Antibacterial microfiber has an excellent function

The production of ultra-fine fibers in China has been accelerated under the promotion of international and domestic markets, and the production capacity of ultra-fine fibers nationwide has exceeded 100,000 tons/year.

 Polyester and nylon composite microfibers are characterized by the differences in the chemical structure of PET and PA polymers, the weak interfacial bonding force, and the ability to separate from each other. During the production process, super-composite fibers are formed by melt spinning at a certain ratio. Antibacterial microfibers are made by adding antibacterial agents to chemical fibers in the form of blends or masterbatch to produce durable antimicrobial fibers. The fiber produced by this method can reach the linear density of microfibers. The average single fiber is about 0.2dtex. This line density is equivalent to 1/5~1/10 of the silk, giving the fabric good physical and chemical properties. In the textile cleaning supplies and clothing industry has been promoted.

 The so-called microfiber refers to microfibers with a diameter of 0.4mu, and its fiber degree is only 1/10 of a special wedge-shaped cross-section of silk so that it can effectively capture even a few micrometers of dust particles from the surface of the wipe, decontaminating and degreasing. The effect is very obvious. Microfiber fabrics are made of polyester and nylon. For polyester/nylon two-component composite microfibers, which are widely used in industrial textiles and made of a stripping method, fiber-opening is a crucial step, and it directly determines whether or not ultra-fine fibers can be truly formed. Whether multiple indicators of microfiber can be achieved. The alkaline solution is used to dissolve some of the components of the composite fiber to obtain ultra-fine fibers. The microfiber gives the product a larger specific surface area and more microscopic voids, which greatly enhances the ability of the product to adsorb particulates. This feature can be used to make face masks, filter membranes, and the like.

 The antibacterial microfibers are produced using both imported and domestic antibacterial agents, and the fiber opening rate after fabric dyeing and finishing is about 90%. The antibacterial properties of Staphylococcus aureus, Klebsiella pneumonia, and Escherichia coli stained with antibacterial composite microfiber DTY filaments and warp-knitted terry fabrics were tested. The results showed that the antibacterial effects of fiber and dyed fabrics reached the Japanese fiber evaluation The blue and orange standards of the technical association SEK require high antibacterial effects.

 In order to further determine the antimicrobial durability of antimicrobial fibers, dry and hot heat treatment was performed on the antimicrobial composite microfibers, and the antimicrobial effect of the treated fibers was tested using Staphylococcus aureus. The results showed that antibacterial POY after the 170 °C, 220 °C stereotypes heat treatment, and 95 °C boiling treatment, the antibacterial properties of the basic maintenance of the pre-treatment level, with excellent antibacterial effect. After heat setting and boiling experiments, the antimicrobial polyester-tiger composite microfiber has good antibacterial durability. The antibacterial polyester-tiger composite microfiber has good antibacterial and antibacterial durability and will expand the application range of ultrafine fibers.

 

Polyester microfiber unique to increase the difficulty of dyeing

Polyester microfiber is divided into three types: sea-island type, orange petal wire, and spun silk.

The most remarkable feature of polyester microfibers is that their single filament denier is much lower than that of ordinary fibers. The garments made of polyester microfibers are comfortable, beautiful, warm, and breathable, have good drape and fullness, and have obvious advantages in terms of hydrophobicity and antifouling properties.

Polyester microfibers will encounter many technical problems in the printing and dyeing process. Take the example of PET island ultrafine fiber imitation suede varieties. First, the dyeing depth is poor, because the surface area of island-type microfibers is larger than that of conventional polyester fibers. Times, resulting in a large amount of reflected light on the surface of the fiber, and the degree of the shade of the dyed fabric is related to the reflected light on the surface of the fiber, and the refracted light returned from the inside of the fiber to the outside. Therefore, in the same amount of dye, the island-in-the-sea microfiber is more conventional Polyester fiber has a much lighter color depth. The second is poor color fastness, which is also due to the fact that the surface area of ultrafine fibers is many times larger than that of conventional polyester fibers. In the case of the same amount of dye, the amount of dye per unit area is much lower. To achieve the same apparent depth, the dye Should also be increased by the same proportion, resulting in doubled growth of the amount of disperse dyes, the color fastness decreased significantly. Third, poor level dyeing, disperse dye uptake rate and fiber radius and surface area related to ultra-fine fibers because of the small linear density, surface area, dye adsorption rate, easy to produce uneven dyeing. These above-mentioned factors impose higher requirements on the technical level of dyestuff manufacturers and printing and dyeing enterprises of polyester microfiber fabrics.

Microfiber glasses cloth features and proper cleaning tips

Microfiber glasses cloth is woven by a special process, does not contain any chemical drugs, has strong water absorption, no water stains on the surface after wiping; feels smooth and soft and delicate, effectively removes grease, and grease. The protection of the mirror is not scratched; no color, no lint, no decay, repeated cleaning, long service life, and so on.

The microfiber glasses cloth is durable to wash, does not damage the surface of the object after wiping, has high water absorption and oil absorption, high cleaning power, delicate touch, and softness.

Microfiber glasses cloth is a high-grade clean cloth made of polyester/nylon double-component composite microfibers. The fineness of the monofilament is less than 0.2dtex, which is about one-tenth of the ordinary fiber fineness. This composite fiber passes special the textile, fiber-opening, and other processing processes that have created a capillary space effect between the fiber and the fiber. With a high fiber density, the contact surface of the wipe is also large.

It is important to clean the microfiber glasses cloth properly: (1) Do not iron and expose it. (2) Do not float or dry clean chlorine. (3) Do not use clean water above 60 degrees Celsius. (4) Do not use bleach, bleach will affect the wiping effect; shorten the life of easy-clean wipes. (5) Do not use softeners. The softener will leave a film on the surface, affecting the wiping effect and shortening the service life. (6) Do not use microfiber eyeglasses cloth and other clothes together with a washing machine to wash or dry, because the fabric will absorb the surface of the soft clothing and affect the wiping effect.

Microfiber Usage

The fabric made of it, after sanding, sanding, and other high-level finishing forms a layer of appearance resembling peach hair and is extremely bulky, soft, and smooth. The high-end fashion, jacket, and T made from this fabric are used. Cool and comfortable shirts, underwear, skirts, and other cool, sweat-absorbing is not personal, full of youthful beauty. 

Foreign use of microfiber as high-grade artificial suede, both similar to the appearance of the leather, feel, style, and low prices; due to ultra-absolute fiber Fine and soft, use it to make a clean cloth with excellent decontamination effect.

It can wipe various glasses, video equipment, and precision instruments without any damage to the mirror surface. Ultra-high-density fabrics with extremely smooth surfaces can also be made with microfibers. The use of sportswear such as skiing, ice skating, and swimming can reduce resistance and help athletes to create good results. In addition, microfibers can also be used in various fields such as filtration, medical care, and labor protection.

Microfiber bath towel cleaning methods

The material of the microfiber bath towel is different from that of other bath towels, so there are certain differences in the cleaning method. The cleaning of the microfiber bath towel can be washed with warm water without an irritating lotion. However, it must be cleaned after washing. Be careful not to use the bleaching powder, otherwise, the life of the microfiber bath towel will be reduced, and the softener will not be used. This will form a film on the surface of the bath towel, which will affect the comfort of contact with the skin. Finally, the microfiber bath towel can never be ironed and exposed.
