Can recycled cotton be used as sound insulation cotton?

Recycled cotton can be used as soundproofing cotton and is widely used in many occasions, especially in projects that pursue both environmental protection and cost-effectiveness. The following is a detailed introduction by point:

1、 The advantages of using recycled cotton for soundproofing cotton
▸Good sound absorption performance
The structure of recycled cotton is mostly composed of loose and interlaced short fiber layers, which have good sound absorption effect
Has good attenuation ability for mid to high frequency noise (such as human voice, mechanical sound)

▸Environmental protection and energy saving
The raw materials come from waste cotton textiles or scraps, which conforms to the concepts of sustainable development and circular economy
Reduce resource waste and carbon emissions, suitable for the demand of green building materials

▸low cost
Cheaper than traditional soundproofing materials such as rock wool and glass wool
Specially suitable for large-scale construction or budget constrained projects

▸No irritation
Recycled cotton does not contain easily itchy particles such as fiberglass, making it safer and more friendly during construction
No need to wear special protective clothing to operate

2、 Common application scenarios of recycled cotton soundproofing materials
▸Home decoration
As a sound insulation cushion layer between walls, ceilings, and floors
Used for sound insulation treatment in bedrooms, study rooms, audio-visual rooms, and other areas

▸Commercial buildings
Soundproofing layer for hotels, offices, conference rooms, KTVs and other places
Filling soundproof cotton in the sandwich wall structure to improve privacy

▸Industrial equipment sound insulation
Used to cover noise sources such as generators, air compressors, fans, pipelines, etc
Combining damping layer to enhance overall noise reduction effect

▸Automobile and Ship Manufacturing
Used as soundproofing material for structures such as car doors, floors, ceilings, etc
Improve ride comfort and reduce noise transmission

3、 Precautions for use
▸Moisture and mildew prevention treatment
Recycled cotton is essentially a natural fiber or blended material with strong moisture absorption, requiring the addition of a moisture-proof layer or coating treatment

▸Flame retardant performance needs to be enhanced
Raw recycled cotton does not have flame retardancy and requires the addition of flame retardants or composite use with flame retardant layers

▸Thickness and density control
The sound insulation effect is closely related to the thickness and density of the cotton layer, and the design should be selected according to the usage scenario

▸Not suitable for high-end sound insulation requirements
Compared to professional polyester sound-absorbing cotton or mineral cotton, its sound insulation coefficient is slightly lower and not suitable for high-end recording studios and other precision places
