How to Choose Yarn for Knitted Fabrics: A Practical Guide for Textile Manufacturers
Choosing the right yarn is one of the most important decisions in knitted fabric manufacturing. The yarn affects the fabric's softness, appearance, stretch, strength, durability and overall production cost. A yarn that works well for a T-shirt may not be the right choice for a sweatshirt, sportswear or home textile.
For textile manufacturers, the challenge is not simply finding yarn at the right price. It is finding a yarn that performs consistently throughout knitting and meets the requirements of the finished fabric. Whether you are developing a new garment collection or looking for a reliable knitting yarn supplier in India, understanding the basics of yarn selection can help you make better sourcing decisions.
What is knitting yarn?
Knitting yarn is a continuous strand of fibres used to create fabric through interlocking loops. Unlike woven fabrics, knitted fabrics are formed by connecting loops of yarn, which gives them flexibility, stretch and comfort. Knitting yarn can be made from natural fibres such as cotton, synthetic fibres such as polyester, or recycled and blended materials. The best yarn depends on the intended application. For example, cotton yarn is commonly used for comfortable everyday garments, while polyester blends may be selected when strength and durability are important.
1. Understand the end use of the knitted fabric
Before choosing yarn, identify what the fabric will be used for.
Different garments require different combinations of softness, strength, weight and stretch.
Fabric application | Important yarn characteristics |
T-shirts | Softness, comfort and good fabric appearance |
Polo shirts | Strength, smoothness and dimensional stability |
Hoodies and sweatshirts | Suitable yarn count, durability and fabric weight |
Sportswear | Strength, comfort and moisture-management requirements |
Socks | Flexibility, abrasion resistance and suitable stretch |
Babywear | Softness and appropriate chemical safety requirements |
Home textiles | Durability, appearance and cost efficiency |
For instance, a yarn suitable for a lightweight T-shirt may not provide the structure required for a heavier sweatshirt. Start with the fabric specification rather than selecting yarn based only on price.
2. Choose the right fibre composition
Fibre composition influences how a knitted fabric feels and performs.
Cotton yarn
Cotton is widely used for knitted garments because of its natural feel, comfort and moisture absorption. It is a practical choice for T-shirts, casualwear and other garments worn close to the skin. SVSM Group offers 100% cotton knitted yarns in combed compact and carded compact varieties, with counts ranging from Ne 10s to Ne 50s. These options can be considered when developing cotton-based knitted fabrics. Explore the 100% Cotton Knitted Yarn range to compare available options.
Recycled yarn
Recycled yarn is another option for manufacturers developing more sustainable textile products. It can be made from recycled textile waste, recycled polyester or a combination of recycled fibres. When sourcing recycled yarn, check the recycled content, fibre composition, quality consistency and certification requirements.
SVSM Group produces recycled yarn from pre-consumer and post-consumer textile waste. Its recycled yarn range includes cotton-polyester blends, recycled polyester and other fibre combinations for knitting applications.
Blended yarn
Blended yarn combines two or more fibres to achieve a particular balance of performance and cost. For example, a cotton-polyester blend may be selected when the manufacturer wants a combination of cotton's natural feel and polyester's durability. The correct blend depends on the fabric construction, garment requirements and buyer specifications.
3. Select the correct yarn count
Yarn count indicates the fineness or thickness of yarn. In the English cotton count system, commonly written as Ne, a higher count generally indicates a finer yarn.
For example:
Ne 20s is generally thicker than Ne 30s.
Ne 30s is generally thicker than Ne 40s.
Ne 40s is generally finer than Ne 20s.
The right count depends on the required fabric weight, knitting machine settings and final garment design.
Why yarn count matters
A finer yarn may be suitable for lightweight knitted fabrics, while a coarser yarn may be selected for heavier fabric constructions. However, yarn count alone does not determine the final GSM or fabric quality. Stitch length, loop structure, yarn composition and finishing also influence the result. SVSM's recycled knitting yarn range includes counts from Ne 2s to Ne 40s, while its 100% cotton knitted yarns are available from Ne 10s to Ne 50s. This provides manufacturers with options across different fabric constructions.
4. Compare ring spun and open-end yarn
The spinning method affects yarn characteristics and its suitability for different knitted fabrics.
