Description

Wiping member and Cleaning preparations

Technical background

The present invention relates to Wiping member.Particularly, the present invention relates to be used to wash or the Wiping member of polished surface.

The product that comprises Wiping member is known product, and described Wiping member makes by the flat yams of plastic foil preparation or by the metallic flat yarn of metal plastic film preparation by knitting or braiding.Can be sack with these formed product, be packaged with polyurethane sponge or analog in the bag.This class Cleaning preparations is in the function admirable of removing aspect huge (bulky) solid dirt, because have the membrane portions of many bendings in their the looped fabric surface, when these sweeps ran into dirt under some angle, described goods can scrape off or wipe dirt owing to the shape and the hardness of film.

Yet, do not have sufficient contact area between this class Wiping articles and the object surfaces to be cleaned, so they can not remove the dirt of sparse distribution on body surface to be cleaned very effectively, as oil film.On the other hand, also known many Wiping articles wherein use acrylic fiber or superfine fibre with abnormity (heteromorphous) cross section to remove oil film etc., and need not to use washing agent.When these fibers of independent use, show for dirt such as oil film to have the effect of height, but problem is impossible wipe effectively huge solid dirt as burning mud or soap mud.

The Japanese Utility Model communique of registration discloses a kind of scouring rag for No. 3037459, it is as the Wiping member that comprises the combination of plastic foil and yarn such as acrylic acid yarn, this scouring rag makes by knitting spinning acrylic acid yarn, and spiral has twined the flat yams that is prepared by metallized plastic foil around this spinning acrylic acid yarn.Yet such structure can not be brought into play enough effects of being wiped dirt by film, because the film that is wound is parallel to spinning acrylic acid yarn, has therefore stoped this film to run into dirt with effective angle.

As analogous cases, Wiping member also is commercially available, it comprises sack and is encapsulated in a sponge core in the bag, the looped fabric that will form by spinning polypropylene yarn and spinning acryloyl (acryl) yarn and replace by the flat yams that polyester film is made knitted together forming bar, thereby make this sack.Yet in the looped fabric of this structure, polyester film is linear and unbalanced distribution.Therefore, because it removes the anisotropy ability and the poor efficiency of wiping dirt of dirt, it is inconvenient.

Detailed Description Of The Invention

Looped fabric is to use yarn series at first, and each encircles to form the plane by vertical or horizontal interlocking, thus the cloth of making. The structure of looped fabric is made of a series of rings. Therefore, when looped fabric was made up of such as the flat yams made from plastic foil the anisotropic yarn of bending, the sweep of ring will stretch out from the cloth surface with almost fixing angle (direction), and will arrange regularly.

When these looped fabrics of preparation, when partly replacing the flat yams made by plastic foil with silvalin such as the wet-spun yarn of being made by acrylic fiber and when equably knitting, plastics zona and acrylic fiber ring arrange regularly, and for example coil suffers that coil ground (stitch by stitch) is alternately arranged or every two or more coil is alternately arranged. This will be so that the plastics zona evenly and regularly be arranged on the whole surface of gained looped fabric, and the acrylic fiber ring will be arranged in identical systematicness between the plastics zona.

In the time will being formed ring as mentioned above by the flat yams that plastic foil is made, the front end of sweep can stretch out from the cloth surface.Therefore, by knitting flat yams of being made by plastic foil and the spinning through the part wet spinning (spun yarn) of being made by acrylic fiber prepare looped fabric equably, have a plurality of plastic foil sweeps in this looped fabric surface, they are all even to be arranged on the whole surface of cloth regularly.The front end of sweep will stretch out from the cloth surface with almost fixing angle.

" knitting equably " is meant by equally using two or more yarns to prepare on the whole looped fabric uniformly.Preferably use yarn with amount (length) much at one.As long as Wiping member of the present invention has the aforementioned arrangement of the flat yams sweep of being made by plastic foil, this Wiping member just can also comprise and plastic foil flat yams and even yarn or the fiber knitted together of wet-spun yarn made by acrylic fiber.

