At present, most of furniture dustproof cushions in the market are polyester-cotton blended woven fabrics, and the dustproof is carried out by depending on the high density of the fabrics. However, such woven fabrics generally have no flame retardant and moisture proof effects, which can not effectively reduce the probability of fire hazard and can not ensure the drying condition of furniture articles.
Disclosure of Invention
Based on the defects in the prior art, the invention aims to provide the furniture dustproof cloth with the flame-retardant and moisture-proof effects, and the product can protect furniture and has good flame-retardant performance and moisture-proof performance; furthermore, through component selection, the product has better hand feel and launderability, and has a longer service life and a better use experience than existing products.
In order to achieve the purpose, the invention adopts the technical scheme that:
a furniture dustproof cloth with flame-retardant and damp-proof effects sequentially comprises an upper layer, a middle layer and a lower layer from outside to inside;
the upper layer and the lower layer are polyester spunbonded non-woven fabrics, flame retardant is introduced into the polyester spunbonded non-woven fabrics, and the flame retardant contains an organic silicon softener and trimethylol melamine resin (TMM);
the middle layer is a polyethylene film, and the density of the polyethylene film is 0.90-0.94g/cm3。
Preferably, the polyester spunbonded nonwoven incorporates a flame retardant by impregnation.
The furniture dustproof cloth with the flame-retardant and damp-proof effects adopts a sandwich structure, adopts the polyester spun-bonded non-woven cloth with dust prevention and flame retardance as the upper surface layer and the lower surface layer, and adopts the low-density polyethylene film as the middle layer, so that the effect of isolation and water resistance can be effectively achieved, and meanwhile, the layers are tightly connected, so that the service life is long; the flame retardant of the polyester spunbonded nonwoven fabric simultaneously contains the organic silicon softener and the TMM resin for compounding, the TMM resin releases inert gas when being heated to take away heat, and the organic silicon softener is melted on the surface of a base material to form a compact and stable silicon-containing carbon layer when being combusted, so that a good synergistic flame retardant effect is achieved, the furniture protection effect of a product can be further improved, the polyester spunbonded nonwoven fabric layer can be endowed with excellent washing resistance and comfortable hand feeling through synergistic interaction, the intrinsic texture is soft, and discomfort such as frizziness and the like can not occur after long-term use.
In addition, the inventor discovers that the impregnation method can ensure that the flame retardant in the polyester spunbonded nonwoven fabric is introduced in the highest content and has the best effect through different flame retardant introduction modes.

The tests of the inventor show that the fiber web surface density and the thickness of the polyester spunbonded nonwoven fabric and the thickness of the polyethylene film have influence on the forming effect of a final product, when the fiber web surface density is increased, the product has rough hand feeling and poor drapability, can not well cover large furniture, and has a small use range; when the surface density is reduced, the mechanical strength of the product is insufficient, and the washing resistance is weakened; when the thickness of the fiber web is increased, the volume area density of the product is reduced, the porosity is increased, the protection capability is weakened, the washing resistance is weakened, and the service life is shortened; the reduced thickness results in a reduced product drape, and reduced flame and moisture resistance. On the other hand, the polyethylene film having a large thickness causes a decrease in interlayer adhesion strength, a decrease in washing resistance, and a decrease in service life, and the polyethylene film having a small thickness causes a decrease in mechanical strength of the product, which also affects the service life.

Effect example 1
In order to verify the performance of the furniture dustproof cloth with flame-retardant and moisture-proof effects, the flame-retardant performance, the washing resistance and the moisture-proof performance of the products obtained in each embodiment and each proportion are tested and evaluated, and the test method comprises the following steps:
(1) testing is carried out according to the GB/T5455-2014-grade flame-retardant textile requirement testing method;
(2) cutting each product into 1m × 1m samples, putting into a Haier XQB90-BM1269 washing machine, washing with clear water for 30min, and observing the times of sample breakage;
(3) testing the moisture absorption rate of each product according to GB/T12704.1-2009;
(4) the softness of the product was tested according to GB/T39371-;
(5) the products were tested for drapability according to GB/T23329-;
the test results are shown in table 1.
TABLE 1
Figure BDA0003567860300000101
From the performance tests, the furniture dustproof cloth prepared by the embodiments of the invention has good flame retardance (the burning damage length is not more than 200mm), washing resistance (the washing resistance times are more than 200 times) and moisture-proof effect (the moisture absorption rate is less than 30g × m)- 2.d-1) The softness is high (the softness is more than 0.5mm), the optimal drapability can reach nearly 20 percent and can be adjusted according to actual requirements, and the product can completely replace various existing products sold in the market. From the performance of the comparative example 1, compared with the method for introducing the flame retardant into the polyester spunbonded nonwoven fabric by adopting the impregnation method, the product prepared by adopting other methods is difficult to achieve ideal flame retardant and washing resistant effects; from the product performance obtained in comparative example 2, the middle layer polyethylene film in the product of the invention is the key of the moisture resistance, and if the product without the middle layer does not have the ideal moisture resistance effect, the ideal moisture resistance effect is difficult to achieve; it is understood from comparative examples 3 and 4 that both the TMM resin and the silicone softener in the flame retardant have a synergistic effect, and lack of both results in insufficient product performance. From the examples 1, 4 to 5 and 10 to 11, it can be seen that the thickness of the middle layer polyethylene film has a certain influence on the performance of the product, and if the thickness is too thin or too thick, the service life and the moisture absorption rate of the product are reduced, and when the thickness is preferably 0.02 to 0.15mm, the comprehensive performance of the product is optimal. According to example 1, the process was carried outIn examples 6 to 9, the parameters of the polyester spunbonded nonwoven fabric in the preparation process have influence on the fiber areal density and the thickness of the finished product, and when the fiber areal density of the polyester spunbonded nonwoven fabric is preferably 15 to 90g/m2And when the thickness of the fiber is preferably 0.1-0.35 mm, the comprehensive performance of the obtained product is optimal.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
