Modification of polyamide fibers by forming an interpenetrating polymeric system in the surface layer
- 21 Downloads
The proposed method of modifying a polyamide yarn is based on the formation of an interpenetrating polymeric network in its surface layer.
The optimum IPN content of a yarn for the system examined is 2–6 or 21–23% by wt.
The presence of an IPN in the surface layer of a fiber ensures an increase in strength and heat-resistance, and in the adhesive strength of the bond with a polymeric matrix.
