METHOD FOR MODIFICATION OF POLYAMIDE FIBRES Russian patent published in 2010 - IPC D06M13/447 D06M13/325 D06M15/05 C09K21/10 C09K21/12 D06M101/34 

FIELD: textile industry.

SUBSTANCE: treatment is carried out with composition, which contains the following components in wt parts: 20 borate of methyl phosphite, 1.3 of triethanolamine, 80 of water and 0.20-0.65 of 1% water solution of carboxymethylcellulose at 20°C for 1 min. Fibres are dried on air and thermostatted at 100°C for 30 min.

EFFECT: improved fire-resistance, water-resistance, strength and resistance to thermal-oxidative destruction of polyamide fibres, increased strength of polyamide cord joint to rubber on the basis of chloroprene rubber.
