Description

L3〇5540 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a kind of seamless article (seam solution, cup, military top and bra, and other items used in clothing). The method of the present invention It is especially suitable for the cups of bras made of polyurethane foam made by the jointing of the aliphatic isocyanate compound.

In the preparation of bras and other garments with shaped breast cups, it is often necessary to use them to maintain the original shape, but it can be heard. She, she lost and bombed _ must be maintained under the artificial and machine silk. In addition, bra cups must have sufficient porosity and breathability to improve wearer comfort. The traditional breast material (4) is made of filler fiber (f_) (4), and is made into cups of different thicknesses. The disadvantage of the conventional technique is that the thickness is thinner at the top of the cover, resulting in no artifacts after manual and machine washing (4) to overcome this fine problem, and the stitching at the top of the cover is solved. However, the way of suture can not meet the recent demand for the lack of lying cups. The improved bra cup method was published in U.S. Patent No. 4, No. 25,597, and (10) year (monthly) is awarded to "hiS_mot." The hair is made of a type of shirt (8). The special material towel, the new bottle _ is placed in the surface mold (five) (10) (4) heated to higher than the Wei Wen Wei Wenhong, the county cup. This fiscal "forms the distribution of thermoplastics in the fiber tree." And using this method to make a uniform softness and elasticity of the straw cup, the material. Another - meaning is that the fine must be controlled to control the content of Hong. Too much resin will make a stiff cup into the mouth. The cup is lacking (four) raw. On the other hand, if the resin content is too small, it is possible that 5 1305540 is deformed by washing and cannot maintain its shape. Another method of preparing a bra cup is to use a thermosetting urethane blister/encapsulated body such as U.S. Patent No. 4,25, 137 (issued to Walter Riedler on February 1, 1981). Show. The method. The preparation steps include: placing a - piece of polyaminating 'base foaming foam' on a bulk poly-amino citrate block foam, placing it in a two-phase mold, that is, heating - a male mold and - Among the mother molds. According to the patents and patents, the cans are heated to 35G.45G °F. The polyurethane foam material was subjected to a pressure of about 6 mash per square inch (to the surface of the mold), and the polyurethane foam was preheated, and the coffee was about 4 〇 0 F. At the same time, it is pressurized and heated for about 60 seconds, but the actual reaction period varies depending on the thickness of the polyurethane bismuth silicate foam sheet. Due to the low thermal conductivity of the polyurethane foam material, a relatively large thickness of the foam sheet often requires a long process time to produce sufficient decoration at the center of the polyurethane foam material. On the treatment of the lining, the chemical chain of Jia Linlin was broken (dissociatiGn). The physical impurities of the resulting product are reduced, and the use of the lying polyurethane foam accelerates yellowing. The obvious disadvantage of using an aromatic polyurethane foam is its discoloration characteristics. As is known, Fang Wei gathers the chaos? _The foam is exposed to light, especially under ultraviolet light. In the European Patent λ σ case G, 473, 1 〇 7 of Kiyotake, a method for solving the above problems is disclosed. The step of the Ming Dynasty includes adding an aliphatic iso-acid acid (for m.6 hydrazine base equivalent) and water (for 重量4_5 percentage of the weight of the polyol) to a polyol (p〇ly〇1). The reaction is carried out in the presence of the medium. The method of hai can produce; the fat of arsenic is a yellow foam. However, the aliphatic polyurethane foam contains a closed cell (cdl) in most of its structure due to the low reaction rate of the aliphatic isocyanate group, resulting in a small The cell cannot be ruptured. The closed cell structure is difficult to form on the polyurethane 6 1305540 hot press forming, so that the foam bra gasket prepared by hot press forming is a urethane containing foam. This results in slower heat dissipation efficiency and higher thermoforming temperatures and longer processing times. Residual cell membranes can only provide limited gas permeability. Another problem with thermoformed polyurethane tarpaulin gaskets It is the gas-reducing property caused by the low porosity obtained after thermoforming. Chen provides a manufacturing air hole with the upper surface and the lower surface in the 6th, 3rd, and 1st of the year 1G. The method of connecting the polyurethane 塾 塾 ,, (4) the improved permeable button, but the softness of the fresh cup made of these air holes and

