“…As can be seen in Table 1 , the values of F d to d for each sample were 0.094 (0 L/h), 0.099 (15 L/h), 0.102 (30 L/h), and 0.106 (45 L/h) cN/μm, respectively, indicating that C d (air drag) improved with the increased PANI coating amount (polar species). The results further verify that the change of air drag was mainly due to the change of C d [ 39 ].…”

“…Additionally, HCl-doped PANI coating could improve the wettability of substrate significantly due to the N-containing polar species in PANI [ 37 ]. Based on our previous work [ 38 , 39 ], the oxygen- and nitrogen-containing polar groups grafted on the PET yarn surface by plasma mainly caused the rise in air drag through forming H-bonds with the water molecules in the air jet. Taking these into consideration, the PANI coating might also increase the air drag of PET yarn.…”

Abstract:In this paper, a simple method to prepare PANI-coated conductive PET yarn is reported, which involves pre-applying aniline and HCl vapors on PET surface and subsequent dielectric-barrier discharge (DBD) plasma treatment of the coated yarn under atmospheric pressure. The volume resistivity of the optimal sample was about 1.8 × 10 5 times lower than that of the control. Moreover, with the increase of coating amount of PANI, the air drag of PET yarns improved gradually. The surface chemistry of the treated yarn was analyzed by Fourier transform-infrared (FT-IR) spectroscopy and X-ray photoelectron spectroscopy (XPS), while the morphology was observed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). This study offers a new method to prepare conductive fabric via air-jet loom and is expected to increase the weaving efficiency of air-jet loom.

XPS and ATR‐FTIR study on chemical modifications of cold atmospheric plasma (CAP) operated in air on the amino acids L‐proline and trans‐4‐Hydroxy‐l‐proline

Amino acids L-proline and trans-4-Hydroxy-L-proline were exposed to cold atmospheric plasma (CAP) generated by dielectric barrier discharge and operated in ambient air at dry conditions. Surface analysis reveals an oxygenation of both amino acids the degree of which is dependent on treatment time. New NO À 3 or NO 2 groups are attached to the surfaces. Proline and hydroxyproline respond differently to the cold atmospheric plasma, proline being more prone to ring opening, fragmentation of the molecule, and attachment of C─OH and CO groups. Aging experiments show that plasma mediated attachment of new functional groups is, to a great degree, reversible over time.

“…In our previous work, we proved experimentally that the grafted polar groups would enhance the air drag. 30 Meanwhile, the grafted polar groups could also lead to the improvement of moisture regain. 31 Therefore, in order to discuss the mechanism of air drag improvement from another perspective, the correlation between the air drag and moisture regain was analyzed.…”

In this paper, atmospheric pressure dielectric barrier discharge (DBD) plasma was used to treat four kinds of chemical fiber yarns, namely polyacrylonitrile (PAN), polyethylene (PE), polypropylene (PP) and polyethylene terephthalate (PET), for which the air drag force, moisture regain and yarn diameter were measured. Compared with untreated samples, the air drags of treated PAN, PE, PP and PET yarns increased maximally by 10.7%, 43.0%, 40.0% and 18.9%, respectively, in the present experiments. A two-way analysis of variance and correlation analysis were performed to study the effect of plasma treatment on air drag and other properties of these four chemical fiber yarns. The combination of X-ray photoelectron spectroscopy analysis and the determination of the DBD plasma component can further enhance the understanding of the difference between DBD plasma treatment processes among these four chemical fiber yarns. This study provided the experimental basis to improve the air-jet weaving efficiency of chemical fiber fabrics.
