Acrylic fabric deserves gentle care to maintain its wool-like softness and durability. Whether you’re cleaning a cozy sweater or a lightweight blanket, understanding the proper washing techniques prevents damage while extending the lifespan of your garments. The synthetic fibers in acrylic clothing respond differently than natural materials, requiring specific temperature settings and handling methods to avoid common pitfalls like shrinkage, pilling, and static buildup.
Understanding Acrylic Fabric Before You Wash
Acrylic is a synthetic fiber that mimics wool’s warmth and texture while offering distinct advantages. Created from petroleum-based materials, this fabric provides excellent insulation and moisture-wicking properties without the hefty price tag of natural wool. The material remains wrinkle-resistant and holds vibrant colors remarkably well, making it a popular choice for sweaters, blankets, and cold-weather accessories.
Why Acrylic Needs Special Care
The molecular structure of acrylic fibers makes them sensitive to excessive heat and aggressive washing methods. Unlike cotton that tolerates high temperatures, acrylic can shrink, warp, or even melt when exposed to hot water or intense dryer heat. The smooth synthetic surface also attracts static electricity and develops surface pills from friction during normal wear and washing.
Preparing Your Acrylic Items for Washing
Read the Care Label First
Every garment tells its own story through the care label stitched inside. Check these instructions before proceeding, as fiber blends may require adjusted methods. Sort your light-colored acrylic items separately from dark fabrics to prevent unwanted color transfer during the wash cycle.
Pre-Treat Stains Immediately
Address stains before they set by applying a laundry pre-treatment solution directly to affected areas. Allow the treatment to penetrate for several minutes, giving it time to break down oils and dirt. This proactive step prevents the need for aggressive scrubbing that damages delicate acrylic fibers.
Turn Garments Inside Out
Flipping acrylic clothing inside out creates a protective barrier against friction. This simple action reduces pilling formation and preserves the outer surface’s appearance through countless wash cycles. Place items in a mesh laundry bag for additional protection against snagging and stretching.
Machine Washing Acrylic: Step-by-Step Method
Choose the Right Settings
Select your machine’s delicate cycle or gentle program, which uses slower agitation to protect fragile fibers. Set the water temperature to a maximum of 30°C (86°F), though cool water works even better for preventing damage. The reduced movement minimizes friction that causes surface deterioration over time.
| Setting | Recommended Option | Why It Matters |
|---|---|---|
| Cycle | Delicate/Gentle | Slower agitation prevents fiber damage |
| Temperature | Maximum 30°C (86°F) | Prevents shrinkage and warping |
| Spin Speed | Lowest setting (≤400 rpm) | Reduces stress on synthetic fibers |
| Load Size | Light to moderate | Prevents excessive creasing |
Select the Right Detergent
Liquid detergents designed for delicate fabrics dissolve faster in cold water and rinse cleanly from synthetic fibers. Avoid harsh bleaching agents and chlorine bleach, which break down acrylic’s molecular structure and cause irreversible damage. A mild, color-safe formula preserves the vibrant hues that make acrylic garments appealing.
Add Fabric Softener Strategically
Pour fabric softener into the final rinse cycle to combat static electricity that plagues synthetic materials. This addition softens the fabric texture and prevents that annoying cling when you wear the garment later. Use this treatment every third or fourth wash to maintain optimal softness without buildup.
Don’t Overload the Drum
Give your acrylic items space to move freely during the wash cycle. Overcrowding creates excessive friction between garments and produces stubborn creases that resist removal. A moderately filled drum allows water and detergent to circulate properly, ensuring thorough cleaning without compromising fabric integrity.
Hand Washing Acrylic: The Gentlest Approach
Prepare Your Washing Basin
Fill a clean basin or sink with cool water at approximately 25-30°C (77-86°F). Add a small amount of mild detergent specifically formulated for delicate fabrics, then gently agitate the water to create light suds. This controlled environment gives you complete authority over the washing process from start to finish.
Soak and Clean Gently
Submerge your acrylic garment in the soapy water and allow it to soak for 15-20 minutes. Focus attention on high-wear areas like sleeves, cuffs, and collars by using gentle crumpling movements rather than aggressive rubbing. The fibers need persuasion, not punishment—forceful scrubbing creates pills and distorts the garment’s shape.
Rinse Thoroughly
Drain the soapy water and rinse the garment several times in fresh cold water until all detergent disappears. Incomplete rinsing leaves residue that attracts dirt and creates a stiff, uncomfortable texture. Consider adding anti-static conditioner to the final rinse for extra softness and to eliminate static cling.
Remove Excess Water Carefully
Never wring or twist acrylic fabric—this violent action stretches fibers and permanently distorts the garment’s shape. Instead, gently squeeze out excess water using light pressure with your hands. For best results, lay the damp garment flat on a clean terry cloth towel, roll them together, and press gently to absorb moisture.
Drying Acrylic: Preserve Shape and Texture
Air Drying: The Safest Method
Lay your acrylic garment flat on a clean, dry towel or drying rack positioned away from direct sunlight and heat sources. Reshape the item to its original dimensions while it’s still damp, smoothing out any wrinkles or distortions. This horizontal drying method prevents stretching from gravity that occurs when hanging wet knits.
