The purpose of this study was to assess the structural attributes of black and white Printed Printex Textile Fabrics in Ghana. The study adopted a factorial experimental research design. The three fabrics with black prints and white as base colours were purchased from the market. These three fabrics had the same designs but two had different fabric finishes and the third one had no finish (plain, embossed and plisse). Key soap purchased from the Ghanaian market and standard soap from Ghana Standard Authority were used for the study. A purposive sampling procedure was used in choosing the fabrics and soap for the study. Specimens totalling 219 were cut randomly from along the warp and weft directions of the Printex black and white cotton fabric with finishes (plain, embossed and plisse). The use of laboratory experiments and the apparatus used to experiment. The data obtained were presented using both descriptive and inferential statistics. The descriptive statistics (frequencies, percentages, means and standard deviation) were used as summary statistics of variables of the study. The one-way analysis of variance (ANOVA) was used to test for significant differences among three variables (three washing cycles), whereas the independent samples t-test was used to test for statistically significant differences between the performance of the fabric finishes under Key soap and the standard soap. The study indicated that differences in the attributes of the finishes caused differences in the structural attributes of the fabrics. This was because some of the finishes required certain structural attributes to bond well with the fabrics. The implication is that continuous washing weakens the structural attributes of fabrics which causes them to fail or weakens their resistance to stress tests. The study, however, found that differences in the structural attributes of the fabric finishes caused differences in the effects of washing on the selected fabric finishes. It is recommended that Printex Textile Limited should place critical emphasis on the weight of the fibres used in the construction of the fabrics. This was necessary since the study found that the fabric finish with the greatest weight performed better in tensile strength than those with the lowest weight. As a result, the use of fibres with high weight is expected to improve the use and care of the fabric finishes in terms of their ability to resist stress or tension during washing.

The tensile strength is an imperative properties and essential indications consumers’ look out for in purchasing a quality fabric. The objective of this study was to examine key soap on tensile strength in three washing cycles of selected Printex fabrics in Ghana. Quantitatively, the study adopted both experimental and factorial research designs. Materials for the study consisted of three fabrics with black prints and white as base colour were purchased from the market. These three fabrics had the same designs but two had different fabric finishes and the third one had no finish (plain, embossed and plisse). Six yards each of the Printex black and white fabrics with embossed, plisse and a third one which did not have any special fabric finish were used for the study. Key soap purchased from the Ghanaian market, and standard soap from Ghana Standard Authority was used for the study. Purposive and simple random techniques were used to select materials for the study. The main research instrument for the testing tensile strength was Universal tensile testing machine. Data were analysed with both descriptive and inferential statistics. The one-way analysis of variance (ANOVA) was used to test the hypothesis formulated to guide the study. The study revealed that continuous washing had degrading effects on the tensile strength. The implication is that continuous washing weakens the internal strengths of fabrics which cause them to fail or weakens their resistance to stress test. The study also found that continuous washing had degrading effects on the tensile strength of the selected fabrics. It is recommended that the Ghana Standards Authority should encourage soap producers to get their chemical compositions as close to those of the standardised soap as possible.

The study sought to investigate the Physical Properties of Fabrics: Chemical Compositions of Selected Detergents on Colourfastness of GTP Wax Print and ATL Wax Print (Indigo) in Ghana. A 3×2×2 factorial experiment which includes three washing cycles, the two detergents and two fabrics types were used or the study. A total of 146 specimens were cut randomly from along the warp and weft grain directions of ATL and GTP wax prints and subjected to washing and breaking at the laboratory using standard equipment. The data was analysed using Microsoft Excel 2007 version and the results were presented using means and percentage tables. One-way analysis of variance (Anova) was used to test the hypotheses formulated. The study revealed that there was no significant difference in the tensile strength between GTP and ATL wax prints after undergoing three washing cycles with Omo multiactive and Ariel enzymax. The degrading effect in terms of loss of tensile strength of Ariel enzymax on both wax prints was greater than that of Omo multiactive. There was no significant difference in the colour fastness between ATL and GTP wax prints after undergoing three washing cycles each with Ariel enzymax and Omo multiactive. It is recommended that both GTP and ATL fabric manufacturers should pay particular attention to the physical properties (such as thread count, fabric weight and weave type) when purchasing grey goods for further processing of their products. It is also recommended that, Ghana Standards Authority should make it compulsory for the manufacturers of washing detergents to indicate the correct chemical composition of their products on the packages.
