Definitions

  • Fibrous fiber sizing agent and use thereof
  • the present invention relates to a filament fiber sizing agent and the use thereof.
  • the so-called sizing of textile fibers is analogous to the other usage a smoothing process, although the smoothing is not the only and not the essential aspect. Other aspects are the bonding and solidification of the fibers.
  • the yarns which are used as warp yarn during weaving are treated. Since the yarns are originally open-structured, they can not withstand the varied and sometimes intense strains of weaving. They would roughen, especially due to abrasion, forming fiber suspensions that make weaving impossible. Yarn damages of this and other kind are therefore absolutely to be avoided. For this reason, the yarns are protected. This protection is achieved by the application of a curable adhesive, which, in simplified terms, forms a protective film around the yarn.
  • the adhesive is called "sizing.”
  • the sizing is dissolved in water and applied to the warp yarn as a "sizing liquor". After the weaving process, the sizing is in most cases removed from the fabric, i. washed out as it can hinder the subsequent refining processes.
  • the sizing agent should form a film which also has a certain elasticity.
  • the sizing agent must also have good adhesion to those fibers making up the yarn.
  • the viscosity of the sizing liquor must not be too high or too low at the concentration required for technological reasons.
  • the sizing should be soluble in water or solubilized by boiling.
  • the sizing should be shear stable.
  • the sizing should be as easy as possible washable or removable.
  • the sizing liquor must not be retrograded. ren, do not form skin or tend to foam.
  • the sizing agent should be compatible with other products available on the market and should also be compatible with the necessary auxiliaries such as fats, wetting agents, etc. Overall, it is advantageous if the sizing agent as such is environmentally friendly.
  • Filament fibers are continuous filaments which are obtained by spinning out a spinning composition consisting mostly of synthetic or even natural polymers. All filaments have in common that in the spinning process, the starting material, which is present as granules, is liquefied either by melting or dissolving. Subsequently, the spinning mass is pumped through nozzles. After solidification of the fibrils, which can be effected by different methods, the filament yarns are collected on a roll.
  • Spun fibers are made by warping and twisting finite length fibers of mostly natural origin, such as cotton.
  • filaments have a smoother surface, while spun yarns are often very open-structured. Therefore, depending on the fiber type different sizing agents are used.
  • starch-based sizing agents are used in the spun-fiber sector, whereas in the filament-fiber sector predominantly synthetic products such as polyvinyl alcohol, acrylates or polyesters are used.
  • a Filamenmaschineschlichtesch Specific requirements for a Filamenmaschineschlichtesch include a low viscosity, that is a viscosity of less than 100 mPa.s (Brookfield viscosity, measured for a 10% solution in water at 5O 0 C).
  • the filament sizing should show good adhesion to filament fibers, such as polyester and polyamide, but also on mineral filament fibers. Furthermore, high stability is achieved even at low temperatures. wishes. Mineral fiber filaments also require a low ash content.
  • the filament sizing agent should show a very good film formation on smooth surfaces and preferably allow washing out exclusively with water.
  • polyesters for example Dacron® from DuPont, Trevira® from Hoechst and Diolen® from Akzo
  • polyamide for example Perlon® from Bayer / Akzo, Nylon® from DuPont / Akzo and Kevlar from DuPont
  • polyacrylonitrile for example, Dolan ® from Hoechst, Dralon ® from Bayer and Orion ® from DuPont.
  • the basic chemical component of all synthetic fibers is derived from petroleum.
  • the individual molecules are built up by polymerization, polycondensation or polyaddition to different polymers.
  • Man-made fibers synthetic fibers have less structure than natural fibers and therefore a smoother surface.
  • filament fibers Another important class of filament fibers consists of minerals, such as SiO 2 (quartz). These glass lattices are characterized by particular strength and are used in various industries, such as the electronics, automotive and construction industries.
  • Synthetic sizing agents are mainly derived from petroleum.
  • existing starch based sizing products for use with filament fibers have not shown the required affinity for the filaments, the affinity being understood to mean the adhesion, adhesion, or adhesion of the sizing agent to the fiber.
  • starch-based sizing products unlike the synthetic products, would consist of a renewable raw material that is available and biodegradable in large quantities.
