For buyers: three fibres carry most of the men’s market — pure cotton, modal and bamboo — and they differ in hand-feel, recovery and cost rather than in quality ranking. This page covers how each is best specified.

Xiamen Unitex Trade Co., Ltd. is a professional underwear sourcing & supply-chain management company based in Xiamen, Fujian Province, in the Xiamen–Quanzhou–Jinjiang knitwear cluster of south-east China. Founded by Will Lin, who has worked in the apparel trade since 2004, the company has been exporting since 2009 and was incorporated in Xiamen in 2013. It runs its own liaison office in Jinjiang and works with a network of BSCI & OEKO-TEX Standard 100 certified partner factories to serve retailers and brands across Europe, the US and Australia.

Most women are very particular about underwear. After all, good underwear can bring out a good figure and make you more attractive and charming. In fact, men’s underwear also needs to be cared for. After all, it is the most sensitive part of men. It is also learned to choose underwear. It is not only a pair of pants, but more importantly, it is related to your daily comfort and hygiene. In fact, it is closely related to your prostate health, so you must not be sloppy!

    

I think there are three things to keep in mind as Choosing men’s underwear is also very knowledgeable:

  1. Changing every two days is the bottom line
  2. Comfortable wearing is the foundation
  3. Dressing well is the pursuit

    

If you don’t even have the bottom line and foundation, and wear a poor quality underwear for a long time, then the consequences may be happened to yourself. Comfortable underwear has the characteristics of comfort, breathability, moisture absorption, etc., and the fabric is the key to underwear.

   

1. Pure cotton fabric:

The underwear of pure cotton fabric has strong hygroscopicity but weak moisture removal (not easy to dry). The skin is prone to redness, swelling, itching, rash or scrotal eczema, dermatitis, etc. when the skin is in contact with wet clothes for a long time. Therefore, if you want to wear cotton underwear, you should ensure the dryness of the underwear. People who are prone to sweating and men who drive frequently are not suitable for wearing underwear with high cotton content. At the same time, the elasticity of cotton is weak, and the fit of pure cotton underwear will be greatly affected (improper wearing can easily affect the normal development of adolescent reproductive organs), so cotton underwear should be added with 5%-10% spandex (top spandex such as DuPont’s “Lycra”) is used as an accessory to improve the elasticity of the underwear and enhance the fit. Unitex men’s underwear experts recommend that consumers with extremely sensitive skin and low sweating use combed cotton underwear with spandex.

2. Modal fabric:

“Modal” is actually the brand name of the fabric, which is a “regenerated cellulose” fiber. Regenerated cellulose fibers are softer, stronger and tougher than other fabrics, and have a significantly higher moisture-wicking ability than pure cotton products. Taking the most famous regenerated cellulose fiber brand “Lenzing Modal” as an example, its strength is much higher than that of pure cotton and polyester-cotton, so it is more personal to wear. In addition, the moisture absorption and perspiration capacity of modal is 50% higher than that of cotton fiber, which makes the fabric stay dry and breathable, which is beneficial to the physiological circulation and health of the human body. Modal is a pure natural fiber sourced from European bushes. Unitex men’s underwear experts recommend modal underwear for consumers who have strict requirements for underwear, especially comfort.

3. Bamboo fiber fabric:

This is a type of underwear fabric that has become more and more popular in recent years. The well-known bamboo fiber brands mainly include “Tianzhu Bamboo Fiber”. Many underwear brands at home and abroad, such as Unitex, have chosen Tianzhu bamboo fiber as the fabric for their main products. Tianzhu bamboo fiber is a pure natural fabric, the raw material is extracted from naturally grown bamboo. In addition to fiber fineness, dry strength index, and moisture absorption and perspiration ability higher than ordinary cotton fabrics, it also has natural antibacterial, antibacterial, mite removal, deodorant and anti-ultraviolet functions: “Bamboo Kun” contained in bamboo fiber is antibacterial. The substance has the effect of deodorization and deodorization on personal clothing, and has a particularly outstanding antibacterial ability. At the same time, bamboo fiber does not have any free charge, antistatic, and antipruritic, its color often affects the willingness to buy.

The printing of boxer pants is one of the driving forces for purchasing. The more high-end ones will use colored yarns, that is, each yarn is dyed first, and then the fabric is knitted. These yarn-dyed pants are the same color on the inside and outside. Unitex Men’s printed boxer briefs combine comfort and fashion.

Combining comfort and fashion, it is comprehensively applied to the fabric of underwear. This is full of vibrant flowers, which has a great visual impact, but it makes people feel very good-looking and individual.

  • Cotton fabric, strong texture with a little softness, durable and washable, even if you look back in three or five years, it still looks like the new one.
  • The 3.5 cm wide-brimmed waistband, with jacquard white letters and black belts, is distinctive and full of personality.
  • The crotch is loosely set, breathable without restraint, and there is enough room for movement.
  • The workmanship of the boxers leg hemming is skin-friendly, stretching enough, it doesn’t strangle the thighs and doesen’t curl.

   

The Unitex Men’s comfort breathable cotton boxer underwear is what you deserve.

Buyer checklist

  • Decide the fibre against the marketu2019s buying criterion rather than against a preference.
  • Specify the blend ratio to the percentage rather than naming a dominant fibre.
  • Fix the weight in g/m² per style — the same blend at two weights is two products.
  • Ask for the wash test on the actual blend rather than on the fibre in isolation.
  • Confirm the care instruction against the blend rather than the dominant fibre.
  • Check the certification route if an organic or sustainability claim is made.
  • Confirm the processing route for any fibre-level claim.
  • Check the hand-feel against the price tier you are selling into.
  • Compare two quotations on the specified figures rather than on the fibre name.
  • Approve on a production sample that has been worn and washed.

Buyer Questions

MOQ, lead times, certification and trading terms

Three fibres carry most of the market — pure cotton, modal and bamboo — and they differ in hand-feel, recovery and cost rather than in quality ranking. Which one suits a programme depends on the marketu2019s buying criterion, and most ranges carry more than one rather than choosing. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It is different rather than better. Modal gives a softer hand and better shape retention; cotton gives a drier feel and a lower cost at the same weight. In a comfort-positioned range modal usually justifies its premium; in a price-led basics pack it often does not. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

By ratio to the percentage plus the weight in g/m². Those two figures, with the knit structure, explain most of the difference between two garments that look the same. 95/5 and 90/10 behave differently in wear, which is why the ratio belongs in the tech pack. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It depends on the processing route, which is why the fibre name alone does not settle the question. Bamboo fibre is produced through more than one process, and the sustainability claim rests on which route was used and what certification supports it rather than on the plant it came from. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

They do, which matters for the care instruction. Cotton can move dimensionally, modal holds shape better but is less abrasion-resistant, and bamboo behaves differently again. A care label written for one fibre can be wrong for another, so the instruction follows the blend. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

By fibre, ratio and weight per style rather than by naming a fibre. Those three items are what makes two quotations comparable and what makes a claim about hand-feel or durability checkable against the sample rather than arguable.
