Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a stretch loop pile cloth having excellent antibacterial properties, which is excellent in water absorption and has excellent washing durability, and is preferably used for general households, hospitals, sports, and consumer products. Loop pile fabric and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, as pile fabrics for household or hospital use, for example, pile fabrics such as bedspreads and bed spreads have natural or regenerated fibers such as cotton, hemp, and rayon or 1 dTex or more in a loop pile portion. Synthetic fibers such as polyester, polyamide, and polyacrylic having a thickness are used. Fabrics made of these loop piles lack the stretchability, and thus it takes time to make a bed. Since the fibers were thick, the skin had a rough and hard feeling, and had no antibacterial property, which was insufficient in terms of hygiene.

Examples of pile fabrics for sports include grip tapes for tennis and badminton,
It is suitable for use in glupe tapes such as goriffs, mascot covers, wristbands used during jogging, hair bands, etc., but in any application, the fiber thickness of the loop pile part is thick, so the surface is rough and hard, Since the skin has a rough feeling and does not have elasticity, it does not fit to irregularly shaped materials. Further, when sweating during exercise, water absorption is insufficient, which causes discomfort and has no antibacterial property, which is a problem in hygiene.

As the pile cloth for consumer goods, there are, for example, a paint roller and a wiper. In the case of the paint roller, a brush-shaped cloth is usually wound around the roller, or a tape-shaped pile cloth is wound around the roller. . When the paint is applied to the wall surface by using these paint rollers, especially when trying to apply a paint having an extremely low viscosity, liquid dripping occurs and it is difficult to apply the paint uniformly on the applied surface. Further, there was a problem in hygiene due to the generation of mold after repeated use. Further, for example, a wiper lacks stretchability and antibacterial property, so that it does not fit to an irregularly shaped material, and there is a problem in hygiene in repeated use.

Further, as pile fabrics and a method for manufacturing the pile fabrics, Japanese Utility Model Publication No. 52-158176 and Japanese Utility Model Publication No. 53-3 are used.
No. 6977, No. 54-69964, No. 52-115374, No. 51-4563, No. 49-144973, No. 53-43.
Japanese Patent No. 46853, Japanese Utility Model Publication No. 52-33428, Japanese Patent Application Laid-Open No. 53-122865 and the like are proposed.

All of these are intended to improve the performance as a "dust-cleaning towel" in which the dynamic frictional force with the human body is increased by using the surface as an uneven structure and using it as a bath towel. Since it has no property, it is preferable as "for scrubbing towel", but it is not preferable for the above-mentioned applications requiring stretchability such as the present invention. Further, the antibacterial property has not been examined, and it is not preferable in terms of hygiene in repeated use.

Further, Japanese Patent No. 2697151 proposes a towel cloth using an ultrafine pile. This patent is intended for bathing and wiping,
As a "cleaning towel", the pile fineness is thin, the soft touch to the skin is improved, and it is also excellent for wiping, but it is not preferable in the above-mentioned applications requiring elasticity. Further, it was unsanitary because it had no antibacterial property after repeated use.

Further, Japanese Patent Publication No. 61-10588,
Japanese Examined Patent Publication (Kokoku) No. 61-52257 proposes a pile knitted fabric using ultrafine yarn of 0.6 denier or less. However, these are designed for cold weather clothing such as artificial fur made of cut pile, and the performances that are inevitably obtained are different.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION The inventors of the present invention firstly reasonably selected an amorphous base material for a material suitable as a loop pile cloth for daily use for general households, hospitals, sports, and consumer goods. As a result of diligent studies, it has a good fit, the surface of the fitted base material has a gentle feel to the skin, is excellent in water retention, wiping property and antibacterial property, and is durable in these performances. ,
A fabric such as a knitted woven fabric in which a sea-island type composite fiber or split fiber type composite fiber filament yarn made of polyamide fiber and / or polyester fiber is used for the loop pile part, and stretchable synthetic fiber is mixed for the base yarn part. It was found that the above problems can be solved all at once by using the above-mentioned product and dividing it by a specific dividing method and then adding a specific antibacterial agent.

