Merino Wool

Definition and Overview

Merino wool is an animal fiber obtained from Merino sheep. It is a type of wool in general, but it is characterized by relatively fine fibers and a soft feel against the skin. It is used in both woven and knitted fabrics, and its appearance and applications change greatly depending on yarn thickness and processing.

“Merino” is a material name derived from the sheep breed and does not indicate a weaving or knitting method. Also, even when labeled as merino wool, fiber fineness, blend ratio, spinning method, and finishing process differ by product.

Texture and Function

It is supple and resilient, and in worsted yarn it tends to create a smooth, elegant surface, while in woolen yarn it tends to create a fuller, warmer appearance. Materials made with fine fibers have a delicate look with reduced fuzz.

Wool has the property of absorbing and releasing moisture, and it is used as a material that helps regulate the clothing environment. In addition, the air layer created by the crimp of the fibers contributes to heat retention. The degree of functionality varies depending on the yarn, structure, industry weight, blend materials, and processing, so it is important not to judge by the material name alone.

Main Applications and Seasons

Lightweight merino wool is used for knits, cut-and-sew items, innerwear, shirts, cardigans, and more. Taking advantage of its soft feel and moisture absorption and release, it is also suitable for layered items.

From medium weight to heavyweight, it is used for sweaters, dresses, pants, jackets, suits, coats, and more. For spring and summer, finely count, thinly woven or knitted fabrics are generally chosen, while for autumn and winter, fabrics with fullness and a fuzzy feel are selected.

How to Choose and Handling Precautions

When selecting, check not only the merino wool label but also the blend ratio, industry weight, structure, thickness, stretch, care label, and shrinkage rate. For uses that touch the skin directly, feel the actual fabric to check for itchiness, and compare blended materials such as nylon or polyester according to the application.

Wool may shrink or felt depending on moisture, heat, and friction. Be sure to follow the care label for washing and ironing, and avoid vigorous rubbing, high-temperature drying, and excessive friction. Shaping while wet and drying flat makes it easier to prevent deformation.

Before sewing, carry out straightening and testing under the same assumed conditions as mass production, and check shrinkage and skew. Because knit fabrics stretch easily, it is necessary to consider sewing conditions that prevent stretching during sewing and methods to prevent stretching. To prevent shine and pressing marks from ironing, use a pressing cloth and appropriate temperature settings.

Differences from Similar Terms

Wool is a general term referring to all sheep wool, while merino wool is sheep wool derived from Merino sheep. On the other hand, lambswool generally refers to wool first shorn from a sheep after birth, and the classification basis differs from Merino, which indicates the sheep breed.

Cashmere, mohair, and alpaca are also animal fibers, but each comes from a different animal. Because texture, luster, pile length, strength, heat retention, and other characteristics differ, it is important to check not only the material name but also fabric swatches and quality test results when choosing among them.
