Description
Technical Field
The application relates to the field of special fabric finishing processes, in particular to a chiffon fabric finishing process.
Background
Chiffon is a yarn product (not a spinning product) in silk products, is named from the transliteration of Chiffon in English, means a light, thin and transparent fabric, and has the characteristics of light, thin, transparent, soft and elegant fabric. In recent years, due to the rapid development of chemical fiber technology, the original real silk is replaced by the chemical fiber. At present, the hand feeling and style of chemical fiber chiffon are very close to or similar to real silk, so the chiffon is often called as real silk chiffon or chemical fiber chiffon.
Although chiffon fabrics on the market have various colors, chiffon with light color or plain color is popular because of the elegant aesthetic feeling. Although the plain chiffon has a light and elegant appearance, the whole chiffon fabric has no change, is inevitably too monotonous and has weak visual impact force in order to keep the light appearance of the plain chiffon. The market needs a finishing process which has visual impact on the basis of keeping the plain appearance of the chiffon fabric.
Disclosure of Invention
In order to overcome the defects that the appearance of the conventional chiffon fabric is too monotonous and the visual impact force is weak in order to maintain the simple and elegant appearance, the application provides a chiffon fabric finishing process.
The application provides a chiffon fabric finishing process which adopts the following technical scheme:
a chiffon fabric finishing process comprises the following process steps:
s1, printing, namely printing the photocuring slurry on the grey cloth according to the designed pattern to obtain printed grey cloth;
s2, carrying out photocuring on the printed gray fabric obtained in the step S1 to obtain a cured gray fabric;
s3, pre-shrinking, namely pre-shrinking the solidified gray fabric obtained in the step S2 to obtain a chiffon fabric;
the light-cured slurry comprises the following raw materials in parts by mass:
100 parts of paste;
100 portions and 120 portions of light-cured resin;
6-10.5 parts of an auxiliary agent;
the auxiliary agent at least comprises a photoinitiator.
By adopting the technical scheme, the photocuring slurry is printed on the grey cloth and photocuring treatment is carried out, and the size of the cured photocuring resin is stable, so that even if pre-shrinking treatment is carried out subsequently, the shrinkage rate of the grey cloth printed with the photocuring slurry is small, and the fabric structure is still loose. While the part not printed with the photo-setting paste will undergo a significant dimensional change in the pre-shrinking step, and the fabric structure shrinks and becomes compact. Thus, the fabric of the loose structure part and the fabric of the tight structure part have strong visual difference due to different appearances, thereby having large visual impact.
Compared with the conventional 'plain' chiffon on the market at present, the chiffon fabric obtained by the finishing process in the application still can keep the overall simple and elegant appearance because the chiffon fabric is not printed and dyed; but the parts with different structural densities can generate larger visual impact force because of larger visual difference, so that the chiffon fabric becomes more flexible on the basis of keeping the elegant appearance.
Optionally, the light-cured resin comprises the following components in percentage by mass:
tetrahydrofurfuryl acrylate 10-12%;
88-90% of waterborne polyurethane acrylic resin.
By adopting the technical scheme, the tetrahydrofurfuryl acrylate has better dilution performance and better dilution capability and dispersibility compared with the traditional monomers such as DPGDA, TMPTA, TPGDA and the like. In addition, since the chiffon raw material is generally hydrophobic polyester fiber, and the light-cured resin needs to be an aqueous resin for environmental protection, the bonding force between the light-cured resin and the fiber is weak. The tetrahydrofurfuryl acrylate monomer has low viscosity, high curing speed and good wettability to a substrate, and can greatly improve the adhesive force of the light-cured resin to fibers. Meanwhile, the annular structure of the chiffon fabric can bring better toughness to the light-cured resin, so that the wearability of the chiffon fabric is improved.
Optionally, the auxiliary agent is a photoinitiator, an emulsifier and palmityl alcohol according to a mass ratio of (5-6): (4-5): (0.4-0.5).
By adopting the technical scheme, the emulsifier can improve the dispersion effect of each material in the system, and the palmitol can play a role in emulsification assistance.
Optionally, in the auxiliary agent, the mass ratio of the emulsifier to the palmitol is 10: 1.
by adopting the technical scheme, the inventor finds that when the mass ratio of the emulsifier to the palmityl alcohol is about 10: 1, the light-cured slurry can keep stable performance for a long time on the basis of light-shielding storage.
Optionally, the paste comprises the following raw materials in percentage by mass:
the additive at least comprises ammonium tartrate;
the thickening component is one or a mixture of chitosan, sodium alginate and carboxymethyl cellulose.
