Product Description:

Specification of Hygroscopic Calorific Fiber:

- Heat insulation fiber when wearing
- Quick dry and feel comfortable
- Remove hot and feel relaxed
- Environmental protection and health
- No poison to human body
- No pollution to the environment

Cold-proof and keep warm is the important comfort index of winter clothing,the traditional heat preservation method is usually control caused by heat conduction, convection and radiation heat loss.Such as using the thick fabric or cotton wool to insulation, some still use metal coating fabrics.   

However, the requirement of modern people for clothing comfort, functionality and aesthetics is higher and higher,the traditional warm clothes fluffy and bloated,neither convenient for activities as well as affect beautiful.With the rapid development of science and technology and the continuous improvement of people's living standard,the requirement of people for the fabrics and clothing’s practical function tend to diversification.So,the development for the actively adopt heat of heat preservation material have the important significance.Fever fiber: including Hygroscopic Calorific,Electricity Heating,Infrared Heating,Solar Heating,PCM Heat Release,Chemical Heat Release etc,all are actively adopt heat of heat preservation material.     

Japan's hygroscopic calorific fiber research more mature,the hygroscopic calorific fiber working principle: the liquid water evaporation need a great deal of vaporization heat,in contrast,the gaseous water molecules turn into the liquid water also will produce agglutination heat.And according to the test data show,when the person is motionless,the outward evaporation of moisture through the skin about 15 g / •h;In sports,there are a lot of sweat,both liquid and gas state,the quantity is about 100 g / •h.Therefore,the human body even if don't exercise also has a lot of sweat evaporate.Hygroscopic calorific fiber exactly use the water of gas and liquid variation,used to keep warm through the heat generated by changing the human body generated khan gas into liquid.  

But this kind of hygroscopic calorific fiber’s effect of heat preservation and thermal durability also have flaw,so this kind of fiber market promotion was limited.Such as hygroscopic calorific underwear,this kind of underwear’s hygroscopic calorific fiber material is expensive,general warm underwear was made by a small amount of calorific fiber with other fibers.Therefore,even if the real warm underwear,its temperature rise could not very high.   

Phase Change Material Hygroscopic Calorific Fiber

However our company developed hygroscopic calorific microcapsule,no matter on the effect of heat preservation or thermal durability have been greatly improved.This kind of brand-new hygroscopic calorific microcapsule has excellent hygroscopic calorific and humidity regulating function.  

The hygroscopic calorific fiber’s characteristics: 1. Heat insulation fiber when wearing. The hygroscopic calorific microcapsule play to maximum performance,it contains the hydrophilic polymer materials can effectively absorb the skin evaporation of water vapor,and convert into heat energy,persistent stay warm. 2. Quick dry and feel comfortable. The polymer material can absorb and transform the sweat quickly,let the clothes become dry. 3. Remove hot and feel relaxed. Excess heat cause to stuffy feeling is a very difficult problem,keep the comfortable dress sense in the cold days,required to maintain appropriate humidity between underwear and skin.The hygroscopic calorific microcapsule’s humidity regulating function can remove redundant moisture,convert sweat rapidly and keep dry and warm feeling. 4. Environmental protection and health,no poison to human body,no pollution to the environment.

Q:What are the new energy products
Solar products: solar street lights, solar water heaters, etc.Nuclear energy: nuclear powerOcean Energy: wave power, tidal powerWind power: wind powerBiomass: made of liquid or gaseous fuels
Q:What is the energy consumption per unit product
Formula: (1) comprehensive energy per unit of product yield comprehensive energy consumption per unit of product yield consumption = production of comprehensive energy consumption of the product (equivalent) / qualified product yield (2) yield of single unit product energy consumption per unit of product yield of single energy consumption = production of the product consumption of a variety of energy the number of qualified products yield (3) than the unit energy consumption of products according to the standard procedure to calculate the energy consumption than the unit energy consumption = comprehensive energy consumption according to the standard calculation of the amount of qualified production process / product yield can be calculated according to the standard energy consumption than single bit = yield statistics method of comprehensive energy consumption volume / year range: standard products report on the production of major products for the annual energy consumption of 5000 tons of standard coal and above the legal unit. The index of the sub item is the production of a product of a number of varieties of the total energy consumption of energy, not including production has nothing to do with the amount of energy for the purpose of life, nor does it include internal recycling energy and enterprise basic construction unit consumption using waste heat and gas; mother is qualified, have procedures for storage products production.
Q:Coal washing products are primary energy, or the two energy?
Based on this, I think it is wrong to put the coal washing products (washed coal, washed coal, washed coal, etc.) as the two energy. This is because the coal washing and processing is different from the general primary energy products to secondary energy products. Coal is mainly through jigging and flotation process will be different, the proportion of the physical size of the coal area separated from the mixed gangue in the coal removed
Q:What are the types of new energy vehicles
1, fuel cell electric vehicle (FCEV):The utility model relates to a motor which is driven by a chemical reaction, and is driven by a motor. The energy of the battery is directly converted into electricity by the chemical action of hydrogen and oxygen, rather than by combustion.
Q:New energy (photovoltaic products) now foreign trade market?
Because of the decline in the cost of photovoltaic, trade stocks are devalued. Which buyers and sellers do not want to bypass the two dealers
Q:Rapid rise in petrochemical products and energy prices
Dependence on petrochemical products is not large, traditional Chinese medicine and Chinese herbal medicine mainly as raw materials
Q:What are the tax policies for renewable energy companies?
The national development and Reform Commission had issued the "renewable energy and long-term development plan" put forward, to 2020 the proportion of renewable energy in the energy structure to reach 16%, the proportion is still less than 1%. plan to increase financial input, the implementation of preferential tax policies "set down as a principle of the development and utilization of renewable energy.
Q:Metro energy feedback products which good?
Then the annual cost savings of 4.86x350x365=620865 yuan. If you are interested in further understanding can be concerned about Sheng Hong electric WeChat public number in the above there are a lot of introduction of the article, you can also direct contact 0755-86511588, will be a detailed answer
Q:Which products need to be marked energy efficiency logo
Energy efficiency standards and energy efficiency labeling has been shown to be the best way to reduce energy costs in terms of cost-effectiveness, but also will bring huge environmental benefits, but also provide consumers with a positive return. Recent research results show that the formulation and effective implementation of new energy efficiency standards and energy identification, increase the efficiency and the level of consumer awareness of energy saving, energy saving in 2020 will be approximately equivalent to 277.5TWh, energy saving 1.29 tons of standard coal. The two common electricity savings equivalent to 2020 China urban and rural residents is expected to 56% of total electricity consumption, that is, through the development and promotion of energy efficiency standards, the implementation of energy efficiency labeling, China future 20 years of urban and rural residents can use the expected growth of consumption by nearly 85%. To 2020, the implementation of energy efficiency standards and labels will total 1.10 reduction in carbon emissions million tons; emissions of nitrogen oxides will reach more than 1 million 700 thousand tons; sulfur oxide emissions will reach 18 million 330 thousand tons; atmospheric particulate emissions will reach 10 million 350 thousand tons. The significant reduction in emissions of atmospheric pollutants can greatly alleviate the environmental problems such as greenhouse effect, photochemical smog, acid rain, and so on.
Q:Definition of low carbon energy
All of these need to implement low-carbon industrial system in Western europe. It includes thermal power emission reduction, new energy vehicles, building energy efficiency, industrial energy conservation and emission reduction, recycling economy, recycling of resources, environmental protection equipment, energy-saving materials, etc.. We are now in an important period of economic transformation.
