8～14μm红外线对织物作用的测量

采用红外光谱辐射计和样品炉，测试了8～14μm波段涤、棉两种织物的红外线透过率，以及不同纺织材料和涂层织物的发射率．结果表明，透过率分别随着织物紧度和厚度的增加而减小，在厚度相差不大时，透过率与面密度呈负线性关系；对于非常紧密的织物，红外线透过率也不为零；纱线毛羽对红外线透过率影响较大．不同织物发射率大小的顺序：锦纶织物〉涤纶织物〉毛织物〉棉织物〉化学镀金属织物；混纺织物的发射率由组成该织物纤维材料的发射率决定；涂层织物的发射率主要受涂层剂的影响；对于相同材料的织物，颜色对发射率影响很小。

Mechanical Design and Research on Process of Air Suction Drawing System of Spunbonded Nonwoven

The design guideline for the air suction drawing system with auxiliary air was analyzed, a spunbonding nonwoven system named PADHL1 - 3200 was designed and polypropylene （PP） spunbonded nonwoven fabrics with excellent properties were achieved after many trial runs. On the other hand, the suction air velocity （VA） was calculated and the influence of VA on the bonding strengh of PP nonwoven fabrics was Studied as well. It was found that VA is 1.5 - 2.5 times of the spinning velocity. With the increase of VA, PP fibers become finer and the bonding strength of PP nonwoven fabrics increases as well.     

An Empirical Formula for Sound Absorption of Fibrous Materials

The sound absorption coefficient （SAC） curves of the nonwovens, fabrics, and thick fibrous layers with the frequency in the range of 125 - 3 200 Hz and cavity distances of 5 cm, 10 cm, 20 cm, 30 cm and 40 cm were measured. Based on analysis, it is found that the SAC is actually in direct proportion to the relative vibration amplitude of the sound wave, resulting in obtaining a mathematical expression showing that the SAC changes with the frequency for a given material. Additionally, a good corresponding relation between the maximal SAC and the permeability of the materials is discovered, thus an empirical formula is established. As a result, a complete SAC formula has been developed. In this formula, the SAC is solely a function of the sound wave frequency and permeability of the material. In comparison with sound absorption spectra of several materials, the calculated results and results measured with the formula coincide well with each other.

IN RELATION TO CLOTHING COMFORT DYNAMIC MOISTURE TRANSFER THROUGH FABRICS

A sweating apparatus has been developed to permit simultaneous measurement for fabric temperature change and relative humidity change at outer still air layer of fabrics. In this paper, we compared the temperature and relative humidity changes for silk fabrics with polyester fabrics and got GM(1,P) relation models respectively between maximum fabric temperature change, maximum relative humidity change at outer still air layer and relative fabric character parameters. Furthermore, by comparing the objective experiments with subjective wear trials, it is found that the amounts of the change rate of fabric temperature and relative humidity at outer still layer are the most important factors which influence clothing comfort in dynamic moisture transfer condition. The more the changes of temperature and R.H., the more the mugginess and the thermal sensation.

Analysis of the Appearance Diameter of Yarns in Worsted Fabrics

Three-dimensional Rotational Microscopy was used to take the photos of the fabrics. Three categories of yarn appearance diameters in the worsted fabrics were discussed. The fabrics were grouped into two to explore the relationships between yam appearance diameters at the interlacing points, opening points, and the calculated yam diameters. The correlations between the appearance diameters and fabric parameters were given, and the results showed that the calculated yam diameter and warp cover factor had a very big influence on yam appearance diameter. The equations expressing the relationship between yam appearance diameters and fabric parameters are established using step-regression method. The validation of the equations for one type of fabrics shows a good accuracy with the average error below 9% except the weft fdaments exceeding 22%.
