Description
Technical field
The present invention relates to a kind of fabric.Be specifically related to the dust-proof fabric that can dye under a kind of normal temperature and pressure.
Background technology
Along with the fast development of economic society, industrial clean rooms and bio clean room be applied to semiconductor, optical instrument, precision electronic device and particular procedure ward, food more and more widely, brewage etc. requires the industry of clean working environment.The clothing of physical activity and dress is dust source important in the toilet.Can prevent effectively that the dust in human secretion and the underwear from discharging to environment though have the fabric of good anti-dust performance, can prevent simultaneously the dust that clothing absorption is outside and itself not produce Soft flocks, thereby guarantee the cleanliness factor of working environment, but present existing dust-proof fabric all needs the processing of at high temperature dyeing, and technology is than complexity and cost height; Or only emphasize anti-dust performance and sacrificed frivolous property, gas permeability, poisture-penetrability and the feel of lining.
For dyeing at normal temperatures and pressures, simultaneously can guarantee low powder amount again, improve wearing comfortableness, relevant issues such as reduce production costs have been carried out some relevant investigation.Disclose the dust-proof fabric (comprising manufacture method) that uses in a kind of semiconductor clean room among the Chinese patent CN98103438.1, it is made of knitwear internal layer, high-hygroscopicity polyurethane formic acid esters resin molding intermediate layer and the polyester of high density textiles skin that inweaves conductive filament.Though the anti-dust performance of gained dust-proof fabric and performance comfortable and easy to wear make moderate progress.But it remains and adopts conventional high-temperature pressure dyeing technology, the production cost height, and the processing technology complexity lacks frivolous property simultaneously and causes wearer's operation inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of low dust-proof fabric that can dye at normal temperatures and pressures of sending out dirt, high dust catching efficiency, high-antistatic and high-air-permeability that has.
Technical solution of the present invention is:
The dust-proof fabric that normal temperature and pressure of the present invention can dye down is by containing the 2-methyl isophthalic acid, and non-the dirt copolyesters long fiber and the Fei Fa dirt conductive fiber of ammediol structure constitute, and the tightness of this dust-proof fabric is 2000～4000.
Polyester in this dust-proof fabric in the copolyesters long fiber of non-dirt contains the 2-methyl isophthalic acid, the ammediol structure.Here contain the 2-methyl isophthalic acid, the polyester of ammediol structure is meant and is the polyester that the aliphatic dihydroxy alcohol monomer copolymerization below 6 forms with side chain and carbon number.
Constitute this and contain the 2-methyl isophthalic acid, the content of the terminal carboxyl group COOH of the polyester in the copolyesters of the ammediol structure processing silk is 25 equivalents/below the ton.The content of terminal carboxyl group can make the heat resistance of copolyesters reduce during greater than 25 equivalents/ton; Preferred 20 equivalents/below the ton.The content of diethylene glycol (DEG) is below the 2.0wt% in the polyester, and this moment, the heat resistance of copolymer was very good.Diethylene glycol (DEG) is that secondary giving birth to forms and exist with the form of closing with polyethylene terephthalate copolymer when polyester is synthetic, when the content of diethylene glycol (DEG) surpasses 2.0wt%, the temperature of the fusing point of polyester or beginning fusion is low during spinning, can cause that heat resistance descends, degradation problem under the feel of the finished product that is made into by this fiber.Preferred diethylene glycol (DEG) content is below the 1.5wt%.When carrying out polymerisation rapidly, also to keep the high-fire resistance of polyester, so phosphorus atoms content P in the polyester of the present invention and metallic atom content M satisfy formula (1) and formula (2):

The conductive fiber of non-dirt is selected metal fibre, charcoal cellulose/polymer composite fibre (composite fibre of charcoal element and polymer) or conducting polymer fibres for use in the dust-proof fabric of the present invention.In order to overcome blackstreak or the grid in the dust-proof fabric, preferred white conducting polymer fibres.Conductive fiber is strip or trellis and distributes in dust-proof fabric, and distribute spacing is 2～10mm, considers production cost and makes dust-proof fabric have higher antistatic property, the preferred 4～6mm of distribute spacing.The long stapled cross sectional shape of copolyesters can be circular or special-shaped in the fabric of the present invention, and the odd-shaped cross section shape here can be odd-shaped cross sections such as pancake, triangle, " ten " font, pentagon or other irregular polygon.
Can be full-drawn yarn or false twist yarn as dust-proof fabric of the present invention through the copolyesters long fiber yarn of weft yarn, the filament radical of yarn is 24～144, consider the comfortableness and the dustproof effect that improve fabric, preferred 36～96 of the filament radical of yarn, more preferably 48～72.The fineness of this yarn is 50～150D, and the twist is 0～400T/m.
The present invention is compound conductive yarn with non-dirt conductive fiber and common yarn Compound Machining preferably, weaves again.
Making dust-proof fabric of the present invention have good dustproof effect, and reduce the floating long and raising Density of warp thread, is the structure of main weave with plain weave or twill preferably.For the dustproof effect that improves dust-proof fabric and have better snugness of fit, the warp-wise density of fabric of the present invention is 80～250/inch, and latitudinal density is 60～140/inch.
The dyeing and finishing processing of dust-proof fabric of the present invention mainly comprises: concise, preceding drying, middle typing, dyeing, dry, the back arrangement typing in back.Processing technology of the present invention is simple, engineering is few, can reduce the pollution of dust-proof fabric in process.Make dust-proof fabric waterproof and oilproof performance and high dust catching efficiency also can carry out resin, calendering processing.The used copolyester fiber of the present invention can adopt disperse dyeing at normal temperatures and pressures, and dyeing temperature is 90～100 ℃, and oligomer is difficult for stripping, effectively reduces the powder amount 10～90% of dust-proof fabric.The present invention adopts the dyeing of normal temperature and pressure, and dyeing time is short, does not need pressurization to heat up, and has reduced production cost effectively.
The dust catching efficiency of gained dust-proof fabric of the present invention is 65～95%, and powder amount is 80～500/2m
