Technical Field
The invention relates to the field of papermaking, in particular to a preparation method of non-woven fabric based on carding and spunlace.
Background
Patent CN110524984A provides a method for preparing three-layer nonwoven fabric, but the method for preparing three-layer nonwoven fabric is fixed together by using water jet, but the method for fixing has the following defects: the intensity is not enough after fixing promptly, still need dry during the use, so the energy consumption of whole preparation process is higher relatively, and because rely on drying to bond the three together, so fall the dirt easily in the use.
Disclosure of Invention
Aiming at the problems, the invention provides a preparation method of non-woven fabric based on carding and spunlace.
The technical scheme adopted by the invention is as follows:
a preparation method of non-woven fabric based on carding hydro-entangled comprises the following steps,
compounding: firstly, compounding a first fiber layer on the base fabric, and then compounding a second fiber layer on the first fiber layer;
a forming step: carrying out spunlace after the compounding is finished, and carrying out squeezing after the spunlace is finished;
gluing: after pressing is complete, the adhesive coats the second fibrous layer and the base fabric.
The base fabric, the first fiber layer and the second fiber layer are bonded together through the adhesive, so that compared with hot welding, the wear resistance of the whole non-woven fabric is enhanced due to the fact that the adhesive is coated outside the non-woven fabric, and dust is not prone to falling off in the using process.
Optionally, the base fabric is a PLA spunbonded hot-rolled fabric or a PP spunbonded hot-rolled fabric or a PBAT hot-rolled fabric.
Optionally, the hydroentangling comprises platform hydroentangling.
The effect of the platform hydroentangling is to entangle the base fabric, the first fibrous layer and the second fibrous layer together.
Optionally, the hydroentangling further comprises circular drum hydroentangling.
The whole spunlace process comprises two operation processes of platform spunlace and round drum spunlace, wherein the platform spunlace is carried out at present, the three layers are entangled together, then the round drum spunlace is carried out, patterns are pressed on the whole non-woven fabric, and the composite strength between the three layers is further improved. And the rolling is carried out after the water jet so as to squeeze out the water and control the thickness of the whole non-woven fabric.
Optionally, the adhesive during gluing is PVA or polyacrylic acid emulsion, and the addition amount of the adhesive is 0.1-1% of the total weight of the base fabric, the first fiber layer and the second fiber layer.
PVA and polyacrylic acid emulsion adhesive belong to water-based adhesive, and after the adhesive is coated on the whole non-woven fabric, the whole non-woven fabric has good wear resistance.
Optionally, the first fiber layer is one or more of a plant fiber or a chemical fiber.
The specific plant fiber can be grass fiber, wood pulp fiber or bamboo pulp fiber, the chemical fiber can be viscose fiber, and the whole first fiber layer can be one or more of the fibers.
Optionally, the second fiber layer is a PP fiber, a PET fiber, an ES fiber, a Rayon fiber, a PBAT fiber, or a PLA fiber.
Optionally, the second fibrous layer is carded on top of the first fibrous layer by means of a carding machine.
The second fiber layer can be directly laid on the first fiber layer or alternatively, the second fiber layer can be cross-laid on the first fiber layer.
Optionally, the first fibrous layer is laid on the base fabric by a wet process.
The first fibrous layer adopts the wood pulp fibre that wet process papermaking technology laid, and the second fibrous layer adopts carding PP fibre (or other similar fibre), because the second floor fibre is the fibre that length is longer relatively, so monoblock non-woven fabrics has good tensile properties, is difficult for being dragged the fracture.
Optionally, the second fiber layer has one and only one layer, and the second fiber layer has one and only one layer.
The invention has the beneficial effects that: the non-woven fabric prepared by the method has good wear resistance, and dust can not fall off in the using process; and has good tensile capacity and is not easy to be broken.
