Textile weaving technology

The main commercial developments in the jute industry have been concerned with the spinning and weaving technology, and considerable improvements in productivity have also taken place. However, it is time now to consider what new innovations would assist the spread of jute materials into textile uses outside the traditional fields of packaging and carpets. 

Medical masks are mostly produced from textiles. Weaving, knitting and nonwoven technologies are used to produce masks. But, nowadays, nonwoven technology is preferred for the mask production method. Nonwoven surfaces has good filtration properties. Mostly polyester and polypropylene fibers are used for mask production. 

Another approach to create a compliant and elastomeric prosthesis is to design a multilayered structure. After all, the structure of a natural artery is multilayered, with each layer of the media and adventitia serving a different, clearly identifiable mechanical role. By harnessing the latest three dimensional textile knitting and weaving technologies, our laboratory is investigating the scope and limitations of this approach. ...

George de Mestral was a keen Swiss mountaineer who was driven by curiosity to work out why it was so difficult to remove the prickly burrs from his clothes and dog s fur after walks in the mountains. A simple observation tmder the microscope revealed that each burr was covered in hundreds of needle-like structures with a curved tip at the loose end, resembling a hook. This inspired Mestral to engage weaving techniques to interpret his observations into a fibrous textile system, able to deliver dry adhesion. The outcome was patented and commercialized tmder the trademark Velcro , a technology used widely in many sectors from apparel to space. 

Narrow weaving and braiding technologies (Fig. 2.5) are applied for the production of belts and ropes across a wide range of dimensions. Narrow woven belts, sewn-on textiles and foils can considerably enhance the maximum span length. Ropes are used to create tensile connections between textiles/foils and the larger elements of a primary construction. 

Dqiending on the final application of a textile scaffold, warp knittii weaving, braiding and non-woven technologies can be used to manufacture the textile structure. Thermal treatment can be iqqilied to adjust the pmoshy, geometry and elasticity of the produced textiles.
