The effect of knit structures with tuck stitches on fabric properties and pilling resistance

The patterns of knit fabrics are designed by loops, tuck stitches, and float stitches and their combinations. The tuck stitch has important influences on fabric properties. It increases the fabric’s weight, thickness, and width and makes the fabric more porous than other fabrics. In this study, to determine the effects of knit structures which are made from the same cotton yarn with tuck stitches on fabric properties and pilling resistance, circular knit fabrics with different locations and number of tuck stitches were produced and dyed under the same conditions. In the evaluation process of the results, graphs were drawn and variance analyses were performed. At the end of the study, important findings were determined. The number and location of the tuck stitches and stitch length are effective factors on the structural, physical properties and the pilling resistance of knit fabrics. The fabrics with tuck stitches have much higher porosity, weight, and thickness compared to single jersey fabric. The dyeing process increases fabric weight. Single jersey has the lowest pilling resistance in comparison to fabrics having tuck stitches. The fabrics having more pores and larger pores show higher resistance to pilling. Dyeing and finishing processes decreased the pilling resistance of fabrics.

Regression model for predicting the air resistance of fabric made from doubled yarns and with different weave structures

The purpose of the investigation is to model the effect of doubled yarns produced from conventional and compact yarns in three different combinations and weave structures on the air resistance of fabrics. A series of woven fabrics differing only in weave structures and having the common count and fabric sett was produced from three types of doubled yarns, namely compact/compact, conventional/conventional and compact/conventional. The hybrid combination was produced principally to reduce the cost of manufacturing doubled yarns. Essential data for the fabrics such as CFF (crossing over firmness factor), FYF (floating yarn factor), FFF (fabric firmness factor), mass per unit area, thickness and porosity were determined. Air resistance was determined by performing the standard test KES-F8 API. Analysis of the results in respect of fabrics produced from the compact/compact, conventional/conventional and conventional/compact yarns shows a strong correlation between the air resistance, porosity, CFF, FYF, FFF, mass per unit area and thickness (R = conventional/conventional 0.97, compact/compact 0.861, conventional/compact 0.974) and the generated statistical models have given the satisfactory prediction of air resistance. Among the parameters, thickness exerts a strong influence on the air resistance. It is concluded that in order to predict air resistance, a number of parameters are needed and any conclusion which has been drawn using only CFF and FYF should be treated with caution. Also the possibility of cost saving as a result of using hybrid doubled yarn has been pointed out.
