Technical Field
The utility model relates to the technical field of non-woven fabrics, in particular to a degradable non-woven fabric.
Background
The non-woven fabric has no warp and weft, is very convenient to cut and sew, and is used on daily life cloth and industrial cloth. In order to better protect the environment and avoid the damage to soil ecology caused by the characteristics of the non-woven fabric, the existing non-woven fabric is made of degradable materials.
However, when the degradable material is used, the overall physical properties of the non-woven fabric are lost, in particular the tensile resistance of the non-woven fabric is reduced, and the floating filaments are easily caused.

Aiming at the defects in the prior art, the utility model aims to provide the degradable non-woven fabric which is strong in tensile strength, convenient to degrade and environment-friendly.
In order to realize the purpose, the utility model provides the following technical scheme:
a degradable nonwoven fabric comprising:
a base layer; which is made of bamboo fiber, the base layer is provided with two layers which are in an up-and-down relationship and are a top surface layer and a bottom surface layer,
the degradable layer, this degradable layer is arranged in the basal layer, and the degradable layer includes first polylactic acid fibrous layer and second polylactic acid fibrous layer, and first polylactic acid fibrous layer comprises complex root first cellosilk laminating on the top surface layer, and second polylactic acid fibrous layer comprises complex root second cellosilk laminating on the bottom surface layer, and first cellosilk and second cellosilk are the cross and arrange.
The utility model is further configured to: the top surface layer is formed by a plurality of first bamboo fiber yarns in transverse arrangement, and the bottom surface layer is formed by a plurality of second bamboo fiber yarns in longitudinal arrangement.
The utility model is further configured to: the first fiber yarns are obliquely arranged at an angle of 45 degrees relative to the top surface layer, and the second fiber yarns are obliquely arranged at an angle of 45 degrees relative to the bottom surface layer.
The utility model is further configured to: the top surface layer, the first polylactic acid fiber layer, the second polylactic acid fiber layer and the bottom surface layer are sequentially compounded through hot pressing.
Compared with the defects of the prior art, the utility model has the beneficial effects that:
1. the non-woven fabric is formed by combining bamboo fibers and polylactic acid fibers, so that the non-woven fabric has corresponding antibacterial and environment-friendly performances while being used for the ecological degradation function.
2. The fiber layers are hot-pressed and compounded in a staggered arrangement mode, so that the physical performance of the non-woven fabric can be greatly improved, the structure is kept stable when the non-woven fabric is subjected to corresponding pulling force, and the condition of floating filaments is avoided.

Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 5.
The specific structure of this embodiment includes:
the base layer is made of bamboo fibers, and the degradable layer is made of polylactic acid fibers.
Bamboo fiber: has natural antibacterial and bacteriostatic ability, and has strong air permeability and instant water absorption ability.
Polylactic acid fiber: the starch-containing agricultural products such as corn, wheat and beet are used as raw materials, and are fermented to generate lactic acid, and then the lactic acid is subjected to polycondensation and melt spinning to prepare the starch-containing synthetic fiber which is a raw material which can be planted and is easy to plant, and wastes can be naturally degraded in nature.
Wherein the base layer comprises a top layer 11 and a bottom layer 12. The top layer 11 and the bottom layer 12 are in an up-down relationship. The top layer 11 is formed by a plurality of first bamboo filaments 31 arranged transversely, and the bottom layer 12 is formed by a plurality of second bamboo filaments 32 arranged longitudinally.
The degradable layer is placed within the base layer, i.e. between the top layer 11 and the bottom layer 12.
The degradable layer comprises a first polylactic acid fiber layer 21 and a second polylactic acid fiber layer 22.
The first polylactic acid fiber layer 21 is formed by attaching a plurality of first fiber yarns 41 to the top surface layer 11;
the second polylactic acid fiber layer 22 is formed by attaching a plurality of second fiber yarns 42 on the bottom surface layer 12;
the first fibers 41 are arranged at an angle of 45 ° with respect to the top layer 11, and the second fibers 42 are arranged at an angle of 45 ° with respect to the bottom layer 12. The first fiber filaments 41 and the second fiber filaments 42 are arranged in a crossing manner.
The top layer 11, the first polylactic acid fiber layer 21, the second polylactic acid fiber layer 22 and the bottom layer 12 are sequentially compounded by hot pressing. The fiber yarn arrangement directions of the top surface layer 11 and the bottom surface layer 12 are in a vertical relation, so that the two layers are combined to ensure the tensile property in oblique pulling.
The fiber filament arrangement directions of the first polylactic acid fiber layer 21 and the second polylactic acid fiber layer 22 are in a cross-perpendicular relationship, so that the two layers are combined to ensure the tensile strength during forward pulling. After the four fiber layers are combined, the tensile capacity of the whole fiber yarn can be ensured.
When the fiber is pulled from four directions, the endurance generated by different directions of each layer of fiber can ensure the stability of the whole structure, and the generation of the floating fiber caused by local fracture is avoided.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art should be able to make general changes and substitutions within the technical scope of the present invention.