By adopting the technical scheme, the chitosan, the sodium alginate and the carboxymethyl cellulose are all natural polymer materials, are safe and nontoxic and have good affinity with human skin. In addition, chitosan also has a good antibacterial effect, and chiffon belongs to the fabric which looks cool and is stuffy when being worn, so that the chitosan added into the thickening component can not only play a good thickening effect, but also play a certain antibacterial role.
Optionally, the additive is ammonium tartrate and urotropine according to a mass ratio of (2-3): (3-5).
By adopting the technical scheme, the shrink-proof principle in the technical scheme is that a layer of light-cured resin is printed and photocured on the surface of the fiber which is easy to shrink, and because the shrinkage rate of the light-cured resin is small, in the pre-shrinking step, the light-cured resin can play a role in positioning the wrapped fiber, so that the shrinkage amount of the fiber is reduced.
The urotropine can be used as a shrink-proof agent of the fabric, so that the shrink-proof performance of the fabric can be improved by further adding the urotropine into the paste, and the dimensional stability of the fabric printed with the photocuring slurry is further improved.
Optionally, the thickening component is chitosan and carboxymethyl cellulose in a mass ratio of 2: (3-5).
By adopting the technical scheme, generally speaking, the conventional knowledge is that after a plurality of thickening components are mixed, the viscosity of the mixture may even be reduced, because the water holding capacity of different thickening components is different, the thickening component with strong water holding capacity can capture the water of the thickening component with weaker water holding capacity, so that the viscosity of the mixture is reduced, and then the antagonism of the thickening component is generated. In particular, carboxymethylcellulose is not resistant to dilution, and it is conventionally believed that compounding carboxymethylcellulose with other thickeners tends to produce an antagonistic effect, resulting in a decrease in viscosity.
The inventor surprisingly found that on the basis of the same addition amount of the thickening component, the combination of chitosan and carboxymethyl cellulose can obtain obviously better thickening effect compared with the single use of chitosan or single use of carboxymethyl cellulose. This is probably due to the complex synergistic thickening effect between the two thickening components, both of which are polysaccharide macromolecules.
Optionally, 10-15 parts of an antibacterial agent is further added into the photocuring slurry, and the antibacterial agent comprises the following raw materials in percentage by mass:
through adopting above-mentioned technical scheme, the chiffon yarn is comparatively loose because moisture absorption, perspire the performance all relatively poor, and the structure of chiffon surface fabric, and the wearer still can feel sultry, and because sweat is difficult for evaporating, the skin surface of wearer often breeds the bacterium easily. And the antibacterial agent is added into the photocuring slurry, so that copper ions with an antibacterial effect can be introduced, and the chiffon fabric has a certain antibacterial effect to improve the wearing comfort.
The didecyl dimethyl ammonium bromide is added into the antibacterial agent to serve as a dispersing agent, so that the dispersing uniformity of copper ions in a system can be improved, and the uniform antibacterial property of the finally obtained chiffon fabric is improved; didecyl dimethyl ammonium bromide itself also has some antimicrobial effect, and thus didecyl dimethyl ammonium bromide is able to provide a dispersing and antimicrobial effect.
Further, the inventor unexpectedly finds that whether urotropine is added into the paste or not has obvious influence on the antibacterial performance of the finally obtained chiffon fabric in a control experiment, which indicates that the urotropine in the paste and the antibacterial agent have synergistic antibacterial effect. Further, the inventors found that the antibacterial property of the system is reduced after the didecyl dimethyl ammonium bromide is replaced by the sodium dodecyl benzene sulfonate, and the antibacterial effect of the system is obviously superior to the intrinsic antibacterial effect of the didecyl dimethyl ammonium bromide, which indicates that the didecyl dimethyl ammonium bromide and the urotropine have a synergistic antibacterial effect.
Optionally, the step S2 includes the following steps:
s21, performing primary curing, namely performing photocuring on the printed gray fabric obtained in the step S1 for 8-10S, wherein the power of a photocuring lamp is 2kW, so as to obtain primary cured gray fabric;
s22, carrying out ultrasonic treatment, namely carrying out ultrasonic treatment on the primary cured gray fabric obtained in the step S21, wherein the ultrasonic power is 800 kW and 900kW, and the treatment time is 50-70S, so as to obtain ultrasonic gray fabric;
and S23, carrying out secondary curing, namely carrying out photocuring on the ultrasonic grey cloth in the step S22 for 6-7S, wherein the power of a photocuring lamp is 2kW, so as to obtain the cured grey cloth.
