Denim fabric (jeans) is a very popular fabric among young people in outwears especially in trousers. It is also considered one of the most important elements of fashion and clothes industry in the modern age. The current study deals with 100 % cotton jeans fabrics, and it was a comparative study of some physical and mechanical properties of denim fabrics which produced with vertical pique, and run some lab tests of samples for research and study the effect of research variables on some physical and mechanical properties of the research samples. Here the research division as follows:
First: (Definition of the research & its subjects): Includes introduction, search problem, objectives, assumptions, limitations and its methodology.
That the problem of research where the use of vertical and horizontal pique weaves instead of the traditional twill to add a new look for denim fabrics with a new surface feel and touches which increases the efficiency of this type to use.
Second: (Divided into three main sections):
Part Ι: Previous studies through divided into four chapters, as follows:
Chapter 1: (Cotton): It includes a study of the cotton material used in research and its most important properties.
Chapter 2: (Denim Fabrics “Jeans”) It includes a general study of the history and the weaves of denim, and the stages of denim manufacturing.
Chapter 3: (Pique) It includes a study of some of the important definitions of the Pique weaves and some of its types.
Chapter 4: (Rapier Machines) It includes a general study of rapier machines used in the production of research samples.
Part ΙΙ: Practical experiments and laboratory tests through divided into two chapters, as follows:
Chapter 1: (The executive specifications of the fabrics produced under study) that the researcher implemented (40) experiments using warp yarns with count 16/1 Ne (cotton 100 %) and 40 end/cm for warp density. For weft yarns (cotton 100 %) with different counts on picanol optimax rapier looms 4- R- 220, that the experiments have been divided as follows:
• 24 trials for group (A) using different variables: Weft count (8.1/1 – 12/1 – 13.5/1) Ne & Mechanical picks/ cm (20 - 24) & Number of ends/picks for cord of pique & type of pique (6 ends, 8 ends for vertical pique & 8 picks, 10 picks for horizontal pique).
• 16 trials for group (B) with weft count 8.1/1 Ne using different variables: Mechanical picks/ cm (20 - 24) & Number of ends/picks for cord of pique & type of pique (6 ends , 8 ends for vertical pique with effect on weave structure & 8 picks , 10 picks for horizontal pique with effect on weave structure).
Chapter 2: (Laboratory tests): it deals with the laboratory tests carried out on the fabrics produced under the research.
Part ΙΙΙ: it deals with the following:
• The results of the researcher through the laboratory tests conducted on the research samples, as the following laboratory tests were performed: (Weight of fabric- Stiffness- Elongation “warp, weft” - Pilling- Abrasion- Tensile Strength “warp, weft” - Tear Strength “warp, weft”).
• The statistical method was used to analyze the results.
• This is followed by a presentation for the most important results of the theoretical and practical aspects of the research, and finally the recommendations proposed by the researcher.
