Abstract

Elastic textile goods are manufd. from natural fibers, such as silk fibrin, protein fiber, fibrin fiber (silk, wool, cotton), or their mixt. Natural fiber-contg. filaments are used to strongly fix unidirectional twists and solve the twists to the opposite direction (right or left) until twisting is begun or they return to the original direction from the reversed twisted state. Above filaments are combined, in textile goods, for their returning power to be supported by adjacent filaments.

Description

Stretch fabric made of natural fibers

FIG. 1 is a schematic diagram of a weft elastically twisted weft and a fabric which is usually woven by a warp that is not elastic.

2 is a schematic diagram of a yarn that can be used as at least one of a warp or weft yarn or a weft yarn according to the present invention, in which a plurality of rotational return forces are opposed to each other.

3 is a schematic cross-sectional view of a knitted fabric such as stockings as another embodiment of the present invention.

The present invention relates to an elastic fiber product made of natural fibers. The method for producing this kind of high-elastic fiber products by synthetic materials is well known, in which case the fiber products are made of elastic materials and / or yarns made of high elasticity, in particular polyamide yarns to which the desired elasticity is added by manufacture. .

This kind of high elastic fiber products (elastic fiber products), in particular knitted fabrics for welfare fabrics, stockings, shirts, etc., are effective in the welfare performance of the welfare determined by the elasticity, which is obtained by the above materials. . That is, the material not only wrinkles when sitting, but also wrinkles when worn, and does not become fat when worn. In particular, high-elastic fiber products are meaningful to simplify the manufacturing and processing by greatly reducing the amount of fibers required by conventional low-stretch products.

However, textile products made of synthetic yarns are not worn by a wide range of people, and have the disadvantage of being relatively poor in disadvantageous properties, in particular heat retention and hygroscopicity. It is also known to manufacture polyamide yarn and wool or cotton with blended fiber products such as blends. The product itself can also be made from synthetic and natural fibers.

The elasticity of this kind of blended yarn or blended product is limited by the least stretchable part (in this case natural fiber), and there is a limit to the stretch and elasticity of the fiber products made from such materials. In addition, such a fiber product always contains a relatively high proportion of synthetic fibers, and the higher the ratio, the higher the elasticity of the fiber product, so that the defects of the synthetic fibers are partially alleviated by the incorporation of natural fibers.

In panties, stockings or undergarments there is a problem that this knit fabric must have sufficient elasticity in any direction. In such a case, the elasticity of the longitudinal direction is necessary to obtain not only the transverse elasticity obtained as a suitable knitting structure but also an essential structure. In the stockings, the knitting itself is opposed to the socks, in which the elasticity in the longitudinal direction is averaged by means of fastening means having a considerable elasticity, for example, straps, etc. Elasticity of the longitudinal direction is essential. For this reason, in the past, the manufacture of socks made of natural dogs was possible, but the manufacture of stockings and such knitted fabrics was impossible because of the lack of essential longitudinal stretch.

The large elasticity required in any direction is required to impart very large elasticity to the individual long fibers in the knitted fabric, although it is not sufficiently obtained by the elasticity of the conventional knitted fabric mainly occurring in the transverse direction. In the past, such high-elastic fiber products were made only of synthetic fibers. It is also known to process inelastic natural fibers together with highly elastic fibers to ensure elasticity in many directions. In this case, the synthetic fibers may be fibers of elastic material such as polyamide or polyurethane manufactured. However, what determines elasticity is always the ratio of synthetic fibers. However, synthetic fibers do not have good performance as described above. Therefore, wearing such stockings or underwear made of synthetic fibers clings to the skin with its low hygroscopicity in summer, but only a little warmth in winter. In addition, as is clear from the above description, many people feel a resistance to wearing synthetic fibers.

The only known high-elastic yarn made from natural fibers (West German Publication No. 2,321,852), which is very strong and sufficient twisting, softening under this sufficient twisting state, unwinding of the twist to the first flammable starting area, or especially high return to the fiber. Elasticity is obtained by untwisting, such as by generating force. When a high elastic yarn made of natural fibers is processed into a fiber product in a conventional manner, the fibers in the fiber product are strongly rotated by the rotational retraction force, and the fiber product is twisted due to the rotational force, thereby deteriorating its appearance. Will be produced. When twisted in this way, the workability and wearability are impaired, and the appearance is not applicable to many applications of textile products.

The technical problem underlying the present invention is to give a high rotational resilience to a yarn made of natural fibers, and to provide a fiber product having sufficient elasticity and a product having a normal appearance even when using this yarn.

