Abstract
The invention discloses a processing technique of PET functional fibers. The processing technique has the following steps: preparing a crosslinking agent, a fluorine-containing polymer finishing agent, a resin finishing agent and nanometer titania into functional powder; carrying out blended spinning on the functional powder and PET chips; and preparing the PET functional fibers through conventional melt spinning. The fabric woven with the functional fibers not only maintains the original strength and toughness but also has the characteristics of water proofing, oil proofing and dirt proofing.
Description
Technical field
The present invention relates to a kind of processing technology of PET functional fiber.
Background technology
Raising along with people's quality of life, the development of functional fibre and textiles is subjected to people's attention gradually and likes, the physical and mechanical properties that functional fibre refers to have except general fiber, the tencel that also has certain specific function, 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, the finishing process that is usually used in fabric, fabric through its arrangement is comfortable and easy to wear, 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 solution used in the present invention is: a kind of processing technology of PET functional fiber, with function powder and PET section co-blended spinning, make the PET functional fiber by the melt spinning of routine, and it is characterized in that:
Described function powder preparation process is:
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, standby;
The mass percent of described 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 made functional powders, with PET section co-blended spinning, make the PET functional fiber by 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 describe in detail the specific embodiment of invention below by reference to the accompanying drawings; but the applicant is not restriction to technical scheme to the description of embodiment, anyly makes form but not the variation of essence all should be considered as protection scope of the present invention according to the present invention's design.

2) preparation of function powder: above-mentioned raw materials is evenly mixed, and under 120 ℃ of temperature dry 20min, dry back grind into powder, standby;
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 fabric, its performance test:
Note:
AATCC 22-1977 is divided into 5 grades, and grade is more low, and WATER REPELLENCY is more good, 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 more high oil repellent that shows of grade can be more good;
AATCC 130-2000 standard is divided into the 1-5 level, and the more high effect of rank is more good.
