This matched the understanding of the designer’s pattern complexity. The selection of weave architecture depends on the end use of 3D fabrics and 3D structures, and their required performance criteria. The crack density of braided yarn cracks and interface cracks was measured during fatigue loading, as well as the stiffness degradation. This website is compliant with GDPR for individuals located in the European Union. There is no standard method to subjectively evaluate a pattern’s complexity and its content in textile design. The UC of a twill-weave fabric is shown in Fig. Theoretically, only the color effect would affect the computation results compared to the calculation results of DOWP. 3.24). 6.15. As shown in Fig. From Table 6.2(a), we can make a comparison for the four types of pattern, as shown in Figs 6.7 to 6.12. From Figs 6.10 to 6.12, it is seen that there were three pairs of misplacements for ISWP. By comparison, the regular satin weaves such as the eight-shaft (Fig. This method could be used as an evaluation measure to compare the interlacing times at this point. Here, the texture represents the whole appearance or motif perceived by a human. From the explanation given by the algorithm, this operation would result in a different distribution of pixels in the grayscale, which made the lack of comparison of the computation results inevitable. The 4HS exhibited a slightly higher shear load because of its tighter weave pattern in comparison with 8HS, but because both fabrics have a very loose structure, there is much less difference between the two satin weaves compared with the PW. Satin weave is one in which each warp yarn floats over four filling yarns (4/1) and interlaces with the fifth filling yarn with a progression of interlacings by two to the right or the left. Gagel, Fiedler, and Schulte (2006a, 2006b) investigated tension–compression fatigue of a non-crimp glass fabric/epoxy composite. 3.18 shows the normalized behavior of the fabrics. That is, the total shear load is related to the summation of the compaction and the friction at each crossover. Clearly, there were no essential changes of the pattern for human perception, but different times of zoom in or out may have a great influence on the computation results, just like the misplacement of 11 and 12, 4 and 5, and 2 and 3, as shown in Figs 6.13 and 6.14. 6.9b. The warp yarn is 2-ply 150 denier/ply in both cases. The material was a glass fibre multilayer knit in an epoxy resin, and tension/compression–torsion tests were performed on a standardized tubular test specimen. Comparing computation results of ISWP and RSWP with DOWP for SWEP and JFEP. ORGANIC LOTUS SILK, 4/1 SATIN WEAVE #13 (164gsm), per 5 meters SKU: $175.00. The fibre type is the carbon fibre T300J 3K. Pattern complexity order of Fu,ve calculation results. It’s this reason why the front is smooth and the reverse of a satin fabric … In general, we do not sell, trade, rent or otherwise share your Personal Information with third parties without your consent. Twill yarns, with patterns such as 2/2 or 4/4, could interlace after crossing every two or more strands of transverse yarn. According to human perception, sample 7 had a much finer texture than sample 1, although from the textile design viewpoint the former pattern was more complex than the latter. A satin weave will always be: Over X, Under 1. Mechanistic progressive damage models are based on the effective damage mechanisms that drive the fatigue damage. After this, we did another experiment to set the pattern complexity order. To better understand the quantitative relationships amongst the weave patterns, the number of crossovers (Table 3.4) within the tested area (182.3 cm2) is examined. Sep 13, 2015 - This Pin was discovered by kat diuguid. For example, in Fig. For designers, DOWP is the basic foundation of fabric structure. Stiffness degradation and evolution of the ±45° and 90° crack densities were monitored. The matching condition extent of the Fu,vi computation result was between the Fu,vh method and the Fu,ve method as shown in Table 6.4. With regards to RSWP, so many factors will influence the final appearance, such as internal force interaction, yarn float and shift, fabric density, yarn parameter, compositions, weaving machine parameter, etc. This suggests that in the friction-dominated portion of the shear deformation, the resistance does correlate with the number of crossovers. Example of satin and sateen weaves: (A) R = 5, Se = 3 satin weave and (B) R = 5, Sp = 3 sateen weave. The direction the shift number is applied is indicated by subscript e (for warp direction) or p (for weft direction). The comparison orders are shown in Figs 6.10 to 6.12. 9.43. Fig A is a basic 5 end, 4/1 satin weave, warp float facing. 3.17 were normalized with respect to the number of crossovers for each fabric type. Satin and sateen weaves are lustrous and smooth, which are mainly used for lining or pajama design. Comparison between computation result for DOWP and human perception for TWEP. This weave structure is called an (N + 1)-harness satin weave. The warp yarn consists very often of fine silk or worsted while the weft may be an inferior yarn. 4 harness satin weave. However, the best condition for integration is the one with the least bending angles. 6.10. This type of weave is specified by the repeat size (R) and shift number (S). If the position of the pattern to compare had the same relative position in the DOWP, its misplacement extent value was defined as 0. The higher load was most likely caused by the effect of density of crossovers on the yarn compaction. Typically fabrics made from satins have a smooth and lustrous appearance. It has a long chain structure with limited branching, resulting in a low viscosity and a faster crystallization than for the strongly branched polymers. The processing temperature is critical when using a thermoplastic matrix material. 6.5. 4.17 shows a satin and a sateen with R = 5, Se = 3 for satin and R = 5, Sp = 3 for sateen. Unavailable per item 100% Lotus Fiber. That means, that a higher fiber volume percentage can be achieved from orthogonal weave architecture; however, the disadvantage is that the whole structure falls apart if the Z fibers break. In contrast, for the satin weaves, the crossovers are isolated, with neighboring sections that allow ease of expansion and movement of the fibers when compaction occurs at the local crossover (Liu, 2005). 6.7. 6.8. Fiber damage during weaving is less likely because there are no interlacements. 3/1 Stain Weave (4-shed) Suitable for multipurpose. For PWEP, the order is [7, 1, 11, 12]; for TWEP, SWEP and JFEP, the corresponding order is [6, 5, 4, 9, 8], [3, 2, 13] and [10, 14] respectively. The weaving pattern is a five-harness satin weave with a mass per surface unit of 286 g/m2. PPS is a semi-crystalline thermoplastic, which means that the amorphous and the crystalline phases coexist. Table 6.3. The proportion between both phases is determined by the preceding temperature cycle. Both plots in Fig. Actually, the pattern complexity should be defined by using different viewpoints in different design procedures. Both plots in Fig. The major damage mechanisms of transverse yarn cracking, inter-yarn debonding and delamination were modelled with simple mechanistic models. We need to note that the yarn color effects might make the reference of limited use in ISWP. In Figs 6.10, 6.11 and 6.12, the misplacement extent was quite significant except for two samples of JFEP. They are not true satins as there are adjacent binding points (see Figs 6.53 and 6.54). These fabrics do not exhibit the undulations (crimp) that are present in woven fabrics, and thus, composites made from the non-crimp unidirectional fabrics will have essentially straight-line yarn paths. In the real scanned image, there were a lot of factors which may be regarded as noise affecting the final calculation results. 4/1 Satin Weave. For the 4HS and 8HS with their looser weave patterns, the rapid rise from the locking angle effect does not occur until about 30° and 40°, respectively. Melting starts at a temperature of 280 °C, the material is completely liquid at 300 °C. 11 and no. 6.9. As described in Section 3.1.2, there are many different weave patterns [e.g., PW, twill weave (TW), and satin weave (4HS, 8HS)] with different degrees of tightness and with balanced vs unbalanced warp and fill yarns. In PW fabrics, the warp and fill yarns have the most undulation, as well as restriction; therefore, there is a very small gap in between the yarns. This state of slightly altered viscosity lasts until the material starts to crystallize at 120 °C.
