Abstract
Description
Technical Field
[0001] This utility model relates to dyeing and printing equipment, and more particularly to a high-efficiency continuous polyester / viscose synthetic fiber brushed fabric pre-shrinking and whitening device. Background Technology
[0002] Polyester-viscose synthetic fiber brushed fabric is an important raw material for the production of bedding. When printing on polyester-viscose synthetic fiber brushed fabric, the raw fabric needs to be pre-shrinked and whitened first. At present, the pre-shrinking and whitening of polyester-viscose synthetic fiber brushed fabric is mainly carried out by a high-temperature overflow machine. Liquid containing whitening material is added to the high-temperature overflow machine, and then the polyester-viscose synthetic fiber brushed fabric is circulated in a loose state under high temperature and high pressure through the high-speed flow of the solution, and the fabric is whitened at the same time. After that, the fabric is dried and set by a setting machine in a single-layer loose manner, while whitening and color development. Currently, high-temperature overflow machines are used for pre-shrinking and whitening treatment. To ensure the fabric circulates in a natural floating state, a high liquid ratio, high treatment temperature, high pressure inside the container, and long high-temperature heat preservation time are employed. In addition, the heating and cooling time makes the entire process time-consuming, water-intensive, energy-intensive, wastewater-intensive, and highly polluting. The high-temperature and high-pressure overflow machine container is dangerous and inefficient. After treatment, the warp shrinkage rate of the polyester / viscose synthetic fiber brushed fabric is small, affecting the hand feel and fullness of the polyester / viscose synthetic fiber brushed fabric. Furthermore, due to the influence of the concentration of whitening material in the solution inside the overflow machine and the fabric speed on the setting machine, the whitening and color development time is insufficient, resulting in a low whiteness value and poor whitening effect of the treated polyester / viscose synthetic fiber brushed fabric. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a high-efficiency continuous polyester / viscose synthetic fiber brushed fabric pre-shrinking and whitening device with short pre-shrinking and whitening processing time, low water consumption, low energy consumption, low risk, high warp and weft shrinkage rate and good whitening effect.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a high-efficiency continuous polyester / viscose fiber brushed fabric pre-shrinking and whitening device, comprising a polyester / viscose fiber brushed fabric feeding device, a padding device, a high-temperature treatment device, and a polyester / viscose fiber brushed fabric receiving device arranged in sequence; the high-temperature treatment device is provided with a guide carrier that moves from the feeding end to the output end under the drive of the guide driving device, and the feeding end of the high-temperature treatment device is provided with a traction dropping device that stacks the polyester / viscose fiber brushed fabric after padding by the padding device onto the moving guide carrier.
[0005] As a preferred technical solution, the high-temperature treatment device includes a high-temperature oven, a heating device is provided inside the high-temperature oven, a fabric inlet is provided at the inlet end of the high-temperature oven, a fabric outlet is provided at the outlet end of the high-temperature oven, and the guiding carrier passes through the inlet, the inner cavity of the high-temperature oven and the outlet in sequence.
[0006] As a preferred technical solution, the guiding carrier is a guiding cloth, and the guiding driving device includes driving chains respectively arranged on both sides of the guiding cloth on a high-temperature oven. The driving chains are respectively provided with cloth clamping devices for clamping the cloth edges on both sides of the guiding cloth. The high-temperature oven is provided with a power device that drives the two driving chains to move synchronously and drives the guiding cloth from the cloth inlet end to the cloth outlet end.
[0007] As a preferred technical solution, the guiding carrier is a chain plate or a needle plate, and the high-temperature drying oven is equipped with a power device that drives the chain plate or needle plate to move and guide the fabric from the infeed end to the outfeed end.
[0008] As a preferred technical solution, the infeed end of the high-temperature drying oven is provided with a guide fabric unwinding device, and the outlet end of the high-temperature drying oven is provided with a guide fabric winding device.
