Description
La présente invention concerne un procédé amélioré de désencollage et de blanchiment des tissus en une seule opération dans un bain à base de peroxyde d'hydrogène.The present invention relates to an improved process for desizing and bleaching fabrics in a single operation in a bath based on hydrogen peroxide.
La demanderesse a mis au point un tel procédé faisant l'objet de la demande de brevet EP-A 0055664.The applicant has developed such a process which is the subject of patent application EP-A 0055664.
Le procédé de la demande de brevet EP-A 0 055 664 utilise un bain comprenant du peroxyde d'hydrogène, de l'hydroxyde de sodium, un agent séquestrant, une amylase, un agent tensio-actif et éventuellement un agent stabilisant tel le silicate de sodium.The process of patent application EP-A 0 055 664 uses a bath comprising hydrogen peroxide, sodium hydroxide, a sequestering agent, an amylase, a surfactant and optionally a stabilizing agent such as silicate sodium.
La mise en oeuvre industrielle de ce procédé se heurte à certaines difficultés:
- - d'une part les résultats obtenus dépendent du pH fixé au départ. En effet à un pH très alcalin le blanchiment est excellent mais le désencollage est en général insuffisant, inversement à un pH peu alcalin le désencollage est bon mais le blanchiment est insuffisant.
- - d'autre part le niveau des résultats est étroitement lié à la nature du tissu soumis au traitement de désencollage - blanchiment, la dégradation enzymatique des amidons générant des produits acides qui font évoluer le pH au cours de la réaction.
- - on the one hand, the results obtained depend on the pH set at the start. In fact, at a very alkaline pH, the bleaching is excellent but the desizing is generally insufficient, conversely at a slightly alkaline pH, the desizing is good but the bleaching is insufficient.
- - on the other hand the level of the results is closely linked to the nature of the tissue subjected to the desizing treatment - bleaching, the enzymatic degradation of the starches generating acid products which cause the pH to change during the reaction.
Selon la quantité et la nature des amidons utilisés pour l'encollage du tissu le pH du bain de désencollage - blanchiment est plus ou moins modifié au cours du traitement, ce qui conduit à des écarts importants au niveau des résultats de blanchiment et de désencoliage.Depending on the quantity and nature of the starches used for sizing the fabric, the pH of the desizing-bleaching bath is more or less modified during the treatment, which leads to significant differences in the bleaching and desizing results.
Ces observations ont conduit la demanderesse à rechercher un tampon susceptible de fixer le pH du bain de désencollage - blanchiment afin de disposer d'un procédé de désencollage - blanchiment simultané permettant d'obtenir à la fois un désencollage et un blanchiment optimum tout en respectant le degré de polymérisation de la fibre.These observations have led the applicant to seek a buffer capable of fixing the pH of the desizing - bleaching bath in order to have a desizing process - simultaneous bleaching making it possible to obtain both optimum desizing and whitening while respecting the degree of polymerization of the fiber.
La présente invention répond à un tel objet et fournit un procédé amélioré de désencollage - blanchiment simultané des tissus dans un bain comprenant du peroxyde d'hydrogène, un agent séquestrant, une amylase et un agent tensio-actif caractérisé par le fait que l'on ajoute audit bain un tampon constitué par du tétraborate de sodium décahydraté en quantité telle que le pH du bain soit égal à 9,8.The present invention fulfills such an object and provides an improved process for desizing - simultaneous bleaching of tissues in a bath comprising hydrogen peroxide, a sequestering agent, an amylase and a surfactant, characterized in that add to said bath a buffer consisting of sodium tetraborate decahydrate in an amount such that the pH of the bath is equal to 9.8.
Au cours de ses recherches, la demanderesse a testé de nombreux tampons et a constaté avec surprise que pour aucun tampon à l'exception du tétraborate de sodium décahydraté, on obtenait à la fois un bon désencollage et un bon blanchiment.During its research, the plaintiff tested numerous buffers and found with surprise that for no buffer except for sodium tetraborate decahydrate, both good desizing and good bleaching were obtained.
