Analysis On The Stability And Warmth Retention Of Multi-component Mixing Down

There are two ways for Down to be a warm material. One is as a filler material to manufacture jackets, duvets, feather products, which has advantages like light, soft, warm. But there are also a lot of Disadvantages on the feather products:①it is higher standards for feather used as fill material, otherwise the drill down is very serious;②stuffed down products are generally used in high-density coated fabrics, most of such fabrics are synthetic fabrics, wear an electrostatic phenomenon seriously in winter③stuffed down products volume, bloated, convenient to carry and store. Another warm down feather material is processed into a Flocculant felt, wadding felt that acupuncture may be laminated or a comb type pattern in the process in the mixed amount of the binder fibers in the raw material, after drying oven, the binder fiber wadding felt bonded together to form a unitary feather warm layer. The advantage of this warm down material are:①Light, soft, warm and good;②Not bloated, very convenient to carry and storage;③Drilling velvet phenomenon significantly reduced, therefore it is not used as filler fabric requirements so high, in addition to You can use coated synthetic fabric, but also some cotton or wool fabric density, thus improving the wearability of down products.A common drawback of down material is resistant to insects and mildew, the need to use insect repellent during storage; the common advantage is soft, light and comfortable to wear.The issue is proposed by Tung Lung down products company of shanghai, the analysis on stability and thermal of multi-component mixing down and developing several new hybrid wadding that both with high natural feather body and warmth rate, resilience, overcoming its defects like easily glide and easily drill down, discussing flakes production process so that it can meet the operability and innovative.Firstly, Selecting a representative of the high thermal fiber in the popular market, Then making a measure to compare their morphology and mechanical friction properties, Selecting the most appropriate five kinds as with down blend fibers;Then, blending with a certain percentage range down, in order to obtain both morphological stability without loss of warmth and can make good stability interpenetrating fibers, constantly optimizing the process and adjust the mixing ratio, with warm, compression elasticity, anti-felt resistance, stability wadding used to evaluate the performance of the new, ultimately determining the optimal mix of fiber types and the optimal ratio of programs;Finally, These studies can be obtained by the following conclusions:(1) According to the fiber morphology measurement and analysis, The morphology and cattail down is similar to the other four fibers that have a greater length and curling. From the analysis of the mechanical properties of the fibers, the modulus comparison shows:EPE> Camel> rabbit> Polyester; Unequal weights comparison shows:Polyester> Camel> EPE> rabbit. From the analysis, the nature of fiber friction, friction properties camel hair fibers better than rabbit.(2) the ratio of compression resilient with complex cattail fiber increases, wadding resilience decreases, while the other four kinds of fiber with its complex ratio increases, the resilience showed an increasing trend, which with its high curl-related; anti-compounding proportion felt resistance decreases with increasing ratio of fiber, and fiber entanglement between each other which is not conducive to anti-felt resistance related; morphological stability: With the ratio of the proportion of fiber complex the enhancement increases.Thus the optimum combination of properties available4each main complex with fiber ratio, respectively:35%cattail,50%camel hair, angora40%, polyester is30%, EPE is30%, while the secondary ES fiber with a fiber content of10%.(3) the performance of the five kinds of four mixed feather fiber main body comprehensive comparative analysis of the merits of sorting performance in four other weight criteria are:Camel> Polyester> EPE> rabbit> cattail best program is down40%+50%+ES camel hair fibers10percent; If unequal weights (warm30%:3%of the morphological stability:resilience2%:Anti felt resistance2%) under the conditions, the optimal Sort results remains:camel (points)>polyester (3.7)> EPE (3.1points)> rabbit (2.6)> cattail (1.6points).(4) Corresponding to hand mixing fibers and mixed fibers ES (?) machine opening, blending and mixing down the fiber manually (?) Stir spray antistatic agent, place (24h)(?) small (?) carding opener air laid mixture (?) hot melt adhesive reinforcement forming, which is more suitable for this kind flakes production process down.
