Developing a Polymeric Human Finger Sensor to Study the Frictional Properties of Textiles Part II: Experimental Results

Experimental studies conducted on a set of 1 X I rib knitted cotton fabrics using an artificial finger friction sledge are reported in this paper. In order to better simulate the actual to-and-fro reciprocating action of a human finger on a fabric, a reciprocating sliding friction apparatus is used. The reciprocating motion is incorporate..

Weathering of Polyaniline-Treated Polyester Filter Fabrics

During shipping and storage operations, a filter medium may be subjected to UV light, cold, humidity, and even direct wetting. Hence, it is of utmost importance that the medium and semi-finished fabric is tested against all foreseeable stresses it may encounter before it reaches its final destination. In this work, polyaniline-treated pol..

Neural Network Predictions of Human Psychological Perceptions of Clothing Sensory Comfort

The objective of this'paper is to investigate the predictability of clothing sensory comfort from psychological perceptions by using a feed-forward back-propagation net work in an artificial neural network (ANN) system. In order to achieve the objective, a series of wear trials is conducted in which ten sensory perceptions (clammy, clingy..

Lattice Model for the Drape and Bending Properties of Nonwoven Fabrics

A discrete lattice model is presented to study the factors controlling the bending stiffness of nonwoven fabrics. The approach lends itself very easily to a detailed study of the importance of bonding pattern, laydown nonuniformities, fiber length, and orientation distribution. We find that nonwovens with a three-dimensional fiber orienta..

Effects of Mold Porosity on Fiber Distribution in a 3D Nonwoven Process

3D nonwovens can be formed using the air-laying principle. The fibers are deposited onto a porous mold and the web is then consolidated. Distribution of the fibers on the 3D mold must be regulated to produce a final product with the desired fabric evenness. This can largely be achieved by varying the local mold porosity. CFD modeling is u..

Properties of Specialty Yarns Based on Raw and Dyed Cotton

During the manufacture of specialty yams by blending dyed cotton and raw cotton, fibers damaged by the dyeing process degrade the physical properties of the specialty yams. For a raw cotton blended with a large amount of dyed cotton, the spinnability of the specialty yarn worsens due to the disparity of the raw materials, which makes fine..

Role of Baffles on Flow Fields Inside Wet-Lay Mixing Tanks and Their Potential Influence on Fiber Dispersion

Dispersion and separation of fiber bundles requires exposing them to a shear stress field to overcome interfiber frictional forces. To this end, fiber-mixing tanks are equipped with baffles to enhance shear and agitation in the water to help disperse the fiber bundles. The time and agitation required to separate and disperse the fibers de..

Relation Between Frictional Characteristics and the Strings' Ability to Make a Tennis Ball Spin

The spin of a tennis ball during play is an important factor. There are two kinds of racket strings, one that causes the ball to spin, and the other makes spinning difficult. The relationship between the spin behavior of a tennis ball and the mechanical properties of the strings is discussed. Rotations of the ball after impact are observe..
