• finishing process can be carried out mechanically (e.g. emerizing, compressive shrinkage, shearing) or chemically and provides to the product its final appearance and properties.
• Chemical finishing consists of the modification of textile fibers through chemical action. Chemical finishing is typically carried out by padding, during which the textile is fully immersed in a textile finishing composition and subsequently subjected to repeated cycles of drying (typically by exposure to IR), fixation (typically by using a high temperature fixation frame) and condensation.
• the padding process leads to considerable use of resources, such as finishing compositions, water and energy.
• the chemical finishing treatment can impart to the textile a wide variety of properties, such as softness, water-repellence, improved wicking properties, UV-blocking properties, and flame retardancy properties.
• a textile softening composition is a textile finishing composition, which makes the textile soft, fluffy and anti-static, thereby providing it with a soft hand.
• a textile softening composition contains a softener or a softening agent, which reduces the friction coefficient between fibers leading to the surface softness and lubricating effect on fibers.
• silicones including epoxy or/and amino-modified polysiloxanes, polyether-modified polysiloxanes, which contain polyether active groups grafted on the side chains of polysiloxane chains, and linear multiblock polysiloxane copolymers, are widely used as softeners or softening agents in a textile softening composition to impart softness to and improve the wear feeling of the treated textile.
• Silicone softening agents are synthetic compounds, the synthesis of which generally requires a lot of energy.

• a 1000 kg batch of a second silicone-free and fluorine-free composition having the composition depicted in the table below was prepared as follows: The following ingredients were introduced stepwise (i.e. one after the other in the indicated order) in a high energy dispenser (2000 L capacity) and stirred at the indicated speed and temperature for the indicated time period:
• the finishing process was performed using a commercially available industrial textile printer Panthera D8 (Supplier: Swiss Performance Chemicals) and subsequent calendar roll to roll (Model RTR-2760-H, Supplier: Eastsign).
• the Panthera D8 printer is equipped with 8 water-based Kyocera KJ4B-0300, DOD IJ Piezo Print heads.
• the textile finishing composition according to example 4 was printed by piezoelectric drop-on-demand ink jet (printing resolution 600x600dpi, 2 passes; printing speed 250 m 2 /h; wet deposit: 15 g/m 2 ) on a surface of a white color textile (Reference number: W-2017-992; 100 % PES; knitted) and of a pink color textile (Reference number: W-2017-993; 100 % PES; knitted).
• the printed textiles were dried by exposure to hot air (120 °C) for 90 seconds. Subsequently, the dried textiles were calendared for 35 sec at 205 °C to provide the finished textiles T1 and T2 according to the present invention (T1 - white color, T2 - pink color).
• the wicking properties of the finished textiles T1, T2, C1 - C4 were evaluated in the water drop test method AATCC 79, where the absorption time in seconds was measured prior to washing, and after 1, 5 and 10 washings (laundering test ISO 5077/3759/6330; Detergent ECE 98 -20 g), respectively.
• the water drop test method AATTCC79 also known as absorption time - dropping test, is conventionally used in the textile industry to measure the absorption time of a drop of water by the textile fabric.
• the textile fabric is held in a mandrel and a drop of water (0.1 mL) is deposited with a micropipette on the surface of the fabric.
• the time required by the textile fabric to absorb the drop is measured.
• the absorption time is a measure of the wicking propeties of the textile fabric.
• the two finished textile fabrics T1 and T2 according to the present invention present better wicking properties and wash durability (absorption time lower than 1 second even after 10 washings) than the finished textile fabric C4 finished by padding with a standard padding composition.
• the comparable properties of the finished textile fabrics T1 and T2 show the versatility of the textile finishing composition and the textile finishing process. Comparison of the adsorption time measured for the finished textiles C1 and C2 and the finished textiles T1 and T2 demonstrates that the calendaring step is essential for fixing the finishing composition to the textile fabric. Comparative finished textile C3 that was not printed with a textile finishing composition presents poor wicking properties as evidenced by the absorption time superior to 30 seconds.
• the textile finishing composition according to example 3 was printed by piezoelectric drop-on-demand ink jet (printing resolution 600x600dpi, 2 passes; printing speed 250 m 2 /h; wet deposit: 15 g/m 2 ) on a surface of the three different textile fabrics indicated below.
• the printed textiles were dried by exposure to hot air (120 °C) for 90 seconds. Subsequently, the dried textiles were calendared for 35 sec at 205 °C to provide the finished textiles T3 - T5 (T3 - finished 1 st fabric, T4 - finished 2 nd fabric, and T5 - finished 3 rd fabric) .
