Our role is to help buyers identify suitable fibres, yarn specifications, compositions and sourcing arrangements before proceeding to fabric development, sampling and bulk apparel manufacturing.

All materials are subject to yarn availability, technical feasibility, commercial volume, supplier confirmation and applicable documentation.

## 1. Apparel Fibre and Yarn Sourcing Services
The selection of fibres and yarns is a fundamental stage of apparel development.

Fibre characteristics, yarn quality, spinning technology, blend ratios and speciality effects influence the appearance, comfort, drape, durability and manufacturing suitability of a finished garment.

Mirthuni Apparel coordinates yarn sourcing and material development based on buyer specifications.

Our services include:

- Conventional and premium cotton yarn sourcing

- Carded, combed and compact-spun yarn selection

- Organic cotton sourcing

- Cotton origin and sustainability programme sourcing

- Recycled cotton and recycled polyester yarn sourcing

- Modal, lyocell, viscose and bamboo viscose yarn sourcing

- Branded fibre sourcing evaluation

- Cotton-polyester and cotton-modal blended yarns

- Cotton-lyocell and bamboo-cotton blended yarns

- Two-component and three-component yarn compositions

- Melange, marl and heather yarn sourcing

- Neppy, slub, injected slub and grindle yarn sourcing

- Twisted and multi-ply yarn development

- Yarn-dyed and speciality colour sourcing

- Yarn count and spinning specification selection

- Material traceability and certification review

- Custom yarn sampling and procurement coordination

The final yarn selection depends on the intended garment, technical specifications, supplier capabilities and production volume.

## 2. Understanding Fibre, Yarn and Finished Fabric Composition
A fibre is the raw material used to manufacture yarn.

Yarn is formed by spinning fibres or assembling suitable filaments into a continuous textile material.

A finished fabric may contain one fibre type or a combination of different fibres.

Examples include:

- 100% cotton

- 60% cotton / 40% polyester

- 50% cotton / 50% modal

- 70% bamboo viscose / 30% cotton

- 60% cotton / 35% modal / 5% elastane

It is important to distinguish between **yarn composition and finished fabric composition**.

For example, a fabric containing 60% cotton and 40% polyester may be produced using a blended yarn or a combination of separate cotton and polyester yarns.

Similarly, elastane may be introduced through a suitable knitting system rather than being incorporated into the primary spun yarn.

Our yarn sourcing process considers:

- Fibre composition

- Fibre origin

- Spinning method

- Yarn count

- Yarn construction

- Colour and speciality effects

- Supplier documentation

- Finished material requirements

Knitting structures, plating arrangements, GSM and finished fabric construction are covered separately on our Knitting and Knitted Fabric Development page.

Mirthuni Apparel provides **apparel yarn sourcing** support for international clothing brands seeking conventional cotton, premium cotton, regenerated cellulosic fibres, recycled yarns and custom blended compositions.

Our **apparel yarn sourcing** services include melange, marl, heather, slub, neppy and other speciality yarn developments through selected spinning mills and yarn suppliers.

For custom **apparel yarn sourcing** enquiries, buyers can share their required fibre composition, yarn count, colour, speciality yarn effect and expected production quantity.

## 3. Conventional Cotton Yarn
Cotton is one of the principal fibres used in knitted apparel.

It is widely selected for T-shirts, polo shirts, sweatshirts, hoodies, joggers, knitted shorts, loungewear, sleepwear and children's garments.

We can evaluate cotton yarns produced using different preparation and spinning methods.

### 3.1 Carded Cotton
Carded cotton yarn is produced through conventional cotton fibre preparation and spinning.

It may be considered for suitable casualwear developments where the buyer's required handfeel, surface appearance and price parameters can be achieved.

### 3.2 Combed Cotton
Combed cotton undergoes additional fibre preparation intended to remove a portion of shorter fibres and improve yarn uniformity.

It is commonly selected for premium apparel requiring a smoother surface and more consistent appearance.

