Shearling Nappalan Care - Kit-Sn4 by Leather Doctor is an innovative leather-safe (pH 3 - 5) system designed for keeping nappalan outer garment at their highest level of appearance, enhancing their softness and strength and prevents premature ageing. Smooth finishes over the suede when dry of its original fatliquor (ionic negative -ve charged fat and oil) are visually shown as creases and wrinkles especially at the elbow bends. Relaxing the creases and wrinkles begins with Hydrator-3.3. Increasing its suppleness with softness and strength follows with Fatliquor-5.0 (ionic negative charges fat and oil). The fat plumps the suede with fullness and the oil lubricates the fibers for smoothness during compressing, stretching and flexing thus reduces creases and wrinkles. Unlike conditioning oils that darkens suede, fatliquor seasons the suede to a richer tone that helps reduce the ingress of liquid stains and making soiling removal easier where the fibers is full of fat and oil. Maintenance cleaning before soiling build up on body contact areas is done with Clean-3.8 and Rinse-3.0 respectively. Protector-B (the leather-scented version is Protector-B+) imparts a non-stick rub-resistant buttery-feel that shields the effect of sticky soiling, keeping a high level of appearance for a longer period of time and reduces scuffing from friction rubs. The shearling wool inner face is clean, sanitize with odor control and rinse with CleanWool-5.5 and RinseWool-4.0 respectively. Protector-S or S+ (leather-scented) imparts a silky feel to the wool. Note that the mentioned product suffix number denotes its pH value in this leather-safe holistic care system for double face shearling nappalan. Shipping Weight Options comes in 'RTU' (ready-to-use) and 'Fill' (to be cut/mix and fill with distilled water prior to use) version to save on shipping.
A both sides cleaning begin with the inner wool face turning outside. When it is complete return and begins with the leather face.
Wool Face Cleaning and Conditioning:
Sequence-W1 - Dry Soil Removal - Instruction: W1-1) Vacuum off foreign soiling with help of suedeBrush-3 brushing at an angle. Proceed to Sequence-W2.
Sequence-W2 - Wet Soil Removal - Instruction: W2-1) Apply CleanWool-5.5, brush at a low slant and terry towel extract until it shows clean. W2-2) Spray RinseWool-4.0 and terry towel extract to a squeaky clean. W2-3) Let natural drying and dry towel wipe of wick-up soiling. Proceed to Sequence-W3.
Sequence-W3 - Non-Stick, Rub-Resistant Protection - Instruction: W3-1) Shake well, mist spray Protector-S/S+ evenly with brushing to redistribute deep. W3-2) When dry thereafter groom with suedeBrush-3 or a slick comb to bloom for best appearance. Return to the leather face and continue as follows:
Napallan Smooth Face Cleaning, Rejuvenating and Protection:
Sequence-N1 - Dry Soil Removal - Instruction: L1-1) Dry soiling is brushed with LeatherBrush-1.
Sequence-N2 - Wet Soil Removal - Instruction: L2-1) Apply Clean-3.8 and agitate with Brush-1 (horsehair) and terry towel extract until it shows clean. L2-2) Spray Rinse-3.0 and terry towel extract to a squeaky clean. L3-3) While still damp: Proceed to Sequence-L3.
Sequence-N3 - Hydrating - Hydrating is to relax the leather face of stiffness and creases from diminishing original fatliquor. Fatliquor (ionic charged fat and oil) diminishes as the skin ages, accelerated when expose to direct heat and evaporate as VOC (volatile organic compound) shown clearly on the elbow region. Hydrating is to precondition the leather prior to fatliquoring; it helps to relax and separate the stick together fibrils and opens up the inter-fibrillary spaces for effective colloidal water movement within the leather structure. It facilitates to wick-up foreign contamination to be towel extracted when damp and erased when crispy dry. It plumps the skin to ease away the unnatural creases and wrinkles. It stabilizes the pH integrity of the skin and charges the protein fiber ionic positive below its iso-electric point (pI) to hydrogen bond with the ionic negative fatliquor more effectively. It is recommended therefore to hydrate the skin to an optimum level, with moistures oozing out when gently pressed between thumb and fingers. Prolong dwell time will maximize the effects with the help of covering with clear plastic to prevent evaporation. Instruction: L3-1) Spray Hydrator-3.3 with foam brush control to hydrate the entire thickness of the leather. To remove unnatural creases and wrinkles especially the elbow regions, allow to dwell and to stretch to satisfaction. Extract with a dry absorbent white terry towel, inspect for an even appearance without blotchiness and it is ready for immediate fatliquoring. L3-2) Severe unnatural creases and wrinkles will require a longer dwell time of up to 72hours with evaporation control, covering with a clear plastic sheet. When the skin is plump, limp and lay flat, extract until towel shows dry or about 25% reading from a moisture meter and immediately proceed to Sequence-L4.
