Definitions

  • the invention relates to a sizing agent consisting of a mixture of hydroxyalkyl guar galactomannan and hydroxyalkyl cassia galactomannan, which is readily biodegradable and can be washed out with water, and which is distinguished by excellent adhesive strength and suppleness.
  • sizing agents are used in the weaving process to increase the strength of the warp during weaving.
  • the warp thread is partly covered, partly penetrated by the sizing agent, which on the one hand gives the warp thread sufficient strength and on the other hand also protrudes small fibers.
  • Cotton and rayon wool are mainly treated with sizes based on natural materials, in the case of mixed spun fabrics and synthetic yarns, the majority of sizes are sized with semi-synthetic or fully synthetic products, possibly also in combination with the natural products mentioned.
  • acyl-substituted starches carboxymethyl cellulose, polyvinyl alcohol and polyacrylates are used here. From the point of view of easy removability from the fabric, these products are used with advantage, in particular for the sizing of synthetic fibers. Almost without exception, however, these semi-synthetic or fully synthetic sizing agents show only very poor biodegradability, which manifests itself in a low biological oxygen requirement, but in a correspondingly high chemical oxygen requirement.
  • Sizing agents based on naturally occurring polysaccharides are characterized by good biodegradability, but they are not suitable or insufficient for sizing semi-synthetic or fully synthetic fibers. They are therefore preferably used in mixtures with the synthetic agents mentioned.
  • Protein sizing is only used to a limited extent since it is sometimes difficult to remove again.
  • the world protein market does not allow the technical use of such products from an economic point of view.
  • Sizing agents for yarns made of cotton, regenerated cellulose and synthetic fibers consisting of a hydroxyalkylated polysaccharide from the seeds of Cassia Occidentalis are disclosed in DE-A-30 16 561.
  • Dihydroxypropyl ethers of polygalactomannans are described in US-A-2,496,670, carboxyalkyl ethers of polygalactomannans are disclosed in US-A-2,477,544.
  • the Cyamopsis tetragonoloba ether is mainly used as a thickener in textile printing, mining and drilling.
  • a synergistic mixture of a) cassia galactomannan and b) carrageenan, agar and / or xanthan, which is useful as a gelling and thickening agent, is disclosed in DE-A-33 35 593.
  • DE-A-33 47 469 describes carboxyalkyl ethers and hydroxyalkyl ethers of Cassia tora polygalactomannans, which can optionally be used in combination with other polysaccharide derivatives as thickeners.
  • hydroxyalkylated cassia derivatives previously disclosed by the applicant are generally very effective when used as sizing agents because of their excellent properties, such as high adhesive strength and excellent film formation.
  • the pronounced film formation does not always have an advantageous effect. Due to the rapid formation of the film, disadvantages can also be noticeable with certain yarn qualities in that there is predominantly superficial adhesion to the warp yarn. This then leads to increased abrasion and dust formation and thus to an increased number of thread breaks.
  • warp yarns sized with hydroxyalkylated guar are easier to wash out than the warp yarns sized with hydroxyalkylated cassia.
  • the object of the present invention is to obtain the advantages of the hydroxyalkylated cassia and the hydroxyalkylated guar without having to accept their respective disadvantages.
  • the combination sizes according to the invention are readily biodegradable and are distinguished in use by excellent adhesive strength, film formation, very good film elasticity, high resistance to mechanical abrasion, reduced dust formation both in the sizing and in the weaving mill, and because of the very easy water washability economic advantages in tissue pretreatment.
  • the invention thus relates to a sizing agent consisting of a mixture of depolymerized hydroxyalkyl guar galactomannan and depolymerized hydroxyalkyl cassia galactomannan.
  • Suitable alkyl groups are those with 1-4 carbon atoms, the respective hydroxypropyl derivative is preferably used.
  • the mixture generally contains 10-90, preferably 30-70% by weight of the guar component and 90-10, preferably 70-30% by weight of the cassia component.
