4 Properties 1.Moisture Transfer PP is the least absorbent of the textile fibers. It does not wet out. In fact, PP “adsorb” water, moving moisture in the vapor stage to the outside of the fabric, never holding any moisture. An added benefit is the breathablility of PP. The moisture moves away from the skin in the vapor stage, before it has condensed on the skin. Condensation on the skin gives rise to a feeling of clamminess. 2.Quick Dry Because PP does not absorb moisture into the fiber, drying time is minimal. The fabric will dry while you wear it.
5 3.Lightweight PP is the lightest of all apparel fibers and is lighter than water. It is 30% lighter than polyester, and 20% lighter than nylon. Regardless of the activity, weight saved means energy is saved for improved performance. You get more bulk and warmth for less weight. 4.Thermal Conductivity PP possesses the lowest thermal conductivity of any natural or synthetic fiber. This means that more heat is retained for a longer length of time. The wearer stays warmer longer. The insulation factor is greater by weight for PP than other fiber.
6 5.Chemical Resistant PP will not react to ordinary chemicals or degrade due to sweat and body salts. Therefore, if washed with bleach or harsh detergents, polyolefin will not break down. 6.No Odor Retention PP is non-absorbent. It is hydrophobic, so bacteria and mold can not survive on the non-moisture surface of the DreamFel® fabric. A garment that is washed regularly in hot or warm water with detergent will not retain body odors. Note that the PP is lipophilic; therefore, when you wear PP clothes for several days without washing your body, the body oil will generate smell of the grease which will stick on PP surface, but it can be washed.
7 7.Colorfastness PP is precolored in the liquid stage so the color in the fiber is part of the fiber itself. Why is this significant? PP will hold color longer than other fibers. During outdoor activities, washing or wear and tear your garment stays looking newer longer. Who said outdoor enthusiasts don’t want to look good? 8.Abrasion Resistant PP is a durable fiber, and will withstand a lot of wear and tear. This will help preserve those pressure points where clothing tends to wear, like in the seat.
8 9.Environmentally Polymerization process ： saving energy PP belong to polyaddition, it can release heat. Spinning process ： low energy exhaust The spinning temperature of PP is lower than polyester and nylon. The waste yarn can be respinning. There is no waste yarn in spinning process. Dying and finishing process ： Because PP can’t be dyed, water is no wasted. Throwing away problem ： 1.100% PP can be recycled easily. 2.The harmlessness of this material is approved by FDA & Oeko-Tex Standard 100 class 1 for baby articles. 3.It does not produce any toxic gas or harmful by-products. 4.After throwing away, PP will degrade by sunlight in half year. ※ DATA SOURCE : INNOVA

34 Applications 1.Thermalwear(underwear) 、 Skiwear Heat Retention:PP has the lowest thermal conductivity rating of all natural and synthetic fibers. Thermal conductivity is the rate at which a substance loses heat. Because of PP's low rating, more heat is retained than any other natural or synthetic fiber. PP is even warmer than wool. PP is specified by the U. S. Military for Extended Cold Weather Clothing System (ECWCS). ECWCS is a five layer clothing system for military use in extreme environments such as Alaska and Bosnia. A PP brushed fleece garment is the first thermal layer, the skin contact layer, of the ECWCS system. PP is soft to the touch and comfortable to wear. PP Tg point is between -15 to -20 ℃. In a polar environment, compare to the other fibers, it will not become hard and brittle.

38 2.Dive and Surf In many cases an PP wetsuit can delay the need for a neoprene wetsuit until later in the season. PP retains body heat and is less cumbersome and more comfortable than neoprene. The spandex in conjunction with the PP gives complete freedom of movement. For warm weather diving, the suit insulates the body as water temperatures vary by depth and time of day. For cold weather diving when added protection is needed, an PP wetsuit serves as a neoprene liner which a) eases the diver in and out of the cunbersome neoprene bodysuit, and b) adds another layer of insulation to retain body heat. PP is diving gear which is used year round. PP does not absorb water, therefore the divingsuit will dry rapidly out of the water. For surfing, PP is used again as a seasonal replacement for neoprene in both surf and rashguards. Again, it is an insulating fiber to keep the surfer comfortable as he/she goes in and out of the water. Protection from the sun, jelly fish and sharp coral.

