Preparation method of synthetic fiber wig

Abstract

The invention discloses a preparation method of synthetic fiber wig. According to the preparation method, the following processes are adopted: firstly, phase change energy storing materials are melted and are then added into natural high molecular raw liquid or fiber forming polymer raw liquid for emulsification, then, a solution spinning method is adopted, primary wig fiber with the diameter being 20 to 200mum is prepared and is sequentially treated through organic silicon finishing agent emulsion soaking, soaking rolling and baking processes, films are formed on the surfaces of the wig fiber through self cross linking, or films are formed through reaction with groups in the wig fiber, and the synthetic fiber wig with heat storage and temperature regulating functions is prepared. The phase change temperature range of the phase change energy storing materials is 30 to 38 DEG C, in addition, and the heat enthalpy value is not lower than 100J / g; the organic silicon finishing agent emulsion is poly(dimethyl) siloxane micro emulsion with more than one different modification groups, and in addition, the mass percentage of the organic silicon finishing agents in the organic silicon finishing agent emulsion is 1 to 50 percent; and the diameter of the synthetic fiber wig is 20 to 200mum.

Description

technical field

[0001] The invention relates to a synthetic fiber wig manufacturing technology, in particular to a method for preparing a synthetic fiber wig with a phase-change energy storage material as a modified component. Background technique

[0002] Generally speaking, the materials used for wigs are mainly made of natural materials such as human hair and animal hair, as well as thicker synthetic fibers. Wigs made of natural materials such as human hair are high-grade, but they are currently facing a shortage of raw materials and are expensive. However, wigs made of synthetic fibers such as polyester fibers, polyamide fibers, polypropylene fibers, and polyvinyl chloride fibers have poor hand feel, luster, and usability, and are low-grade products. Research on improving the grade of synthetic fiber wigs by adding different functional fillers has been going on.

[0017] The synthetic fiber wig with the function of heat storage and temperature adjustment can be prepared by using the preparation method of the invention, the preparation process is relatively simple, and it is suitable for industrial production. Since the wig fiber uses phase-change energy storage materials as additives, it can automatically absorb and release heat at the appropriate temperature of the head, so that the internal temperature of the wig is relatively constant, and the comfort of the wig is greatly improved (generally maintained within 3 to 5 hours). Comfort) and hygiene, improve the grade and quality of synthetic fiber wigs. The hair cover can be washed and combed repeatedly. At the same time, some wigs treated with silicone finishing agents also have flame retardant properties, and at the same time have the characteristics of softness, smoothness, wear resistance, antifouling and strong hair feel.

Embodiment 1

[0021] Add 500g compound emulsifier (225g Span-80 and 275g Tween-80) into the N, N-dimethylformamide solution containing 8kg 20wt% polyacrylonitrile and mix uniformly to obtain system A; then the melting temperature is 32°C , 500g of n-nonadecane with a melting heat of 220J / g was melted and slowly added to system A. After mixing evenly, it was emulsified under high-speed shear at a speed of 8000rpm. After emulsifying for 50min, a uniform and stable emulsion was obtained. The average particle size of the milk droplets was 1 μm; then spin under the conventional process to obtain the acrylic fiber with a single filament diameter of 40 μm, and put the 1kg dry acrylic fiber dried to constant weight into the hydroxyl modified polysiloxane organosilicon finishing agent emulsion with a concentration of 50wt% In the process, use acetic acid to adjust the pH value to 5, soak it at 55°C for 1 hour, take it out, wash it and roll it dry, then dry it at 100°C to constant weight and bake it a...

[0024] First, 150 g of polyvinyl alcohol with a degree of polymerization of 1755 was dissolved in 1 kg of deionized water, and then 5 g of sodium dodecylbenzenesulfonate was added to form a homogeneous aqueous phase A. After melting 75g of 1-tetradecyl alcohol with a melting temperature of 38.0°C and a melting enthalpy of 205 J / g, it was added to the water phase A, and a uniform and stable emulsion was obtained after shear emulsification at a speed of 10,000 rpm for 30 minutes. The diameter is 0.1 μm, and then spinning under the conventional process, after post-treatment such as drafting and acetalization, a heat storage and temperature regulating vinylon wig with a single filament diameter of 20 μm can be obtained.
