Abstract
Purpose
The aim of this paper is to study the operator activities in garment industry and the percentages of distribution of operations and to analyze the personal and delay allowances by observing the operations and deriving the ratios within a manufacturing period.
Design/methodology/approach
A work sampling technique is used. Relevant reports (1978‐2004) are studied to give the basis and methodology of the technique. In accordiance with work sampling techique, the operations to be observed in a sewing room are defined, the number of observations and observers required for each day and the procedure for making observations are determined and the distributions of work flows are calculated.
Findings
It is found that 72.7 per cent of working time in an general sewing room was spent for productive activities and 23.2 per cent for personal and unavoidable delay allowances.
Practical implications
Work sampling technique gives information about personal and delay allowances in a work flow of any sewing room. When the distributions of activites are determined, it is possible to find which activities are most responsible for low efficiency. For this purpose, standard operations time in a sewing room should be determined by time measurement studies and work flow should be organized.
Originality/value
This paper deals with an actual sewing room and gives general information about the distributions of activites in work flow which should be used for organization of any sewing room.

Abstract
Purpose
The aim was to prepare antibacterial microcapsules and transferred to denim and non-denim (canvas) trousers.
Design/methodology/approach
For this purpose, lavender and sweet almond oil as active agents were encapsulated with ethylcellulose shell with a spray dryer method and carried out capsule optimization studies.
Findings
The particle diameter of the capsules ranged between 0.61 and 8.76 µm, SPAN value was 1.608 and the mean particle size was 4 µm. The mass yields of capsules ranged between 35.0 and 75.4 %w/w. Denim fabrics were treated with prepared capsules by exhaustion and spraying methods. It was seen that microcapsules provided a reduction of bacteria by over 97% against both Staphylococcus aureus and Escherichia coli and the fabrics still showed an antibacterial effect after five washing cycles.
Originality/value
When application methods were compared, the spraying method was found to be more sustainable process than exhaustion and could be used as an alternative for reducing energy consumption and capsules could provide antibacterial properties to the fabrics.
