| Fiber Definition |
Microfiber describes very fine synthetic fibers, while spandex provides elastic stretch. |
Microfibers are commonly below 1 decitex per filament. Spandex is an elastomeric polyurethane fiber. |
Request the fiber composition and individual filament fineness on the technical data sheet. |
| Fiber Composition |
The blend affects softness, moisture behavior, durability, cost, and care requirements. |
Typical constructions use polyester or polyamide microfiber blended with approximately 5–20% spandex. |
Choose the blend according to the product: polyester for durability and cost efficiency; polyamide for a softer hand and higher abrasion resistance. |
| Fabric Weight |
GSM, or grams per square meter, indicates fabric weight and usually influences coverage, drape, and perceived quality. |
Common apparel weights are approximately 120–250 GSM, depending on the knit or woven construction. |
Use lighter weights for base layers and activewear; use heavier weights for leggings, swimwear, uniforms, or structured garments. |
| Stretch Direction |
Stretch may be available across the width only or in both length and width. |
Two-way stretch is common in basic constructions; four-way stretch is preferred for close-fitting and movement-oriented garments. |
Match stretch direction with the pattern and conduct a stretch test on both the course and wale directions. |
| Stretch and Recovery |
Stretch measures how far the fabric extends; recovery measures how well it returns to its original dimensions. |
Performance varies significantly by yarn count, spandex percentage, knitting structure, and finishing process. |
Set a product-specific minimum recovery requirement and test after repeated extension, washing, and drying cycles. |
| Softness and Hand Feel |
Fine filaments create a smooth surface and can improve comfort against the skin. |
Polyamide microfiber generally feels softer and silkier; polyester microfiber can offer a smooth feel with strong durability. |
Approve a physical swatch before bulk purchasing and compare softness, surface uniformity, and pilling after laundering. |
| Moisture Management |
Moisture behavior depends on fiber type, yarn structure, fabric construction, and finishing treatments. |
Microfiber fabrics can spread liquid over a larger surface area and may dry quickly, but they are not automatically moisture-wicking. |
Request test results for wicking, drying rate, and air permeability rather than relying only on the term “microfiber.” |
| Dimensional Stability |
Shrinkage and distortion can affect garment fit, cutting accuracy, and returns. |
Results depend on fiber content, heat setting, finishing, and care conditions; no single shrinkage value applies to every fabric. |
Specify an acceptable dimensional-change limit and test samples using the intended laundering method before production. |
| Colorfastness |
Colorfastness indicates resistance to color transfer, washing, perspiration, rubbing, and light exposure. |
Performance varies by dye class, shade, fiber type, and finishing process. Dark and bright shades often require closer testing. |
Request test reports based on applicable ISO or AATCC methods and evaluate both dry and wet rubbing. |
| Abrasion and Pilling |
These properties influence service life and the fabric’s appearance after repeated wear. |
Fine fibers provide a smooth surface but may pill if yarn structure, finishing, or friction resistance is unsuitable. |
Test the actual fabric construction under the expected use conditions, especially for sportswear, uniforms, and high-friction areas. |
| End-Use Suitability |
The best specification depends on the final product, wearing conditions, required fit, and care instructions. |
Common applications include activewear, swimwear, leggings, underwear, shapewear, dancewear, and fitted uniforms. |
Prioritize stretch and recovery for fitted garments, softness for next-to-skin products, and abrasion resistance for workwear. |
| Compliance and Care |
Chemical compliance, labeling accuracy, and care performance help reduce regulatory and quality risks. |
Care instructions should reflect the actual fiber blend and finishing process; excessive heat can damage or reduce the performance of elastane. |
Confirm fiber-content labeling, restricted-substance requirements, wash-care instructions, and batch-to-batch consistency before shipment. |
