Women's Tank

 This women's vest is made of a blend of 65% rayon, 30% nylon, and 5% spandex, and is designed in size S. The rayon (viscose fiber) provides a soft feel against the skin and excellent moisture-wicking and breathability, while the nylon enhances the fabric's strength and shape stability. The 5% spandex content provides lateral and longitudinal stretch recovery. The knitted loop structure creates longitudinal stretch in the fabric, suitable for everyday casual wear, either alone or layered. The shoulder straps and neckline feature a bound hem, ensuring a smooth finish for a close-fitting look.

Core Advantages

65% Rayon: 13% moisture regain, higher moisture absorption rate than cotton fiber, cooling coefficient of 0.18-0.20
30% ​​Nylon: Dry breaking strength 4.0-5.0 cN/dtex, reducing wrinkles and deformation
5% Spandex: ≥95% tensile recovery rate, maintaining a close fit to the garment structure
Weft-knitted plain weave: 15%-25% longitudinal elongation, accommodating a range of motion
Edging: Neckline and armhole edges are bound with the same fabric, thickness controlled within 0.3cm

Product Characteristics
Moisture Absorption and Breathability: The porous structure of rayon fibers ensures moisture conduction rates suitable for summer wear.
Form Stability: Nylon component reduces shrinkage after washing, warp shrinkage ≤3%.
Elastic Fit: 5% spandex distributed throughout the fabric, chest stretch 8-12cm
Touch: Rayon surface smoothness is superior to cotton fiber, with a coefficient of friction of 0.25-0.30
Wrinkle Resistance: The blended structure reduces the wrinkle-prone nature of pure rayon fabric, with a 2-hour recovery rate of ≥70%.
Colorfastness: Reactive dyeing process, colorfastness to soap washing ≥3-4 grade.

Frequently Asked Questions

Q: What is the difference between rayon and pure cotton?

A: Rayon is a regenerated cellulose fiber with a moisture absorption rate of 13%, higher than cotton's 8.5%, resulting in faster drying and a smoother feel. Its wet strength is lower than cotton, requiring gentle washing. The price is generally lower than pure cotton products of the same specifications.

Q: Does 30% nylon affect breathability?

A: Nylon is blended in yarn form and does not clog the gaps between rayon fibers. The knitted structure maintains a porosity of 12%-18%, meeting daily breathability needs. Nylon mainly enhances durability and is not a barrier layer.

Q: Is it normal for the shoulders to loosen after wearing?

A: Knitted fabrics have a 5%-8% plastic deformation rate, and the shoulder straps may stretch by 1-2cm under long-term stress. It is recommended to rotate wearing the garment and avoid hanging it under the same weight for several consecutive days. Lying it flat to dry after washing will partially restore its shape.

Q: Why is low-temperature washing recommended?

A: The wet expansion rate of rayon fibers is approximately 80%. High temperatures accelerate molecular chain slippage, which may lead to irreversible shrinkage. A water temperature of 30°C can control the warp shrinkage rate within the standard of 3%.
