Nylon tyre cord is made from high tenacity continuous filament yarn by twisting and plying. There are two major types of nylons used as tyre cord, i. The properties of nylon-6 and nylon-6,6 vary marginally and are controlled by the manufacturing process, type of stabilisers and additives used.

In India only nylon-6 is produced commercially for tyre cord. The denier per filament is 6. The other materials used as tyre cord are cotton, rayon, polyester, fibre glass, steel,aromatic polyamides.

Each of these materials has its own merits and demerits. The major criteria for acceptance of any material in tyre are its tensile strength, dimensional stability, durability, thermal stability, hysteresis and adhesion. Tests and actual application conditions have shown that although other cord materials meet one or more specific requirements, nylon by and large meets the desirable requirements for almost all the performance criteria.

The tyre cord fabric provides the tyre its fundamental properties such as shape, size, load carrying capacity, abrasion resistance, fatigue resistance, etc. A tyre is a composite of cord and rubber.

There are three varieties of tyres viz. They differ in the way the tyre fabric plies are laid inside the tyre. The manufacturing process for nylon-6 tyre cord can be broadly divided into following production steps: Nylon is made by polymerisation of caprolactam with certain additives like amino acids and dicarboxylic acid salts and certain heat stabiliser such as copper based organic compounds.

The polymerisation process involves ring opening polycondensation and polyaddition reactions. All the three polymerisation reaction steps are equilibrium reactions.

A typical process of polymerisation of nylon can be either a batch or a continuous process. The continuous process, developed after the batch process was commercialised, offers simplicity of design, ease of operation and control and high capacity. An optimal polymerisation process would involve two stages, wherein, the first stage involves pressure at high initial water concentration.

In the second stage a rapid transition from high water content to a low water content is achieved by release of pressure and subsequent application of vacuum. Industrial grade nylon-6 with relative viscosity 3. The nylon chips are washed to remove water soluble impurities and then dried.

The process maybe batch or continuous. The polymer chips are melt in extruder. The molten polymer is then spun through a spinnerette.

The molten filaments are quenched or cooled by a laminar flow of air. The spin finish is applied on filament and then wound on spin bobbins and drawn to make tyre yarns.

In the conventional process, the spinning and drawing was done in two steps. In the spin-draw process, a step is reduced compared to 2-step conventional process. As a consequence, some sources of process disturbances are eliminated which results in improved yarn uniformity.

Nylon tyre yarns are then twisted in S or Z direction and plied having 2 or 3 plies to form a tyre cord. Depending on the quality of waste, any of the following method may be used for recycling of nylon waste.

Direct use of fibre waste RegrannulationPolymer Powderi without melting ii with melting. Recovery of amino caproic acid. The first three processes require relatively purer and undegraded form of waste. Amongst the last two, caprolactam recovery is mostly adopted by Indian industry due to ease of purification of recovered caprolactam.

For nylon-6, the only major raw material required is caprolactam.Full Catalog of Tires | Yokohama TireTop Performance Tires · Find Tires That Fit.
