Abstract
The invention discloses a method for producing far-infrared chinlon short fiber. The method comprises the following steps: 1) heating chinlon sections to a molten state, adding far-infrared ceramic particles and nitrocellulose, commixing, and pelleting so as to obtain master batch; 2) spinning the master batch, washing yarns, drying, and winding, thereby obtaining the far-infrared chinlon short fiber. Compared with the prior art, the raw materials and processes are improved, so that the tensile strength of the product can be greater than or equal to 120Mpa, and the bending resistance can be greater than or equal to 150Mpa.
Description
Technical field
The present invention relates to the production method of a kind of far infrared polyamide staple fibre, belong to field of new.
Background technology
Chinlon is the trade name of Fypro, also known as nylon (Nylon).English name Polyamide (is called for short PA), and its basic component is the fatty polyamide coupled together by amido link.
Chinese patent 201110451844.4 provides the production method of a kind of far infrared chinlon filament, comprises the following steps: 1) prepare far infrared chinlon master batch: by blended to slices of caprone, ceramic particle and dispersant pelletize, obtain far infrared chinlon master batch；2) spinning: by step 1) in the far infrared chinlon master batch made and chinlon 6 section co-blended spinning, through the winding that oils, balance and stretching, obtain far infrared chinlon filament.But, polyamide staple fibre adds far-infrared ceramic particle, its hot strength and bending strength will decline to a great extent, and cause that toughness of products is deteriorated.
Summary of the invention
The technical problem to be solved in the present invention is to provide the production method of a kind of far infrared polyamide staple fibre.
In order to achieve the above object, the technical scheme is that the production method of a kind of far infrared polyamide staple fibre, comprise the steps:
1) being heated being warming up to molten state by slices of caprone, then add far-infrared ceramic particle and celluloid, blended pelletize obtains master batch；
2) master batch is carried out spinning, spinning is carried out, dries, winds, obtain far infrared polyamide staple fibre.
Further, step 1) in, it is heated to 320 DEG C.
Further, step 2) in, adopt wet spinning that material solution is carried out spinning.
Further, the temperature of described wet spinning controls at 215-245 DEG C.
Further, step 2) in, utilize deionized water that spinning is carried out.
Further, step 2) in, winding speed is 25-165m/min.
Further, far-infrared ceramic particle addition is the 3～5% of slices of caprone weight, and celluloid addition is the 5～7% of slices of caprone weight.
Compared with prior art, the present invention is by making the hot strength of product reach more than 120Mpa the improvement of raw material and technique, and bending strength reaches more than 150Mpa.
