Description
Technical Field
The embodiment of the invention relates to the technical field of fiber materials, and particularly relates to a production process of an acetic acid-like cloth.
Background
Cellulose acetate, which is a cellulose acetate, is a thermoplastic resin obtained by esterifying acetic acid as a solvent and acetic anhydride as an acetylating agent under the action of a catalyst, and is a chemically modified natural high polymer obtained by esterifying hydroxyl groups in cellulose molecules with acetic acid, and the performance of the polymer depends on the degree of acetylation. The acetate fibers can selectively adsorb and remove certain low-content organic matters; easy to wet, has good liquid permeability and excellent adsorbability; soft, smooth and elastic in hand feeling; the air permeability is good, the drying is fast, and no static adsorption exists; has good weaving performance and luster and hand feeling of natural mulberry silk, so the natural mulberry silk is commonly used for fabrics to improve the luster and the quality of the fabrics.
The main base cloth used in the fields of electronic adhesive tape, medical cloth and trademark cloth is acetate cloth made of acetate fiber. The purpose that hands can tear in the warp and weft directions can be achieved by making the base cloth from the acetate fibers, so that corresponding products are manufactured by gluing and cutting, and the production speed in the electronic industry, the trademark industry and the medical field can be increased.
However, the conventional acetate cloth is generally expensive because the raw material is acetate fiber. Other types of easy-to-tear cloth on the market, such as polyester cationic fibers (cationic modified polyester), need to be colored by cationic dyes at normal temperature. With the stricter environmental protection requirements, the dye is generally required to meet the RoHS standard of the European Union. The dye meeting the RoHS standard of the European Union is a high-temperature disperse dye and needs high-temperature coloring. Therefore, the dye which is used for the prior terylene cationic fiber and accords with the European Union RoHS standard has poor color fastness, and is easy to have side-to-side color difference and head-to-tail color difference. In addition, the grey cloth of the polyester cationic fiber is alternately treated by acid and alkali in the refining and dyeing processes, and then the easy-to-tear cloth is obtained through soaping and shaping, so that the working procedures are complex, and the safety of the operation process is difficult to guarantee.
Disclosure of Invention
Therefore, the embodiment of the invention provides a production process of an imitated acetic acid cloth, which aims to solve the problem that the existing easy-tearing cloth is high in cost; coloring is difficult, color fastness is poor, and color difference and cylinder difference are easy to occur; the process is complex, the safety of the operation process is difficult to ensure, and the like.
In order to achieve the above object, the embodiments of the present invention provide the following technical solutions:
according to the first aspect of the embodiment of the invention, the embodiment of the invention provides a production process of an imitated acetic acid cloth, wherein color ink particles are added during spinning to obtain color silk fibers, then a gray cloth is manufactured, the fibers are aged by decrement, and then soaping and sizing are carried out to obtain the imitated acetic acid cloth.
Further, the preparation method of the color silk fiber comprises the following steps: the polyester fiber is sequentially dried, extruded in solution, drawn and cooled, and then added with titanium dioxide and color ink particles for spinning.
The color ink particles are also called as color masterbatch or color seed, and are a special colorant for high polymer materials, also called as Pigment Preparation (Pigment Preparation). The color master is mainly used for plastics. Color concentrates are composed of three basic elements, Pigment or dye, carrier and additive, and are aggregates prepared by uniformly supporting an excessive amount of Pigment in a resin, which can be referred to as Pigment concentrates (Pigment concentrates), so that they have a higher tinctorial strength than the Pigment itself. Has the advantages of accurate color, high color fastness, reduced dye cost, shortened production time, and the like.
In the spinning process, the strength of the fibers can be reduced by adding titanium dioxide.
Further, the polyester fiber includes a regenerated fiber (e.g., a recycled regenerated fiber such as a cola bottle) and an ECDP-dyeable fiber.
Further, the weight reduction is carried out by using a continuous weight reducing machine.
Further, the decrementing comprises: adding decrement liquid into the cylinder, heating to 90 ℃ at the speed of 0.9 ℃/min, keeping the temperature for 10 minutes, heating to 110 ℃ at the speed of 0.9 ℃/min, keeping the temperature for 10 minutes, heating to 140 ℃ at the speed of 0.9 ℃/min, keeping the tension at 3.0-6.0 kg, and keeping the temperature for 6 hours at the speed of 80 m/min.
Further, the weight reducing liquid comprises the following components in parts by weight: 500 parts of water, 40 parts of liquid alkali, 10 parts of soda ash, 2 parts of a refining agent, 1 part of an oil removing agent and 5-10 parts of an alkali decrement accelerant.
Further, the setting temperature is 180 ℃.
According to a second aspect of embodiments of the present invention, there is provided a simulated acetic acid cloth made by any of the processes described above.
The embodiment of the invention has the following advantages:
1. the invention adds color ink granules to prepare colored fiber during spinning, increases the temperature by 10-20 ℃ on the basis of normal coloring temperature, and adds decrement liquid containing liquid caustic soda, soda ash, refining agent, degreasing agent and alkali decrement accelerant, wherein the alkali decrement accelerant enables the liquid caustic soda and the soda ash to react with the fiber more quickly and better, and the fiber is embrittled to achieve the effect of hand tearing. The acetic acid-like cloth prepared by the invention has the advantages of quick coloring, accurate color, high color fastness, difficult fading, low production cost and the like, thereby enhancing the functional stability of the product.
2. The production process has low requirement on the strength of the raw materials, is not limited to low-strength fibers, can embrittle any polyester fiber (different raw materials only need to adjust the temperature and the concentration of an auxiliary agent), reduces the pollution of dyeing processes and dyes to the environment, shortens the dyeing time, improves the production efficiency and reduces the production cost.
3. The invention only needs the commonly used auxiliary agents such as liquid caustic soda, soda ash, alkali decrement accelerant and the like instead of acid-base alternation, so that the safety of workers in the operation process is improved. The prepared acetic acid-imitated cloth has stable strength, has no difference with the acetic acid cloth, can replace the acetic acid cloth in the industries of electronic adhesive tapes, medical cloth and trademark cloth, and has higher competitiveness than the products in the prior art.
