DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning substrate that is resistant to soiling .

[0002]

2. Description of the Related Art Conventionally, a plain or twill woven fabric made of polyester fiber, polyolefin fiber, vinylon fiber or the like , or a warp knit having a loop forming structure has been used as a cleaning substrate .
Earth is commonly used .

For example, Japanese Patent Application Laid-Open No. 4-352920 discloses
Uses polyester fiber as the warp and insertion yarns,
Rayon fiber with a single yarn fineness of 10 denier or more
A cleaning fabric for Raschel tissue used is disclosed.
Knitted fabric towels provide good cleaning, foaming and skin
It also describes that it gives a tactile sensation.

[0004] However, these conventional cleaning substrates are easily soiled, and when soiled, the soil is difficult to remove. Also sewable
Poor properties. If a hole is made, the yarn is apt to fray and the hole is enlarged, which is likely to be defective. As a result, there has been a problem that the number of uses is reduced (the durability is low).

[0005]

OBJECTS OF THE INVENTION The purpose of the present invention is to overcome such problems in the prior art. Sunawa ChiKiyoshi <br/> easily fall with less contamination due to scavenging, good availability sewing property
Accordingly, it is an object of the present invention to provide a cleaning base material which is frequently used and which is hard to be frayed even when a hole is formed and hard to enlarge the hole.

[0006]

SUMMARY OF THE INVENTION] The present invention is "(claim 1) single yarn fineness 8-100 deniers, made the total denier 8-500 denier synthetic fibers, a 3 bar or more warp knitted to have a loop-forming tissue 0.5 to 10 with respect to the weight of the base cloth
Weight percent of water-soluble hard-finished resin adheres to improve air permeability
A cleaning substrate that is resistant to contamination, which has a viscosity of 130 to 500 cc / sec / cm ² .

(Claim 2) The cleaning substrate according to claim 1, wherein the synthetic fiber is a nylon fiber. ".

Here, the synthetic fibers include, for example, polyester fibers, polyamide fibers, aramid fibers, polyvinyl alcohol fibers, polypropylene fibers, polyethylene fibers, glass fibers and the like. Any filament fibers may be used, but nylon fibers are particularly preferable. These fibers may be used as a mixture. The filament fibers are multifilament or monofilament and multifilament.

The cleaning substrate of the present invention has the following constitution.
It is necessary to The single yarn fineness is 8 to 100 denier. More preferably, it is 8 to 80 denier. If the single-filament fineness is less than 8 denier, dirt and the like accumulate between the single yarns and it is difficult to fall off. If it exceeds 100 denier, the loop-forming structure becomes less tight and becomes too hard during warp knitting of the base fabric.

[0010] The total fineness is from 8 to 500 denier.

The base fabric is a warp knit. In the woven fabric, when the base fabric is scratched, the thread is frayed and the hole is enlarged, making it unusable for use. By forming a loop-forming structure by warp knitting and forming a warp knit of 3 bars or more, the tissue points are fixed and uniform voids are formed.

The air permeability of the substrate is 130 to 500 cc / sec.
c / cm ² . The air permeability of the substrate is adjusted by improving the tightness of the yarn during warp knitting. Base material with air permeability of 1
If it is less than 30 cc / sec / cm ² , the flow of gas or liquid is reduced, and it is easy to become dirty. If the air permeability of the base material exceeds 500 cc / sec / cm ² , the eyes are too large, so that when the base material is sewn, skipping occurs, or the joint of the knitted structure is loosened, resulting in poor stability of the structure. Nylon fibers are particularly preferred in terms of resistance to soiling. The nylon fibers may be nylon 6 fibers, nylon 66 fibers or other nylon fibers.

The water-soluble hard finish resin of 0.5 to 10% by weight based on the weight of the base cloth is adhered to the base cloth to form a base.
When sewing materials , the sewability is greatly improved. The dyeing fastness is improved by dyeing the base fabric and then adhering a water-soluble hard finishing resin to the base fabric.

The value of the air permeability is determined by adding a water-soluble hardened
Means the air permeability of the base material after the resin
It is.

[0015]

The cleaning substrate of the present invention has the following effects.

(1) The cleaning substrate of the present invention is less likely to cause dirt. Dirt can be easily removed by washing . It is possible to wash in a short period of time because the dirt is likely to fall by the washing濯. Good drying.

[0017] (2) Kiyoshi掃用instrument can be a good sewing dimensional stability when sewing (mop), and the sewing efficiency.

(3) Cleaning using the cleaning substrate of the present invention
The tool does not expand even if a hole is made and the number of times of use increases.

[0019]

The present invention will be described below in detail with reference to examples. The measurement of each characteristic is as follows. Breathability (cc / sec / cm ² ): JIS-L-1076 Fragile method Strong (kg / 3cm): JIS-L-1076 Cut strip method

[0020] [Example 1] 210 denier 15 filament nylon 6 fiber (B
210/15) and 50 denier 1 filament (B5
With nylon fibers 0/1), at 3 bar tricot knitting machine, 24G, back (B50 / 1) 00 · 66 , middle (B210 / 15) 10 · 12 · 23 · 21, the front (B 210/15) 32 ・ 21 ・ 10 ・ 12 、 Course 4
The knitting conditions were 6 / inch. The resulting knitted fabric is scoured, set and dyed, and then a water-soluble hard finish resin (manufactured by Yoyo Chemical Co., Ltd., Pluscoat Z-446, 25% aqueous solution) is adhered and dried at a pickup rate of 80% to obtain a base fabric. . The air permeability of the base fabric is 130 cc / sec / cm ² , and the strength is 50 kg / 3 cm in the vertical direction and 120 kg in the horizontal direction.
/ 3 cm. When the obtained base cloth was used as a mop base cloth, the soiled state was repeatedly used for washing 30 times. The dirt was completely removed and the dimensional stability was good. No holes were made in the base fabric. At the 30th time, a hole of 5 mm was intentionally opened with a knife and washed, but no enlargement of the hole was observed. Repair was possible without enlargement even if a hole was made.

[ Comparative Example 1] A warp density of 38 yarns / inch and a weft density of 25 using 20/2 cotton yarn
It was woven in a plain weave at a rate of book / inch, scoured and heat-treated to obtain a cotton canvas. The breathability of the obtained cotton canvas is 30 cc / sec / cm
^{2. The} strength is 45kg / 3cm in the vertical direction and 3 in the horizontal direction.
It was 6 kg / 3 cm. The resulting Toko filtration using a cotton canvas as a mop for the base fabric, there is no problem in the function surface of the dirt is severely practical base fabric at the time of the washing was repeated 10 times was reduced commercial value. In addition, the perforated thread was frayed after repeated use 20 times, and the hole was enlarged and became unusable.
