Description

Technical Field

[0001] The invention belongs to the technical field of textile anti-wrinkle fabrics, and in particular relates to a processing method of formaldehyde-free dry physical anti-wrinkle fabrics. Background Art

[0002] At present, people's daily business needs have higher and higher requirements for wrinkle-resistant clothing. However, most wrinkle-resistant clothing is achieved through two methods: non-ironing fabric and non-ironing garment. In essence, it is finished with non-ironing resin finishing agent to give the fabric wrinkle resistance. Formaldehyde and aging formaldehyde will be generated during the production process, and the formaldehyde pollution generated by the non-ironing fabric is particularly serious. Therefore, the development of a highly wrinkle-resistant formaldehyde-free fabric is an urgent need shared by the market and the industry. There are some reports on wrinkle-resistant fabrics.

[0003] Chinese invention patent CN113089157A discloses a processing method for comfortable and wrinkle-resistant fabrics, which is made of pure cotton or cotton-based blended materials, and the wrinkle resistance of the fabric is improved by liquid ammonia, mercerizing and other finishing processes in the form of super-high twist of the strands. Chinese invention patent CN116657328A discloses a wrinkle-resistant and shape-keeping polyester fiber fabric and its preparation method, which uses polyester fiber to be processed into fabric by needle punching process instead of weaving process. Chinese invention patent CN115852558A discloses a production method for natural wrinkle resistance of cotton and lyocell fiber blended fabrics, which mainly uses cotton lyocell blended as raw material, and the yarn is naturally wrinkle-resistant to 2.9 through finishing process, and its wrinkle resistance level needs to be improved. Chinese invention patent CN113832710A discloses wrinkle-resistant fabrics and their preparation methods, which mainly achieve wrinkle resistance through finishing auxiliaries, and the second purpose is to improve the antibacterial properties of the fabric, and lacks data support on formaldehyde-free and high wrinkle resistance. The wrinkle resistance of fabrics reported in the above patents is mainly achieved through or in combination with post-finishing processes, which cannot meet the market demand for formaldehyde-free, high wrinkle resistance, and multi-functions. Moreover, the process focuses on post-finishing to achieve wrinkle resistance, and the process is relatively cumbersome. Therefore, it is urgent to develop a simple, efficient, environmentally friendly, green and highly wrinkle-resistant fabric processing method. Summary of the invention

[0004] The purpose of the present invention is to provide a processing method for formaldehyde-free, dry, physical anti-wrinkle fabrics. The present invention mainly utilizes the anti-wrinkle performance of the fiber itself, the rigidity of the high-twist yarn, the low curvature of the yarn in the fabric, and the change of the fiber morphology by liquid ammonia molecules to comprehensively achieve natural anti-wrinkle performance of level 3.7 or above. At the same time, the low curvature and high-twist yarns can increase the porosity of the fabric, accelerate the air flow between the skin and the fabric, and give the fabric natural high air permeability and natural cool performance, making it dry and not sticking to the skin.

[0005] The technical solution of the present invention is as follows:

[0006] The processing method of the formaldehyde-free dry physical anti-wrinkle fabric of the present invention comprises the steps of yarn raw material selection, yarn pre-treatment, weaving process and post-finishing process.

[0007] The yarn raw materials include 30-65wt.% polyester fiber of the first yarn raw material and 35-70wt.% of the second yarn raw material, which are blended into compact yarn to obtain 100-200dtex yarn, and the twist coefficient of the yarn is 300-400; the second yarn raw materials include viscose fiber, regenerated cellulose fiber, flax fiber, wool, silk, and cotton; the compact spinning method with compact yarn, smooth appearance and less hairiness is adopted, and the compact yarn structure has higher strength, good rigidity and toughness, and is not easy to produce hair abrasion during the weaving process.

[0008] The yarn pretreatment includes the following processes: (1) yarn dyeing: double-bath dyeing of the yarn; (2) yarn twisting: twisting the yarn in the reverse direction of untwisting by 15-75%; (3) yarn steaming: steaming the yarn in a steam environment of 95-100° C. for 60-65 minutes in two cycles without boiling the yarn.

