The Assessment of Finishing Properties on the Mass per Unit Area, Pilling, Bursting Strength, and Wicking Behavior of Polyester Weft-Knitted Jersey Fabric

Finishes bring an alteration to the physical and comfort properties of the textiles. That’s why various finishes are used to impart various functionalities to the fabric surface. However, it may also affect some properties. The purpose of this study is to investigate the effect of various finishes on pilling, mass per unit area, bursting strength, and wicking behavior of the polyester weft-knitted jersey fabric. Herein, 100% spun polyester weft-knitted plain jersey fabric was exposed to different finish treatments to check their effect on the some physical and comfort properties of the fabric like mass per unit area, pilling behavior, bursting strength, and wicking properties of the weft-knitted jersey fabric. The fabric used was knit from 24/1, 100% spun polyester yarn on the single knit circular knitting machine. The developed fabric was washed on Fong machine. Finishes are applied on fabric by “Monofort Stanter” machine. The resultant fabric was characterized by random tumble pilling tester, bursting strength tester, and wicking tester to analyze their pilling grade, bursting strength, and wicking behavior respectively. A significant increase has been found in wicking behavior, mass per unit area, and bursting strength of the fabric after finishing treatments. Moreover, the wicking finish shows the highest reduction in pilling grade from 3.5 to 2.5. Significant improvement has been observed in bursting strength by all finish’s treatment. However, wicking finish treatment results in the highest increase in bursting strength of 4.2%. Significant improvement has been observed in the vertical wicking speed of all treatment except silicon finish which significantly reduces vertical wicking rate. However, the wicking finish (Recipe E) shows the highest increase in wicking rate by 13.75 times as compared to grey fabric.

Planned Ending of Therapy with a Couple Who Recovered Joy

This paper continues a conversation begun in this Journal between Pierre Cachia, as therapist, and Jill Scharff, his writing partner (Cachia & Scharff, 2013). Their account of a couple who lost joy focused on a turning point in the mid-phase of therapy. In this article, the authors focus on the planned ending of that couple's therapy. Ideas on ending from the individual analytic literature are discussed in terms of their application to couple therapy and various criteria are presented for consideration when assessing whether a couple is ready to finish treatment. Pierre Cachia presents the process of a late phase session to illustrate in detail the theory and technique of a planned ending of couple therapy. In a shared voice, the authors conclude by tying theory and clinical example together.

Role of Fiber Finish in the Conversion of Fiber to Nonwovens — Part 1: Need for an Unconventional Method to Evaluate Finish Performance as a Mechanical Process Aid

The processing of fibers in a free, non-bound state gives rise to a range of frictional behavior for a given process. The basic laws of fiber friction are reviewed. The finish treatment to the fibers mainly act as a lubricant and anti static agent. A critical review of the requirements of the finish treatment and the methods used to evaluate fiber friction and static charge generation are presented. The requirements of the finish treatment with respect to carding and needlepunching are also discussed. The ineffectiveness of conventional methods to evaluate performance of finish in such process and the need to measure performance of finish and optimize it for each of these processes is highlighted. Methods to evaluate the finish performance in carding and needlepunching will be presented in Parts 2 and 3.
