A wet processing technology which uses air in form of dispersion foam for the media of application is called foam finishing. The process consists of mechanically forming a suitable formulated finish or dye formulation and then applying the foam to textile fabrics. Collapse of the foam distributes the finish on the substrate. The fabric is […]
What is Resin finishing? Importance of Resin Finishing
Definition of Resin Synthetic resins are complex organic products of high molecular weight. Resin results when a number of simple molecular of low molecular weight become jointed together and to end to form much longer molecules which may be linear or linear molecules cross-linked. The main outlet of resins has been the plastic industry and […]
An Overview of Sizing, De-sizing, Scouring, Bleaching and Mercerizing
We know textile is a vast sector; it is not confined within a specific limit because it has limitless end-used items. Textile mainly deals fibres – maybe these are natural or synthetic. Whatever may be the fibres, it is well known, to all apart from its fibre stage to finishing stage (end-use stage), it involves […]
What is Fabric Pilling? Factors Responsible for Pilling
Definition of Pilling Pilling is a fabric surface fault characterized by little ‘pills’ of entangled fibre clinging to the cloth surface and giving the garment an unsightly appearance. It is bunches or balls of tangled fibres which are held to the surface of a fabric by one or more fibres. The pills are formed during […]
What is Textile Bleaching? Bleaching Process of Cotton
Definition of Bleaching A process of whitening fibres or fabrics or depriving a colored material. This is brought about by using various bleaching-agents. Generally chlorine is used for cotton and other vegetable fibres and peroxide and sulphur dioxide for animal fibres. Bleaching of Cotton Cotton is bleached in the raw state (as yarns) or in […]
Anti Static Finishes and its Application | Conductive Fibres
Introduction Static electricity can cause many processing problems for textile materials, especially those made form hydrophobic synthetic fibres. In most dry textile processes, fibres and fabrics move at high speeds over various surfaces which can generate electrostatic charging from frictional forces. This electrical charge can cause fibres and yarns to repel each other, leading to ballooning. Fabrics and non-woven are also affected […]
A Guide to Wool Carbonizing Process
The vegetable matter is removed by chemical means; the process is called wool carbonizing. The method is comparatively simple. The wool to be carbonized is placed in tanks containing solutions of some strong acid like chloride of aluminum, hydrochloride, or sulphuric acid. Here it remains for a period of twelve hours, during which it is […]
An Overview of Wool Scouring
Introduction The term “scouring” in the generic sense of a process that that removes contaminates from raw wool. Thus, it includes all processes which aim to clean wool including those which use solvent other than water and those which use solid as a carrier for removing the contaminates. Nature of Contaminates The main contaminates of […]
An Overview of Fabric Mercerizing
Definition This is a special treatment for cotton yarns, fabrics which improves the fabric luster and wet ability, ensures a covering effect for dead cotton, improves dimensional stability and dyeing efficiency. Mechanism This treatment is done by using caustic soda, which determines the contraction and swelling of the fibres; they become translucent their tensile strength, but reduce their flexural and torsion […]
Finishing Faults and Their Remedies
Finishing is the most import part in the Textile Industries because total quality of the dyed fabric depends on finishing. In this section fabric GSM, width, shrinkage etc. are controlled. But sometimes the subsequent faults are found after finishing. Wet Squeezer Marks Causes Remedies GSM Variation Causes Remedies Bowing Causes Remedies Skewing Causes Remedies You […]
