Description
Technical field
The present invention relates to the process field of scrap fabric, and in particular to regeneration PA plastics prepared by a kind of utilization scrap fabric
Particle and preparation method thereof.
Background technology
It is well known that with the development of science and technology, the market share of the medicated clothing cloth that is made using synthetic fibers is constantly expanded
Greatly, economic productivity is growing.But simultaneously as the update of medicated clothing, has waste and old medicated clothing in a large number to become solid waste every year
Thing, this solid waste is difficult to degradable in its natural state, brings huge environmental pressure.At present for waste and old clothing
Waste and old medicated clothing is mainly fabricated to mop after process by the recycling of thing, is reused or is sold, but this mode is produced
The low, audient of energy is narrow, economic benefit is low, and the waste and old medicated clothing of consumption is limited.Accordingly, it would be desirable to expand utilizing on the way for such waste and old medicated clothing
Footpath, strengthens production capacity, increases economic benefit, reduces environmental pressure.
Plastic pellet is of many uses, cheap, simple processing, is received by the market, and market share constantly expands, with
Plastics yield constantly to increase, plastic refuse causes very big environmental pollution, therefore, the regeneration of plastics is just seemed
Particularly important.At present, it is mainly various plastic products to the raw material that the regeneration of plastics is adopted, for example agricultural film, bag weaved, square
Just bag, carafe, plastic tub bucket, old sandals etc., are obtained plastic pellet.And the synthetic fibers medicated clothing garbage of substantial amounts is to the greatest extent
It is also the high polymer composition such as PA, PC, PET to manage its composition, and its utilization rate is still relatively low.
Chinese patent CN201510257877.3 discloses a kind of recovery method of clothing waste cloth, specially：Select
Scrap fabric, is cut into strip, using medicining liquid dipping, is rinsed well with clear water；Useless cloth is soaked using cleanout fluid, is then used
Clean water is clean；Useless cloth is processed at 105 DEG C -110 DEG C；Cloth is carried out immersion treatment using herb liquid；Cloth is dried in the air
Dry, make mop.But the method production capacity of the patent utilization waste cloth is low, audient is narrow, economic benefit is low, the waste and old clothing of consumption
Thing is limited.
Chinese patent CN201510249081.3 discloses a kind of production technology of recycled plastic granules, by waste or used plastics point
Crushed after level, then carried out except ferrum process；Then subregion washing is carried out to pretreated waste or used plastics, is then dried；Most
Extrusion, wire drawing, cooling, pelletizing afterwards, makes recycled plastic granules finished product.But the standby regenerated plastics particle of the patent system is still traditional
Ground adopts waste or used plastics to increase the raw material sources of regenerated plastics particle for raw material, not, and market unification is obvious.
Therefore, regenerated plastics particle is prepared using the fibrous material in medicated clothing garbage obtained in synthetic fibers, not only may be used
To increase the Land use systems of medicated clothing garbage obtained in synthetic fibers, pollution and burden to environment is reduced, moreover it is possible to improve such
The regeneration economic worth of garbage, tool are of great significance.
