Embodiment Construction

[0030] Such as Figure 1 to Figure 5 As shown, the spunbonded pulp nonwoven fabric of the present invention includes a three-layer structure bonded together by heat and pressure; the first layer 1 and the third layer 3 are both spunbonded nonwoven material layers, as the second layer of the middle layer Layer 2 is a cellulose fiber layer;

[0031] The first layer of spunbond nonwoven material layer is meltblown nonwoven fabric (M), spunbond nonwoven fabric (S) or meltblown spunbond composite nonwoven fabric, and meltblown spunbond composite nonwoven fabric is SMS or MSM or MS or SM;

[0032] The second layer 2, ie, the cellulose fiber layer, is a mixture of cellulose fiber pulp and hot-melt fibers.

[0033] The grammage of the spun-bonded non-woven material layer of the first layer is 8-60 g / m2 (both values ​​8 and 60 are included) and the thickness is 0.1-1 mm.

[0034] The cellulose fiber pulp is wood pulp short fiber after crushing and opening. In the present invention,...

Abstract

The invention discloses a spunbonded pulp non-woven fabric. The spunbonded pulp non-woven fabric comprises three layer structures which are bonded together by hot pressing; the first layer and the third layer are spunbond non-woven material layer, and the second layer as an intermediate layer is cellulose fiber layer; the spunbonded non-woven material layer of the first layer is melt-blown non-woven fabric, spunbonded non-woven fabric or melt-blown spunbonded composite non-woven fabric, and the melt-blown spunbonded composite non-woven fabric is an SMS or an MSM or an MS or an SM; the second layer, the cellulose fiber layer, is a mixture of cellulose fiber pulp and hot melt fiber. The cellulose fiber pulp is compounded with the melt-blown non-woven material through the hot melt fiber, comparing with the cellulose fiber is firstly prepared, the cellulose fiber is compounded with the melt-blown non-woven material through spunlace process, the loss of the wood pulp short fiber is avoided,and the process is simpler, the production is more convenient, the cost is lower, while the same hydrophilic and oleophilic property is ensured, the competitiveness of the product can be greatly improved, and the produced non-woven fabric is used for manufacturing the wiping cloth.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a lipophilic and hydrophilic nonwoven fabric. Background technique [0002] The spunlace nonwoven process is called spunlace or hydroentangling. The spunlace nonwoven process is to continuously spray the fiber web through high-pressure water flow, and under the action of hydraulic force, the fibers in the fiber web can be moved, displaced, rearranged and entangled with each other, so that the fiber web can be reinforced to obtain certain physical and mechanical properties. [0003] In the United States, popular industrial wiping cloths are generally made of polypropylene spunbonded nonwovens and wood pulp fibers by spunlace. The hydroentanglement process entangles shorter wood pulp fibers evenly and tightly around the spunbond filaments, making them both strong and absorbent. [0004] However, in the series of wood pulp spunlace nonwovens, there is an unavoidable problem, that...
