I have coated emulsion through layer bi layer coating technique. after FTIR analysis there is no shift of peak occur in coated and un-coated textile. I want its description or reason behind, there might be no chemical interaction between emulsion and textile , only physical attraction that causes no shift of peak, or what else?
Relevant answer
Answer
You used a cotton fabric and coated the surface of the fiber with your L-b-L material and tried to see the interaction via FTIR analysis. However, the diameter of cotton fiber is usually 11-22 micrometers and its surface area is on the order of a fraction of M2/g. With such a low surface area, the information from the interfacial interaction between the fiber and the first monomolecular layer equivalent of the L-b-L material is nearly impossible to observe via FTIR analysis. You need the substrate with the surface area of minimum of several tens, if not hundreds of M2/g surface area to comfortably study the interfacial interaction. Thus, the information you are seeking is at least a few orders if not several orders of magnitude weaker than feasible sample. The majority of the information comes from the bulk cotton fabric and bulk L-b-L layers.

why sometimes natural bacterial consortia give a higher percentage of decolorization but have a lower COD removal rate
Relevant answer
Answer
Awais Iqbal Bacterial decolorization is mostly dissimilatory, for instance azo dyes; is through breaking of the Azo N=N bond making the dye colorless. To lower the COD values you need assimilatory decolorization/mineralization where the dye is used as a carbon or nitrogen or both sources for growth. See

Maybe remark of article alternative.
I wrote a few years ago article (in Slovak) trying to adapt the rebound effect (RE) analysed very often in the energy and material field on the marketing decision process.
I am recently working on a survey aiming to find if there could be a benefit for fast fashion (FF) producers to participate actively in second-hand markets, swap, upcycling, and other alternative fashion processes.
Looking at FF impact on the market seems to me as a very traditional RE. If the rebound principle is included in the textile and fashion purchase decision, "sustainability" education will fail their goals massively.
The question is how to prove the RE impact of FF offer? I can imagine using statistical data by traditional market (1970) and new market (2000) with change analysis in the different price range. As a citizen of the post-communist country, I have no relevant data about pre FF markets.
Are there other alternatives how to prove the rebound effect by customer decision about clothes and textile purchase?

What is the experimental method (standard) for measuring cleaning performance of the textiles?
Relevant answer
Answer
Cleaning performance of washing machines is assessed using IEC 60456 standard. The wash load consists of standardized cotton or polyester-cotton textilex. Stain strips with five different, standardized stains are used to rate the cleaning capailities of the washing machine / program. The color of the unwashed stain is compared to the color of the stain after washing to assess the cleaning capability.
The method could be easily adapted with other textiles or other (use-case specific) stains.

Dear Researchers,
In Textile Reinforced Concrete is a novel construction material consisting of a cementitious binder and a textile reinforcement. Without using a course aggregate why the topic is named as Textile Reinforced Concrete? and why the topic is not named as  Textile Reinforced Mortar Concrete?
Relevant answer
Answer
Dear Ferhat,
your idea about mortar I think isn’t correct.
Worldwide you can find ,easily ,on the market structural repair mortars (R4 class EN 1504) with very high performances (Flexural strength over 10 MPa and Compressive over 70 MPa, E-module more than 20GPa and adhesion bonding strength more than 2 MPa ).
Maybe you are speaking about plasters that are mortars and can be based on lime only, lime and pozzolanic materials, lime - gypsum or lime - Portland cement.
The presence of coarse gravel is typical of concrete while isn’t used in mortars, because even for high thickness repair, are used only sand and coarse sand till very fine.
The choice between concrete and mortars depends on the specific application and depending on size. There are several categories for mortars and concretes too.

