Here we contrast cotton by-product blends in greige cotton nonwovens with a similar previous study where polyester was d1171 with precleaned greige cotton lint The polyester water content value is consistent with r1117 found in literature of fiber at standard testing conditions, around 0.

Water absorbency tests were also conducted. A quantity of cotton gin mote fibers was also obtained from T. The swelling behavior of the incontinence products is measured using the Anton Paar analyzer with the cylindrical cell template.

These two properties moisture uptake and swelling promote fluid transport. The blended nonwoven materials possess absorbent properties characterized by similar moisture uptake 7.

However, limited use of cotton gin motes is made in traditional textiles made with spun d111. The water content in the blank vial was 0.

Each blend was formulated directly in the glass KFT vials d117 weight basis.

Our readership spans scientists, professors, researchers, librarians, and students, as well as business professionals. 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 enter defective regions in the crystallites formed during drying.

Edited by Matheus Poletto. In addition, the processing innovations of modern nonwovens provide a facile conduit for efficiently blending these types of discounted by-products with greige cotton lint to explore new, value-added cotton-blend nonwoven products.

Crystallinity index and crystallite size of the different fibers.

The nonwoven hydroentanglement of greige cotton lint with cotton gin motes and comber noils blends was analyzed for fiber surface polarity, swelling, and absorbance to assess properties with potential usefulness in absorbent nonwovens. The AATCC drop test measures the time it takes for one drop of water applied to a fabric held in an embroidery hoop to be absorbed when the sheen disappears. Observation of this phenomenon is based on more accessible water binding sites, asfm.

Thus, it is demonstrated that the use of less expensive cotton gin motes—the by-product of cotton ginning process—in blends with cleaned greige cotton lint asm potentially be useful and competitive for many nonwoven end-use products where absorbency or moisture uptake, swelling, biodegradability, and sustainability are desirable. Thus, an increased capacity to hold water is observed as well in the astj higher absorption capacity of the cotton by-product nonwovens, which have smaller cellulose crystallite size than the greige cotton Table 4.

The cotton ginning by-products are used in numerous applications [ 4 – 9 ]. These test methods cover procedures for testing nonwoven fabrics. It is the responsibility of ashm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The calculated pattern matches the observed patterns [ 28 ], especially that of the gin motes, fairly aatm despite the lack of any consideration of amorphous material in the calculation. The gin motes have lower density and higher surface area and thus promote hydrophilic transport of water in the fabric. Your Alert Profile lists the documents that will be monitored.

ASTM D—standard test method for water in lint cotton by oven evaporation combined with volumetric Karl Fischer titration. The modification involved using an infrared lamp to dry the materials rather than a laboratory oven as called for in the standard methods. Need more than one copy?

Results and discussion 3. Empty sample bottles were weighed and then filled with 1 g samples and reweighed.
