Description

Technical Field

[0001] The invention relates to a pleated curtain fabric, in particular to a high-temperature resistant and high-resilience pearlescent pleated curtain fabric and a manufacturing method thereof. Background Art

[0002] Pearlescent pleated curtain fabric is a pleated curtain fabric with pearlescent effect. This fabric is made by applying pearlescent powder (such as artificial mica) to the surface of the base fabric, so that it presents a pearlescent glittering effect under light, and combined with the pleated design, it increases the three-dimensional sense and beauty of the fabric.

[0003] Pearlescent pleated curtain fabric is suitable for various indoor scenes, such as living room, bedroom, office, etc., especially for environments that require sunshade and heat insulation. It not only has a good decorative effect, but also has practical functionality.

[0004] However, in modern building environments, especially in summer or tropical areas, ordinary pearlescent pleated curtain fabrics will quickly deform under high temperatures and strong direct sunlight, and then lose their original elasticity and durability, seriously affecting their appearance and practicality. This problem is particularly prominent in high-frequency use scenarios such as offices and public places.

[0005] Therefore, the research and development and production of high-temperature resistant and high-rebound pearlescent pleated curtain fabrics will be an important measure to solve the current market pain points and meet future development trends. Summary of the invention

[0006] Based on the technical problems existing in the above-mentioned prior art, the main purpose of the present invention is to propose a high-temperature resistant and high-resilient pearlescent pleated curtain fabric and a manufacturing method thereof, which can still maintain good resilience in a high temperature environment of 60°C, extend the service life of the curtain, and maintain its shape and beauty even under frequent use.

[0007] The technical solution adopted by the present invention to solve its technical problem is:

[0008] A method for manufacturing a high-temperature resistant and high-resilience pearlescent pleated curtain fabric comprises the following steps:

[0009] S1. Base fabric material selection and organizational structure design

[0010] The warp and weft yarns of the base fabric are made of medium and low F-number DTY polyester filaments to ensure the fabric's crispness and elastic recovery performance; the base fabric is woven with 2 / 2 square weave;

[0011] S2. Pearlescent coating finishing of base fabric

[0012] Apply pearlescent slurry on the reverse side of the base fabric;

[0013] S3. High temperature wrinkle treatment of base fabric

[0014] A mechanical arm is used to apply 0.2-0.3MPa pressure on the surface of the base fabric with irregular cyclic mechanical movement, and then irregular wrinkles are initially formed through the steam pipe, and then the irregular wrinkles are fixed through high temperature setting at 190-220℃ to form a strong three-dimensional wrinkle effect;

[0015] S4. Rebound treatment of base fabric

[0016] The elastic agent emulsion is evenly coated on the base fabric, and then dried and cured in an oven at 150-170°C for 35-45s, so that the base fabric can still have good elasticity and maintain a good shape in a high temperature environment or after high temperature exposure;

[0017] The resilience agent emulsion is prepared by mixing and stirring 35-40 parts of acrylic emulsion, 0.5-1 part of cross-linking agent, and 60-65 parts of deionized water;

[0018] S5. Pleated treatment of base fabric

[0019] The base fabric after the rebound treatment is heat-set at a temperature of 95-105°C and a pressure of 0.45-0.55MPa. This heat setting can form permanent wrinkles on the fabric under high temperature conditions, making the curtains appear pleated, thereby obtaining high-temperature resistant and high-rebound pearlescent pleated curtain fabric.

[0020] According to a further preferred technical solution, the pearlescent slurry is prepared by mixing, by weight, 1 to 2 parts of nano-pearlescent powder, 30 to 35 parts of acrylic emulsion, 0.5 to 1 part of adhesive, 10 to 15 parts of ultraviolet light absorber, and 40 to 55 parts of deionized water.

[0021] According to a further preferred technical solution, during the high-temperature crumpling treatment of the base fabric, the vibration frequency of the robot arm is 100 to 120 times per minute.

[0022] A high-temperature-resistant and high-rebound pearlescent pleated curtain fabric is made by adopting the above method.

