Description
Technical field
The present invention relates to textile technology field, particularly relate to and a kind ofly directly to contact with human body skin, combined by specific function fabric, for improving motion brassiere of comfort and health and preparation method thereof.
Background technology
The breast of women is mainly made up of fat and body of gland.The fascia superficialis (superficialfascia) of chest wraps up whole breast, and Cooper's suspensory ligaments (Cooper ' s ligaments) and skin play a supportive role to breast tissue and adipose tissue.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.
Brassiere be women for covering and protect the underwear of breast, in actual life, the size of brassiere is expressed with bra size: the size number referring under bust girth; Type refers to the size of cup.Between country variant and different production firm, huge difference is also existed to a number type mark for brassiere.But the rule number of being is larger, under bust girth size is larger; Type is higher, and the gap between chest measurement and under bust girth is larger.
Brassiere is generally divided into following components: cup, braces, shoulder belt and adjustment clasp etc.In the process of carrying out sport and body-building, breast can shake and rock, if do not wear brassiere, chest can significantly swing in spite of oneself, makes intramammary elastic fibrous tissue be subject to possible permanent damage, thus causes breast hanging down.
Motion brassiere is the specific function underwear that a class can avoid female breast to come to harm in sport and body-building process.At present for the motion brassiere general type that minimizing chest comes to harm at motion process and develop can be divided into: simple and easy fixed, pressure type fixed and compound structure type.Wherein simple and easy fixed, adopt one deck to have flexible reticulated and fix, there is not the design made for organization of human body in simple structure, its stationarity poor substantially.Composite construction formula is then that stationarity is the strongest, and it generally all contains special steel holder, supports, make fabric intensity larger to obtain better support.Pressure type fixed is the type be most widely used; it mainly relies on the elasticity of fabric and is formed the pressure of chest and then the object reaching fixing breast; it usually can take into full account ergonomics on cutting out, thus is obtaining well fixedly keeping relative comfortableness simultaneously.
At present, in the motion brassiere of commercial type, the pressure brassiere of band pad is main flow, is subject to liking of women.Such pressure motion brassiere provides pressure large as far as possible for women, makes chest press close to the main metastomium of women as much as possible, reduces the object that teetertotter of chest in women sport process as far as possible to reach.But along with the development of science and technology, it is found that, not single excessive teetertottering likely destroys breast tissue, in motion process, long-time excessively compressing chest can destroy breast tissue equally.Pressure brassiere extrudes chest for a long time, not only cause discomfort and the pain of user, also can oppress the blood circulation system in mammary gland and lymphatic circulation, blood circulation system and lymphatic system is caused to occur obstacle, long-time use likely can make mammary gland produce pathology, such as cause breast tissue downright bad, and then likely develop into breast cancer.In addition, the brassiere of the type generally for increase pressure result, and use the cloth of multilayer, reduce the moisture absorbing and sweat releasing performance of brassiere, so user is after perspiration, sweat 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, discharge sweat and accumulate in chest pad part in a large number, chest pad moiety by weight increases greatly, can increase the possibility that chest rocks in motion process on the contrary.Therefore, people are badly in need of a kind of pressure of existing appropriateness, and energy perspire rapidly, can keep the motion brassiere of chest supporting effect simultaneously.
Find in patent retrieval, the motion brassiere patent of having invented both at home and abroad at present is also intended to reduce the motion brassiere of breast injury in women sport process, focus mostly on as pressure fixing formula motion brassiere, wherein Chinese patent No.200720173339.7 and No.201320100507.5 utilizes different fabric construction elasticity to the pressure of chest, has invented two dissimilar without steel ring motion brassiere.The former when realizing motion to the strong supporting role of chest while can reach thruster effectively and raise chest mould chest effect; The latter can alleviate when women sport and prevents breast hanging down, and absent-mindedness, reaches the fusion of motion body modelling dress and brassiere.Then by falling the design of " V " type and the cooperation of elastic cord in brassiere part in US Patent No. P7192333, invent a kind of brassiere being beneficial to respiratory regulation in motion process.In European patent result for retrieval, show US201013202217, US201113294899 and US201113072071 etc. be pressure fixing formula motion brassiere, wherein US201113072071 utilizes the castering action of a kind of elastomeric material enhancing to chest, and then reduces the discomfort in motion process.US201113294899 then forms one by the bilayer compression fabric of m type and w type and has mounting structures that is coated and disagglutinating action.This structure adds that the elasticity of fabric provides coated, the unsettled and pressure effect of three-dimensional to chest, and then is applied in motion process, plays the effect of prevention injury of breast.US201113072071 utilizes a kind of elastomeric material, has invented a kind of motion brassiere method for designing with its compression of adjustable and coated breast effect in motion process.
The motion brassiere of injury of breast in reduction women sport process described in above-mentioned more than one piece publication, realizes mainly through utilizing the designs of fabric elasticity, fabric construction and brassiere privileged sites.Above-mentioned motion brassiere cannot realize breast displacement under different motion state and stress controlled, and cannot realize effectively transmitting in motion process and the function of evaporation chest sweat.By literature search, all do not find the brassiere with above-mentioned functions.
