The cotton-like fabric and the hemp-like fabric which are common in the market at present have the appearance and touch of cotton threads or hemp threads by carrying out specific process treatment on yarns. The production of the fabric is relatively mature, and the yarn treatment process is standardized. However, the cotton-like and linen-like fabrics imitate the characteristics of cotton threads or linen threads only on the yarn level, and the overall texture style of the fabrics does not have the characteristics of natural materials.
In contrast, the linen-like fabric is not only treated on yarns, but also required to exhibit an overall texture style of natural linen after the weaving is completed. The linen-like fabric has a texture similar to that of hand knitting in visual sense, has a certain rough and natural appearance, and has high requirements on the knitting process.
At present, no fabric capable of truly simulating the style of linen exists in the market. The linen-like fabric is knitted, so that not only is a proper yarn material selected, but also a complex texture effect is realized by an accurate knitting method. Particularly, how to keep the structure of the fabric stable and simultaneously present irregular but natural textures is a great difficulty in the technical field.
Therefore, development of a fabric imitating the style of the linen needs to have the natural appearance of the linen, solve the defects of the natural linen in light fastness, mildew resistance and waterproofness, and ensure the cost performance through mass production, so that the fabric is a subject to be broken through in the technology.

Detailed Description
The present invention is further described below.
The manufacturing method of the rolling curtain fabric with the natural grass style mainly comprises the following steps, wherein each step is carefully designed to ensure that the final product has high cost performance, excellent light fastness, moisture resistance and environmental protection. The following are detailed process steps and explanations of each detail:
1. braiding of body facings
The method and the process are as follows:
The leno heald weaving method with regularly spaced and hollowed warp direction includes weaving the main body fabric alternately via four leno heald paths to form hollowed warp direction with interval of 19 mm. The leno heald weaving method ensures that the fabric structure is stable, has a style similar to hand weaving, and increases the air permeability and the aesthetic property of the fabric.
The two adjacent weft yarns are respectively three-in-one fancy twisted yarn and fancy composite yarn.
The loom is an imported multi-denier heavy-weight rapier loom, and guarantees the weft insertion and weaving stability of the coarse open yarns.
And (3) material selection:
300D bright twisting yarn is selected as warp yarn. The compactness and the gloss of the fabric are increased, so that the fabric is more similar to the effect of hand knitting.
The three-in-one fancy twisted yarn adopts 150D white yarn, 150D irregular section dyed yarn and 8 irregular bamboo joints. The combination forms a special fancy bamboo joint style, and creates the visual effect of natural hemp.
The fancy composite yarn is formed by mixing 1050D fancy space dyeing composite yarn and 2400D masterbatch fancy composite yarn according to the proportion of 1:1:4 and weaving the fancy composite yarn in a grid-connected mode through a grid-connected machine, so that the composite yarn with layering sense and clear color is formed, and the texture is rough and similar to paper.
In the processing of fancy composite yarns, air pressure and vehicle speed are key factors influencing the final style effect of the style of the composite yarns and the inherent mechanical properties. In general, the optimum combination of air pressure and vehicle speed can be determined by experimentation and observation to achieve the optimum processing results and production efficiency.
Proper air pressure can form tight entanglement between the fibers and improve the network degree, thereby enhancing the cohesion and the overall strength of the fibers. Too low air pressure, insufficient entanglement of fibers, may result in insufficient network, affecting subsequent processing and performance, and too high air pressure, may result in excessive entanglement and even breakage of fibers, while increasing equipment wear.
The speed of the vehicle determines the residence time of the fibers in the grid-connected machine, thereby affecting the entanglement effect of the fibers. The fiber has the advantages of high speed, short residence time of the fiber in the grid-connected machine, insufficient entanglement, and low speed, and can improve entanglement effect, reduce processing efficiency and increase production cost.
According to the invention, through the optimal design of the orthogonal test, the air pressure of the grid-connected machine is set to be 0.7MP, the vehicle speed is 50 m/min, and the degree of networking and the entanglement effect of the composite yarn processed by the mixed grid-connection are optimal.
