Description
Technical field
The present invention relates to a kind of underwear and cup bra production technical field, more particularly, to polyurethane material manufacture permeable, ventilative not
Deformation underwear and cup bra manufacturing technology.
Background technology
With the development in epoch, women is progressively liberated, and love women's health is one of themes of the times.From France's invention
Since corset, women underwear culture constantly develops, and cup becomes the medicated clothing design focal point of female body health.Selection from cup
The product style 1,100 drawing to manufacturing process, but every money product more or less all has different journeys to female body health
The hidden danger of degree.
Sandwich fabric because its breathability, flexible adjustment, wear-resisting not balling-up, antimildew and antibacterial, washable easily dry the advantages of, obtain
Some crowds like, but sandwich fabric is as underwear and imperfect.The underwear that sandwich fabric makes can not play very
Good antihunt action, and unsightly；Product type does not have to be segmented, and the women of different building shape dress requires inconsistent, for body
For the unaccommodated women of type, can endanger healthy.
The intensity of sponge typically can play shockproof and protection effect, but because selection and manufacturing process are uncomfortable, exists
Ventilative not good, it is unfavorable for perspiring；Water penetration is bad, leads to cleaning trouble, easily hides dirty long bacterium.
Documents 1：Chinese invention patent application notification number is " CN104817681A ", and date of publication is August 5 in 2015
Day, entitled《There is formula and the foaming manufacturing method of water penetration polyurethane underwear and cup bra sponge》Disclose as follows in application documents
Technical characteristic：Polyether polyol 20%-69.78%, polymer polyatomic alcohol 5-30%, isocyanates 20%-40%, water 1%-
5%, silicone oil 0.1%-2%, ammonium catalyst 0.01%-0.9%, reactive ammonium catalyst 0.01%-0.9%, tin catalyst
0.1%-2%, dichloromethane 2%-10%, antioxidant 1%-8%, organosilicon oxygen affinity water preparation 1%-7%, in this technical scheme
Disclosed manufacturing process is as follows：
1st, first various raw materials are stirred in each storage tank and control temperature at 15-35 DEG C；
2nd, each raw material is sufficiently mixed by proportioning；
3rd, compound issues in an atmospheric pressure environment 20 meters of 1.6 meters wide 2 meters of high bellows through cloth about gondola water faucet
Bubble, becomes sponge；
4th, sponge is pressed the cutting of cup specification, then the cup being hot pressed into different size through thermocompression forming equipment.
Although choosing above-mentioned raw materials in documents 1 to manufacture polyurethane sponge cup, there is certain water penetration, effectively reduce
Mycete grows to be hidden with dirt, but using poisonous and harmful substances such as dichloromethane in its manufacturing process, even if micro use, right
Wear next to the skin medicated clothing in for a long time, direct skin contact can absorb to it, still can endanger healthy；In addition, foaming, molding procedure
Trouble, needs to be foamed first with bellows, carries out cutting again, hot-forming, needs equipment investment more, affects the production cycle, with
When the technological parameter such as the temperature that foams foaming effect can not be played to optimal, thus making properties of product have limitation.
