Recent Advances of Sustainable Textile Fabric Coatings for UV Protection Properties

Round 1

Reviewer 1 Report

In this work, the authors reviewed sustainable coatings for textile fabrics, the synthesis routes, and the merits concerning ultraviolet ray protection. Overall, the manuscript is informative and thus deserves publication in Coatings. However, the quality of the presentation and the English language must be improved before its publication. Below are some comments for the authors’ consideration. 

 

Major comments 

 

1. Section 1 lacks an introduction to sustainable textile fabric coatings. Please considering add a paragraph for this. 

 

2. The first paragraph of Section 2 should mention all coatings to be reviewed in this section. 

 

3. The paragraph spanning lines 106--218 is hard to digest due to a lack of organization. Is it feasible to tabulate the information therein? It is also helpful to have more comparisons between different studies in the text. 

 

4. Section 3 is not informative enough. Can you elaborate more on this section? 

 

5. In lines 45 and 46, do you mean oxygen and ozone molecules by “oxygen atoms”? 

 

Minor comments

 

6. A verb is missing in the sentence “Among these functions …” in lines 19 and 20. 

 

7. The sentence “There are various textile …” in lines 71—73 is hard to follow. Please rewrite it to be concise. 

 

8. In line 74, the word “Thus” is misused. There is no clear causal relationship between the sentences before and after it. 

 

9. In lines 80—81, the phrase “it is demand” is problematic. 

 

10. In lines 89—90, the sentence “Thus, displaying …” is very confusing. 

 

11. In line 102, a right parenthesis symbol “)” is missing for “(a”. 

 

12. In the caption of Figure 5, it is better to move the figure labels “(a)”, “(b)”, and “(c)” to the beginning of the corresponding explanatory sentences. 

 

13. In Section 2.2, a space needs to be added between “TiO2” and “NPs” in “TiO2NPs”. Similarly for “ZnONPs” and “SiO2NPs”. 

 

14. In line 223, the meaning of the word “This” is ambiguous. 

 

15. The newline character at the end of line 224 needs to be removed. 

 

16. In line 233, “SiO” should be “SiO2”.

(Page 12) Therefore, to achieve good UV blocking performance for the first class of UV protective agents, the band gap of semiconducting materials has to be tune via engineering of band gap. This is usually carried out by decorating and doping such kind of materials with peculiar metal nanoparticles bridging the gap and in turn narrow down the band gap to be suitable for absorption of UV rays [46-49,63-65]. On the other hand, for UV reflection action materials, the fabrication of nanocomposites-based coating layer ra-ther than only one component providing new synergistic feature for reflection of harmful UV rays [27,33-36]. In conclusion the UV blocking actions by various sustain-able textile fabric coatings is summarized in Fig.9.

(Page 2) Interestingly, UPF value can be straightforwardly evaluated in the range of 280 nm up to 400 nm based on Australian/ New Zealand Standard (AS/ NZS 4399:1996) according to the following equation:

UPF =  

Where E_λ refers to the relative erythemal spectral effectiveness (the action spec-trum), S_λ is the solar UV spectral irradiance for a typical summer period during midday in a clear sky condition, dλ indicates the increment in the wavelength, λ represents the wavelength (nm), and T_λ is the spectral transmittance of the specimen determined by the UV/ Vis spectrophotometer equipment [16-17]. The uncertainty of measurement is mainly depending on the accuracy and pression of spectrophotometer used, therefore vary from one to another.

2) Topic related comments:

Please check the following questions and

- Does inclusion of carbon nanofibers into yarns have any protection effect (possibly in other spectral ranges?)

(Authors’ Response) Thank you for reviewer comment and bring our attention to this point. Actually, there is no report so far studied the inclusion of carbon nanofibers in textile fabric coating for UV blocking. However, this is could be interesting point to study and carbon nanofibers could have sp3/sp2 hybridization and could influence and UV protection and achieve positive results. Also, precursors of carbon nanofibers will play a role. Therefore, our future study will be dedicated for this point.

- Does inclusion of (antimicrobial) silver into yarns have any protection effect?

(Authors’ Response) Thank you for reviewer comment and bring our attention to this point. Yes, the inclusion of AgNPs into yarns displayed good UV protection and antibacterial properties as well. Hence, new section and references are inserted in revised version enriched this point. Therefore, the following parts were added.

 

Inserted Section.

(Page 10) On the other hand, it is found that the inclusion of the antimicrobial silver nanoparticles (AgNPs) has UV protection capability against UV rays [57]. Therefore, the coating of PET with nanocomposite based on rGO-AgNPs enhanced the UV protection ability of that textile fabric [57]. Hence, the UPF value for the developed coated fabrics record 6145 compared to 34 for pristine cotton [57]. Eventually, the final product demonstrates not only a UV filtering capability, but antibacterial properties as well [57]. Over and above, AgNPs-ZnO composite cotton fabric coating was developed using fruit extract achieving good UV protection and antibacterial properties [58]. Hence, the UPF for coated cotton was found to be 70 compare to 7 for blank cotton sample [58].

