Spacer Fabrics from Hybrid Yarn with Fabric Structures as Spacer

چکیده
Within the scope of Collaborative Research Centre SFB 639 "Textile-reinforced composite components for function-integrating multi-material design in complex lightweight applications", woven and flat-knitted spacer fabrics from commingled hybrid yarns are developed, pressed and the characteristics of the formed composite structures are tested. The developed spacer fabric structures have Ushaped and Vshaped connections with woven or knitted crosslinks which yield good performance under complex stresses especially under bending strength in comparison with conventional spacer fabrics. Various modifications on flat knitting and weaving machines are executed to enable hybrid yarn processing into 3D textile preform structures. These new developments extend the performance and the application areas of costeffective textile reinforced thermoplastic composites. Integration of functional components and further near-net-shape structures are the main emphasis of future work.

Warp-Knitted Fabrics Simulation Using Cardinal Spline and Recursive Rotation Frame
To realize 3-D simulation of warp-knitted fabrics, this paper proposes a 3-D loop modeling method based on Cardinal spline and recursive rotation frame method. Fabric structure and loop geometry are studied to form a visible lapping detection model and loop geometrical key points obtained according to chain links and yarn arrangements. In this paper, eight points are set for stitched loop and t...
متن کاملAn Experimental Study of Compression Behavior of Warp-knitted Spacer Fabric
This paper presents an experimental study of the compression behavior of a typical warp-knitted spacer fabric which is specially developed as a cushioning material for human body protection. The fabric has a highly heterogeneous and discontinuous structure and exhibits a complicated compression behavior. Different test boundary conditions and sample sizes were first adopted to conduct compressi...
متن کاملAn Analytical Study of Initial Shear Behavior of Plain Woven Hybrid Fabrics
During recent years, the fabrics made from different yarns have been used for industrial purposes such as composite materials. Given the importance of the shear properties of these fabrics, a mechanical model based on the Grosberg and Park's Model for hybrid plain-woven fabrics is proposed. In this model, using the Energy method, the initial load-shear angle behavior of hybrid fabrics is calcul...

In this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. Fabrics are impregnated with Shear Thickening Fluid (STF). The effects of the (STF) have been considered as frictional effect. The STF has been made (Nano Silica and Polyethylene Glycol (PEG)) and then diluted by ethanol proportion of 3:1. Yarn pulling out test from in...
متن کاملIn-Vitro Analysis of the Effect of Constructional Parameters and Dye Class on the UV Protection Property of Cotton Knitted Fabrics
Cotton knitted fabrics were manufactured with different yarn types (conventional ring spun yarn and torque-free ring spun yarn) with different fibre types (combed cotton and combed Supima cotton) and yarn fineness (Ne30 and Ne40). These fabrics were then dyed with three types of dye (reactive, direct and sulphur dye) with three dye concentrations (0.1%, 1.0% and 5.0% on-weight of fabric (owf)) ...
