Problems solved by technology

However, compared with woven fabrics, non-woven fabrics also have the following disadvantages: poorer strength and durability, poor hydrophilicity
[0003] In the prior art, the Chinese invention patent with the application number 201510475857.3 discloses a degradable non-woven fabric impregnated compound preparation process and its materials. The production process is to immerse at least one side of the PVA non-woven fabric in the PVA colloidal solution , and by controlling the mass fraction of PVA in the colloidal solution to be 10%-30%, the number of the dipped surface of the non-woven fabric is controlled to be different, and then the PVA non-woven fabric dipped surface and the PVA non-woven fabric are rolled and dried , cooling operations and compounding steps, however, the glue used in this invention acts as a barrier to liquids and solids, and has the disadvantages of poor hydrophilicity and inability to clean, and it is easy to crack from a right angle direction

Embodiment 1

[0058] The present invention utilizes the dipping device of above-mentioned honeycomb amphiphilic non-woven fabric to carry out the technology of dipping, comprises the following steps:

[0059] 1) Place the non-woven fabric (the non-woven fabric of the present invention is a needle-punched felt non-woven fabric blended with nylon and polypropylene) on the first cloth roll retracting frame 1, and pass it through the first press roller 2, The first main roll 3 and the first guide roll 4 enter the first dipping tank 6 under the drafting of the first support roller 5 and dip in the first dipping bath with a temperature of 20°C to soak the nonwoven fabric. The surface of the cloth, so that the surface of the non-woven fabric is attached with a layer of surfactant, after dipping, the excess first bath dipping on the non-woven fabric is scraped back to the first dipping tank 6 by the first scraper 7;

[0060] 2) The non-woven fabric treated in step 1) passes through the second press...

Embodiment 2

[0083] Embodiment 2: The dipping process of honeycomb amphiphilic nonwoven fabric of the present invention is except following difference, all the other are with embodiment 1:

[0084] The first bath dipping consists of the following components in parts by weight: 490 parts of water, 10 parts of surfactants, wherein the surfactants are oleic acid, lauric acid, sodium laurate sulfate in a mass ratio of 1:2 : 3 mixed;

[0085] The deployment method of the first bath dipping is as follows:

[0086] (1) Add water into the reaction tank first, and control the water temperature at 30°C;

[0087] (2) Put the surfactant sodium lauryl sulfate into the reaction tank, stir for 25 minutes and mix well.

[0088]The second bath dipping glue consists of the following components in parts by weight: 600 parts of PVA glue, 150 parts of water, adhesive (adhesive is epoxy water-based adhesive, phenolic water-based adhesive, organic silicon water-based adhesive) Adhesive, rubber water-based adh...

Embodiment 3

[0104] Embodiment 3: The dipping process of honeycomb amphiphilic nonwoven fabric of the present invention is except following difference, all the other are with embodiment 1:

[0105] The first bath dipping consists of the following components in parts by weight: 470 parts of water, 30 parts of surfactants, wherein the surfactants are sodium dodecylsulfonate, sodium stearate, oleic acid, Lauric acid is mixed according to the mass ratio of 1:2:3:4;

[0106] The deployment method of the first bath dipping is as follows:

[0107] (1) Add water into the reaction tank first, and control the water temperature at 25°C;

[0108] (2) Put the surfactant sodium lauryl sulfate into the reaction tank, stir for 20 minutes and mix well.

[0109] The second bath dipping consists of the following components in parts by weight: 500 parts of PVA glue, 100 parts of water, adhesive (adhesive is water-based polyurethane adhesive, ethylene acetate water-based adhesive, ring Oxygen water-based ad...

Abstract

The invention discloses a glue-dipping apparatus for honeycomb-shaped amphiphilic non-woven fabrics and a process therefor. The glue-dipping apparatus includes a first fabric roll retracting / releasingframe and a second fabric roll retracting / releasing frame, and also includes a first glue-dipping bath device, a second glue-dipping bath device, a third glue-dipping bath device, and a drying device, which are arranged successively between the first fabric roll retracting / releasing frame and the second fabric roll retracting / releasing frame. In a glue-dipping process, CO2 gas is generated through reactions in first glue-dipping bath and second glue-dipping bath, and during release of the CO2, micropores are formed, so that a prepared non-woven fabric has a rough outer surface and has honeycomb-like or algae-like natural appearance entirely, thus increasing contact area and further greatly improving water and oil absorption capability. The prepared non-woven fabric has better cleaning effect.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a dipping device for honeycomb amphiphilic non-woven fabrics and a process thereof. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. Non-woven fabric is a new type of fiber product with soft, breathable and planar structure, light weight, breathable, non-toxic, convenient and practical. However, compared with woven fabrics, non-woven fabrics also have the following disadvantages: poorer strength and durability, and poor hydrophilicity. [0003] In the prior art, the Chinese invention patent with the application number 201510475857.3 discloses a degradable non-woven fabric impregnated compound prep...
