1. Leather      Leather is a fabric made from animal skins that have been tanned. Some common sources of genuine leather material are cow, deer, snake, and alligator. You'll find leather most often in handbags, crossbody bags, and backpacks.Advantages And Disadvantages Of Leather Bags FabricsAdvantages:Durability: Leather is highly durable and an ideal fabric for bags that will see lots of use over the years.Abrasion Resistance: When treated and well cared for, leather will remain free of scuffs and scratches.Fire Resistance: If treated, leather is resistant to fire.Water Resistance: Leather wicks away water and remain unscathed by moisture – provided it’s treated.Flexibility: Leather is flexible and malleable to a mold, making it an excellent material for a structured bag.Longevity: Leather will last many years as long as it’s taken care of.Disadvantages:High Cost: Leather is by far one of the most expensive bag fabrics. This disadvantage can deter companies from using leather altogether.Not Vegan Friendly: If your customer base is primarily vegan or environmentally conscious, then leather fabric may not be a great choice for your bag line.2.   Polyester      Polyester is another type of thermoplastic derived from petroleum. The process of making polyester fabric begins with melting down ethylene glycol from the petroleum along with purified terephthalic. Together, these two substances are from polyethylene terephthalate (PET), from which polyester manufacturers form fibers and weave them together into a fabric. See also Recycled Polyester(rPET).      You'll often find polyester in backpacks and duffel bags.Advantages And Disadvantages Of Leather Bags FabricsAdvantages:Elasticity: Polyester is an elastic material that has some stretch, yet still retains its shape.Durability: Polyester fabric is strong, which is why it’s so popular in backpacks and duffel bags. You can rough it with a bag made of this material and it will hold up.Moisture Resistance: Like nylon, polyester wicks away moisture and dries quickly.Texture Variety: Polyester is available in a wide variety of textures, from coarse to smooth like satin.Drapability: Polyester is easy to shape and will keep that shape.Disadvantages:Breathability: Similar to nylon, polyester fibers are constructed closely together. This reduces the material’s breathability, so anything kept inside a polyester bag is at risk of becoming too hot or humid if it’s exposed to a hot or humid environment.Flammability: Polyester is flammable, which means that polyester bag owners should take extra caution to make sure they never put their bag close to a fire.Environment-killer: Processing virgin polyester has a tremendous negative effect on the planet.3. Nylon      Nylon is a type of thermoplastic that is usually sourced from petroleum. It is melted down and processed into fibers, and those fibers make up the fabric that we use for several different bag types, especially backpacks and duffel bags.Advantages And Disadvantages Of Leather Bags FabricsAdvantages:Elasticity: Nylon is somewhat elastic, and elasticity is always a great quality in material for a backpack or duffel bag. In bag form, it allows the fabric to stretch and bulge outward to accommodate a large number of objects, even if the objects are oddly shaped. Yet at the end of the day, it will still retain its original shape.Durability: Nylon is a sturdy fabric that will last a long time without wearing out. Consumers get their money’s worth in terms of long use when they buy a bag made of nylon fabric.Clean: Nylon is easy to keep clean. It doesn’t cling to dirt or other grime, so if a nylon bag gets dirty, you can just wipe it clean with a wet cloth. You can also wash nylon fabric in cold water, and it won’t lose its shape.Moisture Resistance: Nylon repels water for the most part, and if any part of it absorbs water, it will dry quickly. This makes it a smart bag fabric choice for people who are often outside or frequently visit places where they are likely to get wet, like a pool or a beach.Drapability: Nylon drapes well, meaning it can be molded to the manufacturer or brand’s desired shape.Disadvantages:Breathability: One of the substances that make up nylon is closed construction filaments. These are tightly packed filaments of plastic that trap heat inside the fabric. This can be a problem during hot weather if you want to use the nylon bag to carry perishable food or electronics that could overheat.4. Canvas      Canvas is a type of woven fabric that is made from cotton or linen fibers. It can also be made with polyvinyl chloride (PVC). Provided it's made from cotton or linen or another natural source, like hemp, it's considered a natural fabric. Canvas is a common material for backpacks, duffel bags, and totes, due to its many advantages as a bag fabric.Advantages And Disadvantages Of Leather Bags FabricsAdvantages:Durability: Canvas is a highly durable and sturdy material. A canvas that has been treated with chemicals will last a long time without wearing out. This makes it a great material for a bag that will get a lot of use and carry around heavy objects.Washability: Canvas is washable and easy to clean.Color Printing: The natural off-white color of canvas is, frankly, a great canvas. It holds color printing well, so brands can easily customize bags made of this material.Disadvantages:Weight: Canvas is a heavy fabric, especially when it gets humid/wet. This can be a problem if you’re carrying the bag outside where it could get rained on or splashed with puddle water.5. Felt      Felt is a soft, but dense fabric made from natural fibers, typically wool.      