Description

Technical Field

[0001] The present application relates to the field of textile technology, and in particular to a double-sided jacquard blanket and a preparation process thereof. Background Art

[0002] As a decorative and practical textile, jacquard blankets are widely used in home decoration, hotels and other places. However, traditional jacquard blankets can usually only display a single pattern, and the feel and durability need to be improved. With the improvement of consumers' aesthetic needs, higher requirements are placed on the beauty and practicality of jacquard blankets, and some double-sided jacquard blankets are gradually emerging.

[0003] At present, there are some double-sided textiles on the market, made of chemical fibers and cotton fibers, with exquisite patterns, but the surface often lacks velvet and is less gentle. This type of product is not only thick, but also has lower color and texture. Summary of the invention

[0004] In order to improve the texture of the existing double-sided jacquard blanket, the present application provides a double-sided jacquard blanket and a preparation process thereof.

[0005] In a first aspect, the present application provides a preparation process of a double-sided jacquard blanket, which adopts the following technical solution: A preparation process of a double-sided jacquard blanket comprises the following specific steps: S1: Double-sided pattern design, determine the patterns on the front and back of the blanket; S2: double-sided weaving of the colored yarn to obtain a woven blanket product, treating the blanket product with a biological enzyme at 40-60° C., and then impregnating and finishing with an alkali solution; S3: trimming, washing, drying and shaping the treated blanket, performing mercerization after shaping, and then performing secondary shaping and pre-shrinking treatment to obtain a double-sided jacquard blanket; The biological enzyme comprises the following raw materials in parts by weight: 20-30 parts of pectinase, 10-25 parts of hemicellulase, 10-15 parts of amylase, and 1-3 parts of permeabilizing agent.

[0006] By adopting the above technical solution, the three-dimensional sense and layering sense of the blanket can be enhanced through double-sided weaving technology. Biological enzyme treatment after double-sided weaving can decompose impurities such as pectin in the double-sided woven blanket, make the surface of the blanket fiber smoother, and enable other subsequent treatment liquids to directly contact the blanket surface, thereby improving the efficiency and effect of subsequent treatment. The blanket is then treated with alkaline solution to further remove impurities in the initial blanket product, promote the expansion of the blanket fibers, improve the bonding force between the blanket fibers, enhance the strength and stability of the blanket, and reduce the phenomenon of blanket fiber breakage during subsequent processing and use.

[0007] The blankets treated with bio-enzyme and alkali are trimmed to remove burrs and uneven parts on the surface of the blankets, and the impurities adhering to the fiber surface during the bio-enzyme treatment and alkali solution immersion are cleaned and removed. The blankets are then dried to initially fix their shape and maintain their dimensional stability.

[0008] Mercerizing the initially shaped blanket can improve its gloss and softness, make it smoother and improve its texture. Secondary shaping can further fix the shape of the blanket, and pre-shrinking can reduce the shrinkage of the blanket during use and improve its dimensional stability.

[0009] Preferably, the mercerization treatment adopts a cylindrical or flat-width mercerization machine, and alkali liquid mercerization is used in the mercerization treatment, the treatment temperature is 15-25° C., and the concentration of the alkali liquid is 210-250 g / L.

[0010] By adopting the above technical solution, the alkali solution can open the scale layer on the surface of the blanket fiber to form a smooth surface, improve the glossiness of the blanket, reduce the friction between the fibers, and improve the feel of the blanket. In the mercerization process, the alkali solution reacts with the fiber surface, which can make the fiber structure more stable and reduce the deformation of the fiber during washing and use.

[0011] Preferably, the pre-shrinking treatment uses steam pre-shrinking at a speed of 15-30m / min.

[0012] By adopting the above technical solution, steam pre-shrinking the blanket can make the blanket fiber expand under the action of high-temperature steam, causing a certain stress to be generated inside the blanket fiber. When the stress is released, the fiber will return to a relatively stable state, thereby improving the dimensional stability of the blanket and reducing the shrinkage rate of the blanket. The pre-shrinking treatment of the double-sided jacquard blanket by steaming can promote uniform treatment of both sides of the double-sided jacquard blanket and reduce the dimensional stability and texture differences caused by uneven treatment.

