From a laundry in Bayrampaşa to a garment group producing for Europe — and from 2026, a facility in Port Said.
Brothers Bahri and Necmettin Yılmaz establish the Yılmaz Laundry Factory in Bayrampaşa, washing linen for hotels, hospitals and restaurants.
The plant moves to Gaziosmanpaşa to serve under better conditions. The partners are Bahri, Burhan and Ali Haydar Yılmaz.
Ahmet Feyruz Yılmaz completes his education and joins the partnership in place of Bahri Yılmaz.
As garment exports rise, textile washing gains importance — with Yılmaz Laundry leading the way. The first customer is Güneş Giyim.
AKFIL produces indigo jeans in Türkiye for the first time and blue-jean washing begins.
The first work on piece dyeing is carried out and the bleaching method is introduced in denim washing.
YILMAZ Textile Washing and Dyeing is founded, running washing and dyeing together with fifteen 60 kg machines and three dryers, and hires its first chemical engineer.
The land of today's Güneşli factory is purchased. A second washing plant opens in Gaziosmanpaşa under the name YILTEKS, and the laundry business is left behind entirely.
YILTEKS moves onto the Güneşli site. Larger drums replace classic washing vessels, making YILTEKS a pioneer in the sector; work with exporting companies intensifies.
The two companies merge under the YILTEKS name, taking an important place in the market with technological development and experienced chemical engineers.
Three shifts run with 170 workers, and YILTEKS begins manufacturing machinery suited to its own operating conditions.
The old machinery park is completely replaced.
The foundation of a new facility is laid in Çorlu, and YILTEKS Garment is founded.
The Güneşli factory works with 300 staff on 10,000 m², reaching 60,000 pieces a day in washing and 10 tonnes a day in dyeing, with its own R&D laboratory.
The Çorlu facilities open. YILTEKS Garment produces 50,000 blue jeans a month for export to Europe.
Yılmak Machinery is founded to design and produce the washing and dyeing units the textile and garment sectors need.
A barcoded production-tracking system is introduced to improve customer satisfaction and production follow-up.
YILTEM Garment is founded and quickly reaches a monthly capacity of 250,000 pieces, growing from small-volume orders.
Organic washing certification is obtained and vegetable-dyeing processes begin.
YILSU Machinery is added so that growing water demand can be stored healthily and hygienically.
The information infrastructure is rebuilt and business processes are united in a single SAP ERP system.
The group enters the insulation and energy-saving sector through YILSU Machinery.
The Düzce facilities open; YILTEM completes its planning to raise monthly capacity from 150,000 to 250,000 blue jeans.
Yılteks Textile Solutions LLC starts operations in the Port Said Public Free Zone — 300,000–400,000 pieces a month in denim and non-denim garments.
