What Do You Know About Fibers And Fabrics?

Viscose is not a natural fiber from a plant or animal source. It is a synthetic fiber made from cellulose, a natural polymer found in wood pulp. Through a process called viscose or rayon production, cellulose is chemically treated to create viscose fiber. Therefore, while cotton, wool, silk, and linen are all natural fibers obtained from plants or animals, viscose is a man-made fiber derived from cellulose.

Spinning is the process of converting fibers into yarn. It involves twisting and drawing out the fibers to create a continuous thread. This process is commonly used with natural fibers such as cotton, wool, and silk, but is also used with  synthetic fibers. Spinning is an essential step in the textile industry, as it prepares the fibers for further processing, such as weaving or knitting, to create fabrics and textiles.

Looms are specifically designed machines used for weaving. Weaving is the process of interlacing two sets of yarns, the warp, and the weft, to create a fabric. The warp yarns are held under tension, and the weft yarns are interlaced with them. Other options like a weft knitting machine, circular knitting machine, spinning wheel, and sewing machine are not used for weaving. Instead, these are used for other fabric production processes like knitting, spinning, and sewing.

Knitted fabrics are not made on a loom. Instead, they are made by interlocking yarns together using knitting needles or a knitting machine. Looms, on the other hand, are used to weave fabrics by interlacing warp and weft yarns. Knitted fabrics are known for their stretchiness, loop structure that traps air for insulation, tendency to curl at the edges, and the possibility of laddering and unraveling if a thread breaks.

Woven fabrics are known for their strength along the grain of the fabric, as mentioned in the fourth option. Additionally, woven fabrics can be made in different weaves such as plain, twill, or satin, as stated in the last option. They are also firm and do not stretch much, as mentioned in the second option. However, woven fabrics do not have loops with one interlocking yarn, which is mentioned in the third option. This characteristic is more commonly associated with knitted fabrics, not woven fabrics.

 Jersey is actually a type of knit fabric. Woven fabrics are created by interlacing two sets of yarn at right angles to each other, while knit fabrics are made by interlocking loops of yarn. Jersey fabric is known for its stretch and softness, making it a popular choice for clothing items like t-shirts and dresses.

T-shirts are typically made of knitted fabric, not woven fabric. Knitted fabric is made by interlocking loops of yarn, while woven fabric is made by interlacing two sets of yarn at right angles. T-shirts are usually made using a knitting technique, which gives them stretchiness and a more comfortable fit. Therefore, T-shirts would not usually be made of woven fabric.

Towels are not usually made of knitted fabric. While socks, cardigans, swimming costumes, and gloves are commonly made of knitted fabric, towels are typically made of woven fabric. Woven fabric allows for more absorbency and durability, which are important characteristics for towels. Knitted fabric is more commonly used for products that require stretch and flexibility, such as socks and gloves.

Non-woven fabrics are not made from yarn. Unlike woven or knitted fabrics, non-woven fabrics are made by bonding or felting fibers together rather than weaving or knitting yarns. This characteristic sets non-woven fabrics apart from other types of fabrics.

Polystyrene is not a manmade fiber because it is a type of plastic. Manmade fibers are typically created through chemical processes using synthetic materials. Polyester, nylon, acrylic, and acetate are all examples of manmade fibers commonly used in the textile industry. Polystyrene, on the other hand, is a thermoplastic polymer that is often used in packaging materials, insulation, and disposable food containers. It is not commonly used to make fabrics or fibers.

Fibers such as polyester and cotton are often blended together when spinning a yarn because it combines the good performance characteristics of the fibers and reduce the effect of the less desirable ones. Additionally, the cost of the fiber could be less than using just one fiber. This blending process helps to create a yarn that has improved properties and is more cost-effective.

Fleece jackets are typically made from synthetic materials such as polyester or nylon, which are woven fabrics. Non-woven fabrics are made from fibers that are bonded together rather than being woven or knitted. Disposable knickers, wadding, interfacing (vilene), and berets can all be made from non-woven fabrics, but fleece jackets cannot.
