Abstract

Procedimento di mercerizzazione in continuo idoneo ad eseguire il trattamento di mercerizzazione su una pluralità di fili (11) di fibre di poliestere svolgentisi autonomi con continuità e l'un l'altro paralleli, da uno (12) o più (112, 212) subbi di alimentazione, detta pluralità di fili (11) venendo sottoposta in successione alle seguenti fasi operative: impregnazione (13) per immersione in bagno in almeno una vasca (22) contenente un bagno di soda caustica riscaldata; prima asciugatura (14) in forno (31a) a circolazione d'aria calda; vaporizzazione (15) con vapor d'acqua; neutralizzazione con lavaggio a caldo, detta neutralizzazione comprendendo un primo stadio di lavaggio in acqua calda (16) per immersione in almeno una vasca (22) contenente un bagno di acqua calda, un secondo stadio di neutralizzazione (17) vera e propria per immersione in almeno una vasca (22) contenente un bagno acido, e un terzo stadio di risciacquo (18) per immersione in almeno una vasca (22) contenente un bagno di acqua fredda; seconda asciugatura (19) finale in forno (31b) a circolazione d'aria calda; detti fili (11), come uscenti dalla seconda asciugatura (19) finale, venendo avvolti in almeno un subbio di raccolta (39).Impianto di mercerizzazione in continuo idoneo ad eseguire il trattamento di mercerizzazione su una pluralità di fili (11) di fibre di poliestere svolgentisi con continuità e l'un l'altro paralleli da uno (12) o più (112, 212) subbi di alimentazione, detto impianto (20) adottando il procedimento (10) di cui sopra, comprendendo i seguenti gruppi operativi posti in successione: gruppo di impregnazione (29) comprendente almeno una vasca (22); primo gruppo di asciugatura (30) comprendente un forno (31a) ad aria calda; gruppo di vaporizzazione (34); gruppo di lavaggio in acqua calda (35) comprendente almeno una vasca (22); gruppo di neutralizzazione (36) comprendente almeno una vasca (22); gruppo di lavaggio in acqua fredda (37) comprendente almeno una vasca (22); gruppo di seconda asciugatura (38) finale comprendente un forno (31b) ad aria calda; gruppo di raccolta fili (11) comprendente almeno un subbio di raccolta (39).Continuous mercerization process suitable for carrying out the mercerization treatment on a plurality of threads (11) of polyester fibers which run continuously and parallel to each other, from one (12) or more (112, 212) beams feeding, said plurality of threads (11) being subjected in succession to the following operating steps: impregnation (13) by immersion in the bathroom in at least one tank (22) containing a heated caustic soda bath; first drying (14) in oven (31a) with hot air circulation; vaporization (15) with water vapor; neutralization with hot washing, said neutralization comprising a first washing stage in hot water (16) by immersion in at least one tank (22) containing a hot water bath, a second neutralization stage (17) proper by immersion in at least one tank (22) containing an acid bath, and a third rinsing stage (18) by immersion in at least one tank (22) containing a cold water bath; second final drying (19) in oven (31b) with hot air circulation; said threads (11), as coming out of the second final drying (19), being wrapped in at least one collection beam (39). Continuous mercerization plant suitable for carrying out the mercerization treatment on a plurality of threads (11) of fibers. of polyester unfolding continuously and to each other parallel from one (12) or more (112, 212) feeding beams, said plant (20) adopting the above process (10), comprising the following operating groups placed successively: impregnation group (29) comprising at least one tank (22); first drying group (30) comprising a hot air oven (31a); vaporization group (34); hot water washing unit (35) comprising at least one tank (22); neutralization group (36) comprising at least one tank (22); washing unit in cold water (37) comprising at least one tank (22); final second drying unit (38) comprising a hot air oven (31b); wire collection unit (11) comprising at least one collection beam (39).
