The Surprising Answer"},"content":{"rendered":"\n

Introduction-<\/h2>\n\n\n\n

The warm blanket in which you cover yourself during a cold night, or the fabric of the lightweight jacket that you take with you when going hiking; both are probably produced using fleece. Fleece is sometimes confused with wool, being thought of as directly coming off sheep as well. The term naturally misleads others into visualizing animal natural fiber. However, there is a catching news: fleece is not what has generally been believed.<\/p>\n\n\n\n

Fleece is a very common cloth towards the trends of clothing as well as domestic textiles. It is soft, warm, durable, and thus, is popular as an outdoor fabric and blanket, as well as sportswear. But you may be shocked by the origins. We will reveal the actual answer to what is fleece made of, discuss the manufacturing process, compare the material with the natural fabrics, and investigate its environmental impact in this article. At the end of it, you will have everything you need to know about this interesting fabric.<\/p>\n\n\n\n

What Is Fleece Actually Made From?<\/h2>\n\n\n\n
\"Plastic<\/figure>\n\n\n\n

The shocking truth is that, Modern fleece is polyester, a man-made polymer created with a petroleum product (crude oil). Rather than shaving off sheep or goats, fleece is constructed out of fibers made of plastic.<\/p>\n\n\n\n

Fleece was not made out of animal wool, as it is an entirely synthetical material with polyester as its main component.<\/p>\n\n\n\n

It is here that many people become surprised. Wool is a natural product while fleece is produced in factories and laboratories. Better yet, fleece is also recyclable, which means that fleece that has already been discarded can end up becoming the apparel you wear at home, to make it useful once again.<\/p>\n\n\n\n

Its softness and breathability, coupled with ease of care have made fleece a popular staple fabric of contemporary fashion. To fully enjoy it we need to understand how it is made.<\/p>\n\n\n\n

From Plastic Bottles to Cozy Fabric: How Fleece is Manufactured<\/h2>\n\n\n\n

The path of fleece through the process of getting a soft fabric is rather interesting. It may be simplified into steps “How fleece fabric is made<\/a><\/em><\/strong>“.<\/p>\n\n\n

\n
\"Step-by-step
\u201cHow fleece is manufactured \u2013 from plastic bottles to soft fabric.\u201d<\/strong><\/figcaption><\/figure>\n<\/div>\n\n\n
\n\n\n\n

Source Material: PET (Polyethylene Terephthalate)<\/h3>\n\n\n\n

PET is a form of plastic found in soda and water bottles where the beginning point of fleece starts. The manufacturers can use brand new polyester pellets or even utilize discarded plastic bottles. During recycling, bottles are gathered, separated and washed and then are reduced to flakes. The flakes are melted forming polyester chips that can be used as a foundation fleece.<\/p>\n\n\n\n

Extrusion<\/h3>\n\n\n\n

After polyester is made, it undergoes extrusion in which the melted substance is forced through extremely small spinnerets. The liquid polyester is forced through special metal nozzles with holes, called spinnerets, which makes the polymers into long hair-like filaments. These fine threads are gradually cooled and solidified to make strong fibers. The extruder process guarantees that the fibers are even in thickness, and are best suited to be converted into a yarn.<\/p>\n\n\n\n

Spinning<\/h3>\n\n\n\n

The resultant polyester filaments are then stretched, twisted in the spinning process. This adds strength, flexibility and durability to the fibers and enables them to stand up to everyday wear. The twisting resembles the appearance and texture of natural fibers although they are man-made. The process also aids in the regulation of the softness and the density of the end fleece material.<\/p>\n\n\n\n

Knitting<\/h3>\n\n\n\n

The polyester yarns are there knitted into big sheets of fabric. One of the factors that most influences the thickness, stretchiness or light weight of the fleece is knitting. Depending on the pattern, it can be single-knit lighter fleece or double-knit heavier, warmer varieties of fabric. This knitted cloth serves as the base which is then subjected to special process to give it the fluffy nature of fleece.<\/p>\n\n\n\n

Brushing<\/h3>\n\n\n\n

The step that makes fleece soft and cozy is brushing. In this process, the knitted fabric is wiped through large cylindrical brushes which have fine tooth of metal. The brushes spread the fibers on the surface and break them creating the lift away in a pile to create a plush insulating surface. This raised material traps air which enhances insulation and gives fleece great warmth, without increasing weight.<\/p>\n\n\n\n