I read the following passage in a book:
"The detection of surfactants on fabrics requires extraction of the surfactants
from the fabric sample. First, agitate a fabric sample in water at a low liquor
ratio (<1 : 20) overnight at room temperature, then remove the sample and
concentrate the solution containing surfactants for testing using the following
methods at room temperature..."
What do they mean by "liquor ratio"?
Relevant answer
Answer
It is known as material liquor ratio MLR. When any wet processing is done in the textile industry fiber/yarn or fabric is worked/agitated in a volume of liquid. This has to be taken as a ratio; all additives (dyes/ auxiliaries /chemicals) that have to be added for the process will be based on the MLR.
In the text quoted, it reads that the ratio is (less than) 1: 20 which means 1kg of material requires 20 liters of water/liquid.

I assume you mean a flatwork ironer in a laundry for the finishing:
usually you have steam heated or oil/gas heated flatwork ironer (all over type of energy are too expensive).
mostly we speak about working wight (between 1,60 m and 4,00 m, but it exists also until 8,00 m) Roller diameters are usually between 20 cm and 80, but can exist until cm 200 cm.
flatwork ironer have usually between 2 and 3 rolls, depending on what should be stirred. But in big laundries, there can be more.
ironing cloth material used for the roll are Nomex, polyester/needle felt or simply polyester. Important is the layer between the cloth and the roll (in order to press enough).
temperature depends on the fabric which should be stirred cotton above 200°C and PE under 180°C. But humidity of the fabric is also an important factor.
the capacity depends on the dimension of the flatwork ironer and can go up to 200 kg/hour.
only flat linen will be ironed on a flatwork ironer (table linen, bed linen). But you have specialities for towels and particulary to fold the towels or the napkins.

Answer
Hi Nahida,
sorry for the delay here, I was travelling a lot and couldnt find the time to reply to you, I hope I am not too late.
The attached paper already gives you quite a nice overview about what you have to do: You want to determine the surface tension of your liquid and the surface free energy of your textile. Surface Free Energy is the surface tension of solids.
In your case, a force based method is recommended. For surface tension you can measure as stated in the paper with the Wilhelmy Plate method. This is the easiest and quickest method for determining the surface tension with a force based method. If you do not have cationic surfactants, the Plate is the way to go.
The surface free energy of your textiles, you can determine with the so called Washburn method (here are some further information: https://www.kruss-scientific.com/services/education-theory/glossary/washburn-method/). For this method, you take your textile into a special holder, bring it in contact with the liquids and see, how quickly the mass increases over time due to the absorption of the liquid. This gives you information about contact angles and from this, you can calculate the surface free energy.
What is really important for you to know: In the attached paper, they used the Equation of State model. This model, I would not recommend anymore. Nowadays, the main model is OWRK. OWRK splits the total surface free energy into polar and non-polar parts. This is important knowledge, because when you bring in contact a liquid and a solid for adhesion, the non-polar parts of liquid and solid interact and the polar parts. Total values do not help you, because the polar/nonpolar ratio might be completely different. With OWRK you get both parts of your textile, when you do the Washburn method. For the Liquid, you can also determine polar/liquid parts with a Force Tensiometer.
I hope, this helps you. Please feel free to contact me again in case, you have any questions. My mail adress is y.akil@kruss.de if you want to discuss further

Salts plays important role in reactive dyeing by improving the affinity of the dyestuff towards the fibre and acceleration of the dyestuff’s association and lowering its solubility. Normally, Glauber’s salt or common salt/ vacuum salt is used for this purpose.
Is there any salt reducing agent is used for reducing the use of gluber salt?
Relevant answer
Answer
It is possible, but it will be more cost for factory, there is also the risk of having a difficult uniformity of the dyeing and a variation in wash fastness.

Why sustainable clothing movement is working too slowly?
Relevant answer
Answer
Hello Dr. Shrikaant Kulkarni ,
It is time for textile and fashion industry to adopt bricolage as part of a new and sustainable business model.
As a matter of fact, it is time for textile industrie to reconsider the way it uses the raw materials.
Sustainable clothing movement should be considered more seriously; not in "words" but by taking action to "Save Our Planet".

