Abstract
The utility model discloses a stitch-bonded non-woven fabric, which comprises a hydrophobic short fiber net layer, a hydrophilic short fiber net layer and weft-knitted coils; the hydrophobic short fiber net layer is provided with a plurality of layers and is paved on the surface of the stitch-bonded non-woven fabric; the hydrophilic short fiber net layer is provided with a plurality of layers and is paved on the inner layer of the stitch-bonded non-woven fabric; the weft knitting coils comprise two strings of coils which are vertical to each other, and the two strings of weft knitting coils respectively sew and connect the hydrophobic short fiber net layer, the hydrophilic short fiber net layer and the adjacent hydrophilic short fiber net layer in two directions which are vertical to each other. The utility model relates to a stitch-bonded non-woven fabrics has good ductility and bursting strength.
Description
Technical Field
The utility model relates to a stitch-bonding non-woven fabrics.
Background
Stitching and knitting non-woven fabrics: the raw material is selected from high-quality plastic bottle sheets, processed to form recycled chemical fiber, and then subjected to stitch-bonding in a non-woven fabric process, wherein 80-95% of recycled polyester staple fiber and 5-20% of high-quality polyester filament yarn warp-knitted loop structure are used for reinforcing a fiber web, a yarn layer and a non-woven material (such as plastic sheets, plastic thin metal foils and the like) to form the RECYCLEDPET non-woven fabric.
In recent years, automobile ceiling fabrics are often made of stitch-bonded nonwoven fabrics, but warp-knitted loops are characterized by poor stretchability in the transverse direction, and although stitch-bonded nonwoven fabrics have good wear resistance and tear strength, they are poor in stretchability, hard in texture, and poor in burst strength.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a stitch-bonding non-woven fabrics replaces warp knitting coil with perpendicular crisscross weft knitting coil to this ductility and the bursting strength that improves the stitch-bonding non-woven fabrics.
In order to realize the purpose, the technical scheme of the utility model is a stitch-bonded non-woven fabric, which comprises a hydrophobic short fiber net layer, a hydrophilic short fiber net layer and weft-knitted coils; the hydrophobic short fiber net layer is provided with a plurality of layers and is paved on the surface of the stitch-bonded non-woven fabric; the hydrophilic short fiber net layer is provided with a plurality of layers and is paved on the inner layer of the stitch-bonded non-woven fabric; the weft knitting coils comprise two strings of coils which are vertical to each other, and the two strings of weft knitting coils respectively sew and connect the hydrophobic short fiber net layer, the hydrophilic short fiber net layer and the adjacent hydrophilic short fiber net layer in two directions which are vertical to each other.
Preferably, the hydrophobic short fiber net layer is made of hydrophobic polyester short fibers.
Preferably, the hydrophilic staple fiber web layer is made of hydrophilic regenerated fibers.
Preferably, the weft knitted loops are made of hydrophilic filaments.
The utility model discloses the top layer adopts hydrophobic short fiber, and the inlayer adopts hydrophilic short fiber, and when the surface was stained with water, water can not permeate the hydrophobic short fiber on top layer in, but the gathering gets up and flows into the inlayer from the mesh between the hydrophobic short fiber, and the hydrophilic short fiber of inlayer can aggravate the downflow that the top layer was stained with water, and final water is adsorbed in the hydrophilic short fiber of inlayer to make the stitch-bonding non-woven fabrics surface last drying. The weft-knitted loops have good stretchability in the loop arrangement direction, so that when the stitch-bonded non-woven fabric is partially jacked up, the stitch-bonded non-woven fabrics on two sides of the jacking position stretch downwards in a matched manner, and the stitch-bonded non-woven fabric has good bursting strength.
The utility model has the advantages and the beneficial effects that: the utility model relates to a stitch-bonding non-woven fabrics has good moisture absorption quick-drying performance, and the cloth cover can keep dry, and the stitch-bonding non-woven fabrics has good ductility and bursting strength.