• the wicking properties of the finished textiles T4 - T5 were evaluated in the above-described water drop test method AATCC 79, and in the test method for vertical wicking rate of textiles AATCC 197 (effects were measured at 30 minutes).
• Test method AATCC 197 is generally used in textile industry to evaluate the ability of fabric specimens to transport liquid vertically when a cut edge is submerged.
• the determined vertical wicking rate represents a measure of the textile wicking properties. Cut edges of samples of the finished textiles T3 - T5 (14.0 x 2.5 cm) were submerged in water for 30 minutes. The samples were submerged both in the warp and in the weft direction. The height of the water absorbed by the samples (wicking distance) after 30 min was measured. Wicking distances at 30 minutes superior to 13 cm are indicative of textile fabrics having excellent absorbency and wicking behavior.
• Finished textile fabrics T3 - T5 according to the present invention show excellent absorbency (AATCC 79, absorption time ⁇ 1 second). Finished textile fabrics T3 - T5 also show excellent wicking behavior (AATCC 197) and meet the absorbency requirements of at least 13 cm for the wicking height at 30 minutes.
• the tests conducted in two directions of the fabric in warp and weft illustrate the excellent wicking behavior of the finished textile fabric according to the present invention.
• the wicking properties of the three tested textile fabrics are comparable, showing the versatility of the textile finishing composition and of the finishing process.
• the textile finishing composition according to example 2 was printed by piezoelectric drop-on-demand ink jet printing resolution 600x600dpi, 2 passes; printing speed 250 m 2 /h; wet deposit: 15 g/m 2 ) on a surface of a variety of different textile fabrics including 100% cotton twill at a density of 160 g/m 2 and a fabric garment blend 70% cotton/30%polyester at a density of 110 g/m 2 .
• the printed textile fabrics were dried by exposure to hot air (120 °C) for 90 seconds and subsequently, calendared for 35 sec at 205 °C to provide the finished textile.
• the softness of the finished fabric was evaluated by an expert by hand touch prior to washing and after 5, 10 and 20 washings, respectively. Compared to the untreated textile, the finished textile exhibit an excellent softness. The softness is maintained after 5, 10 and 20 washings.
• the textile finishing composition according to example 1 was printed by piezoelectric drop-on-demand ink jet (printing resolution 600x600dpi, 2 passes; printing speed 250 m 2 /h; wet deposit: 15 g/m 2 ) on a surface of the three different textile fabrics indicated below.
• the printed textiles were dried by exposure to hot air (120 °C) for 1 minute. Subsequently, the dried textiles were calendared for 3 minutes at 205 °C to provide the finished textiles T6 - T8 according to the present invention (T6 - finished textile fabric A, T7 - finished textile fabric B, T8 - finished textile fabric C).
• the water repellence of the finished textiles T6 - T8 and of the corresponding untreated textile A-C was evaluated in the AATCC 22 test method using the commercially available spray rating tester TF160 (supplier: Testex). Three samples were evaluated for each of the textile fabrics A, B and C.
• the sample of finished fabric held in a mandrel is sprayed with water.
• the sample is oriented at 45° with respect to the nozzle head of the spray rating tester and positioned at a distance of 150 mm under the nozzle.
• the appearance of the sprayed finished fabric is compared with the appearance of the finished fabric (not sprayed) by an expert and based on visual standards, a visual rating is given to the finished fabric.
• a visual rating of 100 indicates that the textile fabric preserves its initial aspect (i.e. no visually detectable difference between the appearance of the textile fabric prior and after the spraying) and no water was absorbed by the textile fabric during the experiment i.e. the textile fabric has excellent water repellence.
• the finished textiles according to the present invention provide excellent water repellency even after 20 washings.
• the rating of "100" indicates no absorption of water by the tested fabric.
• the water repellency does not decrease after 1 wash, 5x washes, lOx washes and 20x washes, which confirms the excellent wash durability of the finishing obtained with the inventive finishing process. Comparable results were obtained for the three fabrics attesting the versatility of the water-repellent finishing composition and the finishing process according to the present invention.
• finishing compositions were printed bidirectionally at 240 m 2 /h on a white color textile fabric (Natt6 2/1, 100% PES, 218 g/m 2 ) without using automatic cleaning up program.
• Different lengths (20 m, 100 m, 200 m, and 500 m) of textile were printed and the quality of the printing was visually checked.
• a prime test was conducted prior to printing each of the desired lengths (20 m, 100 m, 200 m and 500 m) to check whether all nozzles are correctly ejecting, as well as after printing each of the desired lengths to detect potential nozzles clogging.
