  • Patent number: 10125453
    Abstract: The present invention relates to a method of obtaining antifungal, anticandidal and antibacterial textile products. The objective of the present invention is to obtain an antimicrobial product, which enables to reduce the infectious diseases that are transmitted or spread by textile products, reduces extra cost and energy spent for ensuring hygiene, and increases hygienity of disposable textile products. A solution of triclosan, chlorhexidine and disodium octaborate pentahydrate is used in the method of the present invention. The said solution enables the hydrophobic textile products to be transformed into hydrophilic products and thereby enables the antimicrobial agents in the solution to be coded into the textile products.

  • Patent number: 10124085
    Abstract: The present invention relates to hygienic products such as sanitary pads and tampons, patient/adult diapers and baby diapers which are made antimicrobial. In the present invention, a mixture of glucopon, chlorhexidine gluconate and triclosan is obtained from the boron compounds called sodium borate, zinc borate, sodium perborate tetrahydrate, borax pentahydrate and disodium octaborate tetrahydrate; and this mixture provides antifungal, anticandidal, antibacterial and antiviral properties to the woven or non-woven textile products and hygienic products. Additionally, the said hygienic products are made hydrophilic by means of the invention.

  • Publication number: 20170135339
    Abstract: The present invention relates to a coating formulation which is developed for sterilization of annual and perennial plant seeds and agricultural implements. With the present invention; an antifungal, anticandidal, antibacterial and antiviral coating formulation containing zinc pyrithione, triclosan and carboxymethyl cellulose is obtained. Furthermore, thanks to the present invention, contaminations due to the areas of use of annual and perennial plant seeds and the silo, storehouse and warehouse surfaces, where the seeds are stored before seeding, can be prevented. The present invention can be used for sterilization of agricultural implements and equipment.

  • Publication number: 20150030532
    Abstract: The present invention relates to development of paint, plaster, cement and plastic construction materials containing silver, zinc and copper metal ion-charged zeolite ( 1/10 w/w). The new construction materials are antimicrobial and prevent microorganism growth and reproduction of fungi, yeasts and bacteria. The product, made from construction materials containing metallic ion-exchanged zeolite, provides hygiene by preventing microbial contamination in areas and surfaces for a long time. Furthermore, lifespan of the materials produced with this technology is longer since they will be protected from biological deterioration, corrosion and decays.

  • Publication number: 20140294905
    Abstract: This invention is about textiles which are equipped with antifungal, anticandidal and antibacterial properties. The aim of the invention is to attain antimicrobial textiles which reduces the incidence of infections communicated or spread by textiles, reduces the loss of extra cost and energy to ensure hygiene and strengthens the hygienic condition of disposable textiles. Textiles can be equipped with antimicrobial properties in three ways: In the first method, sodium borate is dissolved in methanol and is then fixed to the fabric. In the second method, sodium borate is dissolved in water and is then sprayed onto the fabric. In the third method, sodium borate dissolved in water and mixed with textile dye and applied as a dye. Antimicrobial properties of sodium borate are tested on 38 bacterial species, 9 yeasts and 1 1 fungi isolates based on disc diffusion assay.
