Brief
The brief has asked for a Waterproof Jacket design for the company Tresspass. This design is to be created for the intention of being sold to women. As this is a design for a sportwear brand the garment will be designed to fit an activewear jacket.
Tresspass jackets tend to have additional qualities that everyday jackets may not have such as added wind proofing or breathability depending on what the intended use for the jacket design is within the activewear category.
The target market for these jackets are aimed at women who are around 20 onwards with a mid income who are looking for high quality activewear which can be used for a variety of things such as hiking, cycling, or running. They are looking for a high quality product which will withstand any weather and last a long time.
The price range for tresspass jackets start at £43 at the cheapest product and end at £250 with the most expensive product.

Fabric Choices
The most popular fabrics seen on the trespass website for waterproof jackets are polyester and poly amine also known as Nylon. For my design I have chosen to make the main fabric 100% polyester with a PU coating and my lining 100% polyester. The thread will be also be made of polyester.
Polyester is a synthetic, woven fibre created by DuPoint in 1929 and released for use in 1953. Polyester is very well known as being a strong and resilient fibre which is ideal for an active wear jacket as it will resist pull and tears. It is a hydrophobic fibre so will repel water from its surface. It has low absorbency so will dry extremely quickly making it ideal for an active wear jacket as it can easily withstand the rain and provide protection to the wearer. I have chosen to add a lining onto the jacket shell as my design has a hood and I want it to look finished and neat. Many outerwear jackets are made of a polyester fabric with a strengthening coating as well as a lining.
I have chosen to use a synthetic fibre instead of a natural fibre due to natural fibres such as cotton, linen and wool have a high absorbency so would not be waterproof. Although acrylic has hydrophobic properties it is commonly used as an artificial wool and has to be blended with another fibre such as wool which would reduce its hydrophobic properties, this is why i chose polyester over acrylic fibres.
The downside to polyester is that when burned can leave residue which can burn the wearer so a Keep Away From Fire warning must be included on the care label. In order to add additional strength to the fabric a PU coating will also be added which is commonly used in outerwear jackets.
PU stands for polyurethane and is a coating commonly used in active wear. This is due to it not only strengthening the fabric to make it more resistant to tears and damage but also adds a waterproof coating to the fabric while still allowing the fabric to move freely. The fabric can be coated once or several times in order to add more of a waterproof element to the garment. Since polyester is naturally a hydrophobic fabric I will be adding a single layer of PU in order to ensure the garment is both strong and waterproof but isn’t bulky or heavy at the same time.
When designing my garment I have taken into consideration how the garment seams will be joined together in order to create a tight seal which water cant seep through. This is done through a technique called seam taping or seam sealing.
Seam taping is when waterproof tape is applied over the seams of the garment. This is done as the stitches of a seam creates a tiny hole where water can seep through. The seam tape is bonded to the seam with a high heat and seals the holes created by the sewing needle. I will be fully seam sealing my garment to ensure there are no points of weakness where the water can permeate the garment.
I have chosen to use a heavy duty polyester thread in my garment due to the strength and waterproof properties of the fibre. As the thread will be used to sew a jacket a heavy duty thread will be more suitable as it will be easier to sew a fabric with flame retardant and PU coating on it.
Aftercare
Washing
A synthetic wash should be used as jacket is made of polyester. Use cleaner designed for waterproof outwear. Wash at 30 degrees to prevent damage to PU coating.
Bleaching
Do not bleach as polyester does not take to bleaching
Ironing
Do not iron as polyester doesn’t tend to crease and heat can damage the PU finish.
Dry Cleaning
May be dry cleaned
Tumble Dry
Do not tumble dry in order to protect PU coating.
Hang Dry
hang/ line dry as garment will not become distorted.

Legislation
The Textile Products (Labelling and Fibre Composition) Regulations 2012
This regulation will ensure the designed garment will carry a label which will state the fibre content of the garment and all individual components will have fibre composition shown on the label with the common name in order not to confuse the consumer. The label must be easy to read and durable as well as easy to access. As there is a finish in the form of a coating which makes up more than 7% of the garment this must be stated on the label.
Trade Marks Act 1994
As trespass is a trademark with a registered logo they are entitled to be protected under the Trade Marks Act. This act will ensure that there product will not be duplicated and sold by third parties. This applies to both their designs and logo. This will protect the brand as well as consumers from third party sellers trying to imitate their products either through products or packaging.
