Abstract
The invention provides a non-stick hot melt adhesive, prepared from 10-80 parts by weight of thermoplastic elastomer and 1-30 parts by weight of flexibilizer as raw materials, wherein the thermoplastic elastomer is of the polyamide group. Found through repeated tests by research personnel of the company, injection molding can be directly carried out on the non-stick hot melt adhesive in a mold, and compared with silica gel, the processing technique is simpler and dispenses with an injection process by manually producing TPU bags, wherein the injection process mainly depends on manual work currently, and after injection is completed, moulds are fixed manually and put into a high temperature oven for shaping. Therefore, the non-stick hot melt adhesive processed into bra cups can save a big amount of manual work and reduce the material cost by non-use of a TPU film.
Description
Technical field
The invention belongs to dress material technical field, do not glue PUR and preparation technology thereof particularly to one.
Background technology
The existing silicone bra commanded a ready sale in the market, need TPU film and instillation process, silica gel is irrigated in TPU film, it is fabricated to the semicircle brassiere of a kind of closely human breast musculature, wear this brassiere, at tying up band and needn't worry to expose during evening dress in summer, the same with contact lenses.Although concealed bra and human contact do not have bad reaction, but can be limited by gas permeability；It can not be dressed by 24 hours, because the ground of silica gel material itself is the most closely, certain thickness is had plus many silica gel, put on airtight, this is the biggest to the injury of chest, too closely will not have gap with contacting of skin, sweat plays and does not goes out, and causes local temperature higher.If at high temperature, the chest long period is soaked by sweat and is just easy to have redness, itch etc., generates the skin diseases such as eczema goods prickly heat.Women's health is caused potential hazard by this closed feature that cannot breathe.
To this end, a kind of material prescription of exploitation can simplify processing technology, reducing production cost, the cup thickness of making reduces and permeability is excellent, and such bra cup will be by manufacturer and the very big welcome in market.
Summary of the invention
For a difficult problem for prior art, it is an object of the invention to provide a kind of non cohesive gel.
For realizing object above, the technical scheme is that
One does not glue PUR, and raw material includes: thermoplastic elastomer (TPE) and toughener, and in raw material, the parts by weight of component are respectively as follows: thermoplastic elastomer (TPE) 10-80；Toughener 1-30, described thermoplastic elastomer (TPE) is polyamide-based.
Described toughener is polyisobutene.
Raw material also includes the naphthenic oil of 30-90 weight portion or any one or two kinds of mixtures of White Mineral Oil.
The parts by weight of described raw material are respectively as follows: naphthenic oil 30-80；Thermoplastic elastomer (TPE) 30-80；Toughener 1-20.
A kind of bra cup, bra cup is prepared by the described PUR that do not glues.
Adhesive-layer it is provided with in bra cup.
Connected mode between described cup is any one that stay cord connection, snapping and VELCRO connect.
The preparation technology of a kind of bra cup, has a including step, is mixed in still by raw material, b, is heated to 160-250 DEG C of melting sources；In c, injection mould, cooling shaping, prepare the bra cup of required form.
Described mould is provided with for the Kong Zhu for brassiere drilling；Brassiere is provided with air-vent or the stay cord hole connected.
The attachment means of straight forming it is provided with in described mould.Attachment means includes bales catch, VELCRO.
Beneficial effect:
I takes charge of research staff through repetition test, find that this kind of non cohesive gel can directly injection mo(u)lding, compare with silica gel, processing technology is simple, it is not necessary to above manual manufacture TPU bag instillation process, and instillation process is the most manually, shape by putting in high temperature saggar after artificial fixing with mould again after having irrigated, so the non cohesive gel of the present invention is processed into bra cup and can save and substantial amounts of manually and need not use TPU film, reduce material cost.
Because silica gel has instillation process, thus can not punching, and silica gel is poisonous, it is impossible to contact skin, and skin-proximal is the TPU film on silica gel top layer.And the non cohesive gel of the present invention can be punched out at any time, improve the gas permeability of brassiere.
Comparing with traditional silica gel, brassiere prepared by the non cohesive gel of the present invention is with the obvious advantage, compares with the cup of cloth, and between formed in mould cup, attachment means can straight forming, it is not necessary to secondary operations, saves punching or the time of the technique such as BAR-TACK, sewing.
