How Do I Care For My Acrylic Yarn?

Since sweating is inevitable from wearing an acrylic fabric or garment, it is best to have a proper way of caring for your wears to get rid of sweat and body odors to give them a fresh look and pleasant scents.

Before you decide what method to wash, it is best required that you check the fabric care label well and follow the instructional cleaning method and guide to know if it is hand-washable, machine-washable, or can be ironed. However, delicate and flexible items should be hand-washed and laid flat to dry to prevent them from stretching beyond their original shape or length. 

1. To Hand-Wash Acrylic Fabric

Use a mild laundry detergent, soap, or liquid wash that is specified for flexible and delicate clothes. Then pre-soak the clothing items for about 20 to 30 minutes before you wash them normally. After, warm or cold rinse them but do not use hot water as this can cause the fabric to stretch. 

2. To Machine-Wash Acrylic Fabric

The first thing is to pretreat the stains. This is done by spraying the stained spot with fabric stain remover. Then, scrub the spot lightly with a brush.

Then, load the washing machine: into the washer, put the clothes, and add an all-purpose of your favorite laundry detergent for acrylic fabrics and also your choice of fabric softener to the final rinse this is because acrylic fabrics tend to hold excessive static, the softener helps to eliminate all. 

Lastly, wash the load: The wash cycle selected should be a permanent press and not washed with hot water. If the final cycle of the washing machine is a high spin rate, it is best to set it to a low spin rate. 

3. To Dry The Clothes

Dry the washed clothes by hanging them, laying them flat to dry, or tumble drying them on low heat in the machine. Avoid drying in high heat as this tends to cause the fabric to stretch, wrinkle or damage. It is best to, however, hang dry acrylic clothing when they’re still wet. 

4. Ironing The Clothes

However, if the clothes require ironing, iron at a low temperature using steam and a press cloth to prevent the iron from melting or burning the fabric and also protect it from getting shiny marks as this situation is irreversible.
