Abstract
The invention discloses a producing method of degradable nonwoven fabric. Degradable fiber is selected as raw materials. The method includes: a step of mixing the raw materials of the nonwoven fabric, heating, and stirring uniformly until the raw materials are in a uniform melt fluid state; a step of feeding raw material pieces into a twin screw extruder, heating to melt the raw material pieces, stirring uniformly the melt fluid, and extruding the melt fluid out of the extruder; a step of filtering the extruded melt fluid by a filter to remove impurities, further uniformly mixing through a static mixer and feeding the melt fluid into a spinning system; a step of allowing the melt fluid to cure to form filaments through the spinning system, paving the filaments on a conveying net uniformly to form a web, winding in a winding and rolling machine after web forming and hot rolling, slitting through a slitter machine and drying to obtain nonwoven fabric; and a step of coating thermoplastic polyurethane (TPU) film having a thickness of 0.012 mm with glue, preheating the film, subjecting the film and the obtained nonwoven fabric to thermocompression bonding, and cooling to obtain a finished product. The finished product is tough, durable, environmental friendly and degradable.
Description
Technical field
The invention belongs to field of nonwoven fabric technology, be specifically related to a kind of production method of degradable nonwoven fabrics.
Background technology
Nonwoven is to be made up of orientation or random fiber, is environment-friendly materials of new generation, has protection against the tide, ventilative, pliable and tough, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant, rich color, the feature such as use again cheap, capable of circulation.Non-woven fabric bag is compared with polybag, and non-woven fabric shopping bag is reusable more than 10 times, after discarding, the dustiness of environment is also only had to 10% of polybag.In addition, nonwoven also has the sensation of cotton, compares with cotton goods, and nonwoven more easily shapes.
Summary of the invention
The above-mentioned technical problem existing in order to overcome prior art field, the object of the invention is to, a kind of production method of degradable nonwoven fabrics is provided, simple to operate, throughput rate is fast, output is high, cost is low, purposes is wide, gained nonwoven is tough, durable, environmental protection, degradable.
The production method of degradable nonwoven fabrics provided by the invention, comprises the following steps:
(1) raw material is prepared, and selecting biodegradable fiber is raw material;
(2) former material melting, by selected nonwoven raw material Hybrid Heating, and stirs, until raw material become uniform melt flow stream state;
(3) material piece enters twin (double) screw extruder, and then melted by heat stirs melt flow stream to extrude from extruder;
(4) melt flow stream being extruded is removed impurity through filter, and further mixes through static mixer, then enters spinning system;
(5) melt flow stream is consolidated into silk through spinning system, and then uniform spreading is on transmission net, and piddler becomes net, enters rolling machine and batches, then cut by cutting machine after becoming net hot rolling, after drying, obtains nonwoven;
(6) material pressing: get the thermoplastic polyurethane TPU film gluing that 0.012mm is thick, preheating, carries out hot pressing with gained nonwoven afterwards, cooling getting product afterwards.
Described biodegradable fiber is natural fiber preferred cotton fiber, with mixing of chemical fibre viscose rayon, polylactic acid PLA fiber.
The production method of degradable nonwoven fabrics provided by the invention, its beneficial effect is, and technique is simple, and throughput rate is fast, output is high, cost is low, purposes is wide; Gained nonwoven does not produce Soft flocks, and tough, durable, gas permeability is good, easily keeps that cloth cover is dry and comfortable, easily washing, and environmental protection, degradable.
Detailed description of the invention
Below in conjunction with an embodiment, the production method of degradable nonwoven fabrics provided by the invention is described in detail.
Embodiment
The production method of the degradable nonwoven fabrics of the present embodiment, comprises the following steps:
(1) raw material is prepared, and selecting biodegradable fiber is raw material;
(2) former material melting, by selected nonwoven raw material Hybrid Heating, and stirs, until raw material become uniform melt flow stream state;
(3) material piece enters twin (double) screw extruder, and then melted by heat stirs melt flow stream to extrude from extruder;
(4) melt flow stream being extruded is removed impurity through filter, and further mixes through static mixer, then enters spinning system;
(5) melt flow stream is consolidated into silk through spinning system, and then uniform spreading is on transmission net, and piddler becomes net, enters rolling machine and batches, then cut by cutting machine after becoming net hot rolling, after drying, obtains nonwoven;
(6) material pressing: get the thermoplastic polyurethane TPU film gluing that 0.012mm is thick, preheating, carries out hot pressing with gained nonwoven afterwards, cooling getting product afterwards.
Described biodegradable fiber is natural fiber preferred cotton fiber, with mixing of chemical fibre viscose rayon, polylactic acid PLA fiber.
