Background

The dietary structure of Chinese people is different from that of western people, and the dietary types and cooking tools are greatly different from those of western countries. In the Chinese diet processing, the Chinese food is fried, cooked and fried in a large proportion, so that the Chinese kitchen has large oil fume, and the wall surface of the kitchen is easy to become greasy and is not easy to clean. It is common practice to spray a cleaning agent on the wall surface and then wipe it with a kitchen rag. Because the oil stain in the kitchen is difficult to clean, the oil stain is difficult to clean at one time by using the conventional non-woven fabric for wiping. Typically, a relatively coarse wiping material is used to clean relatively large dirt. And then wiping the residual oil stains by adopting a relatively fine wiping material. This method requires replacement between the two wipes, which is cumbersome.

Detailed Description

The utility model is further described with reference to the following figures and specific examples.

Example one

This embodiment will be described in detail with reference to fig. 1. The composite nonwoven fabric for double-sided wiping according to the present embodiment includes a first wiping surface layer 1, a separator 3, and a second wiping surface layer 2 which are combined with each other; the release film 3 is used for moisture transport between the first wipe face layer 1 and the second wipe face layer 2.

The first wiping face layer 1 comprises dust-free paper 11 and a bi-component fiber layer 12 subjected to thermal bonding; the bicomponent fiber layer 12 is made of sheath-core bicomponent fibers through an air-laid mode, the fineness of the sheath-core bicomponent fibers is 10-20D, the length of the sheath-core bicomponent fibers is 10-15mm, and the specific selection is 15D. The fineness of the used sheath-core bicomponent fiber is 10-20D, and the used sheath-core bicomponent fiber is thicker than the diameter of the conventional non-woven fabric fiber, and can wipe some intractable oil stains. The sheath-core bicomponent fiber is one of PE/PP, PE/PET, terylene bicomponent fiber or PLA bicomponent fiber. In this example, PE/PET was chosen, i.e. the skin layer was low melting PE and the core layer was conventional PET. One side of the dust-free paper 1 is adjacent to the separation film 3.

The dust-free paper 11 and the bicomponent fiber layer 12 are bonded and fixed in a thermal bonding mode, and the bicomponent fiber layer is a fiber layer which is made of sheath-core bicomponent fibers in an air-laid mode.

The dust-free paper is prepared by a thermal bonding method, and low-melting-point fibers are added into the dust-free paper during production. The thermal bonding method is to mix the hot melt fiber into the fluff pulp fiber, the mixing ratio is generally not less than 15%, after the air-laid, the low-melting fiber in the fiber web is melted by hot air or hot rolling, and the fiber web is reinforced into cloth. The non-woven fabric of the thermal bonding method does not contain chemical adhesive, so that the bulkiness and the moisture absorption of the product are better.

The weight of the dust-free paper used in the present invention in square meters is 20 to 60 g, and the weight of the dust-free paper used in the present example in square meters is 30 g; the distilled water absorption rate of the dust-free paper used in the present invention was 21 to 50, and the distilled water absorption resolution of the dust-free paper used in this example was 30; the multiplying power of the dust-free paper used in the utility model for absorbing the physiological saline is 11-20, and the multiplying power of the dust-free paper used in the embodiment for absorbing the physiological saline is 15; the tensile strength of the dust-free paper used in the present invention was 0.2 to 0.6KN/m, and the tensile strength of the dust-free paper used in this example was 0.4 KN/m.

In the embodiment, the dustless paper and the sheath-core bicomponent fiber are compounded on line, and the sheath layer with the low melting point and the low melting point fiber contained in the dustless paper can be melted through a hot air or hot rolling mode, so that the low melting point fiber layer and the dustless paper can be well bonded together.

The second wiping surface layer 2 is made of superfine fiber spunlace non-woven fabric. The superfine fiber used in the superfine fiber spunlace non-woven fabric is sea-island superfine fiber, wherein the sea-island component ratio is 30: 70 or 20: 80, the sea component is COPET or PVA, and the island component is PA6 or PET.

Further, the separator 3 used in this example is a microporous membrane. The microporous membrane is one of PTFE, PU, TPU or PLA microporous membranes. In this example, a microporous PLA membrane was chosen. The microporous membrane 3 has waterproof and breathable effects, and can prevent moisture from permeating between the first wiping face layer 1 and the second wiping face layer 2, i.e., when the first wiping face layer 1 is used, the second wiping face layer 2 is not affected.

Example two

This embodiment will be described in detail with reference to fig. 2. The present embodiment is different from the first embodiment in that: an oil absorption layer 4 is arranged on the surface of the first wiping surface layer, and the nano oil absorption fiber is applied to the upper surface of the first wiping surface layer in an electrostatic spinning mode. The thickness of the oil absorption layer 4 is only 0.1mm, and the first wiping surface layer is thick in fiber and rough in surface, so that the wiping of the first wiping surface layer on intractable oil stains is not affected. The diameter of the formed nano-fiber is 200-600nm, and the oil absorption rate is 35-44 g/g. Can perform good adsorption effect on oil stains in a kitchen.
