ASTM D 1117

The Kett measures moisture weight loss after drying under a large infrared heat lamp which, minimizes scorching. The sample was secured in a paraffin base, which had a small effect on the comber noil pattern.

Also, note that the KFT water content Table 3 for polyester is 0.

You may delete a document from your Alert Profile at any time. We have no document history for this standard. The microstructure of cotton fibers allows the penetration of water, in the case of the greige cotton nonwovens studied here.

Our readership spans scientists, professors, researchers, librarians, and students, as well as business professionals. December 4th Reviewed: Results and discussion 3.

Consideration of the phenomena of water binding to cellulosic fiber, from crystalline to fibrillar state, crystalline cellulose crsytallites of 36 cellulose chains or more has been characterized as low water binding Please first log in with a verified email before subscribing to alerts.

The amphiphilic surface character in nonwoven greige cotton, which is a combination of the polarity balance between the hydrophilic and the hydrophobic elements of the cotton material, is suitable for the application to the material layer components of incontinence absorbent products and wipes [ 10 ].

X-ray diffraction patterns d11117 the three different cotton constituents displayed similar crystalline cellulose compositions.

The results have shown that the cotton gin mote fibers, compared to the polyester fibers, yield improved moisture uptake while giving comparable swelling attributes. As a check, standard oven drying was used on the UC cotton and polyester fibers, generating a moisture content of 7. The Segal Crystallinity Index values arise almost completely from the overlap of the wide observed peaks Embed this code snippet in the HTML of your website to show this chapter. Electrokinetic data for the hydroentangled fabric samples made with the different fibers and their blends.


In combination with surface-exposed cellulose from nonwoven hydroentanglement process conditions, unique fiber properties are retained when compared to scoured and bleached cotton. Measurement of fabric polarity, charge, relative composition, swelling, and porosity Streaming zeta potential experiments are carried out with an electrokinetic analyzer, which is manufactured in Ashland VA, USA, using the cylindrical cell developed for the measurement of fibrous samples.

Absorbency characteristics of the various hydroentangled fabrics. If the document is revised or amended, you will be notified by email. Moisture determinations The water content results via Karl Fischer titration KFTfollowing ASTMtrack the moisture results based on the Kett moisture determination balance that utilizes ashm infrared lamp Table 3.

One method [ 15 ] is simple, portable, easy to use, and involves an infrared lamp to dry the samples. A peak width at half maximum height of 1.

December 9th DOI: All weight loss is attributed to moisture. It is the responsibility of the user of this standard to asm appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The enclosed samples were then placed into mason jars that had been acclimated in the conditioned lab.


The calculated pattern matches the observed patterns [ 28 ], especially that of the gin motes, fairly well despite the lack of any consideration of amorphous material in the calculation.

ASTM D – 01 Standard Guide for Evaluating Nonwoven Fabrics (Withdrawn )

Griege raw cotton gin motes are just one of several by-products viz. The water content in the blank vial was 0. A quantity of cotton gin mote fibers was also obtained from T.

Your Alert Profile lists the documents that will be monitored. These two properties moisture uptake and swelling promote fluid transport. These authors also point out that it is insufficient to use the cellulose crystallinity alone in calculating accessible water surfaces since water molecules can also asrm defective regions in the crystallites formed during drying.

This standard is not included in any packages. The relationship between crystallinity and moisture uptake has received some attention in the literature over the years However, cellulose crystallite size varied. As the voice of the U. The calculated X-ray diffraction pattern is shown in Figure 3. The hydroentangling line e1117 flushed and cleaned after each fabric production trial. The calculated surface-to-volume ratio of smaller cellulose crystallites, as observed with the cotton by-products, is higher than the greige cotton, which infers more accessible hydroxyls for bound water.

Each blend was formulated directly in the glass KFT vials by weight basis. Swell test, k min The water from the cotton sample from the vial is released and driven into the titration cell from which the percentage of moisture present is calculated from the volume of reagent consumed. The fabric production speed was 5 m per minute.
