Description

Medical textile

Technical Field

The utility model relates to the field of medical treatment, in particular to a medical textile.

Background

Medical textile such as doctor clothing, patient clothing, hospital bed articles and other various textile articles with huge quantity need to be used in the medical system, along with the development of science and technology, the development of novel fibers and the research and development of novel manufacturing processes of yarns and fabrics, the medical textile also advances towards new application fields, and the materials and the structure of the medical textile are diversified according to the purposes. For medical care clothes, the waterproof and antifouling clothes are required, and have the advantages of good air permeability, beautiful appearance and the like. Common medical garments fall into two broad categories, natural and non-natural.

The natural fabric comprises cotton, linen, silk, cashmere/wool and leather. However, the natural fabric used as medical care clothing is only cotton, and the other four fabrics are far from each other in price and practicability. Cotton, the most common natural fabric, has over 50% of the ready-made garments made from cotton textiles. Cotton cloth can be classified into pure cotton and non-pure cotton fabrics according to the content of cotton. Its advantage does: the operating coat made of cotton cloth is soft and close-fitting, has good hygroscopicity and air permeability, and is relatively durable. But also has the defects of easy shrinkage, easy wrinkle, ironing and easy hardening after being washed.

In the impression of the immobilization rule, we will always default to natural fabrics being better than artificial non-natural fabrics. Otherwise, most medical garment brands on the market are made of non-natural fabrics, which shows that the non-natural fabrics have advantages. The non-natural fabric used for medical care clothing is generally synthetic fiber in chemical fiber, such as nylon, terylene, acrylon, spandex and the like. Generally, the chemical fiber fabrics are bright in color, soft in texture, stiff and smooth in suspension, and comfortable. However, some fabrics are inferior in wear resistance, heat resistance, moisture absorption, and air permeability, and are easily deformed and easily generate static electricity.

The fabric determines the texture of the garment, and even the work clothes such as medical care clothes need to be more exquisite while emphasizing the practicability. Because the good fabric can make the whole person be high-grade, doctors and nurses are refreshing, and the confidence of patients on medical care is enhanced. Therefore, the medical clothes with better effect can absorb moisture, perspire, prevent static electricity and improve the germ blocking rate.

One square inch of GORE-TEX film had 90 hundred million micro-holes. And one drop of water bead 4 is 2 ten thousand times larger than the micro holes, water cannot penetrate through the micro holes, and 100% water resistance is achieved.

2. Ventilating: each micro-pore is 700 times larger than the sweat molecules of the human body, and the sweat 5 can pass through the cloth easily. The air permeability specification is g/m/24hr (the amount of water vapor passing through the unit area in a fixed time), the general waterproof and air permeable cloth is only 2000-3000g/m/24hr, and the air permeability of the Goretex membrane is up to 8000-10000g/m/24 hr.

3. The product is durable: the three-layer composite cloth can prevent pollutants, blood, body fluid and OPIM from penetrating, and has long service life.

The outer layer 1 is the outer layer fiber of the knitted fabric formed by high-moisture-conductivity quick-drying chemical fiber, the outer layer fiber is the chemical fiber which has a special-shaped cross section and forms a superfine capillary tube in the longitudinal direction to provide an excellent channel for quickly transferring moisture, and the wearability of the garment is greatly improved. The inner layer fiber can be hygroscopic natural fiber to protect skin. The outer layer 1 makes the polyester fiber 10 have a special-shaped section by utilizing the shape of a specially designed spinneret orifice. The filament yarn formed by multiple strands of fiber, such as polyester filament yarn, with the micro structure contained in the special-shaped cross section comprises a cross section with an outline shape, and a fine channel is formed in the longitudinal direction, so that the filament yarn has extremely strong water liquid transferring capacity by virtue of the wicking action of a capillary tube. The inner layer of the fabric is the next-to-skin wearing surface. Sweat is rapidly transferred through the inner fabric layer to the outer fabric layer 1 through the core layer 2.

The inner layer 3 is a fabric formed by hygroscopic fibers, can absorb water, quickly disperse and discharge around, and keep the surface of the skin dry and comfortable.

The medical textile composite fabric has the following technical advantages:

electrostatic prevention: the use of the conductive carbon fibers ensures that the fabric keeps permanent antistatic performance and can give consideration to the attractive appearance and comfortable hand feeling of the fabric.

Bacteriostasis and deodorization: medical care and food processing industries require that uniform fabrics have a bacteriostatic function so as to reduce the probability of bacterial contact infection of working environments and ensure the safety of personnel and products. The antibacterial and bacteriostatic functions of the fabric reach the SEK red marking standard of Japan.

Sweat absorption and quick drying: the fabric has a micro-groove conduit effect due to the special-shaped cross-section fibers, sweat discharged by a human body rapidly reaches the surface of the fabric through a large amount of conduits due to the siphonage phenomenon and is diffused and volatilized, the uniform of the frock is helped to keep a dry and comfortable state, and the wearing comfort is improved.

Inner cotton and outer polyester: the three-dimensional weaving technology can enable the fabric to have the characteristic of double-sided heterogeneity. The part contacting the skin surface of a human body is made of natural fibers which are compatible with the skin, and particularly the health of the skin needs to be protected for industries needing long-term skin-close wearing.

Ventilation and comfort: the three-dimensional weaving technology enables the fibers to keep a curved and spiral loop shape in the fabric. The fibers have sufficient gaps, so that the circulation of air can be ensured, and the stuffiness feeling in the wearing process can be reduced.

Ironing-free crease-resistance: the components of the synthetic fiber can ensure that the fabric has excellent elasticity and recoverability, good shape retention and high strength. The wrinkles formed by wearing the clothes in the daytime can be effectively recovered and eliminated after being hung and placed at night. After washing, the clothes are hung and dried, so that the clothes are smooth and attractive, convenient and efficient.

Beautiful and anti-penetration: summer work uniform for medical staff requires coolness, thinness and has a good shielding function so as to protect personal privacy. The fabric with special cross section and luster fibers woven by adopting a three-dimensional weaving technology meets the beauty pursuit of summer women.

The disinfection is convenient: the working environment of the medical care personnel is difficult to avoid contacting with various germs and viruses. The high-temperature disinfection and chlorine bleaching treatment at 150 ℃ can effectively kill germs, thereby not only ensuring the self health of medical care personnel, but also fully reflecting the care of patients.
