Description

Technical Field

[0001] The utility model relates to a wear-resistant cross-spunlace non-woven fabric, belonging to the technical field of non-woven fabrics. Background Art

[0002] The principle of water-entanglement reinforcement of fiber net is to use multiple fine water jets generated by high pressure - water-entanglement machine to spray fiber net. After the water jet passes through the fiber net, it is supported by the rebound of the net curtain and interspersed with the fiber net again. As a result, the fibers in the fiber net are displaced, interspersed, entangled and embraced under the hydraulic action of high-speed water jets interspersed in different directions, so that the fiber net is reinforced. Hemp fiber refers to the fiber obtained from various hemp plants, including bast fibers in the cortex of annual or perennial herbaceous dicotyledons and leaf fibers of monocotyledons. Hemp fiber has advantages that other fibers cannot match: it has good moisture absorption and dissipation and breathability, fast heat transfer and heat conduction, cool and crisp, sweating without sticking to the body, light texture, strong, insect-proof and mildew-proof, less static electricity, fabric is not easy to be polluted, soft and generous color, rough, suitable for human skin excretion and secretion. However, since hemp fiber is mainly bast fiber, and bast fiber is the basic skeleton of plants, it has a high degree of crystallinity and orientation, and the original fiber is distributed in a layered structure along the radial direction of the fiber. Therefore, hemp fiber has the fiber characteristics of high strength and low elongation. Hemp fiber is wear-resistant and can be used as a wiping material, but due to its high rigidity, it is only suitable for wiping stubborn oil stains. It also needs to be wiped with finer fiber non-woven fabrics, which need to be replaced frequently. The fiber web forming methods include parallel laying and cross laying, and cross laying can make the longitudinal and lateral strength of the product similar, avoiding the situation where the strength in one direction is smaller and affects the use of the non-woven fabric. How to prepare a wear-resistant cross spunlace non-woven fabric has become a problem to be solved. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] Combination Figure 1 The present embodiment is described in detail. The wear-resistant cross spunlace nonwoven fabric involved in the present embodiment comprises a first wear-resistant spunlace nonwoven fabric layer 1, a wood pulp PLA composite spunlace nonwoven fabric layer 2 and a second wear-resistant spunlace nonwoven fabric layer 3 compounded by hot melt adhesive.

[0022] The wood pulp PLA composite spunlace nonwoven fabric layer 2 includes a first wood pulp spunlace nonwoven fabric layer 21, a PLA spunbond nonwoven fabric layer 22 and a second wood pulp spunlace nonwoven fabric layer 23 that are spunlace-compounded; the wood pulp spunlace nonwoven fabric used in the first wood pulp spunlace nonwoven fabric layer 21 and the second wood pulp spunlace nonwoven fabric layer 23 has a good water absorption effect. In addition, since the PLA material in the PLA spunbond nonwoven fabric layer 22 has poor moisture absorption performance, the PLA spunbond nonwoven fabric has a certain waterproof effect and can prevent the flow of water on both sides for a short time. The first wood pulp spunlace nonwoven fabric layer 21 is close to one side of the first wear-resistant spunlace nonwoven fabric layer 1.

[0023] The first wear-resistant spunlace nonwoven fabric layer 1 and the second wear-resistant spunlace nonwoven fabric layer 3 are both cross-lapped fiber webs; the fiber web formed by the cross-lapped fiber web can reduce the difference in longitudinal and transverse strength between the first wear-resistant spunlace nonwoven fabric layer 1 and the second wear-resistant spunlace nonwoven fabric layer 3, and will not make the nonwoven fabric easily deformed in one direction.

[0024] The first wear-resistant spunlace nonwoven fabric layer 1 is a hemp fiber spunlace nonwoven fabric; the second wear-resistant spunlace nonwoven fabric layer 3 is a fine-denier nylon fiber spunlace nonwoven fabric. The hemp fiber used in this embodiment is ramie fiber, which has high rigidity, can wipe stubborn stains, and has good wear resistance. The nylon fiber spunlace nonwoven fabric used in the second hemp-resistant spunlace nonwoven fabric layer 3 also has wear resistance. And the fine-denier is used, which can be used in scenarios with high requirements for wiping materials.

[0025] Furthermore, the fine denier nylon fiber used in the second wear-resistant spunlace non-woven fabric layer 3 has a fineness of 0.8-1.5D, and the fineness used in this embodiment is 1.1D.

[0026] Embodiment 2

[0027] Combination Figure 3 , this embodiment is described in detail. The wear-resistant cross spunlace nonwoven fabric involved in this embodiment is different from that in the first embodiment in that: an antibacterial microcapsule coating 4 is provided on the surface of the second wood pulp spunlace nonwoven fabric layer 23 close to the second wear-resistant spunlace nonwoven fabric layer 3. This can improve the antibacterial effect of the spunlace nonwoven fabric.

[0028] Furthermore, the antibacterial microcapsules used in the antibacterial microcapsule coating 4 include a core material and a wall material, the wall material is β-cyclodextrin, and the core material is Forsythia suspensa oil.

[0029] Another difference from the embodiment is that the first wear-resistant spunlace nonwoven fabric layer 1 is compounded with an oil-absorbing fiber layer 5 on one side close to the first wood pulp spunlace nonwoven fabric layer 21. The fiber used in the oil-absorbing fiber layer 5 is PVDF porous nanofiber or kiwano fiber. In this embodiment, PVDF porous nanofiber is selected.
