(6) Waterproof and breathable functional fabric
Waterproof and breathable fabric means that water does not infiltrate the fabric under a certain pressure, but the sweat emitted by the human body can be transmitted to the outside through the fabric in the form of water vapor, thereby avoiding the accumulation of sweat and condensation between the body surface and the fabric to keep the clothing comfortable It is a high-tech, unique functional fabric. Waterproofing is not a problem for ordinary fabric workers, the key is how to achieve moisture permeability. Below, we take a deeper look at it from the types of waterproof and breathable fabrics.
1. Moisture permeability through fiber
1. Ventel fabric. The earliest waterproof and breathable fabric is the famous Ventile fabric. It was designed by the Shirley Research Institute in the UK in the 1940s. It uses high-count low-twist cotton yarn with high density and heavy flat weave from Egyptian long-staple cotton. It was originally mainly used for the cold protection of British Air Force pilots during World War II Anti-dip clothing. When the fabric is dry, the gap between the warp and weft yarns is large, about 10 microns, which can provide a highly moisture-permeable structure; when the fabric is rained or watered, the cotton yarn expands, reducing the gap between the yarns to 3 to 4 microns. This closed-cell mechanism is combined with a special water-repellent finish to ensure that the fabric is not further penetrated by rain. At present, this kind of fabric has been replaced by other waterproof and breathable fabrics.
2. Coolmax fabrics. International companies such as DuPont and Toray Japan have researched the method of making holes in the fiber to remove sweat from the body, which is the moisture wicking fabric on the market. This type of fiber production technology is concentrated in the hands of such large international companies, the price is relatively high, and it is difficult to become the mainstream of the market.
Second, through the coating to achieve moisture permeability
Using dry direct coating, transfer coating, foam coating, phase inversion or wet coating (solidified coating) and other process technologies, a variety of waterproof and moisture-permeable coating agents are applied to the fabric On the surface of the fabric, the pores on the surface of the fabric are closed or reduced to a certain extent by the coating agent, thereby obtaining waterproofness. The moisture permeability of the fabric is through the microporous structure formed on the coating by a special method or the hydrophilic group in the coating agent interacts with the water molecule. With the help of hydrogen bonding and other intermolecular forces, the water molecule is adsorbed on the high humidity side. Obtained by the analysis function transferred to the low temperature side. Coated fabrics are low in price, have achieved a certain degree of moisture permeability, and are widely used. However, due to its poor waterproof and moisture-permeable performance and unsatisfactory feel, the market share is gradually decreasing.
The wet transfer coating fabric developed now makes the coated fabric renewed. It not only has high physical properties such as waterproof and moisture permeability, but also can be treated with 100% Teflon, and the washing fastness can reach 25 times. Above, the feel is also very good.
3. Moisture permeability is achieved by laminating waterproof and moisture permeable membranes
1. PTFE film
The diameter of the water vapor molecule is 0.0004 microns, and the diameter of the lightest mist in the rain water is 20 microns. The diameter of the drizzle has been as high as 400 microns. If a film with a pore diameter between water vapor and rain can be made, it is waterproof. Isn't it possible to achieve breathability again? GORE of the United States used polytetrafluoroethylene (PTFE) to become the first company to produce the film, and after the composite lamination with the fabric, the trade name was GORE-TEX. But because PTFE is very chemically inert, there are few materials that can be laminated well with other fabrics. The first-generation fabrics have very poor fastness.
Later, after continuous efforts, by submerging with other hydrophilic film layers to form a composite film, and special treatment on the film, the fastness is greatly improved. It is generally believed that the water pressure of Gore-Tex fabrics can reach 10000mm, and the water pressure only drops significantly after 6-7 washings; the maximum moisture permeability can reach 10000g / sqm * 24hrs, but this is not just the fabric just made Reaching this value requires several washings to wash away some of the glue. The available pores increase and the moisture permeability increases.
2. TPU film
TPU is the abbreviation of thermoplastic polyurethane film, which belongs to non-porous hydrophilic film. Since the film itself has no pores, the waterproof effect is naturally very good, and it also makes the fabric windproof and warm. Moisture permeability is mainly achieved through its hydrophilic characteristics. Depending on the difference in vapor pressure between the inside and outside of the clothes, the steam is transferred from the place with high pressure to the place with low pressure, thereby achieving the function of moisture permeability.