Through adopting above-mentioned technical scheme, photocuring thick liquids are after preliminary solidification, and the top layer has solidified basically, but inside not completely cured yet, for comparatively thick and sticky state, utilize the ultrasonic wave to handle this moment, can make thick and sticky photocuring thick liquids constantly permeate into the pit on fibre surface to improve the adhesion fastness of photocuring thick liquids and fibre. The subsequent secondary curing can completely cure the light-cured slurry and ensure high adhesion to the fiber.
In addition, the inventor unexpectedly finds that the antibacterial effect of the chiffon fabric subjected to ultrasonic treatment is improved to a certain extent, probably because ultrasonic waves can catalyze urotropine and copper ions to generate a complex with a good antibacterial effect, and the antibacterial effect of the complex is better than that of pure copper ions, so that the finally obtained chiffon fabric has a better antibacterial effect.
Optionally, in step S22, the ultrasonic power is 850kW, and the ultrasonic time is 60S.
By adopting the technical scheme, the inventor finds that the ultrasonic power and the ultrasonic time during ultrasonic treatment need to be strictly controlled, and once the ultrasonic time is too long or the ultrasonic power is too high, the adhesion between the photocuring slurry and the fibers is reduced. This is because, although the photo-setting paste has undergone primary setting, the surface-set photo-setting paste may crack once it is over-sonicated, and the over-sonication may also shake the photo-setting paste off the fibers.
In summary, the present application includes at least one of the following beneficial technical effects:
1. by printing the photo-curing slurry on the grey cloth and carrying out photo-curing treatment, the part printed with the photo-curing slurry is highly stable in size during subsequent pre-shrinking treatment, while the unprinted part shrinks in size during subsequent pre-shrinking treatment, and the chiffon fabric still can keep a simple and elegant look and feel due to the fact that the printing and dyeing are not carried out, but the part with a loose structure and the part with a tight structure can generate stronger visual difference due to different looks and feels;
2. by limiting the composition and the proportion of the photocuring slurry, the photocuring slurry with better stability can be obtained, and the adhesion fastness of the photocuring slurry and the chiffon fabric can be improved;
3. by further adding an antibacterial agent into the photocuring slurry, the chiffon fabric obtained through final finishing has a good antibacterial effect; in addition, the inventor unexpectedly found that didecyl dimethyl ammonium bromide in the antibacterial agent and urotropin in the auxiliary agent have a synergistic antibacterial effect;
4. by adding the ultrasonic treatment step in the photocuring process, the adhesion fastness of the photocuring slurry and the chiffon fabric can be improved, and the antibacterial performance of the chiffon fabric can be further improved.

Comparative example

Performance detection method and performance data
Anti-shrinkage performance of photo-curing slurry
In each example, the printed pattern printed in step S1 is formed by uniformly distributing 1cm by 1cm squares, and the distance between adjacent printed squares is 1cm, that is, 1cm by 1cm squares printed with the photo-setting paste are uniformly distributed on the printed gray fabric obtained in step S1.
And then taking the finally obtained chiffon fabric, randomly measuring the area X of 3 printing squares, and calculating the shrinkage rate, wherein the shrinkage rate calculation formula is as follows:
shrinkage was 100% (1-X).
The smaller the shrinkage rate, the better the shrinkage resistance of the photocurable paste.
Second, antibacterial property of chiffon fabric
The experimental bacteria are Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC6538), and the bacterial suspension is prepared according to the specification in the 2002 edition of 'Disinfection technical Specification'. The experimental procedure is that chiffon fabrics in each example and comparative example are taken, a piece of chiffon fabric printed with the photo-curing slurry with the size of 1cm x 1cm is cut (the comparative example 1 is a piece of chiffon fabric with the size of 1cm x 1cm is cut randomly), the chiffon fabric is placed into a sterile test tube, 10mL of bacterial suspension is added, and the mixture is subjected to heat preservation and oscillation in a constant-temperature water bath at the temperature of 20 ℃ for 10 min.
And then 0.5mL of the treated bacterial suspension is taken and diluted to 5mL by distilled water, 1mL of the diluted bacterial suspension is taken and inoculated into a sterile culture dish, an agar culture medium is added and mixed uniformly, the mixture is cultured for 72h in an incubator at 37 ℃, the number of plate bacterial colonies on the culture dish is observed, and the killing rate is calculated.
The higher the kill rate, the better the antibacterial effect.
