PTRI laboratories operate on a first come, first served basis. The lead-time of testing services depends on the type of test and volume of samples submitted by the clients.

The Physical and Chemical Testing Laboratories conduct on-the-job training on fiber, yarn, fabric and garment testing. Interested students/ clients are advised to coordinate with the Technology Transfer and Promotion Staff on their requirements and for scheduling.

Clients must first communicate with our laboratories on the required specimen.

This is textile material from home grown fibers whose application ranges from functional and comfortable apparels and hometextiles to fashionable novelty fabrics and accessories. This is manufactured locally either by handloom or powerloom weaving in pure from or in blends with other textile fibers.

The fibers are pretreated to make them spinnable into yarns and eventually woven into fabrics.

There are five types of fiber pretreatment.

1. Digestion - a process of high temperature and pressure with certain chemicals makes the fiber softer and more pliable by lignin/ hemicellulose reduction.

2. Woolenization - a process of imparting wool-like properties such as feel, fullness, and crimp on the fiber for a better fiber-to-fiber cohesion during carding, silver formation and subsequent processes.

3. Degumming - a process that removes the natural gums contained in a fiber by subjecting it to dilute solution of alkali at elevated temperature in the absence of air. The process is needed to separate the individual fibers and leave them in a soft clean state with their strength and other characteristics intact.

4. Chemical softening - the application of chemical softening agent on the degummed fiber to impart softness property.

5. Mechanical softening - the process is done with the use of a softening machine by passing the dry fibers between the helical of grooved rollers for 2 to 3 times.

Dyestuffs or simply dyes are colored bodies of soluble nature, usually complex derivatives of carbon, capable of imparting permanent color to the textile materials.

Natural dyes are obtained from plants, animals and minerals e.g. indigo, madder, yellow ginger, logwood, cochineal, kermes, alum and other metallic salts.

Synthetic dyes on the other hand, are mostly coal-tar derivatives, e.g. mauve, magenta, sulphur blue, naphtol yellow, etc.
