Abstract

The invention relates to alcohol and water repellent non-woven fabrics made from synthetic polymer fibers. The fibers comprise a surface modifier admixed with the synthetic polymer to impart alcohol and water repellency properties.

Description

The supatex fabric of alcohol and water repellent
Background of invention
The present invention relates to the alcohol and water repellent supatex fabric made by the synthetic polymeric fibers that mixes with surface modifier.
The purposes of supatex fabric is various, comprises as hospital apparel, and for example surgery is used with coverlet, surgery with cap, surgery and hidden clothes, surgery work clothes, and curtain.Supatex fabric also can be used in the filter,, is used for filter particulates and aerosol (aerosol) pollutant, for example face shield, water filter and air cleaner that is.
Multiple fluorine-containing chemical (fluorochemicals) has been used to make various substrates to possess water proofing property, grease proofness and soil pollution resistance.The most normal employing topical application of these fluorine-containing chemicals (for example, by spraying, filler, or (finish bath immersion) soaked in the finished product bath).Formed supporting prevents that the property substrate has obtained extensive use in the field of paying attention to waterproof and/or grease proofing (and soil anti-soil) characteristic, for example be used for the protective garment that medical technician and laboratory workman wear, expect that here it can prevent blood, blood-borne pathogens, and other body fluid passes fabric (that is, blocking-up and chemical toxicity or infectious substance contacts).For the great majority of these application, expect that also it has antistatic property.
Static charge buildup is in the processing of many industrial products and material and the reason that various problems produces in using.Electrostatic charge may cause material to stick together or repel mutually.This is the problem in the processing of fiber and textile especially.In addition, static charge buildup may cause object attract dirt and dust, thereby reduces the effectiveness that fluorine-containing chemical supports anti-agent (fiuorochemicalrepellent).Static release from insulating bodies also may bring serious danger.For example, in the presence of flammable materials, for example, under surgical environments, static discharges may become burning things which may cause a fire disaster, causes and catches fire and/or explode.Static is the problem in the electronics industry especially, because modern electronics very easily discharges by permanent damages because of static.
Traditional antistatic additive (wherein major part is a wetting agent, and electric-charge-dissipating is carried out in its absorption and conduction that relies on water) be not very effective with fluorine-containing chemical when anti-agent is used in combination usually.The result of this combination greatly disappear when causing antistatic property usually or supporting anti-characteristic (perhaps both) (and even elimination) with respect to the arbitrary additive of independent use.
In addition, traditional antistatic additive and fluorine-containing chemical are combined in the polymer melt processed and applied to anti-agent, this point is difficulty very, because for example, the water relevant with the wetting agent antistatic additive can evaporate rapidly under the melt processing temperature.This just causes forming undesirable bubble in polymer, and causes extrusion equipment screw slippage to occur.Many antistatic additive also lack essential heat endurance, cause producing bad smell (for example, in melting and spraying application, use high extrusion temperature).
Therefore, still need the fabric of alcohol and water repellent, expect that it can also make substrate possess good antistatic property and characteristic is prevented in good supporting, particularly can be used as melt additive, and can not cause processing problems or metal defects.
