Definitions
- the present disclosure provides antibacterial regenerated cellulosic fibers and a process for preparing the said antibacterial regenerated cellulosic fibers.
- Cellulosic fibers are known for their good wearability. Cellulosic fibers are excellent in terms of sweat absorption because of their higher hydrophilicity as compared to other type of manmade fibers. Thus, cellulose fibers are suitable for use in outdoor clothes, sports clothes, shirts and undergarments that are in direct contact with the skin.
- antibacterial cellulosic fibers and their products having anti-bacterial property, odor-preventing properties or destroying properties as well as deodorizing properties.
- Such antibacterial cellulosic fibers should inhibit the inhabitation and proliferation of bacteria on fibers and be safe for human use while persistently maintaining antibacterial effects. Further, it is desirable that the antibacterial cellulosic fibers are made using approved chemicals (as per BPR or REACH).
- the antibacterial regenerated cellulosic fiber comprises a quaternary ammonium compound in a concentration range of 0.05-1% w/w on the regenerated cellulosic fiber.
- a process for preparing antibacterial regenerated cellulosic fibers comprises spinning a cellulosic solution through spinneret into a regeneration bath to obtain regenerated cellulosic fibers; washing the regenerated cellulosic fibers; treating the regenerated cellulosic fibers with a solution of quaternary ammonium compound having a concentration range of 0.1-1.5% w/w of regenerated cellulosic fibers to obtain treated regenerated cellulosic fibers; and drying the treated regenerated cellulosic fibers to obtain antibacterial regenerated cellulosic fibers.
- the present disclosure provides antibacterial regenerated cellulosic fibers and a process for preparation thereof.
- the antibacterial regenerated cellulosic fibers comprising a quaternary ammonium compound in a concentration range of 0.05-1% w/w on the regenerated cellulosic fiber.
- the quaternary ammonium compound is selected from the group consisting of dodecyl dimethylammonium chloride (DDAC), C8-C18 alkyltrimethylammonium chlorides (such as trimethyloctylammonium chloride, decyltrimethylammonium chloride and hexadecyltrimethylammonium chloride), soyalkyltrimethylammonium chloride, dicocalkyl dimethyl ammonium chloride, alkyl-benzyldimethylammonium chlorides (such as benzyldimethylstearylammonium chloride, benzylalkyldimethylammonium chloride orcocalkyl(2,4-dichlorobenzyl) dimethylammonium chloride, Dimethyl Benzyl Ammonium Chloride, OctylDecyl Dimethyl Ammonium Chloride, Didecyl Dimethyl Ammonium Chloride, Dioctyl Dimethyl Ammonium Chlor
- the antibacterial regenerated cellulosic fibers can be used to manufacture masks, scrubs, towels, doctor's coats, bath robes, pajamas, and uniforms for medical personnel; linens for use in hospitals; both sanitary and be perceived as sanitary; antibacterial finished socks required for foot ulcer prevention; antibacterial and antifungal finished socks and inner wear for military personnel; sportswear market comprising sport socks, gloves, sport bras, caps etc.; home textiles and furnishing; textiles; and antibacterial wipes etc.
- the products obtained by utilization of the antibacterial regenerated cellulosic fibers have improved antibacterial properties; controlled odor and staining due to bacterial growth; antibacterial activity of more than 99% after at least 20 wash cycles.
- Such products are obtained by environment friendly technology, as chemicals used in the process can be recycled in the process. Further, minimal amount of chemical is sufficient for antibacterial property. Additionally, the antibacterial regenerated cellulosic fibers retain antibacterial activity during downstream processing.
- the antibacterial regenerated cellulosic fibers can be an antibacterial viscose staple fiber, antibacterial modal fiber or antibacterial lyocell fiber.
- the antibacterial regenerated cellulosic fibers can be used for making woven, non-woven fabrics, fiber blends and fiber composites.
- the present disclosure also provides a process for preparing antibacterial regenerated cellulosic fibers, the process comprising spinning a cellulosic solution through spinneret into a regeneration bath to obtain regenerated cellulosic fibers; washing the regenerated cellulosic fibers; treating the regenerated cellulosic fibers with a solution of quaternary ammonium compound having a concentration range of 0.1-1.5% w/w of regenerated cellulosic fibers to obtain treated regenerated cellulosic fibers; and drying the treated regenerated cellulosic fibers to obtain antibacterial regenerated cellulosic fibers.
- present process provides a mechanism to open pores or striations on the surface of fibers to increase the surface area and infuse more active ingredients.
- pathogens such as: gram-negative bacteria, gram-positive bacteria, mold, mildew, fungus, spores, and viruses, and not be washed away during repeated launderings and uses.
- the regenerated cellulosic fibers are prepared by viscose process.
- the viscose was prepared by treatment of pulp sheets (high alpha cellulose, viscose grade pulp) with caustic soda, shredding the resulting in alkali cellulose, xanthating the alkali cellulose and dissolving it in a caustic soda solution.
- the viscose was then aged and spun by extrusion through orifices into a spinning bath containing sulfuric acid, sodium sulfate and zinc sulfate.
- the spinning bath being maintained at a temperature of 30-50° C.
- the filaments were withdrawn from the bath and passed over a first and second godets, then collected. After collecting the filaments, they were washed, desulfurized and bleached by conventional treatments.