[0013] Preferably, the secondary shaping uses a fluffy treatment liquid and a wrinkle-free resin finishing liquid to treat the blanket in sequence, and the fluffy treatment liquid includes the following raw materials in parts by weight: 40-60 parts of a fluffy softener, 10-15 parts of a hydrophilic fluffy silicone oil, 10-20 parts of a crosslinking agent, and 5-8 parts of glacial acetic acid.

[0014] By adopting the above technical solution, the fluffy softener can penetrate into the fibers of the blanket, improve the fluffiness and flexibility of the blanket, improve the moisture absorption and air permeability of the blanket, and improve the texture and comfort of the blanket. The use of hydrophilic fluffy silicone oil can form a hydrophilic film on the surface of the blanket, improve the moisture absorption and air permeability of the blanket, and improve the fluffiness and softness of the blanket. Adding an appropriate amount of glacial acetic acid can neutralize the alkaline substances produced in the treatment solution, reduce the discoloration and damage of the blanket during the subsequent treatment process, and improve the texture and comfort of the blanket.

[0015] Preferably, the secondary setting temperature is 130-160°C.

[0016] Preferably, the hydrophilic fluffy silicone oil comprises the following raw materials in parts by weight: 30-40 parts of terminal epoxy silicone oil, 10-20 parts of terminal amino polyether, 3-5 parts of quaternary ammonium cationic surfactant, and 60-80 parts of solvent.

[0017] By adopting the above technical solution, the polysiloxane and polyether in the silicone oil can be repeatedly alternated and arranged in a directional manner on the surface of the blanket fiber, and the amino group can play an anchoring role, so that the hydrophilic and fluffy silicone oil can be firmly attached to the surface of the blanket fiber, thereby improving the softness and washability of the blanket. At the same time, the quaternary ammonium cationic surfactant is used to improve the hydrophilicity of the silicone oil, enhance the polarity and ionicity of the silicone oil, and form hydrogen bonds with the aqueous solution, which require greater energy to be broken, so that the silicone oil can be better adsorbed and bonded to the surface of the fiber, and the prepared hydrophilic and fluffy silicone oil can improve the fluffy feel, softness and washability of the blanket.

[0018] Preferably, the method for preparing the hydrophilic fluffy silicone oil comprises the following specific steps: The solvent is mixed with the epoxy-terminated silicone oil and the amino-terminated polyether, and the temperature is raised to 80-85°C for reaction to obtain modified silicone oil. The modified silicone oil is then mixed with a quaternary ammonium cationic surfactant to obtain a hydrophilic fluffy silicone oil after reaction.

[0019] Preferably, the permanent-ironing resin finishing liquid comprises polyurethane resin, silicone resin and a cross-linking agent, and the mass ratio of the polyurethane resin, silicone resin and cross-linking agent is (30-40): (10-20):2.

[0020] By adopting the above technical solution, the active groups of the polyurethane resin can react with the blanket fibers, which has a certain non-ironing effect, and at the same time, there is no strength loss to the blanket. Aluminum citrate can play a buffering role in the reaction between the polyurethane resin and the fiber, thereby improving the strong retention effect of the blanket. Silicone resin has good film-forming properties, wear resistance and strong protective effects, and can be compounded with polyurethane resin to improve the strength retention rate of the fiber. At the same time, silicone resin can also play a softening role, improving the flatness and texture of the blanket.

[0021] In a second aspect, the present application provides a double-sided jacquard blanket, which adopts the following technical solution: A double-sided jacquard blanket is prepared by the above preparation process.

[0022] In summary, this application has the following beneficial effects: 1. Since the present application adopts the method of biological enzyme treatment after double-sided weaving, it can decompose the impurities such as pectin in the double-sided woven blanket, and the blanket is treated with alkali solution to further remove the impurities in the blanket and enhance the strength and stability of the blanket. Mercerizing and pre-shrinking the blanket that has been preliminarily shaped can improve the gloss and softness of the blanket, make the blanket smoother, improve the texture and dimensional stability of the blanket, and reduce the shrinkage of the blanket during use.

[0023] 2. In this application, a fluffy softener and a hydrophilic fluffy silicone oil are used to improve the fluffiness and softness of the blanket. The hydrophilic fluffy silicone oil made of terminal epoxy silicone oil, terminal amino polyether and quaternized cationic surfactant can form hydrogen bonds with the aqueous solution, so that the silicone oil can be better adsorbed and bonded to the surface of the fiber, thereby improving the fluffy feel, softness and washability of the blanket.
