Nylon 6 monofilament

Characteristics of the Hysteresis Loop and Stress Wave in the Nonlinear Viscoelastic Response to the Sinusoidal Straining. Figure 3 is a schematic of a hysteresis loop obtained when a nylon 6 monofilament was subjected to a sinusoidal straining with yo = 1% and Ay = 1% at 90°C under a frequency of 10 cycles per sec.

Nylon monofilaments have found application in brush tufting, wigs, surgical sutures, sports equipment, braiding and outdoor upholstery. Nylons 610 and 11 have found extensive application in these fields because of their flexibility but nylon 66 is also used for brush tufting less than 0.0035 in. in diameter. Nylon 66/610 copolymer is used in the manufacture of a monofilament for angling purposes. 

After the polymer is formed, the filament is produced by extrusion. The nylon can be taken directly from the polymerization process while it is still molten. Alternatively, previously dried nylon chips can be heated and melted. The molten nylon is pressed through a spinneret, which is like a showerhead with 10—100 holes. (A spinneret with a single hole produces a monofilament. Nylon monofilaments are used for fishing line and sheer... 

Rorosity, 0.02 /im mean pore size, Hoechst-Celanese Corporation, Charlotte, fC) filled with a 300 /im dia. nylon monofilament (F) and connected to end-flared 300 pm i.d. in/out PTFE tubes (TT) through which the scrubber liquid (in the present case, water) is pumped. The membrane tube is suspended concentrically within a PTFE jacket tube TJ (5 mm i.d. and maintained in a linear configuration by an external rigid tube, not shown). Air is sampled through the tee-ports PT and end-seals are provided by a series of nested plastic tubes (NP). Greater details of construction are available elsewhere (12). This D.S. was used for the H2C>2 translation system (hereinafter called system 1) with an active membrane length of 40 cm.

A nylon monofilament fr manufactured as described above, with T = 550 K and a = 0.2 m. It is to have a final diameter of 100 lim and to be produced at the rate 5 ms . Under optimum conditions the i on crystallizes at 420 K under a true stress of 10 Pa. Find the required value of Ug and hence the required die diameter if the die swell is 13. (Take the shear viscosity of nylon to be 100 Pas at 550 K and the activation energy to be 40 kJ mol ) As the tube of Problem 7.12 is otruded, it is hauled off under tension, and inflated in order to maintain the diameter constant. Jets of cold air induce crystallization (the frost-line ) a distance 1 m downstream of the die. By this point the tube has been drawn down to a wall thickness of 50 /tm. Find the required tension in the tube and the internal air pressure required. (Note ignore natural cooling between the die and fix>st line, and assume Newtonian behaviour with an elongational viscosity of 24 kPas.) Refer to Problems 7.2 and 7.3. 

The classical work of Borroff and Wake in 1949 on the adhesion between the textile cords and the rubber casing in automobile tyres demonstrated that the only significant factor was the penetration of the fibre ends into the rubber. These fibre ends originated from the natural textile fibre (usually cotton), and it was their absence in synthetic fibres (e.g. nylon monofilament) that caused the difficulty in using these for this product. Any specific interaction between the rubber and the fibre was insignificant and only affected...

Fig. 15.3 Preparation of GnRHa implants and implantation of captive-reared bluefin tuna, (a) The two GnRHa implants (im) were attached to a polyethylene arrowhead (A) via a 0.5 mm nylon monofilament, followed by 10 mm reporter-spacer (sp), a 10-15 cm pink tag (tag), and a three colour individual identification code (cod), (b) In the second year experiment (2005), a modification was made to the implant assembly with the addition of a metal, conical leader (C) and disc stopper (D) around the implants (im), in order to prevent them from rubbing against the skin and muscle block of the fish during insertion, and being pushed over the tubing, (c) The arrowhead was fitted to a specially prepared spear and was administered to the fish using a spear gun. (d) The implant was administered at the posterior part of the tail (arrows) and the success of the implantation procedure was first evaluated by the diver, after visually examining if the reporter-spacer was inside the fish (Mylonas et at., 2007).