[0023] The beneficial effects of the present invention are:

[0024] (1) Excellent high temperature resistance and resilience: The fabric uses low F-number DTY polyester filament as the base fabric material and is treated with a suitable coating ratio, so that it can still maintain good resilience in a high temperature environment of 60°C, extending the service life of the curtain and maintaining its shape and beauty even under frequent use.

[0025] (2) High efficiency heat insulation and energy saving: The pearlescent layer and ultraviolet light absorber on the surface of the fabric can effectively reflect light and block ultraviolet rays. Through the combination of the pearlescent layer and the ultraviolet light absorber, 80% of light reflection and 20% of ultraviolet light absorption can be achieved, which prolongs the aging and discoloration of the curtains themselves, effectively reduces indoor heat accumulation, and reduces air conditioning energy consumption, meeting the requirements of modern energy conservation and environmental protection.

[0026] (3) Anti-ultraviolet function: The application of nano-level pearlescent powder and ultraviolet light absorber can block 99.5% of the ultraviolet rays from harming the indoor environment, protecting people's health and indoor furniture, floors, etc. from damage by ultraviolet rays.

[0027] (4) Beautiful decorative effect: The fabric adopts irregular wrinkling technology and pleated design, which increases the three-dimensional sense and decorative effect of the curtains. The pearlescent texture makes it more beautiful, meeting the needs of modern architecture for both beauty and practicality.

[0028] (5) Strong processability and stability: Using polyester fiber filament as raw material, combined with the warp and weft interwoven woven fabric solution, ensures the stability, plasticity and processability of the curtain fabric, which is suitable for large-scale production and application.

[0029] (6) Comprehensive multifunctionality: The fabric combines high temperature resistance and rebound, heat insulation, UV protection, and decoration, which solves the multiple demands for curtain fabrics in modern architectural environments. It is a new type of curtain fabric with excellent comprehensive performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 It is a manufacturing flow chart of high temperature resistant and high resilience pearlescent pleated curtain fabric.

[0031] Figure 2 It is the organizational structure diagram of the base fabric in the present invention. DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, the specific implementation process of the present invention is as follows:

[0034] (I) Base fabric material selection and organizational structure design

[0035] a. The warp and weft yarns of the base fabric are made of medium and low F-number DTY polyester filaments to ensure the crispness and elastic recovery performance of the fabric;

[0036] Polyester filaments with medium and low F numbers have moderate rigidity and elasticity, which enables the fabric to maintain good resilience when subjected to high temperatures or external forces. The structure of this material makes it difficult for the fabric to lose its deformation memory after being subjected to high temperatures, thereby maintaining its elasticity.

[0037] b. The base fabric is woven with 2 / 2 square weave, such as Figure 2 As shown in the figure; the stable square weave structure is adopted to ensure that the pearlescent powder can be evenly coated on the surface of the base fabric;

[0038] (II) Pearlescent coating finishing of base fabric

[0039] Apply pearlescent slurry on the reverse side of the base fabric; the pearlescent slurry is prepared by mixing 1-2 parts of nano-pearlescent powder, 30-35 parts of acrylic emulsion, 0.5-1 part of adhesive, 10-15 parts of ultraviolet light absorber, and 40-55 parts of deionized water by weight;

[0040] The pearlescent slurry used in the present invention is an innovative improvement on the composition and performance of conventional pearlescent slurry. The improved pearlescent slurry can not only meet the pearlescent effect required by conventional curtain fabrics, but more importantly, it gives the fabrics excellent anti-ultraviolet function after pearlescent treatment.

[0041] A mixed slurry consisting of nano pearlescent powder (the main component is mica), ultraviolet light absorber and acrylic emulsion is applied to the back of the base fabric. This coating can not only reflect light and absorb ultraviolet rays, but also enhance its elastic recovery ability by increasing the overall rigidity of the fabric.

[0042] As the main component of the coating, acrylic emulsion has good film-forming properties and elasticity, and can still maintain its flexibility and elasticity at high temperatures. At the same time, the cross-linking agent added to the coating enhances the mechanical properties of the coating through cross-linking, making the fabric more elastic and resilient.