- Which approaches of functional printing (e.g. inkjet printing for patterned UV coating) are applied in the field?

 

(Authors’ Response) Thank you for reviewer comment. Actually, the conventional heating or microwave irradiation can be utilized for that purpose. Recently, wool grease was extracted from coarse wool fleece using conventional heating or microwave irradiation. Afterward, has utilized at different concentrations of lanoline as a binder for pigment printing of wool, polyester fabric, polyester/ wool (65/ 35), and polyester/ cotton (65/ 35) using flat screen technique. Interestingly, these printed fabrics record a significant enhancement in UPF values compared to their original fabrics [66]. Hence, the following section with references were inserted in revised version and highlighted.

- Which links does the topic have to the field of "woven electronics" (UV protection and elementary functionalities at the same time)?

(Authors’ Response) Thank you for reviewer comment and bring our attention to this point. The link between those functionalized textiles and electronics can be found through the utilization of those coated fabrics with UV protective layers in different organic electronic devices like organic solar cells (OSCs). Such textiles can be utilized as both substrates and encapsulants to protect those solar cells used for outdoor applications. Therefore, an optimized fabrication approach was used to entirely spray coating technique to fabricate OSCs with a power conversion efficiency of 0.4%. Initially,  interface layer is deposited on the woven textile to form a smooth supporting layer for the subsequent spray-coated functional layers. Then, an encapsulant has been deposited on the top of the fabricated OSCs which enhances the durability and life time of the as-fabricated OSCs [67]. Hence, the following section with references were inserted in revised version and highlighted.

line 72: the term "harmful" should be explained (to whom? in what respect?)

(Authors’ Response) Thank you for reviewer comment. Actually, the UV rays are harmful to human and other living things and this clearly explained in introduction section as highlighted below.

(Page 2) The UV radiation affects humans and other living things negatively by inducing different physiological impacts with a plethora of acute and slow-rated consequences depending on the wavelength and energy [7]. UV-A is less energetic than UV-B; however, it can penetrate deeper through the second layer of the skin and the dermis, due to its longer wavelength [4-5] and hence causes the generation of reactive oxygen species (ROS) [7] and reactive nitrogen species (RNS) which in turn alter the lipids, proteins, and DNA of the cells [5-6]. These oxidative damages attributed by those highly reactive molecules and may result in wrinkle formation and cause aging of the skin, and may cause the development of skin cancer as a result of immunosuppression against infections [7] especially in the range from 360 nm to 380 nm [4]. On the other hand, UV-A exhibits lesser mutation effects than UV-B [5]

Reviewer 2 Report

The paper has considerably improved, but a few issues are missing.

- in the section on spherical nanoparticles inks, I expect a few lines on the alternative of metal-organic decomposition techniques e.g. on silver and their usage for textile coating

- text contains typos, e.g line 67 "rage"

- table on UPF is wonderful, but I expect error or uncertainty bars or at least hints in the headline about the order of magnitude

- some of the figures appear in inappropriate aspect ratio, please check.

(Authors’ Response) Thank you for reviewer comment. This has been considered in the revised version and highlighted. Therefore, new section displaying this method and its application was inserted in revised version and highlighted. Hence, the following section and references were inserted as follows.

Inserted Section

(Page 14) On the other hand, metal–organic decomposition (MOD) ink is another promising and alternative technique for utilization in coating of textile with metal for electronic ap-plications [68]. This process implies dissolving of metal source (eg. silver) in conven-ient solvent and then evaporation of solvent [69-70]. The choice of solvent is very crit-ical, after evaporation of solvent and decomposition of organic complexes volume of MOD inks is significantly diminished [71]. This approach is highly recommended for flexible printed electronics applications [72]. Inserted References

- text contains typos, e.g line 67 "rage"

(Authors’ Response) Thank you for reviewer comment. This has been considered in the revised version and highlighted. And rage was corrected to be range.

- table on UPF is wonderful, but I expect error or uncertainty bars or at least hints in the headline about the order of magnitude

(Authors’ Response) Thank you for reviewer comment. This has been considered in the revised version and highlighted. Hence, the general uncertainty percentage for UPF value was inserted in Table 1 headline and highlighted.

 

- some of the figures appear in inappropriate aspect ratio, please check.

(Authors’ Response) Thank you for reviewer comment. This has been considered in the revised version and highlighted. Hence, Figures 4 and 6 were replaced with suitable aspect ratio.

Reviewer 3 Report

Dear Authors,

I have reviewed the modified manuscript. Although I noticed moderate changes in the manuscript in terms of the language, I still do not believe the manuscript is ready for publication at this stage.

This paper would benefit from more thorough proofreading. It frequently makes it difficult to follow because it has numerous grammatical mistakes, such as verb agreement. After reorganizing the material, hiring a competent English language editor can be beneficial.
