Abstract

A method of piercing spun yarn and a knitting including the piercing of spun yarn. In the method capable of increasing quality and aesthetic appearance by eliminating the formation of knots in piercing spun yarn and the mixing of colors and the projection of end yarn, the tip sides (11a) and (12a) of two pieces of spun yarn (11) and (12) are folded in ''J'' shape, and opposed to each other so that folded parts (11b) and (12b) can be bound to each other. The tip sides (11a) and (12a) are twined with the base end sides (11c) and (12c) of the folded parts (11b) and (12b) and joined to each other. The tip sides (11a) and (12a) of the spun yarn (11) and (12) are twined with the base end sides (11c) and (12c) of the folded parts (11b) and (12b) and connected to each other. Since the twining is performed within the spun yarn (11) and (12), piercing can be securely performed irrespective of the type of a mating material. Since the knot is not formed, in knitting, the possibility of occurrence of yarn breakage by resistance in forming stitches or hooking to a knitting needle can be eliminated. Since the two pieces of yarn are bound to each other at the folded parts (11b) and (12b), the quality and the aesthetic appearance can be increased without causing the mixing of colors even if the colors of the yarns are different from each other.

Description

The jointing method of yarn and the knitted fabric that comprises joint

Technical field

The present invention relates to make the jointing method of the yarn that the fine fibre boundling forms and the knitted fabric that comprises joint by spinning.

Background technology

In the past, be extensive use of stocking yarn or the yarn for weaving purpose that natural fiber or syntheticfibres etc. are spinned and obtain as material in order to form knitted fabric or woven fabric.These stocking yarns or yarn for weaving purpose may be cut off in braiding or in weaving on the way, need the joint that is used to repair thus.And, under situation, also cooperate the moment of changing decorative pattern to carry out the joint (for example opening flat 6-2250 communique) of different relatively stocking yarns with reference to the spy with the stocking yarn making knit fabric.Also disclose when knitted glove, the stocking yarn different with color carries out joint, thereby carries out the technical scheme (for example opening the 2004-149941 communique with reference to the spy) of style braiding.

Fig. 4 is as the conventional method of existing joint, and expression forms tieing and connects the end state each other of different yarns.That is, yarn 1 and yarn 2 form tieing 3 in the end and carry out joint.Front end 1a, the 2a of each

yarn

1,2 is outstanding from tieing 3.Though

front end

1a, 2a can be difficult to make its complete obiteration forming tieing 3 back cut-outs and shortening.Be under the situation of stocking yarn of making knit fabric at

yarn

1,2, use knotting device in order to form tieing 3.And, form tieing 3 and carry out the bonded assembly method and not only can be used for yarn, can also be widely used in rope etc.

Fig. 5 represents by not forming the engagement state that tieing carries out the

method joint yarn

1,2 of joint.This jointing method at

yarn

1,2 be under the situation of yarn effectively, the sth. made by twisting of the front fiber of 2 relative one

threads

1,2 is temporarily untied the back and is twined mutually, forms the joint 4 that outward appearance is " I " font.In addition, front end 1a, the 2a of each

yarn

1,2 are more residual under the state of backtwisting.Can carry out rapidly based on the joint that forms this joint 4 (for example with reference to special public clear 60-39767 communique) by modes such as ejection pressurized airs.

Fig. 6 represents not form tieing and the other method of carrying out joint.This method is that the situation of yarn is effective to yarn 1,2 also.Yarn 1,2 makes front end towards equidirectional and side by side, front end is twined each other and forms envelope portion 5 (for example opening the 2004-27463 communique with reference to the spy).By the envelope portion 5 that this method forms, be " T " font in appearance, be equivalent to the part of the ordinate of " T " word, outstanding to the radial outside of the part of the horizontal line of " T " word that is equivalent to form by yarn 1,2.Front end in this envelope portion 5, front end 1a, the 2a of

yarn

1,2 is outstanding with the state of backtwisting.Open the spy and also to use this jointing method in the 2004-149941 communique.

In the time of will being applied on the stocking yarn with the joint of formation such as knotting device tieing 3 as shown in Figure 4, because the diameter of tieing 3, thereby might when forming coil, become resistance, or hang over and cause broken yarn on the knitting needle with several times degree of

yarn

1,2 thicknesses.Twine and in the joint 4 that forms, the color of

yarn

1,2 does not produce colour mixture simultaneously at as shown in Figure 52 one

threads

1,2, it is unintelligible that color boundaries becomes.Under the situation of braiding style, when producing colour mixture, can produce undesired color part, thereby destroy the outward appearance of knitted fabric at joint 4 places of the

yarn

1,2 that has engaged different colours.In the method for as shown in Figure 6 the front end twisted that makes 2 one

threads

1,2, the problem that is treated as of envelope portion 5.Envelope portion 5 is outstanding and when visible, can disfeature to the outside of knitted fabric.Enroll in envelope portion 5 under the situation of knitted fabric, produce the part of the coenvelope portion 5 that adds, 3 amounts of stocking yarn formation.If envelope portion 5 can be taken in the inside of knitted fabric and hide, then change in mode that can not colour mixture by envelope portion 5 bonded

assembly yarns

1,2, can weave the good style of outward appearance etc.But, be difficult to handle well envelope portion 5.And, in Fig. 5 and method shown in Figure 6, owing to twine

different yarns

1,2, thereby during the different in kind of

yarn

1,2, need to consider combination sometimes.
