Description

  The present invention relates to a twisted yarn for mop that is used for a wiping portion of a mop that is a cleaning tool and that captures and holds dust, and a method for manufacturing the same.

  Conventionally, two thick single yarns are twisted around the heat-sealed yarn and heat-bonded to the mop wiping part. Mop twisted yarns that are twisted without being used are well known.

  However, the twisted yarn for mop, in which two single yarns with a high count are twisted and heat-bonded around a heat-sealed yarn, is a hard twist, so there is little unevenness on the surface of the mop twist yarn. There is not much effect, and dust catchability is bad. In addition, since there is almost no gap for storing the captured dust, the dust retention is also poor. On the other hand, the twisted yarn for mop, which is a single twist of dozens of single yarns of fine counts without using a heat-sealing yarn, is easily twisted because it is twisted, and its durability is poor. In addition, the appearance of the hair is also bad because of the fluffiness. Each has its own problems.

  Therefore, Patent Document 1 discloses that a plurality of single yarns are aligned, twisted in the same direction as the twist direction of the single yarn, and then twisted, and a plurality of twisted yarns are twisted around a single heat-sealing yarn. A mop twisted yarn in which the twisted yarns are bonded together and heated is proposed.

  Comparing the above-mentioned two yarns of thick count with a mop twisted yarn that is twisted and heat-bonded around a heat-sealing yarn, the mop twisted yarn described in Patent Document 1 is obtained by twisting a plurality of yarns. Therefore, the irregularities on the surface of the twisted yarn are large. Therefore, it has a certain level of brushing effect and excels in dust trapping. In addition, since a gap for storing the captured dust exists to some extent between the single yarns, it is superior in dust retention.

  In addition, when comparing the above-mentioned ten yarns of fine yarn with a twisted yarn for mop that is not twisted without using a heat-sealing yarn, the yarn for mop described in Patent Document 1 has a single yarn that is a heat-sealing yarn. Since it is bonded by melting by heating, it is not easily frayed and has excellent durability.

However, in the twisted yarn for mop described in Patent Document 1, the single yarn is tightly tightened because the direction of the ground twist of the single yarn is the same as the direction of the lower twist. For this reason, the mop twisted yarn cannot be given a sense of volume, and the texture becomes very bad. Moreover, the unevenness | corrugation of the surface of the twisted yarn for mops does not become so big by tightening up single yarns. For this reason, the brushing effect is insufficient and the dust trapping property still does not meet the requirements. Further, similarly, due to the tight tightening of the single yarns, there are not enough gaps between the single yarns storing dust. For this reason, the dust holding ability still does not meet the requirements. As described above, the twisted yarn for mop described in Patent Document 1 has various problems to be overcome.

And a suitable number for producing a twisted yarn for mop that is excellent in dust capture and retention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The manufacturing method of the mop twist yarn 40 according to the present invention is divided into three steps, the first step of manufacturing the first twisted yarn 20 from the single yarn 10, and the second twisted yarn 30 from the first twisted yarn 20 and the low-melting-point nylon monofilament 21. And the third step of manufacturing the mop twist yarn 40 from the second twisted yarn 30 and the low melting point nylon monofilament 31. Each process will be described below.

  As shown in FIG. 1, in the first step, four Z-twisted fine count single yarns 10 are aligned, and the first twisted yarn 20 is twisted in an S twist opposite to the direction of twisting of the single yarn 10. Is manufactured.

  The thickness of the single yarn 10 used in the first step is not particularly limited, but by setting the cotton yarn count to 6-20, the mop twist yarn 40 has a good appearance and is excellent in dust trapping and retention. This is preferable. Further, the number of twists of the first twisted yarn 20 is not particularly limited, but it is 40 to 120 T / m, more preferably 60 to 90 T / m. Excellent retention. The number of single yarns 10 is four in this embodiment, but is not particularly limited to this. However, 2 to 8 yarns are suitable for making the mop twisted yarn 40 look good and having excellent dust capturing and retaining properties. Here, as the single yarn 10, cotton yarn, nylon, ester, acrylic, rayon, and a blended yarn thereof are preferably used to exhibit the function as a mop.

  As shown in FIG. 2, in the second step, two S-twisted first twisted yarns 20 are arranged and twisted in a Z-twisted direction opposite to the twisting direction of the first twisted yarn 20 around the low melting point nylon monofilament 21. The second twisted yarn 30 is manufactured by melting the low melting point nylon monofilament 21 by heat treatment and bonding the first twisted yarns 20 to each other.

  In the second step, the number of twists of the second twisted yarn 30 is not particularly limited, but it is 80 to 150 T / m, more preferably 100 to 130 T / m. It has excellent scavenging and retention properties. In addition, although the number of the 1st twisted yarn 20 was set to 2 in this embodiment, it is not restricted to this. However, in order to make the mop twisted yarn 40 look good and have excellent dust capturing and retaining properties, 2 to 4 yarns are suitable.

  In this embodiment, the first twisted yarn 20 is twisted around the low melting point nylon monofilament 21 in the second step. However, the second twisted yarn is obtained by combining only the first twisted yarn 20 without using the low melting point nylon monofilament 21. 30 may be manufactured.

  As shown in FIG. 3, in the third step, two Z-twisted second twisted yarns 30 are gathered and twisted in an S twist in the direction opposite to the direction of twisting of the second twisted yarn 30 around the low melting point nylon monofilament 31. The low melting point nylon monofilament 31 is melted by heat treatment and the second twisted yarns 30 are bonded to each other, whereby the mop twisted yarn 40 is manufactured.

  In the third step, the number of twists of the mop twist yarn 40 is not particularly limited. However, when the mop twist yarn 40 is 80 to 140 T / m, more preferably 100 to 120 T / m, the mop twist yarn 40 has a good texture and dust. It has excellent scavenging and retention properties. The number of the second twisted yarns 30 is two in this embodiment, but is not limited thereto. However, in order to make the mop twisted yarn 40 look good and have excellent dust capturing and retaining properties, 2 to 4 yarns are suitable.

  In this embodiment, the Z-twisted single yarn 10 is used, but an S-twisted yarn may be used. In this case, the first twisted yarn 20 is Z-twisted, the second twisted yarn 30 is S-twisted, the mop twisted yarn 40 is Z-twisted, and the twisting direction in each step is opposite to that of this embodiment. In this embodiment, the low melting point nylon monofilaments 21 and 31 are used to bond the twisted yarns 20 and the twisted yarns 30 to each other. However, other heat fusion yarns such as a low melting point nylon multifilament may be used. An alternative is also possible. Moreover, a well-known thing is used for the method of the twisting in each process, and the method of heat processing.

  In the twisted yarn 40 for mop manufactured by the above-described manufacturing method, the twisting direction of the twisted yarn in each step is opposite to the twisting direction of the twisted yarn in the previous step. As a result, it is rich in volume and has a soft texture. Further, since the single yarns are loosely tightened, the unevenness of the surface of the mop twist yarn 40 is increased, and a sufficient brushing effect can be provided, so that the dust capturing property is excellent. Furthermore, since the tightening between the single yarns is also loose, it is possible to form many gaps for storing the dust between the single yarns, and the dust retention is excellent. Furthermore, since the single yarns 10 are bonded to each other by the low melting point nylon monofilaments 21 and 31, fraying does not occur and sufficient durability is obtained. In addition, as a secondary effect of giving the volume to the mop twisted yarn 40, the weight of the entire mop can be reduced.
