“…16,17 It has already been reported that the production of acrylic fibers is possible with several physical and chemical modifications for various end uses. 18,19 Nevertheless, applying chemicals to modify the fiber properties is not free of environmental pollutions and impact on public health. 18,20 For example, different types of hazardous and toxic chemicals, consisting of halogen, phosphorus, or sulfur are used to increase the flame retardant property of the PAN fibers.…”

The composite alpaca/acrylic fibers were auspiciously produced through a wet spinning technique to reduce the consumption of petroleum-based polyacrylonitrile (PAN) and to enhance the thermal stability and moisture properties of the fibers. The waste alpaca fibers were converted into powder using a mechanical milling method without applying any chemicals. Alpaca powders were then blended with the PAN dope solution in different weight ratios of alpaca: PAN (10:90, 20:80, and 30:70) to wet spin the composite fibers. The Fourier transform infrared spectroscopy showed that all the composite fibers possess the functional groups of both alpaca and PAN. The nuclear magnetic resonance spectroscopy confirmed the presence of typical carbonyl carbon (C O) and nitrile carbon (C≡N) peaks of protein and PAN, respectively. The differential scanning calorimetry and thermogravimetric analysis revealed the enhanced thermal stability of alpaca/PAN composite fibers. The moisture properties of the composite fibers were subsequently found to increase with the incorporation of alpaca, more than three times that of pure PAN fibers. These results revealed a potential green pathway to producing composite acrylic fibers with improved thermal and moisture properties by applying textile waste materials.

“…From Table 2, the contact angle values of the treated fibers were generally found to be slightly decreased while some remained unchanged. This reduction in contact angle meant that the liquid would spread more freely on the fiber surface and hence would help to improve the wettability of the fiber [19]. It was established that LTP modification of fibers resulted in oxidation and degradation of the fiber surfaces [18].…”

“…It was established that LTP modification of fibers resulted in oxidation and degradation of the fiber surfaces [18]. The oxidation creates oxidized functionalities, which lead to an increase in surface energy [20], while degradation mainly changes surface morphology of the fibers [19]. In previous study [18], scanning electron microscopic micrographs had shown that the LTP treatment caused an increase of surface roughness.…”

The wool scale present on the fiber surface gives rise to certain unwanted effects in textile wet processing. The effects, for example, include felting and poor wettability. In the past, the removal of scale was done either by surface modification through physical/chemical degradation of scale or by deposition of a polymer on the scale. In modern treatment, combination of both methods is usually carried out. Since the deposition of a polymer on the fiber surface depends much on the surface characteristics of the fiber, therefore, the required surface property of modified fiber is an important factor for polymer application. On the other hand, the surface modification methods may also result in improved wettability on the surface of fiber. The present study investigated the surface physico-chemical properties of wool fiber subjected to different surface modification treatments. In this study, Soxhlet extracted (dichloromethane extracted) wool fibers (21 µm diameter) were modified by low temperature treatment using different plasma gases, namely oxygen, nitrogen, and 25% hydrogen and 75% nitrogen gas mixture. The study of surface physico-chemical properties included contact angle measurements with different liquids, and determination of critical surface tension and surface free energy. Experimental results showed that these properties were improved after surface modification treatments and the results were quantitatively discussed.

A series of poly(ethylene oxide) (PEO) and nylon-6 copolymers were synthesized through condensation reactions. The rheology of the prepared copolymers was tested using a capillary flow rheometer. The molar mass was investigated by performing basic analyses such as relative viscosity, gel permeation chromatograph, and amino-end group analysis. Their thermal properties were examined by differential scanning calorimetry, and the crystalline structure was determined using wide-angle X-ray diffraction. The results obtained from partially oriented yarn indicated a dramatically conversion from the c form to the a form. Following the draw texture process, the a form dominated all draw textured yarn. Once the segments of PEO were introduced into the nylon-6 backbone, the moisture regain and q max (warm/cool feeling) of the fabrics was enhanced remarkably. The surface resistivity of fabrics improved with increasing PEO content, which is mainly due to water absorption. V C 2012 Wiley Periodicals, Inc. J Appl Polym Sci 126: E206-E217, 2012
