Favorite Fibers

Natural & Synthetics/Man Made Fibers




(NativaStore, 2011)

Why Natural Wool?

For me carpets are best when it’s made of natural fabric especially when it’s wool, because wool has many benefits. According to Michael, 2005 of LotusOrganic.com, here are some reasons why wool is my favourite and why it’s highly recommended to use:

·    Built-in climate control. Wool is a natural insulator to keep you warm in winter and naturally breathable to keep you cool in summer. Wool fiber helps to keep your body at the optimal temperature zone for comfort and rest. When used in blankets, synthetic fibers, down and even cotton fibers do not breathe as well as wool, and are more likely to trap heat in your bed. Wool buffers the extreme cold or hot air on the outside, keeping your body in that comfort zone.
·    Naturally absorbent fiber. Wool fiber is the original wicking fiber. Its coil-like shape pulls excess heat and moisture from your skin while you sleep. Wool fabrics can absorb up to 30% of their weight without feeling heavy or damp. Cotton fabrics begin to feel damp after 15%. The absorbent fibers "breathe" by wicking away moisture from the body and releasing it into the air. This quality makes wool fabrics comfortable to wear in warm and cold weather.
·    Natural mildew and mold resistance. Wool's natural resistance to mildews and molds comes from the way it repels moisture, and lets moisture pass through it's fibers without holding the moisture. Mildews and molds require moisture to live and grow.
·    Perfect insulator.  Wool is warm in winter and cool in the summer because of its hydrophilic ability to wick away excess moisture. In the winter, wool removes moisture from the skin to keep the wearer feeling warm and dry and wool’s insulating qualities trap dry air and warmth near the skin. This is unlike synthetic fleece, which is warm but does not breathe easily. Wool's natural insulating quality and its ability to shed water results in a fabric that keeps the body warm even when it's raining. In the summer, wool’s coil-like shape pulls excess heat and moisture from your skin helping the wearer stay cooler.
·    Water repellent. Tiny overlapping scales encase the wool fiber like tiles on a roof. This allows wool to repel rain, snow and liquid spills with ease.
·    Wool is durable. Laboratory tests have shown that wool fibers resist tearing and can bend back on themselves more than 20,000 times without breaking. Cotton breaks after 3,200 bends, silk fibers break after 1,800 bends, and rayon fibers break after just 75 bends. Wool clothing will last for years. Wool resists spills, dries very quickly and is mildew resistant.
·    Naturally wrinkle resistant. Wool fabrics resist wrinkles. Wool is the most resilient fiber because it has a natural crimp that helps it keep its shape. Wool fibers can be stretched and still bounce back to their original shape.
·    Fire retardant. Wool is safer to wear having natural fire-retardant properties. It can resist flame without the chemical treatment involved in fireproofing. Synthetic fleece is oil based, ignites easily, burns fiercely and melts. If your synthetic fleece is fire proofed, then you have the fire proofing chemicals next to your skin.
·    Resists static, dirt and dust. Wool fabric doesn't collect much static because of its absorbent fibers. Static attracts lint, dirt, and dust. Wool fabrics also clean easily because dirt sits on the surface of the fiber. The outside surface of the wool fiber consists of a series of overlapping scales, similar to the feathers on a bird, making it easy to brush off and for stains to lift out.
·    Wool is colorful. There are an amazing variety and number of breeds of sheep that come in a wide array of colors giving us a huge number of natural colors. In additional to natural color-grown fibers, the structure of wool fibers allow wool to easily accept dyes without the need for harsh and sometimes toxic chemicals to prepare the fiber for dyes. When wool fabrics are dyed, the dye reaches to the core of the fiber and bonds permanently. Almost any color and dye can be used.
·    Naturally non-allergenic. Wool is almost entirely non-allergenic. Although some people do have a rare natural allergy to Lanolin, the oil found in wool, most people's allergy to wool is a reaction to the many harsh and toxic chemicals that go into the treatment, and finishing of conventional wool garments and bedding. Serious chemical abrasives are routinely used to wash raw wool for processing. Chlorine and mothproofing chemicals are routinely applied to conventional wool before turning it into a finished product.
·    Renewable and Sustainable. Wool is a renewable resource that can be shorn from sheep annually. It is biodegradable and kinder to the environment than oil-based synthetics, which contribute to global pollution. Wool is sustainable. Wool from free-grazing sheep, treated ethically throughout their long lives, represents a traditional small-scale industry that once thrived in America. Today, many small organic farmers are returning to this sustainable industry to create clean and healthy wool that is produced without stress to the animals or the environment. 

