Benefits of technology
The patent describes a fabric that has antimicrobial properties, meaning it helps prevent microorganisms from growing or multiplying on the fabric. This reduces the risk of spreading bacteria to other patients, healthcare workers, and others. The fabric is also comfortable to wear, requires less energy to dry, has high strength, and is stable in size. Additionally, it does not release antimicrobial substances into the environment.
Problems solved by technology
Healthcare-associated infections (HAI) are a major problem worldwide.
Washing and drying of staff uniforms thus require a significant amount of energy.
Frequent washing and drying also wear at the fabric and reduces the lifetime of the clothes.
However, such textiles may be prone to leaking silver ions into the environment, in particular in connection with washing, and thus have a significant detrimental effect on the environment.

example
[0053]Yarns and threads were produced according to the invention and used as warp and weft in the production of a woven fabric according to the invention. The warp comprised 35% hemp, 20% polyester, 20% cotton, and 25% fibre comprising porous particles. The weft comprised 55% hemp, 20% cotton, and 25% fibre comprising porous particles.
[0054]The properties of the fabric were tested for requirements under the Swedish standard for textiles for healthcare and social services facilities (SIS-CEN / TS 14237:2016), which in turn reference standards set by the International Organization for Standardization (ISO).
[0055]Dimensional change was tested in accordance with BS EN ISO 26330-1A and was found to be −0.5% to −1.0%, which is within the tolerance of ±3.0% according to Swedish standards.
[0056]Tensile strength was tested in accordance with ISO 13934-1 and was found to be ˜700 N (warp) and ˜425 N (weft), which is well above the requirements of 400 N set by Swedish standards.

Abstract
The present invention aims to provide a fabric useful in production of clothes and other textile articles, in particular for use in a healthcare environment such as hospitals, long term care facilities, etc. The invention relates to a yarn consisting essentially of cotton fibres, hemp fibres, and fibres comprising porous particles, and to threads and fabrics comprising such yarns, as well as to the use of such clothing as healthcare staff uniforms. The yarn and fabric may further include at least one metal wire usable as a temperature sensor.
Description
FIELD OF THE INVENTION[0001]The present invention relates to the field of textiles and garments, and in particular to new combinations of fibres in production of yarns and fabric made from such yarns.BACKGROUND[0002]Healthcare-associated infections (HAI) are a major problem worldwide. It has been reported that about 6% of in-patients in Europe present with one or more healthcare associated infections during the hospital stay. In long-term care facilities, the prevalence of HAI has been estimated to 3.4% (European Centre for Disease Prevention and Control; Technical report: Assessment of infection control, hospital hygiene capacity and training needs in the European Union, 2014). The cost for hospital acquired infections in Sweden is estimated to 6.5*109 SEK per year.[0003]The ability of bacteria to survive on various surfaces in a hospital is a key aspect in transfer of bacteria in a hospital setting and textiles are recognized as the second largest cause of HAI. It has been found t...