Sequence-N4 - Fatliquoring - Fatliquor-5.0 an emulsion of fat and oil originally introduces to the skin to impart its desired suppleness. The fat and oil content continues to diminish through evaporation as it ages, accelerated when exposed to heat. It diminishes through leaching as well in a non leather-safe solution and immersion cleaning, manifest as stiffness when the skin becomes dry again. Replenishing or rejuvenating is done with “fatliquor-in-a-bottle” as a spray-on instead of the original immersion method. Fatliquor, the lifeblood of leathers composition derives from fats, oils and water. When applies penetrates the skin and hydrogen bond with its protein fiber. The fat plumps the skin with fullness, the oil lubricates the individual fibrils and the encasing water breaks free leaving the inter-fibrillary spaces void for natural transpiration. Effective fatliquoring will leave a non-greasy or non-oily surface when dry. Besides softening the skin, fatliquor enhances its rip tensile strength greatly. It relaxes coarse breaks, creases and wrinkles and prevents cracking. It helps to keep the skin at its optimum physical performance and prevent premature ageing. Instruction: L4-1) Spray Fatliquor-5.0 with foam brush control for an even appearance. L4-2) Repeat application in between drying as the water contents evaporates until it’s saturated. L4-3) The fully saturated skin is left for slow natural drying. L4-4) Stretch and massage it before it is completely dry for extra suppleness.
Sequence-N5 - Non-Stick, Rub-Resistant Protection - Instruction: L5-1) Shake well, mist spray Protector-B (scentless) B+ (leather-scented) with Towel-5 to redistribute evenly. L5-2) When dry, it is ready-to-use.
Smartness of appearance may be improved with a low heat wool setting ironing. Place a white absorbent paper between leather and iron and iron for to improve appearance. Lacquer emulsion pigmented opaque finishes like Napa-84 system produces the best result then Micro-54 system or the transparent Aniline-76 system.
Hide/Skin Approximate Quantity or Percentage of Fatliquor: The quantities of fatliquor (fat and oil) contents retained in the skin after an universal modern tannery fatliquoring process may varies up to 14% depending on the leather types and it usage. This percentage drops as the fat and oil content diminishes or leaches through ageing, water, heat or chemical overexposure. Leather rejuvenating or fatliquor replenishing is base on weight of the skin in relation to the percentage of remaining fatliquor. A simple calculation of percentage of fatliquor topping up requirement would be as follows: If the weight of the skin in question is 100gm and fatliquor (fat and oil) content meter reading is less than 1%. By applying 80gm of Fatliquor-5.0 to it will deliver an end result incremental of 13.3% fatliquor when dry as the 66.6% water contents evaporates. In the skin rejuvenating Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system, Hydrator-3.3 plays an important role by relaxing, opening up the inter-fibrillary spaces, facilitating and redistributing colloidal water movement, protonating and doing all the pre-conditioning work prior to fatliquoring including cleaning up any excess surface remnants to have a sticky-free surface. In practice with severe dryness the ratio for Hydrator-3.3 are 2 to 1 of Fatliquor-5.0.It works out to be approximately 160gm of Hydrator-3.3 plus 80gm of Fatliquor-5.0 to replenish a 100gm dry leather from less than 1% back to the original tannery up to 14% fatliquor content.

The Lazarus Effect
Product Reviews - Posted by Larry Bauman on 31st Jul 2017
This product revived my 40 year old Sheepskin coat that cracked at the touch of it after applying another company's 'Restoration' product. That other product ruined my coat, and I was about to throw it away, but took a chance on the Leather Doctor. After applying Hydrater 3.3, I saw an immediate change. I then continued with the Fatliquor 5.0, and was shocked to see the change. My coat is now as soft and supple as it was when I purchased it in 1975! Don't even take a chance on valuable leathers with other companies' products, this one will amaze you sith its results.
