Start a Spherical Nonwoven Swab Manufacturing


(170) Start a  Spherical Nonwoven Swab Manufacturing

The currently used cotton gauze pads are comprised of multiple layers of woven
fabric secured together in a rectangular or square shape (Figure 1). These pads are
used to wipe blood or other body fluids from incisions or wounds. An ideal surgical
swab should have higher absorbency, better wicking, high wet strength with a soft
feel and should provide easy swipe during surgery. In addition, the swab should
have low linting (fibre migration), non-toxic and should create low bio-medical
waste. The currently used woven gauze pads have following disadvantages:-
- lower absorbency, so multiple layers and larger dimensions (45X45, 30X30,
22.5X22.5 sq. cm) are used leading to higher bio-medical waste;
- not easy to fold edges of multiple layers of smaller dimensions (e.g. 5X5,
7.5X7.5 sq.cm) which may lead to infections due to edges;
- currently, smaller dimensions are being used by holding in a clipper scissor
folded in a spherical shape;
- larger dimensions (45X45, 30X30, 22.5X22.5 sq. cm) are being used for neuro,
ophthalmic or keyhole surgeries creating high level of bio-medical waste,
although smaller dimensions can be used for these surgeries.
A joint clinical and laboratory study conducted at East Glamorgan General Hospital,
UK and Surgical Material Testing Laboratory, UK has established that the nonwoven
swab has practical and economic advantages over traditional cotton gauze owing to
their ability to retain fluid and is manufactured using less expensive raw materials1.
It has also been demonstrated that the nonwoven swabs are more absorbent than
that of traditional cotton gauze both on a gram/gram basis and in terms of total
absorbency of the swabs. On comparison in terms of softness, conformability,
ability to pad or pack, resistance to snagging, shredding and ease of counting when
wet, the nonwoven swab is as effective as traditional gauze. Additionally, the
manufacturing of nonwoven swab is simpler than that of traditional gauze which
involves spinning, weaving and chemical processing. In terms of bio-medical waste,
nonwoven swabs generate a lesser amount of dump owing to higher absorbency
than that of traditional gauze.
        

Market Size and Competition
The initial findings suggest that there is a huge requirement of this newly developed
product in the operation theatres, for dental applications and by the medical staffs
involved in the management of wound, such as removing wound exudates, cleaning
or application of medicaments both in Indian and overseas market. Additionally,
owing to the low fibre migration, these products are also preferred in place of
cotton-balls for cosmetic applications. Currently, hand rolled solid ball of cotton and
woven cotton gauze pads are being used in the Indian market. Most of them are
manually manufactured and are usually prepared within the department from the
sterile cotton roll or using woven cotton fabric. There are local sterile cotton
converters who provide the cotton balls and woven plied gauze (usually manual).
As an estimate, over 20 million pieces (per month) are required for the domestic
market. Internationally, the feedback received from the company’s manufacturing
the ‘First-Aid Kits’, the requirement could be of 500 million pieces (per month) for
exports. Our competitors are suppliers of woven gauze pads. However, none of
these are supplying gauze pads in the spherical structure especially in the smaller
dimensions.
Manufacturing Systems for Nonwoven Swabs
High reliability and the automatic transfer of product piles into a packaging machine coupled to the manufacturing machine are distinguishing features of the GFM manufacturing systems for Nonwoven swabs.