  • the mixture of the two components is used in aqueous solution and should be adjusted so that a 10% aqueous solution has a viscosity of 20-10,000 mPas, preferably 150-6,000 mPas (measured on the Brookfield RVT / 20 rpm at 80 ° C).
  • the guar derivative used and the cassia derivative used generally have a degree of substitution of 0.01-3.0 and, in 10% strength aqueous solution (measured at 80 ° C. on the Brookfield RVT / 20 rpm), each have a viscosity in Range of 100-10,000 mPas.
  • the Cassia derivative used is preferably derived from Cassia tora synonym obtusifolia.
  • the combination of hydroxyalkylated guar and hydroxyalkylated cassia according to the invention can be prepared by various methods. On the one hand, there is the mixture of the two individual components, which is produced by known processes can be possible. On the other hand, the hydroxyalkylation of the polysaccharides from the endosperms of guar and from the endosperms of cassia can be carried out in the desired weight ratio in a one-pot process.
  • the sizing agent according to the invention is produced, for example, by etherifying the polysaccharide mixture from the endosperms of guar and cassia with an alkylene oxide in a manner known per se and depolymerizing in a manner known per se before or after the hydroxyalkylation in order to achieve the desired viscosity.
  • Both the synergistic combination according to the invention and the mixture with carboxymethylated and / or depolymerized guar can be used in combination with PVA, polyacrylates, CMC, starch, starch ester, starch ether and dextrins as sizing agents.
  • the weight ratio of the components can vary widely.
  • Propoxylated, depolymerized cassia-tora-galactomannan produced by a known method.
  • the powdery product has a degree of substitution of 0.28 and, in 10% strength aqueous solution at 80 ° C., gives a viscosity of 450 mPas (Brookfield RVT, 20 rpm, spindle 2).
  • Propoxylated, depolymerized guar galactomannan prepared by a known method.
  • the powdery product has a degree of substitution of 0.29 and, in 10% aqueous solution at 80 ° C., gives a viscosity of 420 mPas (Brookfield RVT, 20 rpm, spindle 2).
  • Sizing agents composed of a combination of 50 parts of guargalactomannan which is depolymerized and etherified in a known manner with ethylene oxide and 50 parts of cassia galactomannan which is etherified in a known manner with ethylene oxide.
  • the degree of substitution of the two components is 0.24.
  • 10% aqueous solution at 80 ° C the powdery product gives a viscosity of 730 mPas (Brookfield RVT, 20 rpm, spindle 2).
  • a drum sizing machine with 9 drying cylinders and 2 sizing troughs was available for the practical application of the sizing agents.
  • the warp material was immersed twice and squeezed twice.
  • the liquor temperature in the size troughs was 85 ° C.
  • the liquor was prepared in a turbo cooker.
  • the warp yarn could be finished on the sizing machine with no problems with all recipe settings - apart from different dust in the dry section.
  • the chains were then woven on the same weaving machines under the same conditions.
  • the warp threads of the respective chain were subjected to application / analytical comparative laboratory tests.
  • test data found are listed in the following table:
  • a warp material Nm 68/1, raw white cotton, with 5364 threads and the fabric setting 33 / 31-68 / 76 was available, which was sized in comparative sizes with the recipes mentioned below.
  • the warps were woven under the same conditions on the same types of weaving machines.
  • the determined test data which are listed below, provide information about the running behavior of the chains in the weaving mill and the washout behavior of the size in the pretreatment of goods.
  • the chain sized with formulation 11 also shows only a small number of thread breaks, but the washability of the size is approximately 20% less.
  • the poorer washability had an effect in the tests in such a way that the fabric - sized with formulation 11 - had to pass through the washing unit twice in order to adequately remove the size.
  • the fabrics sized with the sizing agents according to the invention could be washed out perfectly in only one washing passage at a lower washing temperature.