Avoid the Tumble Dryer
Never use a tumble dryer for acrylic items, as the concentrated heat causes irreversible shrinkage and fiber damage. The tumbling motion also increases pilling formation and can melt synthetic fibers at high temperatures. If you absolutely must use a dryer, select the lowest heat setting and remove items while still slightly damp.
Machine Spinning: Proceed with Caution
When using a washing machine’s spin cycle, keep the speed at minimum settings (no more than 400 rpm). The garment should emerge slightly damp rather than soaking wet. Excessive spinning stresses the fibers and creates stubborn creases that refuse to relax even after drying completes.
Common Problems and Smart Solutions
| Issue | Cause | Prevention Strategy | Fix |
|---|---|---|---|
| Pilling | Friction from wear and washing on soft fibers | Wash inside out in mesh bag; use gentle cycle | Remove carefully with fabric shaver or stone |
| Static Buildup | Low humidity and synthetic fiber friction | Add fabric softener or anti-static spray | Use dryer sheets or refresh with water mist |
| Color Fading | Harsh detergents and excessive heat | Wash in cool water with color-safe detergent | Turn inside out; avoid hot water |
| Shrinkage | High temperature exposure during washing or drying | Never exceed 30°C water; skip tumble dryer | Prevention is key—shrinkage is often permanent |
| Odor Retention | Synthetic fibers trap oils and bacteria | Air out promptly after wearing | Use vinegar rinse or refresher spray |
Tackling Stubborn Pills
When pills appear despite preventive measures, lay the garment flat on a firm surface and apply light tension. Use a fabric shaver or sweater stone with short, controlled strokes moving in one direction. Clear collected debris regularly and finish with a fabric brush to reset the surface texture.
Managing Static Electricity
Static cling becomes particularly troublesome in dry winter months when humidity drops. Beyond fabric softener, try hanging garments in a steamy bathroom for a few minutes or lightly misting with water from a spray bottle. Anti-static spray provides immediate relief when you need to wear the item right away.
Ironing and Steaming Acrylic
Low heat remains the golden rule when pressing acrylic fabrics. Set your iron to the coolest temperature setting and always press the garment inside out to protect the outer surface from potential shine or scorch marks. A handheld steamer offers a gentler alternative that removes creases without direct contact, eliminating the risk of heat damage entirely.
Special Considerations for Acrylic Blends
Many garments combine acrylic with other fibers like wool, cotton, or polyester to enhance performance characteristics. Read care labels carefully, as these blends may require adjusted washing methods. When in doubt, follow the most delicate care instructions among the combined fibers—this conservative approach protects all components equally.
The Environmental Angle
While acrylic comes from petroleum-based sources, it ranks among the more environmentally friendly synthetic materials available. The manufacturing process emits less carbon dioxide compared to polyester production, and the fabric’s exceptional durability reduces waste by extending garment lifespan. Proper care maximizes these environmental benefits by postponing replacement purchases for years rather than months.

Frequently Asked Questions (FAQ)
Can acrylic fabric shrink in the wash?
Yes, acrylic clothing tends to shrink when exposed to high temperatures during washing or drying. Using water above 30°C or placing items in a hot tumble dryer causes the synthetic fibers to contract permanently. Always stick to cool water and air drying to maintain the garment’s original size.
What happens if you accidentally wash acrylic in hot water?
Hot water causes acrylic fibers to warp, shrink, or lose their shape. The damage often proves irreversible, as the heat alters the synthetic material’s molecular structure. If this occurs, you may notice the garment feels smaller, stiffer, or has developed an uneven texture that won’t return to normal.
How do you prevent pilling on acrylic sweaters?
Turn garments inside out before washing and place them in mesh laundry bags to reduce friction. Select the gentle cycle with low spin speed and avoid overloading the washing machine drum. When pills do form, remove them gently with a fabric shaver rather than picking at them with your fingers.
Can you put 100% acrylic in the dryer?
No, tumble drying acrylic items leads to shrinkage, excessive pilling, and potential fiber melting at high temperatures. If you must use a dryer, select the lowest heat setting and remove items while still slightly damp. However, air drying flat remains the safest and most recommended method.
Why does acrylic fabric get so staticky?
Synthetic fibers like acrylic generate static electricity through friction during wear and washing, especially in low-humidity environments. The smooth surface of acrylic creates ideal conditions for electrical charge buildup. Add fabric softener to rinse cycles or use anti-static spray to neutralize these charges effectively.
How often should you wash acrylic clothing?
Wash acrylic garments only when visibly soiled or after 3-4 wears to minimize unnecessary washing that accelerates pilling and wear. Between washes, air out items to remove odors and refresh the fabric. Overwashing synthetic materials shortens their lifespan and increases environmental impact through excessive water and energy use.
What’s the best detergent for washing acrylic fabrics?
Choose liquid detergents formulated for delicate or synthetic fabrics, as they dissolve quickly in cold water and rinse cleanly from fibers. Avoid products containing chlorine bleach or harsh chemicals that damage acrylic’s structure. Color-safe, mild formulas preserve the vibrant colors that make acrylic garments attractive while protecting fiber integrity.
