Description
Technical Field
The invention relates to the technical field of cool fabrics, in particular to a continuous cool fabric and a manufacturing method thereof.
Background
With the continuous improvement of living standard, people have higher and higher requirements on the functionality and the comfort of the clothes. The fabric is hot in weather, a body is very easy to sweat, most of sweat is removed through evaporation, wiping and underwear adsorption, so that the fabric is very necessary for moisture absorption and sweat removal, and the cool fiber is also used as required.
The cool fiber is a new term of textile materials at present, and means a fiber which can prevent discomfort when wet and is excellent in cool touch. The principle is that a medium with low heat absorption speed and high heat dissipation speed in nature is added into carriers such as terylene, chinlon, regenerated cellulose fiber and the like, and the woven fabric has excellent cool feeling at the moment of contacting with the skin. At present, the novel cool fiber like Softcool has started to be applied to sports and leisure clothes, and is also concerned in the field of home textile.
For example, CN103614796A discloses a method for producing cool honeycomb fiber, which comprises adding high thermal conductivity nano silicon carbide powder into mother particles or pulp of honeycomb fiber according to a weight ratio of 1-2%, stirring uniformly, and flashing to form filaments to obtain honeycomb fiber. The invention relates to a technical method for improving the cooling effect of honeycomb fibers by changing the heat-conducting property of thermal-resistance reinforced fibers of the honeycomb fibers by using silicon carbide and the like, and high-heat-conduction nano silicon carbide powder is added into the honeycomb fibers according to the proportion of about 1-2 percent, so that the heat conductivity of the fibers can be improved to 2.0-3.8 from the original 0.1, and the heat conductivity is improved by 20-40 times. This document also mentions that one key point is: the cooling sensation depends on the combined action of thermal resistance and moisture resistance. Therefore, in the case of the same fiber fineness, the fiber filled with the heat conductive material has better heat dissipation than that of the fiber not filled with the heat conductive material, but the filler formed in the fiber body hinders the water transport of the fiber, thereby reducing the diffusion of water into the fiber and reducing the moisture conductivity of the fiber. Therefore, the cool fiber exhibits an inverse ratio of thermal conductivity and moisture conductivity depending on the proportion of the filler, i.e., the better the thermal conductivity, the worse the moisture conductivity.
Disclosure of Invention
In order to overcome the defects and shortcomings in the prior art, the invention aims to provide the continuous cool feeling fabric with moisture conductivity and heat conductivity and the manufacturing method thereof.
The purpose of the invention is realized by the following technical scheme:
the continuous cool fabric comprises a fabric base layer woven by cool terylene and a water-based polyurethane coating coated on the surface of the fabric base layer, wherein the cool terylene comprises the following raw materials in parts by weight:
the cool polyester fiber doped with the mica powder is adopted in the invention, and has the characteristics of firmness, durability, good elasticity, difficult deformation, corrosion resistance, insulation, stiffness, smoothness and the like, and the moisture conductivity of the cool polyester fiber is relatively less influenced by the mica powder due to the low moisture absorption performance of the cool polyester fiber. The invention solves the problem of poor moisture conductivity of the polyester fiber, does not pay attention to the property of the fiber, but pay attention to the structure of the fabric. The moisture conductivity of the fabric is influenced by the moisture absorption of single fibers and the moisture transmission efficiency among the fibers, and the problem is not noticed yet. According to the invention, the surface of the fabric is coated with the water-based polyurethane coating, so that the water-based polyurethane can enable single polyester fibers to form efficient physical connection, and moisture can be diffused through the polyurethane coating, thereby improving the moisture diffusion efficiency among the fibers.
The coating treatment of the waterborne polyurethane coating is different from the hydrophilic finishing of common polyester fibers, the polyester has poor hygroscopicity but not poor moisture conductivity, the hydrophilic finishing of the polyester refers to that the hydrophilic finishing agent is bonded with the surface of the polyester so that the surface has hydrophilic groups, the dyne value of the surface of the polyester is changed so that the polyester is easily soaked by water, and then the polyester is diffused and evaporated in the polyester, so that the moisture absorption and removal performance is improved. The waterborne polyurethane coating of the invention also has the effect of polyester surface modification, and can improve the moisture absorption rate of polyester fibers by the same mechanism, but the improvement degree is not as good as that of the common organosilicon hydrophilic finishing agent from the aspect of the mechanism. The more important function of the waterborne polyurethane coating is to form physical bridges among single fibers, so that moisture can span among the single fibers through the polyurethane coating, thereby greatly improving the moisture diffusion efficiency, namely the moisture conductivity.
Wherein the mica powder has a sheet diameter of 8-12 μm and a sheet thickness of 0.5-1.5 μm.
Wherein the antioxidant consists of an antioxidant 1010 and an antioxidant 168 according to the weight ratio of 1: 1.
Wherein the ultraviolet absorbent is one or more of salicylate absorbent, benzotriazole absorbent and hindered amine absorbent.
Wherein, the lubricant is one or more of zinc stearate, calcium stearate and talcum powder.
The preparation method of the cool polyester comprises the following steps: mixing the raw materials for forming the cool polyester, feeding the mixture into a screw extruder for melting, then spraying the mixture through spinneret orifices on a spinneret plate, cooling the mixture by air, and then performing an elasticizing process to obtain the cool polyester.