46 Technology of PP Moisture Management Dry layer ： 1.Against your skin, sweat or moisture transfers to the wicking layer. 2.It can be the hydrophobic fiber (ex.PP) or special cross section fiber(ex.CoolMax). Wicking layer ： 1.It wicks the sweat or moisture from the dry layer to outside of fabric. 2.It can be the hydrophilic fiber (ex.cotton,rayon) or high count filament.
47 Dry Test 1 2 3 4 1.Water dropped on the white skin-side of the fabric quickly slides vertically through the PP and spreads horizontally across the darker wicking layer. 2.The fabric s pressed forcefully between two layers of absorbent brown paper towel to demonstrate how the moisture moves to the face of the garment, away from the skin. 3.The white PP side leaves no moisture on the paper towel. The water exits through the spaces in the PP layer and is not absorbed into the yarn. 4.Notice the difference in the dryness on the paper towel. The PP side of the fabric absorbs all of the moisture. → Which side would you rather have against your skin? ※ DATA SOURCE ： TRANSPOR
48 Characteristic of PP Moisture Management DreamFel ® is not coating by wicking agent, it is permanent and lasts up to 100 washes. PP compared with CoolMax ： CoolMax is a polyester yarn made with external channels that move moisture. CoolMax wicks moisture and repels moisture. Once the fabric reaches its saturation point, the spaces between the yarns close and moisture transference and evaporation slows down. PP fabrics go beyond wicking because the PP dry layer is built right in, next to the skin and does not absorb moisture. In effect, the dry layer acts like a “second layer of skin”, allowing moisture and vapor to exit through the spaces in the fabric without saturation – you stay drier longer and dry faster. DreamFel ® can keep you both cooler and warmer.
49 Compare with Cotton Cellulosic fiber ： Cellulosic fibers like cotton and rayon feel great against the skin when dry. Cotton-rich fabrics have to many OHs, therefore they absorb and hold to much moisture. As a result, there is a breakdown in the moisture transport; the fabric becomes saturated and the microclimate between skin and fabric becomes hot and sweaty. Moisture management fabric ： The moisture management technology moves moisture quickly from the skin through the fabric and into the air.
50 Design of PP Thermalwear Helly Hansen 3-Layer Weather System ： 1.Inner Layer ： LIFA Bodywear LIFA bodywear, made 100% Polypropylene, serves a dual purpose of moisture management and insulation. Using the body’s own heat, LIFA acts as a transport agent to perspiration,moving moisture to the next layer of clothing and away from your skin so that you always feel dry and comfortable. 2.Insulating Layer ： Helly Hansen PROPILE/PILE The knitted fabric absorbs minimal moisture and has the unique capability of collecting and keeping the warmth while transporting moisture away from the body. 3.Protective Outer Layer ： HELLY-TECH Windproof, waterproof and breathable fabrics give protection against changing weather. ※ DATA SOURCE : HELLY HANSEN
51 Notice Iron free, because of low melting point. The temperature of dry heat set can’t over 120 ℃, but PP and PET blend fabrics can dye in 130 ℃ hot water. Don’t use mineral oil base lubricant, because mineral oil will damage PP. Don’t dry clean. Different end use utilizes different softening agent ： a.If the function of fabric is moisture management, then adding the hydrophilic softening agent. b.If the function of fabric is water repellent, then adding the hydrophobic softening agent.
52 Poor adhesion to glues and latex, because of none functional group. Flammable which melts and burns like wax. If necessary, it must be adding the flame retardant. Poor UV and thermal stability requires addition of UV stabilizers and antioxidants – when the PP fabrics is used as outdoor, just like car seat, beach umbrella, beach chair.
