A kind of production process of cold silicone liner
Technical field
The present invention relates to a kind of production technology of adhesive lining, specifically, relate to a kind of production process of cold silicone liner.
Background technology
The lining cloth of conventional coatings technology (hot melt transfer, dusting, powder point), base cloth needs the high temperature heating in the production process, and rubber powder is transferred on the base cloth under molten condition, cools off rolling then and forms.Because base cloth needs the high temperature heating, the style of lining itself can't embody, thereby has influenced the moulding of clothes and taken performance.
Summary of the invention
The object of the present invention is to provide a kind of production process of cold silicone liner, can effectively solve existing lining cloth coating technology needs the high temperature heating and fabric style can't be embodied, and influences the problem of apparel modeling and performance.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of production process of cold silicone liner comprises the steps:
A. the base cloth of producing is carried out impregnation process, add the nonionic mes liquid of the amino-modified silicone oxygen alkane of fabric weight 1%-3%, treatment temperature is 40-50 ℃, processing time is 15-20 minute, adopt then and pad technology, pick-up rate is about 50%, again 120-150 ℃ of oven dry;
B. the check, cropping;
C. the cold spot coating is advanced cloth, some glue: directly be applied on the base cloth equably by the cylinder scraper polyamide hot, the cylinder order is counted 140-180 order, aperture 0.12mm, thickness 0.02mm, the speed of a motor vehicle: 30m/min, 20-30 ℃ of workshop condition temperature, humidity: 60%-70%;
D. again through batching, checking, obtain finished product.
Preferably, the nonionic mes liquid addition of the amino-modified silicone oxygen alkane of described A step is 2% of a fabric weight, and treatment temperature is 50 ℃, and the processing time is 20 minutes, 140 ℃ of bake out temperatures; The cylinder order number of described C step is 180 orders; Can reach the technological parameter of better effects.
Compared with prior art, advantage of the present invention is: adopt the super flexible nonwoven base cloth handled through silicone oil and polyamide hot to form through cold spot is transfer coated, need not heating, original material of base cloth and style have been guaranteed to the full extent, product glue point is clear, do not fall glue, adhesive fastness and quality stability height.It is convenient to change product operation simultaneously, changes kind, draping and only needs a few minutes, will treat that unlike powder point method the engraved roll cooling reheated after two hours.
Description of drawings
Fig. 1 is the process route chart of a kind of production process of cold silicone liner of the present invention.
The specific embodiment
Consult the embodiment of Fig. 1 for a kind of production process of cold silicone liner of the present invention, a kind of production process of cold silicone liner, comprise the steps: that A. carries out impregnation process to the base cloth of producing, the nonionic mes liquid that adds the amino-modified silicone oxygen alkane of fabric weight 2%, treatment temperature is 50 ℃, and the processing time is 20 minutes, adopts then and pads technology, pick-up rate is about 50%, again 140 ℃ of oven dry; B. the check, cropping; C. the cold spot coating is advanced cloth, some glue: polyamide hot directly is applied on the base cloth equably several 180 orders of cylinder order, aperture 0.12mm, thickness 0.02mm, the speed of a motor vehicle: 30m/min, 20-30 ℃ of workshop condition temperature, humidity: 60%-70% by the cylinder scraper; D. again through batching, checking, obtain finished product.
Directly equably spread upon base cloth on by the cylinder scraper polyamide hot, owing to need not to add any additive that influences the rubber powder fastness, so under the situation of equal spread, compare with transmission slurry point, it is many that fastness is better than sizing point padding cloth, saved and sized mixing, need not evaporate in the slurry 70% moisture content, energy-conservation about 50%.It is convenient to change product operation simultaneously, changes kind, draping and only needs 4 minutes, will treat that unlike powder point method the engraved roll cooling reheated after two hours.Because of base cloth does not need high temperature heating, spin, non-woven base cloth all can keep original material of base cloth and style.Compare with slurry point method, do not need auxiliary agent, adhesive fastness and quality stability height.Following table is for adopting the NT5255 basic mechanical design feature index of this explained hereafter:
