Description

  The present invention relates to a cleaning tool for cleaning a floor surface and a wall surface, and more particularly, to a pile fiber thread, a wiping body, and a cleaning tool having a high ability to collect pet hair, human hair, fiber waste, and the like. .

  Conventionally, a cleaning mop has been widely used as a cleaning tool for homes and workplaces. Such a cleaning mop is suitable for removing dust such as house dust, i.e., fibrous dust such as sand dust, human hair and pet hair, components derived from mites, and food waste, etc. The demand is increasing in stores and homes. In particular, a type of cleaning mop in which the mop can be removed from the mop gripping part is often used. This cleaning mop is composed of a mop that directly contacts the floor surface or the like and a holder, and the holder is composed of a mop gripping part on which the mop is mounted and a handle gripped by a person. The tip of the handle is connected to the mop gripping part through a joint, and the mop is rotatably held and can be easily attached and detached.

  This mop has a shape such as an ellipse or a rectangle, and is constructed by planting a large number of piles on the entire bottom surface of the mop base fabric. In some cases, they are bound together. These piles are formed by twisting a plurality of single yarns and sewing them to an appropriate length. Conventionally, cotton fibers have been used for the pile and mop base fabrics. Mops using cotton fibers are widely used because of their low cost and good cleanability after use. However, cotton fibers are highly water-absorbent and require more time to dry. There was a problem that a lot of litter occurred. Further, due to many washings, the hydrophilic OH group possessed by the cotton fiber is lost and contracted, and the elasticity is lowered, so that the collection property of house dust is deteriorated.

  Therefore, at present, synthetic fiber is often used for mops. Chemical fiber includes filament yarn (continuous yarn made of long fibers) and span yarn (twisted yarn made of short fibers). Filament yarns are advantageous in that they are lightweight and have a short drying time after washing. On the other hand, the spun yarn has the advantage that the outer peripheral surface of the yarn has irregularities, so that the house dust is easily collected.

  Under such technical background, the present applicant has disclosed a technique for forming a mop by sewing a pile on a mop base fabric, and a technique for mounting the mop on a gripping part. It was announced as (Patent Document 1).

  FIG. 6 is a schematic explanatory view of a conventional cleaning mop. The cleaning tool 110 is configured by attaching a mop 102 to a mop holder 111. The mop holder 111 is configured by rotatably connecting the handle 112 via a joint 115 formed on the grip portion 114. The mop 102 is configured by planting a large number of piles 108 on the lower surface of the base fabric 104 (hidden under the gripping portion 114 in FIG. 6). Is formed. The left and right end portions of the grip portion 114 are inserted into the bag-like portions 107 and 107, and the mop 102 is attached to the mop holder 111, whereby the cleaning tool 110 is completed. FIG. 7 is a view showing the formation of a conventional pile short fiber used in the pile. Short fibers 150 of 3d (denier) or less are twisted to form a single yarn 152 of 4S (British count) to 15S (7A, 7B), and a plurality of single yarns 52 are twisted to form an original yarn 154 (7C). Two raw yarns 154 are twisted to form a pile fiber yarn 156 (7D), and this pile fiber yarn 156 is used as the pile 108.

JP 2005-270630 A

  The mop 102 in Patent Document 1 has good dust removal properties, but it has been found that there is sufficient room for improving cleaning properties. In particular, in order to sufficiently remove house dust such as dust during the cleaning operation, it is necessary to wipe the cleaning surface a plurality of times, and the cleaning efficiency is never high. Moreover, since 4S-15S single yarn is formed by twisting thin short fibers of 3d or less, the single yarn is rich in flexibility. Therefore, the pile produced from this single yarn is fine such as dust. House dust can be removed with high efficiency. However, since the single yarn lacks rigidity, the effect of removing the pile is insufficient for large house dust such as pet hair and human hair. Therefore, it is possible to remove dirt sufficiently by wiping the cleaning surface only once. Moreover, large house dust such as pet hair and human hair can be removed with high efficiency. There was a need to develop a pile fiber yarn that could be used and manufactured quickly and inexpensively. In particular, with respect to the cleaning effect on large house dust such as pet hair and human hair, there is room for improvement in the conventional mop, and is therefore the main object of the present invention.

  The present invention has been made to solve the above-mentioned problems, and the first embodiment of the present invention is formed by twisting one or more single yarns together to form a raw yarn and twisting a plurality of the above-mentioned raw yarns. A pile fiber yarn, wherein the plurality of raw yarns include at least a first raw yarn having the maximum thickness and a second raw yarn having the next thickest thickness, A first convex portion is formed by the first raw yarn on a surface in a fiber direction, a second convex portion is formed by the second raw yarn, and the fiber is formed by a difference in height between the first convex portion and the second convex portion. It is the fiber yarn for piles which forms an uneven | corrugated pattern in the surface of a direction.

