Description
(1) technical field
The present invention relates to mensuration and the pre-treating method of a kind of terylene and other kind fibre compositions and content, specifically use silica sand as a solid masses spreading agent, utilize differential scanning calorimetry to measure the method containing blending composition in two component blend fabric of terylene and content.
(2) background technology
Blending chemical & blended fabric refers to that the natural fibers such as man-made fiber and other cottons, fiber crops, silk, hair mix the textile product that spins and be made into, and has in the market a lot of different types of blending products, and the fabric that wherein contains terylene chemical fibre accounts for the very great share in market.Natural fiber (as cotton fiber) Moisture Absorption Properties of Fabrics is good, is difficult for producing static, and soft-touch is affine, and permeability is good, stand wear and tear.But bafta elasticity is poor, easily fold, does not have thermoplastic property, and washing shrinkage is larger, and moisture-sensitive is gone mouldy.And man-made fiber has the shortcomings such as hydroscopicity is poor, airtight, easy balling-up as terylene, but its elasticity is strong, and intensity and wearing quality are better, well-pressed, not yielding.Therefore on market often by two kinds of composition blending, polyester cotton blending thing for example, this blending had not only been given prominence to the style of terylene but also had been had the strong point of bafta, in dry, wet situation, elasticity and wearing quality are all better, dimensionally stable, washing shrinkage is little, have tall and straight, be difficult for fold, easily wash, the feature of quick-drying.Hair polyester fabric refers to wool and the thread fabric of dacron blended yarn, is the most general a kind of in current blending woollens.
The different blending that form have accounted for a very large part in textile industry and trade.The qualitative and quantitative analysis of blending rate is all very important for spinstry person, trader and consumer.Now, to mixed fibre mainly adopt microscopic method, thermal analysis system is qualitative and chemical agent dissolves standard measure.Microscopic method is by the longitudinal profile of microscopic examination fiber and cross sectional shape, or coordinate dyeing etc. to identify, but the mixing uniformity of cotton fiber and polyster fibre and the fineness of fiber all have impact to result, and depend on observer to a certain extent, therefore the method result precision is lower.Heat analysis is under temperature programmed control condition, a kind of technology of the temperature variant funtcional relationship of measurement of species physicochemical property, mainly contain thermogravimetry (TG) and differential thermal analysis (DSC), the quantitative article of the method is less, and lacks the determination data of actual sample.Chemical dissolution method is to utilize the solubility property of various fibers in different chemical solvents to differentiate the method for fiber, but the whole operating process of the method is loaded down with trivial details, time-consuming, accuracy and data reappearance is low, healthy and surrounding environment influence is large to testing crew.
Develop a kind of easy, quick, containing two component fiber constituent in blended fabrics of terylene and the detection method of content, have great importance reliably.
