However, as the requirements of people on ventilation, warmth retention, wearing comfort and other performances are higher and higher, the common outdoor jacket cannot completely meet the requirements of consumers, and more people begin to select soft-shell outdoor jackets.
The soft shell jacket is a garment between the fleece and the jacket, and the fabric is formed by compounding waterproof fabric and fleece fabric, and has the functions of heat preservation, comfort and water resistance and wind resistance. However, the soft shell outdoor jacket on the market at present has the defect that the waterproof performance is reduced due to the performances of heavy warm keeping and the like, so that the waterproof performance requirement of the common outdoor jacket is far not met, the invasion of rainwater and frost and snow can not be effectively blocked, and therefore, the moisture permeates into the inside of the jacket, and the human body feels wet. Therefore, the inventor believes that it is necessary to develop a soft-shell jacket having a high waterproof performance while having a good heat retention property.

In addition, the waterproof finishing agent is used for carrying out waterproof finishing on cotton fibers, bamboo pulp fibers and polyester fibers in the fabric layer, and the waterproof finishing agent is matched with a waterproof layer, so that the synergistic interaction between the waterproof finishing agent and the waterproof layer is fully exerted, and the waterproof performance of the composite fabric is further improved.
The warm-keeping layer of the utility model adopts polar fleece fabric, is softer in contact with human body, and has good ventilation and heat-preserving properties. The cotton fibers are applied to the fabric layer, so that the thickness degree of the fabric layer can be improved, and the windproof and warmth-keeping properties of the fabric layer are enhanced; meanwhile, the moisture absorption and ventilation effects of the fabric layer are enhanced by the aid of the excellent moisture absorption and ventilation performances of the bamboo pulp fibers, so that moisture formed by sweat generated by a human body in outdoor exercises can be discharged rapidly, the moisture cannot be trapped between the human body and clothes, the possibility of losing temperature of the human body in cold weather is reduced, and the warm-keeping effect of the fabric layer is further improved. And this application still adds polyester fiber in the surface fabric layer, utilizes polyester fiber lower coefficient of heat conduction for the heat of surface fabric layer is difficult for losing, and then has strengthened the heat preservation effect of surface fabric layer, has compensatied cotton fiber coefficient of heat conduction higher defect, has reduced cotton fiber's quantity, makes the surface fabric layer can not be too heavy, makes things convenient for the human body to carry out outdoor activities.
In summary, the cotton fiber, the bamboo pulp fiber and the polyester fiber are mixed and matched for use, the synergistic effect among the cotton fiber, the bamboo pulp fiber and the polyester fiber is fully exerted, and the cotton fiber, the bamboo pulp fiber and the polyester fiber are matched with the thermal insulation layer, so that the composite fabric layer has stronger ventilation and thermal insulation properties and is lighter; meanwhile, the waterproof finishing agent is adopted to carry out waterproof treatment on the fabric layer, and a synergistic effect is exerted with the waterproof layer, so that the waterproof performance of the composite fabric is further improved, and the composite fabric has stronger heat preservation performance and stronger waterproof performance.
