What is meant by wet processing?
Wet-Processing is the processing stage at which textile substrate is treated with colourants and/or chemicals, collectively referred to as inputs in GOTS terminology. This includes sizing, desizing, pre-treatment, dyeing, printing (including digital printing), finishing, laundry, etc.
Which chemicals are used in wet processing?
Major Chemicals Used in Wet Processing: Acids, bases, salts, surfactants, oxidizing agents and reducing agents are the major chemicals those are widely used in wet processing industry.
How many types are there in textile wet processing?
The wet processing sector can be divided into three distinct sections. Preparation process or preparatory process. Coloration process. Finishing process.
Why is it called the wet process?
The processes of this stream are involved or carried out in an aqueous stage. Hence, it is called a wet process which usually covers pre-treatment, dyeing, printing, and finishing. All of these stages are required aqueous medium which is created by water.
What is textile engineering?
“Textile Engineering” is a big research field of technology that deals with all activities of producing textile fabric & yarns which are involved in the process of textile manufacturing. It includes process engineering that spins around the garment, color, and fabric line of industries.
Why wet processing is important?
Textile wet processing, which includes scouring, bleaching, coloration, and finishing in an aqueous medium, is of crucial importance for improving the performance and serviceability of textile materials. A massive amount of water, energy, and chemicals are required in the wet processing of textiles.
Why acid is used in wet process?
Acid: Acid is used to control PH. Acid decrease the pH of the solution. A test is carried out to measure the amount of peroxide present in the solution. Bleaching Agent: Bleaching is carried out before dyeing or printing operation.
Why Silk called the queen of fabrics?
Silk is known as the Queen of all textile fibres because of its sheen and luster. It is one of the most beautiful and precious fibres given to us by nature and has been very much overshadowed over the past few decades by the other natural fibres and more particularly by synthetics.
What is the difference between dyeing and printing?
Dyeing can produce only one color while printing can produce various types of colored design on the surface of knitted fabrics. Dyeing is done on grey fabric but printing can be done on both pre-treated fabric and colored fabric. For printing, dyes are applied on the fabric localizedly to produce desired design.
What is wet process of cement?
The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker. The slurry’s water content is usually between 32%-36%.
Is Textile Engineering a good career?
Textile is a growing industry and candidates interested in making a mark in the field of fashion, garments and Fibre manufacturing can go for Textile Engineering. This course offers a bright career for the students because the demand and supply of textiles will never diminish.
How do I become a textile engineer?
Tech in Textile Engineering course in India: The candidate must have passed Senior Secondary School from a recognized national or state level board. Compulsory subjects in 10+2 for admission are Physics, Mathematics and one of the subjects from Chemistry, Bio-Technology, Computer Science and Biology.
What does wet processing mean in textile engineering?
Wet Processing: The process is applied on textile in form of liquid with involves some for chemical action on the textile is called wet processing. Wet processing is one of the major streams in textile engineering refers to textile chemical processing.
Which is a stream of wet process engineering?
Wet process engineering is one of the major streams in textile engineering which refers to the engineering of textile chemical processes and associated applied science. The other three streams in textile engineering are yarn engineering, fabric engineering, and apparel engineering.
What are the three principle of wet processing?
In this process it have involving three principle process, that are retardation, migration and diffusion which all this are chemical process. There are many type of dyeing that using in textile wet processing such as cross dyeing, union dyeing and gel dyeing.
How is the wet process of manufacturing done?
The wet process is usually done in the manufactured assembly of interlacing fibers, filaments and yarns, having a substantial surface (planar) area in relation to its thickness, and adequate mechanical strength to give it a cohesive structure. In other words, the wet process is done on manufactured fiber, yarn and fabric.
