Teijin Frontier Develops Seamless Knitwear
Using Special Bulky Fancy Yarn
Providing Both Thermal Comfort and High Functionality
Tokyo, Japan, November 21, 2023 --- Teijin Frontier Co., Ltd., the Teijin Group’s fibers
and products converting company, today announced the development of Microft🄬 AR, aseamless knitwear for outdoor sports, featuring warmth that gently envelops andinnovative stress-free comfort combined with a high functionality. The innovative clothingis made of a bulky fancy yarn using Teijin Frontier’s newly-developed high-performancepolyester filament.
Microft🄬 AR uses highly crimped (*1) DELTAPEAK🄬 processed yarn as the core to createa high density loop structure to provide favorable raising and bulky heat-insulating
performance while preventing fibers from falling off. Also, Teijin Frontier’s proprietarypolyester filament is used for pile to provide various functionalities. Low gauge seamless
knitwear (*2) made of the fancy yarn enables Microft🄬 AR to offer unique sense of fit suchas stress-free and soft, lightweight, and warmth that gently envelops with wear
comfortability such as sweat-absorbency and quick-drying, high breathability Also, it canbe compactly foldable in small-size. Furthermore, Microft🄬 AR is an environmentallycompatible product as it is made of 100% recycled polyester and features limited
appearance changes after repeated washing and wearing, long-term use, and a reduced
amount of falling-off fibers that are degraded to microplastics.
(*1) Highly crimped fiber: Crimped fiber that offer high bulkiness, elasticity, and stretchability.
(*2) Low gauge: Knitting coarsely with thick yarn.

Environmentalresponse- Light, soft, and thermal comfort thanks to super bulky
raised structure of special bulky fancy yarn
- Stress-free wearing comfort due to no seams- Comfortable fit thanks to low gauge bulky knit structure andstretch- Excellent sweat-absorbent/quick-drying performance
thanks to non-brushed structure- Prevention of sweaty feeling through high breathability- Functional combination (e.g., antibacterial deodorant) byusing various special original yarns for pile

Other

- Compactly foldable small-size

Microplastic
countermeasure- Reduction of falling off of fibers during washing thanks to
special high-density fancy yarn structure

Recycling- Made of 100% recycled materials

Wearability- Capable of long-term use with little morphological changesuch as pilling (*4) even after wearing and washing(*4) Hairballs generated on the surface of clothes due to friction during
wearing

Recently, outdoor clothing and sportswear are required to have a premium look and feel,
further wear comfortability (high water-absorbent/quick-drying and stress-free properties),and eco-friendliness are desired in addition to excellent heat retaining property. Light andthermal fleece materials are popular, nevertheless, it has some issues such as poor sweatabsorbent and quick-drying functions, bulkiness and appearance change after washing
and wearing due to brushed fabrics. Teijin Frontier focused on the structure of chenilleyarn (*3) to assure heat retention and functionality without brushing. However, conventional
chenille yarns have been mainly used for fashionable clothing with the focus on textures
such as soft feeling and airy appearance, lacking the functionality required for outdoor
uses.
(*3) Chenille yarn: Fancy yarn consists of core threads, pile, etc. Knitwear created with chenille yarn isgenerally considered high-pile and good in touch.

Teijin Frontier will begin promoting Microft🄬 AR for the 2025 autumn and winter outdoor
clothing and sportswear collections, thereafter, expanding globally for functional clothes
such as casual wear and uniforms. It expects Microft🄬 AR sales to reach 100,000 pieces
during fiscal 2026.
