nylon-and-polyester-fabrics
Nylon and polyester fabrics are made of synthetic materials and are therefore not biodegradable. They are often used in clothing and other textiles because they are durable and wrinkle-resistant. Nylon and polyester fabrics are also non-allergenic and can be machine-washed and dried.
Nylon
is a synthetic fiber that is made from petroleum. It is a thermoplastic material, which means it can be heated and molded into different shapes. Nylon is strong and durable, and is often used to make clothing, rope, and other fabrics.
Preparation of Nylon-6,6
Nylon-6,6 is a synthetic polymer composed of two monomers, hexamethylenediamine and adipic acid. These two monomers are combined in a reactor, and the mixture is heated to a temperature above the melting point of the polymer. The polymer is then extruded through a die, and the resulting filaments are drawn to increase their molecular weight. The filaments are then cut into pellets, which are packaged for sale.
Properties of Nylon
Nylon is a synthetic polymer composed of repeating units of the monomer called nylon 6,6. It is a tough, resilient material with a high melting point, and is used in a variety of applications, including ropes, fabrics, and engineering plastics. Nylon is produced by reacting adipic acid and hexamethylenediamine.
Uses of Nylon
Nylon is used in a variety of applications, including:
-thread for sewing
-fabric for clothing, upholstery, and tents
-ropes
-nets
-cables
-belts
-hoses
-tyres
-fishing line
-luggage
-life jackets
-car parts
-medical implants
Properties of Polyester Fibre
The physical and chemical properties of polyester fibre are as follows:
Polyester fibre is a synthetic polymer made from the combination of terephthalic acid and ethylene glycol.
It is a strong and durable fibre that is resistant to shrinking and stretching.
It is also resistant to most stains and microbes.
Polyester fibre is non-allergenic and does not cause skin irritation.
It is a thermoplastic fibre, which means it can be melted and reshaped multiple times.
It is also non-absorbent and does not hold moisture, making it a good choice for clothing and bedding that needs to stay dry.
Uses of Polyester Fibre
Polyester fibre is used in a wide range of products, including clothing, carpets, upholstery, and tyre cord.
Polyester
This product is made of 100% polyester.
Polyester is a synthetic fiber made from polyethylene terephthalate (PET), which is a type of thermoplastic polymer. It is often used to make clothing, as it is durable and does not wrinkle easily. Polyester can also be recycled.
Preparation of Polyester Resin
A mixture of 1,6-hexanediol, adipic acid and ethylene glycol was heated to 190° C. and then fed into a reactor equipped with a stirrer and a distillation column. The reactor was then heated to 240° C. and a monomer mixture comprising isophthalic acid and ethylene glycol was fed in at the same rate as the diol mixture. The reaction mixture was distilled and the distillate was collected in a receiver. The product was a polyester resin having an acid number of 9 and a molecular weight of about 10,000.
Properties of Polyester Fibre
Polyester fibre is a synthetic polymer.
It is made from ethylene terephthalate and isocyanate.
It is a lightweight, strong fibre that is resistant to shrinking and stretching.
It is commonly used to make clothing, upholstery, and carpets.
Uses of Polyester Fibre
There are many uses of polyester fibre. Some of the most common include:
-Making clothes: Polyester is often used to make clothes because it is durable and does not wrinkle easily. It is also a good insulator, which means it can keep you warm in the winter and cool in the summer.
-Making furniture: Polyester can be used to make furniture because it is strong and can withstand a lot of wear and tear.
-Making carpets: Polyester can be used to make carpets because it is soft and does not show dirt and dust easily.
-Making awnings: Polyester can be used to make awnings because it is waterproof and can withstand the sun and wind.