(7) Anti-radiation fabric
There are two main types of radiation protection fabrics on the market
Functional winter clothes
Functional winter clothes atlas
1. Metal fiber fabric 2. Metalized fabric
Metal fiber fabric:
The stainless steel metal is drawn into very fine and thin silk, and then blended with fabric fibers.
Wire and fiber are mixed together. The advantage of this fabric is that it is breathable. It looks no different from ordinary fabrics. But after the fabric burns, it will leave a metal net. Can be washed.
The protection is suitable for family watching TV and office work. Under normal circumstances, it can play a good role in protection
Xingbao shopping network agent Tianxiang radiation protection clothing is made using this type of fabric.
The method of electrolysis is that the metal penetrates into the fabric to form a metal conductor, thereby achieving electromagnetic shielding.
The advantage is: strong protection ability, suitable for telecommunication transmitter room.
The disadvantage is that the fabric is relatively thick and the air permeability is not very good. It is suitable for places close to high-power telecommunications transmitters and other places with high-power radiation. The fabric cannot be washed. Generally manufacturers are made detachable. The radiation protection fabric can be disassembled.
(8) Antibacterial and deodorant fiber fabric
In 1955, Japan successfully developed a fiber fabric with antibacterial function. Metals or salts can destroy the metabolic function of bacterial cell membranes, leading to the death of bacteria, thereby playing a sterilizing role. In recent years, many other inorganic and organic antibacterial agents have also been developed, which can impart antibacterial and deodorant properties to fiber fabrics and textiles through blending, composite spinning or finishing . With the development of society and the improvement of people's living standards, antibacterial and deodorant fiber fabrics and textiles have a promising future.
(9) Electromagnetic wave shielding fiber fabric
With the popularity of mobile phones, computers, microwave ovens and other office and household appliances, the harm of electromagnetic wave radiation is becoming increasingly prominent. In order to protect the human body from or minimize the harm of electromagnetic radiation, the electromagnetic radiation source can be shielded to reduce the amount of radiation; it can also wear effective anti-electromagnetic radiation protection fabrics for self-protection.
(10) Medical functional fiber fabric
Medical functional fiber is the product of the intersection of life science and materials science, and is an important material basis for the development of modern clinical medicine. Medical functional fibers have been used to varying degrees in surgical transplantation, in vitro artificial organs, and medical accessories.
(11) Far infrared functional fiber fabric
The far-infrared fiber fabric has excellent health care physiotherapy, moisture removal, ventilation and bacteriostatic functions. It can absorb the heat emitted by the body itself, absorb and emit far-infrared rays of the wavelength that the body needs most, promote blood circulation and have a warming effect . The ideal far-infrared fabric has good thermal insulation, antibacterial and physical therapy functions. At present, far-infrared textiles developed at home and abroad mainly include underwear, pants, and cushions.
(12) Smart fiber fabric
At present, smart textiles developed using smart fibers mainly include automatic color-adjusting clothing, automatic temperature-adjusting clothing, "smart T-shirts" with "perception" and adaptive protective clothing. Photochromic fibers and thermochromic fibers can be made into smart ski jackets, jackets, blouses, dresses and hats, etc. They can change colors with changes in indoor and outdoor light. This kind of clothing is very popular among consumers because of its good light, thermal discoloration and novelty. With self-adaptive temperature-adjusting clothing, its temperature can change with the change of human body and ambient temperature, and it can protect the body without changing or less changing the loading load. The "smart T-shirt" woven from plastic optical fibers and conductive fibers can assist medical personnel to monitor the patient's physiological indicators such as heartbeat, body temperature, blood pressure, breathing, etc., and can also be used by the monitoring personnel to understand and grasp the Physical conditions can also be made into baby pajamas to monitor the baby's breathing to prevent the baby from suffocating during sleep. The United States has developed a new type of smart protective clothing. It will automatically send out an alarm signal after being scratched, which can better protect the safety of workers in radioactive and toxic environments.