The technical problem of the present invention is realized as follows. In other words, the high elasticity yarn made of natural fibers gives high rotational recovery force and is combined in the fiber product. In this combination, the rotational recovery force of each yarn is supported by the adjacent yarns. More specifically, the rotational return of each thread is prevented by the rotational return force of an adjacent thread. This makes it possible to obtain a normal appearance while maintaining sufficient elasticity.

It is well known to apply this principle in the processing of elastic yarns made of synthetic fibers. For example, in the manufacture of stockings for example of machine knitted yarns of synthetic yarn, the yarns twisted in opposite directions are knitted in a continuous knitting system back and forth in succession to each other so that they rotate in opposite directions within each adjacent machine row. Make sure the thread has a return force. This principle applies only when high elasticity is obtained in the production of textile products made by synthetic yarns. Since such excellent elasticity itself is obtained by the elasticity of the fiber, such a treatment itself is not an essential condition in synthetic yarns. In addition, the synthetic fiber material is necessarily thermoplastic, and thus elasticity can be obtained simply by providing the easiest and effective softening.

The yarn made of natural fibers used in accordance with the present invention has a very high elasticity only by very strong weaving at the time of weaving, and when a very high elasticity is required, it must cause a very high rotational return force in the corresponding direction.

According to the present invention, it is possible to manufacture a fabric made of purely natural fibers only by combining the high elastic yarn made of natural fibers with restraint in the textile product. This fabric has the same elasticity as the fiber products made of synthetic fibers, while having excellent original touch, high hygroscopicity and warmth. It is also widely known that it should be made of elastic bonds for medical purposes. In this method, the weft of natural fiber with strong and sufficient unidirectional twist is made of natural fiber that is flexible and flexible. Squeeze together. Thereby, in the finished textile product, the weft yarns are partially rotated and return to a zigzag or wave shape, thereby making the weft yarns elastically engaged. The action used at this time is the opposite of the action of the present invention, and in the present invention fully supports rotational return of the yarn.

According to the present invention, a thread formed by a strong and sufficient twist, a soft fixation to a sufficient soft fixation state, a loosening of twists until the initial combusting state or more or more loosenings is adjacent to each other in the textile product with a strong rotational return force. It is possible to weave, for example, to reverse the rotational return force of the weft or warp yarns adjacent to each other in the fabric. Alternatively, in the present invention, the rotational return force of adjacent yarns is reversed even in a continuous knitting string while the knitted fabrics overlap. It is also sufficient to bond the two strands together, and the strong resilience resulting from twisting and subsequent loosening of the twist, or the resulting elastic resilience in the longitudinal direction of the fibers themselves interfere with each other. Or in this way the thread is adjacent to a corresponding support, for example a strong support of suitable elasticity.

The fiber product produced according to the present invention is steamed by known methods to relax its own yarn after manufacture. As a result, the yarn shrinks and the elastic return force due to elastic stretching is increased. In order to secure a considerably high elastic stretch and strong elastic recovery force, the yarn or the twisted yarn may be sufficiently combusted to the critical twist point. The critical firing point appears according to the degree of flammability, and in this flammable state, the increase in the yarn stiffness is always increased in response to the spin structure (adhesive force and flexibility) and the deformation state of the fiber due to the increase in frictional pressure. Saturated at Beyond this critical firing point, the fiber is twisted and cut.

In order to obtain the desired elastic return force in the longitudinal direction at the same time as the desired rotational return force, the thread may be loosened to the lead-free state of the initial flammable start state or more. In the combustible starting state after the twist is released, the yarn is turned, and the fibers are in the same relative relationship as that in the yarn at the commencement of combusting before combusting. In the lead-free state, the yarns are pivoted so that the fibers are approximately parallel to each other. In other words, it is usually as if little twist is applied. If the yarn is unleashed or unleashed more than that, then there is a risk that very short staple fibers, such as melancholy or cotton, will be released from their spin bonds and the threads will be scattered. According to the present invention, in the yarn of this kind, the positive yarn length component released when the lead is unleaded to or above the lead free state is shorter than the length of the staple fiber. In order to prevent the thread from scattering when it is released to the lead-free state or longer, at least two strands of fibers may be smoked and sufficiently fixed, and then unrolled to the lead-free state.

Sufficient flammability or loosening is carried out by a ring weaving machine, in which the thread is generally wound after each process, or flammable and loosening is carried out by a combustor, friction spinning machine, or the like. In this combustor or friction spinning machine, when a process is carried out, it is combustible in either direction, and after being fixed, it is released in the opposite direction.

