Description

Down needled non-woven felt Technical Field The application relates to the technical field of felts, in particular to a down needled non-woven felt. Background Felt materials are now commonly used as fabrics in people's life because of their strong elasticity, wear resistance and good strength, and different felts can be combined from different materials according to different use scenarios. The fiber felt material is shaped after being mutually intertangled and glued, is convenient to cut, and has relatively uniform plane distribution. In the production process of the down needled non-woven felt, feathers or down is usually stuck between cloth materials by using viscose, but the adhesive strength between the materials cannot be ensured by using a viscose sticking method, delamination easily occurs after long-time use, and the softness of a finished product is reduced by using the down needled non-woven felt formed by viscose adhesion because of the intervention of viscose, and the comfort and the use feeling are reduced. Disclosure of utility model In order to improve the comfort of the down needled non-woven felt in the use process, the application provides the down needled non-woven felt. The application provides a down needled non-woven felt, which adopts the following technical scheme: The utility model provides a down needled non-woven felt, includes first layer first connection bed, second layer presss from both sides the bed and third layer second connection bed, press from both sides the bed setting and be in first connection bed with between the bed is connected to the second, first connection bed the press from both sides the bed with the layer is connected the three-layer in total and is utilized the needled technology processing entanglement to connect. Through adopting above-mentioned technical scheme, adopt thorn to puncture to first connection bed of material, clamp bed of material and second connection bed of material repeatedly, be convenient for first connection bed of material, clamp bed of material and second connection bed of material three-layer material quick bonding together fix, adopt the nonwoven goods of acupuncture processing, the finished product binding property is good, has stronger fastenability, and feel plump firm, easily tailors, the homogeneity is good, goods stable in structure, thermal insulation performance is good. In a specific embodiment, the first tie-layer can be a nonwoven, woven or yarn material. In a specific embodiment, the binder layer can be a down, feather or wool material. Through adopting above-mentioned technical scheme, when using the acupuncture processing to combine first connection bed of material and second connection bed of material, the soft material of eiderdown, feather or hair class can form the matte on the felt, and comfort and experience sense when reinforcing the use strengthen the thermal performance of felt simultaneously. In a specific embodiment, the second tie-layer can be a nonwoven, woven or yarn material. In a specific embodiment, the first connecting layer is provided with a first rib, and the first rib is disposed on a side close to the interlayer. Through adopting above-mentioned technical scheme, set up first bead on first joining material layer for the felting needle can collude more fibers when puncture first bead, increases fibrous entanglement quantity, reinforcing felt's intensity. In a specific embodiment, the first rib has a circular arc-shaped cross section. Through adopting above-mentioned technical scheme, set up first bead into the arc, when first connection bed of material and second connection bed of material are in the same place through the acupuncture, convex first bead is flattened to both sides easily for the processing felt that forms is difficult for having the arch, does not influence the leveling effect of felt again in the time of guaranteeing joint strength. In a specific embodiment, the second connecting layer is provided with a second rib, and the second rib is disposed on a side close to the interlayer.
