Effect of blend proportion on thermal behaviour of bamboo knitted fabrics

This study presents the thermal comfort properties of single jersey knitted fabric structures made from cotton, regenerated bamboo and cotton–bamboo blended yarns. Cotton, bamboo fibre and blends of the two fibres (100% cotton, 100% bamboo, 50:50 cotton:bamboo, 67:33 cotton:bamboo, 33:67 cotton:bamboo) were spun into yarns of identical linear density (20?tex). Each of the yarns so produced was converted to single jersey knitted fabrics with loose, medium and tight structures. The thermal conductivity of the fabrics was generally found to decrease with increase in the proportion of bamboo fibre. The relative water vapour permeability and air permeability of the fabrics were observed to increase with increase in bamboo fibre content. Statistical analysis also indicates that the results are significant for air permeability, thermal resistance, thermal conductivity and relative water vapour permeability of the fabrics.

Comfort properties of bamboo/cotton blended knitted fabrics produced from rotor spun yarns

The comfort characteristics of bamboo/cotton-blended knitted fabrics made from rotor-spun yarns were studied in this research work. Five different blend proportions namely 100% bamboo, 100% cotton, 50:50 cotton:bamboo, 70:30 cotton:bamboo and 30:70 cotton:bamboo were used to produce rotor-spun yarns of 30^sNe_c. The yarn samples developed out of these different blend proportions were evaluated for yarn strength and elongation, yarn unevenness, yarn imperfections and used to produce single-jersey-knitted fabrics. All the fabric samples were dyed and finished. Fabric samples were evaluated for geometrical properties such as course/inch, wales/inch, stitch density and thickness apart from measuring comfort properties such as airpermeability, thermal conductivity, thermal resistance and water vapour permeability. The results indicated that 50/50 bamboo/cotton-blended knits have comparable fabric quality in terms of comfort properties with respect to 100% bamboo fabrics.     

Comparative study of copper ion complex bamboo pulp and cotton knitted fabrics. Part II: wearability and durability

Apart from the antibacterial performance, wearability and durability are also important factors for the textile product quality. The paper mainly discusses the wearability and durability of bamboo pulp and cotton-knitted fabrics which were treated with alkali and copper ammonia solution. Washing fastness, release properties of copper ions when washing, bursting properties, abrasion resistance, permeability, moisture penetrability, and warmth retention properties of fabrics were tested to investigate the change after copper ammonia solution treatment. The results showed that although the release quantity of bamboo pulp fabrics was higher, the washing fastness of bamboo pulp fabrics was better than that of cotton fabrics. After 90 times’ washing, the copper ion complex fabrics still had good antibacterial performance. For both cotton and bamboo pulp fabrics, properties of the bursting strength, moisture penetrability and warmth retention had been improved, whereas properties of abrasion resistance and air permeability had receded.

It was observed that as the bamboo content increased, the wetting time decreased, maximum wetted radius decreased, rate of absorption increased, spreading speed decreased and OMMC decreased.
