The effect of some Structures of weft knitted jacquard on some Functional properties of Outwear Fabrics.

Due to the importance of design in the knitted fabrics and using some structures to show the aesthetics of the design, that’s why the research had tackled the use of jacquard as one of the executive methods of weft knitted fabrics and employing them in Outerwear Fabrics . And these executive methods may affect some of the properties of the outer fabrics. That’s why this research aims to doing an experimental study to show the effect of some executive methods for producing the Weft Knitted Jacquard Fabrics. The importance of this research becomes clear through studying the effect of this on the quality of the final product and how far its suites some natural and mechanic properties. Some of the fabric samples have been produced in the following variables: - The different executive methods ( Stripping – Pique 1:1 – Pique 2:2 – The double closed - The double vicious 1:1 – The double stripping – The stripping vicious from back). - A gauge (7) flat knitting machine has been used with an acrylic fiber material no. 28/2 English. After carrying out the fabric samples and doing some lab tests on the produced fabrics under research to specify its different properties and the relationship between these properties and the variables of the study ,Then analysis the results statistically using the vary analysis and quality evaluation. The study come to the following results:- 1- The weft knitted jacquard executive methods have an effect on the natural properties of the fabrics ( The number of courses – the number of wales – the thickness – the weight of square meter). 2- The weft knitted jacquard executive methods have an effect on the mechanic properties of the fabrics ( Bursting resistance – The air permeability) 3- Sample number (5) (The double vicious 1:1) is the ideal sample for the most natural and mechanical properties and it become first. 4- Sample number (6) (The double stripping) is the least for the all for the natural and mechanical properties and it become the seventh
