Influence Of Enzyme And Silicone Wash On The Physico-Mechanical Properties Of Non-Denim Twill Garments
Garments washing is one of the most important finishing treatments applied on apparels which have vital use to create special outlooks and improving the fashion. Technologically washing is one of the most important fashion elements for clothing industry and production of washed garments depends on the machine quality. In order to achieve an optimum effect of washing process, on the woven fabric in different washing time, Enzyme Wash and then Silicone wash were carried out for cotton fabric. However, there are some of the comments that when the garments have longer washing time, use of the chemical on the washing procedure will affect the physical and mechanical performance. The aim of this study is to determine the effects of industrial enzyme silicone wash combined with silicone wash. For this study currently fashionable regular Non- denim (100% cotton with twill 3/1 weave construction) trouser was chosen. The selected Non-denim trouser has been processed by enzyme and then silicone wash. In order to evaluate the washing effects on Non-denim trouser, changes of fabric handle, fabric specification (ends/inch, picks/inch, surface density, warp & weft yarn linear density), fabric strength has been determined during and after washing.
SURVEY ON DIFFERENT CLASS OF WASHES IN KNITTED FABS
This paper deals with three types of washing (enzyme, softener, Silicone) effects on 100% cotton Single Jersey T-shirt, Slub Single Jersey T-shirt, Double Lacoste (5% Lycra) Polo shirt, Single jersey CVC (T-shirt) and PC single Jersey (T-shirt). Typical industrial washing procedures and techniques were followed and then physico-mechanical properties were analyzed under standard condition. It is observed that after washing, weight of each garments has increased from 5% to 36%; stitch length of the constituted fabric has decreased from 1% to 10% approximately; CPI has increased 23% for CVC fabric only for enzyme treatment and for other process it has a little bit or no wash effects. Same effects found for WPI except 100% cotton and Double Lacoste. Shrinkage property both for lengthwise and widthwise remains the same except CVC and Double Lacoste knitted garments and spirality has almost unchanged except 100% cotton and slub fabric. Both the dry and wet rubbing properties have improved after any types of wash except 100% cotton on Silicone wash. Water absorbency property has increased; pH of all the samples is under controlled and lies between 4.5 and 5.0. But there is no significant change of colorfastness to wash and stain after these washing treatments.
Performance and mechanisms of fire retardants in polymers—A review
Abstract The fundamental mechanisms by which fire retardant additives can interrupt the self-sustained combustion cycle of organic polymers are reviewed. Evaluation of fire retardant performance and methods used for mechanism assessment are discussed. Examples are given of recent mechanistic studies of halogen-based and intumescent systems indicating that some previous generalisations should be revised. It is shown that a deeper understanding of fire retardance mechanisms acquired through detailed thermal degradation studies is the only way to answer the ever increasing demand for polymeric materials characterised by minimised overall fire hazard.
