Abstract
The utility model relates to fibrilia non-woven composite wall cloth. The fibrilia non-woven composite wall cloth provided by the utility model comprises a fibrilia non-woven layer, wherein one other-fiber layer is composited on one surface of the fibrilia non-woven layer; and the other-fiber layer is used as an appearance surface. According to the utility model, one other-fiber layer is composited on one surface of the fibrilia non-woven layer, and the other-fiber layer is used as the appearance surface; and by virtue of the structural design, short fiber which easily drops out of the fibrilia non-woven layer is composited in the interior of the whole wall cloth by the other-fiber layer and does not easily drop off, thereby avoiding the defect that in the prior art, the short fiber is easy to drop when a single fibrilia non-woven layer is used as the wall cloth, so as to influence the cleanliness of indoor environment.
Description
Technical field
The utility model relates to a kind of wall paper, is specifically related to a kind of flax fibre nonwoven composite wall cloth.
Background technology
Along with people's is decorated improving constantly of requiring to indoor wall, and the bast fiber nonwoven fabric wall paper has been come into people's the visual field gradually.
Chinese patent document CN2753779Y discloses a kind of crudefiber crop decorative wall cloth, and its wall paper is made up of base material and the surface decoration layer that is positioned on the said base material, and said surface decoration layer and said base material glued joint in one; Said surface decoration layer is the flax fibre layer.Owing to will realize the combination between base material and the hemp fabric; And the combination of multilayer material in the base material, need be between said base material and hemp fabric, and between the base material multilayer material adhesive is set; The adhesive major part is an organic substance, can pollute indoor air environment.
For overcoming this defective, Chinese patent document CN101935917A discloses a kind of flax fibre wall paper, and it is made up of single bast fiber nonwoven fabric layer.Wall paper in the document owing to adopted single bast fiber nonwoven fabric layer, has overcome that available technology adopting binding agent compound noon on base material is spun layer of cloth and harmful effect that environment is caused.But; Because flax fibre is crisp, hard, in the process of producing bast fiber nonwoven fabric, can produce a large amount of flax fibre staple fibres, make a large amount of staple fibres of content in the flax fibre wall paper; These flax fibre staple fibres in use can come off from the flax fibre wall paper, thereby influence the cleaning of indoor environment.
The utility model content
Therefore, the single flax fibre nonwoven wall paper that the technical problem that the utility model will solve is to overcome in the present technology influences the defective of indoor environment cleaning, thereby a kind of flax fibre nonwoven composite wall cloth that is easy to keep the indoor environment cleaning is provided.
For this reason, the utility model provides a kind of flax fibre nonwoven composite wall cloth, comprises the flax fibre nonwoven layers, compound other fibrages on the surface of said flax fibre nonwoven layers, and said other fibrages are as appearance.At this, said other fibrages are meant by other the fibroplastic fibrages except that flax fibre.
Preferably, said other fibrages are the chemical fibre layer.
Preferably, said other fibrolaminar grammes per square metres are 5-300g/m
2
Further preferably, said other fibrolaminar grammes per square metres are 10-50g/m
