Description
в месте входа пр жи i;f 80-200С, а в месте выхода Ц, 100-210 С, т.е. соответственно на 5-100 С выше чем Tj . Врем же пребывани пр жи на выт жном ролике 5 0,005-2 с, предпочтительно 0,3-1 с. На усадочной части выт жных роликов 4 и 5 пр вод т первую ступень усадки 1-10%, а усадку второй ступени 1-10% осущесвл ют между выт жными роликами 4 и и нат жной парой 6 узла 7 приемки/ скорость которого 200-1200 м/мин. Таким образом,немедленно после выт жки пр жу подвергают двухступенчатой плавной усадке в короткий период времени, что приводит к низкой термической усадке пр жи и повышени ее качества. Получаема полиэфирна пр жа пригодна дл использовани в качестве рыболовных сетей,арматуры дл резиновой продукции и парусов хт, кроме того, может использоватьс в комбинации с волокнами, обладающими большой усадкой, при производстве объемных тканных изделий . .at the entry point of yarn i; f 80-200C, and at the exit point C, 100-210 С, i.e. accordingly, 5-100 С higher than Tj. The residence time of the yarn on the stretch roller 5 is 0.005-2 seconds, preferably 0.3-1 seconds. On the shrinkable part of the exhaust rollers 4 and 5, the first stage of shrinkage is 1-10%, and the second stage 1-10% shrinks between the exhaust rollers 4 and and the tension pair 6 of the receiving unit 7 / speed of 200-1200 m / min Thus, immediately after stretching, the yarn is subjected to a two-step smooth shrinkage in a short period of time, which leads to a low thermal shrinkage of the yarn and an increase in its quality. The resulting polyester yarn is suitable for use as fishing nets, rubber fittings, and xt sails, and can also be used in combination with highly shrinkable fibers in the production of bulky woven products. .
Приме,р 1. Невыт нута пр жаиз полиэтилентерефталата обработана при следующих услови х: предварительное нат жение 1,0045, температура поверхности ролика 2 поданадей пары .Количество витков пр жи на подающей паре и выт жной паре 6, отношение выт жки 5,0, температура пр жи на входной части выт жного ролика , а на выходной части 22(f С, перва усадка 7%, втора усадка - 5%, температура поверхности нат жного ролика 6 около , а его скорость ,6013 м/мин, Пример 2. Аналогичен при-i меру 1, отличаетс только тем, что вторую усадку не провод т.Apply, p 1. The polyethylene terephthalate precursor is treated under the following conditions: preload 1.0045, the surface temperature of the roller 2 is applied to the pair. The number of turns of the yarn on the feed pair and the exhaust pair 6, stretch ratio 5.0, the yarn temperature at the inlet part of the exhaust roller, and at the outlet part 22 (f C, first shrinkage 7%, second shrinkage 5%, surface temperature of the tension roller 6 about, and its speed, 6013 m / min, Example 2. Similar to measure i, i, differs only in that the second shrinkage is not performed.

Разрывна прочФормула изобретени Explosive Proof the Invention Formula
1.Способ получени низкоусадочной полиэфирной пр жи, заключак цийс в термовыт гивании, проведении двухступенчатой усадки при температуре первой ступени усадки, превышающей тег шературу термовыт жки, и приемке пр жи, отличающийс тем, что, с целью повышени качества пр жи , первую ступень усадки провод т на усадочной части выт жной пары при непрерывно или ступенчато повышающейс температуре, а усадку второй ступени осуществл ют между выт жной парой и нат жным роликом узла приемк1. A method of producing low shrink polyester yarn, concluded with thermo pulling, performing a two-step shrinkage at the temperature of the first shrinking stage, exceeding the sherature pattern of the thermo pulling, and accepting the yarn, characterized in that, in order to improve the quality of the yarn, the first step of shrinking is carried out on the shrink part of the exhaust pair with a continuously or stepwise increase in temperature, and the second step shrinks between the exhaust pair and the tension roller of the receiving unit
2.Способ по П.1, о тли ч ающ и и с тем, что скорость приемного узла 200-1200 м/мин.2. The method according to Claim 1, which is based on the fact that the speed of the receiving unit is 200-1200 m / min.
