FIELD: textile industry; production of the polyester fibers helically-conjugated balls. ^ SUBSTANCE: the invention is pertaining to the field of textile industry, in particular, to production of the polyester fibers helically-conjugated balls, which may be used as the filler in such products, as the blankets, cushions, mattresses, cushions for the seats, backrests for the seats, coverlets, sleeping bags, the soft furniture and the soft toys, and also as the heat insulation for clothing and as the protective filler for the working clothes of different designation, including the heat-resistant clothes, moisture protective clothes, anti-gas protective clothes and cold protective clothes. The protective filler made out of the polyester fiber balls represents the helically-conjugated balls with the nominal linear density of 0.7- 0.9 tex, the nominal length of straightening of 25-39 mm, the twisted degree of 23.0-27.0 %,the twist stability of 50-95 %, the volume mass of 2.0-7.0 kg/m3, an elongation at the break of 40-50 %, the relaxation properties of the fibers at their compression in the mass of 75-80 %, the normalized humidity of 1.0-2.0 % and the specific breaking loading of 38-40 sn/tex. The technical result of the invention is the helically-conjugated balls reduced friction between the individual coils {balls} with the possibility of more free and independent movement and recovery of all their properties. ^ EFFECT: the invention ensures the helically-conjugated balls reduced friction between the individual coils and balls with the possibility of more free and independent movement with recovery of all their properties. |
