Abstract
The invention discloses a nonwoven material for wall decoration, which comprises a polyester filament non-woven fabric substrate layer and a coating layer on at least one surface of the substrate layer, wherein the surface evenness of the material is 1-10 mu m, and the effective width of the material is 2.8-3.1 m. The nonwoven material for wall decoration has the characteristics of good water resistance, vivid printing effect and seamless adhesion.
Description
Technical Field
The invention relates to a nonwoven material for wall decoration.
Background
Wall decoration materials such as wallpaper, wall cloth and the like are paper or cloth sheet-shaped base materials attached to the inner walls and ceilings of buildings and the like, and mainly play roles in preventing wall mildew and decoration.
However, most of wallpaper materials in the current market are paper materials, so that the wallpaper materials have low strength and poor waterproof effect, and cannot be made into wide-width materials. The clean height of the common house in China family is 2.6-3.2 m, and the wallpaper material in the market is narrower in width, so that joints can be generated when the common house is attached, the joints are easy to warp, the attractiveness can be affected, and the joints have no protection effect on the wall.
In addition, the seamless wall cloth materials appearing on the market at present mainly comprise woven fabrics and non-woven fabrics, and most of the seamless wall cloth materials are manufactured by laminating fabrics and spunlaced non-woven fabrics, and can meet the requirement of wide width, but the waterproof performance of the materials is general, and compared with the wallpaper materials, the patterns of the wall cloth are single, and the color patterns are not rich. Moreover, since the surface flatness cannot be as flat as paper, the printing effect is poor, and thus, the favorite shape and pattern cannot be freely selected. In addition, because the wall cloth has heavier gram weight and thicker thickness, the construction difficulty can be correspondingly increased, and the trace can be obvious at the unavoidable joint, thereby influencing the appearance. On the other hand, the elongation rate of the wall cloth material prepared by laminating the fabric and the spunlaced non-woven fabric is generally large, and when the wall cloth material is in laminating construction, the stretching elongation can lead to deformation and elongation of the cloth surface pattern, so that the pattern distribution is irregular, and the attractiveness is influenced.
Aiming at the problems of wall decoration materials such as wallpaper wall cloth, product developers are also continuously exploring good solutions, such as Chinese patent publication No. CN104141370A discloses a wide digital printing polyester wall cloth, which is prepared by padding materials with waterproof finishing agents to ensure that the materials have good waterproof and oil-proof effects, but the polyester wall cloth is formed by common fabrics, has great restrictions on colors and patterns, has overlarge product thickness and large elongation, is easy to deform in pasting construction, has no excellent water pressure resistance, and has a certain bottleneck on the protection effect of the wall surface.
As another example, chinese patent CN108505216a discloses a method for producing a spun-bonded nonwoven fabric of polyester filaments, which solves the problem of product strength, but the material has poor surface flatness due to the adoption of the needling reinforcement mode, does not have good printing effect, and has poor concealment due to no processing such as compounding.

Detailed Description
The nonwoven material for wall decoration comprises a polyester filament nonwoven fabric substrate layer and a coating layer on at least one surface of the substrate layer, wherein the surface flatness of the material is 1-10 mu m, and the effective width of the material is 2.8-3.1 m. The base material layer is formed by polyester filament non-woven fabrics, and the aperture of the obtained base material is smaller due to the adoption of the polyester filament non-woven fabrics with fine fineness, so that fine water drops can be blocked, and the prepared non-woven material for wall decoration has excellent waterproof performance. In addition, due to the filament structure, when the prepared base material is acted by force, entanglement, slippage and falling off among fibers are not generated, so that the strong performance of the base material is better. The gram weight of the polyester filament non-woven fabric substrate layer is preferably 50-200 g/m 2 If the gram weight of the polyester filament non-woven fabric substrate layer is too low, the prepared non-woven material for wall decoration is too light and thin, the strength is limited to a certain extent, and when at least one surface of the substrate contains a coating layer, the coating layer processing needs great engineering tension, so that the substrate layer with too low gram weight has the hidden trouble of breakage; if the gram weight of the polyester filament non-woven fabric substrate layer is too high, the prepared non-woven material for wall decoration is too thick and too hard, the package material cannot be spread flatly after being unfolded, andeven after spreading, the difficulty of the wall surface pasting construction is greatly increased due to the large width during the seamless pasting and the too thick material.