[0009] As a preferred technical solution, the traction and fabric dropping device includes a traction roller rotatably mounted on a bracket at the fabric inlet end of a high-temperature drying oven located above the guide carrier. A pressure roller parallel to the traction roller is rotatably mounted on the upper side of the traction roller. The two ends of the pressure roller are slidably mounted on the bracket. A pressing drive device for pushing the pressure roller to press the traction roller is also provided on the bracket. The traction roller is driven by the traction drive device.
[0010] This invention, employing the aforementioned technical solution, involves the polyester / viscose synthetic fiber brushed fabric being rolled by a rolling device and then continuously stacked into a high-temperature drying oven. During this process, it undergoes pre-shrinking and whitening treatment by being kept heated. The amount of rolling solution is small, the concentration of whitening agents in the solution is high, and the fabric is dried in a stacked state within the high-temperature oven, allowing sufficient time for whitening and color development, which is beneficial for fabric whitening. The resulting fabric exhibits excellent whitening effect and high whiteness. Furthermore, it significantly reduces water consumption, wastewater, and pollution. The entire pre-shrinking and whitening process is short and efficient, avoiding the waste of heat and electricity required by heating large amounts of liquid in overflow pre-shrinking machines. The pre-shrinking and whitening process of this invention is carried out under normal pressure, reducing the risk of accidents. Moreover, the polyester / viscose synthetic fiber brushed fabric is stacked on a guide carrier within the high-temperature oven, free from external tension. It undergoes high-temperature pre-shrinking and gradual drying while still wet, resulting in high warp and weft shrinkage rates, a soft hand feel, high fullness, and a strong wool-like texture, making it ideal for use in the production of bedding after printing.

Detailed Implementation
[0013] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, in the drawings, the same reference numerals are assigned to components that are substantially the same in structure and function, and redundant descriptions of substantially the same components have been omitted to make the description more concise.
[0014] like Figure 1 and 2 As shown, a high-efficiency continuous polyester / viscose fiber brushed fabric pre-shrinking and whitening device includes a polyester / viscose fiber brushed fabric feeding device 4, a padding device 5, a high-temperature treatment device 6, and a polyester / viscose fiber brushed fabric taking device 7 arranged in sequence. The high-temperature treatment device 6 is equipped with a guide carrier 2 that moves from the feeding end to the output end under the drive of a guide device. The feeding end of the high-temperature treatment device 6 is equipped with a traction and dropping device that drops and stacks the polyester / viscose fiber brushed fabric 1 after padding by the padding device 5 onto the moving guide carrier 2.
[0015] like Figure 2 As shown, the high-temperature treatment device 6 includes a high-temperature oven 3, inside which a heating device 8 is installed. The high-temperature oven 3 has a fabric inlet at its inlet end and a fabric outlet at its outlet end. The guide carrier 2 passes sequentially through the inlet, the inner cavity of the high-temperature oven 3, and the outlet. The heating device 8 can use commonly used high-temperature steam or thermal oil to heat the air via a radiator, or directly heat the air using natural gas or electric heating. The heated high-temperature air is then blown into the high-temperature oven 3 by a circulating fan. This structure of the heating device 8 is commonly used in the dyeing and printing industry and will not be described in detail here.
[0016] like Figure 2As shown, the guiding carrier 2 is a guiding fabric, and the guiding driving device includes driving chains respectively arranged on both sides of the guiding fabric on the high-temperature oven 3. Each driving chain is equipped with a fabric clamping device for holding the fabric edges on both sides of the guiding fabric. The high-temperature oven 3 is equipped with a power device that drives the two driving chains to move synchronously, propelling the guiding fabric from the inlet end to the outlet end. The driving chains are mounted on the high-temperature oven 3 via sprockets. The power device can be a motor that drives the sprockets through a speed-changing mechanism to drive the chains. The fabric clamping device adopts the structure of the fabric clamping device on the setting machine commonly used in the dyeing and printing industry, and is a common component, which will not be described in detail here. The guide carrier 2 can also be a chain plate or a needle plate. The high-temperature oven 3 is equipped with a power device that drives the chain plate or needle plate to move and guide the fabric from the inlet end to the outlet end. The chain plate or needle plate is connected to the chain at both ends. The power device can also be a motor. The motor drives the transmission sprocket of the speed change mechanism to drive the two chains to move synchronously.
