Definitions

  • warp yarns are provided with solutions, melts, dispersions or emulsions of sizing agents which impart smoothness, consistency, suppleness and strength to the yarn, so that processing on the loom is improved. After weaving, the sizing agent is removed in most cases.
  • Sizing agents based on naturally occurring polysaccharides e.g. Starch sizing is characterized by good biodegradability, but it is not or only insufficiently suitable for sizing semi-or. fully synthetic fibers. They are therefore preferably used in mixtures with the agents mentioned.
  • the invention now relates to a readily biodegradable, water-washable sizing agent, which is distinguished by excellent adhesive strength and smoothness.
  • the polysaccharide from the seeds of Cassia Occidentalis after monohydroxyalkylation and partial depolymerization, gives an excellent sizing agent for yarns made of cotton, regenerated cellulose and synthetic fibers, and mixtures thereof.
  • Dihydroxypropyl ethers of polysaccharides including Cassia occidentalis, are in principle already known from US-A-2496 670.
  • the invention relates to a sizing agent for yarns made of cotton, regenerated cellulose and synthetic fibers, and mixtures thereof, which essentially consists of a monohydroxyalkylated polysaccharide from the seeds of Cassia Occidentalis, which has a viscosity of 40-10,000 mPas (10% aqueous solution, 80 ° C, Brookfield RVT) and has a degree of substitution of 0.05 - 1.0.
  • the sizing agents according to the invention have a viscosity range of 40-10,000 mPas, preferably 200-9,000 mPas, in aqueous solution with a dry substance content of 10%.
  • the viscosity is measured at 80 ° C. on a Brookfield viscometer, model RVT, at 20 rpm.
  • the monohydroxyalkylated polysaccharides used according to the invention as sizing agents have a degree of substitution of 0.05-1.0, preferably 0.1-0.9.
  • Monohydroxyethylated and monohydroxypropylated polysaccharide is preferred, although in principle monohydroxy-C 2-4 -alkylated polysaccharide can be used.
  • the polysaccharide from Cassia Occidentalis used according to the invention is predominantly a galactomannan.
  • the sizing agents according to the invention are prepared by hydroxyalkylating polysaccharide from the endosperms of Cassia Occidentalis with an alkylene oxide or haloalkanol in a manner known per se and depolymerizing before, during or after the hydroxyalkylation in order to achieve the desired viscosity in a manner known per se.
  • the depolymerization can be carried out, for example, with hydrogen peroxide or with inorganic peroxides, or by hydrolysis or by means of enzymes.
  • the polysaccharide from endosperms of Cassia Occidentalis is first kneaded briefly with aqueous NaOH solution in a kneader mixer, then the mixture is mixed with an alkylene oxide, such as preferably ethylene oxide. or propylene oxide, added and worked well at a temperature of 40 - 80 ° C for several hours with the mixer closed.
  • an alkylene oxide such as preferably ethylene oxide. or propylene oxide
  • the depolymerization is carried out using an aqueous hydrogen peroxide solution elevated temperature, for example 50 - 90 ° C, carried out. This depolymerization can also be carried out before the hydroxyalkylation.
  • the resultant, almost homogeneous paste can then be dried on a drum dryer, for example. A cold and hot water soluble product is obtained.
  • the sizing agent according to the invention is practically salt-free and, even in its molecular structure, is not a salt, e.g. the carboxymethylates or polyacrylates.
  • salt-free sizing agents protect the weaving tableware and cause no corrosion.
  • the products according to the invention have the advantage of significantly better sizing effects compared to the set-free starch sizing.
  • the size according to the invention is readily biodegradable and can be easily removed from the waste water in a biological sewage treatment plant.
  • polyvinyl alcohol it is also readily soluble in an alkaline medium.
  • the yarns sized with this have a good surface smoothness and thus have sufficient resistance to the heavy demands of the weaving process. This applies in particular to very dense fabric qualities.
  • the sizing can be easily removed from the fabric simply by washing with water, there are additional advantages for further processing. For example, time and costly enzymatic desizing.
  • the sizing agent according to the invention is readily biodegradable.
  • the chemical oxygen requirement of such a size solution drops to less than 20% of the initial value after 5 days of incubation with activated sludge.
  • Comparisons with the commonly used water-washable sizing agents show that polyvinyl alcohol, polyacrylates and carboxymethyl cellulose are practically not subject to degradation under these conditions.
  • the excess propylene oxide is removed by vacuum and the reaction mixture is mixed with 5 parts of hydrogen peroxide (approx. 32%) in 500 parts of water and kneaded at 60-90 ° C. for about 90 minutes.
  • the paste is then homogeneous and is dried in a thin layer using a drum dryer.
  • the scale-like sizing agent is cold and hot water soluble, the 10% aqueous solution shows a viscosity of approx. 7000 - 8500 mPas at 80 ° C.
  • the sizing agent has a degree of substitution of 0.27.
  • the scale-shaped sizing agent is cold and hot water soluble, its 10% aqueous solution shows a viscosity of approx. 1000 mPas at 80 ° C.
  • the degree of substitution was determined with 0.25 (iodine-hydrogen method).
  • the scale-like sizing agent is soluble in cold and hot water, its 10% aqueous solution shows a viscosity of approx. 700 mPas at 80 ° C.
  • the degree of substitution was determined to be 0.7 (iodine-hydrogen method).
  • the scale-like sizing agent is soluble in cold and hot water. Its 10% aqueous solution shows a viscosity of approx. 800 mPas at 80 ° C. The degree of substitution was determined to be 0.3 (iodine-hydrogen method).
  • a cold and hot water-soluble powdered sizing agent After drying in vacuo, a cold and hot water-soluble powdered sizing agent is obtained.
  • the 10% aqueous solution of the sizing agent shows a viscosity of approx. 1200 mPas at 80 ° C.
  • the degree of substitution was determined using 0.25 (iodine-hydrogen method).
  • the temperature in the sizing trough was constant at 85 ° C.
  • the chain was immersed once in the liquor and squeezed twice, a squeezing effect of 115% being achieved.
  • the warp yarn was processed on Sulzer weaving machines, the weaving efficiency being 98.0%. 0.005 warp thread breaks were calculated for 1000 warp and 10,000 weft threads.