The substrate layer of the invention is provided with a coating layer on at least one surface, and the purpose of the coating layer is to improve the shielding property of the material and endow the material with certain functionality. The coating agent on the coating layer is preferably polyacrylate, polyurethane or polyvinyl chloride, wherein the polyacrylate coating agent is a polymer formed by copolymerizing polyacrylate, methyl polyacrylate and other unsaturated monomers, the hardness degree of the polyacrylate coating agent can be adjusted according to the composition proportion, and the polyacrylate coating agent has the advantages of softness, dry cleaning resistance, wear resistance, aging resistance and the like, also has good light heat resistance, and can be subjected to foaming coating processing, so the coating agent on the coating layer is more preferably polyacrylate. In addition, in order to make the nonwoven material for wall decoration of the present invention have a certain functionality, a functional finishing agent such as water-proof, flame-retardant, formaldehyde-removing, antistatic, antibacterial, antifouling, wear-resistant, negative ion and the like may be further added to the coating agent.
The surface evenness of the nonwoven material for wall decoration is 1-10 mu m, the common textile material comprises nonwoven materials, the surface evenness is more than 15 mu m, if the surface of the material is uneven, the surface of the material has a plurality of water storage pores, so that the water resistance of the material is poor, in addition, the printability of the material is poor due to the uneven surface of the material, the pattern is printed, and the pattern effect is greatly reduced. The substrate layer is formed by polyester filament non-woven fabrics, and the performance and the surface flatness of the prepared non-woven material for wall decoration are greatly improved by adopting resin raw materials with narrow molecular weight distribution and a special process. The special process adopts a smooth roller method, the surface of the material is free of rolling points and embossing, so that the surface of the material is smooth like a film, the smooth roller can be made of a steel roller or a rubber roller, and the smooth roller has certain elasticity due to high friction force of the rubber roller and can be matched with the steel roller for use, and the flatness can be optimized. In general, the material of the spun-bonded non-woven fabric is composed of polypropylene filaments, and when the spun-bonded non-woven fabric is reinforced, the polypropylene material is soft and easy to form a film, so that in order to ensure the air permeability of the spun-bonded non-woven fabric, only the reinforcing and forming can be performed by adopting a rolling point embossing or needling and water needling mode, and the result is uneven surface of the material. The flatness of the nonwoven material for wall decoration must be controlled within a certain range, if the surface flatness of the nonwoven material is less than 1 mu m, the surface of the material is very compact, so that the air permeability of the material is greatly reduced, and gas can not escape during use, thereby causing the phenomenon of foaming on the surface of the nonwoven material; if the surface evenness of the nonwoven material is more than 10 μm, there are very many water-storing pores on the surface of the material, resulting in poor water repellency of the material, and in addition, the printability of the material is deteriorated due to the unevenness of the surface of the material, the pattern is printed, and the pattern effect is not realistic. In view of the realistic printing effect and excellent water repellency of the nonwoven material for wall decoration of the present invention, the nonwoven material preferably has a surface evenness of 3 to 7. Mu.m, more preferably 4 to 6. Mu.m.
The effective width of the nonwoven material for wall decoration is 2.8-3.1 m, and the nonwoven material can be subjected to mass production processing with large width and is applied to seamless wallpaper. The legal requirements of the layer height of the Chinese family house are above 2.7m, and the allowance of the trimming and alignment is considered, so that the effective width of the material is above 2.8 m; the visibility of the naked eyes is 124 degrees, but the part exceeding 30 degrees can be called the afterlight of the sight, the optimal ornamental visibility is 10-20 degrees, if the length and width directions are both beyond the optimal visibility range of the human eyes, the naked eyes can be tired due to frequent rotation when the patterns of the wall cloth are appreciated, and the eyesight is affected, so that the effective width of the material is required to be below 3.1m. If the effective width of the nonwoven material is higher than 3.1m, people can easily feel tired when watching patterns, and meanwhile, the difficulty of production, transportation and construction of the material can be greatly improved.
The coating layer preferably contains 5 to 50% by weight of titanium dioxide powder. Titanium dioxide is commonly called titanium dioxide, and can be classified into anatase type titanium dioxide and rutile type titanium dioxide according to the crystal form, wherein the anatase type titanium dioxide powder has higher whiteness and better concealment, and the stability of the anatase type titanium dioxide is enough to meet the use requirement when the titanium dioxide is used indoors, so the titanium dioxide powder in the coating layer is preferably the anatase type titanium dioxide powder. The titanium dioxide powder content in the coating layer of the present invention is preferably 5 to 50% by weight. When the content of the titanium dioxide powder reaches more than 5%, the light shielding effect of the material is obviously improved, and the shielding effect is better when the content is more; however, for coating processing, most importantly, the uniformity and stability of processing are also a critical factor, and when the content of titanium dioxide powder is below 50%, the content of the glue in the coating layer is dominant, so that the uniformity and firmness of the coating processing can be ensured. The titanium dioxide powder content of the present invention is more preferably 15 to 40% by weight in view of the concealment of the nonwoven material of the present invention and the uniformity and fastness of the coating process. The coating method of the present invention is preferably a doctor blade coating method.
