AND CANNABIS PLANT
The Field of the Invention
The invention relates to cannabis fibre and cannabis plant extract for obtaining antimicrobial feature on textile surface.
Invention particularly relates to method of fabric application in sizing bath of fitocannabinoide and/or terpen derivatives obtained by extraction of body and leaves of cannabis fibre and cannabis plant to provide antibacterial/antifungal/antiviral feature onto textile surfaces comprising natural or synthetic fibre.
Background of the Invention
Today consumers’ awareness of importance of hygiene and harmful effects of microorganisms has caused change in their preferences. Technological developments achieved recently have enhanced quality standards of people as well as their expectations in comfort and cleaning. For that reason, interest in obtaining antibacterial objects of environmental friendly and natural plant basis and textile application in this line has increased.
Modern life and working conditions allows medium eligible for fast reproduction of microorganisms. Microorganisms exist in body, air, soil and all surfaces and reproduces fast when eligible conditions occur. Textile products cause allergic effects leading to infections in human body, decay of product, stain, odour occurrence and spreading of microorganisms in crowded media as they provide temperature., humidity and nutrient agent needed for survival and reproduction of microorganisms.
While it is required to keep under control the undesired odour occurring in textile products and non-pathogen microorganisms in appearance, it is highly important to prevent reproduction of pathogenic microorganisms due to their dangerous impacts on human health. Antimicrobial agent is defined as a natural, synthetic or semi-synthetic agent, bacteria, rust, yeast etc. killing microorganisms, preventing their reproduction. Antibacterial textile products are obtained by means of trapping into fibre polymer by adding antibacterial agents or transmission into textile product by finishing works. Anti-microbial agents used for antibacterial finishing works are transmitted into textile material by use of one of absorption, stretching, maximum liquor application, foam application, vacuum application, spraying transmission plasma and coating methods. Thus harmful effects of micro organisms are prevented.
There are thousands of chemical agents killing micro organisms. Most of them are natural agents such as herbal and animal extracts, arsenic, lead, tin, mercury, silver etc. However, they can be toxic to humans and environment in most applications. For that reason, an antibacterial agent to be used in textile industry should not only be of feature killing microorganisms but also safe for human and environment, and not adversely impact other features of textile material. Today heavy metals such as silver, zinc etc. used as antibacterial can cause toxic effect for human body and accumulation in body by time may lead to serious diseases. For that reason, studies on natural antibacterial plants have increased.
Cannabis fibre is a highly valuable and rare plant having superiorities in almost all use areas and allowing use thereof in whole and having economic value in various areas. For instance, it is discovered that it is more advantageous than concrete use when fibre and mineral mixture weight, strength and quality criteria are considered for use thereof in roof and wall materials. Moreover, structures where said mixture obtained from Cannabis fibre have low humidity rate and ambience temperature provides best insulation. All of those structures are eligible for recycling and do not cause environmental pollution, which is another essential superiority. Root systems are considerably strong against drought and pests.Their need for water is less than other fibre plants, they grow considerably fast and cultivation can be made in several geographies broadly. They have antibacterial feature as lignocellulosic fibre. For that reason, they are considerably eligible for use in production of antibacterial textile products and surgery materials. Reference literature indicating their natural antibacterial feature for yarns obtained from Cannabis fibres are available in product descriptions. On the other hand, it is hard to produce yarn in fine sizes because of its being in lignocellulosic structure and because of being body fibre, having high variations in fibre length, and displaying high flexibility rigidity . Mixture with cotton fibre for sake of reduce spinning and non-smoothness in yarn is a frequently used method. In order to provide Cannabis fibre antibacterial effectiveness onto fabric structure, it is needed to make development in the related art.

Cannabis is a wooden and one year plant from cannabinaceae family. It has two species today. They are Cannabis sativa and Cannabis indica. The one that is important for industrial applications and used in fibre production is Cannabis sativa. Cannabis is a renewable and sustainable nature and multi-purposed product and thus is a material becoming more important day by day in terms of scientific, sectoral and economic aspects. Having considerably broad areas of use in various sectors such as textile, medicine, paper, bio-fuel, cosmetics and automotive, cannabis is a plant being alternative to any area where petroleum and petro-chemicals are used and have superior features.
A method for application of extracts and fractions obtained by use of extraction from cannabis plant onto fabric in prepared finishing bath in order to provide antibacterial / antifungal / antiviral feature onto textile surfaces comprising natural or synthetic fibre and comprises process steps of i. Liquefaction of extracts obtained from cannabis plant from extraction treatment by mixing with fraction solvent at 1 :1-1 :50 volume rate and emulsifying by mixing with polyetylenglicole of 100-10000 molecule weight, ii. Transmission by absorption to fabric sample by polymeric binding in 0 - 100 g/L range in bath prepared with emulsion in concentration of 1 - 100 g/L range and drying fabric sample at 100 - 200 Ό range after ab sorption, iii. Putting 1 - 100 g/L thickening, 1-500 g/L polyurethane, 1 - 50 g/l fixer, 1 - 500 g/l distilled water together with coating paste onto surface of fabric sample by use of concentration at 1 - 100 g/L range of prepared bath and drying fabric sample at 100 - 200 Ό range.
Extraction process can be applied to both cannabis fibre and cannabis plant body and leaves. The treatment comprises drying of fibre and/or cannabis plant and leaves before extraction, grinding in mechanic grinder and brining into powder and preparations of various fractions by means of polar solvent extracts and liquid-liquid partition method from such extracts. Methanol, water and water/methanol of 1 :1 in volume are preferably used as polar solvent. While preparing fraction n-hexane, dichloromethane, ethyl acetate and n- butanole are preferably used as polar solvent.
For preparing polar solvent extracts, powder particle and polar solvent are mixed in a manner 15 ml. polar solvent onto 1 g powder particle. The obtained mixture is filtered by help of a filter and fully separation of solid particle from solution is provided. Polar solvent is evaporated from solvent rotavapor, the solvent in the amount equal to initially added one is added into remaining and mixed, evaporated in rotavapour and polar solvent is added again up to initially added amount and after evaporation in rota-vapour, extraction is ended.
While extraction is prepared to extract put into balloon after extraction process, distilled water in the amount equal to half of added polar solvent is added, solved in ultrasonic bath, then taken into separation cone and solvent to be prepared in amount of added distilled water is added and shaken. Separation occurs due to density difference between solvent used in extraction and solvent of which fraction is prepared. After 20 minutes solvent to be prepared from separation cone is separated and the process step is repeated 2 times. Fraction solvent separated during each repeat is collected in a single breaker.
Extracts obtained from extraction process is mixed with solvent used in fraction at 1 :1 — 1 :50 volume rate preferably 1 :10 and liquefied and mixed with poly- ethylene- glycol in preferably 400 molecule weight having 100 - 10000 molecule weight. The initially prepared bath is transmitted to fabric sample by absorption method with polymeric binder in 0 - 10Og/L range in 1-100 g/L range concentration. After absorption fabric sample is dried at temperature range of 100 - 200 °C. Woven fabric or knitted fabric or non-woven surface can be used as fabric sample in the process.
In another application sample 1 - 100 g/L concentration of bath, is used, 1 - 100 g/L of thickening (preferably 10 g/L) 1-500 g/L preferably 200 g/L polyurethane, 1 - 50 g/l (preferably 20 g/L) fixer, 1 - 500 g/l preferably 270 g/L distilled water is put together with coating paste onto surface of fabric sample and drying fabric sample is dried at 100 - 200 Ό range.