The stretch loop pile fabric of the present invention is a fabric such as a knitted fabric having a loop pile yarn structure, and the loop pile length is 0.3 to 10 m from the base portion.
m, and in the loop pile yarn and / or the ground yarn, 50 to 9 ultra fine synthetic fibers of 0.5 dTex to 0.0001 dTex to at least the entire loop pile fabric.
A stretch loop pile fabric comprising 5% by weight or more and having elastic synthetic fibers in the ground yarn.

The ultra-fine pile material that constitutes the pile fabric is
A polyamide-based and / or polyester-based synthetic fiber filament fiber, which is a sea-island type composite fiber or a release type composite fiber composed of two or three components, can be obtained by elution treatment or release treatment.

As the polyamide fiber, nylon 6,
Nylon 66, nylon 4, nylon 11 and the like, and modified products thereof may be mentioned. Any fiber can be used, but nylon 6 is preferably used.

Examples of the polyester fibers include polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, and modified products thereof. Any fiber can be used,
Polyethylene terephthalate is preferred.

The sea-island type composite fiber and the peeling type composite fiber can be used after being subjected to known Woolly processing, bunron processing and the like.

The stretch pile pile fabric of the present invention has a loop pile length of 0.3 to 10 mm from the base, preferably 0.4 to 9 mm, and more preferably 0.5 to 8 mm. If it is less than 0.3 mm, the pile length is short, so that the voids between the loops are small and the water absorption is insufficient. For example, with grip tape,
Comfort cannot be obtained, and the content of the low-viscosity paint is insufficient in a paint roller or the like, and uniform application cannot be achieved. On the other hand, when it exceeds 10 mm, the loop is settled and voids are filled, so that the comfort and the uniform application function cannot be obtained as in the above case. Furthermore, the thickness of the ultrafine synthetic fiber loop pile is 0.5 dTex to 0.00.
01 dTex, preferably 0.4 dTex to 0.
001 dTex, more preferably 0.3 dTex-
It is 0.01 dTex. If it exceeds 0.5 dTex, it is too thick, so that it feels like a conventional loop pile, the surface touch is rough and hard, and a touch gentle to the skin cannot be obtained. On the other hand, when it is less than 0.0001 dTex, since it is too thin, it clings to the skin and causes discomfort to the skin, which is not preferable. Next, the mixing ratio of the ultrafine fibers is 50 to 50 with respect to the entire loop pile fabric constituting the loop pile.
It is 95% by weight. A preferable mixing ratio is 55 to 90% by weight,
More preferably, it is 60 to 85% by weight. If it exceeds 95%, the pile fabric cannot be formed because the number of constituent yarns is insufficient. On the other hand, if it is less than 50%, a soft touch to the skin and sufficient water retention cannot be obtained.

Further, the stretch pile fabric of the present invention comprises elastic synthetic fibers in the ground yarn. The mixing ratio is
It is not particularly limited and may be appropriately selected depending on the purpose and application.
For example, for bed covers, paint rollers, cleaning wipers (like mops), it is sufficient to choose a stretchable mixture ratio that is easy to wear, and for wrist bands, hair bands, etc., tightening is too strong and uncomfortable. You can choose a mixture ratio that does not become. As the elastic synthetic fiber, any material can be used as long as it is a synthetic fiber having elasticity, and for example, various synthetic fibers are processed, for example,
Woolie-processed yarn, knit-denit-processed yarn, banglon-processed yarn, synthetic rubber, semi-synthetic rubber, polyurethane fiber and the like can be used, but polyurethane-based synthetic fiber used for socks and the like can be preferably used.

As the polyurethane-based synthetic fiber used in the present invention, known fibers can be used, but it is preferable that the elastic recovery rate at 200% elongation is 90% or more. If the elastic recovery rate during stretching is less than 90%, the knitted fabric may be stretched after repeated use. The polyurethane-based synthetic fibers may be used alone and / or aligned with or in combination with the elastic synthetic fibers described above.

The density and texture of the knitted fabric can be freely selected according to the purpose and application. For example, for bed covers and bed spreads, fabrics are preferable, and for example, wristbands, hair bands, paint rollers,
Knitting is preferable for the wiper and the like. The tissue can also be selected according to the purpose and use, and either double-sided loop pile or single-sided loop pile can be selected.

