Fabric Definition and 119 Threads

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.

    I Is Spacetime a Real Physical Entity or Merely a Conceptual Framework in Physics?

    Given that physics is the study of the physical world, what exactly is spacetime if it is an actual "real world thing", a curved medium or "fabric" guiding the movements of masses, and what is the physics of how this guidance works. As far as I know, space is a vacuum (where not occupied of...

    B Can We Use Space/Time Fabric to See the Past?

    Common these days is explaining worm holes and the space and time correlation as a fabric which could allow for the fabric to be manipulated in a way that would allow for time travel. The way I’ve understood the concept is that you could fold the fabric to touch two different areas together...

    Tension in a deformed cylindrical bag on a surface

    A cylindrical bag is made from a freely deformable fabric, impermeable for air, which has surface mass density σ; its perimeter L is much less than its length ##l##. If this bag is filled with air, it resembles a sausage. The bag is laid on a horizontal smooth floor (coefficient of friction µ =...

    How Do Cashews Cause Fabric Discoloration?

    Hi everyone I was soaking a red T-shirt in water and accidentally dropped a cashew nut into the bucket. I think the nut would have been soaking with the T-shirt for maybe three or four days. When I emptied out the water, I noticed the spot on the T-shirt where the cashew had rested became...

    Do Ants Eat Fabric or Polyethylene Foam in Exercise Mats?

    I have an exercise floor mat which I just bought new 2 weeks ago but there was already holes at bottom not caused by me or factory defect. What kinds of ants can eat fabric? And what fabric could they really bite through? Or are they attracted to the polyethylene foam inside? Does this taste sweet?

    Determine horizontal separation of fabric from diffraction pattern

    B Matter & Space-Time: A Discussion

    I was having a discussion with someone, regarding whether Time Travel was possible. The opposing individual argued that people are composed of matter that is simply woven into the fabric of space-time, therefore, rendering us unable to travel through time. I wasn't sure if he was right because I...

    Can I mix carbon fiber fabric with most glues?

    B Could singularities be just rips in the space-time fabric?

    First off, this is just an assumption. My knowledge of the field is extremely limited and I beg you to come and correct my mistakes, so I can learn. So, I guess we all know how that space-time fabric is bended by gravity. When a star dies, all of the atoms are brought extremely close...

    I've always wondered how we came to come up with such an idea. Was he one day sitting around and thinking, then made a random assumption and go "ah hah!". Or did his idea come up through his calculations on the nature of how gravity should cause interaction? Is their a literal fabric of space...

    How Do We Quantify Stress on Fabric at Support Contact Points?

Because the material is fabric (non rigid) the compressive force from the higher pressure...

    Is Salt Water Really Effective in Neutralizing Rust on Fabric?

    B Resistance of Space-Time fabric

    According to relativity gravity is just an illusion caused by wrapping of space-time fabric by mass, right? So, what is the elasticity of of space-time? There must be some king of resistance for the wrapping, otherwise even a tiny mass would plunge in the space time for eternity.

    Is the metric basis for space expanding as the universe expands?

    I have read that as the universe expands that the "fabric" of spacetime expands. Does this mean that the metric basis for a given space is expanding? Also, does this mean the distances between the atoms in the lattice of matter is also increasing proportional to the expansion of the cosmos?

    Why is the fabric of space and time always portrayed flat?

    The concept of the fabric of time and space is confusing to me. I understand that an object with large mass can warp it, but that only makes sense to me if the fabric had only two spatial dimensions (assuming no warps). The space-time fabric is always explained visually as a flat plane, but...
