Abstract
The utility model relates to a biaxial aramid fiber stitch-bonded fabric. At present, the aramid fabric in China mainly takes low-gram-weight aramid plain cloth, aramid unidirectional cloth, aramid non-woven fabric and combined aramid cloth as main materials, and cannot thoroughly meet market requirements in weaving structure and performance. The utility model discloses its characterized in that comprises one deck warp direction fibrous layer and one deck latitudinal direction fibrous layer, warp direction fibrous layer in order to be positive 45 orientations with the warp direction and lay, latitudinal direction fibrous layer in order to be minus 45 orientations with the axial and lay, weave two-layer fibrous layer together through the stitch-bonding dacron silk and constitute an overall structure. The utility model discloses make the fabric cloth cover have the characteristic that is different from plain weave fabric, positive and negative 45 degrees direction tension is even, provides the possibility for satisfying the demand of the combined material product of certain positive and negative 45 degrees direction atress of needs.
Description
Technical Field
The utility model belongs to the technical field of novel material, a industrial textile is related to, in particular to biaxial fragrant wheel stitch-bonded fabric.
Background
With the development of the society and the continuous improvement of the industrial level, no matter in military or civil fields, the demand of China on novel high-technology fiber material fabrics is continuously improved, and the aramid fiber fabrics as novel woven fabrics with better mechanical characteristics, higher strength and more corrosion resistance are paid more attention to and applied by various industries. At present, the aramid fabric in China mainly comprises low-gram-weight aramid plain cloth, aramid unidirectional cloth, aramid non-woven cloth and combined aramid cloth, and cannot completely meet market requirements in terms of weaving structure and performance, so that the improvement and the upgrade of the process structure of the composite material reinforcement material are particularly important.
SUMMERY OF THE UTILITY MODEL
The utility model aims at promoting the limitation of aramid fiber stitch-bonded fabric in the structure atress side to provide a biaxial stitch-bonded fabric, have good mechanical properties and wider application space.
The utility model adopts the technical proposal that: the utility model provides a biaxial aramid fiber stitch-bonded fabric which characterized in that comprises one deck warp direction fibrous layer and one deck latitudinal direction fibrous layer, the warp direction fibrous layer in order to be positive 45 orientation with the warp direction and lay, latitudinal direction fibrous layer in order to be minus 45 orientation with the axial and lay, weave two-layer fibrous layer together through stitch-bonding dacron silk and constitute an overall structure.
The warp-wise fiber layer and the weft-wise fiber layer are aramid fibers.
The aramid fiber is aramid fiber yarn with the specification of 500D-1500D.
The density of the warp fiber layers is 20-25/inch, and the unit weight of the fibers is 150-500 g.
The aramid fiber is aramid fiber yarn with 800D specification.
The utility model discloses neither be different from ordinary fabric, also be different from the felt of normal meaning, but one deck warp overlaps together with one deck woof, and warp, woof and warp direction and axial are positive and negative 45 orientations and lay, then bind technology through the stitch-bonding polyester yarn and weave two-layer yarn layer and constitute an overall structure together.
The utility model relates to a can give the technological structure of the sufficient tensile strength of fabric and tensile modulus at positive and negative 45 degrees directions, use the yarn to overlap the multilayer structure as main laying mode simultaneously, make the fabric cloth cover have the characteristic that is different from plain weave fabric, positive and negative 45 degrees direction tension is even, provides the possibility for satisfying the demand of the combined material product of certain positive and negative 45 degrees direction atress of needs.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The multi-layer weft insertion stitch-bonded fabric of the present invention will be described in detail with reference to the accompanying drawings:
as shown in fig. 1, the utility model uses 800D high-strength aramid fiber yarn as warp-wise (+45 degree) fiber layer 1, the density is not less than 25 pieces/inch, and the unit weight of the fiber is 124 g; the lower layer takes 800D high-strength aramid fiber yarn as a weft (-45 degrees) fiber layer 2, and the weight of the fiber unit area is 124 g; and then the yarn is sewn and knitted into a whole by the low-elasticity polyester yarn, and the weight of the product per unit area is 255 g.
The utility model relates to a can give the technological structure of the sufficient tensile strength of fabric and tensile modulus at positive and negative 45 degrees directions, use the yarn to overlap the multilayer structure as main laying mode simultaneously, make the fabric cloth cover have the characteristic that is different from plain weave fabric, positive and negative 45 degrees direction tension is even, provides the possibility for satisfying the demand of the combined material product of certain positive and negative 45 degrees direction atress of needs.
The above description is only an example of the present invention, and the present invention is not limited to the above example, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
