Application of polyester hot melt yarn in the medical field: actual cases and professional analysis
1. Introduction to polyester hot melt yarn
Polyester hot melt yarn is a functional fiber with low melting point, thermoplasticity and self-adhesiveness. Its melting point is usually between 110℃ and 180℃, and different melting points can be achieved by adjusting the raw material properties. After this fiber is woven into a fabric with other fibers at room temperature, when it is heated above its melting point, the hot melt yarn will melt and bond other fibers, and form a strong bond after cooling. Polyester hot melt yarn not only has good thermal bonding properties, but also has the advantages of wear resistance, chemical corrosion resistance and uniform dyeing.
2. Application of polyester hot melt yarn in the medical field
(I) Medical protective clothing
In the field of medical protection, polyester hot melt yarn is widely used in the production of medical protective clothing. Protective clothing needs to have good waterproof and anti-penetration properties, while maintaining a certain degree of breathability and comfort. Polyester hot melt yarn can bond multiple layers of fabric together through a hot melt process to form a seamless protective structure, which effectively prevents the penetration of viruses and bacteria. For example, some high-end protective clothing uses polyester hot melt yarn as the middle layer, combined with other waterproof and breathable materials, which not only ensures protective performance but also improves the comfort of wearing.
(II) Medical masks
In the production of medical masks, polyester hot melt yarn also plays an important role. It is used for the nose bridge and ear strap fixation of the mask and the bonding between multiple layers of non-woven fabrics. Through the hot melt process, polyester hot melt yarn can firmly bond the various layers of the mask together to ensure the structural stability and sealing of the mask. This bonding method not only improves production efficiency, but also avoids the skin irritation and environmental pollution that may be caused by the use of chemical adhesives.
(III) Medical dressings
In the production of medical dressings, polyester hot melt yarn is used to make wound dressings with waterproof, breathable and antibacterial functions. These dressings need to keep the wound dry while allowing the skin to breathe and promote wound healing. Polyester hot melt yarn can bond fiber layers with different functions together through the hot melt process to form a multi-layer structure dressing. For example, some new medical dressings use polyester hot melt yarn as the middle layer, combined with absorbent fibers and breathable fibers, which can effectively absorb wound exudate while maintaining the breathability and antibacterial properties of the dressing.
(IV) Medical device packaging
The packaging of medical devices needs to have good sealing and antibacterial properties to ensure that the medical devices remain sterile before use. Polyester hot melt yarn is used in the production of medical device packaging materials. Multiple layers of non-woven fabrics or plastic films are bonded together through a hot melt process to form a sealed packaging structure. This packaging material not only has good waterproof and antibacterial properties, but also can withstand certain pressure and impact to protect the integrity of medical devices during transportation and storage.
(V) Medical protective gloves
Medical protective gloves need to have good waterproof, anti-penetration and wear resistance, while maintaining a certain degree of flexibility and comfort. Polyester hot melt yarn is used in the production of gloves. Multiple layers of materials are bonded together through a hot melt process to form a seamless glove structure. This type of glove can not only effectively prevent the penetration of viruses and bacteria, but also maintain wear resistance and flexibility during long-term use.
3. Practical application cases
(I) Protective clothing production case
A medical protective clothing manufacturer used polyester hot melt yarn as the middle layer material during the production process. Through the hot melt process, the polyester hot melt yarn is bonded with the waterproof and breathable outer layer material and the moisture-absorbing and perspiration-wicking inner layer material to form a three-layer protective clothing. This protective clothing shows good waterproof, breathable and antibacterial properties in actual use, effectively protecting medical staff from viruses and bacteria.
(II) Mask production case
A medical mask manufacturer used polyester hot melt yarn as the fixing material for the nose bridge and ear straps in the production of masks. Through the hot melt process, the polyester hot melt yarn is bonded with the non-woven fabric material to form a firm mask structure. This mask shows good sealing and comfort in actual use, and can effectively filter viruses and bacteria in the air.
(III) Dressing production case
A medical dressing manufacturer used polyester hot melt yarn as the middle layer material during the production process. Through the hot melt process, polyester hot melt yarn is bonded with absorbent fiber and breathable fiber to form a multi-layer dressing. This dressing shows good water absorption, breathability and antibacterial properties in actual use, and can effectively promote wound healing.
(IV) Medical device packaging case
A medical device manufacturer uses polyester hot melt yarn as the middle layer material in the packaging process. Through the hot melt process, polyester hot melt yarn is bonded with non-woven fabric material and plastic film to form a sealed packaging structure. This packaging material shows good waterproof and antibacterial properties in actual use, and can effectively protect the sterile state of medical devices during transportation and storage.
(V) Protective gloves production case
A medical protective glove manufacturer uses polyester hot melt yarn as the middle layer material in the production process. Through the hot melt process, polyester hot melt yarn is bonded with wear-resistant material and soft material to form a seamless glove structure. This glove shows good waterproof, wear-resistant and flexibility in actual use
