L?AMMONIACA LIQUIDA ? UNA SOSTANZA DI FONDAMENTALE IMPORTANZA NEL SETTORE DEL FINISSAGGIO DELLE FIBRE CELLULOSICHE IN QUANTO PERMETTE DI IMPARTIRE AI TESSUTI DETERMINATE CARATTERISTICHE MECCANICHE (AUMENTO DELLA STABILIT? DIMENSIONALE, DELLO ?SCATTO? DEL TESSUTO E DELLA SUA MORBIDEZZA) E CHIMICO-FISICHE (MAGGIORE AFFINIT? TINTORIALE) ALTRIMENTI NON RAGGIUNGIBILI CON ALTRI PRODOTTI O PROCESSI. A LIVELLO MOLECOLARE, L?AMMONIACA ? IN GRADO DI FORMARE UN ADDOTTO CON LA CELLULOSA, LA CUI STRUTTURA CRISTALLINA VIENE MODIFICATA CON LA RIMOZIONE DEL SOLVENTE, PASSANDO DALLA FORMA CELL I A FORME PI? RICCHE IN ZONE AMORFE: CELL III O CELL I MODIFICATA A SECONDA DEL METODO DI RIMOZIONE. QUESTA DIFFERENZA DI NUOVA STRUTTURA CRISTALLINA SI RITROVA QUINDI SULLE CARATTERISTICHE FINALI IMPARTITE AL TESSUTO PERMETTENDO UN RIGONFIAMENTO DELLE FIBRE E AUMENTANDO STABILIT? DIMENSIONALE, BRILLANTEZZA DEI COLORI, UTILIZZABILIT? IMMEDIATA (NON-STIRO, WASH AND WEAR), GUALCIBILIT? RIDOTTISSIMA SU TESSUTI IN CO (Italian)

L LIQUID AMMONIA? A SUBSTANCE OF FUNDAMENTAL IMPORTANCE IN THE SECTOR OF THE FINISHING OF CELLULOSIC FIBRES, AS IT ALLOWS TISSUES TO BE GIVEN SPECIFIC MECHANICAL CHARACTERISTICS (INCREASE OF THE ESTABLISHMENT? SIZE, STEP? THE FABRIC AND TENDERNESS) AND CHEMICO-PHYSICAL PROPERTIES (GREATER AFFINIT? DYES THAT WOULD OTHERWISE NOT BE REACHED WITH OTHER PRODUCTS OR PROCESSES. AT MOLECULAR LEVEL, AMMONIA? CAN IT MAKE A CLAIM WITH CELLULOSE, THE CRYSTALLINE STRUCTURE OF WHICH IS ALTERED BY THE REMOVAL OF THE SOLVENT, FROM THE FORM CELL I TO PI? RICH IN AMORPHOUS AREAS: GSM III OR CELL I MODIFIED ACCORDING TO THE METHOD OF REMOVAL. THEREFORE, THIS DIFFERENCE IN NEW CRYSTALLINE STRUCTURE CAN BE FOUND ON THE FINAL CHARACTERISTICS GIVEN TO THE TISSUE BY ALLOWING FIBRES TO SWELL AND TO INCREASE IT? DIMENSIONAL, BRIGHTNESS OF THE COLOURS, LIT? IMMEDIATE (NONSTRORO, WASH AND WEAR), GUALCIBILILIT? VERY LOW ON TISSUE IN CO (English)

DE L’AMMONIAC LIQUIDE? UNE SUBSTANCE D’IMPORTANCE FONDAMENTALE DANS LE DOMAINE DE LA FINITION DES FIBRES CELLULOSIQUES CAR ELLE PERMET DE TRANSMETTRE CERTAINES CARACTÉRISTIQUES MÉCANIQUES AUX TISSUS (AUGMENTATION DE LA STABILITÉ? DIMENSIONNEL, DU?SCATTO? DU TISSU ET DE SA DOUCEUR) ET CHIMIQUE-PHYSIQUE (PLUS D’AFFINITÉ? TEINTURE) AUTREMENT INATTEIGNABLE PAR D’AUTRES PRODUITS OU PROCÉDÉS. AU NIVEAU MOLÉCULAIRE, L’AMMONIAC? CAPABLE DE FORMER UN ADDUIT AVEC DE LA CELLULOSE, DONT LA STRUCTURE CRISTALLINE EST MODIFIÉE PAR L’ÉLIMINATION DU SOLVANT, DE LA FORME CELLULAIRE AUX FORMES PI? RICHE EN ZONES AMORPHES: CELLULE III OU CELLULE I MODIFIÉE EN FONCTION DE LA MÉTHODE D’ENLÈVEMENT. CETTE DIFFÉRENCE DE NOUVELLE STRUCTURE CRISTALLINE SE RETROUVE ALORS SUR LES CARACTÉRISTIQUES FINALES TRANSMISES AU TISSU PERMETTANT UN GONFLEMENT DES FIBRES ET UNE STABILITÉ CROISSANTE? DIMENSIONNEL, BRILLANCE DES COULEURS, FACILITÉ D’UTILISATION? IMMÉDIAT (NON-STIRO, LAVAGE ET USURE), GUALCIBILIT? TRÈS FAIBLE EN CO-TISSUS (French)
