- PVP polyvinylpyrrolidone
- the current general pre-treatment procedure for textiles comprising cellulosic fibers by Pad Steam application requires high amounts of caustic soda (NaOH) for scouring (25-50 g/l NaOH (solid)) and/or bleaching, i.e. saponification of natural cotton waxes and fatty substances.
- CaOH caustic soda
- Such high amounts of NaOH in combination with Pad Steam conditions are often harmful to the cellulosic fiber and can lead to reduced fabric strength, i.e. tensile and tear strength, and depolymerization of the cellulosic molecular chain, i.e. a chemically damaged fiber.

- the residual monomer content in the PVP polymer is below 0.01% by weight.
- the activity of the pectate lyase used herein was measured according a test method from DuPont Industrial Bioscience (C401-00). The principle of this test method is based on the fact that pectate lyase catalyzes the formation of double bonds in polygalacturonic acid, which can be read with an UV/VIS-Spectrophotometer at 235 nm wavelength. The double bond formation is proportional to the enzyme activity. The activity is displayed in PLU/g pectate lyase, which can be calculated out of the product between the standard equivalent curve (PLU/ml) and the sample dilution divided through the weight of sample (g).
- PLU/g pectate lyase PLU/g pectate lyase
- the pectate lyase is combined with a non-ionic detergent, a sequestering agent, chelating earth alkalines (Ca, Mg) and heavy metals (Fe) and, optional an alpha-amylase breaking down starch size on cotton woven fabrics.
- compositions were used in the Examples: Table 2: Compositions used in the Examples.
- Compositions A, B, C and E are reference examples.
- Optise ® NEXT liq. alpha-amylase
- Example 1 Determination of crease (lay) mark inhibition during Pad Steam application 100% cotton woven fabric (CM50xCM50/150x80) was impregnated (liquor pick up 100%) with a composition according to Table 2 and steamed for 20 min at 80°C.
- the wet crease angle recovery was directly measured after steaming.
- the test method followed a procedure described in AATCC 66-2003, option 2 on wet fabric, whereas a fabric sample of 40 x 15 mm was folded end-to-end, exposed for 5 min at room temperature with a 500 g weight on top and afterwards the recovery angle from a circular scale in degree (°) was evaluated.
- Table 3 Wet crease recovery angle according to AATCC 66-2003, option 2.
- the evaporation test followed a procedure described for evaluation of moisture management properties according to the test method from M&S (Marks & Spencer).
- a conditioned specimen was weighed and afterwards exposed to 1.0 ml of distilled water in a petri dish. Then the weight of the specimen was evaluated after each 5 min up to 30 min time. The remaining water in the fabric was calculated in % with regard to the initial weight (at 0 min) of the fabric.
- Table 4 Liquor retention ability according to M&S (Marks & Spencer).
- the ability to retain more liquor and humidity during steaming on the textile also has a favorable impact on avoidance of crease and lay marks, since higher amounts of humidity (liquor/water) remain on the textile after impregnation. This avoids too fast drying up of fabric parts directly exposed to the steamer atmosphere and also minimizes the chemical damage of the fabric after steaming.
- Example 3 PVP in continuous pre-treatment: Performance improvement during alkaline scouring and H 2 O 2 -bleaching (Pad Steam).
- the performance of the process according to the invention, respectively the performance of the composition according to the invention used in the bio-scouring step can be determined using a Ruthenium Red dyestuff solution applied to the textile after treating the same with the composition according to the invention, which indicates the amount of pectin remaining on the cotton fiber.
- the absorbency level was measured according a modified AATCC test method (197-2012-Vertical Wicking of Textiles, Clariant Internal Test Method TM 7302) or the drop test method according to TEGEWA: a drop of colored water was placed on the surface of the fabric and the time was evaluated (in sec.), until the drop had been completely absorbed up from the fabric and b) according the wicking height method, whereas a sufficient amount of dye solution was filled into a Petri dish, minimal height 15 mm. Then the textile test stripes were suspended in the dye solution so that the bottom end just penetrated the surface of the solution. The stripes were dipped for approximate 2-3 mm. The time was evaluated with a stop watch and after 5 min, the stripes were removed and dried between layers of absorbent paper.
- Table 5 and Table 6 show that addition of PVP polymer leads to better performances in terms of whiteness and absorbency levels. The higher the wicking height and the shorter the time of the drop test, the better the absorbency of the fabric.
- Tensile strength was determined according to ISO 13934-1. A test specimen is extended at a constant rate until it ruptures. The maximum force at rupture is recorded. The higher the value (force) or the more close the value compared to the untreated, grey fabric, the better the performance. Table 7: Tensile strength improvement during Pad Steam processing (determination after scouring & bleaching).
- Table 7 demonstrates that the tensile strength of the textile is clearly improved in the presence of PVP compared to the reference processes.
- the dryed textile samples were then dyed in a Launder-O-Meter (LOM) at liquor ratio 20:1 at 50°C for 30 min in 250 ml of a 0.05% w/w Ruthenium Red staining solution in phosphate buffer at pH 6.0. After dyeing, the samples were washed off with warm demineralized water, dried and then, color strength (%) and color difference (dE*) were measured with Datacolor Spectrophotometer 650. Table 8: Continuous bio-scouring effects.
- LOM Launder-O-Meter
- pectate lyase in combination with PVP polymer leads to a reduced color strength of Ruthenium Red and minimizes color difference compared to the untreated, grey fabric, demonstrating the improved bio-scouring effect in the continuous pre-treatment.
