Pilling is one of the fabric faults that originally found in knitted woolen goods especially made from soft twisted yarns. The rubbing action on loose fibres that is present on the fabric surface gives a high tendency to form pills which gives poor appearance to the fabric. This study was carried out to investigate the effect of repeated launderings on the propensity of pilling formation by using pill grade machine. The primary objective of this study was to determine the pilling behaviour of different types of weft knitted fabrics after a repeated number of laundering cycles. The study was conducted using two types of knitted fabrics; cotton and polyester with three types of knitted structures; interlock, 1x1 rib and plain jersey. The various number of laundering cycles were given on the fabrics and followed by 15,000 revolutions of ICI pilling box. The results showed that polyester fibre has better pilling resistance due to its exceptional strength, whilst in terms of fabric structure, plain jersey showed an excellent resistance. This is due to the higher density and compact structure that it possessed.
The Silver Reed Model LK150 knitting machine is a home knitting machine which is
extremely lightweight and compact, making it preferable by most home knitters.
There are various knitwears with interesting patterns can be made using this model. In
the field of garments manufacturing by using flatbed knitting machines, it is
important to understand the physical properties of fabric so that their impact on
dimensional changes can be predicted to produce the most suitable end use. The
samples were produced by using a blended bamboo/cotton yarn, with a composition
of 30% cotton and 70% bamboo. The main objectives of this study are to to evaluate
the physical properties of single jersey fabric knitted on home knitting machine by
using different stitch dials and to relate the physical properties with different stitch
lengths. Then, all tests were conducted to compare the physical properties of samples
between three different stitch dials and the effects of before and after washing. The
physical properties measured in this research were stitch length, stitch density, weight,
thickness, absorbency and shrinkage. The result indicated that the longer the stitch
length, the higher the percentage of the water impact penetration. Meanwhile, there
was a slight reduction on the density, thickness and fabric weight. In addition, the
result after three times washing showed that the samples only had slight changes in
density, thickness, weight and stitch length, but has significant changes on the water
impact penetration.
This study was carried out to determine the hand properties of cotton woven fabric treated with three different brands of commercial softeners and to identify the stiffness relationship between objective and subjective assessment. The hand properties refer to the impression feels when the fabric is touched, squeezed, rubbed or otherwise handled. The cotton woven fabric was categorized into light to medium weight and medium to heavy weight type. Three different brands of softener; Brand A, Brand B and Brand C were used, and the fabric samples were washed by using top load home washing machine for 48 minutes in each cycle with the detergent and softener added into the washing machine dispenser drawer following the instruction label on the softener’s bottle. After washing process was done, the samples were evaluated objectively by their stiffness and panel experts did subjective assessment on the samples by investigating three attributes namely stiffness, softness, smoothness. The results obtained from objective and subjective evaluation were then analysed using Two-way ANOVA and Kruskal Wallis test respectively.