[0009] Preferably, the yarn twist coefficient after pretreatment is 430-700.

[0010] The weaving process includes warping, sizing and weaving processes.

[0011] Preferably, the warping process: when starting the machine, the warp beam frame tension is 0.15~0.2MPa.

[0012] Preferably, in the sizing process, the wet elongation in the sizing tank is greater than 0.55%, and the dry zone elongation in the sizing yarn is greater than 0.7%, so as to prevent the warp yarn from twisting and kinking. In the sizing process of the present invention, polyvinyl alcohol and starch are mixed in a mass ratio of 4:6 to 6:4 for sizing, wherein the polyvinyl alcohol adopts completely alcoholyzed polyvinyl alcohol, and the starch adopts phosphate starch. The mixed slurry in this ratio has good adhesion, prevents the shedding of the sizing film due to the difficulty in dry twisting, and can effectively reduce the tendency of twisting and kinking. At the same time, the yarn needs to maintain a certain tension when entering the sizing tank.

[0013] Preferably, the weaving process: the warp weaving tension is ≥1600N, the machine speed is >500r / min, and the yarns are kept intersecting in a straight line on the grey cloth through high tensile tension and weft drafting force to reduce bending; the weaving uses three-primary structures with an average float length ≥1.5, including twill and satin, which can improve the wrinkle resistance of the fabric; the total tightness of the finished product is 80%~90%.

[0014] The post-finishing process includes singeing, desizing, pre-stretching, liquid ammonia, stretching, and pre-shrinking processes.

[0015] Preferably, the desizing process is: stacking for 5-10 minutes in a steam environment at 90-100°C, desizing at a speed of 85-90 m / min through a water washing temperature of 90-95°C and a steamer temperature of 90-100°C; the working liquid preferably includes 20-30 g / L of high-temperature enzyme, 5-15 g / L of refining agent, and 2-5 g / L of penetrant.

[0016] Preferably, the pre-stretching process: in order to reduce the risk of static electricity generated by friction of polyester fibers, it is necessary to pre-stretch through a material trough with 5-10g / L antistatic agent added, the pressure of the rolling car is set to 0.7~0.8MPa, the speed is 50~60m / min, the rolling rate is controlled to 45~55%, and the residual additives are washed away through a water washing tank. The purpose is to make the fabric pass through the liquid ammonia process safely and evenly, and effectively improve the wrinkle resistance of polyester fibers and other fibers.

[0017] Preferably, the liquid ammonia process: washing, drying, air cooling and then rolling the liquid ammonia at a speed of 20-40 m / min.

[0018] Preferably, in the tentering process, the difference between the width of the finished product and the width of the grey fabric off the machine is ≤7%, and the drying temperature is 90-100°C to reduce the bending of the weft yarn in the fabric.

[0019] Preferably, the preshrinkage process: rubber blanket pressure 0.3~0.5MPa, rubber blanket temperature 100~120℃, wool blanket temperature 100~120℃, vehicle speed ≥60m / min, so that the fabric passes through at a fast speed and high pressure to reduce the shrinkage of the warp yarn to meet the low bending state of the yarn and achieve the purpose of stabilizing the length and width of the fabric.

[0020] Compared with the existing technology, the present invention has the following beneficial effects:

[0021] 1. The present invention uses a single yarn with a special twist to improve the yarn toughness. Combined with the three-primary structure, the wrinkle recovery performance of the fabric is improved. The fabric has a flatness of 3.7 or above after washing according to the AATCC 124-2018t standard test;

[0022] 2. Compared with woven fabrics of the same specifications, the yarn structure fabric of the present invention has a large porosity, no chemical additives such as formaldehyde resin, good natural air permeability, natural coolness, water absorption and quick drying, and is green and environmentally friendly;

[0023] 3. The post-finishing process of the present invention has strong production feasibility and high cost performance. At the same time, the fabric has high strength, a dry hand feel, and good shape retention and wrinkle resistance. BRIEF DESCRIPTION OF THE DRAWINGS
