Description

The present invention relates to compositions comprising at least one cationic polyelectrolyte, at least one anionic compound and at least one nonionic surfactant and their use for finishing fibers and textiles.

Ever-increasing demands are placed on textiles today. Depending on the field of application, textiles are to be used e.g. hydrophobic, hydrophilic, flameproof, antistatic, crease resistant, oil repellent, weatherproof, etc. These requirements can no longer be satisfied by the mere selection of a suitable fiber material. In the art, therefore, the surface of the fibers and / or textiles is increasingly being chemically modified, i. equipped to tailor the property profile of the textile according to the area of application.

• geringere Knitterneigung
• hohe Reiß- und Scheuerfestigkeit
• hohe Variabilität der Eigenschaften durch Wahl der Monomere
• geringes Gewicht
• geringe Herstellungskosten

Textiles are usually made from fibers, whereby a distinction is made between natural fibers, ie fibers which are obtained without chemical modification from vegetable fibers, eg cotton, or animal fibers, eg wool or silk, and synthetic fibers. Unlike natural fibers, most synthetic fibers have significant advantages:

• lower crease tendency
• high tear and abrasion resistance
• high variability of the properties by choice of monomers
• low weight
• low production costs

Therefore, more synthetic fibers than natural fibers are currently being processed into textiles worldwide. However, despite the advantages, synthetic fibers also have disadvantages. Thus, synthetic fibers are increasingly electrostatically charged to natural fibers. Also, the synthetic fibers hardly absorb moisture, which has a negative effect on the wearing comfort. Textiles made of synthetic fibers can therefore not or only to a limited extent in certain areas, e.g. be used by combining with natural fibers.

In order to impart antistatic and / or hydrophilizing properties to synthetic fibers, so-called finishing agents can be used which are applied to the surface of the fibers or textiles. However, it is usually difficult to machine-fix the finishing agents to synthetic fibers, as synthetic fibers have few or no functional groups which can be used in the finish, e.g. can permanently bind to the fiber or textile through covalent, ionic or v. dwarf interactions. To solve the problem, in most cases finishing agents are used which are self-crosslinking or can be crosslinked by another component. While such finishing agents usually have higher washing permanence, the textile feel of such finished textiles is unsatisfactory. In addition, the crosslinking reaction is usually carried out at higher temperatures, e.g. at 150 ° C, takes place. Such reaction conditions are not suitable for all fibers and can lead to undesirable yellowing, chemical degradation reactions and changes in shape of fiber and / or textile. Also, for health reasons, crosslinkable finishing agents are objectionable because the functional groups of the crosslinking agents, e.g. Epoxy, chloro hydroxyl or (blocked) isocyanate groups, which are suspected of being hazardous or even toxic. After all, the high energy consumption for the equipment is ecologically questionable.

Alternatively, equipment with complexes of cationic and anionic preparations is proposed to achieve appropriate washing permanence on a fiber or textile. This is usually a two-step process carried out in which cationic and anionic components are applied sequentially.

In EP 0 603 987 A1 describes a two-stage process in which a layer of cations and anions is successively applied to a substrate. The best washing permanence is achieved at a stoichiometric ratio between anions and cations, under which circumstances the hydrophilicity is insufficient. Although the hydrophilicity can be improved by varying the charge ratio between anions and cations, the wash permanence is adversely affected to the same extent. Acceptable hydrophilic properties with acceptable wash permanence are not achieved by the systems described.

In WO 2006/015080 A1 Substrates are alternately cationic and anionic equipped. In order to avoid deposits in the individual baths, one washing step takes place between the steps. Disadvantage of this method is that the polymers do not grow quantitatively, so that form precipitations in the liquor, which deposit on the fibers or textiles and thereby cause stains. The washing step also involves a great deal of extra work and product loss.

In US 6,060,410 B For example, a solution of a highly substoichiometric ratio of cationic and anionic molecules is applied to a substrate. The still free ionic groups are mixed in a second bath with an oppositely ionic hydrophobing component.

Also in US 5,208,111 B and US 2004/0185284 A1 Two-step processes for the formation of complexes are proposed.

The described two-stage processes are associated with a high production cost, at the same time it is difficult to ensure process stability, since the formation of insoluble complexes in the fleet the risk of unwanted deposits on fiber or textile.

