Crease recovery is defined as the property of fabrics, which enables the textiles to recover from the folding deformations. This is one of the essential properties expected to be there in most of the fabrics to make it easier to take care of these.
Cotton is one of the most common and comfortable fabrics in the stores of the fabrics wholesalers in Kolkata. Cotton fabric has numerous advantages. It is considered as one of the most comfortable fabrics sold by the fabric retailers in Kolkata and wholesalers. Creasing or getting wrinkles on fabrics, especially after washing, is one of the major issues in cotton because of free hydroxyl groups in the structure. When this type of fabric acquires creases, the molecular chains in amorphous zone slip past one another, thus, breaking the weaker hydrogen bonds. Then the new hydrogen bonds are formed in those stretched regions and then the fabric gets the creases. These wrinkles effect the appearance of the textile. This is the reason why cotton is treated with some chemicals for improving the wrinkle or crease recovery property.
What Is the Effect of the Softening Agents?
A softening agent gives an attractive and a smooth appeal to the garments and is considered as the most essential textile chemicals. These can make the textiles pliant, supple, fluffy, smooth, sleek, easier to drape, and more flexible.
Different Types of Softeners:-
- Anionic softeners like sulphated alcohols, sulphated oils, soaps, and oil emulsions.
- Non-ionic softeners like polyethylene emulsion, polyoxyethylene derivatives, and v.
- Cationic softeners like quaternary ammonium, and the other cationic products.
What Is the Effect of the Anionic Softeners on the Crease Recovery Property of Cotton?
In the thicker varieties of cotton fabric, this property of crease recovery increases considerably on the application of minimum two percent concentration of any ionic softeners. On increasing this concentration up to four percent or six percent, the crease recovery decreases.
In the medium cotton fabrics, the angle of crease recovery reduced on application of two percent concentration but it increases on application of four percent concentration of the softener. And again it decreases if increased to six percent concentration of the softener.
In case of the cotton fabric, be it of any thickness, the crease recovery angle either increases or decreases according to the concentration of the anionic softeners.
What Is the Effect of the Cationic Softeners?
Crease recovery angle of the thicker cotton fabrics increases on application of the cationic softeners of two percent concentration. But, on increasing the concentration of the softener to around four percent, the angle decreases but can be decreased even more on increasing the concentration of the softener to six percent.
In case of the medium weight cotton textiles, crease recovery is similar to the application of the anionic softeners on the finer cotton varieties. This has shown that the crease recovery angle decreases continuously on increasing the concentration of the cationic softeners. In case of the cationic softeners, the crease recovery angle decreases continuously on increasing the softener’s concentration to four percent. On increasing the concentration further, a slight increase in the angle of crease recovery can be noticed.
