Blending Nomex® with cotton improves its affordability and serviceability. Because cotton is a highly flammable fiber, Nomex®/cotton blend fabrics containing more than 20% cotton require flame-retardant treatment. In this research, combination of a hydroxyl functional organophosphorus oligmer (HFPO) and 1,2,3,4-butanetetracarboxylic acid (BTCA) was used for flame retardant finishing of the 65/3...

The first stage of the RTM process concerns the preforming of the part. During the preforming of multilayered reinforcements, frictions between the plies occur. An experimental device designed to analyse the ply/ply, ply/tool and yarn/yarn frictions has been set up. Specific contact behaviour for ply/ply friction is directly related to shocks taking place between overhanging yarns of each sampl...

In gen(-, ral ,a seam may f ai I as a result of longitudinal or transverse loading. Previous workers have reported transverse seam strength to be a prime requirement in most cases of Joining woven fabrics by the means of sewn seams. Transverse seam breaks can be divided into two types: Type I in which only the sewinq thread breaks (with Lhe fabric undamaged); and Irype II in which only the fabr...

“I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to their colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives...
