Filling material with PET and PTT composite filament as raw materials and manufacturing method thereof

Abstract

The invention discloses a filling material with PET and PTT composite filament as raw materials and a manufacturing method. The down jacket and the cold protective clothing adopting the filling material are low in cost, good in heat insulation performance and free of odor. At the moment, the PET and PTT composite filament fiber are curly and have elasticity, and the stable filling material with good quality is obtained. The filling material includes the PET and PTT composite filament fiber and mixed fiber components which are mixed, then opened or pelletized to make the filling material. The content of the PET and PTT composite filament fiber is larger than 0 and smaller than 100%. The content of the mixed fiber components is larger than or equal to 0 and smaller than 100%. The manufacturing method of the filling material is further disclosed and includes the following steps of (1) mixing, (2) cotton feeding; (3) opening and (4) pelletizing.

Description

technical field [0001] The invention relates to a filling material and a preparation method thereof, which are used for filling cold-proof clothing and down jackets. Background technique [0002] Most of the filling materials of common cold-proof clothes and down jackets at present adopt materials such as down or polyester hollow, microfiber. [0003] Down is the light and fluffy natural filling in the world. Down has a star-shaped structure. There are countless small spaces in the down silk, which can contain a lot of air. Therefore, it is soft, warm, fluffy and good elasticity. It is very suitable for As a filler for cold-proof clothing, the disadvantage of down is that it is the feathers of artificially raised animals, so there may be some natural microorganisms or odors, some odors will appear after a long time, children and other individuals may have allergies, etc. Moreover, as a filler, there is the case of drill down, that is, some down will run out from the gap bet...

[0003] Down is the light and fluffy natural filling in the world. Down has a star-shaped structure. There are countless small spaces in the down silk, which can contain a lot of air. Therefore, it is soft, warm, fluffy and good elasticity. It is very suitable for As a filler for cold-proof clothing, the disadvantage of down is that it is the feathers of artificially raised animals, so there may be some natural microorganisms or odors, some odors will appear after a long time, children and other individuals may have allergies, etc. Moreover, as a filler, there is the case of drill down, that is, some down will run out from the gap between the sewing lines of the fabric, and it is not washable, and it is prone to agglomeration and deviation after washing, and the price of down is very high, and the price of good down It can be around 500,000-600,000 yuan

[0004] Polyester hollow fiber and superfine fiber are some special fibers processed by machinery. For example, the section of hollow fiber is hollow, and the fiber is three-dimensional curled. The air layer inside the fiber blocks the loss of body temperature, so that the skin surface temperature It will be lost quickly due to the harsh external weather, and achieve the function of heat preservation. The microfiber produces softness through the fineness of the fiber. Polyester hollow or microfiber is used to imitate the state of down to achieve warmth, fluffy, rebound and other properties. , since the state of polyester fiber is machined the day after tomorrow, the disadvantage is that there is a big gap in various properties compared with down, and the washing performance is worse, and the performance drops by more than 30% after washing and before washing.