Un bain de désencollage - blanchiment utilisable selon l'invention peut par exemple comporter:
L'adoption du procédé de désencollage - blanchiment simultané de la présente invention permet des économies importantes en eau, vapeur, main d'oeuvre et investissements et conduit à des résultats de désencollage - blanchiment supérieurs à ceux que l'on obtient sans tampon ou en utilisant un autre tampon permettant de fixer le pH du bain à une valeur équivalente.The adoption of the desizing - simultaneous bleaching process of the present invention allows significant savings in water, steam, labor and investment and leads to desizing - bleaching results greater than those obtained without buffer or in using another buffer allowing the pH of the bath to be fixed at an equivalent value.
En outre l'utilisation du tétraborate de sodium décahydraté comme tampon évite de travailler en milieu fortement alcalin et protège ainsi le tissu traité contre la formation de «cassures» au cours d'un dépôt en plis.In addition, the use of sodium tetraborate decahydrate as a buffer avoids working in a strongly alkaline medium and thus protects the treated fabric against the formation of "breaks" during deposition in folds.
L'invention sera à présent décrite plus en détails dans les exemples non limitatifs suivants.The invention will now be described in more detail in the following nonlimiting examples.
Les essais de désencollage - blanchiment décrits ont été réalisés selon la technique suivante:
- 1. Imprégnation du tissu écru dans le bain de désencollage - blanchiment; exprimage pour ne laisser dans le tissu que la quantité de bain nécessaire à la réaction. Cette quantité a été fixée à 100% du poids de tissu sec.
- 2. Vaporisage pour porter le tissu à la température de réaction souhaitée 90-95°C.
- 3. Dépôt par enroulage ou en plis pendant une heure à température.
- 1. Impregnation of the unbleached fabric in the desizing bath - bleaching; expressing so as to leave in the tissue only the quantity of bath necessary for the reaction. This amount was set at 100% of the weight of dry fabric.
- 2. Spraying to bring the fabric to the desired reaction temperature 90-95 ° C.
- 3. Deposit by winding or in folds for one hour at temperature.
Le traitement est suivi d'un lavage à 90-95°C, d'un lavage à 60°C et d'un lavage à froid.The treatment is followed by washing at 90-95 ° C, washing at 60 ° C and cold washing.
Le bain de base de désencollage - blanchiment utilisé dans les exemples ci-après est le suivant:
Les exemples 1 à 5 ci-dessous ont été effectués avec une toile de coton 100% de 160 g/m2:
- taux d'amylacés 9,20%
- réflectance ELREPHO (La mesure du degré de blanc est effectuée à l'aide du reflectomèfre ELREPHO de la Société KARL ZEISS de la Républi- que Démocratique d'Allemagne) 56°
- indice de polymérisation 1 940
- starch rate 9.20%
- Elrepho Reflectance (Measurement of brightness is performed using the Elrepho reflectomèfre Company KARL ZEISS of the Re p ubli- that Democratic Germany) 56 °
- polymerization index 1,940

L'exemple 5 illustre un procédé selon la présente invention.Example 5 illustrates a method according to the present invention.
Les résultats sont indiqués dans le Tableau 1 ci-après.
Seul l'emploi du métaborate de sodium (Ex. 3) donne un degré de blanc supérieur à celui obtenu avec le tétraborate de sodium décahydraté (Ex. 5 selon l'invention), mais le taux d'amidon résiduel obtenu dans l'Exemple 3 est trop élevé (le taux d'amidon résiduel de l'Exemple 3 est de 0,61 alors qu'il n'est que de 0,22 dans l'Exemple 5 selon l'invention).Only the use of sodium metaborate (Ex. 3) gives a higher degree of white than that obtained with sodium tetraborate decahydrate (Ex. 5 according to the invention), but the level of residual starch obtained in Example 3 is too high (the residual starch level of Example 3 is 0.61 while it is only 0.22 in Example 5 according to the invention).
En outre l'hydrophilie de l'Exemple 5 est 10 fois plus faible que celle de l'Exemple 3. On notera également que le degré de polymérisation (DP - 1 620) obtenu dans l'Exemple 5 selon l'invention montre que la fibre n'est pas dégradée au cours de l'opération de désencollage - blanchiment.In addition, the hydrophilicity of Example 5 is 10 times lower than that of Example 3. It will also be noted that the degree of polymerization (DP - 1,620) obtained in Example 5 according to the invention shows that the fiber is not degraded during the desizing - bleaching operation.
