Problems solved by technology

However, wood pulp fibers are natural short fibers, which only have hygroscopicity and poor water retention. After absorbing water, water is easy to re-separate under a certain external force. The surface humidity of the object to be cleaned is too high, with residual water stains, but the cleaning is not clean

Embodiment 1

[0070] Such as figure 1 Shown, the present invention discloses a kind of manufacturing method of absorbent wipes, comprises the following steps:

[0071] (1) The wood pulp 11 is loosened by the opening roller A1, mixed with the superabsorbent resin 12, and then passed through the nozzle B1 under the action of the auxiliary airflow to form a wood pulp fiber web 13 containing the superabsorbent resin 12.

[0072](2) Using the melt-blowing process, heat and melt the thermoplastic resin, and use high-temperature, high-speed hot air to blow the melted stream of thermoplastic resin sprayed from the spinnerets C1 and C1' into fibers with a fiber diameter of ≤10 μm bundles, thereby forming melt-blown fiber webs 14, 15 along with the hot air flow, and intersecting with the two sides of the wood pulp fiber web 13 to form melt-blown fiber webs 14, 15 on both sides, and a superabsorbent resin 12 in the middle. The multi-layer structure fiber web 16 of the wood pulp fiber web 13, wherein,...

Embodiment 2

[0077] Such as image 3 As shown, the present invention discloses a water-absorbent wipe, which has a layered structure. The upper and lower layers of the water-absorbent wipe 27 are melt-blown fiber webs 24, 25, and the middle layer is a fabric containing a superabsorbent resin 22. Wood pulp fiber web 23, described wood pulp fiber web 23 also contains wood pulp 21, wherein, the melt-blown fiber of described melt-blown fiber web 24,25 intersperses in wood pulp fiber web 13; Said melt-blown fiber web 24 , 25 may contain melt-blown fibers 20 whose fiber surfaces are high-melting-point resins, melt-blown fibers 20' whose fiber surfaces contain low-melting-point resins, or blended fibers of the two, and the difference between the melting points of the high-melting-point resins and low-melting-point resins is ≥ 20 ℃. The melt-blown fiber 20' containing low-melting resin on the surface of the fiber can be a single-component melt-blown fiber, a two-component melt-blown fiber or a mi...

Embodiment 3

[0080] Such as Figure 5 Shown, the present invention discloses a kind of manufacturing method of absorbent wipes, comprises the following steps:

[0081] (1) The wood pulp 41 is loosened by the opening roller A4, mixed with the superabsorbent resin 42, and then passed through the nozzle B4 under the action of the auxiliary airflow to form a wood pulp fiber web 43 containing the superabsorbent resin 42.

[0082] (2) The thermoplastic resin and the hydrophilic masterbatch 40, 40' are heated and melted by using the melt-blown process, and the thermoplastic resin and the hydrophilic masterbatch 40, 40' sprayed from the spinneret C4, C4' are sprayed by high temperature and high-speed hot air flow The melt fine flow of 'is blown into fiber bundles with a fiber diameter of ≤10 μm, thereby forming hydrophilic melt-blown fiber webs 44, 45 with the hot air flow, and with the two sides of the wood pulp fiber web 43 containing superabsorbent resin 42 The place intersects to form a hydro...

Abstract

The invention discloses a water-absorbing wipe. The upper and lower layers of the water-absorbing wipe are provided with melt-blown fiber nets; the intermediate layer of the water-absorbing wipe is provided with a wood pulp cellulose net with a super absorbent resin; and melt-blown fibers of the melt-blown fiber nets are inserted into the wood pulp cellulose net. The invention further discloses amanufacturing method of the water-absorbing wipe. The method can be used for manufacturing the water-absorbing wipe disclosed by the invention. When the water-absorbing wipe is matched with water or acleaning agent, the super absorbent resin is capable of rapidly absorbing water or the cleaning agent. During wiping, by virtue of the liquid retention ability of the super absorbent resin, the wateror the cleaning agent is slowly released onto the surface of the cleaned object, and stains can be rapidly removed under the condition that the wipe is wetted. Moreover, after lots of water or cleaning agents can be absorbed by the wipe, the surface is dry and comfortable, any liquid drip phenomenon is avoided, and the wipe is convenient to use under the wetting condition.

Description

technical field [0001] The invention relates to the technical field of wipes, in particular to a water-absorbing wipe used in personal care and infant care and a manufacturing method thereof. Background technique [0002] Wipes are often used in daily life, for example, when parents change diapers for babies, or when eating in restaurants, or when making up and caring for the skin. Because wipes are quite convenient to carry and store, and are easy to use, they are widely used. Consumer favorite. Therefore, wipes are more and more widely used in personal care and infant care. [0003] The wipes can be used wet or dry, not only for wiping dust and stains, but also for removing stubborn stains with water or detergent. In order to enhance the moisture absorption and water absorption performance of the wipes, wood pulp is often added to the wipes to improve the moisture absorption and decontamination capabilities of the wipes. However, wood pulp fibers are natural short fiber...
