What Is D59 FR Fabric?
D59 FR fabric is a 100% cotton flame-retardant workwear fabric with a 4/1 satin / sateen weave structure. It is widely recognized in the South African industrial workwear market and is commonly used for mining uniforms, welding garments, maintenance workwear and protective clothing.
Compared with ordinary twill fabric, D59 fabric has a smoother satin surface. This helps reduce the chance of sparks, dust, metal particles or industrial residues staying on the fabric surface during daily work.
SAFE-GUARD D59 FR fabric is developed with 100% cotton, durable flame-retardant finishing and a regular production weight of 305g/m² ±5%. It is designed for protective workwear projects that require cotton comfort, flame-retardant performance and stable fabric structure.
D59 fabric in the market is not limited to one fixed GSM. Different D59 fabric references may appear around 270–340GSM depending on fabric type, finishing function and garment application. SAFE-GUARD’s current D59 FR fabric specification is 305g/m² ±5% according to our technical data.

Satin Weave Design for Smoother Workwear Protection
D59 FR fabric uses a 4/1 satin / sateen weave structure. This is an important feature of D59-style workwear fabric.
Compared with regular twill fabric, satin weave has a smoother surface. This smooth surface helps reduce the chance of sparks, dust, metal particles or work residues staying on the fabric surface during welding, mining, smelting, maintenance or other industrial work.
For protective workwear, this smoother surface can help improve garment cleanliness and reduce surface retention in harsh working environments. It also gives the fabric a more refined hand feel and appearance compared with rougher weave structures.
The smoother surface does not replace flame-retardant performance, but it supports better surface behavior for industrial workwear. Final protection still depends on fabric weight, FR finishing, garment design and testing requirements.
The satin / sateen weave structure can also support good tear performance because the yarns have more movement space than in tighter weave structures. However, final tear strength depends on yarn count, fabric density, GSM, finishing process and testing method, so fabric performance should be confirmed by actual test data.
Special note: D59 FR fabric should not be described as ordinary twill fabric. Its key structure is 100% cotton 4/1 satin / sateen weave with durable flame-retardant finishing.
Standards and Testing Direction
SAFE-GUARD D59 FR fabric can support the following testing directions according to the current technical data.
| Standard | Classification | Protection Direction |
| EN ISO 11611:2015 | Class 1 | Clothing for welding and allied processes |
| EN ISO 11612:2015 | A1/A2/B1/C1/E3/F1 | Protection against heat and flame |
| EN 61482-1-2:2008 | Class 1 | Protection against electric arcs |
South African D59 Fabric Reference
D59 fabric is widely recognized in the South African workwear market. Some D59 fabric and garment references are connected with SANS-related requirements. These standards should be presented carefully according to the actual testing and certification status.
| Standard / Reference | What It Relates To | How to Present It |
| SANS 1387-4 Type D59 | D59 cotton drill / satin fabric structure and physical fabric reference | South African D59 workwear fabric reference |
| SANS 1423-1 | Low-flammability textile fabric testing | Can be discussed if South African flame-retardant testing is required |
| EN 1149 | Anti-static protective clothing direction | Suitable for anti-static D59 FR fabric projects |
SANS / SABS testing requirements can be discussed according to project needs. Before official certification is issued, the product page should avoid wording such as “SABS Certified” or “SABS Approved.”
Garment Standard Note: SANS 434
SANS 434 is mainly a garment cut, make and trim standard for two-piece workwear suits. It is not a standalone fabric standard.
D59 fabric can be supplied for garment projects where the final workwear is designed according to SANS 434 requirements. However, the fabric itself should be presented based on its own fabric specification, finishing function and test data.
Applications
D59 FR fabric is suitable for industrial workwear projects that require cotton comfort, FR protection and stable fabric structure.
| Application | Recommended D59 Option | Why It Fits |
| Mining Workwear | Standard D59 FR Fabric | 100% cotton satin FR fabric for durable industrial uniforms |
| Welding Garments | Standard D59 FR Fabric | Smooth satin surface and FR finish for welding-related workwear |
