Cotton-polyester blend - The "durability god" of hospital bedding
Cotton-polyester blend - The "durability god" of hospital bedding
Key words: T/C 65/35, breaking strength, anti-wrinkle and non-ironing, resistance to hypochlorite bleaching
In the daily operation of a hospital, the bedding has to withstand not only the weight of patients' bodies, but also the "harsh treatment" of daily high-temperature disinfection and intense washing. Under such circumstances, the polyester-cotton blended fabric, thanks to its outstanding durability, has become the favorite of the hospital's logistics department.
The scientific proportion of cotton and polyester blend
The most common polyester-cotton blend ratio in current hospital procurement is T/C 65/35, which means a blend of 65% polyester fibers and 35% cotton. This golden ratio has been verified through years of practice and has achieved the best balance between performance and comfort:
1.The function of polyester fiber (65%)
Provide extremely high tensile strength and wear resistance
Ensure that the fabric does not wrinkle easily after washing, achieving the "washable and wearable" effect.
Enhance the tolerance to strong oxidizing bleaching agents such as hypochlorites
2. The role of cotton fibers (35%)
1.Maintain a certain level of moisture absorption and breathability
Improve the fabric's texture and reduce static electricity generation
Maintain the patient's acceptable level of comfort
2. Core technical indicators of polyester-cotton blended fabric
According to the hospital procurement announcement of 2026, the technical requirements for the polyester-cotton blended bedding are extremely strict:
Physical performance indicators
Weave count: 32×32s, density 130×70
Per unit area weight: ≥ 220g per square meter
Breaking strength: Weft direction ≥ 300N, Warp direction ≥ 350N
Tear strength: Weft direction ≥ 15N, Warp direction ≥ 17N
Washing shrinkage rate: -3% to 1.5%
2. Chemical Safety Indicators
Formaldehyde content: ≤ 75mg/kg
Fastness: Wash fastness, acid sweat fastness, and alkali sweat fastness are all ≥ 4 grades.
Chlorine peroxide whitening fastness: ≥ 4 grades
No odor
3. Antibacterial performance indicators
E. coli antibacterial rate: > 99%
Antibacterial rate of Staphylococcus aureus: > 99%
Antibacterial rate of Candida albicans: > 99%
3. Why is polyester-cotton blended fabric indispensable in hospitals?
1.Extremely durable, reducing the frequency of replacements
The industrial washing process in the hospital can be described as "harsh": temperatures above 80°C, strong alkaline detergents, sodium hypochlorite bleaching, and high-speed dehydration and drying. For pure cotton fabrics, in such an environment, the fibers are prone to breaking, hardening, and shrinking. However, the high strength of polyester enables it to withstand more than 300 industrial washings without significant deterioration.
2. Anti-wrinkle and stain-resistant, saving labor costs
Pure cotton bedding must be processed by a ironing machine after washing; otherwise, wrinkles will affect the tidiness of the ward. The polyester-cotton blended fabric has natural anti-wrinkle properties and can remain flat even after simple drying, significantly reducing the workload of the laundry room.
3. Resistant to bleaching, ensuring a sterile environment
Hospital disinfection cannot do without chlorine-based disinfectants. The polyester-cotton blended fabric has excellent tolerance to hypochlorite bleaching, with color fastness reaching grade 4 or above. Even after repeated bleaching, it will not turn yellow or fade.
4. Application Scenarios and Procurement Suggestions
Cotton-polyester blended bedding is most suitable for the following scenarios:
General ward: Frequent daily cleaning required, thus demanding extreme durability.
Emergency Department/ICU: High risk of contamination, requires frequent disinfection and bleaching.
Psychiatric/Rehabilitation Department: There may be violent pulling, requiring anti-tear protection.
Purchase Note: Although the polyester-cotton blend is durable, it has less moisture absorption than pure cotton. For patients who are bedridden for a long time and sweat a lot, it is recommended to add a pure cotton absorbent pad under the bed sheet to ensure both comfort and durability.
