Description
На жгут в зоне раст жени I нанос т капли 3%-ного водного раствора целлюла- зы посредством капельницы 2 (см.фиг.1) или игольчатого валика и ванны с раствором (см.фиг.2).Drops of a 3% aqueous solution of cellulase are applied to the harness in the stretch zone I using dropper 2 (see Fig. 1) or a needle roller and a bath with a solution (see Fig. 2).
Нанос т капли ha жгут сразу же после его вхождени в зону раст жени , чтобы в течение 3 - 4 с (времени Т движени жгута через зону i) целлюлаза оказывала воздействие на нити.A drop of ha is applied immediately after it enters the stretching zone, so that for 3-4 s (time of movement of the tow through zone i), cellulase affects the filaments.
Например, если длина зоны I L 1,5 м, Т 4 с, обща выт жка в зонах II равна 6, то скорость движени жгута в зонеFor example, if the zone length I L is 1.5 m, T 4 s, the total exhaust in zones II is 6, then the speed of the harness in the zone
I V 0,375 м/с, скорость выпускаI V 0,375 m / s, the speed of release
ленты Ул 0,375-6-60 135 м/мин (размеры зоны I, обща выт жка, скорости вз ты реальными дл ленточно-разрывных машин).tapes of UL 0.375-6-60 135 m / min (dimensions of zone I, total stretch, speeds are real for tape-breaking machines).
При необходимости увеличить выдержку , т.е. промежутки времени Т, нужно увеличить L, как показано, например, на фиг.З, т.е. путем введени направл ющих валиков 3-5, огибаемых жгутом.If necessary, increase the shutter speed, i.e. periods of time T, it is necessary to increase L, as shown, for example, in FIG. 3, i.e. by inserting guide rollers 3-5, circumscribed by a tow.
В предлагаемом способе происход т уменьшение прочности нитей в местах нанесени фермента и последующий разрыв нитей по этим местам, после чего формируетс штапелированна лента.In the proposed method, a decrease in the strength of the filaments occurs at the sites where the enzyme is applied and the subsequent breakage of the filaments in these places, after which the stapled tape is formed.
Целлюлаза обладает специфической активностью к гидратцеллюлозе, основному веществу вискозных нитей. Фермент целлюлаза способен разрывать внутримолекул рные св зи в молекуле гидратцеллюлозы, что вл етс причиной уменьшени прочности нити в местах нанесени фермента.Cellulase has a specific activity to hydrate cellulose, the main substance of viscose yarn. The cellulase enzyme is capable of breaking intramolecular bonds in the cellulose hydrate molecule, which causes a decrease in the strength of the yarn at the sites where the enzyme is applied.
Приведенные ниже данные позвол ют судить об изменении качества ленты при использовании различных значений концентрации водного раствора целлю- лазы:The following data allows you to judge the quality of the tape when using different concentrations of an aqueous solution of cellulase:

Предлагаемый способ позвол ет уменьшить усили разрыва нитей при штапелиро- вании жгута и улучшить структуру волокна. Объ сн етс это ослаблением участков нитей в местах нанесени на них капель цел- люлазы и последующим разрывом нитей поThe proposed method makes it possible to reduce the breaking force of the filaments when stapling the tow and improve the fiber structure. This is due to the weakening of sections of the filaments in the places where cellulase drops are applied to them and the subsequent rupture of the filaments.
этим участкам. Эксперименты показали, что прочность участков нитей, на которые попала целлюлаза, уже через 3 - 4 с после нанесени фермента уменьшаетс примерно в два раза по сравнению с теми участками, наthese sites. Experiments have shown that the strength of the sections of the filaments on which cellulase has fallen decreases 3–4 s after the application of the enzyme approximately two times as compared with those areas
которые целлюлаза не попала.which cellulase missed.