[0043] (III) High temperature wrinkle treatment of base fabric

[0044] The base fabric after pearlescent scraping is subjected to high-temperature wrinkling treatment. The mechanical arm applies 0.2-0.3MPa of pressure to the base fabric at about 100-120 cycles of different frequencies per minute, and irregular wrinkles are initially formed through a 100°C steam pipe. Then, the irregular wrinkles are fixed through high-temperature shaping at 190-220°C, forming a wrinkling effect with a strong three-dimensional sense.

[0045] The surface area of ​​the base fabric is increased through irregular high-temperature wrinkling treatment. This treatment not only increases the three-dimensional sense and decorative effect of the fabric, but also effectively improves the resilience of the fabric.

[0046] The irregular wrinkling treatment creates more wrinkles and uneven structures on the surface of the fabric. The diversity of this structure helps to disperse stress at high temperatures and helps the fabric to quickly return to its original shape after being heated, thereby improving the overall resilience of the fabric.

[0047] (IV) Rebound treatment of base fabric

[0048] The elastic agent emulsion is evenly coated on the base fabric, and then dried and cured at 150-170°C for about 35-45s, so that the base fabric can still have good elasticity and maintain a good shape in a high temperature environment or after high temperature exposure;

[0049] The resilience agent emulsion is prepared by mixing and stirring 35-40 parts of acrylic emulsion, 0.5-1 part of cross-linking agent, and 60-65 parts of deionized water;

[0050] During the rebound treatment, a specially formulated rebound agent emulsion is evenly coated on the base fabric and then dried and cured at an appropriate temperature and time. This can create an "elastic memory" effect in the fabric, which means that the fabric can maintain good shape and elasticity in a high temperature environment.

[0051] Specific resilience solution and curing process ensure that the fabric does not lose its elasticity at high temperatures or prolonged exposure to heat sources, maintaining its original shape and function.

[0052] (V) Pleated treatment of base fabric

[0053] The base fabric after the rebound treatment is heat-set at a temperature of 95-105°C and a pressure of 0.45-0.55MPa. This heat setting can form permanent wrinkles on the fabric under high temperature conditions, making the curtains appear pleated, thereby obtaining high-temperature resistant and high-rebound pearlescent pleated curtain fabric.

[0054] The pleated structure not only increases the three-dimensional sense and aesthetics of the fabric, but also enhances the overall elastic recovery of the fabric through the resilience of the pleats. The pleated structure can quickly return to its original shape after being stretched or compressed, which is very important for maintaining the shape and elasticity of the fabric, especially when used in high temperature environments.

[0055] During the pleating process, the fabric is heated to 95-105°C. This high temperature treatment is equivalent to a heat aging test of the fabric. Through this treatment, the fiber structure of the base fabric is stabilized and strengthened, increasing its ability to withstand high temperatures. The fibers are rearranged and fixed under high temperature conditions, making the fabric less likely to deform or lose elasticity during subsequent high temperature use.

[0056] The pleated structure allows the fabric to rebound quickly after being subjected to external forces (such as stretching and compression) through the recovery force of the pleats. This elastic recovery performance is particularly important under high temperature conditions, because materials tend to soften and lose their original shape and elasticity under high temperature conditions. The pleated treatment not only strengthens the surface structure of the fabric, but also further improves the durability and stability of the fabric at high temperatures by increasing its elastic recovery ability.

[0057] The presence of the pleated structure allows the fabric to disperse these stresses more evenly when subjected to stress (such as stretching, compression or bending) instead of concentrating them at a certain point. This dispersion effect helps reduce fatigue damage to the fibers during use and prolongs the service life of the fabric. At the same time, evenly distributed stress can avoid permanent deformation or damage caused by stress concentration at high temperatures.

[0058] During the implementation of the rebound and pleating treatment of the present invention, it is necessary to innovate and optimize the conventional rebound slurry composition and pleating process. After many experiments, the optimal ratio of the rebound slurry and the optimal design of the pleating temperature and pressure are achieved to achieve better high-temperature resistance and resilience than conventional pleated curtains, as well as better durability.
