Abstract
Some effect of repeated laundering processes with different practical formulations of stain removal methods of blood and urine stains from 3 healthcare institutions (Ahmadu Bello University Teaching Hospital- Zaria, Aminu Kano Teaching Hospital- Kano and National Orthopedic Hospital- Kano) were carried out. Physical fabric properties such as breaking load, breaking extension, percentage shrinkage, moisture content and moisture regain as well as colour fastness were analyzed with the hospital white (bed-linen) and green theatre linen made from 100% woven cotton fabrics. Analyses of the sample after the 3rd, 6th and 9th washing cycles were investigated. The colour change in shades were evaluated from visual observation using the AATCC Evaluation Procedure 2 Gray Scale for Assessing Staining, which showed a yellowing effect on the white hospital linen (ABUTH) as a result of the continuous bleaching action on the repeated blood stained linen with a change in colour of 4 after the 9th wash. The breaking load values increased after every washing for all samples analyzed with the ABUTH hospital linen showing the highest breaking load values up to the 9th wash. The percentage shrinkage values also showed an increase in the shrinkage properties up to the 9th wash for all sample analyzed with the least shrinkage properties from the blood treated samples of the ABUTH hospital linen. The moisture content and moisture regain showed the highest percentage values with the blood treated samples of the ABUTH up to the 9th laundering. These attributes, specifically on the blood treated hospital linen from ABUTH amongst other samples analyzed showed an unequal property along the length and breadth of the fabric to a point of which the fabric stability and functionality becomes compromised thereby degrading the fabric. This study may help to improve the blood stain removal methods and fabric performances in hospital laundering.