Appearance, bringing negative Qing. Silk, this fresh cup is very limited in market acceptance. SUMMARY OF THE INVENTION <Objectives of the Invention> The above-described difficulties of the prior art can be solved by the present invention. The present invention can be used to make molded bra cups' having sufficient porosity and gas permeability. Thereby, an aliphatic polyurethane foam bra cup having ultraviolet resistance and excellent coloring resistance was obtained. The present invention also provides an economical production of a chest-turn (four) method for producing a bra cup having high gas permeability and maintaining softness. The object 75 of the present invention is to provide a method of using a polyamino-based foamed material, which is suitable for use in seamless joints, cups, (four) and the like, and to solve other clothes. Another object of the present invention is to provide a novel method for increasing the heat dissipation of the foam during the hot forming process, reducing the molding temperature and shortening the process time. The method of the present invention prevents degradation of the polymer in extremely high temperature environments and protects the worker from exposure to toxic hydrogen cyanide fumes produced by the thermal decomposition. Another object of the present invention is to provide a method of molding a bra cup to achieve a shorter process time. 7 1305540 Bra cover cup mold production _ seam will be (4) significantly improved. Since the process time is short, the '6 black bra cup contains a heat sensitive cloth made of an isocyanate and a polyurethane foaming material which is also a process of molding a bra cup. There is a real need in the industry for bra cups to maintain their original color during use. All of the polyamino oxime foams prepared by the aromatic isocyanine will gradually light up due to illumination and gradually turn yellow and dark brown. Conventional techniques generally solve this problem by adding an ultraviolet stabilizer to the polyaminodecanoic acid (iv) bubble composition. But the material line can stabilize the speed of yellowing and the validity period

In only a few weeks, the polyurethane will eventually become a significant yellow smear in the polyurethane foam. For the bra cover _ words, the use of cyanide _ made by the collection of the purpose of the hair is the best material. Since the amino acid (5) obtained from the aliphatic family record, the chemical bond is unstable compared to the family of acetoacetate, and its chemical bond may be broken even at low temperatures. Therefore, the conventional thermoforming process cannot be used to mold a polyamino cap-foamed body made of an aliphatic heterogeneous. The present invention has been made in view of the prior art to produce a hetero-method foam which can be molded (four) by a cyanide. <Simplified Invention of the Invention> The present invention provides a novel method for producing a polyurethane foam, and the obtained foam material is suitable as a non-contact gasket, a cup, a cover, and a reading thereof. In fresh and other clothing. The method of the present invention is particularly suitable for the preparation of a fresh polyurethane-based foaming material produced by the reaction of a polyester with a polyol. The fat of the amino acid ^_ The foaming system is treated by reticulating k fine 丨MO, and the material is _ (eeu_b surface), and then cut into pieces to make the thickness of the cup thicker. thick. The difficult-to-join fresh I cup has a thicker wall at the tip end or the protruding portion, and the thickness is thicker than the side portion. After (4), the polyurethane 8 1305540 acid ester foam sheet is placed between a mother mold and a mold assembly composed of a male mold, and pressurized. The mold assembly is closed and pressurized with hydraulic pressure. The aliphatic polyurethane foaming material thus forms the same shape as the inner cavity of the mold. The molded aliphatic polyurethane foam can be used as a seamless bra pad, cup, hood top and the like for bras and other clothing. The molded aliphatic polyurethane bra shims have superior yellowing characteristics compared to conventional aromatic bra shims, and have improved body temperature divergence due to their improved gas permeability and porosity. According to a preferred embodiment of the present invention, the aliphatic polyurethane foaming system directly reacts with aliphatic isocyanide in the presence of water and a catalyst. After aging for several days, the outer skin portion of the polyurethane foam group was removed. The polyurethane foam group is additionally subjected to reticulation (ret-) to remove the small cells of the foaming lining, and a net-like structure having only a skeleton is obtained. After reticulation, the polyaminophthalic acid bubble is cut into a sheet having a thickness approximately twice that of the thicker portion of the bra cup to be made. (4) The obtained polyaminoethylene foam sheet is placed in a mold assembly composed of a mother-and-male model to be heated. The mold assembly is closed and pressurized with hydraulic pressure. The pressure of the (4) poly-I-based 曱8_foam (4) is about 6 (four) / square 忖 (on the surface of the mold) „ 氨基 氨基 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

The field of the sputum can be used to make bras and straight clothes. , "/ΜΙSeamless bra cups have a thickness thicker than their peripheral portions at their protruding or pointed ends. [Embodiment] The present invention will be described by way of a preferred embodiment, but it should be understood that there may be variations of the alternatives without departing from the spirit and scope of the invention. Therefore, the details are only exemplified in the description of the present invention, which is used for the purpose of illustration, and may not be used in the scope of the present invention by HP >4丨4. In the present invention, an aliphatic polyurethane foam is exemplified, but an aromatic fluorenyl mercaptoester foam can be used in the present invention.

