Abstract: Spinning triangle is a critical area that influences the physical and mechanical properties of yarn. Previous researchers have done several works related to spinning triangle by modifying yarn path primarily considering only one side diagonal yarn path meaning that either left or right diagonal yarn path. The others used single yarn count and twist level on different variety of raw materials. This research was produced cotton ring yarns by varying count (36 Ne, 40 Ne) and twist level (1014 TPM, 1080 TPM) using right and left diagonal paths in Z-twist direction. The yarns were tested and it was observed that 25%, 0.34%, 37% and 25% reduction in hairiness, CVm%, thin place and thick place respectively with slight decreasing of tenacity in left diagonal path yarn. In right diagonal path yarn there is 3%, 16%, 59% and 14% increasing of yarn hairiness, CVm%, thin place and thick place respectively with 10% reduction of tenacity. Therefore, the left diagonal path has a significant improvement of ring spun yarn quality in terms of physical properties. On the other hand, the right diagonal path yarn were deteriorated all the physical and tensile properties of ring spun yarn. This is occurring due to the mismatching of right diagonal path with Z-twist direction.Abstract: Spinning triangle is a critical area that influences the physical and mechanical properties of yarn.

Abstract: Adoption of small scale irrigation technology had unprecedented advantage for smallholder farmer to reduce poverty. It increases use of available water sources to get higher income and improves the livelihood of farmers. Improvement of livelihood of smallholder farmers has ample contribution to the development of the country’s economy. With high potential demand to these technologies, still there are number of problems in selection for agricultural production improvements. Therefore, our study with the objective of exploring factors affecting adoption of small scale irrigation technology (SSIT) and existing constraints in the study area had used qualitative and quantitative data analysis. Binary logistic regression model was applied to analyze direct survey of farmers SSIT adoption. Analysis result revealed that six factors were significantly and directionally affects the adoption of small-scale irrigation technology. Age and lack of credit institution are negatively significant whereas awareness, access to water, government promotion, and total income of household affects positively. Qualitative findings show that conflict between members of Farmers Irrigation Water Use Association (FIWUA), unavailability and lack of access to spare parts, topography of the district, irrigation technology technician, and lack of skill were among the constraining factors found to hinder small scale irrigation technology adoption and use. We found the fact that FIWUA act as facilitating medium in adoption and extension of small scale irrigation technology and the presence of association could be taken as opportunities available for small scale irrigation technology adoption enhancement. Overall, our findings revealed that small scale irrigation technologies are highly beneficial, and seen to have impact on the livelihood of farmers, so that the government and partner of the government working on rural livelihood improvement should have to take into account on improving farmers’ awareness and education on SSIT adoption through training and promotion in most parts of Ethiopia.Abstract: Adoption of small scale irrigation technology had unprecedented advantage for smallholder farmer to reduce poverty.
