Embodiment 1
[0232] This example illustrates the use of an offset rotogravure printing machine to prepare two sheets of bath towels with a uniform discontinuous deposit of directly fixed chemical softener.
[0233] The reagents for preparing the softening solution are:
[0234] 1. Tallow diester chloride quaternary ammonium salt (ADOGEN SDMC), obtained from WITCO Chemical Company, Greenwich, CT.
[0235] 2. Polyethylene glycol 400, available from J.T. Baker Company of Phillipsburg, NJ.
[0236] 3. Isostearic acid (Century 1105, available from Union Camp, Wayne, NJ).
[0237] The 75% tallow diester chloride quaternary ammonium salt, 20% polyethylene glycol 400 and 5% isostearic acid are melted and stirred in a 140°F constant temperature container to prepare a soft solution, and then put into the gravure tank , So that the soft solution fills the recessed area of the rotary gravure cylinder.
[0238] The gravure cylinder structure includes a central hollow area suitable for circulating heating...

[0247] The reagents for preparing the softening solution are:
[0248] 1. Tallow diester chloride quaternary ammonium salt (ADOGEN SDMC), obtained from WITCO Chemical Company, Greenwich, CT.
[0249] 2. Polyethylene glycol 400, available from J.T. Baker Company of Phillipsburg, NJ.
[0250] 3. Isostearic acid (Century 1105, available from Union Camp, Wayne, NJ).
[0251] 4. Amino dimethicone (SF1921, available from GE Silicones, Waterford, NY).
[0252]Melt 33.8% tallow diester chloride quaternary ammonium salt, 9% polyethylene glycol 400, 2.3% isostearic acid and 55% SF1921 in a 140°F constant temperature vessel and stir to prepare a soft solution, and then fill it into On the gravure groove, make the soft solution fill the recessed area of the rotary gravure cylinder.

[0261] This example illustrates the use of an offset rotogravure printing machine to prepare two sheets of bath towels with a uniform discontinuous deposit of directly fixed chemical softener.
[0262] The reagents for preparing the softening solution are:
[0263] 1. Tallow diester chloride quaternary ammonium salt (ADOGEN SDMC), obtained from WITCO Chemical Company, Greenwich, CT.
[0264] 2. Polyethylene glycol 400, available from J.T. Baker Company of Phillipsburg, NJ.
[0265] 3. Isostearic acid (Century 1105, available from Union Camp, Wayne, NJ).
[0266] The 76% tallow diester chloride quaternary ammonium salt, 20% polyethylene glycol 400 and 4% isostearic acid are melted and stirred in a 140°F constant temperature container to prepare a soft solution, and then placed on the gravure tank , So that the soft solution fills the recessed area of the rotary gravure cylinder.