The viscosity average relative molecular weight of the polyester filaments constituting the polyester filament nonwoven fabric substrate layer is preferably 35000 to 45000. The viscosity-average relative molecular weight also determines the strength of the obtained fiber to a great extent, the relative molecular weight makes the polymer show different properties, only a melt with proper viscosity can spin the polyester filament with excellent strength, and the viscosity-average relative molecular weight plays an extremely important role in determining the melt spinning characteristic of the polymer and the mechanical property of the spun fiber, and can characterize the viscosity of the polymer melt and the relative molecular weight distribution to a certain extent. The viscosity flow of the polymer is greatly influenced by the viscosity-average molecular mass of the polymer, and the increase of the viscosity-average molecular mass can cause the sharp increase of apparent viscosity and the great reduction of melt index, so that the polymer cannot be normally spun or the spinning diameter cannot be controlled. If the viscosity-average molecular weight of the polyester filaments constituting the polyester filament nonwoven fabric substrate layer is too large, drawing during spinning becomes difficult, the spinning diameter becomes too large, the desired fine fineness cannot be achieved, the pores of the obtained material become large, and the water resistance becomes poor; if the viscosity-average molecular weight of the polyester filaments forming the polyester filament non-woven fabric substrate layer is too small, the fiber strength is reduced, and the strength of the prepared substrate is also reduced, so that the material has potential safety hazards of breakage during subsequent processing and construction use.
The diameter of the polyester filaments constituting the polyester filament nonwoven fabric substrate layer is preferably 5 to 20. Mu.m. The finer the diameter of the polyester filament yarn is, the smaller the aperture is, and the better the waterproof performance of the obtained base material is, but if the diameter of the polyester filament yarn is too thin, the draft ratio during spinning is greatly increased, the uniformity of the fiber is reduced, weak knots are generated, and the strength of the obtained base material is greatly reduced; on the other hand, although the improvement of the fiber diameter can improve the strength of the material and ensure the normal production and use of the material when the width is larger, if the diameter of the polyester filament yarn is too large, the pore diameter of the obtained base material becomes large, fine water drops easily pass through the material, so that the water resistance is affected, and meanwhile, if the diameter is too large, the bending rigidity of the fiber is also increased, the bending after the fiber reinforcement is easily restored, and the smoothness of the surface is deteriorated due to the concave-convex effect. The average diameter of the polyester filaments of the present invention is more preferably 12 to 18 μm in view of the water repellency, printability of the base material layer and securing the strength of the material.
The surface evenness of the polyester filament yarn non-woven fabric substrate layer is preferably 3-7 mu m. The surface flatness of the substrate layer is also critical, if the flatness of the polyester filament non-woven fabric substrate layer is too low, the film forming phenomenon of the surface is necessarily caused to a certain extent, the ventilation degree of the material is reduced, so that the problems of air bubbles and the like are easily generated during construction are caused, moreover, if the surface flatness of the substrate layer is too high, the surface of the obtained non-woven material for wall decoration is in a rough state after coating processing, if the flatness is improved through coating processing, the coating amount of the coating layer is increased, and the ventilation degree of the final non-woven material is reduced. The surface smoothness of the polyester filament nonwoven fabric substrate layer of the present invention is more preferably 4 to 6 μm in view of the smoothness and breathability of the final nonwoven material.
The coating amount of the coating layer is preferably 30 to 200g/m 2 . The invention preferably uses a doctor blade coating method to process the coating, if the coating amount of the coating layer is too low, uneven coating can be easily caused, uneven surface of the material can be caused, when the surface of the prepared material is uneven, the obtained nonwoven material is applied to wall decoration materials, the printability of the material is poor and the concealment is reduced due to uneven surface and uneven coating; if the coating amount of the coating layer is too high, it is easy to cause the surface of the base material layer to contain too much coating agent, the coating agent is too thick, the surface is dried but the inside is not completely dried, then when the inside is dried, gas is difficult to escape, and at this time, the dried part of the surface is foamed, so that the drying is uneven to cause foaming. In addition, when the prepared base material layer is coated with excessive paint, the obtained nonwoven material is applied to wall decoration materials, and the problem of foaming is easy to occur, so that the surface of the material is uneven, and the appearance is influenced; and too large coating amount can reduce the air permeability of the nonwoven material, which can cause the problems of no dissipation of water vapor in the wall surface, mold and the like. In view of the excellent water repellency of the nonwoven material for wall decoration of the present invention, the coating amount of the coating layer is preferably 40 to 100g/m 2 More preferably 45 to 70g/m 2 。
The gram weight of the nonwoven material for wall decoration is preferably 100-400 g/m 2 The thickness is preferably 0.15 to 0.30mm. The gram weight of the material is closely related to the strength and concealment of the material, when the gram weight of the material is low, the strength of the material is correspondingly reduced, when the gram weight is high, the air permeability of the material is reduced, the hardness of the material is also increased, and when the wall surface is adhered to the thick and difficult-to-spread material, the construction difficulty is very high. Therefore, the nonwoven material of the present invention is more preferably 120 to 300g/m in gram weight 2 Further preferably 150 to 200g/m 2 . The thickness variation range and gram weight of the material are consistent, and the nonwoven material has better surface evenness and relatively higher thickness compared with common textile fabric and spunlaced nonwoven materialThe nonwoven material of the present invention preferably has a thickness of 0.18 to 0.28mm, more preferably 0.20 to 0.25mm.
