Abstract
The invention discloses an antistatic nylon textile. A coating resin layer is covered on the single-fiber surface of the textile, and the coating resin layer is formed by polyether type polyurethane resin and fluorine-based resin, which perform cross-linking reaction with a terminal group of nylon fiber. The initial friction-charged electrostatic potential of the textile is below 2000V, the water repellent degree is above grade 4, and the oil repellent degree is above grade 4; and the friction-charged electrostatic potential after 20 times of family washing is below 2500V, the water repellent degree is above grade 3, and the oil repellent degree is above grade 3. The antistatic nylon textile disclosed by the invention fills in the blank that the nylon textile can not integrate the antistatic performance and the water-repellent and oil-repellent performance simultaneously.
Description
Technical field
The present invention relates to a kind of nylon shioze fabric with antistatic property, be specifically related to a kind of have simultaneously antistatic, refuse the splendid nylon shioze fabric of water, oil repellent energy and washing resistance.
Background technology
The nylon shioze fabric has rub resistance, anti-flexural deformation, be difficult for producing after wrinkle, moisture absorption comparatively fast the performance such as drying, is widely used in the various fields such as dress material, carpet, towel, artificial leather, fishing net, setline.Brought inconvenience but its antistatic behaviour, water and oil repellant are relatively poor for using.
Antistatic and refuse water, refusing two kinds of opposite performances of oil, can to have simultaneously and have washing resistance be very difficult, and two kinds of performances all remain in good performance range extremely difficult especially.Nylon shioze fabric in the market only has antistatic or refuses a kind of in oil, water repellency.The antistatic processing of nylon fiber both at home and abroad mostly adopts physics, mechanical means to add surfactant or thereby conducting filler improves anlistatig performance.Specifically there is (1) to carry out hydrophilicity-imparting treatment with surfactant, improves the hygroscopicity of material, thereby reduce its resistivity, accelerate the loss of electric charge.But these class methods its antistatic effect simple to operation is not lasting, and especially effect is poorer in low wet environment; (2) utilize blended union to sneak into conductive fiber in the nylon shioze fabric, the stable and climate condition restriction not of this kind method electric conductivity, but it relates to physics, mechanical processing process, and complex process, and the manufactured goods feel is bad.And generally show as hydrophobicity through fiber after refusing oil, refusing water treatment, just do not have anlistatig performance.
A kind of textiles that contains the polyamide composition of antistatic epithelium shape resin parcel fiber is disclosed in Chinese patent CN101492885, this textiles filamentary is coated with antistatic epithelium shape resin bed, be pressed in below 3000V through the frictional electrification according to JIS L 1094 these textiless of standard test after JIS L 0217 No. 103 standard wash 20 times, this patent is by adding the antistatic and endurance issues that conducting particles has solved the nylon shioze fabric in the film forming agents such as EU, not improving its water and oil repellant and durability thereof.
Summary of the invention
The object of the invention is to provide a kind of and has simultaneously the water of refusing, oil repellent energy, and durability is splendid, feel antistatic nylon textiles preferably.
Technical solution of the present invention:
The filament surface coverage of this textiles has the epithelium resin bed, and above-mentioned epithelium resin bed is formed by EU resin and the fluorine resin with the end group generation cross-linking reaction of nylon fiber.The EU here is hydrophilic polyurethane, oh group generation condensation reaction as carboxyl and the above-mentioned Hydrophilicrto polyether type polyurethane of nylon tip group, need not to adopt conducting particles can improve the antistatic property of fabric, improve washing resistance simultaneously, and the EU resin there is certain elasticity to be particularly suitable for the nylon fiber of certain swellability.If adopt as antistatic additive commonly used and fluorine resin and use, can not produce simultaneously effect antistatic, that refuse water, refuse oil on nylon fiber.
The thickness of epithelium resin bed is 10～1000nm, and nano level epithelium is coated on filament and can exert an influence to fabric feeling.Fabric feeling after processing is more soft, and the combination between nano level epithelium and fiber is more firm, can improve the washing resistance of fabric.
The fluorine content of this textiles is 2000～4000ppm.If fluorine content is lower than 2000ppm, the water and oil repellant degree of textiles can not be guaranteed, and fluorine content is too high, can increase cost, but also can reduce washing resistance.
This textiles initial stage frictional electrification is pressed in below 2500V, refuses the water degree more than 4 grades, refuses oil content more than 4 grades.
After 0217 No. 103 standard-family's washing of JIS L 20 times, the antistatic property of this textiles is refused the water degree more than 3 grades below 2500V, refuse oil content more than 3 grades.
This processing technology is not particularly limited the form of formation fiber construct, can be long fiber, can be also staple fibre.The cross section shape of the monofilament of this fiber can be the profiled-cross-sections such as circle, triangle, flat, hollow.Also there is no particular limitation to filamentary thickness in addition.
The manufacturing process of product of the present invention comprises the following steps: successively
A. the preparation of machining textile;
B. working solution modulation (1L):
Hydrophilic film agent 5～100g
Water and oil repellant film forming agent 5～100g
Catalyst 0.1～10g
All the other are all soft water;
Wherein the hydrophilic film agent is the polyether-type hydrophilic polyurethane resin, and refusing the MJPZ agent is fluoroplast, and catalyst is organo-metallic compound etc.; Preferred 10～the 60g of use amount according to processing fabric and the agent of performance requirement hydrophilic film;
C. heat treatment: heat treatment is 5～20 minutes under the saturated steam conditions of 80～120 ℃ of temperature,
Make antistatic working solution evenly continuously bag invest the filament surface, do not produce between fiber and fiber
The state of green resin adhesion;
D. washing (accepting or rejecting depending on the processing situation): after heat treatment, be 50～80 ℃ of water in temperature
Washed in bath 0～20 minute, and removed the residual medicament that is adsorbed on fiber surface;
E. dry, finalize the design: fully dry after washing, bake out temperature is 80～150 ℃; After oven dry, setting temperature is 130～190 ℃, 0～120 second time.
In the scope of harmless purpose of the present invention, can also according to the colouring needs, contain ACID DYES, DISPERSE DYES and various dyeing used additives in fiber.
Processing method of the present invention is simple, solved the problem of the water and oil repellant of antistatic nylon textiles, and washing resistance is superior, and is soft.
