Definitions

  • the invention relates to a composition for the permanent hydrophilic finish of textile fibers and textile products made thereof, such as nonwovens.
  • nonwovens For the production of nonwovens various methods are available. When spunbonding by spunbond process or melt-blow process, the filaments formed by the melt spinning process of extruded polymers are forced under high pressure through spinnerets, stretched in a hot or cold air stream and deposited into a nonwoven. The nonwoven fabric can be subsequently solidified chemically, mechanically or thermally. In the production of dry nonwovens staple fibers are used, which are first carded to form a batt and then solidified chemically, mechanically or thermally.
  • Hydrophilic nonwovens are used in particular as cover fleeces or as intermediate fleeces for hygiene articles such as baby diapers, sanitary napkins, incontinence products and similar products. Such webs have the task to forward body fluids such as urine and blood quickly to the underlying absorption layer.
  • thermoplastic polymers such as polyolefin or polyester are mostly used.
  • these polymers are hydrophobic and therefore have to be rendered hydrophilic either during fiber production and / or further processing into nonwoven fabric.
  • the hydrophilization is carried out by treating the filaments with known spin finishes, which can then be further processed into staple fibers and / or directly into nonwoven fabrics. It is also more usual to treat the nonwovens before further processing into a hygiene article with a hydrophilic finishing agent as a so-called "top coat".
  • hydrophilic spin finish or a hydrophilic finishing agent The treatment of the hydrophobic fibers, filaments or nonwovens with a hydrophilic spin finish or a hydrophilic finishing agent is intended to give as long as possible a lasting hydrophilicity over the longest possible period of use of the nonwoven.
  • the hydrophilic spin finish or the finishing agent should therefore adhere well to the hydrophobic web and not or only slightly washed out by liquids.
  • Modern nonwovens should have a permanent hydrophilicity and be wetted several times with water or body fluids such as urine.
  • compositions for hydrophilic finishing of nonwoven fabrics and fibers for sanitary applications have heretofore been sold as either nearly anhydrous oils or as dilute aqueous dispersions to achieve permanent hydrophilization of the fibers or nonwovens.
  • the commercially available compositions are then diluted on site in fiber or nonwoven production with water, applied from aqueous dilution on the fibers or nonwovens and then dried.
  • the patent DE 196 45 380 B4 discloses a composition for the permanent hydrophilization of polyolefin fibers with cationically modified siloxanes, esterquats and nonionic surfactants.
  • the commercially available compositions all contain water and / or solvents and show only a limited storage stability.
  • the invention has for its object to provide a composition for the permanent hydrophilic finish of textile fibers and fabrics such as nonwovens, which has an improved storage stability and with the stable permanent-hydrophilic finish of textile fibers and fabrics is achieved.
  • composition according to the invention can advantageously be diluted with water as required by the customer and can be diluted from the aqueous dilution onto the water be applied hydrophilic fibers or the fleece.
  • the provision as a composition with a melting point above 45 ° C ensures sufficient storage stability.
  • composition according to the invention exhibits a permanent-hydrophilic finishing of textile fibers and textile products comparable to the performance of spin finishes and finishing agents based on aqueous dispersions while retaining their respective performance properties.
  • the composition of the invention is present as granules. This allows a reduction in storage and transport costs and simplified handling at the customer. In addition, the granular composition is less sensitive to changing storage conditions.
  • composition according to the invention may also be provided as an aqueous dispersion having a solids content of at least 10% by weight, preferably at least 15% by weight. Also in this case, the storage stability compared to dilute aqueous dispersions is significantly improved.
  • the melting point of the composition is at least 55 ° C.
  • the upper limit of the melting point of the composition according to the invention is dependent on the components used in each case and the dispersibility and the desired performance properties of the composition. The inventors believe that compositions with a melting point above 120 ° C, preferably above 90 ° C, can no longer be meaningfully used as finishing agents for textile fibers and textile products.
  • the composition of the invention For the preparation of the composition of the invention predominantly components of highly viscous or solid materials are used. Nevertheless, the application properties of the nonwovens vulcanized with the composition according to the invention, such as multiple strike through, multiple run off, wetback and wash-off not adversely affected compared to the previously used aqueous dispersions. Rather, the fibers and nonwovens treated with the composition of the present invention exhibit good permanent hydrophilicity and a good rate of absorption.
  • fibers also includes “filaments”, including single filaments and multi-filaments.
  • filaments including single filaments and multi-filaments.
  • fibers and filamentaments are therefore used synonymously.
  • hydrophobic fibers, materials or surfaces are referred to, which are not spontaneously wetted with water or have a contact angle of greater than 90 °. Hydrophilic fibers, materials and surfaces are wettable spontaneously with water and aqueous liquids or show a contact angle of less than 90 °.
  • "permanently hydrophilic” means a textile product (fiber or flat fabric) treated with a finishing agent, which has the "Multiple Strike Through” test in accordance with WSP standard 70.7 (11) with penetration times of ⁇ 2 / ⁇ 3 / ⁇ 5 / ⁇ 5 / ⁇ 5 seconds.
  • the storage stability of the dispersions known from the prior art is up to about 6 months.
  • the compositions of the present invention may be stored for at least 12 months at 22 ° C and 50% relative humidity without degradation of product properties as measured by the multiple strike-through test. Even in the form of highly concentrated dispersions having a solids content of at least 10%, preferably at least 15%, the compositions of the invention remain castable under these conditions.
  • the preferred granular compositions are considered to be stable on storage if the appearance of the granules does not change after storage at 50 ° C. for 3 days.
  • textile fibers in particular synthetic fibers or filaments of polyolefins such as polyethylene and polypropylene as well as polyesters such as polyethylene terephthalate (PET) and polylactides (PLA) or bicomponent fibers of polyolefins and polyesters are used.
  • PET polyethylene terephthalate
  • PLA polylactides
  • Made from these fibers Textile products are preferably non-woven fabrics (nonwovens), in particular nonwovens.
  • the components of the composition are melted and mixed together with stirring. Thereafter, granulation or scaling is carried out from the melt, whereby various granulation techniques and scaling techniques known in the art may be used.
  • the hydrophilically modified polyalkylsiloxane of component (A) may be cationically or anionically modified, or may have a non-ionic pendant hydrophilic group.
  • the hydrophilically modified polyalkylsiloxane preferably has a viscosity at 25 ° C. of at least 3500 mPas. Particularly preferably, the viscosity of the polyalkylsiloxane at 22 ° C at least 5000 mPa s and is preferably in the range of 5 to 100 Pa s, in particular between 50 and 80 Pa s. The viscosity is measured according to DIN ISO 2555.
  • component (A) preferably comprises a cationically modified polyalkylsiloxane having at least one quaternary ammonium group.
  • the hydrophilically modified polyalkylsiloxane of component (A) comprises a nonionic alkoxylated polyalkylsiloxane having an ⁇ , ⁇ structure or comb structure, optionally end-capped with alkyl groups, acyl groups or phosphate groups.
  • Suitable high-viscosity, hydrophilically modified polyalkylsiloxanes are commercially available, for example, under the name TEGOPREN TM from Evonik Industries or as L-series silicone oil from Wacker AG.
  • the hydrophilically modified polyalkylsiloxane of component (A) imparts to the composition of the invention the ability of rapid hydrophilization with good permanence and improves the absorbency of the products treated with the composition according to the invention.
  • the proportion of component (A) in the composition of the invention is in the range of 3 to 30 wt .-%, preferably in the range of 10 to 25 wt .-%, based on the total weight of the composition. A higher proportion of the component (A) deteriorates the processing and / or granulating ability of the composition and increases the price.
  • At least the radical R 1 in the above formula (II) comprises an alkyl group or alkylene group having 12 to 24 C atoms.
  • the quaternary ammonium compound has a melting point of at least 55 ° C.
  • the selection of refractory quaternary ammonium compounds ensures good granulation ability of the composition of the invention.
  • the quaternary ammonium compound also shows good permanent hydrophilicity properties.
  • Suitable quaternary ammonium compounds are commercially available, for example under the name Dehyquart TM F 75 (BASF).

