Chemical fiber cotton fiber filling material and manufacturing method thereof

Abstract

The invention discloses a chemical fiber cotton fiber filling material and a manufacturing method thereof. The chemical fiber cotton fiber filling material replaces down feather to fill down feather products, and comprises at least 70 to 99 wt% of chemical fiber material and 1 to 30 wt% of natural fiber material. The chemical fiber material comprises at least one or more chemical fiber resin cotton of the above specification, the natural fiber material is a natural fiber made from a natural down material, and the fiber length of the natural fiber material is less than 3 cm.

Description

technical field [0001] The invention relates to a chemical fiber cotton (velvet-like) filling material, in particular to a chemical fiber cotton filling material that is lightweight, washable without tangling, and has excellent heat retention and a manufacturing method thereof. Background technique [0002] Natural down products, such as down jackets, duvets, sleeping bags, etc., have the effects of lightness and warmth. Most of the raw materials used are the down of waterfowl such as geese or ducks, which are highly water-repellent, washable, and fluffy. My favorite product to keep out the cold; however, the production of natural down products is limited and the cost is high. Most of the products currently on the market are mixed with an appropriate proportion of chemical fiber (man-made fiber) components to reduce production costs as much as possible while maintaining considerable functionality. , but the amount of natural down content in the product still has a certain pr...

Problems solved by technology

[0002] Natural down products, such as down jackets, duvets, sleeping bags, etc., have the effects of lightness and warmth. Most of the raw materials used are the down of waterfowl such as geese or ducks, which are highly water-repellent, washable, and fluffy. My favorite product to keep out the cold; however, the production of natural down products is limited and the cost is high. Most of the products currently on the market are mixed with an appropriate proportion of chemical fiber (man-made fiber) components to reduce production costs as much as possible while maintaining considerable functionality. , but the amount of natural down content in the product still has a certain proportional relationship with the functional price

[0003] There are also products filled with purified fiber. Although the cost is low and the price is cheap, it can be widely used, but the bulkiness is insufficient. Based on the basic demand for warmth, the filling density of chemical fiber materials is usually more than 2 to 2.5 times that of natural down (general chemical fiber filling density About 200G / M 2 Above, the filling density of pure natural down is about 80G / M 2 above), but cannot meet the requirements of lightweight; in addition, after washing general chemical fiber products, the fiber groups tend to tangle into agglomerates, which leads to problems such as reduced warmth retention and unusable products for a long time.
