Update:27 Jul
⑴Super waterproof fabric
Ordinary raincoat can prevent the penetration of rainwater, but it is not conducive to the elimination of sweat and water vapor. The moisture-permeable and waterproof fabric changes this shortcoming. Using the large difference in the size of water vapor particles and raindrops, a porous structure film with a pore diameter smaller than raindrops is attached to the fabric surface, so that the raindrops cannot pass through, but water vapor and sweat It can pass smoothly and is conducive to ventilation.

The fabric is interwoven with a plain weave on a rapier loom. . The fabric is beautiful and charming. Compared with other cotton canvas, it has the common characteristics of softness, stiffness, breathability, easy washing, and comfort. It also has strong fastness, good drape, and strong antistatic properties that are unmatched by other fabrics. "Anti-static canvas" is mainly used to make petrochemical, liquefied gas station, gas station, oil tanker and other flammable and explosive occasions
Anti-static Zhigong cloth: This fabric is a new variety developed in 2005, and its sales performance has been not bad since its listing. It uses 32s / 2 cotton yarn for warp yarns; 32s / 2 cotton yarn for weft yarns; A special antistatic fiber, the fabric is interwoven on the rapier loom with a 3/1 tributary tissue, and the dyeing and finishing process is unique. The fabric surface is beautiful and charming. Compared with the cotton straight fabric, it has the common characteristics of softness, stiffness, breathability, easy washing, and comfort. It also has strong fastness, good drape, and strong antistatic properties that are unmatched by other fabrics.
⑸Insulation fabric
A kind of fabric using zirconium carbide compound particles added to nylon and polyester fibers to make it efficiently absorb solar energy and convert it into heat, that is, far-infrared thermal insulation fabric. Increased thermal insulation is of practical significance for clothing in cold environments.

(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.