  The 2nd form of this invention is the fiber yarn for pile which makes the height difference of the said 1st convex part and the said 2nd convex part 0.1 mm or more.

  In the third aspect of the present invention, the single yarn forming the first raw yarn and the single yarn forming the second raw yarn are set to the same thickness, and N1 single yarns are twisted to form the first original yarn. A single yarn is twisted to form a second raw yarn, and the number N1 is set to be one or more larger than the number N2, whereby the thickness of the first raw yarn is thicker than the thickness of the second raw yarn It is the fiber yarn for pile made to become.

  The 4th form of this invention is the fiber yarn for pile which sets the difference of the said number N1 and the said number N2 to 1-30, and forms the height difference of the said uneven | corrugated pattern.

  According to a fifth aspect of the present invention, N1 yarns are twisted to form a first yarn, N2 yarns are twisted to form a second yarn, and the number N1 is set equal to the number N2. By setting the thickness of the single yarn forming the first raw yarn to be larger than the thickness of the single yarn forming the second raw yarn, the thickness of the first raw yarn is set to be the second raw yarn. It is a fiber yarn for piles which is made thicker than the thickness of.

  In a sixth aspect of the present invention, N1 single yarns are twisted to form a first raw yarn, N2 single yarns are twisted to form a second raw yarn, and the number N1 and the number N2 are different. By setting the thickness of the single yarn forming the first raw yarn and the thickness of the single yarn forming the second raw yarn to be different, the thickness of the first raw yarn is The pile fiber yarn is thicker than the thickness of the second raw yarn.

  A seventh embodiment of the present invention is a pile fiber yarn in which the thickness of the single yarn is 1S (British count) to 30S (British count).

  An eighth aspect of the present invention is a pile fiber yarn in which the single yarn is made of a synthetic fiber.

  A ninth aspect of the present invention is a pile fiber yarn in which the synthetic fiber is nylon.

  The 10th form of this invention is a wiping body which formed many piles using the fiber yarn for piles in any of the 1st-9th form.

  The 11th form of this invention is the cleaning tool which mounted | wore the wiping body holding | grip part with the wiping body in a 10th form.

  According to the first aspect of the present invention, the first convex portion is formed by the first raw yarn on the surface in the fiber direction of the pile fiber yarn, and the second convex portion is formed by the second raw yarn, The unevenness pattern is formed on the surface in the fiber direction due to the height difference between the first protrusion and the second protrusion, so that when house dust is cleaned by a mop equipped with the pile fiber yarn as a pile, It gets into the uneven pattern and is removed. Therefore, a mop having a high cleaning power can be obtained. In addition, the shape of the uneven pattern of the pile fiber yarn of this embodiment is a size that is just enough to allow house dust of a size such as pet hair or human hair to enter. Therefore, a mop having a high cleaning power for pet hair and human hair can be obtained by the uneven pattern. Furthermore, since the pile fiber yarn of this form is manufactured by the same material and manufacturing method as the conventional pile fiber yarn, there is no need of a new raw material and an installation, and manufacture can be started very cheaply and rapidly.

  In the present embodiment, the plurality of raw yarns include at least a first raw yarn having the maximum thickness and a second raw yarn having the next largest thickness. To produce the first and second raw yarns having different thicknesses, the same single yarn is used for producing the first and second raw yarns, and the number of single yarns used for the first raw yarn, There is a method of making the number of single yarns used for the second raw yarn different. There is also a method in which the thickness of the single yarn (first single yarn) forming the first raw yarn is thicker than the thickness of the single yarn (second single yarn) forming the second raw yarn. Of course, a combination of these methods may be used.

The first raw yarn and the second raw yarn in this embodiment may be formed from a plurality of single yarns, or may be formed from only one single yarn. The material may be natural fibers such as cotton, chemical fibers such as nylon, or a mixture thereof. When natural fiber is used, a pile excellent in water absorption is obtained. When chemical fiber is used, a pile excellent in durability and cleanability can be obtained. In this embodiment, a pile fiber yarn may be manufactured by twisting together a first yarn and a second yarn together with a yarn having a thickness smaller than that of the second yarn. In this example, it was found that the pet hair collecting property of the pile depends only on the height difference between the first convex portion of the first raw yarn and the second convex portion of the second raw yarn. By twisting the yarn, the strength and durability of the pile fiber yarn can be increased.
When the first raw yarn and / or the second raw yarn is composed of a single yarn, the single yarn may be formed by spinning a large number of short (about 30 to 80 mm) short fibers. Many natural fibers are short fibers such as cotton, but chemical fibers are sometimes cut into short fibers such as filament yarns to form short fibers. By producing single yarn by spinning short fibers, a single yarn having a large number of fine fluff on the surface and innumerable fine pores inside is obtained, and a fiber yarn for pile is produced from this single yarn. By doing so, a pile having a high house dust collecting property can be expected. In fact, in pile manufacturing, it is common to use short fibers rather than long fibers. Denier (d) is used as a unit representing the thickness of the short fiber. The larger the denier number, the thicker the short fiber. The thinner the short fiber, the higher the flexibility of the formed single yarn and the finer the surface fluff and the internal hole, the higher the efficiency of removing fine house dust such as dust. On the other hand, the thicker the short fiber, the higher the rigidity of the formed single yarn, and thus the higher the efficiency of removing coarse house dust by the pile. The thickness of the short fiber in this embodiment is preferably 10d or less, more preferably 6d or less.

