Amorphous Bimetallic Nanowires with High-Performance Microwave Absorption: A Case for FeCo Nanowires
Junyao Shen,Yongtao Yao,Yanju Liu,Jinsong Leng 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2019 NANO Vol.14 No.4
Amorphous FeCo nanowires (NWs) with the average diameter of 120 nm were successfully prepared with a magnetic-field-assisted (MFA) hydrothermal method. Rapid reaction time was adopted to obtain amorphous FeCo NWs, being checked by XRD and TEM. Tuning the stoichiometric ratio of Fe/Co content meets the optimal impedance matching under different absorption frequency, making both improved intensities and frequency ranges of microwave absorption. For example, under 3mm coating thickness, the reflection loss (RL) peaks of Fe3Co7, Fe5Co5 and Fe7Co3 NWs are -25.88 dB at 4 GHz, -19.06 dB at 4.24 GHz and -21.98 dB at 5.44 GHz. The related efficient absorption bandwidths (fE < -10 dB) of Fe3Co7 NWs, Fe5Co5 NWs and Fe7Co3 NWs are 5.40 GHz, 3.52 GHz and 4.91GHz, respectively. It is ascribed to integrating enhanced dielectric/conductive losses, negligible damages from eddy current effect and good impedance matching for high-performance FeCo NWs absorbers. This work paves a new path on synthesizing bimetallic wire-like nanostructures for microwave absorption demands.

The Influence of Moisture Content on Shrinkage of Wool Fabrics during Domestic Tumble Drying Process
Wei Bao,Jinsong Shen,Xuemei Ding 한국섬유공학회 2021 Fibers and polymers Vol.22 No.2
Shrinkage of wool fabrics caused during tumble drying is a serious defect. In the drying process, the feltingshrinkage of wool fabrics was influenced by the moisture content and temperature of wool fabric as well as mechanical actionbeing applied on the wool fabric. In the current study, the relationship between moisture content of wool fabrics andshrinkage was studied in the drying programs under no heating condition or heated condition. This study also analyzedshrinkage behaviors of the untreated wool fabric and the Chlorine-Hercosett treated wool fabric with different moisturecontents. For the untreated wool fabric, moisture content in the fabric could influence the mechanical properties of woolfibers, resulting in the different extent of felting shrinkage of wool fabric during tumble drying. For the Chlorine-Hercosetttreated wool fabric at different initial moisture contents, there was no obvious variation in the length change under no heatingcondition, but a slight difference in the shrinkage under heated condition. The study could lead to the new guidance forefficient drying of wool fabric with less felting shrinkage.

3D Printing Based on Material Extrusion to Create Surface Patterns on Textile Fabrics
Randa Alsabhi,Angela Davies,Guy Bingham,Jinsong Shen 한국섬유공학회 2023 Fibers and polymers Vol.24 No.11
3D printing technology has been developing rapidly in recent years. This technology is extensively used for producing prototypes of products and their designs with a wide range of materials in the manufacturing industry. The Fused Deposition Modelling (FDM) process uses the extrusion of molten thermoplastic materials through heated printing nozzle to create design objects layer by layer. The current research was to develop 3D printing technology on textile fabrics to create surface design based on FDM process using the Ultimake 3D printer. Printing parameters play an important role for printing on fabrics specially to achieve strong adhesion between the printed patterns and the surface of the fabrics. This research developed a method for assessing the attachment strength in the interface between the printed objects and the surface of fabrics. The effect of the initial setting distance between the printing nozzle and the printing platform on the performance of 3D printed fabrics was investigated. The research work demonstrated the ability to create different design patterns in 3D on the fabrics with excellent durability to washing, which shows potential for the commercial application in fashion industry.
