Abstract
Predicting properties of end product from known properties of raw material is an important part of quality control in manufacturing. Main concept in this research is to reach a specified property of end product from known properties of raw material by attaining response surface designs with feasible region. The Ne20–19.21 T/inch yarn breaking strength (response, desired value 450 cNs) is acquired from cotton fiber properties (variables). The relationship between response and variables are obtained in response surface drawings and contour plots. The area showing the desired value in contour plots are colored in lilac and are intersected to obtain the feasible regions. By reading backwards from the feasible region borders, the variable value ranges are reached which will give the desired value of the response is obtained. When this information to start the yarn production is ready, the cotton lots containing these fiber property value ranges will be bought or from raw material in hand we will be read which yarn breaking strength will occur at the end of production. It was concluded that response surface designs with feasible region are quick, practical, and effective tools, provide valuable results, contribute a lot to quality control, and are beneficial in textile quality control.
Highlights
Textile engineering comprises manufacturing of apparel and home textiles used in daily life together with technical textiles
The results of response surface designs, applied to yarn breaking strength and the properties of fibers forming the same yarns, which consists of response surface drawings, contour plots, lilac colored contour plots, and feasible regions are given and are discussed
Yarn breaking strength (BForce) is taken as the response and response surface design with feasible region is applied as variables of cotton fiber properties which are fineness/micronaire index (Mic), maturity index (Mat), length (Len), fiber length uniformity index (Unf), short fiber index (SFI), fiber breaking strength (Str), fiber breaking elongation (Elg), moisture content (Moist), reflectance (Rd), yellowness (b), trash count (Tr_Cnt) and trash % area (Tr_Area)
Summary
Textile engineering comprises manufacturing of apparel and home textiles used in daily life together with technical textiles. Which kind of textile it is, from the point of view of textile production, quality control is very important in entire of them. The product has to possess properties in accordance to the areas where that textile product will be used and have to be welcomed by the people using them. In order to end up with a textile product with the properties preferred in the area of its usage, at the very beginning, the raw material chosen has to conform such properties to achieve the preferred properties at the end product. It should be indicated here that quality control gained more importance in due time with the shortage of raw material, and lowering the costs because of high competitiveness in the market
