Coordinate-Parametric Matrix Model Inspired Square-Conjoint Pattern in Cross Woven for Conventional Bamboo Mat

“…In this study, if the weft is pushed above the non-dyed warp strips to regard as a positive pattern, other than if the colored strip is pressed below the non-dyed strip it regards as a negative pattern. To rapidly capture pictorial information of woven patterns, a recognition of colour design on the bamboo mat is defined as the black-and-white grid pictures, which is analogous to a binary image matrix division construct [35,36,41].…”

“…4 Perform a Parametric Simulation Modeled with GH to the Weaving Pattern of SCPCW 4.1 Coordinate-Parametric Transformation Logic of SCPCW Especially, the weaving logic of the coordinated matrix is referred to apply in the computing component of GH software, which is realized to predict the micro-weaving structure and weaving effect in the bamboo mat. First, the bamboo-mat pattern is segmented to the binary image, similar to when a jacquard fabric's pattern matrix [34][35][36]43]. In fact, the Image Sampler component of GH could recognize the coordinate information of the SCPCW in the bamboo mat, which could recognize the array output of the jacquard pattern oppositely from the textile-information identification.…”

“…Compared to bamboo weaving and jacquard fabric, the image information is likewise digitalized to realize the freely desired effects. Namely, the matrix coordinate of the bamboo mat pattern is similar to the digital weaving software of the jacquard fabric [34][35][36]. Subsequently, the gradients of the weaving units in the bamboo-mat description can be adjusted and regulated for some weaving textures in various patterns [27,28,37].…”

Research on the virtual display of a weft-knitted seamless kneepad based on the free-form deformation model

“…As shown in Figure 1(a), we selected part of the loop on the kneepad fabric for photo sampling. On the premise of maintaining the shape of the loop, based on the research of the knitting loop model by related scholars, 12,15 we select eight points as the value points of the knitted loop structure.…”

Structure modeling in three-dimensional simulation of weft-knitted seamless kneepads

“…As shown in Figure 4(a), on the premise that the loop shape can be maintained, we take eight points as the characteristic points of the knit loop structure based on related research on the knitting loop model. 3,19 The real fabric was knitted by a ZY550HS automatic jacquard kneepad machine, as shown in Figure 3 and Table 1 (Zuoyou Knitting Goods Co., Ltd, China, Wuxi). The ZY550HS machine specializes in the production of sports, medical, health knitted kneepads, elbow pads, and other equipment, with seamless, jacquard functions.…”