  According to the second aspect of the present invention, since the height difference between the first convex portion and the second convex portion is 0.1 mm or more, the concave / convex pattern becomes deep, and the concave / convex pattern easily surrounds the house dust. Become. Accordingly, it is possible to obtain a pile excellent in the collection property of large house dust such as pet hair and human hair. According to the inventor's experiment, when the height difference is 0.1 mm or more, the pet hair collecting property of the pile is improved, and when the height difference is 0.2 mm or more, the pet hair Collectability is further improved.

  According to the third aspect of the present invention, the single yarn forming the first raw yarn and the single yarn forming the second raw yarn are set to the same thickness, and the single yarn is twisted by N1 yarns. 1 yarn, N2 single yarns are twisted to make 2nd yarn, and the number N1 is set to be one or more larger than the number N2, so the first yarn and the second yarn are formed from one type of single yarn By adjusting only the number N1 and the number N2, it is possible to appropriately set the difference in thickness between the first raw yarn and the second raw yarn. Therefore, the pile fiber yarn having the concavo-convex pattern in the first embodiment can be manufactured inexpensively and rapidly. However, the single yarn forming the first raw yarn and the single yarn forming the second raw yarn may be different in material and / or structure and may be set so that only the thickness is the same.

  According to the fourth aspect of the present invention, the difference between the number N1 and the number N2 is set to 1-30 to form the height difference of the uneven pattern, so the thickness of the single yarn used and the pile An appropriate difference in the number of yarns can be set according to the ease of production of the fiber yarn. As the thickness difference between the first raw yarn and the second raw yarn increases, the height difference increases, and the house dust collecting property by the uneven pattern increases. However, as the difference in thickness increases, it becomes more difficult to twist the first raw yarn and the second raw yarn, and the ease of production of the pile fiber yarn is reduced. Therefore, there is an upper limit to the difference in the number of single yarns that can actually be used. However, according to the experiments of the present inventor, when a sufficiently thin single yarn (for example, 30S) is used, it is possible to produce a fiber yarn for pile even if the difference in the number of single yarns is about 30. The fiber yarn for pile exhibits excellent pet hair collecting properties in a cleaning test. Moreover, in order to be able to confirm the improvement of the house dust collecting property by the uneven pattern, the difference in the number of single yarns needs to be sufficiently large, but when sufficiently thick single yarns (for example, 1S or 5S) are used. Even if the difference in the number of single yarns is 1, a sufficiently large height difference can be secured, and thus a pile fiber yarn having a high house dust collecting property can be obtained.

  According to the fifth aspect of the present invention, the number N1 is set equal to the number N2, and the thickness of the single yarn forming the first raw yarn is set to the thickness of the single yarn forming the second raw yarn. Since the thickness of the first raw yarn is set to be thicker than the thickness of the second raw yarn by setting it thicker than the thickness, the first raw yarn and the second raw yarn are produced from different types of single yarn. It is possible to increase the manufacturing flexibility of the pile fiber yarn. In order to produce the first single yarn and the second single yarn having different thicknesses, the same type of short fibers may be used and the number of short fibers may be set differently. Two types of short fibers having different thicknesses may be used. In this embodiment, the first single yarn and the second single yarn having different materials and / or structures can be easily used. For example, natural fibers are used for the first single yarn to increase water absorption, and the second short fiber is used. It is also easy to increase the strength using chemical fibers.

  According to the sixth aspect of the present invention, the number N1 is set to be different from the number N2, and the thickness of the single yarn forming the first raw yarn and the single yarn forming the second raw yarn are set. Since the thickness of the first raw yarn is set to be thicker than the thickness of the second raw yarn, the manufacturing flexibility of the pile fiber yarn can be further increased. . When the first raw yarn is manufactured, the first raw yarn can be set thicker than the second raw yarn by setting both the number N1 and the thickness of the single yarn larger than the second raw yarn. However, in order to implement this embodiment, for example, the thickness of the single yarn in the first raw yarn can be set thin, and the thickness of the raw yarn can be set thick by setting the number N1 large, It is also possible to set the thickness of the original yarn thick by setting the number N1 small and setting the thickness of the single yarn thick.