[0017] like Figure 2-5 As shown, the high-temperature drying oven 3 is equipped with a guide fabric unwinding device 9 at the fabric inlet end and a guide fabric winding device 10 at the fabric outlet end. The guide fabric unwinding device 9 and the guide fabric winding device 10 can be fabric unwinding and winding devices commonly used in the fabric processing of the dyeing and printing industry. Similarly, the polyester / viscose synthetic fiber brushed fabric inlet device 4, the padding device 5, and the polyester / viscose synthetic fiber brushed fabric winding device 7 can also be unwinding and winding equipment commonly used in the fabric processing of the dyeing and printing industry. These are all commonly used and well-known equipment in this industry and will not be described in detail here.
[0018] like Figure 2 and Figure 5 As shown, the traction and fabric feeding device includes a traction roller 12 rotatably mounted on a bracket 11 above the fabric feeding end of a high-temperature drying oven 3, located above the guiding carrier 2. A pressure roller 13, parallel to the traction roller 12, is rotatably mounted on the upper side of the traction roller 12. The two ends of the pressure roller 13 are slidably mounted on the bracket 11. A pressing drive device 14 is also mounted on the bracket 11 to push the pressure roller 13 to press against the traction roller 12. The pressing drive device 14 can be two hydraulic cylinders mounted on the bracket 11. The roller shafts at both ends of the pressure roller 13 are rotatably mounted on sliders. The bracket 11 has a slide rail for the two sliders to slide up and down. The plungers of the two hydraulic cylinders are respectively connected to the two sliders. The traction roller 12 is driven by a traction drive device 15, which can be a motor that drives the traction roller 12 to rotate via a chain and sprocket speed change mechanism. To enhance the traction force on the polyester / viscose synthetic fiber brushed fabric 1, the surfaces of the traction roller 12 and the pressure roller 13 can be covered with a rubber layer.
[0019] When using this high-efficiency continuous polyester / viscose fiber brushed fabric pre-shrinking and whitening device, the guide fabric on the guide fabric unwinding device 9 is unwound and guided to the high-temperature oven 3. Under the drive of the guide driving device, it passes through the inlet, the inner cavity of the high-temperature oven 3 and the outlet in sequence, and is then wound onto the guide fabric winding device 10. Meanwhile, the polyester / viscose fiber brushed fabric 1 is unwound from the polyester / viscose fiber brushed fabric inlet device 4 and guided into the padding device 5 for padding. After padding, the polyester / viscose fiber brushed fabric 1 is guided to the traction roller 12 and the pressure roller 13 to drop and stack onto the guide fabric. The traveling guide fabric is continuously and slowly introduced into the high-temperature oven 3 from the inlet for high-temperature pre-shrinking and whitening and coloring treatment and gradually dried. Then, the treated polyester / viscose fiber brushed fabric 1 is continuously and slowly led out of the outlet by the guide fabric and wound by the polyester / viscose fiber brushed fabric winding device 7.
[0020] Because the whitening material for the polyester / viscose fiber brushed fabric 1 of this invention is impregnated into the fabric through padding, unlike the natural floating soaking method in a high-temperature overflow machine, the whitening material concentration is higher during padding. Furthermore, the fabric is dried in a stacked state in the high-temperature oven 3, allowing sufficient time for whitening and color development, which is beneficial for whitening the polyester / viscose fiber brushed fabric 1. The required liquid and water volume is significantly less than that of a high-temperature overflow machine, thus reducing water consumption and wastewater discharge, resulting in less pollution. It also avoids the significant time and energy consumption associated with heating the liquid in a high-temperature overflow machine, leading to high efficiency and low energy consumption. Moreover, the entire process of this invention is carried out under normal pressure, minimizing the risk. The polyester / viscose fiber brushed fabric 1 is stacked on the guide carrier 2 in the high-temperature oven 3, without external tension, and undergoes high-temperature pre-shrinking and gradual drying in a wet state, resulting in a high warp and weft shrinkage rate.
