The invention discloses blended fabric of polyetherimide and flame-retardant viscose. The blended fabric is formed by blending of 20-30 parts by weight of polyetherimide fiber and 70-80 parts by weight of flame-retardant viscose fiber. The blended fabric of the polyetherimide and the flame-retardant viscose has high flame-retardant performance, is comfortable to wear and low in cost, and can be applied to protection products.
Description
Technical field
The present invention relates to a kind of fabric, relate in particular to the BLENDED FABRIC of a kind of PEI and anti-flaming viscose.
Background technology
Polyether-imide fiber, English name: polyetherimide fiber, be called for short: the PEI fiber is a kind of synthetic fiber that are spun into by linear PEI one base polymer.Aryl ether group directly links to each other with the phenyl ring of fragrant imide, the base polymer of repetitive take ether and imide as the architectural feature group.Usually be polymerized through nucleophilic displacement of fluorine by fragrant diphenol and dinitro double imide monomer.
PEI has the chemical resistance of wide range, comprises anti-most hydrocarbon, alcohols and all halogenated solvents; But the also anti-weak base of inorganic acid resistance and short-term.To partially halogenated solvent, PEI is good selection.Its hydrolytic stability is fine, soaks 10000 hours after-drawing Strength retentions more than 85% in boiling water, and under the 270F temperature, 2000 after-drawing Strength retentions of steam hot press cycle are 100%.PEI has good uvioresistant, gamma ray performance, processes under the cobalt x radiation x of 400 Megarads, and TENSILE STRENGTH keeps 94%.
The long-term serviceability temperature of American insurance merchant laboratory regulation polyimide resin is that 338T and 356T(are according to grade), the burning grade reaches UL94V-0(10 mil thickness.) oxygen index (OI) reaches 47, PEI meets FAA anti-flammability that the aircraft internals require and the material standard of rare the putting property of heat.Its glass transition temperature is 419F, and allows to be interrupted use under 392F, under higher temperature, produces the short-term skew.Under 356T, draft temperature and flexural modulus are respectively 41 with more than the 2068MPa.Near under the glass transition temperature, have higher strength and stiffness with glass, carbon fiber reinforced material.
PEI allows it to replace metal and other material in many structural devices in the Long-term Anti creep properties under high temperature and the stress.Under variable temperature, moisture and frequency condition, show good electrical property.Low loss factor under the GHz frequency makes PEI have high wearing property of microwave.Its ion-type pollutant low water-mark, the conductance after 120 hours waters extract under 250F100%RH and the 207kPa, more than 20 megaohms, it can be used as the insulating materials of electronic sensor element.
Summary of the invention