The present invention is a method for the preparation of a polyurethane-based acid (four) bubble body, which is suitable as a seamless bra enamel, cup, hood top and the like for use in bras and other clothing. The method of the above (4) is particularly suitable for preparing a soft, non-seamless chest cup of soft polyuric acid S-stained sugar produced by reacting with a polyol. The aliphatic polyamino foaming system is U-shaped to give the small cell of the surface #. The rear field (4) is thicker than the thicker portion of the finished bra cup. The molded joint bra cup has a thicker wall at the protruding portion or the tip end portion, and has a thickness smaller than the circumference. The thickness is thick. The sliced aliphatic polyurethane has a foaming sheet placed on the mother mold and a male The red mold of the mold group is classified into Fe1, the domain. The secret of the aliphatic polyglycolic acid is converted into the same shape as that of the gorge. The (4) fat polyamine (tetra) acid bismuth material can be used as a seamless joint. Bra pad [cup, cover and the like for use in solution and other clothing. The molded aliphatic polyurethane _ cover (4) has a better yellowing property than the conventional aromatic bra" and is improved The gas permeability and porosity have an improved body temperature diverging effect. The typical method for producing polyaminophthalic acid vinegar foam is to use the following formulas, including: (1) polyol, (2) water '(3) cross or bond Add '(4) defoaming stabilizer, (1) organometallic catalyst, (6) isocyanic acid vinegar with most functional groups, and (7) various other additives, such as foaming aids, fillers and fire retardants. The specific raw materials used have been used by those who have studied this art. I will not repeat them here. When Ilia commercial urethane foam is used, the two factors are mutually different, which is the main consideration. These two factors are gelling and foaming. (blowing). Gelation refers to the reaction between isoflurane, polyol and crosslinker when ammonia 10 1305540 carboxylic acid ester is produced, and foaming refers to the reaction of isocyanic acid with water to produce carbon dioxide. If the bubble reaction is too fast, or the gelation reaction is too slow, the resulting foam will collapse. Conversely, if the expansion reaction proceeds too slowly, or the gelation reaction is too fast, the foam will form a closed cell structure. The contained cells are filled with hot gas heated by the reaction exotherma. • The resulting foam shrinks and deforms after cooling and aging. - To produce commercial softness with good quality and proper porosity. Polyurethane foam, the balance between the two reactions of gelation and foaming, is controlled by adjusting the content of amine and organometallic catalyst in the reaction composition. The pores or openings are controlled by Ventilation (airf Low) indicates that the amount of ventilation refers to the soft polyurethane foam, which refers to the flow of gas that can pass when a standard pressure difference is applied to the upper and lower sides of a 1.0 吋 thick foam sample. Its unit is cfm, which stands for cubk inchper minute. Detailed test methods are described in ASTM D3574, incorporated herein by reference. Commercially available soft polyurethane foams are generally measured. The ventilation is between 〇·5_4 〇cfm. The lower ventilation volume & body has the danger of s deformation, resulting in waste of materials. Conversely, the foam with too much ventilation produces severe internal cracking (nernerspUt ) 'Or even the entire collapse. Both cause manufacturing problems and waste of materials. The size of the cell in the foam is in the ppi scale, which represents the number of pores per cell (p〇reper. Commercial soft polyurethane) foam usually has a cell size of 20-100 ppi ^ with existing foam The apparatus can be used to produce a polyurethane foam having 3-i4 〇ppi cells. In the present invention, foams having different vesicle sizes and porosity have been evaluated, and accordingly, the air permeability is improved. Thermoformed polyurethane foam bra gasket. It has been unexpectedly found that the gas-based bismuth vinegar foam is reticulated before thermoforming the bra, which greatly improves its gas permeability. For each of the 1305540, that is, the foam having a small ppi value, the small cell size foam may exist, but for the larger cell size, the effect of the improvement is more remarkable. The present invention provides a kind of aliphatic Line_The ideal process for making bra enamels. The vinegar polyurethane foams traditionally made from aliphatic isocyanates have a very closed structure because of this aliphatic isocyanide-reaction surface. The difficult family of polyamino? After the molding, the blistering is broken to break the small cell membrane to increase the ventilation to prevent the foam from shrinking and deforming. This is a relatively paved step. Because the extrusion foaming needs to have sufficient strength in the foam group. It can only be carried out. After the surface, the surface can not be broken immediately, because it is time to rely on _ in the air, its small cell structure art, such as the age of the ruined by its structure, and its surface sister, not (four) line extrusion Broken