19 07 2001Known methods to make polypropylene wettable involves surface grafting of acrylic acid by ultraviolet radiation or by other surface modification methods such as plasma which are slow and expensive [0099] For fibrous battery separator applications the polypropylene needs to be resistant to the KOH and exhibit permanent wettability throughout the life of the product
Polypropylene (PP) also known as polypropene is a thermoplastic polymer used in a wide variety of applications It is produced via chain-growth polymerization from the monomer propylene Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar Its properties are similar to polyethylene but it is slightly harder and more heat resistant
Openair Plasma surface modification technologies can achieve plastic activation at the highest level It is not unusual to reach surface tensions of more than 72 mN/m Extremely long-lasting plasma activation increases storage life and facilitates subsequent processing up to 12 months later
A plane surface of pure polypropylene has a contact angle with water (wetting angle) of approximately 90-100 This contact angle which is in the grey zone between hydrophilicity and hydrophobicity is reflected in the mediocre water repellent properties of nonwoven webs of polypropylene fibres Generally two major types of hydrophobicity are distinguished for textile materials The first
The surface modification of polypropylene non-woven fabric(NWF) by PVA The hydrophilic modification of polypropylene non-woven fabric (NWF) surface was conducted by coating PVA (poly vinyl alcohol) film on the NWF surface via dip-coating method (PVA) 。 2) polypropylene fabric

properties for nonwovens By Ellen Wuagneux Associate Editor Now more than ever fiber finishes play a key role in advancing the performance of nonwovens Finishes help modify the surface characteristics of fabrics allowing designers to engineer the specific performance they need As fabrics are called on to do more at ever-lower prices and weights the need for fabric surface modification is
Modification of the wetting behavior of hydrophobic surfaces is essential in a variety of materials including textiles and membranes that require control of fluid interactions adhesion transport processes sensing etc This investigation examines the enhancement of wettability of animportant class of textile materials viz polypropylene (PP) fibers by surface adsorption of different
FAST AND EFFICIENT SURF ACE TREA TMENT FOR NONWOVEN MA TERIALS BY ATMOSPHERIC PRESSURE PLASMA according to the studies of Kwon et al [12] surface modification of polypropylene film by atmospheric pressure plasma is more lucrative in a relatively short plasma treatment time Plasma treatments are used to modify surface properties but it is also
Surface Modification of Fibers and Nonwovens with Melt Additives: Author: Datla Vasantha Madhuri: Advisors: Dr Alan Tonelli Committee Member Dr Behnam Pourdeyhimi Committee Chair Dr Eunkyoung Shim Committee Co-Chair Dr Keith Beck Committee Member Dr Jan Genzer Committee Member: Abstract: Polypropylene (PP) fibers widely utilized in woven and nonwoven industry have highly inert
Development of a method which is able to measure surface and bulk crystallinity of Polypropylene which is capable of measuring surface and bulk crystallinity of fibers in a non-destructive location-sensitive and fast way Surface and bulk crystallinity of fibers and nonwovens produced under different processing conditions is determined Influence of the calendaring process on bonding points
The surface property of the PP nonwoven fabrics before and after modification was determined through contact angle goniometry by using a DSA20 contact angle measurement device (Krss Germany) at room temperature and ambient humidity Deionized water was used as the corresponding liquid a liquid droplet (5 μl) was dripped onto the sample surface and at least five different positions were
Nonwoven webs in accordance with the present invention include multicomponent fibers bonded by a multiplicity of bond sites to form a coherent web The multicomponent fibers include a first component formed of a hydrophobic polypropylene and a second component formed of a blend of a hydrophobic polyolefin and a hydrophilic melt additive This second component is disposed at the surface of the

LOW-COST MANUFACTURING OF BATTERY SEPARATORS ON THE BASE OF POLYPROPYLENE NONWOVEN FABRICS Ľ Known surface modification techniques are for example surface treatment of resin fibers with a surfactant sulfonation and fluorination Of particular concern and commercial success is the surface modification of using UV graft copolymerization by acrylic acid
NatureWorks LLC has selected U S Pacific Nonwovens Industry Ltd as the exclusive agent for Ingeo™ spun-melt (spun-bond and melt-blown) nonwovens in the Asia Pacific Region The new relationship between NatureWorks the manufacturer of Ingeo biopolymer made from plants not oil and U S Pacific was announced in April at the international biopolymers conference "Innovation Tongweis
In this work linear isotactic polypropylene (L-PP) and long-chain branched polypropylene (LCB-PP) miscible blend both having comparable weight average molecular weight zero-shear viscosity and polydispersity index were used to produce nonwovens via melt blown technology in order to understand the role of long chain branching in the fiber diameter distribution