 Amongst these natural fabrics I then choose Argentinean wool. Argentina is very well known of their wool because of their abundant sheep production. Hand woven carpets are very interesting in how they have to use different techniques to form geometric patterns to beauties. It’s noted for its gloss and sheen with natural resistance to soiling.

GABBEH RUGS


Gabbeh rugs are fabulous. The wonderful colors, the rich silky wool and the minimal designs have inspired countless rug lovers.
A Gabbeh rug is an indigenous rug that's made in mountains area of Iran by tribal weavers. These rugs have an ancient history, and thus have developed a subtle sophistication over many hundreds of years. Each piece begs the attention of those looking at it. Their bright primary colors, designs, and unique patterns .The beauty of Gabbeh rugs was discovered in the nineteenth century, as people from outside began to notice the wonderful handmade rugs of the Qashqai tribe.These rugs bore a variety of patterns and came in many designs. The main weavers of the Gabbeh rugs were the Qashqai tribes living in the Zagros Mountains. These mountains, the highest in Iran, help provide the local peoples with a unique culture of which the Gabbeh rugs cannot be separated. 

"Gabbeh" comes from a Persian word that means "rough" or "uneven," and this is exactly how the original Gabbeh rugs were. Handmade, the rugs were weaved together in rough patterns that different substantially from those in nearby areas. This instantly made the rugs something of an article upon discovery. It wasn't until many years later, however, that people realized the rugs could be marketed for a more broad use. most Gabbeh rugs display only geometric shapes (usually rectangles) and simple animals, the relative lack of color variety is not a disadvantage for this rug. In fact, it helps identify the rug and secure its position as culturally unique. This rug will give you just enough touch of the exotic, they will provide you with beautiful designs from different cultures. The Persian Gabbeh rug is perfect for those looking to provide a tribal feel to their homes and it's a great way to show a different culture to others and also you can never go wrong with antique style rugs or vintage style rugs.

NATURAL COTTON RUG


Cotton rugs are  strong and stable, natural product, soft fiber, generally inexpensive. Generally more affordable than wool or silk; easy to clean. The problem with the cotton rug is that it doesn't wear well over the period of time. But natural cotton rug comes in different colors and different designs although Cotton rugs are generally found in a flat weave and are a popular selection for kitchens because most smaller sizes can be easily washed. Cotton pile can sometimes become felted and tends to attracts dirt easily.It's best for kitchens, children’s rooms, casual spaces.

Natural And Synthetic Fibers

Natural fibers are flat-woven rugs meaning, they have no pile and are often reversible. They’re crafted from plant-based fibers which are tightly woven to create a mat or rug. Sometimes, cotton is added for softness, but primarily they consist of the fibers from jute, bamboo, sisal, seagrass, and coir, the strands from coconuts. Traditionally used in homes’ entryways for their tough, stain-resistant materials, they work in nearly every room, depending on which you choose, and many can hold a variety of dyes for extra color.

Natural fibers include:

-Wool
-Sisal
-Maize
-Coir
-Cotton
-Jute

a. Wool - used for centuries  in the manufacturing of carpet, wool is still the standard against which other carpet fibers are judged. It is generally the most expensive carpet fiber and is commonly used in woven carpets. There are also 5 characteristics of wool from different countries; New Zealand Wool, Argentinean Wool, Indian Wool, Iraqi Wool and Scottish Wool



b. Sisal (Scratch rush) - natural product that grows like grass, it is light cream or oatmeal in color. Sisal is a strong, woody fiber produced from the leaves of the agave plant which is found in Central America, the West Indies, and Africa.



c. Maize - made from corn husks.



d. Coir (Coconut Plush)  a strong flexible hair like fiber from coconut shells. its pale yellow fibers are spun into a yarn which finally woven into either flat weave carpeting or cut pile rugs and mats.



e. Cotton - softer than wool but less durable.



f. Jute -  the softest of all natural fibers. It may fade or darken the color when exposed to sunlight, and its fiber disintegrates with prolonged exposure to moisture.


Synthetic fibers are textiles that are made from chemicals. These fibers are stronger than natural fibers.


Synthetic fibers include: 

-Polyester
-Acrylic
-Spandex




a. Nylon - it is made from polyamide fiber, derived from a diamine and a dicarboxylic acid that is formed into thin strands and woven into fabric. It is a synthetic fabric that utilizes the chemical by-products of coal, petroleum and agricultural products. Synthetic polymers give nylon fabrics a low absorbency rate ideal for swimwear, stockings and athletic clothing.





b. Polyester - is a term often defined as “long-chain polymers chemically composed of at least 85% by weight of an ester and a dihydric alcohol and a terephthalic acid”. In other words, it means the linking of several esters within the fibers. Reaction of alcohol with carboxylic acid results in the formation of esters.

