Viscose yarn actually behaves quite a bit like cotton, as it's very absorbent and breathable. This along with its lightweight characteristic and hardiness makes it a great fabric for warm weather wear. Since it's so cheap to produce, it's cheap to the consumer, as well, but it won't be very helpful for people who are concerned with staying warm, because it does not insulate well. People who live in warmer areas will find viscose is their best friend, but people who live where there are harsh winters and mellow summers, or people who are more concerned with the environment, may use this fiber less.

Cotton yarn is a natural, plant-based fiber. It is soft, versatile, and breathable. Cotton fabric is one of the oldest known materials and is still a staple in the knitting industry. Cotton yarn is a great alternative for anyone allergic to wool, or who want a lighter feel to their project. Cotton dyes beautifully and hence the yarns are available in bright and rich hues. It is breathable and hence is preferred during summers. It is a great absorbent. Cotton yarn is best for making household items such as pillows, rugs, towels, washcloths, market bags, dishcloths, and a lot more.

Acrylic yarn is a fiber that is man-made. It is developed from polymers that are synthesized from petroleum products. There are many benefits to using acrylic yarn. Looking into its properties and applications will help you decide whether you should go ahead with this yarn for your knitting project or not. Acrylic yarns were first developed by DuPont during the 1940s. Within a decade, these yarns became a rage and were being produced on a massive scale. These polymers are created from several processes that produce string-like strands that resemble wool hair. These are then spun into a yarn.

Nylon yarn is a synthetic material yarn that can be made to resemble the look and feel of many natural fibers. Originally, nylon was created as a substitute for silk when the latter material became difficult to obtain. Nylon is strong, slightly stretchy, and generally cheaper than natural fiber yarns. This makes nylon good for many types of knitting projects. It is also usually easy to work with, so it may be a good material choice for beginner knitters.

Wool yarn is a wonderful choice for winter clothing accessories. It offers a warm feel, even in the rain and will last you for years without losing shape. It can also be cleaned rather easily when it gets stained and this is why so many knitters around the world prefer this natural yarn fiber over others. On the downside, wool can be slightly itchy, especially for individuals who are allergic to some types of wool.

Fancy yarn is made with a distinctive irregular profile which is different from basic single and folded yarns. This profile enhances the visual and textural properties of the fabric. Fancy yarns are also termed novelty yarns, specialty yarns, effect yarns and fashion-oriented yarns, and can incorporate deliberate "defects" or variations distributed randomly or in a pre-defined order, along with colour to give visually and texturally attractive difference to the fabric. Colour effects along the yarn length are introduced by twisting different coloured yarns, spinning blended dyed fibres, or by irregularly printing/dyeing spun yarns.

Functional yarn (also known as high-performance yarns) has numerous characteristics that set it apart from conventional yarns. The functional yarn has the protective property of water absorption and resists moisture, thereby protecting your skin. Some functional yarns are fireproof and help fire extinguishers in cutting down the fire.

Filament comes on spools, makes it easy to feed into your 3D printer. Filaments are plastic materials in spaghetti-like strands that are melted and extruded onto your printer's print bed to make your 3D model according to the specs you chose in your 3D software.