The strength of the nonwoven material for wall decoration of the present invention is preferably 50 to 500N/5cm. If the strength of the nonwoven material is too low, the nonwoven material is extremely easy to damage when being subjected to large-width wall surface pasting processing; if the strength of the nonwoven material is too high, the hardness, thickness and gram weight of the material are correspondingly increased, and if the pasting processing is carried out on a flat wall surface, the construction difficulty and the fastness requirements on glue are increased, and the strength of the nonwoven material for wall decoration is preferably 100-400N/5 cm.
The elongation of the nonwoven material for wall decoration of the present invention is preferably 2 to 20%. If the elongation of the nonwoven material is too low, the toughness and energy absorbing capacity of the material is also low, i.e., commonly known as "brittle" materials, which are very susceptible to breakage and breakage upon impact; if the elongation of the nonwoven material is too high, the material is correspondingly easy to deform, which can cause deformation of the printed pattern on the surface of the material in the processes of production, transportation, construction and use, no matter which engineering is stressed unevenly. Therefore, the elongation of the nonwoven material for wall decoration of the present invention is more preferably 5 to 18% in view of maintaining the toughness and the pattern of the material without deformation.
The nonwoven material for wall decoration has good waterproof property, can play a good role in protecting a wall surface, has the water pressure resistance of 50-500 mm water column, has poor waterproof property when the water pressure resistance of the nonwoven material is too low, and cannot play a sufficient role in protecting the wall surface; when the water pressure resistance of the nonwoven material is too high, the pore diameter of the material and the fineness of the fiber are correspondingly reduced, and the gram weight of the material is increased and the air permeability is reduced, so that the workability is affected. The nonwoven material for wall decoration of the present invention is more preferably 100 to 300mm water column in terms of the water repellency of the nonwoven material and the workability of the material.
The transparency of the nonwoven material for wall decoration reaches 92-100%, the better the transparency is, the better the effect of the material on covering stains on the original wall is, and the transparency of the nonwoven material is more preferably 95-100%.
The nonwoven material for wall decoration of the present invention may further comprise a printed working layer. The printed pattern may be selected according to market demand or user demand. The printing processing layer can be arranged on the coating surface layer or the substrate layer.

TABLE 2
。
From the above table, (1) it is clear that, under the same conditions, the smaller the surface flatness of the nonwoven material in example 2, the better the printing effect of the nonwoven material for wall decoration, but the film forming phenomenon occurs on the surface, the workability is moderate, and the surface flatness of the nonwoven material in example 1 is in the preferable range, and the obtained nonwoven material for wall decoration has good printing effect and excellent workability.
(2) As is clear from examples 1, 4 and 5, the polyester filaments constituting the polyester filament nonwoven fabric base layer in example 5 had a viscosity average relative molecular weight and a polyester filament diameter not within the preferred ranges under the same conditions, and the nonwoven fabric obtained in example 5 had a slightly lower strength due to a slightly lower molecular weight, and was moderate in workability.
(3) As is clear from examples 6 and 7, the coating amount of the coating layer in example 6 was in the preferable range under the same conditions, and the resultant nonwoven material was excellent in permeation resistance and printing effect as compared with the latter.
(4) As is clear from examples 8 and 9 and example 13, under the same conditions, the titanium dioxide content in the coating layer in example 13 was not within the preferred range, and the resulting nonwoven material was low in permeation resistance, i.e., moderate in hiding effect.
(5) As is clear from example 1 and comparative example 1, the nonwoven material of comparative example 1 had too high surface flatness, and the nonwoven material had lower water resistance, i.e., the material had poor water repellency, and had poor printing effect, as compared with the former.
(6) As is clear from example 1 and comparative example 2, under the same conditions, the base material layer in comparative example 2 was formed of a wet laid nonwoven fabric, and the obtained nonwoven material was low in strength, and was narrow in width, easy to break, poor in workability, unable to be applied without seams, and low in water resistance, i.e., poor in water resistance.
(7) As is clear from examples 1 and 3, under the same conditions, the nonwoven material of comparative example 3 has too small effective width, and the material cannot be adhered to the wall surface without any seam, which results in easy warping at the seam of the material and reduced service life.
