Condition Overview

Fiber allergy, also called textile dermatitis or fabric allergy, is a reaction to synthetic fibers like polyester, nylon, acrylic, or rayon. Some people also react to wool. The reaction can be to the fiber itself or chemicals used in processing. Symptoms include itching, rash, or hives where synthetic fabric contacts skin.

Common Clothing Triggers

These are fabric, finish, and construction factors that may worsen symptoms for some people.

Polyester

Most common trigger fiber in modern clothing

Nylon

Second most common synthetic allergen

Acrylic

Causes reactions in sensitive individuals

Rayon/Viscose

Processing chemicals can trigger responses

Spandex/Elastane/Lycra

Elastic fibers cause contact dermatitis

Wool

Natural fiber that irritates some people

Synthetic fabric blends

Even small percentages can cause reactions

Polyester thread in seams

Hidden synthetic in "100% cotton" labels

Frequently Asked Questions

Yes! We use cotton thread throughout. Many "100% cotton" products use polyester thread, which can cause reactions

|We don't use elastic. Our products use drawstring waistbands to avoid all synthetic materials

Symptoms include itching, rash, or hives where synthetic fabric contacts skin. A dermatologist can do patch testing to confirm

Washing may reduce some finishes but won't change the fiber itself. If you react to the synthetic fiber, washing won't help.

Yes, fiber sensitivities can develop at any age, often after repeated exposure or during hormonal changes

Unfortunately, cotton is our base material. For cotton allergies, silk or bamboo might be alternatives (consult your doctor)

Most organic cotton still uses polyester thread and synthetic elastic. Cottonique uses cotton thread and drawstring designs—no synthetics anywhere

Start by eliminating the most common triggers (polyester, nylon). Keep a symptom diary noting which fabrics you wore when reactions occurred.

Care Tips

Small routine changes can reduce exposure to irritants and residues.

Check all labels carefully

Even products labeled "100% cotton" may have polyester thread or synthetic elastic bands

Avoid "moisture-wicking" fabrics

These are almost always synthetic fibers (polyester, nylon) that trigger reactions

Watch for hidden synthetics

Many garments use polyester thread even when fabric is cotton

Pre-wash new garments

Wash new pure cotton items before wearing to remove any processing residue

Choose loose-fitting designs

Tight synthetic fabrics trap heat and moisture, worsening reactions

Keep a clothing diary

Track which items cause symptoms to identify your specific triggers

Avoid fabric softeners

These often contain synthetic chemicals that can irritate sensitive skin|Fewer seams mean less polyester thread contact with skin

Consider seamless options