- the regenerated cellulosic fibres can also be prepared by Lyocell process, wherein the cellulose was dissolved in N-methylmorpholine (NMMO) under heated conditions, usually in the range of 90° C. to 130° C., and extruded from a multiplicity of fine apertured spinnerets into air.
- NMMO N-methylmorpholine
- the filaments of cellulose dope are continuously mechanically drawn in air by a factor in the range of about three to ten times to cause molecular orientation. They are then led into water, to regenerate the cellulosic fibres namely Lyocell.
- extension of present invention to other cellulosic natural fibres such as cotton, Jute, hemp, flax etc., is conceivable for the person skilled in the art.
- Viscose Staple Fiber (VSF) or Modal or Lyocell made using standard manufacturing process does not give durable antibacterial performance.
- An antibacterial agent is used in Standard VSF or Modal or Lyocell manufacturing process to improve antibacterial performance of fiber.
- a small amount of chemical DDAC i.e. 0.05-1% on weight of cellulose fiber
- the resultant fiber was then evaluated for antibacterial performance in external biological laboratory as per standard test methods.
- Triclosan did not demonstrate any antibacterial activity at 0.5% concentration to weight of cellulose, but DDAC shows 100% contact inhibition of bacteria in spite of lower concentration of 0.15%.
- Viscose fiber treated with and without DDAC as an antibacterial agent Sr. No. Sample description Bacteria AATCC 100* JIS L-1902* C.E.-2.1 Viscose Fiber S. Aureus 97.7 2.07 K.pneumoniae 95 2.06 C.E.-2.2 Viscose Fiber-20 wash S. Aureus 0 1.79 K.pneumoniae 0 1.33 C.E.-2.3 Viscose Fiber --> Spunlaced to make S. Aureus 62.17 1.4 Nonwoven sheet K.pneumoniae 45.83 1.38 Ex.-2.1 Viscose fiber treated with 0.15% S.
- Comparative example C.E.2.1-2.3 show less antibacterial activity and after 20 washes the activity is lost completely. Also, activity is considerably reduced during the process of making nonwoven spunlaced sheets. Similarly, in examples 2.1-2.7 which are treated with 0.05 to 1% DDAC on fiber surface, shows more than 99% bacterial kill and further this activity is retained after 20-30 wash cycles and even after spunlacing process.
- Comparative example C.E.3.1-3.3 VSF fiber made by dope dyeing process i.e. dope dyed using black pigment
- the activity is reduced after 5 washes and do not show any antibacterial activity after 20 washes.
- example 3.1-3.3 which is sample prepared with addition of 0.15% DDAC on fiber surface, sample shows more that 99% bacterial kill and this activity is retained after 20 wash cycles.
- dope dyed VSF fibers were treated with 0.1% and 0.2% DDAC and then spunlaced. These fibers were then tested for antibacterial activity as per ISO 20743 and it was found that addition of 0.1%-0.2% DDAC (EX-4.1 & EX-4.2) on fiber surface, sample pass the test but fiber without DDAC (C.E.-4) fail the test criteria as per ISO 20743.
- Swatches of test and control specimens are inoculated with the organisms ( S. Aureus: 1.5 ⁇ 108 Cfu/ml and K. Pneumoniae: 1.5 ⁇ 108 Cfu/ml). After inoculation, the specimens are incubated for 18 hours. After incubation, the bacteria are eluted from the specimen swatches by shaking in known amounts of neutralizing solution.
- A the number of bacteria recovered from the inoculated test specimen swatches incubated
- C the number of bacteria recovered from the inoculated control specimen swatches Immediately after inoculation.
- An antibacterial regenerated cellulosic fiber comprising a quaternary ammonium compound in a concentration range of 0.05-1% w/w on the regenerated cellulosic fiber is disclosed.
- Such antibacterial regenerated cellulosic fiber(s) has an antibacterial activity of more than 99% after at least 20 wash cycles.
- Such antibacterial regenerated cellulosic fiber(s) retain antibacterial activity during downstream processing.
- Such antibacterial regenerated cellulosic fiber(s) is antibacterial viscose staple fiber, antibacterial modal fiber or antibacterial lyocell fiber.
- Such antibacterial regenerated cellulosic fiber(s) is used for making woven, non-woven fabrics, fiber blends and fiber composites.
- a process for preparing antibacterial regenerated cellulosic fibers comprises spinning a cellulosic solution through spinneret into a regeneration bath to obtain regenerated cellulosic fibers; washing the regenerated cellulosic fibers; treating the regenerated cellulosic fibers with a solution of quaternary ammonium compound having a concentration range of 0.1-1.5% w/w of regenerated cellulosic fibers to obtain treated regenerated cellulosic fibers; and drying the treated regenerated cellulosic fibers to obtain antibacterial regenerated cellulosic fibers.
- Such process(s), wherein treatment of the regenerated cellulosic fibers with the solution of quaternary ammonium compound is carried out by spraying, padding, dipping, pouring or soaking.
- quaternary ammonium compound is selected from the group consisting of dodecyl dimethyl ammonium chloride (DDAC), C8-C18 alkyl trimethyl ammonium chlorides (such as trimethyloctylammonium chloride, decyltrimethyl ammonium chloride and hexadecyltrimethyl ammonium chloride),
- DDAC dodecyl dimethyl ammonium chloride
- C8-C18 alkyl trimethyl ammonium chlorides such as trimethyloctylammonium chloride, decyltrimethyl ammonium chloride and hexadecyltrimethyl ammonium chloride
