Air permeability of the non-woven fabrics is important property which indicates the thermal insulation characteristic of the fabrics. Air permeability of the fabric is an important fabric property which measures the rate of air flow through a fabric under differential pressure conditions. It decides the thermal insulation properties of the needle punched non-woven fabric. These properties are tested for the non-woven fabric used in this study and reported. The effect of areal density, porosity and thickness of different blend composition of sisal and polypropylene needle punched non-woven fabrics are thoroughly investigated in this paper.

In the last decades, Nonlinear partial differential equations (NPDEs) have become es- sential tools to model complex phenomena that arise in different aspects of science and engineering such as hydrodynamics. Therefore, constructing exact and approximate so- lutions of NLPDEs is of great importance in mathematical sciences. Previously authors have done similar work with restriction of K and L to be one. In this paper we solve the generalized Boussinesq coupled equations: ut + Kvx + Luux = 0; K > 0, L > 0 vt + uvx + uxxx = 0 using Lie symmetry of differential equations where u = u(x, t) is the velocity of water and v = v(x, t) the total depth of water and subscripts denote partial derivatives. The positive constants K,L would enable further analysis of optimal water depth and velocity be determined.

A research attempt at obtaining aromatherapic textiles which we carried out is presented, together with the broad background of research into aromachology investigation. We developed aromatherapic textiles using the fragrance with ?-cyclodextrin inclusion compounds. The sedative effects for emotion and the pharmaceutical effects of essential oils are presented in detail, on the basis of the achievements of aromachology and aromatherapy. Research shows that the effects of fragrance on humans are based on a great deal of medical experience. ?-cyclodextrin was chosen for the aromatherapic textile as host molecule, because it exhibits qualities which are beneficial for the human body. ?-cyclodextrins molecules are capable of forming inclusion compounds with fragrances that fit into the coneshaped hydrophobic cavity. As a result, the release-fragrance rates are greatly decreased. The fragrance inclusion compounds are fixed onto cotton with a low temperature binder by the conventional pad-thermofixed method. The fragrance-release rates are related to the nature of the fragrance oils themselves. The results of sensorial evaluations show that the perfume of fabric is sensed for over 30 days. An aromatherapic textile could be achieved by means of the fragrance with ?-cyclodextrin inclusion compounds in this way.

Differential Scanning Calorimetry (DSC), Wide Angle X-ray Diffraction (WAXRD), Fourier Transform Infra-Red Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) have been used to study the thermal characteristics, crystallinity index, reactivity and surface morphology of untreated and chemically modified fibres. The technical textiles deals with the chemical composition, morphological fibre characteristics, physical plant characteristics and mechanical properties of various types of natural fibres. In this paper SEM (Scanning Electron Microscopy) analysis of untreated and treated sisal fibres has been investigated.
