The main components of socks are: natural fibers-cotton and bamboo fiber; Synthetic fibers-synthetic fibers such as polyester and elastic fibers such as spandex;
Comparison of fiber wear resistance: bamboo fiber
In the process of wearing socks, natural fibers (cotton fibers or bamboo fibers) that are not wear-resistant are worn off first, and synthetic fibers have good wear resistance and are not easy to break. Such worn natural fibers are wound around synthetic fibers to form small balls, which is pilling.
If the socks are completely synthetic fibers, there will be no fiber breakage and pilling, but they will not absorb sweat and easily stink their feet;
If socks are all natural fibers, they will not pilling, the fibers will wear out and pilling will not occur. They will be drenched in sweat, and their feet will not stink, but they are inflexible, durable and costly.
Therefore, the main reason why we usually ask for pilling is that the composition ratio is reasonable. Generally, when the natural fiber content is above 80%, the pilling resistance is very good, and at the same time, it is soaked and sweaty, and the feet feel very good!
Good socks should be made of fine cotton yarn, which is soft to the touch. Of course, cotton fiber or bamboo fiber with high content is better! The elastic fiber spandex should be more than 5%, which has good elasticity and polyester is more wear-resistant. If you breathe first, it would be nice to have a high content of natural fiber now!

Extended data
(1) fuzzing: the fiber ends are pulled out of the fabric due to friction, resulting in fuzzing; The monofilament in the filament breaks and is hooked out to form a ring.
(2) Pilling: The fibers that have not fallen off are intertwined, and the more they are intertwined, the tighter they are, and finally a small ball is formed.
(3) Falling off: When the fabric continues to rub, the fibers connecting the wool balls will break due to repeated stretching and bending fatigue and fall off the fabric surface.
Experience shows that any short fiber will pilling, polyester short fiber, wool and cotton fabric pilling is more serious. There are many factors that affect pilling, but they can be summed up in four aspects: yarn, fabric structure, dyeing and finishing process and wearing conditions.
Yarn of (1) fabric
All kinds of fibers, yarns and fabrics will have pilling phenomenon. Because the length and fineness of fiber, low twist, fluffy yarn, single yarn, weaving type and finishing agent used will all promote fiber pilling. For yarns with large twist and compact structure, the internal fibers are not easy to be pulled out and pilling is not easy.
(2) Fabric weave structure
Fabric with loose structure is easier to pilling than fabric with tight structure, so the knitting method of socks may also affect the pilling of socks. Compared with clothing, the knitting method of socks is relatively simple, so pilling is more common than clothing, but relatively speaking, the pilling probability of flat knitted fabrics is much smaller than that of rib fabrics. At least 168 hosiery machine should be used for Aimu spinning wood fiber socks, which has smooth surface and is not easy to pilling.
(3) the influence of dyeing and finishing process
After dyeing and finishing, the pilling resistance of yarn or fabric will change greatly, which is related to dyes, auxiliaries and dyeing and finishing conditions. Fabric dyed with shirt is easier to pilling than fabric dyed with yarn. The dyeing process of Aimu spinning wood fiber socks adopts environmentally-friendly reactive dyeing technology, and all links are strictly controlled. The yarn is dyed first and then the socks are woven, so that the featherless yarn maintains its original quality, has no broken hairiness and is not easy to pilling.
(4) Wearing conditions
Generally speaking, when a fabric is worn, the greater the friction, the more times of friction and the more serious the pilling phenomenon. Under normal circumstances, the lining material of your shoes is too rough, which increases the friction to socks. Insoles made of different materials have different degrees of friction to socks, and the way of washing socks will also cause socks to pilling. For example, throwing socks into the washing machine and washing them with other clothes will aggravate friction and eventually cause pilling, but it has no effect on wearing and wear resistance.
