How many kinds of fast-drying clothing material?
Synthetic Fiber Category
Polyester fiber (polyester):
It is the first major variety of synthetic fibers, the moisture return rate is extremely low, the fiber structure is close to round in cross-section, can be made into triangular, Y-shaped, hollow and other special cross-sectional shape of the fiber, can improve the moisture absorption of the clothes, quick-drying ability, is the most widely used fabrics in the quick-drying clothes.
Nylon (nylon):
The price is a little higher than polyester, better abrasion resistance, but moisture absorption and stiffness is not as good as polyester, often blended with spandex and other elastic fibers, used in the production of sportswear and other quick-drying clothing.
Sorona:
Developed by DuPont in the U.S., Sorona is injected with biotechnology into chemical fiber fabrics, which is more environmentally friendly and renewable, and has good moisture wicking performance.
Coolmax:
A functional fiber technology developed by DuPont, now part of INVISTA. Its fiber cross-section is cross-shaped, the formation of four grooves, increasing the surface area of the fiber, accelerating the diffusion of water and evaporation, through the fiber grooves of the capillary effect of the skin surface of the sweat quickly guided to the outer layer of the fabric to achieve unidirectional moisture transfer.
Supplex:
DuPont developed a nylon fabrics, delicate and soft feel, touch like cotton fabrics, breathability and cotton fabrics comparable. Its fiber is ultra-fine, porous structure, with siphon function, can quickly transfer the body surface sweat to the surface of the fabric and accelerate the evaporation, but also has a windproof, water-resistant, lightweight, easy to take care of the characteristics.
Natural fiber class
Merino wool:
The fiber is very hydrophilic, able to absorb 30% of its own weight of water, to maintain a sense of dryness. The fibers are fine, forming countless tiny air pockets, storing a large amount of air layers, which can cushion heat waves in summer and help regulate body temperature. It also has good breathability, which helps to keep the skin dry and cool, and the fiber structure makes it impossible for bacteria to breed on it, reducing the chances of odor production.
Other Specialty Fabrics
Polartec Power Dry:
A two-layer construction with a hydrophilic inner layer and a hydrophobic outer layer. The inner layer rapidly absorbs sweat from the skin surface through capillary action, while the outer layer accelerates the diffusion of moisture by expanding the evaporation area. The surface is a fine mesh-like fleece, the other side is smooth, and the thickness is thin, elastic and comfortable against the skin.
Schoeller 3xdry:
Through a special finishing process, sweat is channeled from the body to the surface of the fabric, where it dissipates quickly, keeping the wearer cool and dry. 3xdry bio and ecorepel bio, two PFC-free finishing processes, have been developed, based on renewable agricultural by-products, and do not contain harmful PFCs.
Wickron:
Japanese outdoor brand montbell independently developed quick-drying fabric, made of 99.9% polyester fiber, through the design of shaped yarn to enhance the surface area of the fiber, to enhance the efficiency of moisture absorption and perspiration, the touch is soft and close to cotton, and at the same time to avoid the shortcomings of cotton moisture absorption is easy to slate.
Omni – dry:
Columbia’s moisture absorption and quick-drying functional fabrics, water absorption can be 3 times that of ordinary cotton, through a special fiber structure to quickly absorb moisture on the surface of the body and guided to the outer layer of the fabric evaporation of water evaporation rate of 2 times that of ordinary cotton, but also has a windproof warmth function.
Activent:
The high performance quick-drying fabric developed by American gore company, using film material design, both windproof, breathable and resisting the function of slight moisture, need to be compounded with nylon and other materials, through the multilayer structure to strengthen the durability and functionality of the fabric, with the effect of inhibiting the growth of bacteria.
Flashdry:
The North Face developed a patented quick-drying fabric technology, through the fiber structure design to simulate the function of the “second skin”, actively adsorbing and transferring the moisture on the surface of the skin to the outer layer of the fabric, and accelerating the evaporation with the help of the body temperature and the environmental temperature to keep the body surface dry and cool quickly.
