Protective properties of warp-knitted spacer fabrics under impact in hemispherical form. Part II : effects of structural parameters and lamination
SAGE Publications, 2014Co-Authors: Yp Liu, Hu HAbstract:This part aims to investigate the effects of structural parameters and lamination on the impact force attenuation properties of warp-knitted spacer fabrics developed for impact protectors. A series of warp-knitted spacer fabrics was produced on a double-needle bar Raschel Machine by varying their structural parameters including spacer monofilament inclination and fineness, fabric thickness, and outer layer structure. The effects of fabric structural parameters, impact energy levels, and laminated layers on the protective performance of the spacer fabrics were tested and analyzed based on the assessment of the peak transmitted force. The results showed that all the structural parameters significantly affect the impact force attenuation properties of the warp-knitted spacer fabrics. It was also found that lamination of the spacer fabrics can effectively improve the force attenuation performance. Three layers of the developed warp-knitted spacer fabrics in a total thickness of about 2.5 cm can meet the requirement of the transmitted force lower than 35 kN at an impact energy of 50 J according to the European Standard BS EN 1621-1:1998.Institute of Textiles and Clothin

3D simulation model of warp-knitted patterned velvet fabric
International Journal of Clothing Science and Technology, 2016Co-Authors: Aijun Zhang, Ying Xiong, Gaoming JiangAbstract:Purpose Realistic geometric description is essential for simulating physical properties of warp-knitted velvet fabrics, which are widely used for home-textiles and garments. The purpose of this paper is to provide an approach to the description of patterned piles and propose a customized simulation model to realize highly real-time simulation of warp-knitted velvet fabrics in three dimensions. Design/methodology/approach Based on knitting technology and structure features, a mathematical model to qualify forming possibility of piles is conducted by assessing underlaps of pattern bars and pile ground bars. When the pile areas and ground areas are classified, a three-dimensional (3D) space coordinate is built, of which the z-axis is divided into equal spaces to form certain multi-layer textured slices. Color and transparency of piles on each textured slice can be computed and generated by mapping to 3D geometrical grid layers with particular mapping relationship. Moreover, piles’ deflection and spatial collision are also taken into account to make sure high uniformity with real fabrics. Findings According to the models built, a simulator special for warp-knitted patterned velvet fabrics is programed via Visual C++ and the models are proven practical and easily implemented by comparing simulated effect of one sample with real fabric. Research limitations/implications Because of present limited research, 3D simulation of patterned velvet fabrics knitted on double-needle bar Raschel Machine as well as 3D shadow effect will be studied in the further research. Practical implications The paper includes implications for designing patterned velvet products and shows convenience to instantly see finished effect without sampling on Machine. Originality/value This paper fulfills a featured simulation method for warp-knitted patterned velvet fabrics in 3D dimensions for the first time.

Structural deformation behavior of Jacquardtronic lace based on the mass-spring model
Textile Research Journal, 2016Co-Authors: Aijun Zhang, Honglian Cong, Gaoming JiangAbstract:To simulate the structural deformation behavior of Jacquardtronic lace, which is formed on a multibar Jacquard Raschel Machine and is widely used in female fashion, the key influencing factors on structural deformation were introduced and a tailored mass-spring model was built in which the lace was considered to be numbers of evenly distributed particles connected by elastane springs. These springs covered structural springs, restriction springs and spiral springs, respectively, created for ground pillars, Jacquard inlays, pattern lapping and elastane yarns. The elastane force on particles was analyzed to study motion state and deformation behavior with the explicit Euler method. The deformation simulated models were implemented by a simulator program via Visual C++ and were tested with a lace sample. Particular attention was paid to analyzing the effect of Jacquard structures and yarn tension on deformation and the detection model was introduced to avoid improper deformation caused by excessive yarn tens...

Knitting property research of PP monofilament on Raschel Machine
2004Co-Authors: Jiang Gao-mingAbstract:PP monofilament has very special physical and chemical properties; but its Young's modulus and bending strength are high, and elongation is low, so its knitting property is no good. As a result, it is difficult to knit PP monofilament on knitting Machine, esp. the coarse monofilament. The mechanical properties, including tension, compression, bent and friction are researched in the article, and means how to improve the knitting property of PP monofilament are presented based on the knitting trail on Raschel Machine as well.
