“…2 is summarised in Table 4. The results exhibited very good ratings (4)(5). Although the ratings of colour fastness to perspiration using an octadecyl derivative were particularly good, when the colour strength was taken into account ( Figure 8) the fastness performance of the octadecyl derivative was not so different from the fastness performance of the other derivatives used.…”

“…The colour strength (expressed as the K ⁄ S value) of the dyed fabrics was estimated from the spectral diffuse reflectance at the wavelength of maximum absorption (k max = 600 nm). It was calculated using the Kubelka-Munk equation (Eqn 1) [53]: (3), delivery pump (6; consisting of cooler [4] and high-pressure pump [5]), safety valve (8), pressure gauge (9), magnetic stirring constant-temperature air bath (19; consisting of pre-heater [11], dyeing vessel [12], filter [16], magnetic stirrer [17] and constant-temperature air bath [18]), temperature gauge (20), semi-automatic back pressure regulating valve (24; consisting of back pressure regulating valve [22] and heater [23]). A stirring bar (15), PP fabric #1 (14) and sandwiched dyestuff (13) were put into the dyeing vessel (12) in sequence (3), high-pressure pump (4), pre-heater (5), pressure gauges (6)(7)(8), magnetic drive (9), DC motor (10), safety valves (11,12), cooler (13), stop valves (14-18), needle valve (19) and heater (20)…”

A series of 1,4‐bis(alkylamino)anthraquinone dyestuffs were applied for supercritical fluid dyeing of unmodified polypropylene fabric, which is known to be difficult to dye in a conventional aqueous system. A marked tendency was shown that the dyeability improved as the carbon number of alkyl substituents on the anthraquinone chromophore increased. By evaluating the build‐up curves of the dyestuff, it was found that the carbon number of optimum alkyl chain length for 1,4‐bis(alkylamino)anthraquinone was 8–12. From the relationship between the build‐up curve and the colour fastness, it was concluded that the upper limit of dyeing depth for good colour fastness was 40 mmol/kg of fibre.

Polypropylene (PP) is modified utilizing a poly(ester amide)‐based hyperbranched polymer (PS). A maleic‐modified PP is used to enhance the compatibility. Usual tensile experiments are carried out. The nanocrystalline structure is studied using small‐angle X‐ray scattering (SAXS) while a uniaxial mechanical load is simultaneously applied. SAXS patterns are analysed using procedures written in PV‐WAVE. The chord distribution function (CDF) is calculated and nanostructural parameters such as long period (lp) and nanodeformation (ϵNano) are extracted. The correlations between macromechanical parameters and nanostructures are studied. Mechanical results show that PS has a plasticizing effect. Reactively blended samples demonstrate enhanced mechanical properties. SAXS patterns reveal a well‐known structure of PP as a peculiar architecture of the nanostructure. Crystalline branching occurs in a geometry that is known as a mother–daughter crystal lamellar structure, also called a crosshatching structure. It is concluded that adding PS distorts the stacking of crystalline domains. The structural information from SAXS patterns in reciprocal space is visualized in real space in the calculated CDFs. The CDFs indicate that in simple blends, lp of the crystalline stacks increases compared to blank PP. Nevertheless, reactively blended samples show an increase of lp compared to blank PP; however, they possess smaller lp compared to simple blends. © 2012 Society of Chemical Industry

“…Two important factors, namely the basicity of the amine's nitrogen and the required amount of such amine nitrogen should be considered for improving acid dye‐ability of polypropylene. The more basic the nitrogen, the lesser would be the required amount of the amine modifier in the PP matrix 9. Akrman et al9–12 have synthesized two amine polymeric additives with molecular mass of 4500 and 4300 (g/mol) and basic nitrogen content of 3.7 and 4.9%, so that after blending with polypropylene improved dye‐ability with acid dyes could be encountered.…”

Polypropylene is utilized in manifold applications due to its unique properties. However, its use has been limited in the textile industry because conventional dyestuffs have no affinity for this polymer. Amine modifiers, generally improve the dye-ability of polypropylene. Polyamide 6 (PA6) is a traditional amine modifier which improves the dyeing ability of polypropylene with disperse dyes. In this investigation, polyetheramine (PEA) is introduced as a novel amine modifier which improves the dye-ability of polypropylene with disperse and acid dyestuffs. To this end, the dyeing behavior as well as possible impairments of tensile properties of PEA modified polypropylene were studied and compared to PA6 modified polypropylene. As with the PA6 containing blends, the tensile properties of the incompatible PP/PEA blends decreased due to weak interfacial adhesions between the components of the blends. However, the incorporation of a compatibilizer into such blends led to better dispersions of modifiers in the matrix as well as formation of amide or imide linkages which in turn reincreased the tensile properties almost to their initial values. Both PEA and PA6 modifiers improved the disperse dye uptake of the blends. However, Only Jeffamine ED-2003 (i.e., PEA) was capable of enhance the acid dye uptake of modified polypropylene.
