ABSTRACT
-------------------------------------------------
This study compares the absorbency of two different cotton brands, Cleene and SM Bonus. The two brands are chosen based on the price differences, and analysis has been conducted to show if significant differences on the absorbency exist between these brands to justify the large price difference, P27.50. The cotton brands are subjected to two types of liquid: water and astringent, where one gram of cotton is completely submerged for five seconds. The amount of liquid absorbed by the cotton brand is the response variable, and is measured by subtracting the final weight of liquid from the initial weight. Twenty samples have been subjected to the two conditions, therefore having five replicates for each combination of factors. The experimental data showed a significant difference among the results. Upon further examination, it was found out that the difference occurred due to the type of liquid used. The rate of evaporation and the densities of the liquids have contributed largely on the rejection of the null hypothesis. Thus, the two cotton brands have no significant difference in their absorbency capacity. Analysis and implications of the results were discussed and recommendations are made on the basis of the experimental results.
KEY WORDS: comparison of absorbency, price differences, liquid types
INTRODUCTION
Absorbency may be considered as the attribute of cotton that is primarily considered as it addresses the main function of the said product.
With the extreme difference in the prices of cotton brands available in the market, this study was conducted to know if differences in absorbency between two certain brands exist. The first brand is Cleene, which costs P49.75 and the second, SM Bonus which costs P22.25. In general, this