  According to the seventh aspect of the present invention, since the thickness of the single yarn is 1S (British count) to 30S (British count), the fiber yarn for piles is excellent in flexibility and house dust collecting ability. Can be formed. The thickness of a single yarn is represented by S (British count), and the larger the number, 1S, 2S, 3S, the thinner the single yarn, the more pile fiber yarn formed from 4S or more single yarn It is very flexible. The inventors of the present invention changed various British yarn counts of single yarns to form various pile fiber yarns, produced piles from the pile fiber yarns, and tested pet hair collecting ability. As a result, if piles are made using fiber yarns for piles based on single yarns with a thickness of 1S to 30S, it is possible to form piles for mop that collects pet hair and human hair and has good water absorption. I found it possible. A single yarn of 1S or more is thin and flexible, but if it becomes too thin, the elasticity and durability of the fiber will decrease. The present inventors have discovered that the thickness of a single yarn is 30S or less as a limit of elasticity and durability of a mop pile. Therefore, if a pile fiber yarn is formed by appropriately selecting a single yarn of 1S to 30S according to the fiber type, a pile having elasticity and durability and good house dust collecting property is produced. it can. In the following description, since S represents an English type count, explanation will be made mainly using the symbol S, and the English type count will be omitted.

  According to the 8th form of this invention, since the said single yarn consists of synthetic fibers, the fiber yarn for piles with high durability and high cleaning property can be obtained. The synthetic fiber here includes chemical fibers such as nylon. In such chemical fibers, there are cases where long fibers such as filament yarn are cut short to form short fibers. However, a long-fiber chemical fiber such as the filament yarn may be used as it is as a single yarn.

  According to the ninth aspect of the present invention, since the synthetic fiber is nylon, the most widespread nylon can be used as a pile material, and the pile can be manufactured inexpensively and rapidly. Nylon as a pile material has been extensively researched and many types are in circulation, so the material can be selected appropriately according to the intended use.

  According to the 10th form of this invention, since the wiping body is formed using many piles using the pile fiber yarn in any of the 1st-9th form, the collection property of house dust is high. A wiping body is obtained. The wiping body in the present embodiment is excellent in flexibility and elasticity, and in addition, is excellent in trapping house dust such as pet hair and human hair. If synthetic fibers are used for the pile or mop base fabric, a mop having excellent wear resistance can be provided.

  According to the 11th form of this invention, since the wiping body in a 10th form is mounted | worn with a wiping body holding part, the cleaning tool with high cleaning efficiency can be obtained. If the pile of this invention is used for the pile which comprises this mop, the cleaning tool which is flexible and has a good house dust collection property can be provided. If synthetic fibers are used for the mop of this cleaning tool, it is possible to provide a cleaning tool that is more excellent in wear resistance and prevent quality deterioration due to multiple washings. Since this cleaning tool is excellent in house dust collection property and excellent in cleaning properties, particularly in removing pet hair and human hair, it can be used not only for home use but also for business use.

The mop 2 includes an elliptical mop base fabric 4 and a large number of piles 8 planted on the lower surface thereof. As the planting method, various known methods such as sewing and fusion can be used. The mop base fabric 4 is formed by weaving cotton fibers or synthetic fibers in a mesh shape, and bag-like portions 6 and 6 made of the same fiber type are provided on the upper surface of the mop base fabric 4. The bag-like portions 6 and 6 are for mounting end portions 14a and 14a of the gripping portion 14 to be described later, and are arranged so that the openings of the bag-like portions 6 and 6 face each other.

Good.

FIG. 2 is a diagram illustrating the formation of pile fiber yarns in this embodiment. (2A) is an explanatory diagram for forming the single yarn 52 by twisting the short fibers 50 together. The length of the short fiber 50 is, for example, about 30 to 80 mm, and a single yarn 52 is formed by twisting a large number of these short fibers 50. Many natural fibers are short fibers such as cotton, but chemical fibers are sometimes cut into short fibers such as filament yarns to form short fibers. In the present embodiment, the thickness of the short fiber is preferably 10d or less, more preferably 6d or less. 2 to 4, the single yarn 52 is formed by twisting a large number of short fibers 50, but the single yarn 52 may be formed of a smaller number of long fibers. Moreover, the single yarn 52 may be formed from only one long fiber.
(2B) represents the single yarn 52. In (2B), a large number of short fibers 50 are aligned and twisted in parallel to form a single yarn 52. However, a long-fiber chemical fiber such as the filament yarn may be used as it is as a single yarn 52. The thickness of the single yarn 52 is represented by S, and various thicknesses can be formed. The average thickness of the single yarn 52 used in the pile fiber yarn of the present invention is at least 1 S or more, and is preferably adjusted to 1 S or more and 30 S or less. A plurality of single yarns 52 are twisted to form a raw yarn 54.

