Materials of long johns on the market There are so many varieties
It’s easy to be confused.
Which one is right for you?
Pure cotton
Cotton fiber is a porous material whose main component is cellulose. It has good air permeability and is the first choice of many people.
Some people worry that after sweating, their long johns will become damp and uncomfortable on the skin, and may also cause skin diseases such as rashes. At this time, you can choose long johns made of pure cotton.
Artificial cotton
Artificial cotton is the common name for cotton-type short fibers. Generally, the basic composition of artificial cotton is cellulose, which is made by dissolving cellulose in a solvent. The fiber is ejected from a very fine nozzle to form filaments, similar to spider silk, sometimes called viscose fibers.
It has good hygroscopicity and smoothness, and is a common fabric for making long johns.
Modal
Modal, also known as Monel, Modal, etc., is a cellulose fiber like artificial cotton and is a man-made fiber.
It has good comfort, excellent hygroscopicity, and good drape, but its fabric has poor stiffness. Generally used in underwear products such as long johns.
Lycra
Lycra fabric is actually a type of spandex. “Lycra” is the transliteration of the English word “LYCRA”.
It further optimizes the performance of spandex, improves the elasticity and extensibility of the fabric, and has less binding force on the human body. And it can be used with any fabric and is called a “friendly” fiber.
Polyester fiber
Polyester fiber is actually polyester. Its advantages are good wrinkle resistance and shape retention, and high strength and elastic recovery capabilities.
Autumn and winter are relatively dry seasons, and static electricity is easily generated when wearing these autumn pants. It is best to apply some moisturizer before wearing them. Some people with skin prone to dryness, itching or allergies, as well as children with delicate skin, should try to avoid wearing this fabric.
Cashmere
Autumn pants containing cashmere have the highest thermal insulation index and are very popular among middle-aged and elderly people. But be aware that people who are allergic to wool are not suitable to wear long johns containing cashmere ingredients.
Bamboo fiber
Bamboo fiber is cellulose fiber extracted from bamboo, also known as bamboo fiber. Its chemical composition is mainly cellulose, semi- Cellulose and lignin.
Bamboo fiber fabric has good breathability, instant water absorption, strong abrasion resistance and good dyeability. It has natural antibacterial, antibacterial, mite removal, deodorant and UV resistance functions.
Spandex
Spandex is the abbreviation of polyurethane fiber and is a kind of elastic fiber. Spandex fiber, elastic polyolefin fiber and elastic composite fiber are collectively called elastic fiber.
Spandex has good elasticity, but poor strength and moisture absorption. It has good light resistance, acid resistance, alkali resistance and wear resistance. It is often added as a blended material to long johns fabrics to increase elasticity.
Wearing long johns that are too tight will cause blood circulation to stagnate. Not only will the body not be able to warm up, but it will instead become colder. It is recommended to choose loose and elastic ones.
Some groups of people need to wear long johns in advance, including women during menstruation and pregnancy, the elderly, patients with arthritis, and people with Yang deficiency.