Factors affecting the rate of fabric drying?
Factors affecting the drying rate of textiles mainly include the following:
Textiles own factors
Fiber characteristics
Hydrophilic and hydrophobic: hydrophilic fibers such as cotton, hemp, etc., can quickly absorb water, but relatively slow release of moisture; hydrophobic fibers such as polyester, nylon, etc., moisture absorption is poor, but the water is easy to evaporate. Blended fibers can balance the rate of moisture absorption and drying, such as 65% polyester/35% cotton blended fabrics.
Fiber structure:
the supramolecular structure of the fiber affects the ability to absorb moisture, such as viscose fiber amorphous zone accounted for a high proportion of moisture absorption than cotton. Fine denier fiber woven fabric surface has a micro-convex structure, capillary core suction effect is obvious, can improve the breathable and water-conducting sweat performance.
Yarn factors
Yarn twist: high-twist yarn fiber inter-fiber pore reduction, the core suction speed is reduced; low-twist yarn is conducive to water conduction. Such as twist > 1000 twist / m of high twist yarn, core absorption rate may be reduced by 30%.
Yarn structure:
the moisture absorption of core yarn fabrics is better than that of entangled yarn fabrics as a whole, but the air permeability and evaporation rate of entangled yarn fabrics are better than that of core yarn fabrics in general.
Fabric structure
Density and thickness: high density, thick fabrics core absorption height and drying rate is usually lower, such as 300t polyester taffeta core absorption height of only 2-3cm, while 210t fabrics up to 5cm.
Organizational structure: different organizational structure of the fabric drying rate differences, such as plain fabric warp and weft yarns staggered more often, more water evaporation per unit of time, evaporation rate faster than twill fabrics.
External environmental factors
Temperature:
the higher the temperature, the more intense the molecular thermal movement, the faster the water evaporation rate. Such as in 30 ℃ environment, cotton drying time is shorter than at lower temperatures.
Humidity:
the greater the humidity of the air, the slower the evaporation of water. When the humidity ≥ 87%, the moisture in the fabric is difficult to evaporate, and it will even feel more humid because the yarn absorbs moisture.
Wind speed: the greater the wind speed, can accelerate the evaporation of moisture on the surface of the fabric, take away the moisture, so that the drying rate increases. Such as in the natural environment, windy clothes dry faster than when there is no wind.
Processing technology factors
Pre-treatment process:
insufficient pre-treatment will lead to fiber surface impurity residue, affecting the absorption and evaporation of water. If the cotton desizing is not sufficient, the starch residue will prolong the diffusion time.
Shaping process:
shaping temperature is too high will make the fiber molecular chain rearrangement, hydrophilic groups are wrapped, hygroscopicity decline, drying rate slows down. Such as polyester molding temperature > 190 ℃, the core absorption height will drop.
Finishing process:
the use of hydrophilic finishing agent can improve the hydrophilicity of the fiber, speed up the drying rate; and excessive softener may reduce the core absorption effect, affecting the drying.
How does a drying rate tester work?
The Heated Plate method tests how fast fabric dries when it is exposed to water. It does this while the fabric is on a heated plate. This test uses a hot plate at 37 degrees Celsius or 99 degrees Fahrenheit. It is to replicate the temperature at which the human body starts to perspire. The temperature drops when the specimen is wet. As it dries, the temperature slowly rises. The start time, end time, and drying time. The goal is to calculate the drying rate.
What parameters can a drying rate tester control?
including airflow/circulation, material application thickness, and test interval times. More advanced models allow customizing multiple parameters to mimic real-world drying conditions.
How precisely can a drying rate tester measure drying time?
Lab-grade testers can measure drying within just a few minutes. Accuracy depends on the model and sensors. Some claim accuracies of just 1-2 minutes. This depends on the test parameters and material.
The drying testing machine measures how fast materials dry. It measures fabric, clothes, and other materials too. It objectively tests the drying time under controlled conditions.
