Fabrics That Make People Feel "Smooth, Breathable And Warm".

In the autumn and winter season, how to keep the underwear tight and comfortable under the condition of sports and leisure? The newly released Porel moisture and warm fabric of Nanjing Donghua Fiber Technology Development Co., Ltd. solves this problem.

The fabric can automatically adjust the balance between the body and the body, and achieve "dynamic and static conversion without changing clothes".

< /p >

< p > < strong > idea is between /strong and /p.

< p > to solve this problem, Cheng Guolei, general manager of Nanjing Donghua Fiber Technology Co., Ltd. first put forward the concept of "moisture permeability and warmth". Moisture permeability is good ventilation performance, and warmth reflects the active adjustment ability of material to liquid water and gaseous water.

< /p >

< p > Porel the advantages of moisture permeable and warm fabrics are based on the special structural properties of Porel fibers.

Porel fiber is a hydrophilic soft polyester hollow staple fiber in Donghua, Nanjing.

The fibers add hydrophilic groups and round waist cavities in the spinning process. The cavity structure not only plays a role of moisture permeability and permeability, but also can store heat and keep heat.

In addition, the Porel fiber has low modulus, low strength and low elongation. The fabric has excellent anti pilling properties, and its resistance to pilling is 3~4.

< p > "on this basis, through the communication with technical personnel of many well-known textile dyeing factories in China, combined with brand customer needs, materials and organizational structure have been designed and selected several times, and eventually developed this fabric."

Cheng Guolei said.

< p > breakthrough in the key technology development of the fabric, Han Qian, product development department of Nanjing Donghua Fiber Technology Co., Ltd., said: "we have made two relatively large attempts.

For the first time, it focused on making high elastic, windproof and heat resistant fabrics. Although the overall effect of the fabrics was good, too much emphasis was placed on high bullets, which resulted in high weight, and the fabric was not light enough; moreover, the characteristics of the knitted fabrics decided that without any finishing, it would not be able to achieve the effect of windbreak.

"Then we switched our thinking and started again, and designed functional design according to the characteristics of knitted fabrics, focusing on light weight, warmth retention, one-way moisture conduction and moisture permeability."

Han Qian said.

In order to achieve the movement of liquid water to guide the outside of the fabric, and to keep warm and breathable in the leisure state, the company's research and development team has also made a new round of material and organizational structure selection and development.

Through comprehensive testing of the 4 fabrics, the insulation rate, directional moisture conductivity and moisture permeability were detected, and the expected results were achieved.

When clothing is used for body wearing, the micro environment temperature and humidity formed between human skin and P are important indicators to measure human comfort.

People generally like to wear pure cotton clothing, because it has good moisture absorption and permeability, but in a state of sweat, cotton fabric is slow in moisture and clothes are glued to the body. It will bring humid heat in summer. It will bring wet and cold feeling in winter. It is not suitable for people to wear and wear when they are in frequent exchange state.

The key to the comfort of human clothing is the balance of moisture and heat. The common materials cause stuffy heat or wet cold sensation to the human body, mainly because they can not regulate the heat and moisture balance in real time.

< /p >

< p > the 3 kinds of materials of Porel moisture permeable and warm fabrics, conventional warm fabrics and pure cotton fabrics are the same as the organizational structure 250g/m2 < /p >

The comparison test of air permeability, directional moisture conductivity and insulation performance of fabric < < p > shows that Porel has the best directing moisture conductivity and moisture permeability of warm fabrics, and its air permeability is better than other chemical fiber fabrics, and its thermal insulation is better than that of similar cotton fabrics.

< /p >

< p > according to Cheng Guolei, in addition to testing the heat preservation rate of Porel moisture permeable and warm fabrics, it also increased the detection of its thermal resistance, moisture resistance and moisture permeability index (GB/T 11048 - 2008), moisture permeability and directional moisture conductivity (GB/T 21655.1 - 2008 GB/T 21655.2 - 2009). The results showed that the moisture permeability reached the standard (14200g/m2 24h) and the one-way pmission index reached the standard (5 grade).

< /p >

< p > moisture content is the test of the permeability of materials to water vapor, namely the detection of the permeability of materials; the greater the permeability, the better the permeability, the better the comfort of clothing. The popular saying is that the chemical fiber that the human body wears is less stuffy. Directional moisture conduction is the ability to pfer liquid water from one side of the material to the other side. The one-way pmission index indicates that the material has good one-way pmission capability to liquid water.

< /p >

"P >" these two indicators are passed, indicating that the fabric has good < a href= "http://www.91se91.com/news/index_c.asp" > damp heat regulation ability < /a >, it can actively adjust the balance of the body's heat and moisture, and the wearability of the fabric is very good.

Cheng Guolei said.

< /p >

< p > < < a href= > http://www.91se91.com/news/index_c.asp > > Porel > /a > the process of market acceptance of moisture permeable and warm fabrics is not smooth sailing. At the same time, it has also been questioned.

Cheng Guolei said.

< /p >

< p > Porel breathable and warm fabrics were tested for the first time with 4 fabrics. The test was based on the standard GB/T 21655.2 - 2009. The moisture permeability was tested. The contents of the wetting radius of the permeation surface, the diffusion velocity of the liquid water, the unidirectional pfer index and the comprehensive index of the dynamic delivery of the liquid water were tested respectively. Meanwhile, the insulation rate was tested according to the GB/T 11048 - 1989 (A method).

4 fabrics have a plain weave fabric weight of 225g/m2, although the indicators have passed the test, but at that time, customers have doubts about this fabric, feel that this fabric is simple in structure and light weight. For this reason, the company went to Jiangsu textile product quality supervision and Testing Institute for re examination. The results show that the fabric has good thermal insulation and one-way moisture conduction effect, eliminating the doubts of customers.

< /p >

< p > in order to prove the functionality of < a href= "http://www.91se91.com/news/index_c.asp" > fabric > /a >, a total of 25 people were found in Donghua, Nanjing. Among them, 15 were young, 5 were middle-aged and 5 were teenagers. For the different sports items, the fabric was made into clothing for free to these people.

In this way, a total of 20 days were followed up. The main items included skin comfort, skin drying, comfort and pilling.

The results of the survey showed that the fabric was highly evaluated by the pilot.

For example, several people who tried on the clothes were playing in the costume, and the feedback was: "the skin is dry and warm, and they do not feel the cold feeling of pure cotton fabric after exercise."

< /p >

< p > < strong > expectation, wider application scope < /strong > < /p >

< p > at present, the autumn winter cover series on the market tends to be light and warm, but mostly with cellulose fiber as the main body to ensure close fitting "breathability".

< /p >

"P >" and our Porel moisture permeable and warm fabrics can meet the comfort needs of different parts of the human body. Its organizational structure is diverse and can be made into sports underwear with breathable, breathable, unidirectional moisture and warmth. It can also be made into casual functional clothing.

Cheng Guolei said.

< /p >

< p > Porel moisture permeable and warm fabrics are mainly used in jacquard rib, cotton wool, Terry, jacquard double layer and other tissue structure products, which can be lightly brushed or sanded. The weight is between 200g/m2 and 250g/m2. Through the design of yarn and fabric structure, the products can be used for casual movement and clothing, such as student wear or soldier training clothes worn in autumn and winter.