Too high proportion of the quaternary ammonium compound deteriorates the Absorption speed of fluids, which is reflected in a deteriorated value of the first breakdown value in the multiple strike-through test. Too low proportion of the quaternary ammonium compound impairs the granulation ability of the compositions.
  • the composition as component (C) may have an optionally hydroxylated fatty alcohol in an amount of 0 to 25% by weight.
  • the proportion of the fatty alcohol is in a range of 5 to 15 wt .-%, particularly preferably between 10 and 15 wt .-%, based on the total weight of the composition.
  • the fatty alcohol serves as a solvent for the components (A) and (B) and improves the homogeneity and consistency of the granules.
  • the addition of fatty alcohols can improve the shelf life of the composition.
  • too high a proportion of fatty alcohol deteriorates the hydrophilizing effect of the composition.
  • the hydrocarbon chains of the optionally hydroxylated fatty alcohol may be branched or straight chain, saturated or unsaturated. Particularly preferred are fatty alcohols having 16 to 32 carbon atoms in the hydrocarbon chain. Suitable examples are cetyl alcohol (mp 49 ° C) and stearyl alcohol (mp 59 ° C).

  • the esters may be alkoxylated or non-alkoxylated, with preferably 0 to 10, preferably 0 to 6, and more preferably 2 to 6 alkoxy groups.
  • a solid fatty acid amide having 12 to 28 C atoms in the carbon chain can be used as consistency regulator in the composition according to the invention.
  • the fatty acid amide is particularly free of Nitrosamines.
  • An example of a suitable fatty acid amide is stearic acid monoethanolamide.
