Abstract

PROBLEM TO BE SOLVED: To continuously provide cotton masses depressed in the fuzzing of their surfaces and holding sufficient absorbing capacities at a low cost in mass production. SOLUTION: The surface of a silver-like absorbent cotton 1 is subjected to a fuzzing-inhibiting treatment and subsequently cut in a prescribed length to form the cotton masses 10. Therein, the fuzzing-inhibiting treatment is performed by charging the silver-like absorbent cotton 1 into a fuzzing-inhibiting treatment means 2 comprising upper and lower wide circulated belt-like crumpling members 3 vertically disposed at a prescribed distance and repeatedly moved in lateral directions opposite to each other so as to be orthogonal to the charging direction. Each of the cotton mass 10 has an approximately elliptical or oval shape on the cross section approximately orthogonal to the longitudinal direction which is the fiber direction of the silver-like absorbent cotton 1. The cotton mass may have columnar shape whose cut cross section is approximately circular. Further, both the near-end places of the cotton mass in the direction of the fibers may strongly be pressed to form press-collapsed parts at both the end parts.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cotton lump obtained by cutting a roll-shaped cotton used as a cotton ball substitute mainly used in the medical field, as a packing material for padding, a filter for various cleaning equipment, and the like. It relates to a manufacturing method.

[0002]

2. Description of the Related Art Conventionally, the diameter is, for example, approximately 5 to 15 mm.
The various sizes of the cotton balls are mainly used in the medical field for absorbing body fluid in the affected area, holding the affected area, and the like. In the manufacture of such cotton balls, conventionally, degreased cotton is made into a sliver (sinko cotton) using a carding machine and then cut, and the slipped or degreased cotton is unwound and rounded into a small spherical shape, or crossed with each other. After intermittently winding and winding cotton with a fork or needle,
Each needle was molded by pulling out a needle or the like.

[0003]

However, since the conventional spherical forming process for each piece is intermittent, the manufacturing cost is high and the production efficiency is poor. That is, in consideration of the purpose of using the cotton ball, fluffing on the surface is suppressed, and a sufficient absorption amount of body fluid and other liquids is retained, and it is an inexpensive one that is easily used. However, the conventional manufacturing method has not sufficiently satisfied such a demand.

Therefore, the present inventor has earnestly studied a method for producing a sphere-like shape in a large amount at a low cost by suppressing the fluffing of the absorbent cotton as a material, and as a result of the sliver-shaped absorbent cotton. It was found that the fluff on the surface can be suppressed by continuously rubbing it, and that a cotton lump similar to a cotton ball can be obtained by cutting it to an appropriate length, and the present invention was created. .
That is, the present invention is that the fluff on the surface is suppressed, and that a sufficient amount of liquid or the like is absorbed, and is suitable for continuous mass production. And its manufacturing method.

[0005]

In order to achieve the above-mentioned object, in a cotton lump formed by cutting a roll-shaped cotton according to the present invention, a sliver-shaped absorbent cotton 1 having a surface subjected to a fluff suppressing treatment has a predetermined length. It is characterized by being cut into pieces and formed into lumps. The shape is such that the cross section substantially orthogonal to the length direction which is the fiber direction of the sliver-shaped absorbent cotton 1 exhibits a substantially oval shape or an elliptical shape, and the cross section has a substantially circular shape and a substantially columnar shape. Similarly, by strongly pressing the vicinity of both ends along the fiber direction, it is possible to form the crushed portions 11 at both ends, respectively.

Further, the manufacturing method is characterized in that after the surface of the sliver-like absorbent cotton 1 is subjected to the fluff suppressing treatment, it is cut into a predetermined length to form the cotton lump 10.
The fluff suppressing process at this time is a circulating belt-like upper and lower buff member which are arranged at a predetermined interval in the vertical direction and whose amplitudes are repeated in mutually opposite directions so as to be substantially orthogonal to the feeding direction. The sliver-like absorbent cotton 1 can be fed into the fluff suppressing treatment means 2 composed of 3.

In the cotton mass obtained by cutting the rolled cotton according to the present invention having the above-mentioned structure, and the method for producing the same,
The fluff suppressing treatment performed on the surface of the sliver-shaped absorbent cotton 1 suppresses fluffing on the surface of the cut and formed cotton lump 10 and prevents, for example, the cotton on the surface from peeling off and adhering to the affected area. The fluff suppressing treatment for the sliver-like absorbent cotton 1 suppresses fluff formation on the surface of the formed cotton lump 10, and the fluff suppressing treatment means 2 changes the amplitude of the upper and lower buff members 3 in a direction substantially orthogonal to the feeding direction. , The surface of the sliver-shaped absorbent cotton 1 is prepared and molded into a predetermined size. The sliver-shaped absorbent cotton 1 is continuously fed into the fluff suppressing treatment means 2, and the sliver-like absorbent cotton 1 after the fluff suppressing treatment is cut at a predetermined length to continuously produce a large amount of cotton lumps 10.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, referring to the drawings, an embodiment of the present invention will be described. Reference numeral 10 shown in the drawings is a cotton lump formed by cutting a roll-shaped cotton according to the present invention. No. 10 is obtained by subjecting sliver-shaped absorbent cotton (cinnamon cotton) to fluff suppressing treatment and then cutting it into a predetermined length.

