Abstract


Flat silk yarn is made by a special technology, rich colors, flash effect, has good auxiliary the wearability and unique decorative effect, it not only has a good look expressive fabric fully reflect the popular qualities, and rich varieties of textiles to meet the individual needs of the textiles growing. The flat silk weaving prone to the following question: flat yarn for weft unwinding inevitably will produce natural twisting phenomenon, caused by the parallels can not be flat woven into the fabric gloss, feel. Second, the flat wire easily tensile elongation thinning finishing the fabric by weaving system can obviously see the fabric luster uneven and is stretched thinner yarn segment surface color will come off causing streaky, chromatic aberration serious and even decapitated, to the appearance of fabric have serious repercussions. Third, the yarn is flat flakes and a smooth surface, weaving weft insertion difficulties, use ordinary Sword head In the weft handover, easy grip is not strong parallels slippage from the sword head phenomenon. This paper to address the problem, consult the relevant literature, and learned that there is no system of class the fabric weft insertion technology research reports. Therefore, in order to provide a theoretical basis to the actual production and theoretical studies of the subject to the flat yarn and fabric for the main object of study and the study from the following aspects: (1) YG061 electronic yarn strength tester flat wire Tensile properties, elastic properties of the test results show that: the rupture strength of the flat wire is not high, and the elongation at break is much higher than other conventional yarn, initial modulus, elastic recovery performance generally. This shows that a flat yarn having a good elongation and softness, but such a small force under the high elongation for textile purposes, weaving yarn easily been stretched thinner deformed, to the fabric appearance serious the impact. In addition, analysis of the specifications of the flat yarn that the width of the flat wire, thickness, the influence of the line density on the yield strength and the elastic recovery rate and proven specification parameters and the relationship of these two performance metrics. (2) for the natural flat wire unwinding twisting problem, in this article from the flat wire transmission line improvements, research and analysis of the weft unwinding device. The unwinding of the flat yarn by retrofitting weft unwinding device to reduce flat yarn unwound generated twist. For weaving yarn easy tensile deformation, the head sword flat silk weaving and weft tension for research and analysis. One hand, the analysis of the rapier head of the flat yarn and the distinction between ordinary rapier head, the rapier head and the existing flat yarn design improvements; the other hand, the determination of the flat yarn weft insertion tension, combined with the mechanical properties of the flat yarn were analyzed, proven suitable for weaving flat wire specifications. (3) flat wire unwinding the natural twisting, weaving fabric surface flat wire convolution. Flat wire formed the fabric surface convolutions point effect evaluation of flat wire the convolution test method at the surface of the fabric, and to demonstrate the feasibility of this test method, experimental proof: after weaving weft unwinding device made flat smooth surface of silk fabrics, transfer music points reduced by about 80%. (4) on the gloss and surface friction properties of the flat silk fabrics were tested, by using the The weft unwinding device and without weft unwinding device woven made of two fabric weaving effect seen: weft unwinding device woven made of fabric, the surface is reflected light more concentrated light, strong luster; feel more smooth surface than the leveling. (5) in the on the basis of pre weft insertion technology research, product design and development, combined with a unique style flat wire flash pattern design with the organizational design and development of weft arrangement than 1:1 weft double flat silk jacquard fabrics. By bright polyester twisted yarn with bright polyester Moso bamboo wire, flat wire intertwined, giving the product a unique look.