Thread or combustible yarns are immersed in ointment tablets before or after combustion, or in combustible condition, and the potential ointment action by these ointments is manifested in a sufficient combustible state. This fiber dipping is carried out in an immersion tank during combustion in the machine, or when the yarn is in strands or on cross bobbins before or after combustion. As the immersion material of the corresponding fiber, any known softening agent used for soft fixation in a predetermined state can be used when the same natural fiber is used. The ointment fixing agent of the yarn separates the two functional bodies and / or the multifunctional body of the fiber and contains a component which performs a predetermined shape fixing in a new soft state in a new state.

Reactive resins, dimethyldiethylene urea or mixtures thereof may be used for the ointment fixation of yarns or twisted yarns consisting of fibrillar fibers. In the present invention, a well-known compound can be used for the permanent press processing of cotton fabric for the cotton softening. For depression, well-known treatment agents can be used for the spindle treatment and stabilization of wool, while for fibers containing proteins such as depression and silk, the hair is permanent in permanent webs. Known compounds can be used to impart sustained modification to the.

The appearance of the ointment fixing action in the present invention is performed by releasing the potential ointment fixing action by acting relatively high temperature for a short time. Heaters with a temperature of more than 220 degrees Celsius can be used to fix the broken heart.

In the processing of natural dogs, a soft fixation agent that requires heating for soft fixation is used, and there is a risk that the sericin contained in the soft lead adheres to the fiber after the treatment of the present invention. In the treatment of natural dogs, pretreatment for sericin removal must be performed after the treatment of the present invention.

In order to facilitate processing, the fiber can be adjusted before softening, and this adjustment improves smoothness while antistatic treatment is carried out. As modifiers, aqueous emulsions of polysiloxanes and additives are used to reduce the electrostatic charging of the fibers.

As used herein, the term "fiber products" includes all fabrics, knits, fabrics, fabrics, bands, and welfare. In addition, the expression "thread" as used herein includes all kinds of fibers, for example, all fibers which are not endless, such as monofilament yarns or multifilament yarns.

When explaining the embodiment of the present invention in detail by the accompanying drawings showing an embodiment as follows. In other words, as shown in Fig. 1, in the fabric having elasticity in one direction, the warp yarn 1, which is not elastic in nature, that is, for example, a silk thread, is woven by the weft yarns 2a and 2b. . The weft yarn 2a has the rotation return force in the direction of arrow A, and the weft yarn 2b has the rotation return force which opposes each other in the arrow B direction.

For woven fabrics, the rotational return force of the warp is adjacent to this warp, with the rotational return force in the opposite direction through a combination of the warp mutually in the fabric and the warp inherent with no elasticity. Is transmitted to the slope. Accordingly, the rotational return force is supported by the rotational return force in which adjacent slopes oppose each other without causing rotation of the fiber.

This phenomenon can occur together in a certain section even in the angular wefts (2a), (2b) of FIG. 1, wherein the reaction of the rotational return force opposed to each other will only interact with each other through direct contact between the fibers. The stretch in the longitudinal direction of the fiber, ie the stretchability in the transverse direction in the fabric of FIG. 1, is not impeded at this time.

In the case of manufacturing the fabric which can be stretched in two directions, single yarn or plywood having rotational recovery force in the direction opposite to each other may be alternately arranged and used as a warp yarn. Such fabrics can be woven by known looms for weaving known stretch fabrics into a synthetic fiber base.

2 is another embodiment of the present invention. In this embodiment, the reaction force of the rotational return force is supported in the strand of combustible yarn itself. This false twist yarn in FIG. 2 has, for example, a test of silk and depression, which is sufficient as described above to fix it in a combustible state and to disengage the twist so that many turns are returned in the direction of arrow C. Have power. Around this screening (5), a high elasticity wall thread (6) manufactured in the same manner is combined, and the wall thread (6) is made of the same natural fibers or other natural fibers as the screening (5). and the direction of the rotational return force of the screening (5) are united in the opposite direction, that is, the direction of the arrow C _1. As a result, the elastic return force acting in the longitudinal direction of the wall thread 6 opposes the rotational return force of the screening 5. By the association of FIG. 2, the rotational return force or elastic return force generated by sufficient flamming, softening, and strong unwinding is maintained with each other. It does not occur either. The weaving yarn of FIG. 2 is woven using at least one of warp or weft yarn in a weaving machine for weaving elastic synthetic fibers, or is knitted by using at least one of weft or warp yarn by a conventional knitting machine. It is possible to do

