Microfibre Polyester.

Advancements in extrusion technology have reduced the achievable linear density of polyethylene terephthalate fiber to less that 1.0 dtex, resulting in a fineness comparable to natural silk. Worldwide production of polyester microfiber is approximately 80

Microfiber Fineness.

A literature survey of microfibers focuses on fiber fineness, the market potential for microfibers, the definition and limits of fiber fineness, and variations in the definitions of microfibers. As fiber companies produce increasingly finer microfibers, t

Process for dyeing melamine/formaldehyde condensation products

A general dyeing formulation for treating fibres, yarns, woven and knitted and nonwoven fabrics is presented. An aqueous dye bath at pH 1-12 is used at 20-250C and one or several dyes from the class comprising azo, anthraquinone, cumarin, methine, azomethine, quinophthalone or nitro dyes are employed. IPC D06P.

An Investigation Into the Scope of Total Recycling of Acrylic Fibre Dyeing Effluent Using an Adsorbent Column.

Researchers investigated the recovery of basic dyes from acrylic fiber dyeing effluents using an adsorbent column. The study included basic dye chemistry in the adsorbent, adsorption mechanisms, adsorption capacities of various basic dyes, and the effects of feed composition on adsorption. The data will be helpful for specifying the optim..

Recycled Cellulosic Fibers from Scrap Textiles.

Researchers used swatches of 50/50 cotton/polyester blend fabrics as examples of fully recyclable cellulosic textile scrap. Differential scanning calorimetry from the enthalpy of melting determined the polyethylene content. The study dissolved the cellulo

Improvements for Wool Textiles.

The quality of woolen fabrics has improved in recent years due to the development of new finishing methods by Kanebo, Nippon Keori Kaisha, and Daito Woolen Spinning and Weaving Company. The shrinkae properties of wool fibers depends on the response of sca

Development of Acrylate Based Superabsorbent Polymers - A Growing Speciality Commodity for Hygienic Application.

Chemical manufacturers are rapidly developing new superabsorbent polymers (SAPs) for hygienic products. A team of chemists in India recently investigated the synthesis and properties of acrylate based SAPs. They utilized the inverse suspension polymerizat

Opportunities for Energy Saving in the Texturing Process.

Two heater crimping machines offer energy savings during yarn manufacturing. The continuous drawtexturing process combines filament deformation and yarn fixing in one texturing zone. Energy consumption is influenced by the length of the heater, heater temperature, structure of insulating layer, air flow inside and outside of the heater, a..

땀과 수분에의 대응

인간은 신체의 열평형(열생산량과 열방산량과의 균형) 기능에 의해 체온이 일정하게 유지되도록 생리적으로 조절기능이 있고, 의복의 착용은 열생산량과 열방산량과의 균형을 유지하기 위한 중요한 역할로서 인간특유의 행동성 체온조절수단이라 할 수 있다. 신체의 열평형은 (열생산량)±(복사)±(전도와 대류)-(증발)=(축열량)으로 나타내며, 의복의 역할을 환경-의..

Production of mineral fibres

In this process a mineral charge containing briquettes is melted in a furnace to form a melt from which mineral fibres are spun. the briquettes are compression moulded and are bonded using an agent containing molasses, usually with lime. The briquettes may include vegetable or other fibres to improve green strength. IPC C03C C03B.
