TR fabric is one of the most common suiting fabrics used in the Indian textile and apparel market. In most commercial usage, TR refers to a polyester-rayon or polyester-viscose blended fabric, commonly used for trousers, suits, uniforms, safari suits and formalwear.
The term TR is often expanded as Terry Rayon or Terylene Rayon in trade language. It is not always used as a strict scientific fibre name, but as a practical market term for a fabric that combines the durability of polyester with the softness and drape of rayon or viscose.
TR fabric is generally understood as a blended suiting fabric made from polyester and rayon or viscose. In older and trade-oriented terminology, the polyester component may be referred to as Terylene, while the rayon component may be referred to as rayon or viscose rayon.
This is why TR is often explained as Terylene Rayon or Terry Rayon. In the fabric market, the same or similar fabrics may also be called poly-viscose, PV suiting, polyester-viscose suiting, TR suiting or Terry Rayon suiting.

It is important to understand that TR is mainly a commercial fabric term. A fabric should not be judged only by the name TR; its actual quality depends on the blend ratio, yarn count, fabric construction, GSM, finishing, dyeing, shrinkage control and garment requirement.
The exact composition of TR fabric can vary from one mill to another. Many TR suitings are sold in polyester-viscose blend ratios such as 65:35, 70:30, 80:20 or 85:15, depending on the intended price point and performance requirement.
A higher polyester percentage usually improves strength, crease recovery, dimensional stability and durability. A higher viscose percentage usually improves softness, absorbency, drape and wearing comfort.
| Common Blend Ratio | Meaning | Likely Fabric Character |
|---|---|---|
| 65:35 | 65% polyester and 35% viscose | Softer handle, better drape and better comfort compared with higher-polyester blends. |
| 70:30 | 70% polyester and 30% viscose | Balanced commercial suiting quality with durability and acceptable comfort. |
| 80:20 | 80% polyester and 20% viscose | More durable and crease-resistant, but may feel more synthetic. |
| 85:15 | 85% polyester and 15% viscose | Often economical and durable, but comfort depends strongly on finishing and fabric construction. |
The logic of TR fabric lies in blending two fibres with different strengths. Polyester gives the fabric durability, wrinkle resistance, dimensional stability and better recovery, while viscose or rayon gives softness, absorbency, drape and a more comfortable handle.
If a fabric is made from 100% polyester, it may be strong and easy to maintain, but it can feel less absorbent and less comfortable in warm conditions. If a fabric is made from 100% viscose, it may be soft and drapey, but it may wrinkle easily and may not retain shape as well as a polyester-rich fabric.
TR fabric tries to balance these two behaviours. In very simple terms, polyester makes the fabric more practical, while viscose makes the fabric more wearable.
The blending idea can be expressed as:
\( \text{TR Fabric Performance} = f(\text{Polyester Strength}, \text{Viscose Comfort}, \text{Weave}, \text{Finish}) \)
This formula is not a laboratory equation, but a useful way to remember the idea. The final performance of TR fabric does not depend only on fibre content; it also depends on yarn, weave, finishing and garment construction.
TR fabric is popular because it gives a practical combination of formal appearance, durability and affordability. This is especially useful in markets where garments must look neat, withstand repeated use and remain within a moderate price range.
A well-made TR suiting fabric usually has a smooth surface, good fall, acceptable crease recovery and better resistance to daily wear than many soft cellulosic fabrics. However, the quality can vary widely, so the fabric name alone should never be treated as a guarantee of performance.
| Property | Practical Meaning in TR Fabric |
|---|---|
| Strength | Usually better than pure viscose because of the polyester component. |
| Drape | Generally better than 100% polyester because viscose improves fall and handle. |
| Wrinkle Resistance | Better than cotton or pure viscose, especially when polyester percentage is higher. |
| Comfort | Usually better than pure polyester, but not as breathable as cotton or linen. |
| Appearance | Smooth, formal and suitable for trousers, suitings and uniforms. |
| Maintenance | Easier to maintain than wool suiting, but garment care still depends on construction. |
| Cost | Generally more economical than wool-rich suiting fabrics. |

TR fabric is most commonly associated with suiting and formalwear. In India, it is widely seen in men’s trousers, formal suits, safari suits, waistcoats, blazers, corporate uniforms, school uniforms and institutional clothing.