In the combined yarn of FIG. 2, a non-twisted yarn having sufficient anti-twisting power may be adopted in place of the screening of natural fibers having sufficient flammability, softening and twisting. This lead-free yarn requires an anti-twisting force that is capable of supporting the longitudinal elastic return of the wall without intrinsic molding. In this way, the elastic elasticity of the longitudinal elasticity is remarkably large, for example, the false twisted yarn which is most suitable for cleats and orthopedic supporter stocking can be manufactured. As this false twisted yarn, the synthetic elastic core yarn is sufficiently covered by the wall yarn made of natural fibers over the whole body length, thereby eliminating the defects of the synthetic elastic core yarn. On the other hand, since the flammability of the wall yarn is sufficiently high and can follow the very large stretch of the elastic core, the elasticity in the longitudinal direction of the elastic fiber is not impaired.

When using natural fibers having no known elasticity and low elasticity as wall yarns, the flammability of elastic examination is significantly limited, or the wall yarns are normally wound around the examination state after the longitudinal elasticity of the examination due to excessive combustion of the walls. It will not return and the fabric will be defective.

FIG. 3 is a schematic cross-sectional view of a knit fabric for making stockings, for example, showing only a single knit structure, in which the knitted strings (a, b, c, d) made of natural fibers are continuously woven together. will be. The strings of heat (a, b, c, d) alternate with each other strongly and sufficiently combustible and fix this sufficient combustible state to loosen the twist until almost the first commencement of commencement, or It is being released over. In the manufacture of this knitted fabric, the yarns are fed into a knitting system which is connected back and forth to each other in a combustible state in the opposite direction. As a result, the yarns in the knitting rows a and c are given twist in the direction of the arrow D, while the yarns in the knitting rows b and d are applied in the opposite direction to the arrow E direction. .

As shown in the knitting rows perpendicular to the center of FIG. 3, twisting in opposite directions to each other inclines the knitting of each row in the opposite direction to give the knitting additional elasticity. In known knitted fabrics made of synthetic fibers, the warp of the knitted fabric by twisting in the opposite direction leads to an increase in the stretching action.

In the present invention, since the natural fiber itself used has a very high rotational resilience and exhibits a very high elasticity up to 500% elongation, the inclination of the knitted fabric is not necessarily a requirement. That is, according to the present invention, sufficient and large elasticity in all directions can be secured even in a strong knitted fabric in which there is no inclination of the knitting or very little. Next, practical examples of the manufacturing method are listed to ensure the textile product according to the present invention.

Example 1

(ix), strand half of the material and accidentally rest the rest. High elastic yarns are formed in both the coincidence and the left margin, and the silk is wound around the bobbin and a final fineness of 50/2 denier yarn is produced for each of the right and left twisted yarns.

The high-elasticity silk and the slope of melancholy prepared as described above by a Shuttleless machine made by Fabrykat Sulzer (Switzerland) are woven in amber cloth as follows. That is, the 50/2 denier haptic elastic yarn arranged in the weft yarn and the 50/2 denier ductile elastic yarn arranged in the weft yarn are staggered. Here, the weight ratio of the slope of depression to elastic weft is about 1: 1.

In this way, welfare having a permanent elasticity of 15-20% in the inclined direction is obtained.

Example 2

Fabrication of stretch fabrics for use in corset products.

In the same manner as in Example 1, fine grains and fine silk were used to refine the fineness from 78 deniers to the final fineness of 50 deniers, and at the same time, to impart elasticity.

Fibers made of polyurethane-based lucra (dupont's) or dolastane (bayer's) are twisted together with a high-elasticity yarn of this example by a twisting machine. At this time, the silk thread is sufficiently wound on the polyurethane to cover the polyurethane, whereby the material ratio of the nut polyurethane is 3: 1.

The fibers thus produced are woven into a woven fabric by a shuttleless weaving machine manufactured by Fabry Cat Sul.

In this way, a highly elastic returning fabric having 30-40% elasticity in both warp and weft yarns is obtained, and the necessary characteristics are provided in the supporting action of the corset product.

Example 3

Except for employing false twist yarn for the weft yarn, it is the same as in Example 2, and two kinds of natural dog fibers are used with 50 denier, and treated in the same manner as in Example 1, and sufficiently twisted, fixed and twisted by a ring twister. Loosen it. Ring twisters are burned by accident with a rate of 70T / m.

