Research And Development Of New Needling Insulation Warm Flocculus

With the development and application of a variety of high-tech increasingly promoted in the textile industry, it makes the warm materials toward increasingly complex multi-direction.By using the acupuncture method woven nonwovens will eliminate harmful substances that, the way the production does not produce harmful substances, and the process is simple, short process, lower cost even more environmentally friendly.The new type of thermal fiber(with bamboo fiber, three-dimensional hollow polyester fiber, Viloft fiber, etc.) used in non-woven warm flakes of research and development,and reasonable to add steel fiber and other functional fibers,by using the absorption and desorption capabilities,natural antibacterial,biodegradable of bamboo charcoal fiber moisture,Three-dimensional hollow polyester excellent thermal performance,Good air permeability excellent moisture wicking properties and adjust performance of Viloft fibers and the excellent antistatic properties of stainless steel fibers, and so on.Developing the environmentally friendly non-woven winter clothes, blankets and other warm with flakes, and after finishing to achieve multi-functional requirements. Density needlepunched needling depth and material selection up to determine the process,which needling density is 80-120 stab / cm2, needling depth of 6-10 mm. And determine the influence of each parameter on the new needling insulation flocculus factors thermal performance flakes.In order to expand the scope of application of the product,we will develop 11 new acupuncture warm flakes,1-5 warm flakes which is far-infrared functional fiber thermal flakes, to identify changes between warm flakes by changing the process parameters;6-8 are the same process parameters, acupuncture warm flakes of different materials, the use of warm needling flakes fiber to understand changes through changes;9-11 are the stainless steel fibers containing antistatic acupuncture warm flakes, antistatic properties to determine changes in the amount of change through the stainless steel fibers, so that in addition to having the thermal performance also has anti-static properties, used in fire in the field of clothing.After weaving, testing the 11 kinds of new acupuncture warm flakes performance, including quantitative、thickness、permeability、bulkiness、compressibility、recovery rate 、 heat rate and strength tests to compare differences in their performance.Using the SPSS software for data analysis, getting the relationship between a certain number. Using fuzzy comprehensive evaluation method to identify the optimal warm acupuncture for three-dimensional hollow polyester flakes are woven acupuncture warm flakes,Its technology is needling density of 100 stab / cm2, needling depth of 8mm.Selection nanometer far- infrared finishing agent for the three-dimensional hollow polyester woven acupuncture warm far-infrared nano flakes finishing, so that it has some health, better applied to life.By correlating available with single-factor test to test analysis the nano far-infrared finishing agent concentration ratio of 3%, 4%, 5%;Bath temperature was set at 40 ℃, 50 ℃, 60 ℃;The immersion time is set to 15 min, 20 min, 25 min.Testing the nano far- infrared fabric finishing performance, including testing insulation, permeability, infrared emissivity.Getting the best finishing process for the nano far-infrared finishing agent concentration is 4%,water bath temperature is 60℃,the immersion time is 25 min.After nano far infrared fabric finishing, thermal insulation was significantly improved,but the permeability has not been greatly affected.
