Driven by this vision, we developed J-TECH EASY CARE (formerly Known as PALPA Premium)—a special yarn made by wrapping cotton around recycled polyester.
After three years of development and seven years on the market, it has become our No.1 best-selling fabric, loved for its exceptional comfort and durability.
With only cotton touching your skin, it delivers the natural feel of cotton with a refined sheen.
Comfort, functionality, and sustainability—this proudly Japan-made shirt offers it all.
Experience the difference today.
※ As of January 2025, "PALPA" has been renamed "J-TECH EASY CARE".
Unlike conventional wrinkle-resistant fabrics that rely on surface coatings or resin treatments, J-TECH EASY CARE achieves the same effect through its unique yarn structure.
It has earned a 3.5 rating on the Wash & Wear scale, ensuring long-lasting easy-care performance even after repeated washing.
Quick-Drying
The outer cotton absorbs moisture, while the inner polyester speeds up drying—combining the best of both materials.
As a result, it dries three times faster than a 100% cotton shirt.
Even on humid days, during overnight washes, indoor drying, or when damp from sweat or rain, you’ll notice the difference.
Generally, a rating of 2.5 or higher is considered suitable for wearing straight out of the wash.
With a 3.5 rating, J-TECH EASY CARE delivers exceptional wrinkle resistance, making it an ideal choice for dress shirts that maintain a sharp, smooth look without extra effort.
Comparison with Standard Wrinkle-Resistant Shirts
Easy-care properties are added through chemical treatments or resin processing.
While labeled as 100% cotton, the fabric tends to feel stiff and has an unnatural texture.
Over time, with repeated washing, the wrinkle resistance diminishes, leading to a loss in its long-lasting performance.
While 100% polyester is easy-care and resistant to wrinkles, it tends to have a sporty look and is less suitable for dress shirts.
The fabric lacks the natural feel of cotton and may not provide the refined appearance expected in more formal attire.
Easy to maintain while retaining some of cotton’s texture.
However, since the polyester fibers are exposed, it has a slightly unnatural appearance and a firmer feel against the skin.
J-TECH Easy Care Yarn
With a polyester core wrapped in cotton, this unique structure offers a natural look and texture while maintaining its wrinkle resistance even after washing.
Traditional easy-care shirts often required compromises.
But with Kamakura Shirt’s easy-care shirt, you no longer have to sacrifice appearance or functionality.
Selected for METI’s "Manufacturing Supply Chain Reconstruction Support Project"
With its selection for the Ministry of Economy, Trade, and Industry (METI) initiative, Kamakura Shirts partnered with Unitika Tokiwa Factory in Okayama, known for its top-tier spinning technology in Japan.
After three years of development, this collaboration led to the creation of the world’s first J-TECH EASY CARE yarn, which was patented in 2019.
This innovative yarn features a recycled polyester core wrapped in cotton, combining Indian premium cotton with high-whiteness Australian luxury cotton in a unique blend, achieving both functionality and a refined look.
