STRING CONSTRUCTION

Details of Different String Constructions

The huge number of string available nowadays can be very daunting, below we provide details of the most commonly used string constructions for tennis, squash and badminton. There are variations within these groups, but they provide an overview of the different constructions available.

Monofilament - Originally associated with low cost nylons, nowadays it represents a solid construction blending polyester or polyether prodiving a string with very good durability and a more lovely feel than a kevlar string.

Solid Core with Single Wrap - The most common string construction. The solid core provides durability and reduces tension loss, whilst the outer wrap protects the core and improves the playability.

Solid Core with Multi Wrap - The extra wrap provides a 'softer' feel and better playability, however the thinner core does mean than durability is reduced.

Multifilament - Very similar in construction to Natural Gut, this coreless type of string is made up of multifibres and coated for protection. It has excellent playability but tends to lose tension more quickly than string with a centre core. A 10% increase in stringing tension or pre-stretching is recommended.

Composite - This combination of nylon and aramid fibres (Kevlar, Technora, etc.) increases durability whilst not detracting from playability.

Hybrid - The combination of a very durable main string (up and down) (aramid fibre or monofilament) and a more elastic cross string (synthetic gut) is ideal for frequent string breakers. Many players now choose to create their own hybrids to match their specific needs.

Textured - The same construction as a solid core with single wrap but with added outer wrap (or wraps) giving the string a textured surface enabling more grip on the ball (good for spin).

Natural Gut - The ultimate in playability and still favoured by some of the world's leading tennis players. Either cow or sheep gut is used to make a string with excellent power and feel. The price means it has a restricted market and extra care needs to be taken to avoid premature breakage.

Kevlar / Aramid Fibre - The ultimate in durability. Kevlar belongs to the family of aramids and is the strongest and toughest string on the market.

Independent Tennis String Survey Results - 2009

Over the past few years, polyester strings have become more and more popular – they offer very good durability, good power and excellent spin capability. However, they are typically hard on the arm (can cause / aggravate elbow problems) and lose tension relatively quickly. The recommended strings below were based on a survey in which polyester and non-polyester strings were considered separately. For further details and full results, please take a look at the StringForum.net Website (StringForum.net).