Yet for example, the looped fabric that the looped fabric that is prepared by knitting dissimilar yarn respectively by entwine (interknitting) makes is uneven in whole cloth, and it does not meet even looped fabric of the present invention.

Knitting type to looped fabric is not specifically limited, as long as it is the knitting type that is generally used for Wiping member, this Wiping member is used to wash or polish tableware in kitchen or the analog, pan etc.Preferred knitting type is to make to form opening portion between the sweep of the flat yams of being made by plastic foil and looped fabric surface.Between the dirt that exists opening portion to make flat yams be easy to enter object to be cleaned and adhere on it, therefore, be easy to separate them.In addition, might be at the many dirts that separated of opening IT.Therefore, such looped fabric can keep its good scouring performance.

Usually, the knitting type of looped fabric is not specifically limited, as long as it is made of a series of rings.Yet height spaces may not have the opening portion of sufficient size in the loop section of (gauge) looped fabric.Along with loop density increases, the direction of stretching out of film is understood near being parallel to surface to be cleaned and looped fabric, more be difficult to obtain wiping effect thereby become.On the other hand, when spacing looped fabric, tend to allow exotic to enter it, thereby produce operational failure and hygienic issues so that the sack form use that wherein comprises foam member is low.Although depend on the thickness of stand-by yarn, for example when using the bifilar acrylic acid yarn at 30 to 60 dawn, in the square of each 10-cm length of side, the number of coil is generally about 20 coil * 20 and walks to 100 coils * 70 row, and more preferably from about 65 coils * 50 row are walked in 30 coil * 30.

For flat yams, used thickness is that 30 to 45 μ m, width are 0.7 to 0.85mm plastic foil usually, because can realize scraping off or wiping the operation of huge solid dirt by the rigidity of film.As plastic film material, use polypropylene, polyester, polystyrene etc.In order to give design character etc., also allow to use the metallic flat yarn made by types of metallized plastic films or other multilayer film (film that for example, comprises the plastic layer that accompanies metal level) as flat yams.

For forming spinning, use the wet spinning acrylic fiber, because acrylic fiber can easily be removed oily dirt, and spinning can guarantee the abundant contact area with surface to be cleaned.Be formed in the spinning by the superfine fibre that will have profiled cross-section, also allow to use described superfine fibre.

Wiping member of the present invention can use separately, as the wiper or the Cleaning preparations of tableware such as plate etc.When described Wiping member is formed as sack, when encapsulating foam member such as polyurethane sponge or analog then, perhaps when being applied to foam member, it can also be as the Cleaning preparations of tableware such as plate etc.

Described Wiping member has enough washabilities for the dirt of huge dirt and similar oil film, because the knitting or woven composition of the yarn that it is made by the flat yams made from plastic foil with fiber such as acryloyl is formed, described flat yams can be wiped huge dirt effectively, the described yarn made from fiber can be brought into play the washability to dirt such as oil film, has only when Cleaning preparations and just can wipe oil film when surface to be cleaned contacts closely securely.In addition, because in looped fabric or woven cloth, the flat yams of rigidity plastics film contacts with surface to be cleaned at an angle, so used power will concentrate on limited dirt part in the wiping process, thereby can easily produce starting point to peel off dirt from surface to be cleaned.

The following example further specifies the present invention.Yet they should not be construed as and limit the invention to its details.

Although this paper has shown and described specific embodiments of the present invention, understand these embodiments the many possible concrete layout that can design when using the principle of the invention only is described.According to these principles, under the situation that does not deviate from the spirit and scope of the present invention, those of ordinary skills can design other many with different layouts.Therefore, scope of the present invention should not be limited to the described structure of the application, and is only limited by the equivalent of the described structure of the literal of claims and those structures.
