Abstract
ABSTRACT OF DISCLOSURE
This invention relates to processing the edge of the knitted articles like gloves, sweaters etc. Staple-fibers are twisted around heat-shrinkable filament to form core-spun yarn and the core-spun yarn is untwisted in the opposite direction. The core-spun yarn made thick by twisting is covered with heat-adhesive filament. The heat-adhesive filament is melted and the heat-shrinkable filament is heated enough to shrink without melting.
Middle staple-fibers of the darning-thread manufactured through this process will not be hard, therefore, the knitted articles manufactured through this process give the user comfortable feeling when putting on or off the knitted articles and there are few, if any, cases to abrase his skin.

Description
This invention relates to the process of manufacturing darning-thread which prevents the edges of the knitted articles such as gloves, sweaters etc. from ravelling.
Fig. 1 is a diagram of the structure of the darning-thread of thi~ invention.
Fig. 2 is a cross-sectional view of the structure o~ the darning-thread of the invention.
Fig. 3 is a diagram of the structure of the darning-thread of the prior art.
Structurally, after knitting, the ends o~ the knitted ;~
articles require treatment to be prevented from ravelling.
As shown in Fig. 3, there is an existing process of ~ -manufacturing darning-thread comprising: heat-shrinkable filament "a", staple-fibres "b" which protects filament "a"
and filament "c" which is heated to be melted and adhered at the same time.
In the existing processes of manufacturing the darning-; thread, heating the filament "c", after knitting, to melt and adhere at the same time, prevents the edges of the knitted articles from ravelling.
But in the prior art, the staple-fibers used as the --middle of the darning-thread are twisted.
Therefore, the adhered spots will be hard and left in -~
the outmost part of the darning-thread and also permeates ~ -~
into the middle staple-fibers "b", which causes whole thread to be hard. This part touches user's skin every time he puts ~ -on or off his knitted articles. - -Taking gloves for example, gloves manufactured through ~ ~-such existing process give the user uncomfortable feeling, because the hard part touches his wrist continually while working, or even the user becomes intolerable to wear for his -skin being abrased. ;

Fig. 2 is a cross-sectional view of the structure o~ the darning-thread of the invention.
Fig. 3 is a diagram of the structure of the darning-thread of the prior art.
Structurally, after knitting, the ends o~ the knitted ;~
articles require treatment to be prevented from ravelling.
As shown in Fig. 3, there is an existing process of ~ -manufacturing darning-thread comprising: heat-shrinkable filament "a", staple-fibres "b" which protects filament "a"
and filament "c" which is heated to be melted and adhered at the same time.
In the existing processes of manufacturing the darning-; thread, heating the filament "c", after knitting, to melt and adhere at the same time, prevents the edges of the knitted articles from ravelling.
But in the prior art, the staple-fibers used as the --middle of the darning-thread are twisted.
Therefore, the adhered spots will be hard and left in -~
the outmost part of the darning-thread and also permeates ~ -~
into the middle staple-fibers "b", which causes whole thread to be hard. This part touches user's skin every time he puts ~ -on or off his knitted articles. - -Taking gloves for example, gloves manufactured through ~ ~-such existing process give the user uncomfortable feeling, because the hard part touches his wrist continually while working, or even the user becomes intolerable to wear for his -skin being abrased. ;
~ ~'~' ' This same may be said to the other knitted articles ~uch as sweaters.
This invention provides the process of manufacturing the darning-thread which improves the inconvenient points mentioned above. Middle staple-fibers of the darning-thread manufactured through this process will not be hard even after heated to be melted and adhered, therefore, the edge of the knitted articles such as gloves, sweaters, etc. manufactured through this process give the user comfortable feeling when putting on or off the knitted articles and there are few, if any, cases to abrase his skin.
In this invention, staple-fibers are twined around heat- ~
shrinkable filament to form a core-spun yarn and the core- ~ ~ ;
spun yarn is untwisted in the opposite direction. A heat-adhesive filament is covered the untwisted core-spun yarn `~
made thick by untwisting. The heat-adhesive filament is melted and heat-shrinkable filament is heated enough to shrink without melting. Middle-staple fibers of the darning- '-thread manufactured through this process will not be hard, ;-`~
therefore, the edge of the knitted articles such as gloves, -~
sweaters, etc. manufactured through this process give the `
user comfortable feeling when putting on or off the knitted `~
articles and there are few, if any, cases to abrase his skin.

Referring now to the construction of the embodiment of the darning-thread of this invention.
A) Construction of darning-thread The darning-thread of this invention is composed of the untwisted core-spun yarn 1 and the heat-adhesive filament Z
covering the untwisted core-spun yarn 1.
B) Core-spun yarn The core-spun yarn 1 is a material of common knowledge.
For instance, the core-spun yarn 1 is composed of heat-shrinkable filament 11 such as a spandex filament used as acore and staple-fibers 12 covering the core filament.