By changing the type of the single yarn 52, various first raw yarns 54a can be created, and a first raw yarn 54a composed of a plurality of types of blends can also be formed. There are various ways of twisting the first raw yarn 54a and the number of times, and the first yarn 54a is appropriately adjusted according to the purpose.
(2D) represents a second raw yarn 54b composed of five single yarns 52. The second raw yarn 54b in (2D) is the same type as the first raw yarn except that the thickness is thinner than that of the first raw yarn 54a, and the twisting method and the number of times of the second raw yarn 54b are various. And is appropriately adjusted according to the purpose.
(2E) is a pile fiber yarn 56 formed by twisting the first raw yarn 54a and the second raw yarn 54b. On the surface of the pile fiber yarn 56 in the fiber direction, the first raw yarn 54a forms a first convex portion 60 protruding radially from the central axis of the pile fiber yarn 56, and the second raw yarn 54b is formed. Then, a second convex portion 62 is formed that projects radially from the central axis of the pile fiber yarn 56. Since the thickness of the first raw yarn 54a is larger than the thickness of the second raw yarn 54b, the first convex portion 60 and the second convex portion 62 form a height difference 66, and the pile fiber yarn 56 is formed by the height difference 66. An uneven pattern 68 is formed on the surface in the fiber direction. The height difference 66 here is preferably 0.1 mm or more, and more preferably 0.2 mm or more. The pile 8 of the mop 2 shown in FIG. 1 is formed from the pile fiber yarn 56. When cleaning is performed using the mop 2, house dust enters the uneven pattern 68 of the pile 8 and is removed.

FIG. 3 is a diagram illustrating formation of pile fiber yarns in which the first single yarn is thicker than the second single yarn in the present embodiment. (3A) is an explanatory view of twisting a relatively large number of short fibers 50 to form a first single yarn 52a having a relatively large thickness. Similar to the embodiment in FIG. 2, the short fibers 50 may be natural fibers or chemical fibers. Further, long fibers may be used instead of the short fibers 50.
(3B) represents the first single yarn 52a. The first single yarn 52a is thicker than a second single yarn 52b, which will be described later. If this condition is satisfied, one having an average thickness of 1S or more can be used. (3C) represents a first raw yarn 54a formed from five first single yarns 52a. As in (2C) of FIG. 2, various first raw yarns 54a can be created by changing the type of the first single yarn 52a, and the first raw yarn 54a composed of a plurality of types of blends can also be formed. There are various ways of twisting the first raw yarn 54a and the number of times, and the first yarn 54a is appropriately adjusted according to the purpose.
(3D) is an explanatory diagram for forming a second single yarn 52b having a thickness smaller than that of the first single yarn 52a from the same short fibers 50 as in (3A). The short fibers 50 per unit length of the second single yarn 52b in (3D) are less than the short fibers 50 per unit length of the first single yarn 52a in (3A). (3E) represents the second single yarn 52b. The second single yarn 52b is thinner than the first single yarn 52a described above, but if this condition is satisfied, one having an average thickness of 1S or more can be used.
(3F) represents a second raw yarn 54b formed from five second single yarns 52b. The number of second single yarns 52b constituting the second raw yarn 54b in FIG. 3 is the same as the number of first single yarns 52a constituting the first raw yarn 54a. Accordingly, the difference in thickness between the first raw yarn 54a and the second raw yarn 54b is caused only by the difference in thickness between the first single yarn 52a and the second single yarn 52b. The second raw yarn 54b in (3F) is the same type as the first raw yarn except that the thickness is thinner than the first raw yarn 54a in (3C).

As in (2E) of FIG. 2, on the surface in the fiber direction of the pile fiber yarn 56, the first original yarn 54a projects from the central axis of the pile fiber yarn 56 in the radial direction. The second raw yarn 54b forms a second convex portion 62 that protrudes in the radial direction from the central axis of the pile fiber yarn 56. Since the thickness of the first raw yarn 54a is larger than the thickness of the second raw yarn 54b, the first convex portion 60 and the second convex portion 62 form a height difference 66, and the pile fiber yarn 56 is formed by the height difference 66. An uneven pattern 68 is formed on the surface in the fiber direction. The pile 8 of the mop 2 shown in FIG. 1 is formed from the pile fiber yarn 56, and the uneven pattern 68 of the pile 8 surrounds and removes the house dust.

