What is Fabric: Definition and 116 Discussions

A textile is a flexible material made by creating an interlocking network of yarns or threads, which are produced by spinning raw fibres (from either natural or synthetic sources) into long and twisted lengths. Textiles are then formed by weaving, knitting, crocheting, knotting, tatting, felting, bonding, or braiding these yarns together.
The related words "fabric" and "cloth" and "material" are often used in textile assembly trades (such as tailoring and dressmaking) as synonyms for textile. However, there are subtle differences in these terms in specialized usage. A textile is any material made of the interlacing fibres, including carpeting and geotextiles, which may not necessarily be used in the production of further goods, such as clothing and upholstery. A fabric is a material made through weaving, knitting, spreading, felting, stitching, crocheting or bonding that may be used in the production of further products, such as clothing and upholstery, thus requiring a further step of the production. Cloth may also be used synonymously with fabric, but often specifically refers to a piece of fabric that has been processed or cut.

    Stretched fabric cylinder between two hoops - what is the shape?

    Hi Everyone, Imagine a tube of fabric stretched between two hoops, like the one's seen here.. http://www.stretchshapes.net/blog/wp-content/uploads/2012/08/A1.png That is, a cylinder made of an elastic material, under tension. Is there a name for this shape? Is there a generic equation...

    Is there a washable magnetic fabric in existence?

    Hi, I'm not a materials scientist by any means, but I have a business idea that would involve the use of a washable magnetic fabric. Does anyone know of any such material? If not, does anyone know a good place I might look to find such information? I've tried googling, but I haven't found...

    What is the 'fabric of the cosmos' and what drives its cosmic loom?

    My cosmology friend and I were watching an episode of NOVA called "The Fabric of the Cosmos" hosted by Brian Greene. I asked if he could further explain the reference to the "fabric of the cosmos". He said, "Space-time has a geometry much like a piece of fabric. Picture our universe being...

    How do we know there is a timespace fabric?

    When 2 magentic objects interact with each other, it is because they interact with each others magnetic field, not because their presence alters an existing magnetic field. The way I understood spacetime, the theory goes that a spacetime fabric stretches throughout the known universe and mass...

    Question about Mulder and Scully experiment in The Fabric of the Cosmos

    In the fabric of the Cosmos by Brian Greene there is an experiment using the example of Mulder and Scully and boxes. It is an analogy to Bell's experiment determining whether articles have definite spin before you measure them. It shows that if they have definite spin before you measure them two...

    Question about the fabric of space

Don't panic, i haven't JUST learned this, it just has provoked a thought.Is space expanding because of the momentum brought by the big bang, like...

    Question about the space-time fabric

    Ok, I sort of understand the space-time fabric but there's one thing that bugs me. In this picture, how does the satellite orbit the earth? I know it's because of gravity but how is affected by the curvature of the space-time? It's not touching the curved part. Or does the curvature go all...

    What is the nature of the gravitational field and its relationship to matter?

    In GR, there is said to exist a fabric of space-time, and gravity is the warping of the fabric of space-time. Since GR is simply an extension of SR, the fabric of space-time should exist for both, then, both relating to the same universe and all, right? So could the fabric of space-time be...

    Connection between fabric of space, max. speed (of light) and time dilation

    Gravitational force vs space time fabric

    What is the Fabric of Spacetime Made Of?

    General Relativity has always fascinated me and I understand how the fudamentals of the so called fabric of Spacetime work, but never do I hear from anybody what the fabric of Spacetime is made out of. Is it some other type of natural force and if so is it related to the 4 fundamental forces.