Water-insoluble cation-anion complexes can also be used as solids. For this purpose, the complexes are usually precipitated in aqueous systems as ion pairs and then separated, dried and / or granulated. The products can be used in plastic moldings or other non-aqueous formulations. For aqueous media equipment, these dried, water-insoluble complexes are not suitable because they are not finely dispersed to avoid deposits and stains.

US 6,596,678 B2 describes a powdered detergent composition with a polyelectrolyte complex of cationic and anionic polymers. The polyelectrolyte complex is present in the wash liquor as a particle which deposits on the textiles to be cleaned and protects them during the washing process. After rinsing, the complex is washed out again.

In WO 2011/131728 A1 a water-precipitated anion-cation complex is dried after filtration and used as an additive in plastic moldings.

The above-described anion-cation complexes are all not suitable for finishing textiles, since homogeneous application to the fiber or textile is not possible or even can cause stains on the textile.

US 3,622,378 B describes mixtures of anionic and cationic surfactants and an amphoteric surfactant. The complexes precipitate as the mixture is diluted. Moreover, the treated fibers and textiles do not have the desired wash permanence.

In DE 19 852 584 A1 and US 6,060,410 B describes aqueous dispersions of cation-anion complexes. The dispersions are mechanically homogenized, for example by ultrasound. However, the fleet is only metastable and has a strong tendency to agglomerate. Thus, the fleet is limited suitable for use as equipment, also because there is a risk that it comes to deposits and stains on the textile to be equipped.

EP 0 603 987 B1 relates to a permanent hydrophilic-cationic surface coating. The surface to be coated is dipped in an aqueous solution of a cationic surfactant and / or polymer. To form the ion complex, an anionic surfactant and / or polymer is applied to the surface. Alternatively, a dispersion of the anion-cation complex is proposed for the coating of filters. For the coating of fibers or textiles, the ion complex described is not suitable, since it is not possible to produce sufficiently stable liquors.

• aufwändige Mehrstufenprozesse bei der Applikation
• Griffverhärtung
• thermische Vergilbung
• Verwendung physiologisch bedenklicher Ausgangsprodukte
• mangelnde Waschpermanenz
• Gefahr von Fleckenbildung durch unkontrollierte Ablagerungen

In summary, the prior art finishing agents have the following disadvantages:

• complex multi-step processes in the application
• handle hardening
• thermal yellowing
• Use of physiologically questionable starting materials
• lack of washing permanence
• Danger of staining due to uncontrolled deposits

Also, it has not yet been possible to provide an aqueous product with which a textile or a fiber permanently antistatic and hydrophilic properties can be imparted. The object underlying the invention is therefore to overcome the disadvantages of the prior art.

The composition according to the invention is preferably applied to the textiles in liquid form. The application is preferably carried out at room temperature. The composition according to the invention can be applied in a variety of ways known to the person skilled in the art for finishing on the substrate, for example the textile, the fiber or the (artificial) leather. Suitable methods are, for example, spraying, dipping, soaking, brushing or sponge application. Furthermore, the composition according to the invention can be applied by means of forced application or exhaustion. In the case of forced application, a liquor is usually provided in the desired concentration and applied by means of a forced application of aqueous medium to the pad with liquor pick-ups of 40-100%.

Preferably, the desired properties do not deteriorate after 10-20 or 5-10 washes in household washing machines or by no more than 20%.

Surprisingly, the wash-permanent equipment could be achieved not only in natural fibers but also in particular in synthetic fibers such as PE, PA, PAN and PP, which are usually difficult to equip and hardly washable be equipped due to lack of functional groups. The compositions of the invention can be applied in a one-step process at room temperature or at ambient temperature. In addition, the composition of the present invention is stable in a broad concentration range. " Stable " in the sense of the invention means that no sediment is formed. In the case of the concentrate, sediment formation is preferably observed after 3 months, more preferably after 6 months, even more preferably after 12 months, at 4 ° C, at 25-30 ° C or at 40 ° C. In the case of a liquor formulation, the composition preferably remains stable for up to 1.5-2 hours, more preferably up to 4 hours, even more preferably up to 8 hours at 4 ° C, 25-30 ° C or 40 ° C, ie no sediment forms during this period. This property of the composition causes that the fibers and textiles can be equipped homogeneously and that no sediments or deposits form on the materials to be finished.

The invention will now be described by way of example. This example is not intended to be limiting.
