The Congress passed R.A. 4086 "An act to promote the textile industry of the Philippines by exempting, under certain conditions, importation of needed materials, chemicals, dyestuffs and spare parts and the subsequent manufacture and sale of products derived therefrom, from duties and taxes, by creating a special fund for vital research and for other purposes". The law created a special textile research fund, which was derived from one percent of the gross sales of textile manufactures that registered for tax exemptions from 1964-1970.

The National Science and Development Board (NSDB) approved the formulation of a textile research program with functions, powers and duties in accordance with the objectives of R.A. 4086.

The NSDB formally established the PTRI as the agency to undertake the textile research program.

The PTRI became one of NSDB's eight regular agencies by virtue of Presidential Decree No. 1 "Implementing the integrated reorganization plan of the executive branch of the Philippine government". Policies were formulated by an advisory committee composed of Textile Manufacturers of the Philippines (TMAP), Department of Agriculture and Natural Resources (DANR) and NSDB.

The PTRI was transferred from NSDB to the Ministry of Trade and Industry (MTI) by virtue of Executive Order No. 700.

By virtue of Executive Order No. 128 the National Science and Technology Authority (NSTA), then NSDB was reorganized and provided among others, the return of PTRI from MTI to the NSTA now the Department of Science and Technology.