In the present invention, for example, the loop pile cloth used in general households or hospitals, or the wash durability such as loop pile cloth used for sports, paint rollers, and wipers, especially for industrial use It is possible to provide a wiping cloth having excellent washing durability and antibacterial properties. Fabrics with antibacterial properties have been variously studied in general clothing fabrics and the like, and the water washability at home has reached a considerable level.
No one has been found that exhibits sufficient durability under conditions in which a large number of industrial washings, usually 60 to 85 ° C., are repeated. In particular, the loop pile wiping cloth for hospitals requires repeated wiping / washing of dirt, and requires durability that cannot be imagined with cloths for general clothing. The present invention provides a product that exhibits sufficient durability even under conditions in which such industrial washing is repeated many times.

In order to impart such an antibacterial performance excellent in the durability against industrial washing, an antibacterial agent excellent in a specific exhaust capacity is used for the filament yarn, especially the polyester fiber. A pyridine type antibacterial agent is used as such an antibacterial agent. Among them, especially 2-pyridylthiol-1-oxide zinc has been found to have the property of being exhausted due to its dramatic durability, and in particular, to have excellent exhaustion ability for polyester fibers. . Such an antibacterial agent having a small average particle size is preferably used from the viewpoint of exhaustion property, specifically 2 μm or less, more preferably 1 μm or less.
Those having an average particle size of less than or equal to μm, particularly preferably less than or equal to 0.7 μm are used.

The antibacterial durability of the stretch loop pile fabric of the present invention is such that the MRSA value after industrial washing of 50 times is preferably 2.5 or more, more preferably 3.0 or more. I have. When the MRSA value is less than 2.5, sufficient antibacterial properties cannot be obtained, and even when the initial performance is 3.0 or more, if the MRSA value is less than 2.5 after washing, durable antibacterial properties are not obtained. It cannot be said to have it, is not practical, and is a problem in terms of antibacterial performance.

Further, the loop pile fabric of the present invention preferably has a water absorption rate of 1 second or less and a water retention amount of 200% by weight or more as characteristics relating to water absorption performance of absorbing sweat.
When the water absorption speed is 1 second or more, it is difficult for sweat or water to be taken into the inside, so that, for example, a bed cover, a grip tape, a wrist band, etc., always have a sticky feeling and cause discomfort. Also, the water retention capacity is 200% by weight
When it is below the range, for example, in a paint roller or the like, the liquid runs out immediately, and uniform coating cannot be performed. There is a problem with wipers that they do not hold liquid well and cannot be wiped clean.

Next, an example of the method for producing the loop pile fabric of the present invention will be described. First, as the composite fiber, prepare a multifilament yarn composed of a composite fiber such as a sea-island type, a separation split type and a special blend type that can be split afterwards.
The two are aligned and given a yarn length difference as necessary, or a yarn is processed into a composite yarn form. As means for forming a composite yarn, means such as drawing, twisting and entanglement can be used. The obtained composite yarn becomes the base and pile yarn of the loop pile fabric. The base becomes a base by itself or by covering with urethane synthetic fibers alone and / or elastic synthetic fibers.

Next, the composite yarn is used for knitting and weaving, and the obtained knitted fabric or the like is subjected to a division treatment to obtain a finely woven fabric. As the fineness-reducing treatment, there are means such as chemical peeling, physical peeling, and dissolution removal of one component. For example, when the peelable composite fiber is used, the fineness can be reduced by rubbing it while immersing it in a chemical, and when the sea-island composite fiber is used, the sea component can be dissolved and removed to reduce the fineness.

Next, the finely woven fabric is subjected to antibacterial processing simultaneously with dyeing or alone. Further, for example, when used as a wiper, the stretch loop cloth is attached to an amorphous base material, and it is used for window glass of general homes and hospitals, glass such as mirrors, around sinks in washrooms, bath tubs, and tables. It can be used for all kinds of materials, but it is especially suitable for wiping wet parts such as around sinks and baths.
