Corresponding author’s Email: moyinul@yahoo.com Abstract: Silicone oil have wide spread applications in textile dyeing and finishing. In this paper four different samples of Silicone oil softeners were synthesized on the basis of a new recipe with different chemical ratio and each of them used on dyed and white cotton fabrics of knit and woven. Several tests have been done on Silicone oil like ionic surfactant test, solid content test, stability test etc. Although, several tests were done on the Silicone oil treated dyed and white knit and woven fabrics. From the test result of fastness test, color strength test, tensile strength test, Whiteness test etc. it has come out that it increases the fabric softness, flexibility, absorbency, increase abrasion resistance, crease recovery, gives excellent fastness properties etc. It can endow the textiles with soft, fluffy style. Proper stability and durability can reduce the problem of the roller sticky, floating oil. It is colorless and transparent thick liquid and easy to dilute. It has the excellent affinity to all kinds of fabrics including cotton knit fabrics, woven cotton fabrics, jute etc. The overall results come out with great prospect for silicone oil “Sample C” in textile finishing.

Introduction Silicone oil is the most important and common chemical in textile processing. Silicone softeners mostly used to get better softness properties on textile fabric. It improves the abrasion resistance of fabrics, mobility of fibres, tear strength of fabrics, soiling resistance and static protection. It also decreases yarn and fabric tensile strength by reducing fibre cohesion, reduce sewing thread breakage, pilling and flammability [1]. Softener can be classified by (a) Cationic softener (b) Anionic softener (c) Nonionic softener (d) Amphoteric softener and (e) Silicone softener. Cationic softeners have the best soft handle properties. It is a common application in exhaust methods. Cationic softener usually used in home laundry products. They have the good inherent affinity to all fibres. It is mainly used for color textiles. They have a tendency to yellow in comparison with non-ionic. Anionic softeners are used less due to less handle properties than cationic and nonionic. They don’t have the affinity to all fibers. They are suitable for padding application not exhaust. It improves good lubrication, strong antistatic effects, good rewetting, good foaming agents etc. because of their anionic groups. Nonionic softeners are less used than anionic softeners. They have good dispersing agent, high lubricity. Nonionic softeners are stable to temperature and high pH conditions. They are generally poor foamers and don’t yellow. Amphoteric softeners have high antistatic properties. They are very sensitive to skin and they have some ecological problem. Silicone softener improve the sample to give a silk soft hand, very good lubricity, crease recovery, tear strength, abrasion resistance etc. Silicone softeners are more expensive than fatty softeners. It shows excellent durability and temperature stability [2], [3], [4]. Silicones are the most versatile polymer known. This chemical adds value to the fabric by transforming the fabric handle to match the customer perception. Silicones are the organo metallic polymers derived from the abundant raw material on earth, sand. Silicone is a generic term that refers to a class of manmade polymers based on a frame work of alternating silicon and oxygen (Siloxane Bonds) with organic substituents attached to the silicon [5]. Methyl groups are the most important organic substituents used in the commercial silicones. The Vast majority of which are Poly dimethyl Siloxanes.
