Description

Clean-room cleaning cloth
Technical field
The present invention relates to clean-room cleaning cloth, it is to be 30 to 300g/m by weight per unit area 2A kind of microfilament non-woven material form.
Background technology
Clean rooms is being produced, and obtains constantly using widely in chemical examination and the management sophisticated product, and wherein importantly, various procedure of processings will be carried out in the egranulose environment of a kind of strictness.In high-tech product, as microelectronic circuit, optics or medicine product, the improvement of producing constantly proposes higher requirement to the granule content of clean rooms, special example, grade is that 100 clean rooms require at every cubic feet of space air, the particulate of size 〉=0.5 μ m is in the highest 100 scope, or at the metric system clean rooms grade M3.54 of equivalent, requirement is at every cubic metre space air, no more than 3530 of the particulate of size 〉=0.5 μ m [per 1,000,000 (1,000,000/-ppm) or the particle that increases per 1,000,000,000 (part per trillion-ppb)].Integrated circuit will generate on the promptly very thin silicon single crystal flake on so-called " silicon chip ".Integrated circuit requires triode and other electronic device that accurate electrical connection is arranged each other.Each circuit devcie is to be connected by a kind of conducting film of being made up of plated metal.In this rete, produce the printed conductor structure by a kind of photoetching process.Below semiconductor element and the position that only allows setting of the insulating barrier between the metal film of deposition on electrical connection is arranged.On the surface of " silicon chip ", be coated with insulating layer coating, make each device afterwards, but use deposition of conductive metals " silicon chip " before to make the printed conductor structure.Pollute, can cause short circuit between the device, and make the circuit function partial failure of setting thus at least as the disconnected fragment of fiber or dust particle.So the basic demand at this is that all surface and workpiece are not polluted as much as possible.
From file US4,888,229 and US 5,229,181 people be familiar with braiding or knitting clean textile, by special their edge of edging rolling, prevented that fine, soft fur from exposing and the disconnected fragment of fiber.In addition from file US4, people have been familiar with the clean-room cleaning cloth be made up of non-woven material in 328,279 and 5,736,469.In order to reduce the amount of ions that can extract or to prevent the static load, apply a kind of immersion coating at the fiber surface that forms non-woven material.File US5,320,900 and US5,645,916 have described a kind of clean-room cleaning cloth, and it is made up of fibre blend, reinforces by the water jet treatment non-woven material.Fiber employing synthetic fiber such as polyester and cellulose-or regenerated celulose fibre.The shortcoming of the clean-room cleaning cloth that these are familiar with is, can not stand washing process, yet do not have washing process can not reach the highest clean rooms grade 10 or grade preferably.So this grade only is used for braiding or knitting continuous filament yarn at present.
Summary of the invention
Task of the present invention is to provide inexpensive, rinsable clean-room cleaning cloth, and it satisfies the requirement of clean rooms grade 100, and the method for producing clean textile.By following clean rooms washing process,, can be applied in clean rooms grade 10 or more high-grade based on the clean-room cleaning cloth on the microfilament spun-bonded type non-woven material basis according to of the present invention.
According to the present invention, to finish the work with clean-room cleaning cloth, clean-room cleaning cloth is to be 30 to 300g/m by weight per unit area 2A kind of microfilament non-woven material form, described non-woven material is by melt-spun, pneumatic stretching and directly to be paved into fibroreticulate fiber number be that 1.5 to 5dtex multicomponent continuous filament yarn is formed, at least 80% multicomponent continuous filament yarn is split into fiber number to be 0.1 to 1.0dtex fine continuous filament yarn and to reinforce.This clean-room cleaning cloth has a kind of surface texture, and dust particle and liquid well penetrate in the surface texture, and stick to wherein.In addition, owing to form, in clean-room cleaning cloth, have only fiber seldom to break end by continuous filament yarn.Do not contain fine, soft fur in the clean textile, the edge of clean textile also needn't turn down and sew on or fringing.
Preferred clean-room cleaning cloth is such, described non-woven material is by melt-spun, pneumatic stretching also directly is paved into fibroreticulate multicomponent continuous filament yarn composition, its fiber number is 2-3dtex, and at least 80% multicomponent continuous filament yarn is split into fine continuous filament yarn and reinforcing that fiber number is 0.1-0.3dtex.
Preferred clean-room cleaning cloth is such, the bi-component continuous filament yarn that its multicomponent continuous filament yarn is made up of two kinds of polymer incompatible with each other, particularly a kind of polyester and a kind of polyamide.But such bi-component-continuous filament yarn has good fissility to the ultra micro continuous filament yarn, causes the ratio of a rational strength and weight per unit area.
Preferred clean-room cleaning cloth is such, and its multicomponent continuous filament yarn has the tangerine flap or is referred to as the cross section of the multi-disc segment structure of " patty ", and wherein fragment alternately contains a kind of in two kinds of incompatible polymers.Except the multicomponent continuous filament yarn of this tangerine flap multi-disc segment structure, incompatible polymers also may be the arrangement of (s/s) side by side in the multicomponent continuous filament yarn, and this helps producing crimp filament.This arrangement of incompatible polymers in the multicomponent continuous filament yarn confirms it is that good fissility is arranged.
Preferred clean-room cleaning cloth is such, at least one that forms in the incompatible polymers of multicomponent continuous filament yarn contains a kind of additive, as pigment, the antistatic additive of permanent action and/or influence the additives of hydrophilic or hydrophobic performance, maximum is to satisfy the requirement that allows the extractibility value in water and isopropyl alcohol.The clean-room cleaning cloth of being made up of the long filament of dope dyeing has extraordinary wash stability.In addition, can reduce or prevent static, improve the moisture transmission performance by additives.
The technology of producing clean-room cleaning cloth according to the present invention is, the multicomponent continuous filament yarn is by melt spinning, pneumatic stretching, and directly be paved into a kind of fiber web, reinforce in advance in case of necessity, non-woven material is reinforced with the high-pressure fluid jet, splits into fine continuous filament yarn simultaneously, its fiber number is 0.1 to 1.0dtex, and preferably fiber number is 0.1 to 0.3dtex.The clean-room cleaning cloth density of Huo Deing is very even like this, and Fiber Distribution is even, does not have the layering tendency, shows high modulus value.
Produce clean-room cleaning cloth and preferably undertaken by following method, by carrying out repeatedly with high-pressure water jet each face to non-woven material, impact at least once makes the multicomponent continuous filament yarn reinforce and divide.Make clean-room cleaning cloth have good surface thus, organize continuous filament yarn has more＞80% division degree.In addition, clean-room cleaning cloth according to the present invention is with good ratio water imbibition and low drying time and famous.
According to the present invention, clean-room cleaning cloth can repeatedly use as smearing wiping cloth (rags).
The advantage of clean-room cleaning cloth is to satisfy the requirement of industry clean rooms lauderability, can clean rooms grade 10 or more high-grade on be applied.
The specific embodiment