foam. Commercially extruded foamed foam can usually exhibit aeration of more than α5 gamma, and the axial ventilation is not high enough, but it is enough to prevent shrinkage and deformation of the foam. The small cell film remaining in the foam body, whether for aliphatic or aromatic, causes the porosity of the foam to be significantly reduced after the thermoformation of the polyurethane/foam body. The reason should not be difficult to understand. The small cell film will be--, and the fine air passage will be contained in the foaming body, which results in a significant decrease in gas permeability of the foam after thermoforming. Polyurethane vinegar prepared by the present invention The foam is then subjected to a reticulation process. The unexpected discovery of the invention 'in the hot step _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The shorter model»Laiyue heat. This is the invention of the "heavy scale" because it can process the brain and increase productivity. There are many ways to produce a reticulated hair. The way is to reveal A method of reticulating a woven eye material (e.g., polyurethane foam) of U.S. Patent No. 1, 1, 305, 540, issued to Jan J. Winchcombe et al. 〇mbe invention, the foam sheet is placed between the two pressure plates 'the gas in the closed cells in the sheet is replaced by a blastable gas medium', and the medium is detonated to achieve the foam Meshing. • * Another method of reticulating polyurethane foam is to etch a film with small cells, for example, by immersing the foam in a high-corrosion or strong acid liquid solution, maintaining -set time. The foam was then immersed in clean water several times. A highly heterogeneous or strongly acidic solution will rotate the film along with portions of the surface of the block. Disadvantages of this approach include the removal of all rotched/acidic residues from the finished foam, k being difficult. This residue will cause the finished product to hydrolyze and decompose after several days of reticulation. The foam produced by this method has a limited life span. Another contribution to lowering the molding temperature is an improvement in the working environment. In the thermoforming process of the prior art, the harness set needs to be heated to 35 〇 _45 yesterday. The pressure applied to the polyurethane foam material is about square pairs (to the surface of the mold), and the heat of the poly-based foam material is about 働F. The heat and pressure need to be applied simultaneously for about 6 seconds, and the actual process time varies depending on the thickness of the polyurethane foam φ body. Due to the low thermal conductivity and low porosity of the conventional polyurethane foaming material, if it is a thick foam sheet, a longer process time is required, and the polyurethane foaming material and the shirt can be used at the beginning. The i phase is full of small cell structure Wei. The traditional method is difficult to clear, that is, the condensed gland (biu(8), urea (嶋) and the carboxylic acid bond cleavage in the poly-based formic acid _ material. For the treatment of thicker polyurethane, foaming materials, The long thermoforming process time required to use often leads to a serious problem that 'coffee is in the form of polyurethane__-like materials. These chemical bonds are under the circumstance', thermal decomposition will occur. Toxic hydrogen detection smoke The chemically cleavable bond can be produced 13 1305540. The reticulated polyurethane foam provided by the present invention has improved heat dissipation, so that the temperature in the molding conditions can be lowered to sufficiently improve the thermoforming effect. As a result, It is able to reduce the generation of toxic nitrogen oxynitride fumes. It can reduce the molding temperature. The point B is extremely heavy in the inspection process of the lipopolyamica foam. Carbamate _, its chemical bond strength is less stable than aromatic weiji decanoic acid _ *, so it may decompose even at low temperatures. Therefore, the traditional thermoforming process cannot be applied to molding from yttrium aliphatic isocyanate. Polyurethane foam. However, due to the improvement proposed by the present invention, it is possible to pass a method of molding a polyurethane foam obtained from aliphatic isocyanuric acid. The following examples illustrate the invention 'but the examples are not representative All of the present invention. Examples 1 to 4 Preparation of a foam shown in Table 1 "Foam product prepared according to the present invention" 4. A sample having a thickness of 10 x 10 and a length X width was rolled up.

Stop vacuuming and oxygen into the force The steel has a pressure of about 250 t rr. After injecting oxygen, hydrogen is injected until the internal pressure reaches a maximum of about 650 torr. The composition of the explosive gas is ignited by the Mars device in the pressure cooker. After this step, the sample is inspected. Repeat the above steps. Until all the cell membranes were burned out. The foam samples obtained in each experiment were named as foams 5 to 8, as shown in Table 1. The obtained foams 5-8 were immersed in distilled two gas burners. (methylenechloride) to remove may be due to reticulation The product of the solution. The foam sample was further dried at 5 Torr.