(2) adding 40-60 parts by weight of organic solvent and 10-20 parts by weight of hydrophilic chain extender into the polyurethane prepolymer, reacting at the temperature of 50-60 ℃ for 2-3h, and then adding 100 parts by weight of water and 1-2 parts by weight of silane coupling agent to prepare the waterborne polyurethane coating;
(3) weaving the cool terylene into a fabric base layer, soaking the fabric base layer into the waterborne polyurethane coating according to the bath ratio of 1:10-12 for 30-60min, taking out the cool terylene, and drying in an oven at 60-80 ℃ to obtain the continuous cool fabric.
The properties of the aqueous polyurethane coating are varied, and not all aqueous polyurethane coatings can meet the requirements of the present invention. Therefore, the invention provides a waterborne polyurethane coating and a method for coating the waterborne polyurethane coating on a fabric base layer, namely a manufacturing method of a continuous cool fabric. The water-based polyurethane coating prepared by the method can improve the hydrophilicity of the fiber surface, fill the gaps among the fibers and effectively improve the moisture transmission efficiency among the fibers, thereby obviously improving the moisture absorption of the polyester fibers and solving the problem of poor moisture absorption of cool polyester.
Wherein the organic tin catalyst is dibutyltin dilaurate.

The invention has the beneficial effects that: the cool polyester fiber doped with the mica powder is adopted in the invention, and has the characteristics of firmness, durability, good elasticity, difficult deformation, corrosion resistance, insulation, stiffness, smoothness and the like, and the moisture conductivity of the cool polyester fiber is relatively less influenced by the mica powder due to the low moisture absorption performance of the cool polyester fiber. The invention solves the problem of poor moisture conductivity of the polyester fiber, does not pay attention to the property of the fiber, but pay attention to the structure of the fabric. The moisture conductivity of the fabric is influenced by the moisture absorption of single fibers and the moisture transmission efficiency among the fibers, and the problem is not noticed yet. According to the invention, the surface of the fabric is coated with the water-based polyurethane coating, so that the water-based polyurethane can enable single polyester fibers to form efficient physical connection, and moisture can be diffused through the polyurethane coating, thereby improving the moisture diffusion efficiency among the fibers.

The difference from example 1 is that:
the cool polyester fiber is conventionally finished by an organic silicon hydrophilic finishing agent, and then is woven into a fabric base layer without polyurethane coating treatment.

The difference from example 1 is that:
and (3) soaking the cool polyester fibers in the waterborne polyurethane coating by the same method, drying, and weaving into the fabric.
Comparative example 4
The difference from example 1 is that:
the fabric base layer is finished by the organic silicon hydrophilic finishing agent without polyurethane coating treatment.
The test of thermal and wet resistance was carried out according to ISO11092:2004 on the fabrics of example 1 and of comparative examples 1 to 3, with the following results:
| thermal resistance (10)-3k*m2*W-1) | Wet resistance (Pa x m)2*W-1) | |
| Example 1 | 9.883 | 4.416 |
| Comparative example 1 | 9.117 | 5.557 |
| Comparative example 2 | 9.682 | 5.358 |
