Abstract
The invention relates to the technical field of waterproof cloth production and processing, and particularly relates to a plastic waterproof cloth production process. The process comprises the steps of material preparation, wire drawing, weaving, film coating, and reprocessing. According to the invention, through a unique film mulching process, a knitted waterproof cloth semi-finished product is mulched with a film again, so that the waterproof effect of waterproof cloth is enhanced, and the consistence of the whole waterproof cloth is also increased, thereby prolonging the service life of the waterproof cloth. According to the invention, a large amount of regenerated low-density polyethylene is used, so that the cost can be reduced, and the quality can be guaranteed; and due to waste utilization, an effect of environmental friendliness is facilitated. In the whole production process, no 'three wastes' pollution is caused, and no emission is performed, therefore, the process has significant economic and social benefits. In addition, products of the invention have a high waterproof function, and are short in process flow, simple and convenient to operate, capable of being performed on common printing and dyeing equipment, and low in economic cost.
Description
Technical field
The present invention relates to waterproof cloth production and processing technical field, particularly a kind of rain-proof plastic cloth production technology.
Background technology
Waterproof cloth procedure of processing under prior art, generally comprises wire drawing, weaves cotton cloth, the technique such as reprocessing, but current waterproof cloth generally has following deficiency:
1, complex process, whole production process operation is many, goes out cloth rate low.
2, the waterproof effect of waterproof cloth is determined by weaving quality, once braiding process is made mistakes, then can bring the decline of whole waterproof cloth waterproof effect.
3, waterproof cloth quality is not good, and service life is short.
Summary of the invention
In order to solve the problem of prior art, the invention provides a kind of rain-proof plastic cloth production technology, not only technique is simple for it, and the waterproof cloth waterproof effect produced is good, and service life is of a specified duration.
The technical solution adopted in the present invention is as follows:
A kind of rain-proof plastic cloth production technology, comprises the following steps:
A, raw material to be prepared burden according to following mass percent proportioning: regeneration low density polyethylene (LDPE) 80%; Ultra-violet absorber 5%; Additive 10%; Color masterbatch 5%; Be transported to wire drawing machine after aforementioned base materials being carried out stirring half an hour, use screw rod heating system to heat, after raw material is melted, from die head extrusion film;
B, conveying after water tank cooling, then through knife rest pull-out silk;
C, drawing-off: shape after drawing-off plate stretching, then rolling, be rolled onto diameter 25 centimeters with regard to last volume, put in storage after last volume after rolling;
D, to weave cotton cloth: through the silk volume of warehouse-in after hanging wire, cross eyelet strip through steel button, deckle board, after become semi-finished product cloth through longitude and latitude interlacing, eventually pass water squeezing system and extract rolling warehouse-in after moisture;
E, film: extract according to operation instruction the semi-finished product cloth woven and enter wringing machine, dossal, after the moisture of cloth cover is extracted by water squeezing system, enter drying system, and it is female to add colouring, then after heating system, enter water squeezing system, rolling after the cloth of generation band film.
In step C, it is 7 times to the stretch ratio of cloth silk.
The beneficial effect that technical scheme provided by the invention is brought is:
The present invention is by unique coating technique, by woven waterproof cloth semi-finished product overlay film again, thus while its waterproof effect of enhancing, too increase the robustness of whole waterproof cloth, thus extend its service life, present invention uses and regenerate low density polyethylene (LDPE) in a large number, both can reduce costs, can ensure the quality of products again, and slug detect, be conducive to environmental protection.Whole production process does not have three-waste pollution, without discharge, has significant economic and social benefit.In addition, product of the present invention has more high water-proof function, and technological process is shorter, easy and simple to handle, and can carry out on general dyeing apparatus, financial cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the production technological process of a kind of rain-proof plastic cloth of the present invention.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment one
As shown in Figure 1, a kind of rain-proof plastic cloth production technology of the present embodiment, comprises the following steps:
A, raw material to be prepared burden according to following mass percent proportioning: regeneration low density polyethylene (LDPE) 80%; Ultra-violet absorber 5%; Additive 10%; Color masterbatch 5%; Be transported to wire drawing machine after aforementioned base materials being carried out stirring half an hour, use screw rod heating system to heat, after raw material is melted, from die head extrusion film;
B, conveying after water tank cooling, then through knife rest pull-out silk;
C, drawing-off: shape after drawing-off plate stretching, the stretch ratio of cloth silk is 7 times, then rolling, is rolled onto diameter 25 centimeters with regard to last volume, puts in storage after last volume after rolling;
D, to weave cotton cloth: through the silk volume of warehouse-in after hanging wire, cross eyelet strip through steel button, deckle board, after become semi-finished product cloth through longitude and latitude interlacing, eventually pass water squeezing system and extract rolling warehouse-in after moisture;
E, film: extract according to operation instruction the semi-finished product cloth woven and enter wringing machine, dossal, after the moisture of cloth cover is extracted by water squeezing system, enter drying system, and it is female to add colouring, then after heating system, enter water squeezing system, rolling after the cloth of generation band film.
F, job shop: the cloth of outbound drops into job shop and produces, and dossal, carries out severing by cutting machine according to the specification size of order.Carry out again beating button, have special dotter, carry out beating button according to customer requirement.Last laying up, pack, sealing, pressure bag, packing.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
