These differences in physical structure of the surface of rare animal fibers, compared with wool, will be at least partially responsible for the greater difficulty in processing mohair and cashmere, and will also contribute to desirable aesthetic advantages such as softness and lustre and different friction properties.Īs nutrition affects cashmere cuticle properties, it is not surprising that the fiber friction index ( Onions, 1962) indicated differences in friction between cashmere from different nutrition treatments ( McGregor and Liu, 2017). However, there is a general, if qualitative, acceptance that these fibers have flatter cuticle cell profiles, resulting in a smoother fiber surface. It is obvious from the above reports that considerable variation exists in the surface morphology of rare animal fibers. A more radial distribution of para cells. No demarcation of ortho/para distribution. At 25–35 μm ortho/para cells distribution becomes variable. If fine fibers are medullated, the bilateral structure remains. Camel hairs were investigated by Matsukawa et al. A slightly lower directional frictional effect was measured in Suri alpaca compared with Huacaya alpaca ( Table 4.3). The effect of scouring methods and chemical modifications, such as chlorination and buffering, on fiber friction coefficient and the differential fiber friction for mohair and cashmere were investigated by Holt (1995). It was suggested that it was not inherent differences between the mohair and wool fibers, as such, that influenced the yarn friction but that it was extractable matter (grease, additive applied during processing, etc.) present on the mohair that adversely affected the performance of the paraffin wax. By scouring or extracting the yarns with a solvent prior to waxing, the yarn friction, subsequent to waxing, could be reduced considerably and became approximately independent of the mohair content of the yarn. It was found that the friction of waxed mohair/wool blend yarns actually increased with increasing mohair content. Hunter and Kruger (1972) examined mohair yarn friction. Smuts and Slinger (1972) related fiber friction in mohair to fabric handle. (1948) reported the lower friction and lower differential friction of mohair due to less-prominent cuticle scales. Martin and Mittlman (1946) and Frishman et al. So unless it keeps tripping a DTC it eventually just goes out after the battery gets disconnected.As mohair differs from wool in frictional properties, the property has attracted some research attention. It’s only a one trip DTC so it only trips it once.

Auto Zone didn’t pick it up after that but then I plugged in with Nissan software and there it was P0325.

But enhanced scanning or vehicle make specific scanning like a tech II for GM may pick it up as a generic code scanner may not. If It’s a Detonation Sensor you probably could clear it by just disconnecting the (-) battery cable. Depending on the year of vehicle you are looking to buy, an old OTC genisys platform may be the way to go, though they were not all that great to begin with. That keeps codes stored until the tests have reran and self cleared. Now the newest vehicles out there have a mode$10. Used car lots who play the erase game get into a bind as it has to pass first. In Denver, when you go for an emissions test, ’05 and newer, they are looking for completed monitors. If it is a ford product and OBDII, then you get a P1000 until the monitors complete. If they aren’t complete, then I know the codes have either been erased recently, or power to the PCM has been interrupted(intentional maliciousness or accidental). I check for codes, then I go to the readiness monitors. Now when we get a vehicle in for a pre-purchase inspection, I play detective(you have to in this business) and start snooping. That’s about how useful those cheap scanners are. I do a complete system scan, and find 4 current faults and a pending fault in the PCM, and 3 more faults in the ABS module. vAutozone scanned it, and only saw one code, and they speculated that the VSC was on due to the PCM code(it can do that). CEL was on, as well as the VSC lights(Toyota).

Just last week, I looked over a vehicle, full shake down inspection so he could decide if it’s worth fixing. You often deal with non-emissions modules that can set codes and the cheap scanners will not show anything. Some codes will only show themselves with a scan tool with enhanced OE capability. Any scanner without enhanced data capability will leave you in the dark.
