Description

[Detailed description of the invention] Industrial field of application This invention relates to an improved dirt-removing thread for use in motsupu, dustless mats, which are floor cleaning tools. By twisting heat-melting synthetic fibers to form an extremely narrow synthetic resin fused area, each spun cotton yarn itself and the twisted yarn are prevented from fraying, tangling, and fluffing through this synthetic resin fused area. , and is designed to improve work efficiency and extend service life.

Conventional technology The brush part of a motsupu is made up of multiple strings made of twisted yarns made of natural or synthetic fibers, and the tips of each string remain separated. From this part, the mutual twists of the spun yarn tend to return and the tip becomes a single spun yarn with a spiral shape.On the other hand, because this part needs to be squeezed and washed in water during use or recycling cleaning, the spun yarn is worn out and becomes a yarn. There are many disadvantages in that it generates dust and lint, and the strings become entangled with each other.

For this reason, in recent years, synthetic resin core material has been interposed in the center of spun yarns that are twisted together, or a center yarn with a synthetic resin agent attached to the outer periphery has been introduced in the center of twisted spun yarns. something is being developed.

Problems that the invention aims to solve However, in these products that have a core made of synthetic resin or thread to which synthetic resin is attached,
Since the core runs directly through the center of the threads that surround it and are mutually bent, there is a disadvantage that the core is likely to break if the entire core is pulled strongly.

To this end, instead of providing the core, it may be possible to attach a synthetic resin to the surface of the spun yarn itself to reinforce it, but in this way, the spun yarn becomes hard and Since it is inevitably water-repellent, the function of retaining a large amount of moisture and special oil in the brush part, which is necessary for motsupu, is impaired.

Means to Solve the Problem In contrast, in this invention, heat-melt synthetic fibers are twisted in advance into one or both of the two spun cotton threads that make up the twisted string used in the brush part, and then heated and melted. A series of narrow synthetic resin fused parts are formed, and the spun cotton yarns are bonded to each other through the synthetic resin fused parts to prevent fraying, tangling, and fluffing of the strings, and to strengthen them.

Example Figures 1 and 2 show the state in which the method was applied to the cord of a motsupu. As shown in FIG. 1, a large number of string strips 3... are planted in rows on the crossbar 2 connected to the handle rod 1 to form the whole, and as shown in FIG. is a twisted yarn, and one of the two spun cotton yarns 4 and 5 forming this yarn is twisted with heat-melting synthetic fiber in advance, and a resin fused portion 6 is formed by heating and melting it. The spun cotton yarns 4 and 5 are bonded to each other at various locations by this synthetic resin fused portion 6.

In the embodiment shown in FIG. 2, this synthetic resin fused portion 6 is attached to only one of the two spun cotton yarns 4 and 5, but it may be provided to each of the two yarns.

To form this synthetic resin fused portion 6, a string strip 3 is used.
In manufacturing a series of materials that will be the raw materials for the above, one or more heat-melting synthetic fibers 6' are added to either or both of the two spun cotton yarns 4 and 5 in advance.
are twisted into a single thread, which is then heated with steam,
The synthetic fiber 6' is heated by high frequency, infrared heating, etc. to melt it and absorbed by one or both of the spun cotton yarns 4 and 5 to form the synthetic resin fused portion 6. These spun cotton yarns 4 and 5 are heat-meltable synthetic fibers 6'
In order to combine them, the necessary synthetic fibers are mixed with the fibers constituting the spun cotton yarn to form the spun cotton yarn. In addition, when the raw material produced above is colored in a desired color, it is necessary to process it at a low temperature so that the synthetic resin dyed part is not melted away. FIG. 3 is a perspective view showing a dustless mat using the improved yarn of this invention, and the shape can be arbitrarily selected from not only a square shape but also a circular shape, an elliptical shape, etc.

Effects of the invention In the improved dirt removal method of this invention, the spun cotton yarn itself is provided with a series of narrow synthetic resin fused parts 6 over its entire length, and the two spun cotton yarns are connected through this. Since 4 and 5 are bonded to each other at various places, there is no unraveling due to untwisting of the two, and there is no fraying from the cut end of the formed string 3, and each spun cotton yarn itself is Since it is fixed by a narrow fused portion, it has the advantage that less thread waste is generated during use.

Since the fused portion of each spun cotton yarn is narrow,
There is no hardening of the string or reduction in water absorbency, and therefore cleaning water, floor oil, etc. can be handled in exactly the same way as conventional ones.
