Improvement of Weld Quality Using a Weaving Beam in Laser Welding

This paper describes a way to improve the weld quality through suppressing the porosity formation and restraining the growth of columnar grains by using a weaving beam in laser welding. The experimental results show that the N2 porosity of beam-weaving laser welding low carbon steel can be remarkably reduced with increasing weaving frequency, and porosity can be eliminated when the weaving amplitude is only 0.5 mm; and the Ar porosity in the weld metal is decreased with increasing weaving frequency and amplitude when the welding speed is higher than 0.5 m/min. The beam-weaving laser welding of ultra-fine grained steel has been investigated. The experimental results show that beam-weaving laser welding with appropriate amplitude and frequency can partly restrain the growth of the columnar grain and improve the tensile strength of the weld metal.

Parametric Design Used in the Creation of 3D Models with Weaving Characteristics

The art of weaving is an ancient and beautiful technique that never fades. Various weaving techniques and various totem patterns contain rich cultural connotations. The development of cultural and creative industries often uses existing environmental materials to deconstruct and use them in innovative ways to reinspire and present another style. With the rapid progress of computer-aided design technology, digital applications in the design practice has become an important element, and parametric design is the best popular design method in recent years. This paper is mainly in view of the weaving crafts in the traditional culture of the world occupies an important role, and the precious traditional weaving crafts gradually lost. Therefore, it is planned to construct a 3D model with knitting characteristics through a parametric design method, and print out the prototype through the 3D printing mechanism, that is, the traditional craftsmanship is integrated into the modern manufacturing process with innovative techniques, to show the new style of this weaving craft culture that is different from the past, so that it not only retain its inherent spirit, but also can promote this ideal of cultural creativity.

AN ANALYSIS OF DYNAMIC PERFORMANCE OF BACK REST OF WEAVING MACHINERG

Periodic variations of warp tension during a weaving cycle results in corresponding variationsof back rest position.However,the oscillation of back rest,in turn,shows effect on the variation ofdynamic warp tension.As a force transfer medium,warp yarn,with specific dynamic performances,is certainly one of the factors influencing the movement of back rest.In this paper,warp yarn istreated as a viscoelastic medium in studying the dynamic behaviours of back rest.A mathematicalmodel of a back rest system is developed based on the automatic control theory.Several factors arelisted,which show influences on the performances of the back rest system.Analytical work is car-ried out to identify the effects on the frequency response of the back rest systen resulting from vari-ations of such parameters as the modulus of elasticity,of both fast-elastic and slow-elasticdeformations,and viscosity coefficient.

A STUDY ON THE RAW MATERIAL, STRUCTURE AND WEAVING INSTRUMENTS OF FABRICS BEFORE THE WEST ZHOU DYNASTY

In this paper, based on literature of relics of typical fabrics before the West Zhou unearthed in China till now, the weaving technology, including the raw material, the fabic structure, and the weaving instruments of that period was synthetically studied. The wooden loom parts unearthed in the Hemudu ruin, Zhejiang Prov. were studied with reference to the inscriptions on bones and tortoise shells as well as the characters casted on bronze objects, denoting the weaving instruments of pre-Zhou pcriod. The results show that, all the main natural fibres were utilized, all simple and combined weaves except the satin weave had appeared, and the weaving instruments might include the ground loom with 3 or 4 points support, besides the breast loom already reported.

Unraveling the Pattern Weaving Technology in Ming Dynasty

The Ming dynasty （1368 - 1644） inherited the lens-standing culture in China, of course including the textile technology. Besides a large amount of sinsle color damask silk, many pattern woven silk including dragon robes, patterned costumes and luxurious silk textiles are found in complicated and colorful pattern woven brocade called zhuang hua. It was prevailed in Ming dynasty when compared with the frequency of the name chuang hua recorded in related historical documents. These pattern silk and brcrade were produced by the advanced pattern weavin8 technology, which was well developed in Ming dynasty. From historical documents of＂Tian gong kai wu＂, Exploitation of the works of nature, there is the detailed description of the draw loom （hua Io ji） which can weave normal patterned textiles. It also indicated that to produce dragon robes needed much more high technique, similar to the hua Io ）i but more complicated and difficult. A big draw loom is found to weave Nanjing Yen brocade today inherits the technolosy to weave zhuang hua brocade. After sorting the historical documents, it is found that some records are coincident with the existed materials, both the silk textiles and weaving technology. With these evidences research and exploration, this dissertatien tries to unravel the pattern weaving technolosy in the Ming dynasty.

Increasing the Energy Efficiency of Air Jet Weaving Based on a Novel Method to Exploit Energy Savings Potentials in Production Processes of the Textile Industry

This article deals with the energy efficiency of textile weaving machines. A method based on exergy balances has been developed at the Institute for Textile Technology RWTH Aachen University （ITA）, Aachen, Germany in order to improve energy efficiency textile machines. The relay nozzles of the air-jet weaving technology need up to 80% of the energy of the weaving machine. At ITA, a new nozzle concept was developed. The developed geometry is a so called High-Volume-Low-Pressure nozzle （HVLP nozzle）, based on convergent nozzle aerodynamic theory. With this concept, energy savings up to 30% are possible.

A Brief Analysis of the Migration of Silk Weaving Craftsmen and the Spread of Silk Weaving Techniques in the Ancient Bashu Area along the Southern Silk Road

During ancient times,silk weaving techniques already matured in the Bashu area and“Shu Satin”silk products were widely known.Shu Satin not only performed as a high-quality commodity in the Northern Silk Road trade activities,but also conveyed cultural and social significance.Credit for the importance of Shu Satin must go to the extraordinary weavers in the Bashu area.The migration and circulation of these weavers spread the exquisite brocade and sericulture techniques throughout and beyond the Bashu area,and accelerated brocade and sericulture techniques in ancient southern China,Myanmar,and Vietnam.Accordingly,the Southern Silk Road can be seen as a path to disseminate the silk weaving techniques that originated in the Bashu area.This paper takes the migration of Shu Satin as its mainline and discusses how the weaving craftsmen spread the brocade and sericulture techniques throughout southern China during their travels and migrations,and the immeasurable contributions these craftsmen made to economic and trade activities along the ancient Southern Silk Road.This paper explores the technical accumulation and dissemination of brocade craftsmen in the Bashu area from three perspectives.The first perspective is the accumulation period of the ancient silk weaving techniques-the inflow of craftsmen from central China and the development and integration of the sericulture and silk weaving techniques in the Bashu area.The second is the technique dissemination period,centered on the silk weaving craftsmen in the Chengdu region of the Bashu area.The third is the techniques’outmigration period and the migration and circulation of craftsmen throughout the Bashu area.This paper strives to outline the dynamic lines that the Bashu silk weaving craftsmen created and the spread of their exquisite weaving techniques during their migration and circulation.This will illustrate that the ancient Southern Silk Road was not only a trade and cultural exchange zone for ancient silk commodities,but more importantly,it was a dynamic space for the dissemination and development of brocade weaving techniques.
