, thereby forming two or more layers of composite materials. The connection is relatively firm and reliable.
[0015] A mattress comprises an upper layer, a comfort layer, a supporting core layer and a lower layer. A peripheral edge is arranged on the outer side of the supporting core layer. The upper layer, the comfort layer, the lower layer or the peripheral edge adopts the flame composite sponge with formaldehyde removal function.
[0016] Furthermore, an upper fabric layer is provided on the upper surface of the sponge body layer at the top, and a flame composite connection layer is provided between the sponge body layer at the top and the upper fabric layer. The upper fabric layer can protect the sponge body and effectively reduce the damage to the sponge body caused by scratches by external forces, and the flame composite connection layer makes the connection between the upper fabric layer and the flame composite connection layer firm and reliable. A non-woven fabric layer is provided on the lower surface of the sponge body layer at the bottom, and a flame composite connection layer is provided between the sponge body layer at the bottom and the non-woven fabric layer. The non-woven fabric layer can protect the sponge body layer at the bottom to prevent the sponge body from being scratched or scratched by external forces during use, thereby generating debris and residues, which affects the experience.
[0017] The beneficial effects of the utility model are as follows: the present application is a flame composite sponge and mattress with formaldehyde removal function. The sponge body layer has a hole structure and has good air permeability. It not only has good comfort, but also can ensure that the formaldehyde removal functional layer is in contact with the air, thereby ensuring the formaldehyde removal effect. The formaldehyde removal functional layer is arranged between two adjacent sponge body layers. The laminated structure can provide better protection for the formaldehyde removal functional layer, and effectively prevent the formaldehyde removal functional layer from being bumped or falling off.
