Description
Technical field
The present invention relates to textile technology field, particularly relate to and a kind of directly contact with human body skin, specific function fabric combine, for improving comfort motion bra with health and preparation method thereof.
Background technology
The breast of women is mainly made up of fat and body of gland. The superficial fascia (superficialfascia) of chest wraps up whole breast, and mammary gland tissue and fatty tissue are played a supportive role by Cooper's suspensory ligaments (Cooper ' sligaments) and skin. Size and the weight of adult female's breast vary with each individual. Middle-size and small-size breast wt is less than or equal to 500 grams, and large-scale breast can reach 750 to 1000 grams. Due to the factor of aging and gravity etc., female breast likely can be sagging.
Bra be women for covering and protect the underwear of breast, in actual life, the size of bra is to express with bra size: number refer to the size of under bust girth; Type refers to the size of cup. Between country variant and different production firm, a number type mark for bra is also existed huge difference. But the rule number of being is more big, under bust girth size is more big; Type is more high, and the gap between chest measurement and under bust girth is more big.
Bra is generally divided into following components: cup, braces, shoulder belt and adjustment clasp etc. In the process carrying out sport and body-building, breast can shake and rock, and without wearing bra, chest can significantly swing in spite of oneself so that intramammary elastic fibrous tissue is subject to possible permanent damage, thus causing breast hanging down.
Motion bra, is the class specific function underwear that is avoided that female breast comes to harm in sport and body-building process. The motion bra general type developed for reducing chest to come to harm in motor process at present can be divided into: simple and easy fixed pattern, pressure type fixed pattern and compound structure type. Wherein simple and easy fixed, adopt one layer to have elastic reticulated and fix, simple structure, it is substantially not present the design made for organization of human body, its stationarity is poor.Composite construction formula is then that stationarity is the strongest, and it generally all contains special steel holder, to obtain the support of better support so that fabric intensity is bigger. Pressure type fixed pattern is the type being most widely used; it relies primarily on the elasticity of fabric and forms the pressure to chest and then reach the purpose of fixing breast; it would generally take into full account human engineering on cutting out, thus well fixed being maintained with relative comfortableness obtaining.
At present, in the motion bra of commercial type, the pressure bra with pad is main flow, is subject to liking of women. Such pressure motion bra provides big as far as possible pressure for women so that chest presses close to the main metastomium of women as much as possible, to reach the minimizing chest purpose teetertottered in women sport process as far as possible. But, along with the development of science and technology, it has been found that, not single excessive teetertottering likely destroys mammary gland tissue, and in motor process, long-time excessively compressing chest can destroy mammary gland tissue equally. Pressure bra extrudes chest for a long time, not only cause discomfort and the pain of user, also can oppress the blood circulation in mammary gland and lymphatic circulation, cause blood circulation and lymphsystem that obstacle occurs, long-time use likely can make mammary gland produce pathological changes, such as cause breast tissue downright bad, and then likely develop into breast carcinoma. Additionally, the bra of the type is generally for increasing pressure result, and use the cloth of multilamellar, reduce the moisture absorbing and sweat releasing performance of bra, then user is after perspiration, and perspiration can not be discharged in time, and body surface heat can not distribute in time, the body temperature likely accelerating user rises, and affects the sports achievement of user; Meanwhile, discharging perspiration and accumulate in chest pad part in a large number, chest pad moiety by weight is greatly increased, and can increase the probability that chest rocks in motor process on the contrary. Therefore, people are badly in need of the pressure of a kind of existing appropriateness, can perspire rapidly, can keep the motion bra of chest supporting effect simultaneously.
Patent retrieval finds, the motion bra patent invented both at home and abroad at present is also intended to reduce the motion bra of breast injury in women sport process, focus mostly on as pressure fixing formula motion bra, wherein Chinese patent No.200720173339.7 and No.201320100507.5 utilizes the elastic pressure to chest of different fabric construction, has invented the two different types of bra of motion without steel ring. The former when realizing motion to the strong supporting role of chest while can reach thruster effectively and raise chest mould breast effect; The latter can alleviate when women sport and prevents breast hanging down, absent-mindedness, reaches the fusion of motion body modelling dress and bra. Then by the design of medicated bra part inverted " V " type and the cooperation of elastic cord in US Patent No. P7192333, invent a kind of bra being beneficial in motor process respiratory regulation. Retrieve in result at European patent and show that US201013202217, US201113294899 and US201113072071 etc. are pressure fixing formula motion bra, wherein US201113072071 utilizes a kind of elastomeric material to strengthen the castering action to chest, and then reduces the discomfort in motor process. US201113294899 then constitutes a mounting structures with cladding and disagglutinating action by the bilayer compression fabric of m type and w type. This structure provides three-dimensional cladding, a unsettled and pressure effect plus the elasticity of fabric to chest, and then is applied in motor process, plays the effect of prevention injury of breast. US201113072071 utilizes a kind of elastomeric material, has invented and a kind of has had the motion bra method for designing of its compression of adjustable and cladding breast effect in motor process.
The motion bra of injury of breast in reduction women sport process described in above-mentioned more than one piece publication, mainly through utilizing fabric elasticity, fabric construction and the design of medicated bra privileged sites to realize. Above-mentioned motion bra cannot realize breast displacement under different motion state and stress is controlled, and cannot realize effectively transmission and the function of evaporation chest perspiration in motor process. By literature search, all do not find the bra with above-mentioned functions.