Advantages are:
the multi-layer visual effect is that the combination of different yarns enables the fabric to present rich color and texture effects, and the three-dimensional sense and the decoration of the fabric are enhanced.
The tight cloth cover structure, namely the leno heald weaving method ensures the tightness of the cloth cover, is not loose, improves the durability and tear resistance of the fabric, and is very suitable for high-strength roller blinds.
2. Weft setting process
Description of the procedure:
Weft finishing shaping, namely before sizing, weft finishing shaping is an important step for ensuring the evenness of the cloth cover and the consistency of the warp and weft directions. Control of this process is critical to the effectiveness of the subsequent sizing.
The specific operation is as follows:
And selecting equipment, namely adopting an automatic weft straightening and shaping integrated equipment line, wherein the weft straightening equipment adopts an intelligent Germany EL Laimer weft straightening machine.

This arrangement helps to avoid deformation or shrinkage of the fabric due to too high or too low a temperature.
Radian control, namely controlling the warp, weft, skew and arc of weft to be less than or equal to 0.5 percent (namely 0.5 percent of the width of the door) after weft finishing so as to ensure the flatness and the dimensional stability of the fabric.
Advantages are:
The flatness and dimensional stability of the fabric are ensured, the optimal state of the fabric before sizing is ensured through accurate speed and temperature control and careful management of radian, and the processing difficulty caused by unevenness or dimensional change in the subsequent process is avoided.
3. Double-sided integral slurry dipping process
The process comprises the following steps:
The slurry is prepared by mixing and stirring 35-40 parts by mass of polyurethane emulsion, 15-20 parts by mass of acrylic ester emulsion, 50-60 parts by mass of deionized water and 0.5-0.8 part by mass of defoamer. Polyurethane provides softness and wear resistance, and acrylic acid improves the hardness and waterproof performance of the fabric.
And padding, namely uniformly coating the slurry on two sides of the fabric in a padding mode, and then drying, shaping and packaging.
The specific operation is as follows:
Sizing, namely uniformly penetrating the sizing liquid into the fibers of the fabric in a padding mode, so as to ensure uniform and consistent coating thickness of the fabric.
Advantages are:
The combination of polyurethane and acrylic acid not only enhances the waterproof property and the wear resistance of the fabric, but also ensures that the fabric has better light fastness and is suitable for the environment exposed to sunlight for a long time.
The soft hand feeling is maintained, and the softness is maintained even though the fabric is subjected to slurry dipping treatment, so that the fabric has durability and good hand feeling, and is suitable for manufacturing high-quality roller shutter products.
4. Drying process
And in the drying process, the temperature and time are controlled to fully evaporate the water in the slurry, and the polyurethane and acrylic acid components are uniformly adhered to the surface of the fiber, so that the shaping effect is achieved.
The drying treatment is divided into three stages of pre-drying, baking and cooling, wherein 1-4 sections are pre-drying sections, the temperature of the baking sections is 80 ℃ per 100 ℃ per 120 per 150 ℃, and the drying treatment mainly has the effects of uniformly evaporating most of water in the foaming slurry and controlling and keeping the surface of the coating from forming films;
The sections 5 to 8 are baking sections, the temperature of the baking oven is unified to be 180 ℃, the impregnated sizing agent at the stage can be crosslinked to form a film, and the impregnated sizing agent can be sufficiently dried to avoid the problems of stickiness and the like;
The 9-12 sections are gradient cooling sections, the temperature of the oven is 160 ℃ per 140 ℃ per 110 ℃ per 80 ℃, and the effect of the gradient cooling sections is to avoid overlarge temperature difference between the inside and the outside of the oven and generate thermal stress in a fabric organization structure or yarn, so that the flatness and the dimensional stability of a final finished product are affected.
And finally, winding the fabric into a semi-finished product of the roller shutter, and preparing subsequent finished product processing.
