Problems solved by technology

[0009] However, the shape of the parabolic interlayer cavity in this device is complex and difficult to process. During the manufacturing process, the requirements for the flatness of the steel plate and the precision of processing are relatively high, which may easily cause errors. If the applicator cannot be processed according to the ideal shape, the cavity may be caused. Inconsistent foam residence time in the body, which can eventually lead to uneven foam application
[0010] Chinese patent ZL 200710047713.3 is a method of transporting the foam to the foam application part composed of multiple parabolas through the distribution part by using multiple pipes of equal length. The application of products running on a plane without curling in the horizontal direction can ensure the uniform application of foam. However, this patent cannot solve the problem of curling of knitted fabrics, thus limiting the application of foam in knitted fabrics.
[0011] It can be seen from the above that in order to solve the problems of high liquid retention rate, high energy consumption and low productivity in the process of traditional knitted fabric processing, such as pretreatment, dyeing, finishing and printing, foam processing is a relatively effective way. For this reason, there must be a foam application device that can create a uniform tension on the knitted fabric and at the same time apply the foam evenly to the knitted fabric without being affected by the fabric hemming problem

Embodiment Construction

[0047] The specific implementation of the present invention is described by taking the finishing process of knitted fabrics as an example. The traditional knitted fabric finishing process is: fabric opening, padding, stacking, and drying. The invention can combine the fabric opening and padding, and apply foam to the fabric before the fabric is opened, and solve the problem of uneven padding treatment caused by the curling of the fabric after opening.

[0048] Such as Figure 1a-1cAs shown, the foam applicator 10 of the first embodiment of the present invention includes a foam manifold 11 , a foam distribution device 12 , a foam applicator 13 and a support 14 . One end of the foam main pipe 11 is connected to a foam generator (not shown in the figure), and the other end is connected to a foam distribution device 12 . In this embodiment, the foam distribution device 12 is conical, and a foam flow channel 120 is formed inside it. The foam delivery main pipe 11 is located abov...

Abstract

The invention discloses a foam application device for a knitted fabric. The device comprises a foam main pipe, a foam distribution part, a foam application part and a support body, wherein the foam distribution part is communicated with the foam main pipe, and a foam flow passage is formed in the foam distribution part; the foam application part is communicated with the foam distribution part and provided with an outlet; and the outlet of the foam application part is an integrally circular slit and is close to the peripheral surface of the support body, and the length of the path between the foam main pipe and any point on the circumference of the circular outlet is equal. By adopting the application device of the invention, the fabric can be finished before scotching, the tension of the treated fabric is uniform, and hemming is avoided. The path of the foam flow passage in the foam distribution part is kept equal, so the foam attenuation degree is consistent, and the treated degree of each part of the fabric is uniform.

Description

technical field [0001] The invention relates to a device for applying chemicals in the process of knitting printing and dyeing, in particular to a device for applying foam to knitted fabrics. Background technique [0002] Traditional knitting printing and dyeing processing, including pretreatment, dyeing, finishing and printing processing, requires the cylindrical knitted fabric to be opened first (that is, cut into a flat shape) and then subsequently applied with chemicals or liquids. For example, in the finishing process of knitted fabrics, the fabric after opening width is soaked in the immersion tank, and then the excess chemicals are squeezed out of the fabric through the paddle car. It is easy to curl under the action, and the problem of uneven rolling rate of fabric caused by fabric curling cannot be completely solved in the current traditional production process. However, the high amount of liquid carried by the fabric caused by the rolling machine is generally 50%-...
