Performance test

Hygroscopicity is tested:

The cloth specimen (10 × 10) that clip is appropriately sized, is placed on 20 ± 1 DEG C, the tune of relative humidity 65 ± 2% by sample Balancing 24 hours in temperature damping case, and sample is laid on specimen holder under this condition, make sample keep open and flat, test position hangs Empty.Above sample, drip the distilled water of 0.05ml at 10, measure liquid after one minute and drip the horizontal maximum expansion in face at fabric Dissipate length a and maximally diffuse length b with longitudinal.Every part of cloth specimen repeats to 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 ellipsoid Long-pending formula calculates

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 palpus is smooth and can not have torsion through weft yarn Bent.Sample is placed on 20 ± 1 DEG C, relative humidity 65 ± 2% damping, balance 24 hours.Sample is connected beaker it is placed on precision and be On the electronic balance of 0.001, with the microscale sampler of 50 μ l from the eminence away from specimen surface 1, drip 0.05ml water in sample not Coat side.After 12 minutes, test sample connects the weight of beaker, every part of sample retest 4 times, averages, calculates its moisture content and steam Rate E of sending out:

The weight (1-2) of E (%)=sample weight change/0.05ml water

Ultraviolet protection performance test:

This experiment uses test textile ultraviolet protection index UPF (Ultraviolet Protection Factor) textile ultraviolet radiation protective effect is evaluated^[6-7].UPF is calculated as follows:

$\mathrm{UPF}=\frac{\underset{\mathrm{\λ}=290}{\overset{400}{\mathrm{\Σ}}}{E}_{\mathrm{\λ}}\×S_{\mathrm{\λ}}\×\mathrm{\Δ\λ}}{\underset{\mathrm{\λ}=290}{\overset{400}{\mathrm{\Σ}}}{E}_{\mathrm{\λ}}\×S_{\mathrm{\λ}}\×T_{\mathrm{\λ}}\×\mathrm{\Δ\λ}}---(1-3)$

In formula:

λ wavelength, nm； E_λErythema spectral effects relatively；

S_λSolar radiation, W/ (m²·nm)； T_λThe 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 40 DEG C of washing 10min on automatic reverse type washing machine, discharge is washed Liquid, with 40 DEG C of clear water washing 5min, dehydration, repeatedly washs, repeats above-mentioned experiment, last low temperature drying.

Colorimetry:

Use 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 to arranging after Fabric washing 0 time, 5 times, 10 times, 15 times, preventing ultraviolet effect after 20 times and absorbing fast-drying effect are tested.Meanwhile, for Analyze the impact on mutual performance during differential combination arranges, experiment has been made single ultraviolet-proof respectively and has arranged and single Hydroscopic fast-drying arrange, test result is shown 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 using 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 is non- Very close to, illustrate that the effect that in differential arrangement, UV coating is arranged by hydroscopic fast-drying arrangement does not the most affect, through repeatedly Washing, the UPF grade of fabric is still above 30, and fabric still has extraordinary ultraviolet protection grade, shows differential arrangement 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 area², average moisture evaporation rate 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, After 5 times are washed, the moisture pick-up properties of polyester textile improves 5 times compared with untrimmed sample, and quick-drying performance improves Nearly 2 times.Along with the increase of washing times, after arrangement, hygroscopicity and the quick-drying performance of fabric the most slightly reduce, and contrast with former state, i.e. Making through 20 washings, the moisture pick-up properties of differential arrangement polyester textile still retains the amplification more than 4 times, and water evaporation rate keeps near The raising of 1.5 times, illustrates that the Moisture absorbing & quick drying property of polyester textile is increased significantly by this kind of differential arrangement, and arranges it After there is higher wash durability.Compared with single hydroscopic fast-drying arrangement (1～No. 5 sample), differential finish fabric The Moisture absorbing & quick drying property of (6～No. 10 samples) slightly decreases, and its reason is that the UV resistance coating of fabric face can moisture Conduction and diffusion produce certain impact, but from the point of view of experimental result, the impact of this inhibition is little, after differential arrangement Fabric still there is the most excellent moisture absorption and rapid-curing cutback performance.

The differential arrangement impact on dyeing polyester fabric discoloration

Finishing process can produce certain discoloration to dyed fabric, for investigating institute in this experiment due to using of auxiliary agent What dyeing polyester was produced by the differential arrangement used affects size, uses hot melt to dye polyester textile, carries out Differential arrangement, measures the aberration of fabric before and after arranging, and dyeing and chromatism measurement result are as follows.

Dyeing:

Padding liquor (5% Disperse Blue 2BLN, 5g/L migration inhibitor CJF-D604, pick-up 40%) → preliminary drying → drying → roasting Dry (210 DEG C, 1.5min) → reduction cleaning (NaOH 2g/L, sodium hydrosulfite 1g/L, 1:25,15min, 90 DEG C) → washing → drying

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, arranges Front and back aberration grade is all in 4-5 level, illustrates that this kind of differential Collator Mode can be used for the Special Finishing of dyeing polyester fabric.

Conclusion:

By polyester textile positive and negative being carried out differential finishing functions, give polyester textile UV resistance and hydroscopic fast-drying two Plant different performances.First carrying out hydroscopic fast-drying arrangement, then carry out the UV resistance top finish in front, after arrangement, the ultraviolet of fabric is prevented Protect performance and hydroscopic fast-drying be all greatly improved, and positive and negative two kinds arrange between influence each other the least, by arrangement The chromatism measurement of dyed fabric front and back, it was demonstrated that this differential arrangement is the least on the impact of aberration.Composed by differential arrangement Giving two kinds of different performances of fabric positive and negative, method is simple, it is possible to be applicable to other type of textile finishing.