The reason is simple: these garments require a clean appearance, reasonable durability, acceptable crease recovery and controlled cost. TR fabric meets these requirements better than many fabrics at the same price level.
| End Use | Why TR Fabric is Suitable |
|---|---|
| Formal trousers | Good crease recovery, smooth appearance and reasonable durability. |
| Men’s suits | Affordable suiting option with a formal look and good fall. |
| School uniforms | Durability, easy maintenance and consistent availability. |
| Corporate uniforms | Neat appearance, repeatable quality and controlled cost. |
| Safari suits | Structured look, practical wearability and formal character. |
TR fabric should not be understood in isolation. It is best understood by comparing it with 100% polyester, cotton and wool suiting because these are common alternatives in formalwear and uniform fabric selection.
Compared with pure polyester, TR fabric usually feels softer and more comfortable because of the viscose component. Compared with cotton, it usually wrinkles less and gives a more formal trouser-like appearance. Compared with wool suiting, it is usually cheaper and easier to maintain, but it does not have the same premium natural handle.
| Fabric Type | Main Strength | Main Limitation | Typical Use |
|---|---|---|---|
| TR Fabric | Balanced formal appearance, durability and moderate comfort. | May feel synthetic if polyester percentage is very high. | Trousers, suits, uniforms and office wear. |
| 100% Polyester | High durability, wrinkle resistance and easy care. | Lower absorbency and sometimes less comfortable in heat. | Uniforms, linings, sportswear and functional apparel. |
| Cotton | Good breathability and comfort. | Wrinkles easily and may require more ironing. | Shirts, casual wear, summer wear and uniforms. |
| Wool Suiting | Premium appearance, natural drape and tailoring elegance. | Higher cost and more careful maintenance. | Premium suits, jackets and formal tailoring. |
A customer may not always be able to identify TR fabric only by looking at it. However, TR fabric usually has a smooth suiting-like surface, moderate body, good fall and better wrinkle recovery than cotton or pure viscose.
When crushed gently in the hand, TR fabric generally recovers better than cotton. It may also have a slightly synthetic resilience, but a softer touch than pure polyester because of the viscose or rayon component.
For accurate identification, one should check the fabric label, mill specification, invoice description or test report. Market names can be confusing, so a fabric sold as TR should ideally be supported by a declared fibre composition and basic quality parameters.
For buyers and merchandisers, TR fabric should be evaluated beyond the name. Important points include blend ratio, GSM, width, shrinkage, colour fastness, pilling tendency, handle, fall, crease recovery and suitability for the intended garment.
For trousers, the fabric should have enough body, recovery and surface stability. For uniforms, durability, shade consistency and washing performance are important. For suits, drape, handle and surface appearance become more important.
| Buying Checkpoint | Why It Matters |
|---|---|
| Blend ratio | Determines the balance between durability, comfort and cost. |
| GSM and construction | Affects body, fall, opacity and garment suitability. |
| Finish | Improves appearance, handle, crease recovery and dimensional stability. |
| Colour fastness | Important for uniforms and repeat-use garments. |
| Pilling resistance | Important because poor-quality blends may develop surface pills with wear. |
| Shrinkage control | Essential for trouser length, waist fit and garment consistency. |

TR fabric is generally easier to maintain than wool suiting, but the correct care method depends on the final garment. A simple trouser made from TR fabric may be washable, while a structured coat or suit jacket may require dry cleaning because of lining, interlining, shoulder pads and tailoring construction.
