With the arrival of winter, the temperature decreases, the use of down jackets to keep warm, covering a very large area and population, each consumer has higher requirements for down jackets, the frequency of wearing, replacing, and nursing is gradually increasing, and consumers are constantly improving their requirements for down clothes washing, but there are still many questions about how to care for down clothes.
At present, the dryer and washing and drying machine on the market launch exclusive drying program or care program function, in order to effectively evaluate the drying effect of washing machine and dryer, this time our hospital in the industry for the first time proposed dryer and washing and drying machine "down fabric drying care" product certification. The certification adopts advanced theories in the field of textiles and microorganisms, puts forward a scientific evaluation system, and realizes the quantitative evaluation upgrade from sensibility to rationality for down drying. Through this certification, it is possible to evaluate the fluffy effect of down jackets after washing and drying, test whether the initial comfortable state is achieved after drying, and evaluate the removal effect of pathogenic microorganisms in down and mites that grow after seasonal storage. Technically, the down drying performance of drying clothing products has been refined, so as to distinguish the quality of down fabric drying care home appliance products on the market, and screen out high-performance home appliances, which provides an important reference for the objective and fair evaluation of down fabric drying care products. Through the evaluation test of this certification, it can also help consumers to scientifically choose dry clothing products and standardize the development of the industry.
Yue Jingsong, deputy chief engineer of the Testing Institute of china Household Electrical Appliances Research Institute
Yue Jingsong, deputy chief engineer of the China Household Electrical Appliances Research Institute Testing Institute, first introduced the background of the conference. Down is widely used in down jackets and other warm products because of its soft, light, fluffy, warm characteristics, when drying or storing, it will encounter drying and drying, producing odors; clumping, reducing the warm effect; salmonella, resulting in human infection diseases; after the change of season storage, air does not circulate and other reasons, breeding mites and other issues. To this end, Zhongjiayuan proposed the "down fabric drying care performance" product certification for the first time in the industry, and conducted quantitative evaluation from the aspects of appearance shaping, thermal insulation performance, special microorganisms, and reduction of allergy risk, and established a relatively complete evaluation system for down drying nursing performance. From the technical aspect of product publicity to form a binding effect, screening out high-performance home appliances, for the objective and fair evaluation of down fabric drying care products provide an important reference basis; at the same time to guide consumers to understand the principle of down drying care, scientific selection and purchase of drying home appliances.
Chen Lihua, Professor of fashion art and engineering school of Beijing Institute of Fashion
Chen Lihua, a professor at the School of Fashion Arts and Engineering of Beijing Institute of Fashion, introduced the characteristics of down, the factors affecting the warmth of down products, and the washing and drying care methods of down fabrics. Professor Chen put forward the factors affecting the warmth of down products through the interpretation of the types, composition structure and characteristics of down, mainly including the amount of down, the amount of filling and the fluffiness. According to the standard provisions of down clothing, the down jacket content should generally be ≥ 70%, and under certain conditions of filling, the higher the down content, the better the warmth. Within a certain range, the increase in pile filling and fluffiness will improve the warmth, but there is an optimal value. The washing of down fabric can be selected by hand or machine wash, and it is best to choose a washing machine with a down washing program when machine washing. Because down is easy to accumulate into pieces after washing, when using a dryer to dry down fabric, it helps to restore down fluffiness and improve drying uniformity by tumbling up and down and patting. In addition, the dryer takes less time to dry the down fabric, the clothes are cleaner and softer, and there are sterilization, mite removal, odor removal effects, more beneficial to health.
Liang Zhiyong, project engineer of zhongjiayuan (Beijing) testing and certification co., ltd. health home appliance testing center
Liang Zhiyong, project engineer of the Health Home Appliance Testing Center of Zhongjiayuan (Beijing) Testing and Certification Co., Ltd., introduced the relevant contents of CHCT-02-125-2021 "Implementation Rules for Down Fabric Drying Care Performance Certification", including certification mode, certification conditions, certification unit division and other aspects. In addition, the test items and technical requirements in CHCT-JSGF-116-2021 "Technical Specification for Evaluation of Down Down Fabric Drying Care Performance" were also introduced. Among them, the technical requirements of fabric performance include fluffy performance and thermal insulation performance (the fluffiness ratio limit is ≥0.90, the relative change rate of thermal resistance is ≤17%), and the technical requirements of microorganisms include sterilization performance and mite removal performance (sterilization rate ≥ 99.9%, mite removal rate ≥90%). The first batch of nine models that have passed the "down fabric drying care" certification have four brands and nine models, and their related performances have met the above requirements.
When the dryer is selected, it can be selected to have multiple filters, with better filtration efficiency, to avoid evaporator pollution; the inner cylinder can be reversed and reversed, not only reducing winding, large parts can also be evenly dried; because the filter wind blockage, forward and reverse reduce efficiency, in order to improve the drying rate, you can choose a large air volume dryer; with a low temperature drying control design, to avoid damage to special fabrics due to excessive temperature. According to their own needs, choose a dryer with special fabric drying functions (down jacket, wool, silk, special fabrics for storm jackets), fabric care functions (wrinkle removal, odor removal, dust removal, hair removal, fluff), health and health functions (sterilization, mite removal, allergen removal, bacteriostatic, self-cleaning).
Song Jingxue, Director of the Research Department of the National Household Appliances Industry Information Center
Song Jingxue, director of the Research Department of the National Household Appliance Industry Information Center, pointed out that in the past year, clothes dryers have led the sales of major appliances. According to data, the domestic sales scale of major appliances will continue to expand in 2021, of which the retail sales of clothes dryers will reach 4.9 billion yuan, with a year-on-year growth rate of 73.8%, much higher than other categories. Dry clothing home appliances have attracted more attention from consumers, and the market has maintained a high-speed growth trend. With the macroeconomic stabilization, the continuous recovery of residents' income and consumption expenditure, prompting consumers to purchase high-end products such as "dryers" to strengthen, enterprises have also laid out high-end markets, in 2021, the share of drying machine heat pump condensation accounted for 98.3%, the average price increased from 7716 yuan to 8364 yuan, and the proportion of dryer products above 8000+ increased by 10.4%. In the past three years, the share of washing and drying integrated drum machines in the washing machine category has increased year by year, and consumer demand for drying has gradually increased; the type of dryer has steadily changed to the heat pump condensing type; the capacity is also developing to large capacity, with 10-12kg accounting for 42.9%. Dryer can provide rapid drying, sterilization and sterilization, mite removal, fluffy and comfortable effect, sterilization function of the dryer in the sterilization + mite removal multiple functions of transformation, and for different clothes and clothing, drying program is constantly enriched, to bring consumers a more comfortable and quality of life. In 2022, due to the normalization of the epidemic, consumers pay attention to health, quality of life needs, drying pain points are dominant, the amount of ownership is low, the scale has room to rise, there are many participating brands, enterprises to promote the market and other reasons, clothes dryers will still maintain rapid growth, and the market size is predicted to reach 5.9 billion yuan, an increase of 20.7% year-on-year.
