What is Mercerization process? Mercerization is a process in which textiles (typical- ly cotton) are treated with a caustic (NaOH) solution to improve properties such as fiber strength, shrink- age resistance, luster, and dye affinity. The caustic actually rearranges the cellulose molecules in the fiber to produce these changes.

Which dyes are used for cotton?
Indigo is the original vat dye. Vat dyes are the fastest dyes for fabrics like cotton, linen and rayon. Used with a mordant they are also used to dye other fabrics such as wool, nylon, polyesters, acrylics etc. Reactive dyes react with fiber molecules to form a chemical compound.
What temperature is HTV on canvas?
With the heat press pre-heated to 360 degrees, press for 30-35 seconds and slowly peel away the backing sheet when the design is warm.
Why is my heat transfer vinyl not sticking?
Time- Pressing or ironing for too short a time can cause HTV not to stick to your shirt. … HTV works by using a heat activated adhesive so too little time and it won’t heat enough to stick. Too long and it can actually burn the adhesive off. Temperature- Not all vinyl applies at the same temperature.
What temperature do you press HTV on polyester?
You can put in the type of heat transfer vinyl you’re using, the material you’re putting your decal on, and whether you’re using a pressing pillow (I recommend using one!) or a towel. For a Polyester Bag it’s recommended you use these settings: Temperature: 315 degrees. Time: 30 seconds.

It is specifically designed for use on 100% cotton, 100% polyester, or 50/50 blends. … A basic everyday clothing iron will work just as well.
What are the main objectives of Mercerizing process?
Mercerizing is the process of treating cellulosic elements with cold or hot caustic conditions to improve their appearance and physical as well as chemical properties under certain conditions. In simple words, the process of treating caustic alkali under pressure for increasing color, strength, and luster.
What is finishing process in textile?
Textile finishing processes comprise washing, bleaching, dyeing and coating, as applied to bulk textiles or garments following weaving and/or production of synthetic materials. These are energy-intensive and use large amounts of water that is generally discharged as effluent.
