Description

Technical Field

[0001] The present invention relates to the technical field of all-cotton wet wipe production, and particularly relates to a mild and non-irritating all-cotton wet wipe for neonatal care and its production process. Background Art

[0002] Wet wipes are commonly used cleaning products for neonatal care. The wet wipes for neonatal care are mainly all-cotton wet wipes. The all-cotton wet wipes use all-cotton non-woven fabric as the base cloth, and are required to have no adverse stimulation or allergic reaction to the human body, and usually do not contain other fibers.

[0003] Compared with adults, the skin of newborns is more delicate, and it is usually required that the wet wipes do not contain any additives. In addition, although the cotton fibers used in all-cotton non-woven fabric are soft and comfortable, the surface of the all-cotton non-woven fabric after hydrospinning is relatively hard and cannot provide the same touch as the sueded fabric. Adults may not feel uncomfortable when using it, but it still has irritation to the skin of newborns and is not friendly enough, so improvement is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a mild and non-irritating all-cotton wet wipe for neonatal care and its production process, so as to improve the nursing effect and use comfort, and reduce the irritation to the skin during neonatal care.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A production process of an all-cotton wet wipe includes the following steps:

[0007] a. Fiber web formation: Natural pure cotton is used for opening, carding and impurity removal, and a cotton web is obtained after laying the web.

[0008] b. Lamination: The first screen is placed on the second screen. One or more layers of cotton webs are taken as the first non-woven fabric semi-finished product and placed on the top surface of the first screen, and one or more layers of cotton webs are taken as the second non-woven fabric semi-finished product and placed on the bottom surface of the second screen to form a composite mesh belt.

[0009] c. Hydrospinning: The composite mesh belt is pulled, pre-wetted and then subjected to hydrospinning to obtain a first non-woven fabric above the first screen and a second non-woven fabric below the first screen, and there are fiber bundles passing through the first screen and the second screen between the first non-woven fabric and the second non-woven fabric, and then dehydration is carried out.

[0010] d. Separation: Individually traction the first wire mesh around the first guide roller and the second wire mesh around the second guide roller, so that the first wire mesh is separated from the second wire mesh. Then use a blade to cut the fiber bundle at the separation of the first wire mesh and the second wire mesh, splitting the fiber bundle into two, obtaining the first fiber bundle and the second fiber bundle. Individually traction the first non-woven fabric around the third guide roller to obtain the first non-woven fabric with a layer of the first fiber bundle on the bottom surface, and individually traction the second non-woven fabric around the fourth guide roller to obtain the second non-woven fabric with a layer of the second fiber bundle on the top surface;

[0011] e. Sterilization: Wind up the first non-woven fabric and the second non-woven fabric and perform high-temperature degreasing treatment, then carry out steam sterilization, and then dry;

[0012] f. Cutting: Take the first non-woven fabric or the second non-woven fabric for cutting as the base cloth of the wet wipe. After stacking the base cloths, place them into the packaging, and add pure water to obtain the all-cotton wet wipe.

[0013] Wherein, the length of the first fiber bundle corresponds to the thickness of the first wire mesh.

[0014] Wherein, the length of the second fiber bundle corresponds to the thickness of the second wire mesh.

[0015] Wherein, the first fiber bundle and the second fiber bundle have the same length.

[0016] Wherein, the blade is driven by a reciprocating drive mechanism, so that the blade reciprocates along the width direction of the first wire mesh.

[0017] Wherein, the reciprocating drive mechanism includes a motor, a turntable, a guide rod and a connecting rod. The guide rod is horizontally arranged in front of the blade, and linear bearings connected to the blade are spaced on the guide rod. The motor is vertically arranged in front of the guide rod, the turntable is horizontally arranged on the rotating shaft of the motor, a pin shaft is eccentrically arranged on the turntable, and the connecting rod is arranged between the pin shaft and a linear bearing.

[0018] Wherein, the first wire mesh and the second wire mesh are densely covered with mesh holes.

[0019] Wherein, the first wire mesh and the second wire mesh are made of stainless steel wire mesh.

[0020] To achieve this purpose, the present invention adopts the following another technical solution:

[0021] A mild and non-irritating all-cotton wet wipe for neonatal care is prepared by using the above all-cotton wet wipe production process.

[0022] Advantages of the present invention: A mild and non-irritating all-cotton wet wipe for neonatal care and its production process provide the touch of a napped fabric through soft fiber bundles, making the body feel more comfortable, enhancing water absorption, reducing skin irritation during neonatal care, and using fiber bundles to improve the cleaning and care effect. Moreover, it contains no additives to ensure mildness and no irritation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 is a schematic structural diagram of the present invention;

[0024] Figure 2 is Figure 1 a top view of the middle blade. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following combines Figures 1 to 2 and further illustrates the technical solutions of the present invention through specific embodiments.