Ring spun yarn
Ring spun yarn is produced using ring spinning technology. It is commonly selected for applications where softness, appearance and yarn quality are important. SVSM's ring spun yarn range includes 100% cotton knitted yarns, organic cotton options, BCI blends and recycled yarn blends. Its products are manufactured using compact and carded compact spinning techniques.

Open-end yarn
Open-end, also called rotor spun yarn, is produced using rotor spinning technology. It is used in a range of textile applications, including knitted fabrics.
The choice between ring spun and open-end yarn should be based on the required fabric appearance, strength, softness, production efficiency and cost.
SVSM Group offers Open End and Rotor Spun Yarn for different textile manufacturing requirements.
5. Check yarn strength and consistency
Yarn strength is important because the yarn must withstand the tension and movement involved in knitting.
Weak or inconsistent yarn can lead to problems such as:
Yarn breakage during knitting
Uneven fabric appearance
Irregular loops
Production delays
Increased material wastage
Before placing a large order, ask the supplier about yarn strength, count variation, evenness and quality-control procedures.
A reliable knitting yarn supplier in India should be able to explain how yarn quality is monitored and provide relevant test information.
6. Consider softness, hairiness and fabric appearance
The feel and appearance of knitted fabric depend on more than fibre composition.
Yarn hairiness, evenness, twist and spinning method can influence the final result.
For garments such as T-shirts and babywear, softness and a comfortable hand feel may be important. For certain fashion fabrics, a specific texture or visual effect may be preferred. If the fabric needs a smooth surface, compact yarn may be worth considering. If the design calls for a textured appearance, a slub yarn or another specialty yarn may be more appropriate. The best approach is to test the yarn in the actual fabric construction before approving bulk production.
7. Choose recycled knitting yarn based on the application
Sustainability is becoming an important consideration for textile manufacturers and fashion brands. However, recycled yarn should be selected based on both environmental objectives and fabric performance.
When evaluating recycled knitting yarn in India, consider:
Recycled content
Ask whether the yarn is made from recycled cotton, recycled polyester or a blend. Confirm the composition and whether it meets your buyer's requirements.
Yarn count
Make sure the available count is suitable for your knitting machine and target fabric.
Colour consistency
Pre-dyed recycled yarn can be useful when consistent colour is required. SVSM uses colour sorting and mechanical recycling to produce pre-dyed recycled yarn without a conventional dyeing stage.
Certification and traceability
Certifications and transaction documents can help support recycled-content claims and supply-chain transparency. SVSM's recycled yarn range includes GRS, GOTS, OEKO-TEX, OCS and RCS certifications, among others. Its website also describes transaction certificates for recycled yarn batches. You can explore SVSM's Recycled Yarn to understand its available blends, counts and recycled yarn applications.
8. Check colour availability and customisation
Colour plays an important role in garment development. A yarn may meet the technical requirements but still be unsuitable if the required shade is unavailable.
Ask your supplier about:
Available colour shades
Heather and mélange options
Custom colour development
Minimum order quantity
Shade approval process
Batch-to-batch colour consistency
SVSM offers more than 75 recycled yarn shades and customisable yarn options, including blend compositions and colour requirements. Its team also conducts trials and quality validation for customised products. For colour-based sourcing, visit the SVSM Colour Shade Card and request the available shade options.
9. Consider certifications and quality documentation
For many textile buyers, yarn certification is an important part of supplier evaluation. Depending on the product and market, certifications may help demonstrate compliance with recycled-content, organic-content, chemical-safety or social-responsibility requirements. Before ordering, ask for the certifications relevant to your product and confirm whether the specific yarn being supplied is covered by the required certification. SVSM Group lists GRS, GOTS, OEKO-TEX Standard 100, OCS, RCS and other certifications on its website. Read more about Yarn Certifications at SVSM.
10. Compare cost, availability and supplier support
The lowest yarn price is not always the lowest production cost.
A yarn that causes frequent knitting problems, inconsistent fabric quality or delivery delays may increase the overall cost of manufacturing.
When comparing suppliers, consider:
Yarn price per kilogram
Quality consistency
Minimum order quantity
Production lead time
Availability of samples
Technical support
Certification documentation
Ability to supply repeat orders
A good supplier should understand your fabric requirements and help you select the right yarn rather than simply offering the cheapest option.