Further, the material of the second short fibers 50b may be different from the material of the first short fibers 50a.
(4E) represents the second single yarn 52b, and (4F) represents the second raw yarn 54b formed from the five second single yarns 52b. The explanations in (3E) and (3F) of FIG. 3 are also applicable to (4E) and (4F), and are therefore omitted here.
(4G) is a pile fiber yarn 56 formed by twisting together the first raw yarn 54a of (4C) and the second raw yarn 54b of (4F). Similar to (2E) in FIG. 2 and (3G) in FIG. 3, on the surface in the fiber direction of the pile fiber yarn 56, the first original yarn 54a is radially directed from the central axis of the pile fiber yarn 56. A protruding first convex portion 60 is formed, and the second raw yarn 54 b forms a second convex portion 62 protruding in the radial direction from the central axis of the pile fiber yarn 56. Since the thickness of the first raw yarn 54a is larger than the thickness of the second raw yarn 54b, the first convex portion 60 and the second convex portion 62 form a height difference 66, and the pile fiber yarn 56 is formed by the height difference 66. An uneven pattern 68 is formed on the surface in the fiber direction. The pile 8 of the mop 2 shown in FIG. 1 is formed from the pile fiber yarn 56, and the uneven pattern 68 of the pile 8 surrounds and removes the house dust.

  FIG. 5 is a schematic explanatory diagram when the pile fiber yarn in this embodiment is formed from three single yarns having different thicknesses. The pile fiber yarn in FIG. 5 has a third raw yarn 54a whose thickness is further thinner than the second raw yarn 54b, in addition to the first raw yarn 54a having a relatively large thickness and the second raw yarn 54b having a relatively small thickness. It is formed from the raw yarn 54c. The third raw yarn 54c may be formed from a single yarn 52 that forms both the first raw yarn 54a and the second raw yarn 54b, and is thinner than the second single yarn 52b that forms the second raw yarn 54b. You may form from the 3rd single yarn 52c. In the examples described later, it was found that it depends only on the difference in thickness between the first raw yarn 54a and the second raw yarn 54b and hardly depends on the thickness of the third raw yarn 54c. Therefore, in the pile fiber yarn 56 of FIG. 5, the height difference 66 between the first convex portion 60 formed by the first raw yarn 54a and the second convex portion 62 formed by the second raw yarn 54b is shown. .

  In the description of the following examples, d represents denier and S represents English count, that is, cotton count. Therefore, description will be made mainly using the symbols d and S, and the letters of denier and English count are omitted. To do. In this example, all single yarns are formed from short fibers. As already described, in the production of the fiber yarn for mop, the short fiber is used more widely than the long fiber. Therefore, also in this embodiment, the fiber yarn for mop is formed from the short fiber. In this embodiment, nylon fibers are used as the short fibers. As the nylon fibers, three types of short fibers of 1d, 3d, and 6d were prepared in Examples 1 to 60. For each of these short fibers, four types of single yarns of 5S, 10S, 20S, and 30S were formed. In the case of twisting a plurality of these single yarns, the yarns were twisted at a rate of 1 to 2 times / inch to obtain a raw yarn. Two or three of these yarns were aligned and twisted at a rate of 2 to 3 times / inch to produce a pile fiber yarn. When manufacturing these pile fiber yarns, ease of manufacture (production) was confirmed.

  This pile fiber yarn was planted as a pile on a base fabric to form a mop. These mops were supplied to a household where dogs and cats (pets) were not affected by hair loss and subjected to cleaning for one week, and then a check test was conducted on the pet's ability to collect pet hair. After collecting these mops and washing them under the same conditions, a confirmation test was conducted on the pet hair removal properties (washing removal properties) after washing.

[Examples 1 to 60] When the number of yarns is varied while keeping the single yarn constant For Examples 1 to 60, the thicknesses of the single yarn and the short fiber forming the first raw yarn and the second raw yarn are constant. In addition, by using a larger number of single yarns than the second raw yarn in the first raw yarn, the thicknesses of the first and second raw yarns were varied.

  Table 1 shows Examples 1-24 using 1d short fibers. Single yarns of 5S, 10S, 20S, and 30S were produced from the short fibers, and first and second yarns were produced from these single yarns. A pile fiber yarn is manufactured by twisting the first and second yarns made from the same single yarn, and a mop is produced using these pile fiber yarns as a pile. A confirmation test was conducted. After these mops were used, a cleaning test was conducted to confirm the cleaning removal property of the pet hair. When 30S single yarn was used, in order to secure the strength of the first raw yarn, more single yarns were used in the production of the first raw yarn than in the case of 20S or less.

