Performance test
Hydroscopicity is tested:
The cloth specimen (10 ㎝ × 10 ㎝) of the suitable size of clip, is placed on 20 ± 1 DEG C by sample, balance 24 hours, and sample is laid on specimen holder under this condition in the temperature and humidity regulator of relative humidity 65 ± 2%, and make sample keep open and flat, test position is unsettled.Above sample, the distilled water of 0.05ml is dripped at 10 ㎝ places, measures liquid and drip the maximum diffusion length a of face transverse direction and longitudinal maximum diffusion length b at fabric after one minute.Every part of cloth specimen revision test 4 times, averages.
According to a, b of test gained, reference area S.Because the wetting shape of fabric is ellipse or circle, therefore press ellipse area formulae discovery
S=π*a*b (1-1)
Quick-drying is tested:
The cloth specimen of cutting 6 ㎝ × 6 ㎝, is placed in beaker oral area, and circle is tight, and specimen surface must be smooth and can not have distortion through weft yarn.Sample is placed on 20 ± 1 DEG C, relative humidity 65 ± 2% damping, balances 24 hours.Sample being connected beaker, to be placed on precision be on the electronic balance of 0.001, with the microscale sampler of 50 μ l from the eminence apart from specimen surface 1 ㎝, drips 0.05ml water in the non-coat side of sample.After 12 minutes, test sample connects the weight of beaker, every part of sample repeated test 4 times, averages, calculates its water evaporates rate E:
The weight (1-2) of E (%)=sample weight change/0.05ml water
Ultraviolet protection performance test:
Test textile ultraviolet protection index UPF (Ultraviolet Protection Factor) is adopted to evaluate textile ultraviolet radiation protective effect in this experiment [6-7].UPF is calculated as follows:
UPF = Σ λ = 290 400 E λ × S λ × Δλ Σ λ = 290 400 E λ × S λ × T λ × Δλ - - - ( 1 - 3 )
In formula:
λ---wavelength, nm; E λ---erythema spectral effects relatively;
S λ---solar radiation, W/ (m 2nm); T λ---the transmissivity (%) of sample during a certain wavelength;
Δ λ---wavelength interval, nm.
Washing methods:
Configuration 2g/L neutral wash solution, bath raio is 1:50, and on automatic reverse type washing machine, 40 DEG C of washing 10min, discharge washing lotion, and with 40 DEG C of clear water washing 5min, dehydration, repeatedly washs, repeat above-mentioned experiment, last low temperature drying.
Colorimetry:
Adopt CIE1976L*a*b* Colorimetry formula.
Result and discussion:
Select polyester textile first to carry out hydroscopic fast-drying arrangement, then carry out UV resistance top finish, respectively the preventing ultraviolet effect after the fabric washing 0 time, 5 times, 10 times, 15 times, 20 times after arranging and absorbing fast-drying effect are tested.Meanwhile, for analyzing the impact on mutual performance in differential combination arrangement, made single ultraviolet-proof in experiment respectively and arranged and the arrangement of single hydroscopic fast-drying, test result is in table 1,2.
Ultraviolet resistance
The ultraviolet resistance of fabric after the differential arrangement of table 1
Note: be 2.0 without differential finish fabric UPF value.
As shown in Table 1, after adopting UV resistance top finish, the ability and ultraviolet resistance of fabric is greatly improved, and after single UV resistance arranges (1 ~ No. 5 sample) and differential arrangement (6 ~ No. 10 samples), the UV resistance effect of fabric closely, illustrate that the effect that in differential arrangement, hydroscopic fast-drying arranges UV coating arranges does not affect substantially, through washing repeatedly, the UPF grade of fabric is still more than 30, fabric still has extraordinary ultraviolet protection grade, shows that differential finish fabric has good wash durability.
Moisture absorbing & quick drying property
The absorbing fast-drying performance of fabric after the differential arrangement of table 2
Note: be 2.1431cm without differential finish fabric average diffusion area 2, average moisture rate of evaporation is 35.5%.
As shown in Table 2, after differential arrangement, moisture pick-up properties and the quick-drying of polyester textile are all significantly improved, and after 5 washings, the moisture pick-up properties of polyester textile is compared with untrimmed sample and improve 5 times, and quick-drying performance improves nearly 2 times.Along with the increase of washing times, the hydroscopicity and the quick-drying performance that arrange rear fabric all slightly reduce, contrast with former state, even if through 20 washings, the moisture pick-up properties of differential arrangement polyester textile still retains the amplification more than 4 times, water evaporation rate keeps the raising of nearly 1.5 times, illustrates that the Moisture absorbing & quick drying property of this kind of differential arrangement to polyester textile increases significantly, and has higher wash durability after arranging.Arrange (1 ~ No. 5 sample) with single hydroscopic fast-drying to compare, the Moisture absorbing & quick drying property of differential finish fabric (6 ~ No. 10 samples) slightly decreases, its reason is that the UV resistance coating of fabric face the conduction of moisture and diffusion can produce certain impact, but from experimental result, this inhibition impact is little, and the fabric after differential arrangement still has very excellent moisture absorption and rapid-curing cutback performance.
The impact that differential arrangement becomes dyeing polyester fabric look
Become because the use of auxiliary agent can produce certain look to dyed fabric in finishing process, size is affected for what investigate that the differential arrangement that adopts in this experiment produces dyeing polyester, hot melt is adopted to dye to polyester textile, and then carry out differential arrangement, measure the aberration of fabric before and after arranging, dyeing and chromatism measurement result as follows.
Dyeing:
Padding liquor (5% Disperse Blue 2BLN, 5g/L migration inhibitor CJF-D604, pick-up 40%) → preliminary drying → dry → bake (210 DEG C, 1.5min) → reduction clearing (NaOH 2g/L, sodium hydrosulfite 1g/L, 1:25,15min, 90 DEG C) → washing → dry
The fabric chromatic aberration that the differential arrangement of table 3 causes
As shown in Table 3, the differential arrangement of UV resistance-hydroscopic fast-drying is little on the impact of dyeing polyester fabric aberration, and before and after arranging, aberration grade is all in 4-5 level, illustrates that this kind of differential Collator Mode also may be used for the Special Finishing of dyeing polyester fabric.
Conclusion:
By carrying out differential finishing functions to polyester textile pros and cons, give polyester textile UV resistance and the different performance of hydroscopic fast-drying two kinds.First carry out hydroscopic fast-drying arrangement, carry out the UV resistance top finish in front again, after arranging, the ultraviolet protection performance of fabric and hydroscopic fast-drying all have and significantly improve, and influencing each other between pros and cons two kinds arrangement is very little, by to the chromatism measurement arranging front and back dyed fabric, prove that this differential arrangement is also very little on the impact of aberration.Give fabric pros and cons two kinds different performances by differential arrangement, method is simple, and goes for the textile finishing of other type.
