Abstract
Procedeul pentru prepararea de fibre sintetice din topituri si dispozitivul de realizare a acestuia, conform inventiei, este utilizat în industria obtinerii de fibre chimice din topituri si consta în micsorarea distantei dintre punctul de ies8ire a topiturii din placa de filare si punctul de contact cu lichidul de rasucire si este stabilit la o caloare de cel mult y=50x50mm în care x reprezinta distanta nominala, indicata în mm, a orificiilor placii de filetat, în tim ce tensiunea interfaciala dintre lichidul de racire si fasciculul de topitura este dimuniata sub tensiunea nominala a suprafetei dee separatie dintre apa distilata la temepartura de 20 degree C si fasciculul de topitura considerat, fiind obtinute fire nelaminate cu finete de 2...1000dtex, care, apoi, practic, sînt laminate într-un mod în sine cunoscut. Dispozitivul pentru realizarea procedeului este alcatuit, conform inventiei, dintr-un rezervor cu lichid de racire a instalatiei de racire, montat fix în raport cu placa de filar e, care este prevazut cu un regulator de nivel sau rezervorul cu lichidul de racire este montat la un dispozitiv de ridicat, în felul acesta lichidul de racire are o capacitate termica cu mult mai mare si în consecinta, o temperatura mult mai regula ta decat curentul de gaze întrebuintat pîna acum în scopul racirii, în felul acesta sînt asigurate uniformitatea structurii fiibrelor si proprietatile mecanice omogene ale fibrelor; prepararea fibrelor fialment, unde valorile de difuzare s-au formatavantajos la fiecare proprietate a fibrei; racirea rapida influenteaza în mod favorabil structura fibrelor, prin modificarea temeparturii baii, care potrivi scoAccording to the invention, the process for preparing synthetic melt fibers and the present invention is used in the melt chemical industry to reduce the distance between the melt exit point of the spinning plate and the liquid contact point twist and is set to a caloric maximum of y = 50x50mm in which x is the nominal distance, indicated in mm, of the threads of the threaded plate, while the interfacial tension between the coolant and the melt beam is dimmed below the nominal surface tension of the separation between the distilled water at the temperature of 20 ° C and the considered melting beam, thus obtaining non-laminated wires with fines of 2 ... 1000dtex, which are then practically rolled in a manner known per se. According to the invention, the device for carrying out the process consists of a coolant coolant reservoir fixedly mounted with respect to the filler plate which is provided with a level regulator or the coolant tank is mounted at a lifting device, in which way the cooling liquid has a much higher heat capacity and consequently a much more normal temperature than the gas stream used so far for cooling purposes, thus ensuring the uniformity of the structure of the beams and the properties homogeneous mechanical mechanics of the fibers; the preparation of fialment fibers, where the diffusion values have been rendered advantageous for each property of the fiber; rapid cooling favorably influences the structure of the fibers by changing the temperature of the bath,
