When the fineness of each crimped multifilament is 300 denier or less, a large number of surface yarns are required to form the rag portion, resulting in an increase in cost. In addition, the performance of collecting large dust is deteriorated, which is not preferable. 20
When the denier is 000 denier or more, the surface weight of the surface yarn in the rag portion is small, so that the surface area of the entire surface yarn is small and the dust collecting performance is deteriorated, which is not preferable.

If the crimp extension ratio of each crimped multifilament is less than 5%, the bulk performance is too low, the dust collection performance is deteriorated, and the cleaning performance is deteriorated, which is not preferable.

Further, if the content of the carbon-containing nylon 6 crimped multifilament exceeds 5% of the whole, the dust collection performance is lowered and the cleaning performance tends to be impaired, which is not preferable.

The support 2 used in the present invention is nylon 6
Although it is a woven fabric, a non-woven fabric made of nylon 6, or a film made of nylon 6, nylon 6 can be reliably bonded to the surface yarn 1 made of nylon 6, the durability of the support itself is good, and the cost is low. A woven fabric or a nylon 6 non-woven fabric is more preferable, and these supports 2 are usually formed in a bag shape.

The handle 4 used in the present invention can be formed of plastic, metal, wood, etc., but in order to recycle (chemical recycle) including the handle body,
More preferably, it is made of nylon 6 resin.

As a method of connecting the support 2 and the handle 4, FIG.
In addition to the use of the connecting portion 5 made of the nylon 6 string shown in (2), a method of fusing them or joining them via an adhesive may be used.

Weaving and sewing are adopted as the manner of connecting the surface thread 1 to the support 2.

That is, in the case of weaving, as shown in FIG. 4, when the bag-shaped support 2 is folded, the surface yarn 1 is directly engaged with the bag skin by the loop-shaped weaving. In some cases, it is suitable for mops having short hairs such as loop (c), cut (b) or loop cut (d) shown in FIGS. 6 (b) to 6 (d).

Further, in the case of sewing, as shown in FIG. 5, when the bag-shaped support 2 is folded, the surface thread 1 is sewn and joined to the bag skin by the sewing thread 6, and in this case, Is suitable for a long-haired cut, that is, a mop in the form of a string, as shown in FIG. 6 (a).

The mop having the short cut hair is preferably used for the purpose of removing dust on a narrow place such as a desk or a car.

A mop having short loops or loop cuts on the hair is preferably used mainly for the purpose of removing dust from personal belongings such as bags, shoes, and clothes.

Further, the mop having a long-haired cut is preferably used mainly for removing dust in a wide area such as a floor surface, a ceiling, and a wall.

In the polyamide mop of the present invention having the above-mentioned constitution, the surface yarn is formed by the nylon 6 crimped fiber or the mixed fiber of the nylon 6 crimped fiber and the carbon-containing nylon 6 crimped fiber. As a result, there is little idle hair even after long-term use, and cleaning performance and durability are extremely superior.

Also, since the surface thread made of the crimped fiber made of nylon 6 is bonded to the nylon 6 support, or the handle portion is made of nylon 6 in addition to this, only the cloth portion is formed. Is removed and subjected to depolymerization, or the entire constituents of the mop are subjected to depolymerization as they are, so that recirculation to return to ε-caprolactam is possible and effective utilization of resources can be achieved.