High heat should be avoided during ironing or tumble drying because polyester-containing fabrics can be affected by excessive temperature. It is always better to follow the garment care label rather than assuming the same care method for every TR fabric.
TR fabric is a practical polyester-viscose or polyester-rayon blended fabric, mainly used for suitings, trousers, uniforms and formalwear. Polyester contributes strength, crease recovery and durability, while viscose contributes softness, drape and better comfort.
The most important point is that TR is a commercial fabric category, not a single fixed quality. A good TR fabric depends on the right blend ratio, yarn, weave, finish and end-use suitability.
This article is intended for general textile education and practical fabric understanding. Fabric names such as TR, Terry Rayon, Terylene Rayon and poly-viscose may be used differently by different mills, traders and retailers, so actual fibre composition and performance should be confirmed through supplier specifications, labels or testing wherever accuracy is required.
The properties discussed here are general indications and may vary according to fibre blend, yarn count, weave structure, GSM, dyeing, finishing and garment construction. For commercial buying, product development or quality approval, actual fabric samples and test reports should be evaluated before final decisions are made.
Reactive dyes occupy a very important place in textile printing, especially for cellulosic fibres such as cotton and viscose. Among them, Procion reactive dyes are well known because they can produce bright shades with good washing and light fastness.
For a textile student, Procion dyes are also interesting because they connect three things together:
Procion dyes are a class of reactive dyes. They are called reactive because they do not merely deposit colour on the fibre surface. Instead, they react with the cellulose fibre and form a chemical bond.
This is the key idea.
In many dyes, the colour may remain attached to the fibre through physical attraction or weak forces. But in reactive dyes, the dye molecule chemically combines with the fibre. Because of this, the print becomes more durable.
This chemical bonding is the reason why Procion dyes generally show good fastness properties.

Cotton and viscose are both cellulosic fibres. Their structure contains hydroxyl groups, which can react with reactive dyes under suitable alkaline conditions.
That is why Procion dyes are mainly used for printing fabrics such as:
When the right amount of alkali, moisture, temperature and time are provided, the dye reacts with the fibre and becomes fixed.
Since the dye forms a chemical bond with the fibre, the printed colour can withstand washing better than many non-reactive dye systems.
Procion dyes also give reasonably good resistance to light, depending on the shade and dye selection.
Reactive dyes are known for producing clear and bright shades. This makes them suitable for printed dress materials, sarees, furnishings and many other cotton-based products.
Different Procion dyes can be combined to obtain a wide variety of colours and tones.

Procion dyes can be broadly divided into three classes:
The main difference between them is their reactivity.
Reactivity means how quickly and easily the dye reacts with the fibre.
Procion-H dyes are the least reactive among the three groups.
Because they are less reactive, the printing paste prepared with them remains stable for a longer time. This is useful in textile printing because printing paste may have to remain usable during production.
However, because Procion-H dyes are less reactive, they need proper fixation conditions. They are mainly suitable where fixation is done by the steaming process.
Procion-H dyes are slow-reacting but stable.
So, they are useful when:
Procion-Supra dyes are more reactive than Procion-H dyes.
They give good washing fastness and are useful where somewhat higher reactivity is needed.
Procion-Supra dyes can also be used along with Procion-H dyes in many cases.
Procion-Supra dyes are a middle category.
They are more reactive than Procion-H, but they still offer reasonable process stability.
Procion-M dyes are highly reactive.
Because of their high reactivity, they are widely used in textile printing. They can be used not only in steaming processes but also in certain methods where steaming is not used.
They are also suitable for resist-style printing.
However, there is one important caution.
Because Procion-M dyes are highly reactive, their printing paste does not remain stable for a long time. Therefore, Procion-M paste should be prepared only in the quantity required for immediate use.
Procion-M dyes are fast-reacting dyes.
