Fibre properties are influential factors for yarn properties. Cotton, whose physical properties vary depending on the cultivation region, is still a very common fibre used in the textile industry. Properties such as fibre length, fineness, strength and maturity affect yarn tensility, evenness, imperfections and hairiness. Four different 100% cotton blends were used as raw material (American cotton, Aegean cotton, Urfa cotton, Greek cotton) to be converted into 20 tex compact yarns separately. HVI parameters of each blend type starting from the bale until the 2nd drawing passage machine revealed that yarn processing stages and machinery are influential factors for fibre the properties of fibres that are produced on a spinning line. Additionally ANOVA tests supported the idea that the evenness, tensility, yarn imperfections, and hairiness parameter of yarns produced from various cotton blends were statistically different. Principal Component Analyses (PCA) and the Correlation Matrix were also applied in order to analyse the relationship between fibre properties and compact yarn properties of different blends.

White and naturally colored organic cotton fiber usage and its production as textile end-products have been one of the new considerable efforts to reduce the waste generated during wet textile processing stages. This paper has focused on evaluation of the mechanical and air permeability properties of plain, twill and ribs fabrics made of unique white and naturally colored Turkish organic cotton types. Statistical evaluation of yarn and fabric properties was conducted using ANOVA statistical approach. According to statistical test results of two-factor ANOVA, cotton type and fabric weave structure parameters were generally significant factors on some mechanical and air permeability properties of fabric samples made of white and naturally colored cotton at significance level of 0.05. As a general result, white and naturally colored organic Turkish cotton utilized textile fabrics have given satisfying mechanical and air permeability property levels which reveal that those samples may be used for apparel garments.
