Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The invention provides a finishing method of polyester fabric for hotel linen, which comprises the following specific implementation modes:

step 1, preparing a sizing agent;

step 1.1, weighing the following raw materials in percentage by mass: 2-4% of paste, 5-15% of alkaline agent, 0.5-1.5% of non-ionic penetrating agent and the balance of water, wherein the sum of the mass percentages of the components is 100%;

in step 1.1, the paste is any one of polysaccharide compounds with polyol groups or carboxyl groups; the alkaline agent is inorganic alkali, basic salt or an alkaline compound containing amino; the non-ionic penetrant is any one of polyoxyethylene ether (such as op series), polyvinyl alcohol (alcoholysis degree is not more than 88) and polyethylene glycol (molecular weight is not more than 600);

the polysaccharide compound with polyol group or carboxyl is any one of modified starch, guar gum, sodium alginate, modified tapioca starch and modified konjac starch;

the inorganic alkali is sodium hydroxide, and the basic salt is sodium silicate or sodium carbonate; the basic compound containing amino is ethylenediamine or triethylamine.

The polyoxyethylene ether is any one of op-9, op-10 and op-15, the polyvinyl alcohol is polyvinyl alcohol 1788, and the polyethylene glycol is polyethylene glycol 600.

Step 1.2, mixing the raw materials weighed in the step 1.1 to obtain a sizing agent, wherein the pH value of the sizing agent is 10.5-11;

step 2, adopting the sizing agent prepared in the step 1 to perform sizing treatment on the polyester fabric:

applying the sizing agent prepared in the step 1 to a sizing machine by adopting a padding method to size the polyester fabric, so that the sizing rate is 70-80%; after sizing, sequentially carrying out primary drying, steaming, primary washing, secondary washing and secondary drying;

the formula for calculating the sizing rate is as follows:

wherein the temperature of primary drying is 70-90 ℃, and the time of primary drying is 3-5 min; steaming at the temperature of 110-130 ℃ for 10-20 min; the primary washing temperature is 50-60 ℃, the washing time is 3-5 min, the secondary washing temperature is normal temperature, and the washing time is 1-3 min; the temperature of the secondary drying is 90-100 ℃, and the time of the secondary drying is 3-5 min.

Step 3, performing restrictive shearing treatment on the polyester fabric treated in the step 2;

wherein, the specific parameter requirements of the restrictive shearing treatment are as follows: the cutting frequency is 25-45 times/min, and the shearing strength controls the reduction rate of the fabric strength to be 5-15%.

The polyester fabric with ester group is sized by sizing agent to make the surface of the polyester fabric be uniformly coated, and the treatment temperature and time are controlled to make the fiber be bulked, the surface of the polyester fabric have dents and the strong damage is less. The detection results of the polyester fabric fibers before and after the sizing agent treatment are shown in table 1, the surface appearance of the fabric is shown in figures 1 and 2, and the cross section of the fabric is shown in figures 3 and 4.

TABLE 1 physical Properties of polyester Fabric fibers before and after sizing agent treatment

The treated polyester fabric has reduced elastic modulus as shown in table 1, which indicates that the fabric has enhanced flexibility and reduced rigidity; and the strength loss of the fabric is only 3 percent, the damage to the fabric is negligible, and the moisture absorption rate is increased.

As shown in fig. 1, the fiber surface was smooth and without dents before the fabric was sized; as shown in fig. 2, the fiber surface was dented to some extent after sizing, indicating that the moisture of the fabric could be drained through the dented portions after moisture absorption. The main reason is that the elastic modulus of macromolecular chains is reduced, but the strength reduction rate of the fabric is changed by only 3 percent; at this time, ester groups are hydrolyzed to a certain extent, so that the thickness of the skin wall of the fiber is thinned, and the softness of the fiber is increased; and the alkali swells the fiber, so that the pore diameter of the fiber is increased, and the moisture absorption of the fiber is increased.

As shown in figure 3, the fiber section aperture skin layer is thicker and the aperture is smaller before the fabric is sized; as shown in fig. 4, the pore diameter skin layer of the cross section of the sized fiber becomes thinner and the pore diameter becomes larger, which shows that the sized fiber is swelled, the pore diameter of the fabric can hold more moisture, and the moisture absorption is increased.

The function of each component in the sizing agent is as follows: the alkaline agent is used for hydrolyzing the hydroxyl of the polyester fabric, the paste is used for controlling the hydrolysis degree, and the nonionic penetrating agent is used for increasing the penetration and the solubilization.

Shearing polyester fabric, selecting a grinding roller device with a cylindrical cutter, enabling the grinding roller to perform transverse transmission when rotating, cutting the fabric, and controlling a certain frequency (controlled at 25-45 times/min) to enable the fabric to be capable of limiting shearing, wherein the shearing strength controls the fabric strength reduction rate to be 5-15%, the service value is kept, and the result is shown in table 2.

TABLE 2 restrictive shear front and back fabric strength control

As can be seen from the table 2, the strength of the polyester fabric is reduced by controlling the shear strength, the reduction range is 6.19% in the warp direction, 10% in the weft direction, the elongation at break is 8% in the warp direction and 3.5% in the weft direction, the strength reduction and the elongation at break are both within the range of the requirement of the enterprise strength standard (the strength reduction is 15%), and the wearability of the fabric is not affected.

The polyester fabric treated by the sizing agent generates certain fluff, and the chemical sizing agent is subjected to restrictive shearing, so that the polyester fabric treated by the chemical sizing agent is kept in strength (the reduction rate is controlled within the range of 5-15%), a three-dimensional conformation is formed, the water holding capacity is greatly increased due to the suede formed on the surface of the fabric, and a triple moisture absorption effect is obtained, which is illustrated in table 3 and fig. 5.

TABLE 3 variation of physical Properties of polyester fabrics treated with different treatments

The simulation effect of fig. 5 and table 3 show that the grinding roller performs transverse transmission when rotating, the material generates a certain amount of fluff after being treated at a certain frequency, and the chemical pulp is subjected to restrictive shearing, so that the strength of the treated polyester fabric is kept (the reduction rate is controlled to be 5-15%), a three-dimensional conformation is formed, the water holding capacity is greatly increased, and a triple moisture absorption effect is obtained.