Shearing<\/h3>\n\n\n\n

The brushed fleece is then subjected to shearing, in order to provide it with a smooth, even treatment. The raised fibers are then awkwardly edged to the same height such that the fabric material feels smooth and uniform all over the material. Shearing also prevents too much bulkiness or un evenness of the fabric. The final product is a deliciously smooth, warm and a very versatile fabric that can be used in jackets, blankets\u2026 and many other products.<\/p>\n\n\n\n

By doing this, an otherwise unfit plastic bottle is made into an acceptable breathable and warm textile. Fleece manufacturing demonstrates the capacity of human creativity to transform any ordinary waste into practical and comfortable materials.<\/p>\n\n\n\n

Types of Polyester Fleece<\/h2>\n\n\n\n

There are several varieties of polyester fleece<\/a><\/strong>, each suited to different uses. They differ by weight, pile length, or blend:<\/p>\n\n\n\n

Polar Fleece<\/h3>\n\n\n\n

Polar fleece<\/strong> is the classic, all-purpose fleece. It has a double-sided pile<\/strong> (brushed on both sides) for extra warmth. Polar fleece<\/a><\/strong> is ubiquitous in jackets, blankets, and linings. It\u2019s designed to mimic the insulating quality of wool but is lighter and easier to care for. Polar fleece was first developed in the 1970s (by Polartec) as a synthetic wool substitute. Today, any midweight fleece you see is often called \u201cpolar fleece.\u201d<\/p>\n\n\n\n

Microfleece<\/h3>\n\n\n\n

Microfleece<\/a><\/strong> is a lighter, thinner version of polar fleece. It is usually double-sided but with a very fine (short) pile. Microfleece is extremely soft and has a low profile \u2013 it doesn\u2019t puff up much. Because it weighs less (often under 6 ounces per square yard), microfleece is ideal for base layers and activewear. It insulates well for its weight and packs down small. However, it is not as warm as thicker fleeces. In short, microfleece is a \u201cmicro\u201d version of standard fleece \u2013 great for layering under a jacket or wearing during exercise.<\/p>\n\n\n\n

Sherpa Fleece<\/h3>\n\n\n\n

Sherpa fleece<\/strong> (also called faux-sherpa or boa fleece) mimics the look and feel of a sheep\u2019s wool fleece. It is made of polyester but has a curly, looped pile on one side. Sherpa is typically one<\/em> side fluffy like a sheep\u2019s wool, while the other side is a smooth knit. It is extremely soft, warm, and plush \u2013 picture the lining of a cozy winter coat. Sherpa fleece is very bulky and fluffy<\/strong>, making it excellent for hoodies, linings, and decorative trims. Fashionably, it has \u201cblown up\u201d in popularity for hats, vests, and jackets because of its very visible, wool-like texture. It tends to shed a bit of fluff with wear (though modern Sherpas are engineered to hold their pile).<\/p>\n\n\n\n

Blizzard Fleece<\/h3>\n\n\n\n

Blizzard fleece<\/a><\/strong> is warmer and also thicker than standard polar fleece. It has a fluffy velvet texture and is commonly applied to make no-sew blankets, winter garments, and outer clothes.<\/p>\n\n\n\n

All types of fleece carry specific advantages enabling manufacturers to target a broad consumer base-lightweight and sporty to heavyweight and warm.<\/p>\n\n\n\n

The Eco-Dilemma: The Issue of Microplastic<\/h2>\n\n\n\n

A controversial topic in fleece has to do with its effects on the environment.<\/p>\n\n\n\n

One of the positives is that fleece is produced using recycled bottles, and therefore less plastic is found in landfills. Brands such as Patagonia have brought this to industry, where it recycles millions of bottles into clothing. Our system of recycling lessens the need to produce virgin polyester and decreases pressure on the environment.<\/p>\n\n\n\n

The big problem with fleece however, is that when washed<\/a><\/strong>, microplastic fibers are shed. All these fibers flow within wastewater through systems, and find their way to rivers, oceans, and even through our food chain. It has been discovered that microplastics can be detrimental to the marine life and even human health.<\/p>\n\n\n\n

There are solutions to that:<\/p>\n\n\n\n
