Pilling
Pilling is a phenomenon in which surface fuzz on a textile becomes tangled through friction from wear or washing, remaining as spherical pills.

Definition and Overview
Pilling is the phenomenon in which fibers protruding from the surface of a textile become tangled through friction and turn into pills. When the pills do not completely come off the textile and remain on the surface, the appearance is impaired. It occurs not only in knits and brushed materials, but also in woven and knitted fabrics made with short fibers.
The extent of occurrence is not determined by fiber type alone. It is influenced by a combination of factors such as yarn structure, twist, knitting or weaving density, surface finishing, and friction conditions during wear. Even with the same material name, the likelihood of pilling differs depending on the textile design.
Conditions and Characteristics Where It Occurs Easily
It tends to occur in areas that are repeatedly rubbed, such as under the arms, under the sleeves, elbows, and places where a bag makes contact. During washing, friction between garments and against the washing tub is also a factor. Fuzzing may appear first, and then the fibers may entangle and the pills become noticeable.
In general, fibers with high strength that are difficult to break may keep the entangled fuzz from separating from the textile, making pills more likely to remain. On the other hand, because fiber length, blend ratio, yarn twist, and the amount of surface fuzz also affect it, fiber performance alone cannot be used to judge suitability.
Points for Material Selection and Product Design
For products where you want to suppress pilling, consider yarns with less fuzz, yarns with appropriate twist, and textiles whose surfaces do not fuzz excessively. Depending on the application, it is also effective to select textiles for areas subject to concentrated friction, design changes or reinforcement, and adjust ease allowance.
When selecting a textile, check not only the fiber composition label but also the actual surface of the textile, whether it is brushed, the knitting or weaving density, and the intended wearing situation. Before mass production, confirm wear performance and washing performance through prototypes, and determine whether the change in appearance is acceptable for the intended product concept.
- For everyday wear, check friction-prone areas such as under the arms, under the sleeves, and around the hips.
- Also assume rubbing from bags, seat belts, and layering.
- Evaluate brushed items and knitted fabrics with a soft, voluminous texture, including surface changes.
Care and Quality Control Notes
For washing, turn garments inside out, place them in a laundry net, and reduce friction. Do not overload the wash, and choose the washing method according to the care label. If pills form, keep the textile flat and carefully remove them with a pill remover or small scissors. Pulling them out may damage the textile.
Pilling is different from a textile defect; it is a change in appearance that can occur through friction during use. However, at the planning stage, it is important to confirm durability appropriate for the product application. Evaluation methods and judgment criteria vary depending on the customer, application, and test conditions, so they should be shared in advance.
Differences from Similar Terms
Fuzzing refers to the state in which the ends of fibers protrude from the textile surface, making the surface look fuzzy. Pilling is the state in which that fuzz and similar fibers become tangled into spherical pills. Fuzzing may be seen as a preliminary stage of pilling, but the two do not mean the same thing.
Snagging is a phenomenon in which yarns or loops are pulled out by catching on something. While pilling is mainly pills caused by friction, snagging is mainly caused by catching on projections or similar objects. Because the causes of appearance defects and the countermeasures differ, confirm them separately.
Frequently Asked Questions
What materials are prone to pilling?
Pilling is not a phenomenon that occurs only with specific materials; it occurs depending on factors such as short-fiber fuzz, yarn twist, knitting or weaving density, whether the surface is brushed, and friction conditions. In general, pills become more noticeable when tangled fibers do not break and remain on the surface. It is important to check evaluation by textile, not just the material name.
Is it okay to remove existing pills?
It is common to gently remove them little by little with a pill remover or small scissors after smoothing the surface. Pulling forcefully or picking them off by hand may lead to broken yarns, holes, or surface damage. In particular, thin fabrics, brushed items, and fabrics with loops should be tested in an inconspicuous area first.
Is there anything I can do at home to prevent pilling?
Turning garments inside out, placing them in a laundry net, and washing them separately from garments that cause strong friction can help suppress pilling. It is also important not to overload the wash. During wear, avoid continuous rubbing at the same spot from bags or layering, and care for fuzz early before it develops further.
