The processing technology of the ice-cold-imitating hand feeling fabric can effectively reduce the cost, has hydrophilicity and good printing effect, and is not easy to produce silicon oil stain.

However, in the two inventions, the amount of the auxiliary agent added in the formula is large, and a large amount of antibacterial agent is also added in CN102517904A, which affects the hand feeling of the finally obtained fabric, so that the fabric is not stiff and smooth enough, and the finished fabric has no draping feeling and smoothness and needs further modification and post-finishing process.

Disclosure of Invention

The invention aims to solve the problems of poor hand feeling, high cost and poor production stability of the fabric in the prior art by aiming at the fabric after-finishing process, and provides the fabric after-finishing process with cool and smooth hand feeling, low additive amount of an auxiliary agent, low cost, less cloth cover flaws and good hand feeling.

In order to achieve the purpose, the invention adopts the technical scheme that:

an after-finishing process of fabric with cool and smooth hand feeling comprises the following steps:

(1) dewatering the dyed fabric by a squeezing scutcher;

(2) drying the dehydrated fabric through a shaping machine; wherein the slurry tank of the first shaping machine is internally provided with a penetrant;

(3) shaping the dried fabric in the step (2) by a second shaping machine to obtain a final finished fabric;

wherein, a sizing agent is matched in a size groove of the second sizing machine; the auxiliary comprises 2-3% of optimally mixed 5788, 1-2% of Kefeng 388D, 2-3% of transfer 635T and the balance of water according to mass fraction.

The process is obtained by comprehensively considering the cost and the finished product effect based on the actual production of the fabric after-finishing process in the prior art, firstly, in the step (1), the dyed fabric has higher water content, is scutched and dehydrated by a mangle scutcher, if not dehydrated, the dehydration cost of a later-stage setting machine is improved, and on the other hand, the fabric has high water content, a penetrating agent and a setting auxiliary agent cannot effectively enter the fabric, the setting effect is poor, and the obtained finished product has poorer draping feeling; secondly, drying the fabric by using a first sizing machine and a penetrating agent, wherein the penetrating agent can uniformly penetrate into the fiber for the later finished product sizing cationic additive to obtain the required hand feeling and play a role in reducing the dosage of the additive;

finally, based on that most of dyes and the like adopted in the dyeing process are anionic, if a strong cationic auxiliary agent is adopted in the setting process, the strong cationic auxiliary agent can react with the dyes and the curing agent auxiliary agent in the dyeing process to cause stiff and smooth fabrics and poor hand feeling, so that the inventor selects and mixes a plurality of weak cationic or nonionic setting auxiliary agents through tests, and the good mixture 5788 has the effects of making the fabrics hydrophilic and absorbing moisture and releasing sweat; kefeng 388D has the function of enabling the fabric to have cool hand feeling; the biography 635T has the functions of enabling the fabric to have stiff, smooth, thick and resilient handfeel, the three auxiliaries are weak-cation and nonionic auxiliaries, are stable after being mixed and weak in ionicity, do not react with a color fixing agent possibly in a dye vat on the surface of a yarn-dyed fabric, enable the obtained finished fabric to have few flaws and good handfeel under the synergistic effect, and meanwhile, are low in addition, and solve the problem of flaws such as silicone oil stains and the like caused by large consumption of the auxiliaries in the prior art.

Preferably, in the step (1), the pressure of the press roll of the water squeezing scutching machine is 2-4kg, the dewatering amount of the fabric is just proper under the pressure, and the penetration of the post-stage penetrating agent and the setting auxiliary agent is better.

The penetrating agent is a non-ionic penetrating agent, and the concentration is 1-2 g/L. The penetrating agent added in the drying process is nonionic, so that the subsequent finished product sizing cationic auxiliary agent can uniformly penetrate into the fibers, the required hand feeling is obtained, the effect of reducing the dosage of the auxiliary agent is achieved, and the auxiliary agent cannot react with the subsequent auxiliary agent. The penetrant is a Henscman 1120 penetrant.

The forming auxiliary agent is prepared in advance by a material melting barrel, heated to 40-60 ℃, and then added into a slurry tank of a second forming machine. The prepared auxiliary agents are prepared in advance, so that the three auxiliary agents can be fully and uniformly mixed, and the mixture is usually mixed for more than 15 min.

In the application, the fabric is shaped by the shaping machine twice, the water content of the fabric is increased after the fabric is permeated by the penetrating agent in the first shaping machine, if the permeability of the fabric is directly poor by the aid of the second shaping machine, the fabric is conveniently permeated into the shaping aid in the second shaping machine after being dried, the drying oven temperature of the first shaping machine is 165-180 ℃, and the speed of the fabric passing through the first shaping machine is 25-30 m/min. At relatively fast vehicle speeds, the oven temperature is high, quickly removing a large amount of moisture from the fabric.

In the second setting machine, the speed of the fabric passing through the second setting machine should be slow, so that the setting auxiliary agent can fully modify the fabric, the speed is 20-25m/min optimal, and the temperature of the oven is 160-175 ℃. The color change of temperature to sensitivity is large, preferably, the light color series fabrics are preferably 160 ℃, the fabric can shrink uniformly when running in a machine box at the speed of about 20 meters, otherwise, the fabric surface is uneven and loses the drape.