That is, first, the scoured and bleached absorbent cotton is removed by a carding machine to remove impurities, short fibers, etc., and at the same time, the entangled cotton fiber masses are stretched to be parallel to each other while being stretched to be in a parallel state. A sliver-shaped absorbent cotton 1 in the form of a string of about 5 to 15 mm is formed. Next, the sliver-like absorbent cotton 1 is fed into the fluff suppressing treatment means 2 as shown in FIG. 1, and the fluff suppressing treatment means 2 has a predetermined interval at the upper and lower sides, for example, the diameter of the formed sliver-like absorbent cotton 1. The upper and lower buff members 3 are in the form of a wide belt that circulates and is distant from each other at corresponding intervals, and oscillates in opposite directions to each other with a narrow amplitude. The feeding of the sliver-shaped absorbent cotton 1 to the fluff suppressing treatment means 2 is not limited to one as shown in the figure, but may be performed by a plurality of fibers with an appropriate interval set so as not to get entangled with each other. . After the fluff suppressing treatment by the fluff suppressing processing means 2, the cutter means 4 has a predetermined length, for example, 10 to 30 mm.
Cotton lumps cut into rolls and cut to length 1
You get 0. The cutter means 4 in the illustrated example has, for example, a blade edge inclined and vertically moves at least one of a pair of cutting blades arranged vertically so as to rub the blade edge with respect to the other, and is a so-called guillotine cutter. It is called. Needless to say, the cutting blade structure is not limited to the illustrated example, and a rotary round blade, a flat blade, or the like can be selected. The point is that the continuous sliver-shaped absorbent cotton 1 sent from the fluff suppressing processing means 2 is predetermined. It is sufficient if the length is automatically cut.

The shape of the cut and formed cotton lump 10 is shown in FIG.
As shown in (A), the sliver-like absorbent cotton 1 is half crushed by the cutter means 4 of the guillotine cutter, so that the cross section substantially orthogonal to the length direction, which is the fiber direction of the sliver-like absorbent cotton 1, is substantially oval. Or, it can be molded to have an elliptical shape. According to this, since the overall shape is similar to a spherical shape, it is suitable as a substitute for a conventional cotton ball, and there is an advantage that the peeling of the cotton fiber is small because the ends are sealed.

Further, as shown in FIG. 2 (B), the shape shown in FIG. 2 (A) is restored to the original shape of the cut surface after cutting,
Alternatively, it can be molded into a columnar shape having a substantially circular cross section by cutting with a rotary round blade. According to this, not only is the edge portion soft and the irritation to the wound of the affected area is reduced, but also the water absorption amount is increased due to the large volume.

Further, as shown in FIG. 2C, a flat crushed portion 11 is formed at both ends by strongly pressing the vicinity of both ends after cutting and forming into the shape shown in FIG. 2B. You can also do it. According to this, the edges are soft, the irritation to the wound of the affected area is small, and the cotton fibers on the surface are difficult to peel off.

A cotton lump 10 formed by the method of the present invention.
Is obtained by subjecting the sliver-like absorbent cotton 1 to fluff suppressing treatment by the fluff suppressing treatment means 2 and then cutting (cutting) continuous long roll absorbent cotton, so to speak Therefore, its use is no different from conventional cotton balls.
That is, for example, it can be used for absorption and removal of body fluid and the like in the affected area for medical use, can be used for pressing the affected area, etc. Moreover, its softness can be used as a packing material for stuffing, and by utilizing its adsorptivity, etc. as a filter for various cleaning equipment. Further, it is used for various purposes.

Here, a conventional cotton ball and a cotton lump 1 according to the present invention 1
The results of the water absorption test with 0 were as follows. That is, a conventional cotton ball (60 balls in total) adjusted to have a total weight of 5 g has a water absorption amount of 64 g, whereas the present invention similarly adjusts the total weight to 5 g. The water absorption of the cotton lump 10 (the number of which was 93) was 102 g. This is due to the fact that the cotton lump 10 according to the present invention retains its shape in a softer state, that is, in a softer state than the conventional cotton balls, and thus the water absorption increases. It seems.

[0015]

The present invention is configured as described above.
For this reason, the cotton lump 10 according to the present invention suppresses the fluffing of the surface, and further retains a sufficient absorption amount of liquid etc. Further, the production of the cotton lump by cutting the rolled cotton according to the method of the present invention. The method is suitable for continuous mass production of cotton lumps 10 and enables inexpensive provision.

That is, this is because, in the cotton lump 10 according to the present invention, the sliver-like absorbent cotton 1 having the surface subjected to the fluff suppressing treatment is cut into a predetermined length to form a lump. This is because, in the manufacturing method, the surface of the sliver-shaped absorbent cotton 1 is subjected to the fluff suppressing treatment, and then cut into a predetermined length to form the cotton lump 10.

In particular, since the surface of the sliver-shaped absorbent cotton 1 is subjected to a fluff suppressing treatment, fluff on the surface of the cut cotton lump 10 is suppressed, and when used for medical purposes, the cotton on the surface peels off and adheres to the affected area. It is possible to prevent this from happening and to be hygienically usable.

When the sliver-shaped absorbent cotton 1 is fed to the fluff suppressing treatment means 2 for performing the fluff suppressing treatment, the amplitude of the upper and lower buff members 3 in a direction substantially orthogonal to the feeding direction is sliver-like. The surface of the absorbent cotton 1 is conditioned and molded into a predetermined size, and furthermore, it can be continuously processed by feeding and the work can be performed extremely efficiently. Furthermore, a large amount of cotton lumps 10 can be produced from the sliver-shaped absorbent cotton 1 that is continuously delivered by cutting the sliver-like absorbent cotton 1 after the fluffing suppression treatment by a predetermined length by the cutter means 4, and it is possible to provide at low cost. It is something to do.
