Cooling woven technical fabrics after heat treatment

Textile roll goods leave heat treatment machines (heat-setting machines, dryers) with residual heat retained in the batched fabric. Its hitherto unknown effect has been examined in practical mill trials. Depending on the residual heat the batching temperature can reach 60。. During gradual cooling, which lasts for days, big temperature di..

A study on relation between air permeability and cover-factor of fabrics (Chinese)

The relationship between air permeability and pressure difference between fabrics is measured. Six fabrics which have same yarn linear density, threads per 10 cm and different picks per cosity and inertia of air flow exists. The regression equations were calculated for △P=＞au + bu , with the correlation coefficient greater than 0.98. Th..

Consumer assessment and comparison of physical characteristics of cotton-wool blend fabrics

This study compared physical characteristies in four fabrics before and after a wear trial. The constructed fabrics were: 100％ pima cotton, 90-100％ pima cotton/wool, 80-20％ pima cotton/wool, and 70-30％ pima cotton/wool. The physical properties of breaking strength, stiffness, tear resistance, pilling resistance, and wrinkle recovery w..