Polyester also refers to the various polymers in which the backbones are formed by the “esterification condensation of polyfunctional alcohols and acids”.

Polyester can also be classified as saturated and unsaturated polyesters.

Saturated polyesters refer to that family of polyesters in which the polyester backbones are saturated. They are thus not as reactive as unsaturated polyesters. They consist of low molecular weight liquids used as plasticizers and as reactants in forming urethane polymers, and linear, high molecular weight thermoplastics such as polyethylene terephthalate (Dacron and Mylar). Usual reactants for the saturated polyesters are a glycol and an acid or anhydride.

Unsaturated polyesters refer to that family of polyesters in which the backbone consists of alkyl thermosetting resins characterized by vinyl unsaturation. They are mostly used in reinforced plastics. These are the most widely used and economical family of resins.






c. Modacrylic - is a manufactured fiber in which the fiber forming substance is any long chain synthetic polymer composed of less than 85% but at least 35% by weight of acrylonitrile units. (-CH2CH[CN]-)x.

A modacrylic is a synthetic copolymer. Modacrylic fiber is inherently flame resistant. Although it burns when directly exposed to flame, it doesn't melt or drip and is self-extinguishing when the flame is removed. Modacrylic is widely used in high performance protective clothing, such as firefighting turnout gear, because flame resistance is combined with other desirable textile properties such as durability and good hand feel.

Modacrylics are soft, strong, resilient, and dimensionally stable. They can be easily dyed, show good press and shape retention, and are quick to dry. They have outstanding resistance to chemicals and solvents, are not attacked by moths or mildew, and are nonallergenic. Among their uses are in apparel linings, furlike outerwear, paint-roller covers, scatter rugs, carpets, and work clothing and as hair in wigs.


d. Polypropylene - is the first stereoregular polymer to have achieved industrial importance. The fibres from Polypropylene were introduced to the textile arena in the 1970s and have become an important member of the rapidly growing family of synthetic fibres. Today Polypropylene enjoys fourth spot behind the “big three” fibre classes, i.e. polyester, nylon and acrylic. However, as opposed to other commodity fibres, its use as apparel and household textiles has been rather limited; the bulk of the fibre produced is used for industrial applications.





f.  Acetates -
Brand name like Avisco, Celaire , Cromspun , Estron. Is the man-made fiber that is made of cellulose acetate, which is the acetic acid ester of cellulose





g. Azlons- Brand name like Vicara. is a synthetic textile fiber composed of protein material derived from natural sources. For example, soy, peanut, milk or corn. Currently it is used in clothing.

h. Rayons- a textile fiber or fabric made from regenerated cellulose (viscose).

i.  Sarans- trade name for a number of polymers made from vinylidene chloride (especially polyvinylidene chloride or PVDC), along with other monomers. Brand names like Rovana , Saran.

j. Trancetate - is derived from cellulose by combining cellulose with acetate from acetic acid and acetate anhydride. The cellulose acetate is dissolved in a mixture of methylene chloride and methanol for spinning. Brand names like Arnel.




All of these fibers are wrinkle-resistant, they tend to pill easily and do not absorb well. There are advantages and disadvantages to synthetic fibers.  In general, the advantages of synthetic fibers are that they are durable, moth-resistant, easy to care for, cheap and abundant. Disadvantages are that they are made with petroleum, a non-renewable resource, melt easily in high temperatures and cause some people to experience allergic reactions.


BLENDS

Blending is the combining of different fibres together intimately to achieve a desired product characteristic. Blends can influence colouring, strength, softness, absorbency, ease of washing, resistance to wrinkling, ease of spinning, cost, etc.

Advantages of Blending: 
  • When two different types of fibres are blended, the properties of these two different fibres are synergised. For instance, in the blend of cotton and polyester, cotton provides the absorbency and polyester provides the strength.
  • Blending is done to produce a fabric, which is economical by combining the aesthetic comfort properties of the natural fibres with the easy care and strength properties of synthetic fibers.

  • Blending also helps to provide the fabric’s light weight with all desirable characteristics.Improving spinning, weaving and finishing efficiency and the uniformity of product.
Methods of Blending:
Blending can be done at the opening stage, drawing etc.
  1. In the initial opening stage of the blow room operation, the fibres are spread one on top of the other and fed into the blending feeder.
  2. The blending can also be done in the carding stage.
  3. Similarly the blending can be done at drawing or roving stage.
  4. A filament yarn blended contains yarns of different deniers (denier is the yarn numbering system used for filament yarns) blended together.
