Description
[technical field]
The present invention relates to trampoline net technical field, specifically, is a kind of processing method of trampoline net.
[background technology]
Current outdoor exercises just develop towards both direction: a class is " little open air ", poly-talented outdoor exercises, by Challenging the Limits, go beyond oneself for the purpose of; Another kind of, be that popular type is outdoor, i.e. general outdoor exercises, advocate the harmony between man and nature, merge, realize body aroused in interest happy out of doors with the Nature.And bringing the abundant of material and cultural life, outdoor exercises along with the economic development of China, especially popular type outdoor exercises are pursued being subject to more and more people pursuing healthy living.
" family is outer " this concept is popularized abroad already in fact.Just often so warm picture can be seen: whenever weekend or holiday from external film, TV play, family of three just opens caravan dress leisure, bring that the equipment such as oven, tent, sleeping bag is encamped to Urban Parks or field, BBQ, allow child contact and understand the Nature whereby, in atmosphere easily, also promote the emotion between household simultaneously.
Although the outdoor exercises in units of family carry out still backwardness relatively in China, but some outdoor goods business takes the lead in starting at home the concept introducing " family's outdoor leisure ", be proposed the relevant outdoor exercises equipment be the theme with family, have specially for man and wife two people, three-person household and have old man family and the camping suit of design, the lovers, household's outdoor leisure clothes etc. of pattern assortment, outdoor battalion is just devoted to this theory to be extended through in every a product, wish, for each consumer, to create different outdoor new experience.
Outdoor clothes and other equipments are feature, scope, intensity etc. according to different outdoor activities, made, to tackle various outdoor environment, allow user feel at ease to enjoy outdoor experience by particular design and production technology.Health at the volley can activity freely, not by the limitation and restriction of clothes; Meet the wear-resisting requirement in motion, large area and the wear-resisting of local all will embody to some extent on clothes; Clothes to there is the pocket bag being applicable to motion needs, can carry-on articles be placed, can not motion be hindered again; The design-adjustable of local can allow outdoor exercises more freely; In addition, in order to the multiple demand in satisfied motion, some clothes also will have multiplely wears method.
For guaranteeing the functional of outdoor clothes, the fabric of use is wanted soft comfortable, is had certain elasticity, stiffening, ventilative moisture absorption, wear-resisting solid and have wind-proof performance.Along with the progress and development of science and technology, the perfect combination of what outdoor clothes finally will realize is function, volume, weight and fashion, namely by the cutting of technique, the design of lines and fabric select under the prerequisite of satisfied outdoor function, volume is accomplished minimum, total amount is accomplished the lightest, and combines with fashion.
Outdoor clothes be not only climbing the mountain, on foot etc. outdoor exercises time just wear, and also to wear in daily life.And in the fashion of color, design, can be more and more less with the difference of business suit.The combination of the functional and fashion of outdoor clothes will be more and more tightr.
Outdoor exercises are never only individual to naturally conquering and exploring, and the challenge to the self-limit, it also can be play open air with household one, common impression, mutually shares the pleasurable experiences that outdoor exercises bring, and this joyful friend passing to surrounding.
2009 " Bedjump ", runs away rapidly in website, and Chinese is translated into " trampoline " or " trampoline ".Numerous fan growing tender of this motion is had in all parts of the world.Fan can select the bed of good springiness (being more often the large bed in hotel) usually, jumps up, makes various action aloft, then the excellent photo upload captured to blog or accept on the website of picture uploading.The pure online friends of intention utilize this chance to give full play to the imagination of powerful and unconstrained style, and jump appearance, express one's feelings very strange, the excitement levels of participation is not second to participating in an extreme sport.
Existing worldwide jumping trampoline, spring trampoline, limit of can being in sees that TV limit is taken exercise, and parent-child jumps together, and exercise is lightened pine, and what allow family atmosphere become is more perfect, and be that in applicable family room, amusement and leisure body-building is used: children increase, U.S. leg of losing weight of being grown up, carries stern; From amount of exercise, continue jumping 15 minutes, and to jog 30 minutes or to jump Fitness Dance 20 minutes very nearly the same, be consuming time less, large aerobic exercise of consuming energy.
Along with China motion valiant fighter constantly snatching a gold medal on trampoline and trampoline project in 2008 and 2012 Olympic Games, such as champion He Wenna in 2008, Olympic champion Dong Dong and He Wenna of 2012 refights the Olympic Games of 12 years, the also welcome degree of its China will improve constantly, and expand the market of product.
And functional trampoline net becomes current trend.
