Abstract

Wearing hats and caps in sunny areas to protect from the sun's rays is frequent in hot areas or as a

requirement for fashion lines, especially in summer and spring times. The idea of this research came to help many workers in the fields of construction, contracting, iron, and glass industry, as workers in these fields are constantly exposed to the sun and heat, as there is a boom in these fields in Egypt and the Arab countries. A number of fabrics were

woven, their permeability properties were measured, and the extent to which they protected hair

from airborne dust and sunlight, by measuring the porosity of the tested fabrics. The best tested

fabrics for permeability and porosity were selected and coated with polyacrylate copolymer to

increase protection from the sun's rays by measuring the sun protection factor (UPF) using diffuse

transmission spectrophotometer. Cap was designed using Gerber software. The results showed that

choosing the appropriate fabrics in the manufacture of hats and caps prevents damage to the hair.