The inclined twisted yarn is joined to the left twisted wall thread in the same manner as in the second embodiment. The material ratio of walls and screening is 2: 1.

Example 4

Production of highly elastic stockings composed of 100% natural dogs with permanent elasticity.

A yarn obtained by refining immersion treatment in the same manner as in Example 1 using fine silk 27-29 denier china silk as a raw material is wound on a bobbin.

The high elastic fibers are twisted right in system 1 and twisted left in system 2. Knitting for women's thin pantyhose or stocking ponytails by a circular knitting machine with a single cylinder of 400 stitches of Fabrklat Lonati and a minimum number of hangs in the 34th range.

Dye with a suitable acid dye for the next dog or dye with a metal complex dye and finish with a suitable staking cloth.

분간 벨포어(bell four) 성형기로 성형한다. 성형한 두짝의 스타킹 포지를 20-22데니어의 섬도로 여자용 엷은 스타킹으로 마무리 한다.Dyed Stocking Forge 105 degrees Celsius

Molded by bell four molding machine for a minute. Two pairs of stockings forge which I formed are finished with thin stockings for women with 20-22 denier fine island.

According to the above production method, not only have high elasticity in all directions, but also have good elastic return force, and it is possible to manufacture a stocking bag which is widely applied to any stocking. In addition, this stocking forge can be washed sufficiently, and the elasticity is not lost even if washed several times.

Example 5

Production of women's slip of high elastic fiber by 100% natural dog with permanent elasticity

The raw material is Brazilian dog of 78 denier. After refining, the fineness is 50 denier similarly to Example 1.

In the same manner as in Example 1, immersion treatment, cleaning and weaving are performed with corresponding fineness.

In both the coincidence and the left margin, a high-elastic silk thread is formed, the thread being wound in a bobbin and woven into a large circular knitting machine with a 24 system of at least 22 hook-widths of Fabrykat Maier (West Germany).

(i), two strands of coincidentally high elastic 100% silk yarn are set into (ii) the first system. (iii), two strands of high elastic 100% silk yarn on the left edge, (iv), set as the second system. (v), thus staggered to all 24 systems.

As a result, the rib weave is flexibly woven. Long knits with high elasticity and elastic return in all directions are formed. This long knitted fabric is a ready-made feminine slip with the best wearability by its elasticity. Since this dough is washable enough, the production of colorless color does not discolor the ecru color by self-washing and does not lose its elasticity. Not only the excellent heat resistance and hygroscopicity of natural dogs is sufficiently maintained, but the twisted yarn that has undergone the above-described process is further improved by its shrinking property.

Example 6

Production of high-elastic men's socks of the depressant

Raw material… Wool (natural fleece) Worsted Yarn (Number 40/1)

Combine two strands of combustible worsted yarn with the number 40/1 with a multiaxial hoist to make a variable 40/2. And twist this by a ring twisting machine enough, and let it be a continuous twist of 720T / m.

This hard double yarn is wound up by a crossover bobbin.

Dyeing cross bobbin is dyed with acid dye with a ratio of 1: 10. Post-treat the pH 7.5 sodium diphosphate solution in the rolled-up state. Dry by centrifugation at 80 ° C in a pressure drier. Winding back to 1040T / m on a ring twister. At this time, twist of about 120 T / m remains in the reverse direction.

This twist tries to go back in a wound state and contracts like a spiral winding spring.

The result is a permanent stretch that allows for at least 200% stretch. Wind up the finished thread on the bobbin.

Woven with a circular knitting machine of number 14 (minimum hang nose range) of Fabrykat Eppinger.

In system 1, a twisted number 40/2 thread is set. In system 2, a thread of number 40/2 twisted left is set. The ribs in the post and left lines are 2: 3.

Sock for men is obtained by crushing. The final product is relaxed and shrunk by firing in saturated steam at 105 degrees Celsius for 10 minutes.

The Heliot molding machine will mold at 115 degrees Celsius for 4 minutes.

So far, only 2 gross of high elasticity new socks are obtained, which is equivalent to only 2 gross for synthetic fiber elastic socks, which normally required 6 gross to make the product, and is much more conventionally worn for non-elastic wool socks. Sex is good. These socks can be washed at 30-35 degrees Celsius, just like in a melancholy knitted fabric. Even after multiple washings, elasticity is preserved permanently.

The method of the present invention is also applicable when synthetic fibers or synthetic yarns are mixed, and the blend is preferably used for the purpose of improving the abrasion resistance of the fibers rather than natural fibers or for other purposes.
