Description
Technical Field
The invention relates to the technical field of preparation of down feather flocculus, in particular to a down feather flocculus, and a preparation method, a processing device and an application method thereof.
Background
At present, along with the rapid development of social economy, the requirements of people on life quality are higher and higher, and especially in the selection of winter warm-keeping clothes, consumers prefer light-weight, comfortable and good warm-keeping down coats compared with cotton coats. Currently, down jackets are generally composed of three parts: surface cloth, down-filled liner cloth and lining cloth. The most important and complicated process in the production process of the down jacket is to carry out manual or mechanical down filling on the liner cloth in a cloth bag shape. Based on the characteristics of light weight, fluffiness and easiness in floating in the air of the down feather, the process difficulty of filling the down feather into the liner cloth is higher, and the production efficiency of a factory is limited to a certain extent.
Need observe the weight value of electronic scale when filling the fine hair in the manual work to reach the fine hair volume of filling of standard, then seal the processing to the courage cloth after filling the fine hair, but this process is not only loaded down with trivial details slowly, has higher requirement to workman's proficiency in addition at speed, in order to guarantee the production efficiency of mill, needs higher cost to hire the manual work, and then leads to manufacturing cost too big. In addition, the scattered and soft characteristic of down feather can cause larger dust in a down feather filling workshop, even if a user wears the mask, the user can cause adverse reactions such as skin allergy and the like, and certain harm is caused to the health of the user. Although the production efficiency of the mechanical down filling machine is improved, the down filling amount is not manually accurate, certain errors exist, in addition, the floor area of the down filling machine and the expensive expense of the machine per se cause the factory to increase extra large capital investment, and the down filling machine is not cost-effective in economic cost.
Aiming at the problems, the better solution method is to fix the down feather into the flocculus, thereby simplifying the down feather filling process, directly sewing the down feather by the liner cloth, and improving the production efficiency on the premise of ensuring various characteristics of the clothes through subsequent processing treatment. However, in the prior art, the down feather is processed into the flocculus on the premise of changing the original characteristics of the down feather, so that the original performance of the down feather is seriously influenced, and the problem cannot be fundamentally solved.
For example, the invention patent with application number CN201010128249.2 discloses a three-layer sandwich type composite down feather flocculus and a manufacturing method thereof. The method adopts a three-layer composite lapping method by utilizing hot-melt fibers. The invention patent with the application number of CN201210144820.9 discloses a processing method of a multi-layer composite sizing down feather flocculus. Mixing down fibers and low-melting-point fibers by a mixer to respectively prepare a high-down-content mixture and a low-down-content mixture; then, opening, carding, lapping, needling and reinforcing, and carrying out hot melt adhesion and reinforcement to obtain the composite shaped down feather flocculus.
Although the down feather is fixed into the wadding sheet by the method, the subsequent process of sewing (down filling) the liner cloth is facilitated, the down feather wadding sheet prepared by the method seriously influences the filling power and the heat retention of the down feather, so that the weight of down-filled clothes is increased while the original ecological space structure of the down feather is lost, and the hand feeling and the heat retention of the clothes are reduced.
In view of the above, there is a need to design an improved method for fixing down feather into a wadding sheet to facilitate filling down feather without affecting the superior properties of the down jacket, so as to solve the above problems and meet the production requirements of enterprises.
