In the present study, the buckling behavior of delaminated plate in woven fabric composite laminates was studied. For this purpose, at first, the structure of woven fabrics was defined as shape functions. Then, the continuous analysis was used to study the bucking of delaminated plates. Based on the Rayleigh–Ritz method, the related formulations were developed to predict the critical buckling load of composite laminates. Three types of woven fabrics (viz. Plain, Twill, and Satin architecture) were used as reinforcements for polyester composites. The 8-ply laminated composites were fabricated using Vacuum Infusion Process (VIP). The results of buckling test showed that the critical buckling loads of laminates reinforced with Plain, Twill, and Satin woven fabrics are 1.35, 1.12, and 1.48 kN, respectively. Also, the results of analytical method are compared with experimental results and those achieved by the finite element method of analysis using ABAQUS software. Compared with experimental results, the maximum error of analytical and FE models is about 17% and 10%, respectively.

Mattress plays an important role in the quality of human sleep, warp-knitted spacer fabric (WKSF) is a rather important mattress material, this paper explored the indentation state of WKSFs of 20 mm thickness and 0.12, 0.15, 0.18, and 0.25 mm spacer filaments under the action of curved surface pressure by using spherical compression tests and finite element simulations, with the combination of three-dimensional and non-uniform pressure characteristics exerted on the mattress by the human body when lying down. Tests and simulations analysis would be shown in four aspects: firstly, when the spherical indenter acts on the WKSFs, the compressive stress, Indentation Force Deflection (IFD) and support factor (SF) of the WKSFs increase as the spacer filament fineness increases; secondly, the compression depth of WKSFs should be controlled within 40% when used as mattresses to obtain good compression comfort; thirdly, A warp-knitted spacer fabric with a 0.25 mm spacer filament fineness provides both comfort and pressure resistance and better meets the needs of most people for a spacer fabric for mattresses.

In this work, willow fiber was extracted from willow inner bark and modified with alkali solution of various concentrations, temperature and time. The morphology, surface functional group, crystal and thermal stability were investigated by using a scanning electron microscopy, a Fourier transform infrared spectroscopy, an X-ray powder diffractometer, and a simultaneous thermal analyzer, respectively. The acid (H2SO4, 2 ml/l) extraction procedure removed the hemicellulose and part of lignin from willow bark, cleared the aggregation of WB, kept the crystal structure of willow fiber, dramatically increased the crystal length of fiber (from 18.46 to 30.15 nm), and enhanced the onset degradation temperature (from 262.23℃ to 297.62℃) and chemical reactivity (DTG: from 0.57%/s to 0.84%/s). The alkali treatment further removed lignin from willow fiber, smoothed the fiber surface, increased the intensity of cellulose ( I 002 ) from 646 counts to 1292 counts, and lengthened the crystal length from 30.15 to 41.84 nm. Varying the alkali treating condition, the crystal index and thermal stability reached to the climax at 60℃ of treating temperature and 7 h treating time. The treated willow fiber may have potential applications to composite with polymer, and to be used in pharmaceutical field as additives.

Knitted fleece fabrics with superior comfort characteristics are chiefly focused in winter wear. Thermal characteristics are an area of interest in selecting fleece clothing. However, environmental hazards also need to be focused. Fleece clothing is worn in cold areas having higher ultraviolet rays exposures. Hence the clothing should have the capability of combating environmental challenges. The study focuses on engineering variable fleece structures with different materials. Cotton, nylon, and polypropylene fleece patterns have been knitted using fleece 1:1, 3:1, and 2:2 patterns. The designs vary by tuck and miss stitch configurations in the fleece course. Comfort characteristics were determined through air permeability, moisture management, and thermal resistance tests. Performance criteria were evaluated in terms of pilling resistance and ultraviolet protection factor (UPF) investigation. Structures and materials owing better comfort characteristics with satisfactory UPF have been predicted as safe clothing in UV affected zones, that is, fleece 3:1 possessed the optimum comfort characteristics and UPF simultaneously; however, the mechanical performance was better for 2:1 and 1:1 fleece fabric due to less amount of miss stitch floating yarns.