They are useful when:
| Dye Type | Reactivity | Paste Stability | Main Use |
|---|---|---|---|
| Procion-H | Low | High | Mainly steaming process |
| Procion-Supra | Medium | Good | Printing where better reactivity and fastness are required |
| Procion-M | High | Low | Quick fixation, resist style, wider process use |
Most Procion dyes are compatible with one another and can be used to produce many shades.
However, one practical point is important:
This is because their reactivity levels are quite different. One reacts slowly, while the other reacts quickly. This difference may create problems in shade development and fixation.
On the other hand:
In textile printing, the dye cannot be applied like a simple liquid. It has to be converted into a paste so that it remains on the printed area and does not spread uncontrollably.
For this purpose, a thickener is used.
For Procion reactive dyes, the commonly used thickener is:
Sodium alginate is preferred because it is suitable for reactive dye printing. It helps create a smooth printing paste and does not interfere seriously with the dye-fibre reaction.
A good thickener should:
This is why sodium alginate is generally used for Procion dyes.
A printing paste for Procion dyes generally contains:
Each ingredient has a specific role.
This is the colouring matter. It reacts with the cellulosic fibre and gives the desired shade.
Urea helps in dissolving the dye and retaining moisture during fixation. Moisture is important because the dye-fibre reaction needs suitable conditions.
For cotton fabrics, urea is generally used in the range of:
For viscose fabrics, it is generally used in the range of:
The exact amount depends on the process and steaming conditions.
Water dissolves the dye, urea and alkali and helps in preparing a workable paste.
Sodium alginate acts as the thickener. It gives body to the printing paste and helps produce clean printed designs.
Resist salt helps prevent unwanted effects during printing, especially in roller printing and discharge-related situations. It also helps control unwanted reduction or discharge effects.
Alkali is essential for the reaction between Procion dye and cellulose fibre.
Without alkali, the dye may remain only deposited on the fabric and may not properly react with the fibre.
Common alkalis include:
The choice of alkali depends on the dye type and process.
A stock thickening paste is first prepared, generally using sodium alginate. The required dye is then added and mixed thoroughly. A high-speed stirrer is used so that the ingredients are properly dispersed.
| Ingredient | Stock Paste | Reduction Paste |
|---|---|---|
| Procion dye | 50 parts | — |
| Urea | 50–200 parts | 50–200 parts |
| Water | 490–240 parts | 540–290 parts |
| Sodium alginate thickener | 350 parts | 350 parts |
| Resist salt | 10 parts | 10 parts |
| Alkali: sodium bicarbonate or sodium carbonate | 25 parts or 15 parts | 15 parts |
| Total | 1000 parts | 1000 parts |
One common method is as follows:
The paste should be smooth, uniform and free from lumps.

Paste stability is very important in printing.
The paste of Procion-H and Procion-Supra dyes can remain usable for a longer time, up to about 28 days.
But Procion-M paste is not stable for long because the dye is highly reactive.
This is a very practical point in production. If highly reactive dye paste is stored for too long, the dye may lose its effectiveness, and the print quality may suffer.
Procion dyes are reactive dyes used mainly for printing cotton and viscose fabrics. They form a chemical bond with cellulose fibre and give good washing and light fastness.
The three main types are:
Sodium alginate is commonly used as the thickener. Urea, alkali, resist salt and water are important ingredients in the printing paste.
The most important technical point is that reactivity and paste stability are connected. A highly reactive dye like Procion-M works quickly but has lower paste stability. A less reactive dye like Procion-H is slower but more stable.
In reactive dye printing, alkali is not just an additive. It is the chemical trigger that allows the dye to react with cellulose.
Without alkali, the dye may colour the fabric, but it will not be properly fixed.
A common mistake is to treat all Procion dyes as if they behave the same way.
They do not.
Procion-H, Procion-Supra and Procion-M differ in reactivity, paste stability and suitable fixation method. Understanding this difference is essential for successful printing.
Why should Procion-M printing paste be prepared only when required, while Procion-H paste can remain usable for a longer time?
The answer lies in one word:
Reactivity.