  • the first object is achieved by a filament fiber sizing agent comprising at least 50% by weight of at least one legume starch having an amylose content of at least 60% by weight.
  • the filament fiber is selected from synthetic, natural or mineral fibers.
  • the filament fiber is particularly preferably selected from polyester, polyamide, polyacrylonitrile and glass.
  • the legume starch is selected from pea, bean, lentil, soybean, peanut, lupine and mixtures thereof.
  • the legume starch is chemically and / or physically modified.
  • the legume starch is esterified.
  • the legume starch is acetylated, preferably with an acetyl content of 1 to 5%.
  • the acetyl content here refers to the proportion of all possible acetylatable functional groups of the starch.
  • the legume starch is extruded. During extrusion, the starch is converted under the influence of high temperatures (for example about 130 ° C.), pressure and shear into a product which is soluble in cold water and very stable and low in viscosity. Extrusion is well known in the art.
  • the legume starch preferably has an amylose content of from 60 to 90% by weight, preferably from 65 to 90% by weight, particularly preferably from 70 to 80% by weight.
  • the sizing agent may be mixed with at least one other natural and / or synthetic sizing agent.
  • the mixture has a starch content of at least 50 wt .-%.
  • the legume starch may be genetically modified.
  • the sizing agent according to the invention can therefore be used for application to filament fibers.
  • the sizing agent according to the invention is first applied to the fiber and, after the weaving of the fiber, removed from the fabric thus produced, preferably by washing only with water.
  • an excellent filament fiber sizing agent can be provided if it comprises at least 50% by weight of at least one legume starch having an amylose content of at least 60% by weight.
  • a filamentary fiber sizing agent comparable values can be obtained in terms of affinity, bond strength and elongation as for synthetically prepared filamentary fiber sizing agents, as will be understood from the example section below.
  • the basic building block of starch consists of alpha-D-glucose. Linkage of the glucose units in the 1,4-position forms the straight-chain molecule amylose, while in the presence of a simultaneous 1,6-linkage, the amylopectin is formed.
  • Usual strengths therefore consist of two different molecules. It has long been known that these two molecules, amylose and amylopectin, have different properties.
  • An essential aspect of the invention is therefore also the use of a legume starch having an amylose content of at least 60% by weight in the production of a fiber-type fiber sizing agent which then comprises at least 50% by weight of this leguminous starch.
  • Figure 1 shows a graph of the Brookfield viscosity of a fiber sizing agent according to the invention versus concentration.
  • a sizing agent is usually defined in combination with the particular substrate, ie the substrate to which the sizing agent is to be applied. Therefore, in order to be able to compare sizing directly with each other, all other parameters must be identical, which is hardly feasible in practice. However, in order to still be able to carry out comparative measurements, for example with regard to the bond strength, the rotor-ring method was used in the following, which is described in "New Investigations on the Adhesion of Sizing Agents", Textiltechnik Int., December 1989.
  • the rotor assembly and sizing liquor have a temperature of 85 ° C., which corresponds to the practical temperature, and the fiber ribbon thus produced is subjected to a tensile test, in which tensile strength and elongation are measured If several tests are carried out with different concentrations, a linear curve is created Value selected at 1% trim. The results of the rotor-ring method are fully compatible with the practice.
  • pea starch ester thus prepared corresponds to the marker pea starch ester F8125 shown in Table 1 below.
  • Table 1 shows a range of starch products with different levels of amylose and amylopectin and the values for bond strength and elongation on polyester fibers determined by the rotor-ring method.
  • Table 2 shows bond values and elongation values of synthetic sizing products on polyester fibers.
  • Table 3 shows a comparison of a erfmdungsbeC putuvl-teffens, the pea starch ester F 8125, with a Polyacrylklareschlichtestoff in terms of adhesion and elongation on polyamide fibers.
  • Table 3 Adhesion and elongation values on polyamide fibers PA 6.6
  • the pea starch ester F 8125 a pea starch ester with a high amylose content, significantly increases the bond strength to polyester and polyamide, so that in some cases the values of the synthetic products are achieved.
  • the pea starch ester shows the advantages described above.
  • the viscosity of the pea starch ester F8125 shows excellent values, as shown for example in FIG. 1, after which a viscosity of less than 100 mPa.s is obtained in a 10% solution of the ester in water at 50 ° C.