There are a few different methods of creating felt, but the most popular type for bags – woven felt – is made by weaving strands of wool into cloth, and then compressing the cloth while it is exposed to moisture. The compression along with the moisture causes the fibers to interlock and form a closely connected unit.      Felt is most often used in handbags, crossbody bags, and backpacks. It can be used as the main fabric, or as internal reinforcement.Advantages And Disadvantages Of Leather Bags FabricsAdvantages:Durability: Thanks to the strength and resiliency of its interlocking wool fibers, felt is quite durable. It will stand up to a lot of wear and tear, which is important for a bag.Availability: Felt is available in many different colors and various thicknesses, so companies will not feel limited by their choices in this fabric.Lightness: Even though felt feels warm, it’s incredibly lightweight. This is another quality that makes it a great material for a bag, which should be designed to be carried around for long periods of time.Disadvantages:Elasticity: Felt doesn’t have much stretch or give to it.Shrinkage: Felt is liable to shrink if it’s not washed properly.6. Recycled PVB Leather      Recycled PVB leather is a new type of synthetic leather that is not made using animal hides, but rather a material called polyvinyl butyral (PVB). PVB is used primarily as a resin in vehicle windshields and windows. It strengthens the glass and protects it during accidents. However, it’s difficult to reuse in windshields, so some fabric manufacturers started recycling it into faux leather.Advantages And Disadvantages Of Leather Bags FabricsAdvantages:Elasticity: Recycled PVB leather is highly elastic. It can be molded into a particular shape for a bag, and it will continue to keep that shape throughout its lifetime.Abrasion Resistance: Like real leather, recycled PVB leather is resistant to abrasions. This prevents it from looking scuffed and scratched, and therefore cheap over time.Water Resistance: Recycled PVB leather does not absorb moisture, rather it wicks water and liquid droplets away from its surface.Fading Resistance: The color of recycled PVB leather doesn’t easily or quickly fade.Sustainability: The process used to synthesize recycled PVB is better for the environment and more sustainable. During the manufacturing process, the factory recycles existing material and transforms it into usable material with a smaller carbon footprint than real leather.Disadvantages:Durability: Recycled PVB leather is not quite as durable as the real kind. However, it’s close enough that it’s still a comparable material. It’s also a great deal stronger and more long-lasting than other faux leathers.Conclusion      There are many choices of fabrics for bags, which need to be considered comprehensively.

Recycled polyethylene terephthalate (rPET) might not be something that pops up in everyday conversation, but it’s important to know a bit about it if you want to make the switch to a more sustainable lifestyle.Australians are getting more waste conscious. The latest statistics from 2009 indicate that 94 per cent of households recycled or reused their plastic bottles. Furthermore, 93 per cent recycled or reused glass, 91 per cent chucked their cans in the recycling bin, and 90 per cent did the same for plastic bags.Of particular note is the amount of plastic bottles that are recycled. While reducing waste altogether is one noble goal, it’s still important to recycle what you do use.Recycled material is actually used for a number of handy things. Many drink bottles, such as soft drink or water bottles, are made out of a material called polyethylene terephthalate (PET), and mountains of these are used and thrown away every year.However, luckily for us, these old discarded bottles can be used to create something new. Introducing rPET: when recycled, bottles made of PET are cleaned, sorted and crushed into miniscule flakes. Then through the magic of science, these flakes are heating to melting point, and transformed into yarn.This yarn is then used to make up fabric for items such as reusable shopping bags. This means fewer bottles end up buried in landfill. Plus, the process of making products from rPET consumes a lot less energy and is less resource intensive than making products from virgin materials.Look out for other products made from recycled materials and make the most of what can be created from rPET.Our company designed some new style of bags which are made by rPET.We would love the world to be a better place because of your choose our company.This is our company's official website:https://sofiebag.comContact us NOW !
