The variety and applications of decorative rugs are actually quite extensive—let me help you sort them out clearly:

I. Classification by Material

Natural fiber carpet

Wool carpet: Fine and dense wool fibers with excellent elasticity, resistant to dust accumulation, naturally flame-retardant, featuring exquisite patterns and elegant colors. It provides sound absorption and warmth, offering a comfortable feel underfoot.
Silk carpet: soft and smooth, durable and wear-resistant, with a brilliantly glossy surface that exudes elegance and luxury. It’s highly resilient, moisture-absorbent, and features exquisite patterns.
Cotton rug: With a rough yet soft and comfortable texture, it’s durable and wear-resistant, making it ideal for bathrooms, entrances, dining rooms, and other spaces.
Hemp rug: natural and eco-friendly, with a rugged texture, perfect for modern minimalist styles.

Chemical fiber carpet

Nylon carpet: durable and wear-resistant, resistant to shedding, not easily absorbent of liquids, available in a wide range of colors, noise-reducing and dust-suppressing—ideal for indoor spaces with high foot traffic.
Polyester carpet: moderately priced, easy to clean, resistant to fading, and suitable for home use.
Acrylic carpet: Soft to the touch and highly warm-retentive, making it ideal for bedrooms, living rooms, and other areas.
Polypropylene carpet: wear-resistant and corrosion-resistant, ideal for humid environments such as toilets and bathrooms.

Blended carpet

Wool/nylon blend: Combines the softness of wool with the abrasion resistance of nylon, making it ideal for both residential and commercial settings.
Wool/viscose blend: Cost-effective, available in a wide variety of patterns, and ideal for large-area installations.

Other types of carpets

Plastic carpet: Lightweight, waterproof and moisture-resistant, ideal for outdoor or humid environments.
Rubber rugs: Vibrant colors, excellent elasticity, wear and aging resistance, and superior non-slip performance—perfect for spaces such as bathrooms, shower rooms, basements, and more.
Silk woven carpet: Made from high-quality mulberry silk, hand-woven for a soft, smooth texture that is durable and wear-resistant. The carpet surface boasts a bright, lustrous sheen, exuding elegance and luxury—perfect for high-end decor.
II. Classified by Application

Localized placement: Position it in the center of the living room, in front of the guest seating, under the piano, or near room entrances and exits. Suitable for high-end carpets such as wool rugs and silk rugs.
Full-floor carpeting: Covering the entire floor of a room with carpet, suitable for machine-woven synthetic fiber carpets made of acrylic, polypropylene, nylon, and other synthetic fibers, as well as tufted carpets.
Overlapping installation: Partially laying small carpet tiles over a fully laid carpet, suitable for synthetic fiber tufted carpets.
