Further, in the step 3 of the preparation of described polyester staple fiber, oil bath drawing-off groove temperature is 60-75 DEG C, and oven temperature is 110-120 DEG C, heat setting temperature 125-150 DEG C, and heat-setting time is 15-30min.
Further, the mass ratio of described polyester staple fiber to coated environmental protection essence capsule complete in the step 1 of the absorption of aromatic and ethanolic solution is (0.1-0.25): 1.
Further, described polyester staple fiber is 1:10 to polyester staple fiber described in the step 2 of the absorption of aromatic and aromatic mass ratio.
The invention has the beneficial effects as follows:
1, the fragrant fiber that dipping blending method and spray process are made belongs to physical modification, not only do not change the macromolecular chain structure of high polymer, remain the intrinsic advantage of original fiber, with the addition of again new material simultaneously, give fiber some new performance by changing aggregated structure, wearability is also had greatly improved;
2, flood method that is blended and spray process simple, the fibrous material that combination property is good can be obtained, there is larger theory and practical value.Adopt this suction to compose fragrant method, fragrant fiber without any restriction, easily forms specific fragrance effect to the boiling point of aromatic substance;
3, after aromatic odor disperses, the aromatic odor also can liked according to oneself re-starts perfuming process, and the aromatic odor of fragrant fiber can be reselected.
The fragrant fiber that the present invention produces has multiple odor type, can bring health environmental protection, the anxiety that contributes to releiving, alleviates anxiety, relieving mental strain and helping sleep, and to human temperature and non-stimulated, most people are ready to accept.
Accompanying drawing explanation
Fig. 1 is fabrication processing of the present invention.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Embodiment
With reference to shown in Fig. 1, a kind of preparation method of aromatic polyester fiber, comprises the preparation of polyester staple fiber and polyester staple fiber to the absorption of aromatic;
The preparation of described polyester staple fiber comprises:
Step 1) drying of cutting into slices, adopt vacuum drum drying box to carry out drying to section, vacuum 0.8Mpa, drying time is 20-22 hour, and baking temperature is 60-90 DEG C.Baking temperature is higher, and better, but the viscosity that too high baking temperature can make PET cut into slices reduces degree increase to dry effect, even makes section its colour changed into yellow, affects spinning quality.Along with the continuity of drying time, moisture is constantly vaporized, the Mass lost of wet stock, and the free water content of material levels off to zero;
Step 2) dried PET section carries out melt spinning on LHFJ03 spinning machine, melt arrives Xu Leng heat preservation zone after spinnerets ejection, forms melt stream, by cooling quench curing molding, then feeding means is arrived, make as-spun fibre boundling, last winding shaping by oil supply feedwater, spinning temperature is 250-290 DEG C, Xu Leng temperature is 150-180 DEG C, lateral blowing wind speed is 0.35m/s, and wind-warm syndrome is 19-20 DEG C, and winding speed is 1300m/min;
Step 3) silk of winding is carried out boundling process, through oil bath drawing-off, add polyester staple fiber finish, its weight is the 2%-3% of raw material gross weight simultaneously, after oil bath, carry out stretch processing, send into again after stretching crimping machine curling, then carry out drying and shaping to baking oven, deliver to cutting machine again from dryer silk out to cut off, oil bath drawing-off groove temperature is 60-75 DEG C, and oven temperature is 110-120 DEG C, heat setting temperature 125-150 DEG C, the time is 15-30min;
The absorption of described polyester staple fiber to aromatic comprises:
Step 1) by complete coated environmental protection essence capsule with mass ratio (0.1-0.25): 1 is dissolved in ethanolic solution and is diluted to aromatic;
Step 2) polyester staple fiber is immersed in aromatic, keep a period of time at ambient pressure, take out oven dry after fully sucking and obtain fragrant fiber, described polyester staple fiber and aromatic mass ratio are 1:10; Or after adopting spray process to process polyester fiber, cure obtained.
Polyester staple fiber to the absorption principle of spices is: the process of polyester fiber absorption perfume molecules is by spices affinity in fiber, i.e. the difference in chemical potential of spices in solution and fiber, to be adsorbed spices by fiber micropore and spread.
Further, the spices selected by the present invention has following requirement: as far as possible from the extract of plant, requires, except the sense of smell with pleasant aroma, also will have certain physical therapy function simultaneously.Such as wormwood fragrance can have certain syngignoscism and natural anthelminthic effect.Therefore the aromatic that the present invention adopts roughly has following features: the plant perfume adopted, has pleasing scent, health environment-friendly, the anxiety that contributes to releiving, alleviates anxiety, relieving mental strain and helping sleep, and to human temperature and non-stimulated, most people are ready to accept.Such as Jasmine, rose, lavender, cloves, violet, wormwood, gardenia, apple, lemon, pineapple, orange etc.
Table 1 is for carrying out performance test table after fiber test manufacture
As shown in Table 1, carry out performance test after fiber test manufacture, aromatic remains (28 days): 93%, implements long lasting quality test grading: 4 grades (the highest 5 grades) according to Nippon Standard JISL0217.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