The technology of warp knitting is one of the more recently developed processes in knitting technology. Complex machine technology and highly productive machines characterize the process. This principle allows obtaining fabrics with various characteristics and for various applications. It is possible to insert straight weft yarns in the textile structure. The weft yarn can be inserted either over the entire width of the textile surface, that is, full wefts, or only over a specific area of the textile, that is, partial wefts. However, weft insertion is the limiting factor in respect of process speed, even if different methods for traversing yarn positioning in the textile industry with the potential to increase the weft insertion speed had been introduced. This paper aims to analyze the inlay yarn condition in respect of yarn tension and yarn speed during the cyclical process of the state-of-the-magazine inlay yarn insertion system and, based on these findings to propose a solution to increase the laying velocity by developing a new method. The approach used is to reduce the vibration induced by the reciprocating movement of the guide bar during inlay operation by using a continuous movement of the mobile elements. This will allow in the future increasing the production velocity, to reduce the stress on the inlay yarn due to acceleration and deceleration.

A model about the strength of polyvinyl chloride coated polyester at high temperature was proposed in this paper. The model can predict the warp-direction strength, weft-direction strength, and off-axis strength at high temperatures according to the uniaxial tensile strength in warp direction at room temperature. In this paper, the strength model of coated fabric membrane bearing biaxial tension was established by off-axis tensile test. Next, the strength of weld joints of coated fabric membrane at normal and high temperature were compared. Then, a strength predicting method for symmetric and asymmetric weld joints at high temperatures was proposed. Finally, the relation between temperature and fracture energy of weld seam was proposed.

Ultrasonic welding is a universal, clean, and secure alternative joining method. Alternative joining technologies are used increasingly to fulfill specific functional requirements of the seam, such as fluid impermeability to achieve positive bonding during the assembly of technical textiles. In this research, the effect of important ultrasonic welding parameters on peel strength and weld seam thickness was investigated for flexible and lightweight textile material, which is a valuable innovative hybrid textile for technical applications like architectural, construction, and protective textiles. Three main welding parameters with three different levels were selected based on the preliminary test results of 6 and 12 mm welding widths, and a superimposed type of seam was applied. Light scanning microscopic images were used to examine the effective weld locations and their morphology at the joining interface. The parametric influence of ultrasonic welding technique on-seam quality and their tendencies in the relationship were analyzed. Optimized peel strength yielding parametric levels were also assessed numerically. The result shows that the optimal peel strength value was obtained at a welding speed of 2.318 m/min, power of 119.382 W, and pressure force of 349.729 N for a 12 mm welding width. The weld seam thickness had an inverse relationship with the peel strength, and a higher amount of thickness was reduced to 12 mm welding width than 6 mm. Microscopic cross-sectional image of weld seam indicated that a compressed yarn between the coating material at higher welding power and pressure force in lower welding speed. A nonlinear quadratic numerical model was developed to predict the peel strength, and their results were close to the regressed diagonal line against the actual points. The statistical analysis was carried out to show the significant effect of process parameters on peel strength, whereby the obtained results were statistically significant.

Fabric image retrieval, a special case in Content Based Image Retrieval, has high potential application value in many fields. Compared with common image retrieval, fabric image retrieval has high requirements for results. To address the actual needs of the industry for Mélange fabric retrieval, we propose a novel framework for efficient and accurate fabric retrieval. We first introduce a quantified similarity definition, soft similarity, to measure the fine-grained pairwise similarity and design a CNN for fabric image representation. An objective function, which consists of three losses: soft similarity loss for preserving the similarity, cross-entropy loss for image representation, and quantization loss for controlling the quality of hash code, is used to drive the learning of the model. Experimental results demonstrate that the proposed method can not only achieve effective feature learning and hashing learning, but also effectively work on smaller datasets. Comparative experiments illustrate that the proposed method outperforms the compared methods.

The pursuit of sustainability has necessitated more renewable resources in construction materials. Plant-based natural fibres, which can be found globally, are abundant, low-cost and renewable. Moreover, plant-based fibres can improve the mechanical properties of construction materials as a low-cost, environmentally friendly renewable option. Accordingly, a thorough understanding of the characteristics and drawbacks of plant fibres, focussing on their use in cement-based composites, is needed to explore their potential in structural applications. Therefore, this study developed a conceptual framework to assess the factors affecting plant-based natural fibres and cement composites. The paper further demonstrates the application of the proposed framework to predict associated challenges and offers appropriate solutions. Finally, date palm fibres are suggested for future applications of the proposed conceptual framework. Graphical Abstract This is a visual representation of the abstract.