### 3.3 Compact-Spun Cotton
Compact spinning is a yarn manufacturing process designed to improve fibre integration and reduce yarn hairiness.

Compact cotton yarn may be considered for premium apparel developments requiring a cleaner yarn surface.

### 3.4 Ring-Spun Cotton
Ring spinning is widely used to manufacture apparel yarns.

Ring-spun cotton may be available in carded, combed and compact-spun specifications depending on the supplier and spinning process.

### 3.5 Open-End Cotton
Open-end, or rotor-spun, cotton yarn may be evaluated for selected casualwear applications.

Its properties differ from ring-spun yarn and should be assessed against the intended garment requirements.

## 4. Organic Cotton and GOTS Sourcing
Organic cotton may be considered for buyers requiring organic fibre content and supporting supply-chain documentation.

Mirthuni Apparel can evaluate organic cotton yarn from suitable suppliers according to the required yarn count, composition and commercial volume.

Where requested, sourcing may involve suppliers participating in the Global Organic Textile Standard (GOTS) certification system.

A finished garment cannot automatically be described as GOTS-certified merely because organic cotton was used.

Any GOTS product claim requires appropriate certification and transaction documentation covering the relevant supply-chain stages and finished product.

Organic cotton availability and minimum quantities are confirmed for each project.

## 5. Better Cotton — Formerly Associated with BCI
[Better Cotton is an international cotton sustainability](https://bettercotton.org/) programme historically associated with the Better Cotton Initiative (BCI).

We can evaluate Better Cotton-related sourcing through suitable participating suppliers where available.

Buyers should distinguish between programme-based cotton sourcing, physical traceability and finished-product claims.

Mass-balance sourcing does not automatically establish that a particular garment physically contains traceable Better Cotton.

Applicable sourcing and marketing claims must comply with the relevant Better Cotton programme requirements.

## 6. Supima Cotton
Supima is a recognised brand associated with American-grown extra-long-staple Pima cotton.

Supima yarn may be considered for premium T-shirts, polo shirts and other selected high-quality knitted garments.

Sourcing depends on yarn count, supplier availability, order volume and supporting documentation.

Use of the Supima name, logo and related product claims requires appropriate verification and applicable brand authorisation.

## 7. U.S. Cotton and COTTON USA
U.S.-origin cotton may be considered for buyers requesting specific cotton origins.

COTTON USA is a trademark associated with Cotton Council International.

Depending on eligible yarn supply, we can evaluate U.S.-origin cotton and COTTON USA-related sourcing requirements.

The origin of cotton fibre, the origin of yarn manufacturing and eligibility to use a promotional trademark are distinct matters.

Any origin or trademark claim must be appropriately documented.

## 8. Australian Cotton
Australian-grown cotton may be evaluated for selected apparel yarn sourcing programmes.

Availability depends on suitable yarn counts, spinning arrangements, supply channels and commercial quantities.

Australian cotton origin claims require appropriate supplier documentation.

## 9. Cotton made in Africa (CmiA)
Cotton made in Africa (CmiA) is a recognised cotton sustainability standard and sourcing programme.

We can evaluate CmiA-associated sourcing through suitable participating suppliers, subject to yarn availability and programme requirements.

Any CmiA-related traceability or marketing claim must comply with the applicable sourcing and trademark rules.

## 10. Recycled Cotton Yarn
Recycled cotton may be produced from suitable pre-consumer or post-consumer textile materials.

It may be blended with virgin cotton, polyester or other compatible fibres according to the required yarn characteristics.

Potential applications include casual T-shirts, sweatshirts, hoodies, joggers and selected knitted garments.

Recycled cotton yarn characteristics depend on recovered fibre length, fibre quality, blend composition and spinning technology.

We can evaluate recycled cotton sourcing associated with the Global Recycled Standard (GRS) or Recycled Claim Standard (RCS) where required.

Certification and recycled-content claims require valid documentation for the relevant supply chain and product.