Third, the anti-friction performance of chiffon fabric
The chiffon fabric in each of the examples and comparative examples was taken as a test sample, the size was 15cm by 15cm, the initial weight M0 of the test sample was measured, the test sample was wrapped and fixed on a test iron plate having a size of 10cm by 10cm, a base fabric (pure cotton yarn card twill fabric, 20 x 16 yarn count, and a gram weight of 240gsm) was wrapped and fixed on a test table, then a 1kg weight was placed on the test iron plate to closely attach the test sample to the base fabric, and then the test sample was moved back and forth 100 times at a single movement distance of 50cm by 2, and the final weight M1 of the test sample after completion of the test was measured. And (3) calculating the wear rate of the sample, wherein the wear rate calculation formula is as follows:
the wear rate was (M0-M1)/M0 at 100%.
The higher the wear rate, the poorer the friction resistance of the chiffon fabric, and the poorer the bonding fastness of the light-cured slurry and the chiffon fabric.
The test performance data are reported in the following table:
conclusion
As can be seen by comparing the data of comparative example 1 and example 1, the shrinkage of the chiffon fabric printed with the photo-setting paste part was only about 12% even though the chiffon fabric was pre-shrunk, and the shrinkage of the chiffon fabric not printed with the photo-setting paste part was measured by the inventors to reach 50-60%.
It can be seen from the data of comparative examples 4 and 6-8 that the shrinkage resistance and the abrasion resistance of the photo-cured slurry printed on the chiffon fabric can be obviously improved by further introducing the emulsifier and the co-emulsifier of the palmitol into the auxiliary agent.
It can be seen from the data of comparative examples 11-15 that the shrinkage resistance and abrasion resistance of the photo-setting paste printed on the chiffon fabric can be significantly improved by using chitosan and carboxymethyl cellulose as thickeners, compared to the addition of a single thickening component. Shows that the chitosan and the carboxymethyl cellulose have synergistic effect on the performance of the paste or the light-cured slurry.
It can be seen from the data of comparative examples 15-18 that the shrinkage resistance of the chiffon fabric can be significantly improved by further adding urotropine to the photo-curing slurry. This is probably due to the intrinsic shrink-proof effect of urotropine on chiffon fabrics.
It can be seen from the data of comparative examples 18-20 that although the anti-bacterial agent is further added into the photo-curing slurry to affect the anti-shrinkage performance and the anti-friction performance of the chiffon fabric in a small range, the anti-bacterial performance of the chiffon fabric is greatly improved, and a better anti-bacterial effect can be obtained.
It can be seen by comparing the data of examples 21, 23 that didecyl dimethyl ammonium bromide, also as a surfactant, has an antimicrobial effect significantly superior to that of sodium dodecylbenzenesulfonate. Further comparing the data of examples 21 and 24, it can be seen that urotropin not only has the effect of shrink proofing agent, but actually, urotropin also has a certain influence on the antibacterial performance of chiffon fabric.
By comparing the data of the examples 24-25, it can be seen that the antibacterial effect of the chiffon fabric is reduced by about 6% by replacing didecyl dimethyl ammonium bromide with sodium dodecyl benzene sulfonate on the basis of not adding urotropine; in combination with the data of examples 21 and 23, it can be seen that the antibacterial effect of the chiffon fabric is reduced by about 11% by replacing didecyl dimethyl ammonium bromide with sodium dodecyl benzene sulfonate on the basis of adding urotropine. Namely, on the basis of adding the urotropine, the influence of the didecyl dimethyl ammonium bromide on the antibacterial performance of the chiffon fabric is obviously improved, so that a synergistic antibacterial effect exists between the urotropine and the didecyl dimethyl ammonium bromide.
It can be seen from the data of comparative examples 21 and 26 that the specific two-step curing and ultrasonic treatment process not only can significantly improve the influence of the photo-curing slurry on the shrinkage resistance of the chiffon fabric, but also can further improve the adhesion fastness of the photo-curing slurry on the chiffon fabric. In addition, the antibacterial performance of the chiffon fabric is also obviously improved, which is unexpected by the inventor.
Comparing the data of examples 26 and 29-30, it can be seen that the antibacterial performance of the chiffon fabric is not greatly affected by the presence or absence of didecyl dimethyl ammonium bromide in the photo-curing slurry, while the antibacterial performance of the chiffon fabric is greatly affected by the sufficient addition of urotropine in the photo-curing slurry. This shows that under the action of ultrasonic wave, some components of urotropine and antibacterial agent form obvious synergistic antibacterial action. Probably, under the catalysis of ultrasonic wave, urotropine reacts with copper ions in the antibacterial agent to generate a copper ion complex, and the copper ion complex has better antibacterial effect than the copper ions alone.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
