How it differs from conventional recycling
[Conventional]
・Clothing → wiping cloths (industrial rags)
・Clothing → insulation material
・Plastic bottles → fiber
[T2T (Textile to Textile)]
・Clothing → fiber → yarn → textile → clothing
・Textile waste → yarn → textile → clothing
In other words, T2T is a circular recycling approach aimed at "making clothing from clothing."
In recent years, with the EU placing a strong focus on sustainability, the promotion of a circular economy has progressed, and attention has been growing in the apparel industry toward materials that support T2T. These are sustainable products that can be confidently recommended even to brands that promote the ethical theme of "wanting to use environmentally friendly materials."
What is the closed-loop process?
Often discussed alongside T2T is the
closed loop
process.
A closed loop refers to a circular system in which
products are collected and reused as raw materials for the same product.
For example, in apparel, the cycle of "clothing
→ collection → recycled fiber → yarn → textile → clothing" is repeated.
*In contrast, a system in which materials are recycled once and then diverted to another use is called an open loop.
Going forward, not only reducing environmental impact but also from the perspective of effective use of resources, the development of closed-loop materials is expected to advance further.

RE:NEWOOL
RE:NEWOOL is a recycled wool series made by reusing collected wool products and leftover rolls.
It gives new value to wool materials while making effective use of resources that were previously discarded.
It is ideal for sustainable proposals for autumn/winter items such as coats, jackets, and pants. The unique heathered texture and appearance of wool are also part of the fabric's appeal.

UNITO®
Textile waste such as undyed fabric and yarn waste generated during production is collected, reborn as new yarn, and then transformed into textiles using that recycled yarn.
While many common recycled materials are made with 30% or more recycled raw material, UNITO® uses its unique production network to carefully collect only high-quality textile waste. This achieves a high recycling rate with 100% recycled yarn. It also has the subtle irregularity and rough texture unique to recycled cotton, giving it an attractive vintage-like, natural feel.

View productA pique material with substantial thickness. It has a volume of 335gsm, yet the irregular surface typical of pique gives it good separation from the skin. Not only for standard polo shirt applications, but also for casual wear such as polo dresses that can be worn on their own, since the knit has a moderate firmness and presence and is not prone to showing through.

SEACELL®
SEACELL® is a sustainable
regenerated fiber made from seaweed, developed by the German company Smartfiber.
It uses seaweed grown in Icelandic fjords and cellulose as raw materials, and is attracting attention as an environmentally considerate material that utilizes renewable natural resources.
Its manufacturing process uses a closed-loop method that collects and reuses the chemicals used. By producing while circulating resources, it reduces waste and environmental impact.
Traceability is also ensured from raw material procurement through production.
In addition, SEACELL® is a 100% biodegradable and compostable material of natural origin, designed with consideration for the natural environment even after use.

This is an environmentally and human-friendly sustainable material that realizes circular manufacturing through the use of renewable resources and a closed-loop process.
Summary
T2T (Textile to Textile) is a circular recycling concept in which used clothing and textile waste are reused as fiber.
As the need to address the circular economy grows worldwide, including in the EU, the importance of choosing materials that are easy to recycle and environmentally friendly materials is likely to continue increasing.
At ApparelX, we carry many fabrics, accessories, and supplementary materials that are useful for sustainable manufacturing, including the SEACELL®, RE:NEWOOL®, and F EARTH® introduced here.
For the future of the apparel industry, we would be happy if you would first consider incorporating sustainable elements starting with material selection.
