How is cotton treated?

Cotton can be altered by using chemical treatments or finishes. Mercerization, for instance, is the process of treating cotton yarns or fabrics with sodium hydroxide for increasing absorbency, lustre, softness, and strength. During mercerization, fibre swells and its cross-section becomes rounder.

How is cotton treated to become fabric?

AFTER THE COTTON LINT HAS BEEN SPUN INTO YARN IT IS THEN WOVEN OR KNITTED INTO FABRIC. Weaving is the oldest method of making yarn into fabric. Warp yarn runs up and down the loom. Weft yarn is then woven (or sewn) over and under the warps from side to side.

How is cotton processed?

Cotton is harvested, compressed and sent to gins where they separate the fibers from the seeds. The fibers are baled, purchased by mills then spun into thread. Approximately 3.6 million bales of cotton are processed by U.S. mills each year. From here, your clothing, money, baseballs, and more are made.

What happens to cotton after it is picked?

Once harvested, seed cotton must be removed from the harvester and stored before it is delivered to the gin. Seed cotton is removed from the harvester and placed in modules, relatively compact units of seed cotton. A cotton module, shaped like a giant bread loaf, can weigh up to 25,000 pounds.

What is the pre treatment of cotton fabric?

Mercerization: Pre-Treatment of Fabric before dyeing it is a special chemical pre-treatment on cotton fabric to improve the properties and performance of cotton fabric. The cotton fabric is treated under tension in the 20 % caustic soda solution which is called mercerization.

How is cotton treated before dyeing and printing?

The cotton fabric is treated under tension in the 20 % caustic soda solution which is called mercerization. Due to mercerization many properties of cotton fabric is improved, some of them are mentioned below: Increases absorbance power. Increases fabric luster. Increases fabric softness and handle property.

Why is it important to use cationic cotton?

Cationic cotton technology prepares the fabric to accept a greater variety of dyes and provides for greater flexibility in the color offerings. Unique designs can be achieved by altering the level of cationization (higher = deeper color) and creating fabrics using both cationized and conventional cotton in the same fabric.

How is cotton yarn used to make fabric?

This little known plugin reveals the answer. Mechanical looms leave cotton yarn into fabric. Once the harvest is complete, the cotton is made into bales to be stored until it is ready to be ginned.