  In the case where a relatively thick single yarn was used (5S, Examples 1 to 6), even if the difference in the number of single yarns N1 to N2 was about 1, an improvement in the pet hair collecting property was observed. However, when a relatively thin single yarn is used (10S or more, Examples 7 to 24), the difference in the number of single yarns N1−N2 is required to be 2 or more in order to confirm the improvement of pet hair collection. Met. When a relatively thick single yarn is used, even if the difference in the number of single yarns is about 1, the difference in the thickness of the single yarn is large. Therefore, the difference in height between the first and second convex portions is It is considered that the value is sufficient to improve the concentration.

As the difference N1-N2 in the number of single yarns was higher, there was a tendency for the mop to collect pet hair. About this, when the height difference of a 1st convex part and a 2nd convex part becomes a fixed value or more, it has shown that pet hair etc. enter easily into the uneven | corrugated pattern formed by this height difference. However, the higher the difference N1-N2 in the number of single yarns, the more difficult it is to twist the first and second raw yarns having different thicknesses, and it becomes more difficult to ensure the strength of the second raw yarn. Therefore, the ease of production of pile fiber yarns decreases. This tendency becomes more prominent as the thickness of the second single yarn becomes thinner. In particular, in Example 48, the difference N1-N2 in the number of single yarns is particularly increased using a particularly thin single yarn (30S) ( Since N1-N2 = 30), it is particularly difficult to manufacture the fiber yarn for pile. However, the pile fiber yarn of Example 48 can be manufactured to such an extent that it can be used in this test, and has a particularly high pet hair collecting property, so that it has sufficient practicality.
In addition, when the single yarn is particularly thin (20S and 30S), when the difference N1-N2 in the number of single yarns is 0 or 1 (Examples 13, 14, 19, and 20), the pet hair collecting property is high. When the difference was 2 or more (Examples 15 to 18, 21 to 24), the pet hair collecting property was drastically improved, and a relatively thick single yarn was used. As a result, it was confirmed that there was no inferiority in the collection. In these examples, thin single yarns (20S and 30S) are produced using particularly thin short fibers (1d), so that the pile formed has a very high flexibility. Originally, such a soft pile is not suitable for scraping rough house dust such as pet hair and human hair. However, by forming a concave / convex pattern with a height difference on the surface of the pile fiber yarn, pet hair, human hair, fiber waste, and the like can be cleaned and removed with high efficiency even in a soft pile.
As above-mentioned, in Examples 1-24, since the thin short fiber is used, the pile formed has a high softness | flexibility. When the pile is soft, the pet hair can be easily removed by washing the mop after use. Therefore, the cleaning removal property of pet hair in Examples 1 to 24 is generally good.

  Table 2 shows the actual measurement values obtained by actually measuring the height difference between the first convex portion and the second convex portion in the pile fiber yarns of Examples 7 to 12. In Table 1, although the improvement of pet hair collection property is seen from Examples 8 to 9, in Table 2, the height difference between Examples 8 and 9 changes from 0.09 mm to 0.17 mm. I understand that. Moreover, in Table 1, although further improvement of pet hair collection property is seen over Examples 9 to 10, in Table 2, the height difference in Examples 9 and 10 is from 0.17 mm to 0.42 mm. You can see that it is changing. That is, when the height difference exceeds 0.1 mm, the pet hair collecting property is improved, and when the height difference further exceeds 0.2 mm, the pet hair collecting property is further improved.

  Table 3 shows Examples 25-48 using 3d short fibers. Table 4 also shows Examples 49-60 using 6d short fibers. The thickness of the single yarn and the combination of the single yarn in the first and second raw yarns are the same as those in Examples 1 to 24 in Table 1. About pet hair collection property, although it improved slightly compared with Examples 1-24 using 1d short fiber, there is no useful difference and pet hair collection property is the 1st convex part and the 2nd. It can be seen that the height depends substantially on the height difference of the convex portion. However, in order to produce thin single yarns using thick short fibers, various devices are required. In particular, the production of 20S and 30S single yarns using 3d short fibers (Examples) Production of 10S, 20S, and 30S single yarns using 20-48) and 6d short fibers (Examples 55-72) led to a decrease in the productivity of pile fiber yarns. In particular, the production of 20S and 30S single yarns using 6d short fibers (Examples 61-72) requires considerable care, and therefore “×” (difficult) for the ease of production of pile fiber yarns. There was also an example. However, the pile fiber yarns of Examples 20 to 48 and 55 to 72 can be manufactured to such an extent that they can be used in this test, including those that are easy to produce, and have good pet hair collecting properties. In addition, it has sufficient practical utility since it has cleaning and removal properties.

