The sample atm secured in a paraffin base, which had a small effect on the comber noil pattern. Fiber qualities of materials used in this study, including fiber length and properties illustrative of the fiber nomenclature, were consistent with those previously reported for greige cotton, gin motes, and comber noils [ 21 ].

After analysis, a visual observation of the containers revealed all samples were white; there was no discoloration or scorching.

ASTM D – 99 Standard Guide for Evaluating Nonwoven Fabrics

The increased swelling and relatively constant value for water uptake shown in Figure 2 can be contrasted with absorbency properties, as shown for the cotton blends in Table 3. Empty sample bottles were weighed and then filled with 1 g samples and reweighed. This standard is also available to be included in Standards Subscriptions.

These two properties moisture uptake and swelling promote fluid transport. The gin motes have lower density and higher surface area and thus promote hydrophilic transport of water in the fabric.

All weight loss is attributed to moisture. Each blend was formulated directly in the glass KFT vials by weight basis.

ASTM D 1117

Balanced material surface polarity, swelling, density, and moisture uptake is key to optimizing absorbent nonwovens for use aastm hygiene, incontinence, and even wound care applications, and the results of this study illustrate how these properties may be tuned in with cotton by products used in combination with greige cotton lint.

Two different measures of moisture uptake are also reported.

Results and discussion 3. Need d11117 than one copy? The cotton ginning by-products are used in numerous applications [ 4 – 9 ]. The electrokinetic data presented in Figure 2 includes samples of the cotton blends investigated in this study.

Here we contrast cotton by-product blends in greige cotton nonwovens with a similar previous study where polyester was blended with precleaned greige cotton lint Fabric absorbency measurements 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.

Figure 1 diagrams the process of hydroentanglement. Observation of this phenomenon is based on more accessible water binding sites, i. A sample of bleached cotton prepared by similar process was not available for the testing. A quantity of cotton gin mote fibers was also obtained from T.

As the voice of the U. A peak width at half maximum height of 1. The system is equipped with one low water pressure jet head that wets the incoming feed web material on its top face, while two high water pressure jet heads alternatively impact the wetted substrate on either face. Water absorbency tests were also conducted. Also shown is a calculated pattern for the modified crystal structure of Nishiyama et al.


From this state, further water sorption then assumes the character astj a capillary-like condensation and has been characterized as free water, i. You can download and open this file to your own computer satm DRM prevents opening this file on another computer, including a networked server.

Absorbent applications Highly cleaned greige cotton fiber retains most of its natural, native protective membrane or surface coating of waxes and pectin native to the greige cotton fiber.


The X-ray diffraction patterns for the individual gin motes, comber noils, and greige cotton UCC are shown in Figure 4. We compare properties of the nonwoven fabrics made with precleaned greige cotton that were blended in different proportions with cotton gin motes and comber noils.

Subscription pricing is determined by: It further demonstrates the merit of focusing on material construction and analysis of fiber surface properties with novel by-product fibers at solid-liquid interfaces and the value of considering the molecular factors that influence properties of wettability and fluid transport as they exist in topsheet and layer components useful in absorbent prototypes, i.

We have no document history for this standard. Because KFT is specific to water and is carried out under nitrogen, oxidation is eliminated. How to cite and reference Link to this chapter Copy to clipboard.