Its common in the textile indurstry to give modulus of cord material by force and related elongation e.g. M-45N= 9% . By that a specific curve is given for each cord material.
But how can i calculate the elastic modulus of the specific cord e.g. 110 tex 1x2 PET in N/mm² ?
I did the reduction of the function of to the curve of the material test data to get the maximum of the increase. Now im struggeling to get the N/mm² ..
Is there a possibility to calculate it ?
Thank you in advance for any help!
Relevant answer
Answer
I agree with Gerald Smith: for calculation of elastic modulus of your tire material ,
it is enough to calculate (45 N/A)/0,09
where A is a cross section area of cord
PS: particularly, for "rigid" cord 2L30NT we have E = 97,4 GPa
for "soft" cord 35-ADY-P we have E = 2,425 GPa

For polymer film samples, if reflectivity and transmissivity in the mid-infrared region (here, 4 to 16 micrometers) are desired, and using a FTIR & ATR spectrometer (Bomem MB Serie Hartmann & Braun) :
1-Is it possible to use the output spectrum to evaluate the reflectivity and transmissivity?
2-Should not the baseline be corrected by OMNIC Software? Using normalize scale is not allowed?
3-If there are more than 100% reflection in some cases, what corrections should be made? Thanks*
Relevant answer
Answer
Even better, there are programs available with which you can analyze your spectra. E.g RefFIT by Alexey Kuzmenko (https://reffit.ch/) or CODE by Wolfgang Theiss (https://www.wtheiss.com/). Both have good manuals. Also SpIRIT by Konstantin Shportko (http://www.shportko.com/spirit.html) should be up to the task.

Hi,
I tried to model a confined stub column using fibre reinforced cementitious composite in ABAQUS. I modelled concrete core as plain concrete with circular cross section(150mm dia & 300mm high). The confining layer was modelled with a total thickness of 8mm on the circumference to the full height with 5mm mesh fibre textile embedded as wire element. CDP model was uswd for both concrete core and confining mortar layer.
After analysis, the longitudinal fibres got stressed due to axial sress, but the fibres in the hoop direction remains unstressed.
Can anyone suggest me a solution?
The results seems like there is no expansion in the hop direction.
...
Relevant answer
Answer
You need a constitutive model to interpret the post-cracking behavior of SFRC. This is what ABAQUS will use to get the correct response of the concrete. You can look for Lok and Xiao (1999) or any other constitutive model

I would like to know which is the recommended method and instruments for textile surface characteristics measurement (surface topography like roughness and overall characteristics).
Relevant answer
Answer
Dear Martinia Ira Glogar,
If you want to measure the roughness on a single textile filament than AFM is the right solution. So you can measure 0.1x0.1mm (a very small spot....)
If you want to measure the overall surface texture an optical method is much better suitable. I suggest focus varition as a suitable tech. With this you can measure also several mm to get a good over view of the textile surfac.

My current week research is about textiles and new technologies (clothes, installations, performance art) so, I'm looking for examples and opinions about art and sciences applications.
Relevant answer
Answer
Dear Colleague Bahéra Oujlakh
Of course we can link art to science. My whole research has been related to this.
I am a liaison between the sciences and the English Department at the University of Arizona. One big area of overlap in literature is science fiction. By that I mean the more cognitively challenging science fiction such as that of H. G. Wells, Isaac Asimov, Jules Verne, Stanislaw Lem, Karel Capek, Kurd Lasswitz, Josef Nsevadba, Octavia Butler, Joanna Russ, Ray Bradbury, Ursula LeGuin and so on.
For instance when in Tucson our university was the planner of the 2007 Phoenix Mars Lander Mission, the dance department gave a concert called Mars and Other Stories.
I just posted a new update in mu Rhetorical Analysis project called "How SF got its Ghetto." It is important to understand the socio-economic-political aspects of knowledge creation of all kinds since as the cliche goes, everything connects to everything.
