Description

Continuous open-width fiber-removing poaching device for water-soluble fiber companion-spun fabric

Technical Field

The utility model relates to a special water boiling device for open-width fiber removal of a fabric formed by water-soluble fiber companion spinning, and belongs to the field of fabric finishing equipment.

Background

The yarn count refers to the thickness degree of the yarn, and the higher the yarn count is, the thinner the yarn is, generally speaking, the softer the fabric is, and the higher the fabric is; however, the thinner the yarn, the lower the strength of the yarn, and the more easily the yarn breaks, which is more difficult to be used for weaving the fabric, due to the limitation of the mechanical properties of the raw materials. Under the premise, a companion spinning process is provided, namely water-soluble fiber and common fiber are blended, then the blended fiber is woven into yarn with low yarn count, and then the yarn is woven into fabric, and in the process, the weaving difficulty of the fabric is low due to the fact that the yarn is thick; after the fabric is formed, the fabric is subjected to after-treatment, and water-soluble fibers in the fabric are removed by using a solvent, so that the thickness of yarn is reduced, the fabric with high yarn count is formed, the yarn count of the fabric is increased, and the grade of the fabric is improved. Since the water-soluble fiber commonly used in the prior art is vinylon (the trade name of polyvinyl acetal fiber is also called vinylon and is not resistant to hot water), the process of increasing the yarn count by finishing the fabric is also called 'vinylon removal' (vinylon removal).

The post-finishing of the water-soluble fiber companion-spun fabric is mainly to put the fabric into hot water (above 80 ℃) and dissolve the companion-spun water-soluble fiber through continuous washing action. This after-treatment, the conventionality is to use the cylinder rinsing machine, twine the surface fabric on the spool, then add hot water, heat to dissolving temperature after, roll repeatedly, through the rotation of spool, soak, erode the surface fabric by hot water repeatedly to dissolve water-soluble fibre. However, since the fabric needs to be wound on a reel, after repeated washing with hot water, although the water-soluble fiber is dissolved, the fabric itself is also prone to wrinkle, which results in limited application of the fabric or requires complex wrinkle removal treatment.

Here, by referring to the circulation continuous boiling process mentioned in the open width fiber removing method of chinese patent publication No. CN102134794A, the preparation method of titanium-containing fiber cool home textile fabric of chinese patent publication No. CN113089164A, and the process and equipment for removing fiber from fabric mentioned in the prepared fabric, the fabric is spread and then passed through a water tank in an open width state to be removed; although the method mentions open-width fiber removal, the problem that the fabric is easy to wrinkle in the traditional roller washing fiber removal process is solved; however, in the whole dimension removing process, either multiple times of boiling and storage are needed, the time span reaches several days, or single open-width poaching is needed for 30-40min, the water boiling box is needed to be stayed in for a long time, and the dimension removing process is only suitable for small-scale intermittent production and cannot meet the requirement of continuous production.

For the water-soluble fiber companion spinning fabric, the subsequent finishing step needs to be improved, the continuous production requirement is met, and the production efficiency is improved.

The method is applied to the fiber removing treatment of the water-soluble fiber companion spinning fabric to obtain the high-count fabric; in order to realize continuous production, the basic structure of the whole set of production equipment is shown in figure 1 and comprises a cloth placing mechanism 1, a 1 st water tank 2, a 2 nd water tank 3, a 3 rd water tank 4, a cleaning tank 5 and a cloth collecting mechanism 6; the continuous open-width fiber-removing poaching device for the water-soluble fiber companion-spinning fabric comprises the No. 1 water tank 2, the No. 2 water tank 3, the No. 3 water tank 4 and corresponding accessory parts.

The cloth placing mechanism 1 is used for erecting the whole roll of fabric or introducing the whole basket of open width fabric into equipment, and guiding the fabric to a subsequent device through a traction roller 11. The traction roller 11 can be a spreading roller with herringbone convex patterns, and the fabric is unfolded from the middle to two sides in the rotating process, so that the fabric is flattened.

The continuous open-width fiber-removing poaching device for the water-soluble fiber companion-spun fabric is characterized in that a plurality of guide wheels are arranged in a No. 1 water tank 2, a No. 2 water tank 3 and a No. 3 water tank 4, the fabric is folded back and led through, the length of the fabric in the water tanks is prolonged, the contact time of the fabric and a water bath is prolonged, and the water-soluble fiber is fully heated, absorbed and dissolved; wherein, the 1 st water tank 2, the 2 nd water tank 3 and the 3 rd water tank 4 are internally provided with heating devices, the water temperature is controlled to be about 95 ℃, the better temperature is 98 ℃, the boiling point of the water is slightly lower than the melting point of the water-soluble fiber, and the melting point of the water-soluble fiber is higher than the melting point of the water-soluble fiber, so that the water-soluble fiber is easier to dissolve.

In the preparation stage, when the water temperature is low, the water tank is heated by adopting a direct steam heating mode, high-temperature steam is directly introduced into the water tank, the heating speed is high, and the steam is sprayed into the water tank to stir the water in the water tank, so that the water temperature of each part is more uniform; treat that the temperature reaches the setting value, after the start-up processing, adopt the indirect heating mode of steam to heat, coil cloth steam pipe way in the basin, fill into steam in the pipeline, steam moves in the pipeline, heats the heat preservation to the water in the basin, and it heats steadily, and the water in the basin can not seriously be mixd in the heating process, avoids the steam to directly spout the surface fabric, reduces impact and the disturbance to the surface fabric, avoids the surface fabric to take place the fold in the disturbance under high temperature. The utility model adopts the modes of direct and indirect heating of steam and mixed heating, thereby improving the energy utilization efficiency of the steam.

The No. 1 water tank 2 is a fiber primary dissolving water tank, and in the water tank, as the fabric is just in contact with hot water, the fabric is mainly in the stages of temperature rise and water absorption, and fibers which can be melted in the water bath are less.

The No. 2 water tank 3 is a fiber deep dissolving water tank, and in the water tank, the fabric is fully contacted with hot water to start main water soluble fiber separation; here, the length of the 2 nd water tank 3 may be increased so that the fabric stays therein for a sufficient time to sufficiently dissolve the water-soluble fiber therein. In the water tank, the fiber content in the water bath is high, and the concentration of the water solution is high.

The 3 rd water tank 4 is a transition water tank, the fabric supplied is processed by the 2 nd water tank, and then the residual water-soluble fiber is dissolved, and the fabric is cleaned and finished. In the water tank, the content of the fiber melted in the water bath is low, and the concentration of the water solution is low.

Because the water tanks are long and water can generate certain resistance to the running of the fabric, the 3 water tanks are internally provided with active driving rollers which are connected with driving motors to drive the conveying of the fabric; however, as the 3 water tanks are independently arranged, if the fabric conveying speeds in the 3 water tanks are inconsistent, the fabric is easily stretched; the water tank is a heating water tank, the strength of the basic yarn fiber is reduced after the basic yarn fiber absorbs water, once the basic yarn fiber is stressed and stretched for a long time, the stretching is easy to cause, the flatness of the fabric is influenced, unrecoverable wrinkles are caused, and even yarn breakage and fabric damage are caused. Therefore, a governor 7 is required between the adjacent water tanks.
