Description
Technical field:
The present invention relates to brush silk preparation method, be specifically related to two one-time formed preparation methods of pointed bristles.
Background technology:
The head of tooth brush monofilament is generally tack, and this toothbrush is in the process of brushing teeth, because the brush silk is thinner, ratio of rigidity is relatively poor, is difficult for filling in tartar or dirt removal in teeth space, is difficult to the effective cleaning oral cavity.Along with scientific and technological progress and social development, people had released pointed bristles in recent years, when being made into toothbrush with this brush silk, can the tartar in the teeth space, dirt removal is clean, thus obtained consumer's welcome.
At present, this pointed bristles is through melt spinning with nylon or copolymer nylon or polyester or copolyester, and after thermal finalization, wrap pre-packing more outside and twine film formation tow, tow is cut into spinning cake, again water and inorganic agent are put in a termination of spinning cake: any treatment fluid of converting of sulfuric acid, hydrochloric acid, phosphoric acid, potassium hydroxide, NaOH, lithium hydroxide or aldehydes matter, wherein the addition of inorganic agent is 20～80% (percentage by weights), the treatment temperature of treatment fluid is 50～200 ℃, and the processing time is 1-60 minutes.But there is following defective in present this brush silk preparation method:
The one, production efficiency is lower.Be above-mentioned treatment fluid to be put into the pointed bristles forming tank (treatment fluid is generally the spinning cake length of need handling 1/3～2/5 in the preparation process, be generally about 10mm), spinning cake one termination is immersed in the treatment fluid, treatment fluid need remain on design temperature simultaneously, the process regular hour then forms pointed bristles, take out the spinning cake winding film of unpacking then, will brush that silk cleans, oven dry, put moulding in order again and be packaged as finished product.Obtain the brush silk that two ends is tip as need, then after the arrangement moulding, repeat said process.As seen this processing method once can only be finished the processing of a termination, and cleaning, finishing and packing workload are big, and production efficiency is low.
The 2nd, energy consumption is big in the process.In the process of pointed bristles, forming tank is (not the adding lid) of opening wide all the time, and the condition of molding of pointed bristles needs uniform temperature, because forming tank is opened wide, and forming tank is dispelled the heat, disengagement area is very big, need often add entry or low-concentration alkali liquor accent in addition and convert treatment fluid concentration, therefore, energy resource consumption is big.
The 3rd, the big and contaminated environment of inorganic agent consumption.Used inorganic agent is solution such as alkali or acid in the pointed bristles production, because the treatment fluid degree of depth very shallow (being generally 10 millimeter) in the forming tank, the thick corrosion thing that is produced in the production process is mixed in treatment fluid, be difficult to separate, therefore, after handling several or several batches, treatment fluid will be outwelled and to renew, otherwise will influence the quality of pointed bristles, not only waste raw and auxiliary material and contaminated environment.
The 4th, operationlocation's environment is relatively poor.Because treatment temperature (generally can selected the treatment temperature more than 100 degree for use) between 50-200 degree, and a large amount of water vapours fills the air in the space, especially summer, operating environment was very abominable in the production process.
Summary of the invention:
The objective of the invention is to overcome defective of the prior art, a kind of preparation method of pointed bristles is provided, its production efficiency height, the energy in the production process, inorganic agent consumes low, good operational environment.
The present invention is achieved through the following technical solutions:
A kind of couple of one-time formed preparation method of pointed bristles may further comprise the steps:
(1) forms tow with the polyester capillaries outside that it is good that film is enclosed within spinning, tow is cut into the spinning cake of Len req with cutter;
(2) polytetrafluoroethylsheet sheet is cut into the dressing of rectangle sheet; Dressing length * loose height * girth of slightly being longer than spinning cake respectively;
(3) dressing that obtains with step (2) is wrapped in the spinning cake periphery that step (1) obtains, and with the band bundle in the two ends of spinning cake dressing periphery;
(4) in pointed bristles moulding still, add inorganic agent: NaOH, potassium hydroxide or lithium hydroxide and water, wherein the addition of inorganic agent is 28～42%, unit is a percetage by weight, makes the pointed bristles treatment fluid, treatment fluid is heated to 115～128 ℃ again;
(5) spinning cake that step (3) is obtained is put into the treatment fluid that step (4) obtains, and it is immersed in the treatment fluid fully, and covers the lid of moulding still, handles 25～35 minutes 115～128 ℃ of insulations again;
(6) lid of opening steps (5) moulding still, from treatment fluid, take out spinning cake, remove spinning cake outer coatings (keeping the film that is overlapped), also water flushing under external force (rub with the hands, squeeze) effect, remove raffinate and a small amount of corrosion thing, put into fixed mount again and dewater, remove the moisture on pointed bristles surface, pointed bristles is dried or uses oven for drying with dewaterer;
(7) two pointed bristles that step (6) is obtained are packaged into two pointed bristles finished products with packaging material, or with cutter the pointed bristles that step (6) obtains are cut into two-section, are packaged into single pointed bristles finished product with packaging material again.
The present invention optimizes polyester as the tow raw material from prior art, the property of utilizing polyester to have, hydrolysis (peeling) promptly takes place in alkaline solution, and be the characteristic of in layer degrading and make two pointed bristles, theory and practice proves that all the other tow raw materials do not have this characteristic, all can not produce pointed bristles in the solution of described alkali, acid, phenol; Select NaOH for use, potassium hydroxide or lithium hydroxide are as inorganic agent, and more preferably NaOH is inorganic agent; The concentration of inorganic agent is 28～42% in the treatment fluid, more preferably 33～36%, more preferably 35%; Treatment temperature is 115～128 ℃, more preferably 118～122 ℃, and more preferably 121 ℃; The insulation processing time is 25～35 minutes, more preferably 28～32 minutes, and more preferably 28 minutes.Such treatment process can be produced the qualified products that two ends are tip by adjusting process condition (concentration of inorganic agent, treatment temperature and processing time) fixed length according to the required cone length of brush silk.
The present invention further improves brush silk hydrolysis and seepage velocity under the same process condition, adds LE-600 or the alkaline-resisting promoter 0.1-10g/L of FN in the treatment fluid of moulding still, adds JFC or OEP-70 alkali-resistant penetrant 0.1-10g/L.Alkaline-resisting promoter, bleeding agent kind are a lot, all produce effect after the adding.
The present invention forms tow at the outside of silk cover film, but not forms tow with twining film, and the same function that both are had except the shape that keeps spinning cake, the cover film is in order to improve the operating efficiency of the cleaning of road, back, packaging process.
