SMS Non-woven Fabric vs. SF Coated Non-woven Fabric: A Comparison of Protective Clothing Materials!

Non-woven fabric protective clothing is widely used, applicable tothe medical industry, chemical industry, food industry, etc.It can be used not only in GMP pharmaceutical production and food production industries forcleanroom protection.It ensures a sterile and dust-free cleanroom environment; it can also be used formedical protection,preventing cross-infection between medical staff and patients; additionally, it can be used forlabor protection,protecting workers from pollutants, etc. Among the many protective clothing materials,SMS non-woven fabric and SF coated non-woven fabric are two common materials.This article will detail the differences between these two materials, as well as their respective advantages and application scenarios.

SMS non-woven fabric protective clothing

1. Material composition

SMS non-woven fabric, full name,Spunbond-Meltblown-Spunbondwhere S stands for spunbond, M stands for meltblown, that is,spunbond-meltblown-spunbond non-woven fabric,is a three-layer composite non-woven fabric.

2. Advantages and characteristics

①Filtration performance:The middle layer ofMeltblown non-woven fabric has a fine fiber structure,which can effectively filter bacteria, viruses, and other small particles.

②High strength:Due to the use of Spunbond technology, SMS non-woven fabric hashigh tensile strength and tear strength,and can withstand certain mechanical pressures.

③Good breathability:SMS non-woven fabric hasgood breathability,so that wearers do not feel hot when wearing it for long periods.

④Good comfort:The material is soft and hasno irritation to the skin,making it comfortable to wear.

3. Protective performance

SMS non-woven fabric performs excellently in protective performance,with a filtration efficiency of over 99%, providing goodbarrier effect against bacteria, viruses, and other small particles.However, its protective performance is affected by the following factors:Hydrostatic pressure:

①Due to the larger pores of the non-woven fabric, SMS non-woven fabric has a lower hydrostatic pressure and relatively poor waterproof performance.Liquid penetration:

②When encountering high-speed jetting liquids, the protective performance of SMS non-woven fabric decreases and cannot completely prevent liquid penetration.SF coated non-woven fabric protective clothing

SF coated non-woven fabric, full name,

1. Material composition

where S stands for spunbond, F stands for coating, is a material with a layer ofSpunbond-Filmpolyethylene (PE) film coated on the surface of spunbond non-woven fabric.Waterproof performance:The PE film on the surface of the coated non-woven fabric has excellent waterproof performance,

2. Advantages and characteristics

①effectively preventing liquid penetration and ensuring the safety of the wearer.High tensile strength:Spunbond non-woven fabric as the base material ensures that the coated non-woven fabric hashigh tensile strength and tear strength.

②Anti-pollution performance:The surface of the coated non-woven fabric is smooth and easy to clean,effectively preventing the growth of bacteria and viruses.

③Compared to SMS non-woven fabric,SF coated non-woven fabricexcels in protective performance:Waterproof and anti-penetration:

3. Protective performance

The PE film on the surface of the coated non-woven fabric can effectivelyprevent water, blood, body fluids, and other liquids from penetrating,reducing the risk of infection.

①Filtration efficiency:Although the filtration efficiency of the coated non-woven fabric isslightly lower than that of SMS non-woven fabric,it can still reach over 99%, meeting protective needs.

②Application scenarios of protective clothing1. Medical industry (medical protection): isolation wards, infectious disease areas, intensive care units, operating rooms, etc.【No sterilization required: prevent cross-infection; sterilization use: for example, operating rooms】Used for

防护服应用场景

1.医疗行业（医用防护）：隔离病区、传染病区、重症监护室、手术室等

【无需灭菌：防止交叉感染；灭菌使用：比如手术室】

用于Isolation wards, infectious disease areas, intensive care units, operating rooms, and other environments. After wearing, it prevents cross-infection, providing protection for patients and healthcare personnel.Bilateral protection. Generally, protective clothing is mainly to prevent the patient's viruses and bacteria from infecting the doctor, while inthe operating room, sterilization treatment is required, to prevent the bacteria on doctors and nurses from contaminating the patients.

①SMS non-woven fabric:Widely used indisposable surgical gowns, isolation gowns, protective clothingand other fields. In low-risk environments, SMS non-woven fabric protective clothing can meet daily protection needs.

②SF coated non-woven fabric:Mainly used inhigh-risk environmentsfor protective clothing, itsexcellent waterproof and protective performance,allows coated non-woven fabric protective clothing to better protect the safety of workers.

2. Industrial field (cleanroom protection): GMP pharmaceuticals, food production, sterile laboratories, etc.

[No sterilization required: Protecting the human body from contaminating the cleanroom; sterilization use: Ensuring a sterile environment to avoid affecting experimental results/product quality]

①SMS non-woven fabric:用于Biological laboratories in clean environments, GMP production workshopsand so on, used to protect the human body from contaminating the cleanroom.

②SF coated non-woven fabric:用于Chemical laboratories, food processing plantsand other places with high requirements for waterproofing and antibacterial properties.

3. General field (labor protection): Painting, animal husbandry, pesticide spraying, etc.

①SMS non-woven fabric:More suitable for protecting workers handling dry particles, such asmining, wood processingand so on;

②SF coated non-woven fabric:better waterproof protection, such aspesticide spraying, chemical handling.

Comparison of protective clothing materials

1. Comparison of protective performance:

In terms ofprotective performance,SF coated non-woven fabric is superior to SMS non-woven fabric.Especially inwaterproof and permeation resistance,coated non-woven fabric hasa significant advantageand can effectively reduce the risk of infection.2. Comparison of comfort:

In terms of comfort, SMS non-woven fabric has a slight advantage.

Due to its soft texture, it is comfortable to wear and suitable for long-term use. However,due to the PE film coating on the surface,SF coated non-woven fabricits breathability is relatively poor,which may affect the wearing experience.3. Comparison of application scenarios:

In terms of application scenarios, both materials have their advantages.

SMS non-woven fabric is suitable for low-risk environments,such as general hospitals, laboratories, etc.; whileSF coated non-woven fabric is more suitable for high-risk environments,such as infectious disease areas, operating rooms, etc.Summary

Non-woven fabric protective clothing plays an important role in ensuring the safety of various workers.

SMS non-woven fabric and SF coated non-woven fabric have their pros and cons in protective performance, comfort, and application scenarios.When purchasing protective clothing, one should choose the appropriate material based on actual needs and environmental risks.在选购防护服时，应根据实际需求和环境风险，选择合适的材质。
