Fiber Structure - an overview | ScienceDirect Topics
网页A fiber structure (X, p, b) is called a fiber space (or fibration) for the class A if for each Y in A, each continuous map f:Y × {0} → X, and each homotopy ϕ: Y × I → B of p ∘ f, there exists a homotopy φ ˜ of f covering ϕ.
Fiber - Wikipedia
网页Fibers can be divided into natural and artificial (synthetic) substance, their properties can affect their performance in many applications. Synthetic fiber materials are increasingly replacing other conventional materials like glass and wood in a number of applications. [11]
Fibers - Chemistry Encyclopedia - structure, water, proteins, …
网页Fibers are long strands of molecules interwoven to form a linear, stringlike structure. They may be natural or made by humans and are essential to A portion of a cellulose fiber.
Fiber - The Nutrition Source
网页The National Academy of Medicine defines fiber as: 1) dietary fibers (nondigestible carbohydrates and lignans) that occur naturally in plants, and 2) functional fibers that are extracted from plants or synthetically made and are nondigestible with a beneficial health effect in humans. [1]
Internal Structure of Fibers - SpringerLink
网页2023年1月10日 · This chapter deals with the internal structure of synthetic and cellulosic fibers. It differs fundamentally from the structure of inorganic fibers (e.g. glass) and metal fibers. Their structures are considered separately in the corresponding chapters.
Chemical composition and molecular structure - Encyclopedia Britannica
网页The linear, branched, and network architectures are represented (from top), respectively, by high-density polyethylene (HDPE), low-density polyethylene (LDPE), and phenol formaldehyde (PF). The chemical structure and molecular structure of highlighted regions are also shown.
Introduction to the science of fibers - ScienceDirect
网页2018年1月1日 · The science of fibers is multidisciplinary as it encompasses botany, zoology, organic chemistry, the physics of materials, and all of material science from polymers to ceramics. Fibers are ubiquitous and can be found all around us, not only in clothes but also in our very makeup.
Introduction: The structure of fibres | SpringerLink
网页The specific chemistry of a given type of fibre is undeniably crucial in determining many features associated with its processing, performance and end-uses; but it may also be asserted that its physical structure — i.e. the organisation and geometrical...
Fibre structure: its formation and relation to performance
网页2009年1月1日 · The slow growth of natural fibres under genetic control gives different structures from the fast routes of industrial production. Differences within each group, for example between cotton, wool and silk or between melt and solution spinning, lead to a variety of structures.
History of Fiber Structure - SpringerLink
网页2016年8月17日 · In the first section we describe the research history of structure of natural fibers, especially natural cellulose fiber, starting from a micelle model to a fringed-micelle model. In the second section, we focus on the history of the structural study of synthetic fibers from fringed-micelle microfibril model to shish-kebab model.