[Examples 73 to 88] The thickness of the single yarn is variable and the number is fixed. In Examples 73 to 88, the number of single yarns in the first yarn is the same as the number of single yarns in the second yarn. The thickness of the first yarn is made thicker than the thickness of the second yarn by making the thickness of the single yarn in the first yarn larger than the thickness of the single yarn in the second yarn.

  Table 5 shows Examples 73 to 80 in which the number N1 of the first single yarn constituting the first raw yarn is the same as the number N2 of the second single yarn forming the second raw yarn (N1 = N2 = 6). Indicates. Single yarns of 1S, 4S, 7S, 10S, 15S and 20S were produced from 1d or 3d short fibers. A first raw yarn and a second raw yarn were produced by twisting six single yarns. A fiber yarn for pile was manufactured by twisting together the first and second raw yarns having different thicknesses. A mop was produced using this pile fiber yarn, and a confirmation test was conducted on the collection property of pet hair.

  In Examples 73 to 76, 1d short fibers were used, and in Examples 77 to 80, 3d short fibers were used. As in Examples 1 to 72 in Tables 1 to 4, the greater the difference in thickness between the first and second raw yarns, the better the collection of pet hair and the easier production of pile fiber yarns. It can be seen that the performance decreases. Regarding the washing and removing property of pet hair, the pile formed from the 1d short fibers was better than the pile formed from the 3d short fibers.

  In the present invention, each of the first raw yarn and the second raw yarn may be formed of only one single yarn. Table 6 shows Examples 81 to 88 in which one first single yarn forms a first raw yarn and one second single yarn forms a second raw yarn. In these examples, relatively thick 3d short fibers were used. Moreover, in order to ensure the strength of the raw yarn, relatively thick 1S, 2S, 3S and 4S single yarns were used. Similar to Examples 1 to 80 in Tables 1 to 5, the pet hair collecting property is improved as the difference in thickness between the first and second raw yarns increases. Further, since the process of twisting the single yarn to produce the raw yarn is omitted, the production is easy, and therefore the productivity of the fiber yarn for pile is good. Furthermore, since the pile fiber yarn is relatively thin and rich in flexibility, the pet hair can be easily washed and removed.

[Examples 89 to 92] Variable thickness of single yarn short fiber Table 7 shows examples in which the thickness of single yarn and raw yarn was changed by changing the thickness of the short fiber used for the single yarn. 89-92 are shown. The number of first short fibers forming the first single yarn and the number of second short fibers forming the second single yarn are both 400. Further, the number of first single yarns forming the first raw yarn and the number of second single yarns forming the second raw yarn are both 6. In these examples, 0.5d, 1d, 3d and 5d staple fibers were used. As in Examples 1 to 88 in Tables 1 to 6, the greater the difference in thickness between the first and second raw yarns, the better the collection of pet hair and the easier production of fiber yarns for piles. It can be seen that the performance decreases. In addition, the pet hair was well washed and removed.

[Examples 93 to 96] Both the thickness and the number of single yarns are variable Table 8 shows Examples 93 to 96 in which both the thickness and the number of single yarns are variable. In Example 95, the first single yarn is thinner than the second single yarn, but the first raw yarn is thicker than the second raw yarn by twisting a large number of the first single yarn. In Example 96, the number N1 of the first single yarns is smaller than the number N2 of the second single yarns. However, by making the first single yarn much thicker than the second single yarn, 2 Thicker than the original yarn. Also in these examples, the greater the difference between the thicknesses of the first and second raw yarns, the better the collection of pet hair and the lower the productivity of pile fiber yarns. I understand. In Examples 93 to 96, since relatively short 1d short fibers are used, the pile fiber yarns have high flexibility, and therefore the pet hairs are also easily washed and removed.

[Examples 97 to 100] Third Raw Yarn Table 9 shows Examples 97 to 100 in which a pile fiber yarn was formed from three raw yarns. The first raw yarn and the second raw yarn are the same as those in Examples 7 to 12 in Table 1, and a single yarn having a smaller number than the second raw yarn was used as the third raw yarn. That is, a 10S single yarn was manufactured using 1d short fibers, and the thickness of the raw yarn was changed by changing the number of single yarns. The pet hair collecting property in Examples 97 to 100 was the same as that in Examples 7 to 12 using the same first and second raw yarns, and there was almost no influence of the third raw yarns.

  Pile made from pile fiber yarns with uneven patterns due to the difference in height between the first and second protrusions is a highly efficient collection of large house dust such as pet hair and human hair and sufficient production Has ease. This height difference can be easily set by appropriately setting the number and / or thickness of single yarns constituting the raw yarn. Therefore, the mop produced by using the pile and the mop base fabric according to the present invention can be used not only for home use but also widely used in general industries.
