Cut resistant characteristic of weft plain-knitted structure for protective clothing

PurposeThe paper aims to study cut resistant property of basic weft plain-knitted fabric for protective clothing.Design/methodology/approachEffects of fiber materials, fabric direction and knitting technology (sinking-depth) were explored, respectively. Cut process of fabric was tracked and the theoretical analysis was provided to evaluate energy transferring of cutting. Fiber-based cut behavior was observed by SEM images. Deformation energy stored in the loop due to yarn bending was regard as initial elastic potential energy of the fabric, which was related to loop structure.FindingsCut resistance of the fiber material was the dominant factor for cut resistance of weft plain-knitted fabric, while unit loop structure played a critical role in improving cut resistance.Social implicationsCut resistance of the fiber material was the dominant factor for cut resistance of weft plain-knitted fabric, while the unit loop structure played a critical role in improving cut resistance.Originality/valueThe paper provides theoretical support of developing flexible protective clothing.

The Role of Yarn Counts and Polyester/Cotton Blends in Comfort of Knitted Fabric

There have been three major concerns regarding the clothing comfort, psychological, sensorialand thermo-physiological comfort. However, there is lack of work on thermo-physiological comfort ofknitted fabric. Hence the present study is conducted to fulfill this gap by analyzing physiological comfortin sense of air permeability, absorbency, vertical wicking and drying time of plain knitted fabric. Clothingcomfort is mainly affected by type of fibres, yarn properties, structure of fabric, finishing treatments, andclothing conditions. In this study the effect of various yarn counts and polyester/cotton blend ratios on thecomfort of knitted fabric has been analyzed using Statistical Package for the Social Sciences (SPSS). Itis depicted from the results that the selected variables put direct influences on the thermo-physiologicalcomfort of the knitted fabric. The increasing share of polyester in the blend and the fine count for yarnput negative impact on the comfort of the knitted fabric.

Analysis of physical properties and structure design of weft-knitted spacer fabric with high porosity

The main content dealt with in the paper is to present a kind of weft-knitted spacer fabric with high porosity. It is a kind of three-dimensional textile fabric with a sandwich structure that consists of a middle layer of multifilament and two outer layers of plain-knitted fabric. Compared with traditional warp-knitted spacer fabric as cushion mats, weft-knitted spacer fabric is well used as apparel for good softness, thermal/moisture comfort, and air permeability. Therefore, three structures were designed and nine samples were prepared by choosing plain-knitted fabric as the outer layers and selecting soft and thin multifilament as a middle layer. Experimental results show that this kind of weft-knitted spacer fabrics has high porosity, greater than 86%, and also demonstrate that the weft-knitted spacer fabric is suitable for comfortable apparel based on experimental results of air permeability, compression properties, stiffness, and thermal insulation properties.

Geometrical and mechanical modelings of dry relaxed slack plain knitted fabrics for the benefit of technical textile applications part II: Mechanical modeling induced by friction

In this work, based on the geometrical model given in Part I, a mechanical model is created for dry relaxed slack plain knitted technical fabrics including the three-dimensional friction effects. The equilibrium of forces and moments applied on a loop are written by using the elasticity theory of thin rods. Through this model, it is shown that a dry relaxed plain knitted fabric can be in a stable state induced by friction. The application of the model was carried out on E-glass technical fabric, which was also used in Part I as its dimensional properties were obtained through the created geometrical model. In the current part, Part II, the mechanical properties of this fabric are obtained and discussed as an exemplary application.

The Comfort of Knitted Fabric as Affected by its Structure

The present study was carried to investigate the effect of various knitted fabric structure on itscomfort related properties. It was observed that, all comfort properties of knitted fabric have direct relationto its structure. The plain knitted fabric was found best for optimum comfort.