[0026] A production process of an all-cotton wet wipe includes the following steps:

[0027] a. Fiber web formation: Pure natural raw cotton is used for opening, carding, and impurity removal. After laying the web, a cotton web is obtained, which contains no other fibers. The pure natural raw cotton material has no allergenicity;

[0028] The traditional non-woven fabric production process is to degrease, bleach, and then hydroentangle. In this application, the pure natural raw cotton fibers are not degreased before web formation, reducing the fiber damage during carding, ensuring the strength of the fibers, and reducing the risk of fiber shedding during the use of the wet wipe;

[0029] b. Lamination: Place the first screen 3 on the second screen 4. Take one or more layers of cotton web as the first non-woven fabric semi-finished product and place it on the top surface of the first screen 3. Take another one or more layers of cotton web as the second non-woven fabric semi-finished product and place it on the bottom surface of the second screen 4 to form a composite mesh belt; In this embodiment, the first screen 3 and the second screen 4 are densely covered with mesh holes, which does not affect the subsequent hydroentangling process;

[0030] c. Hydroentangling: The composite mesh belt is pulled, pre-wetted, and then hydroentangled to obtain the first non-woven fabric 1 above the first screen 3 and the second non-woven fabric 2 below the first screen 3. And there are fiber bundles passing through the first screen 3 and the second screen 4 between the first non-woven fabric 1 and the second non-woven fabric 2, and then dehydrated;

[0031] During the hydroentangling process, high-pressure micro water jets are sprayed onto the first non-woven fabric semi-finished product and the second non-woven fabric semi-finished product to promote the mutual entanglement between the fibers and improve the structural stability;

[0032] In addition, the first wire mesh curtain 3 and the second wire mesh curtain 4 are made of stainless steel wire mesh, which has good anti-water flow impact effect, is durable, and the stainless steel wire mesh can be wound and unwound synchronously, making it convenient to use;

[0033] d. Separation, as Figure 1 shown, the first wire mesh curtain 3 is separately pulled around the first guide roller 7, and the second wire mesh curtain 4 is separately pulled around the second guide roller 8, so that the first wire mesh curtain 3 and the second wire mesh curtain 4 are separated, and the fiber bundle is cut from the separation of the first wire mesh curtain 3 and the second wire mesh curtain 4 by using the blade 9, dividing the fiber bundle into two, obtaining the first fiber bundle 11 and the second fiber bundle 12, which is convenient for processing. The length of the first fiber bundle 11 corresponds to the thickness of the first wire mesh curtain 3, and the length of the second fiber bundle 12 corresponds to the thickness of the second wire mesh curtain 4;

[0034] In this embodiment, the blade 9 cuts from the middle of the fiber bundle, so that the first fiber bundle 11 and the second fiber bundle 12 have the same length, and the length is 1 - 2 mm at the same time, with good uniformity;

[0035] The touch of the sanding fabric is provided by the first fiber bundle 11 and the second fiber bundle 12, making the body feel more comfortable during the use of the wet wipes, improving the water absorption, and reducing the irritation to the skin during the neonatal care process;

[0036] Figure 2 shown, the blade 9 is driven by a reciprocating drive mechanism, so that the blade 9 reciprocates along the width direction of the first wire mesh curtain 3 to achieve efficient cutting of the fiber bundle; In this embodiment, the reciprocating drive mechanism includes a motor 16, a turntable 14, a guide rod 17 and a connecting rod 13. The guide rod 17 is horizontally arranged on the front side of the blade 9, and the blade 9 is fixed by a bracket.

[0037] Linear bearings 10 connected to the blade 9 are arranged at intervals on the guide rod 17. The blade 9 and the linear bearings 10 can be fixed by bolts, and the blade 9 is guided by the linear bearings 10 to ensure that the blade 9 moves along the straight line direction of the guide rod 17;

[0038] The motor 16 is vertically arranged on the front side of the guide rod 17, the turntable 14 is horizontally arranged on the rotating shaft of the motor 16 and rotates with the motor 16. A pin shaft 15 is eccentrically arranged on the turntable 14, and the connecting rod 13 is arranged between the pin shaft 15 and a linear bearing 10. The pin shaft 15 rotates eccentrically with the turntable 14 to drive the linear bearing 10 to move on the guide rod 17, driving the reciprocating movement of the blade 9;

[0039] As Figure 1As shown, the first non-woven fabric 1 is separately pulled around the third guide roller 5 to obtain the first non-woven fabric 1 with a layer of first fiber bundles 11 on the bottom surface, and the second non-woven fabric 2 is separately pulled around the fourth guide roller 6 to obtain the second non-woven fabric 2 with a layer of second fiber bundles 12 on the top surface; since the lengths of the first fiber bundles 11 and the second fiber bundles 12 are the same, the first non-woven fabric 1 and the second non-woven fabric 2 can be interchanged, that is to say, two non-woven fabrics can be produced at one time, with high efficiency;

[0040] e. Sterilization. The first non-woven fabric 1 and the second non-woven fabric 2 are wound up and subjected to high-temperature degreasing treatment, then steam sterilization is carried out, and then drying; in this embodiment, degreasing treatment can be carried out by high-temperature cooking to improve the sterilization effect;

[0041] f. Cutting. Take the first non-woven fabric or the second non-woven fabric for cutting as the base cloth of the wet wipe. After the base cloths are stacked, they are placed into a packaging container, and pure water is added to obtain a pure cotton wet wipe without additives, ensuring that the pure cotton wet wipe is non-toxic, non-irritating and non-allergenic.

[0042] A mild and non-irritating pure cotton wet wipe for neonatal care is prepared by the above pure cotton wet wipe production process, with a more soft and comfortable touch, mild and non-irritating, and suitable for neonatal care.

[0043] The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
