- the respective amount of polyurethane may be up to 5%, or up to 10%, or up to 20%, or up to 30%, or up to 40%, or up to 50%.
- the textile substrates may be present in woven or non-woven form.
- oils and/or fats to be removed are, in particular, such oils and/or fats, which are applied in the manufacture of the textile substrate, such as fatty substances (in particular waxes, fats and/or oils) or also wax-containing preparation agents, which improve the dry machine processability (for example the re-spooling of yarns or the high-speed sewability of webs).
- oils and/or fats to be removed are mentioned: spinning additives, spinning oils, coning oils, chain smoothing agents, spindle oils, fats for ring travelers, sizings, spinning preparations, plasticizers, dry and wet glide agents, mineral oils or silicon oils, etc.
- a third aspect of the present invention relates to the manufacture of the compositions according to the invention comprising the following steps: if necessary, transferring a component of a solid physical state into the liquid physical state; mixing the components of the composition according to the invention.
- the step of mixing the components of the composition according to the invention may be performed in a mixing device which is suitable for said mixing.
- the N-methyl-N-acylglucamines are mostly solid at room temperature and, if necessary, have to be molten prior to the mixing.
- Humectol LYS (Trade product of the company Archroma Management GmbH)
- the test for analyzing the degreasing effect assesses the efficiency of the degreasing agent to remove mineral oil, respectively silicon oil, from polyamide/elastane (PA/EL) blends.
- mineral oil respectively silicon oil
- PA/EL polyamide/elastane
- the samples were dipped into a Mathis Labomat in an aqueous bath containing 4 g/L of degreasing agent and 1 g/L of soda (sodium carbonate), and were washed for a period of 30 min at 80 °C (heating rate 1 °C/min).
- the bath was drained and the samples were rinsed for a period of 10 min at 70 °C, 50 °C and 3 °C, respectively, were dried at room temperature and were in turn stored in an air- conditioned room for a period of four hours, and were subsequently weighed - W3.
- compositions according to the invention of Examples 1 to 4 exhibit a significantly improved degreasing effect compared to Comparison Example 1.
- Foaming behavior For analyzing foaming behavior, 1 g of degreasing agent dissolved in 500 mL of desalted water in a sample glass of a SITA R 2000 foam tester are tested with respect to the resulting foam build-up at a stirrer speed of 1 ,000 rpm. For this, the foam volume was measured in time intervals of 20 sec, respectively, over a time period of 30 min in total. The initial value after 20 sec and the final value after 30 min were documented and are represented for Comparison Example 1 and for Examples 1 to 4 in Table 2. The lower the value in mL, the better is the foam behavior.
- Example 4 32 mL 87 mL
- the compositions according to the invention of Examples 1 to 4 exhibit a significantly lower foam formation compared to Comparison Example 1.
