Problems solved by technology

In the above process steps, there are the following problems: because of the dark and light colors of the fabric, and the unstable factors of the various processes before the brushing, it is difficult to achieve the same brushing style between different colors and different cylinders; in addition, because the brushing machine The vertical tension is relatively large, and the lateral shrinkage of the fabric after brushing will be serious. When setting the brush after finishing, the low-temperature setting shrinkage will not be good. If the high-temperature setting is used, the fastness of the fabric will be affected.
[0004] Therefore, a new brushing process is needed to solve the technical problems of unstable bristle style and unstable shrinkage of flat bristle fabrics

Embodiment 1

[0017] Rough process:

[0018] Step 1: Raw material preparation: 75D / 72F polyester fiber.

[0019] Step 2: Select a warp knitting machine with machine number 28G, adopt mechanical or electronic let-off mode, let-off amount is 1690~1940mm, and the weight of the finished product is 200~300g / m 2 .

[0020] Dyeing and finishing operation:

[0021] Step 3: Blank ring drying process: place the woven fabric in a ring dryer, heat ring drying at 90°C for 30 minutes, cooling time for 5 minutes, and air volume at 75%.

[0022] Step 4: Open-width rolling raising agent process: Put the fabric that has passed step 3 on the setting machine to open-width raising agent, and add 5g / L of raising agent, 30g / L of softener, and 1g / L of penetrating agent to the size tank of the setting machine. L, the temperature of the setting machine is set at 110°C, the speed of the machine is 20 m / min, the air volume is 100%, the door width is set at 110% of the fabric door width obtained in step 3, and the o...

Abstract

A fabric brushing process comprises dyeing and finishing operation and is characterized in that the dyeing and finishing operation comprises the following steps: 1), loop drying of a blank; 2), scutching and rolling with a fuzzing agent; 3), brushing; 4), setting. The fabric brushing process has the following steps: in the fabric brushing process, the steps including blank loop drying, scutching and rolling with the fuzzing agent, high-temperature setting and the like are added, specific processes are optimized, so that the dyelot chromatism is basically avoided for the fabric brushing style, the gram weight is easier to control, and the shrinkage is stable.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a fabric brushing process. Background technique [0002] Brushing is a process step in the textile industry, that is, using a brushing machine to fabric or other objects, by extruding monofilament to create a spiral method or a method of roller rotation, to remove debris on the surface of the fabric or to make the fluff of the fabric More plump and tidy. [0003] At present, when brushing the fabric, it generally includes the following steps: open-width washing, dehydration, high-temperature presetting, high-temperature machine dyeing, dehydration, drying, rolling aids, napping, and resetting; the following steps are also used: rough High-temperature presetting, high-temperature machine dyeing and washing, dehydration, drying, rolling aids, napping, and resetting. In the above process steps, there are the following problems: because of the dark and light colors of ...
