Definitions
- the invention relates to a cellulose molded body and a method for its production
- cellulose occurs in five crystalline modifications, namely 1.11, III, IV and X. Of these, however, only the modifications I to IV are fibrous and are therefore of interest for textile processing.
- the cellulose I god is used in a large number Found natural celluloses, as in celluloses from plants, bacteria, or algae cellulose II, is the most frequently used modification industrially, since it is contained in all regenerated celluloses.
- the crystalline modifications can be converted into one another
- Cellulose IV which can also be obtained by heating cellulose III, is a crystalline modification of cellulose, which is also found in many plants and in seaweed
- No. 5,322,524 describes cellulose fibers with improved resistance to abrasion and improved permeability to chemicals, the crystal lattice of which consists of highly stable cellulose III and cellulose IV, in particular cellulose III
- US Pat. No. 4,871,370 also discloses a process for the production of cellulose fibers by which fibers with improved resistance to abrasion and improved permeability to chemicals are obtained.
- the cellulose fibers are treated with ammonia vapor at a defined pressure and temperature, with highly stable, crystalline cellulose III is obtained
- the crystalline cellulose III can further be converted into cellulose IV
- cellulose fibers of the amine oxide type (lyocell fibers) which are precipitated in water have a higher degree of plasticity and longer and thinner crystals than cellulose fibers of the viscose type
- a high degree of cellulose is disadvantageous, however, because the fibers show an increased property as an undesirable property
- the object of the present invention is therefore to provide a shaped body which contains cellulose and has a low tendency to fill, and a process for its production
- a shaped body comprising cellulose with a degree of stability of ⁇ 45%. Furthermore, the task is solved by a shaped body comprising cellulose with a proportion of cellulose IV of at least 50%. Another solution to the task is a shaped body comprising Cellulose with a degree of conductivity of ⁇ 45% and a proportion of cellulose IV of at least 50%
- the cellulose has a degree of crystallinity of ⁇ 36%, in particular ⁇ 34%. Furthermore, the proportion of cellulose IV is preferably at least 70%. The rest of the cellulose is preferably in the form of cellulose II
- the shaped body can contain a material from marine plants and / or shells from marine animals, such as Ascophyllum nodosum, Lammana digitata or üthothamnium calcaraeum, particularly preferably Ascophyllum nodosum.
- Ascophyllum nodosum differs from üeumothamnium calculus in terms of the composition of the additives due to a higher proportion of organic material
- the additive is preferably contained in an amount of at least 3% by weight, preferably 5 to 25% by weight, in particular in an amount of 8 to 12% by weight, based on the cellulose content
- the molded body according to the invention can be selected from the group consisting of containers, foils, membranes, fabrics and fibers.
- the fibers can be staple fibers, monofilaments or continuous filaments If the shaped body according to the invention is a fiber, the fiber can be a lyocell, viscose or carbamate fiber, particularly preferably a lyocell fiber
- the shaped body is preferably used as packaging material or fiber material. Furthermore, the shaped body according to the invention in the form of fiber material can be used as a mixture component for the production of yarns or for the production of nonwovens or woven fabrics
- the molded body is used in a preferred embodiment in the form of fiber material for the production of nonwovens or fabrics, wherein in the nonwoven fabric or fabric an additional component is selected from the group consisting of cotton Lyocell, rayon, Carbacell polyester, polyamide, cellulose security , Acrylic polypropylene or mixtures thereof is present
- the solution to the problem is also a method for producing a shaped body, comprising the following steps
- N-methyl-morphohn-N-oxide is preferably added
- the molded body produced can be washed out and treated in step (D) for further treatment.
- Aftertreatments can be, for example, bleaching processes, processes for adjusting the fat build-up or other impregnation processes with chemicals Washed out with water or on the already dried in a chemical and mechanical manner
- the molded body produced by the incorporation of algae material has a high porosity, which can be used positively for the corresponding aftertreatment processes to adjust the product properties of the molded body. It was also possible to demonstrate an improved absorbency of the fibers produced according to the invention
- the fibers were cut into 40 mm stacks and washed solvent-free and with a 10 g / l softener (50% Leomin OR-50% Leomin WG (nitrogen-containing fat acid polyglycol ester Fa Clanant GmbH)) at 45 ° C or the fat layer applied for better fiber processing and dried at 105 ° C. After drying, a fiber moisture of 11% was set. An additional bleaching process before drying was not carried out in this case
- the x-ray degree x c was determined by means of X-ray wide-angle examinations (WAXS). Measurements were also carried out with X-ray small-angle diffraction (SAXS). Pores in the order of magnitude of approximately 2 nm to 100 nm were detected
- a spinning solution was prepared analogously to Comparative Example 1.
- the spinning solution was spun into fibers, in contrast to Comparative Example 1 the temperature of the spinning block was set to 95 ° C. and the temperature of the nozzle to 105 ° C.
- the faded coulter was included in the air gap between the nozzle and the falling bath humid air (temperature 20 ° C, humidity 70%) blown ⁇ The experiment was otherwise carried out as in Comparative Example 1
- Example 1 Analogously to Example 1, 2 951 g NMMNO (60.84% ⁇ g), 305 g MoDo, DP 500, dry content 94% 1 8 g propyl gallate (0.63% based on the cellulose content) and 17.5 g of the in Example 1 mixture used (in total 6.1% based on the cellulose content) mixed and heated to 94 ° C. A spinning solution with a solids content of 12.9% and a viscosity of 7 801 Pa • s was obtained. The spinning solution thus produced was spun into fibers as in Comparative Example 1
- the Lammana digitata mixture used in this example differs from the Lithothamnium calcaraeum mixture mainly by one higher potassium content and a lower calcium content ( ⁇ 12 6% to -35%) A spinning solution with a solids content of 12% and a viscosity of 7,218 Pa • s was obtained. The spinning solution thus produced became fibers as in Comparative Example 1 spun Table 6: Composition of Lithothamnium calcaraeum
- Example 1 Analogously to Example 1, 3 315 g NMMNO (60.5% ⁇ g), 325 g MoDo DP 500, dry content 94% 1.9 g propyl gallate (0.63% based on the cellulose content) and 24 4 g of the mixture used in Example 1 Ascophyllum nodosum (in total 8.0% based on the cellulose content) were mixed and heated to 94 ° C. Three different mixtures were prepared, the mixture Ascophyllum nodosum impregnated with mitialuminum impregnated with NMMO, washed free of NMMO and subjected to the tests in dried form A spinning solution with a solids content of 12.5% and a viscosity of 5 801 Pa • s was obtained in each case. The spinning solutions thus produced were spun into fibers as in Comparative Example 1
- Table 8 Fiber data of the fibers produced according to Example 4
- Table 9 Further test results of the asers produced according to example 4
