How To Solve The "Aurora" Phenomenon In The Fabric Containing Fur Uniforms
At present, there is no specific research on Aurora problem of woolen fabrics at home and abroad, but it has the influence on the aurora phenomenon of pure polyester fabric and combed wool and the cause analysis of P. In this paper, the mechanism of Aurora phenomenon in the process of wearing polyester and 70/30 blended military uniform is discussed, and some simple and feasible Aurora eliminating methods are sought. < /p >
< p > by means of fiber analysis, fabric thickness measurement, fabric structure analysis and electron microscope observation, it is found that the fiber scales on the aurora are worn, and the longitudinal surface morphology of polyester fibers is less. Therefore, it can be thought that the cuticle layer on the surface of wool fibers is partly worn out due to external forces such as friction, which makes the scales angular blunt, highly reduced, smooth in surface, and easy to focus on reflecting light. < /p >
< p > the fabric of aurora is significantly thinner than that of the non auroral fabric. The thickness changes indicate that the Qu Bo or structural phase of the yarn may change, or it may be the change of the fiber shape or the decrease of the gap between the fibers. Through the analysis of fabric structure, because the twill weave fabric has a twill line on the surface of warp or weft yarn, the fabric has a prominent texture along the slant direction. Its luster is not strong, but its luster is displayed under a little external force. < /p >
< p > the satin weave fabric has obvious longitude and latitude floating length, and its organization intersection point is the least. Because the single organization point is mostly covered by the floating long line, the fabric has smooth appearance and bright luster. Plain weave weave weft and weft interweave more times. The yarn is flexed and the fabric surface is uneven. It increases the intensity of diffuse reflection and does not appear Aurora easily. Therefore, different tissue structure and different fabric composition will have different effects on the fabric aurora. < /p >

With the immersion time increasing, Aurora gradually improves. After 1 hours, the aurora is completely eliminated, but the fabric aurora is weaker than 1 hours. The samples treated with glacial acetic acid, compared with far Aurora cloth samples and treated fabrics, showed that Aurora phenomenon was obviously improved and almost completely eliminated. After 2% diluted ammonia solution, the aurora effect was not obvious. After 3% diluted ammonia solution, the partial Aurora was eliminated, but most Aurora still existed. After 4% diluted ammonia water treatment, the majority of Aurora was eliminated, and after 5% diluted ammonia water treatment, the Aurora was completely eliminated. However, because ammonia is weakly acidic, it is prone to volatilization and overflow of ammonia. It has strong pungent odor, corrosive and tear like properties. Taking into account the above factors, ammonia is not suitable for making matting agents. < /p >
< p > above all, through the test of the fiber, yarn and fabric properties of the sample, the analysis of the structure, the comparison of the test results between the aurora and the aurora fabric, and the analysis of the scanning electron microscope pictures, it is concluded that the wool and polyester military uniforms are frequently subjected to friction and pressure during the wearing process, causing the fabric to flattening, flattening, and the damage of the wool scales to a certain extent, which is the main reason for the aurora. < /p >
< p > in addition, dust and pollutants penetrate into the fibers or between yarns, so that the a href= "http://www.91se91.com/business/" > fabric < /a > surface is compacted, which is also the cause of Aurora. By using acetic acid, citric acid, glacial acetic acid and dilute ammonia solution to improve the aurora phenomenon of fabrics, it is found that citric acid is a good Aurora eliminating material, and it is cheap and has wide sources and does not produce exciting odor. Proper amount of glacial acetic acid can improve the softness and luster of the fiber, and is a better matting material. < /p >
