Pre stretching refers to the practice of stretching a tennis string before you start to string a racquet with it. Rather than just cutting the string off the reel, threading it through the first grommet hole and starting to pull tension with the stringing machine, pre-stretching means you apply some tension to the string to change its properties.
Pros to Pre-Stretching: The main point for pre-stretching is to remove the coil memory of the string and make it a little easier to handle. This beneficial for difficult strings such as Polyester and Natural Gut.If you give it a nice pre-stretch that's going to reduce the coils and make it easier to work with, this is especially nice for natural gut if you give it a little bit of a pre-stretched that could prevent it from kinking during the stringing process which leads to premature breakage.
Tennis Warehouse shows you a few methods you can use to pre-stretch your tennis string, and also why pre-stretching is a good idea.
Pre-stretching is the practice of extending your tennis strings before you start stringing them on your racket. This process changes the thread properties through initial tension loss. Instead of going off the bat and applying pull tension by stringing using a stringing machine, preemptive extension captures the elastic feature of the tennis strings resulting in less tension loss over time.

WHAT IS PRESTRETCHING: Prestretching string is the act of stretching tennis string out of the package prior to installing into a tennis racket. WHAT TYPE OF STRING TO PRESTRETCH: Basically any tennis string can be prestretched but the benefits to prestretching generally apply to multifilament strings, natural gut and polyester based strings.
If the pre-stretch part of the process is eliminated, the string would have garbage for properties. Following the complete design of the manufacturing process makes it a string suitable for use in tennis. String 2: This string is offered for sale without having been pre-stretched during manufacture.
Pre-Stretched Poly. Conventional advice is to tension poly carefully with the slowest pull setting in the machine. That preserves the limited amount of elasticity in the string. ( link) The elasticity of nylon/mutifilaments allow them to stretch about 10-12%, natural gut about 7% and most polys only around 3-4%.
