Definitions
- the present invention relates to the use of a regenerated cellulose fiber obtained by the viscose process in flame retardant products.
- Flame retardant viscose fibers have many uses such as e.g. in safety clothing; Mattress stuffing; Interior fabrics, etc. and are for general safety.
- Such aftertreated textiles / fibers but have only a limited wash resistance.
- the crosslinking chemistry used produces residual amounts of formaldehyde, which is harmful to health.
- the crosslinking reaction causes embrittlement and stiffening of the fibers / textiles.
- the object of the present invention is to provide a low-cost and effectively effective flame-retardant fiber which is easy to process in the usual textile processes.
- This object is achieved by the use of a regenerated cellulose fiber incorporating carboxymethyl cellulose in a flame retardant product.
- CMC carboxymethylcellulose
- Viscose fibers with a content of carboxymethylcellulose are known. It is a mixed fiber, which is obtained by the spinning of carboxymethyl cellulose in the Viskosepinnmasse. Such fibers have also been produced commercially ( US 4,199,367 A . US 4,289,824 A ).
- a Viskosepinnmasse is prepared by the usual methods.
- An 8-12% by weight solution of carboxymethylcellulose (CMC) is added to the dope immediately prior to spinning, so that the desired amount of incorporation relative to underivatized cellulose results.
- Post-processing and drying are carried out by the usual methods.
- the proportion of incorporated carboxymethyl cellulose in the regenerated cellulose fiber is preferably 5% by weight to 50% by weight, more preferably 15% by weight to 40% by weight, most preferably 20% by weight to 30% by weight, based on underivatized cellulose ,
- the carboxymethylcellulose may be a commercial product having a degree of substitution DS of 0.6-1.2, preferably 0.65-0.85 and a viscosity (2% solution, 25 ° C) of 30-800 mPas; preferably 50-100 mPas.
- the CMC-containing regenerated cellulose fiber used in the present invention will hereinafter also be referred to as "viscose / CMC mixed fiber”.
- the fiber titer of the viscose / CMC mixed fiber is preferably from 0.5 dtex to 8 dtex, more preferably from 1.3 to 6 dtex.
- the fiber length of the viscose / CMC mixed fiber used according to the invention can be from 2 mm to 80 mm and depends in particular on the field of application. In particular, fiber lengths of 2 to 20 mm are suitable for a wetlaid process, and fiber lengths of 20 to 80 mm for a carding process.
- Viscose / CMC blended fiber preferably contains another flame retardant additive.
- This further additive may in particular be selected from the group consisting of halogen-containing additives, phosphorus-containing additives, aluminum and magnesium salts and polysilicic acids.
- the other additive may in manner known per se by one spinning in the viscose spinning in fiber incorporated (eg in the case of phosphorus containing additives such as Exolit ® 5060) or be subsequently applied to the fiber (such as in the case of alkaline solutions of an aluminum salt) ,
- viscose / CMC blended fibers used according to the invention differ in their properties - in contrast to some previously known flame-retardant viscose fibers
- CMC additive used for the fibers according to the invention
- the present invention also relates to a flame retardant product containing a regenerated cellulose fiber in which carboxymethyl cellulose is incorporated.
- the flame retardant product according to the invention is preferably characterized in that the proportion of incorporated carboxymethylcellulose in the cellulose fiber is 5% by weight to 50% by weight, preferably 15% by weight to 40% by weight, particularly preferably 20% by weight to 30% by weight. , based on underivatized cellulose.
- the flame retardant product according to the invention may preferably contain the viscose / CMC mixed fiber in a proportion of 10% to 100%.
- the flame-retardant product according to the invention is preferably selected from the group consisting of clothing, in particular protective clothing, home textiles, in particular mattresses, automotive textiles, filter materials and insulation material for the construction and automotive sector.
- Viscose / CMC mixed staple fibers with a proportion of 0% (zero pattern), 12% by weight, 20% by weight and 30% by weight of CMC based on underivatized cellulose were prepared in a manner known per se. The fibers were cut to a staple length of 40 mm.
- Rotor rings of 10g were made from the fiber samples.
- the rotor rings were then opened and pressed through a tampon calender.
- the produced tapes have a surface weight of about 238 g / m 2 (206-260 g / m 2 ) at a thickness of about 5 mm.
- For the fire tests specimens of size 8 x 2 cm were cut. The specimens were clamped horizontally or vertically and the free end of the sample was ignited with a Bunsen burner for a defined period of time.
- the patterns were already inflamed at 1 s flame time and then burned with a lively flame until complete combustion.
- Viscose fibers with 12% or 20% CMC (according to the invention):
- test piece burns in direct contact with the burner flame. If the flame is removed, the sample will extinguish immediately ("self-extinguishing"). In some cases, after removal of the flame, individual fibers protruding loosely from the test piece burned off the surface.
- the flame time was varied from 1s - 10s. All samples quenched immediately after removal of the flame. It only increased the proportion burned by prolonged contact with the burner flame.
