Background technology
The raising of Along with people's quality of life; The development of functional fibre and textiles receives people's attention gradually and likes; Functional fibre is meant also have the tencel of certain specific function the physical and mechanical properties that has except that general fiber, as has " three is anti-" fiber of waterproof, grease proofing, anti-pollution function; Its fabric will have certain waterproof, antifouling or refuse the wet goods function, can reduce the washing times of clothes, can reduce laundry labour intensity again.
Functional finishing agent is as the main auxiliary agent of producing functional fibre, and its application is also more and more wider.Discover; The fluoropolymer finishing agent not only has outside waterproof, the characteristic such as grease proofing, antifouling; Also have good chemical stability and heat endurance, be usually used in the finishing process of fabric, comfortable and easy to wear through the fabric of its arrangement; And show the grease proofing and antifouling property that does not possess with generally hydro carbons or waterproofing agent of organosilicon, become the focus of the research of current waterproofing agent.
Summary of the invention
The processing technology that the purpose of this invention is to provide a kind of PET functional fiber adds functional powders in the PET spinning melt, spins out the PET functional fiber.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of processing technology of PET functional fiber, with function powder and PET section co-blended spinning, process the PET functional fiber through the melt spinning of routine, and it is characterized in that:
Described function powder prepares process:
1) preparation of raw material: crosslinking agent 5-10wt%, fluoropolymer finishing agent 20-30wt%, resin finishing agent: 5-10wt%, nano titanium oxide 50-70wt%;
2) preparation of function powder: above-mentioned raw materials is evenly mixed, and under 100-130 ℃ of temperature dry 20min, dry back grind into powder, subsequent use;
The mass percent of said function powder and PET section is: the PET section: 90-95%, function powder is: 5-10%.
Described crosslinking agent is N, N '-methylene-bisacrylamide.
Described resin finishing agent dihydroxymethyl ethylene urea.
Described fluoropolymer finishing agent is the perfluorinated acrylate finishing agent.
The invention has the advantages that: crosslinking agent, fluoropolymer finishing agent, resin finishing agent and nano titanium oxide are processed functional powders; With PET section co-blended spinning; Process the PET functional fiber through the melt spinning of routine; The fabric that this functional fiber is made into not only keeps original intensity and toughness, and has waterproof, grease proofing and antifouling characteristic.
The specific embodiment
In order to make the public can fully understand technical spirit of the present invention and beneficial effect; The applicant will combine accompanying drawing that the specific embodiment of invention is described in detail below; But the applicant is not the restriction to technical scheme to the description of embodiment, anyly makes form but not the variation of essence all should be regarded as protection scope of the present invention according to the present invention design.
Embodiment 1
The processing technology of PET functional fiber comprises following two parts:
Functional agglomerate prepares process:
1) preparation of raw material: N, N '-methylene-bisacrylamide crosslinking agent 5wt%, perfluorinated acrylate finishing agent 25wt%, dimethylol ethylene urea resin finishing agent: 5wt%, nano titanium oxide 65wt%;
2) preparation of function powder: above-mentioned raw materials is evenly mixed, and under 120 ℃ of temperature dry 20min, dry back grind into powder, subsequent use;
Conventional melt spinning process:
With 95wt% function powder and 5wt%PET section co-blended spinning; Function powder and PET are processed melt; Melt comes out and is sent to spinneret assembly through measuring pump from screw extruder; Blowing cooling, melt thread cooling curing form as-spun fibre, oil at boundling on the as-spun fibre, winding shaping, spinning and through after be processed into the PET functional fiber.
Embodiment 2
The processing technology of PET functional fiber comprises following two parts:
Functional agglomerate prepares process:
1) preparation of raw material: N, N '-methylene-bisacrylamide crosslinking agent 8wt%, perfluorinated acrylate finishing agent 25wt%, dimethylol ethylene urea resin finishing agent: 7wt%, nano titanium oxide 60wt%;
2) preparation of function powder: above-mentioned raw materials is evenly mixed, and under 120 ℃ of temperature dry 20min, dry back grind into powder, subsequent use;
Conventional melt spinning process:
With 90wt% function powder and 10wt%PET section co-blended spinning, all the other processes are led to embodiment 1.
Embodiment 3 performance tests
According to GB/T14337-1993, test PET functional fiber and do not contain the PET fiber of functional powders, the long 10mm of sample, rate of extension is 15mm/min, the fracture strength of PET functional fibre is 3.42cNdtex
-1, the fracture strength of former PET fiber is 3.46cNdtex
-1, its intensity results is similar.
Above-mentioned PET functional fiber is made into lining, its performance test:
Note:
AATCC 22-1977 is divided into 5 grades, and grade is low more, and WATER REPELLENCY is good more, refuses 3 grades of water ranks, shows that being drenched the surface only has discontinuous small size wetting;
AATCC 118-1992 standard is divided into 8 grades of scorings, and the high more oil repellent that shows of grade can be good more;
AATCC 130-2000 standard is divided into the 1-5 level, and the high more effect of rank is good more.
