Description

A kind of high conformal knitted collar and its preparation method

technical field

The invention belongs to the technical field of collars, and relates to a knitted collar with high shape retention and a preparation method thereof.

Background technique

Collars are attached or detached ribbons of various shapes and sizes used to adorn the neckline of clothing. Collars can be divided into round collars, V-necks, square collars, stand-up collars, lapels, etc. according to the collar type. Among them, the lapel is the collar shape formed by turning the collar outward so that the outer collar falls on the shoulders. It is suitable for Polo shirts, suit shirts, trench coats or doll collars for women's clothing.

There are two main requirements on the performance of the collar. One is that the wearer’s neck should have a comfortable feeling when in contact with it, and the other is that it should be able to remain flat and stiff for a long time, that is, it must have good wear resistance after long-term use or multiple washings. Shape stable and won't curl or wrinkle. Knitted collars have been able to achieve good contact comfort, such as collars made of cotton, viscose and other materials. However, the collars made of cotton, viscose and other materials generally have curls and wrinkles after about 5-10 washes on the market and cannot keep the original smoothness and stiffness of the collars.

Studies have shown that during the washing process of knitted fabrics, fibers swell after absorbing moisture, causing the balance of internal forces in the fabric to be broken, and twisting causes the shape of the fabric to change to seek a new balance. Therefore, in the design process of the collar, efforts should be made to improve the shape stability of the collar during the washing process, so as to solve the shape change problem caused by washing while ensuring the collar has good contact comfort.

In the existing technology, chemical fiber filaments with high elastic recovery are usually added to the collar for co-weaving, and the shape stability of the fabric is improved by improving the recovery ability after shape change. But the presence of different materials on the same surface affects the aesthetics of the fabric and the comfort of contact; the prior art also usually divides the collar into multiple layers, and stitches or thermally bonds the fabric with a stable structure to the collar, but the effect Poor, and reduces air permeability, increases the complexity and cost of weaving.

Patent document 1 (publication number CN109371550A) discloses the following technology: the blended yarn formed by blending cotton fiber and modal fiber and Lycra spandex yarn are synchronously woven to prepare an elastic and soft knitted fabric. However, this method cannot ensure the uniform distribution of blended yarns and spandex filaments on the fabric surface, and reduces the fabric's contact comfort. At the same time, spandex is prone to breakage and aging after repeated washing, resulting in reduced shape recovery ability, thereby shortening the fabric shape. hold time.

Patent Document 2 (Publication No. DE4138578A1) discloses the following technology: heat-fusible materials such as polyethylene or polyester are prepared into grid sheets, and then connected with textile materials by heating and pressing. However, the effect of thermocompression bonding by this method is not good, and the fabrics of different layers are prone to detachment; the sheet material and the knitted fabric are easily bonded, and the multi-layer lamination reduces the original air permeability of the fabric, and the contact part of the collar and the neck The comfort level is reduced, and the process is complicated and the processing cost is high.

Therefore, it is urgent to study a knitted collar with good contact comfort and shape retention.

Contents of the invention

One of the purposes of the present invention is to solve the problem of poor shape retention of knitted collars in the prior art, and the second purpose is to solve the problem that the knitted collars of the prior art cannot have good contact comfort and shape retention at the same time . The knitted collar of the invention has good adaptability to the neck of a human body, and the original shape will not be changed after repeated washing.

In order to achieve the above object, the scheme adopted by the present invention is as follows:

A method for preparing a high-conformity knitted collar, first weaving a rib fabric by plating technology, and then performing tension heat setting on it to obtain a high-conformity knitted collar;

At least two yarn feeders are used for weaving, one for main yarn and the other for thermoplastic elastomer yarn. Since the weaving parameters of the two yarns are different, different yarn feeders are required to realize;

During the weaving process, by adjusting different laying angles, the main yarn is always on the front of the coil, the thermoplastic elastomer yarn is always on the reverse side of the coil, and the main yarn covers the thermoplastic elastomer yarn;

Only tense heat setting can be used for heat setting, and loose heat setting cannot be used, because there is a fold line in the collar, so that part of the collar is in contact with the neck, and the other part rests on the shoulder. It requires a certain amount of force to form the fold line and squeeze The surface of the collar makes the other parts have better flatness except the fold line, and the relaxation heat setting cannot achieve the desired effect;

Tension heat setting refers to the process of keeping the folded collar shape of the fabric under a certain extrusion force, and heating it at a certain high temperature for a certain period of time, and then cooling it rapidly to a certain low temperature at a rate higher than 120K/min;

A certain high temperature is higher than the softening temperature of the thermoplastic elastomer yarn and lower than the softening temperature or ignition point of the main yarn, and a certain low temperature is lower than the softening temperature of the thermoplastic elastomer yarn.

In weft knitting, the yarns are sequentially placed on the corresponding knitting needles of the weft knitting machine along the weft direction to form loops, and are interlaced longitudinally to form weft knitted fabrics. When yarns of various materials are fed through the same yarn feeder for weaving, the distribution of the yarns on the surface of the fabric is random; The feeding angle of the yarn is different, so as to realize the control of the layer position of the yarn of different materials; the main yarn is always on the front of the coil, and the thermoplastic elastomer yarn is covered by the main yarn, which is always on the reverse side of the coil. All appear as front loops, so only the main yarn is exposed on the surface of the fabric;

Fold the woven fabric according to the shape of the collar, and heat it with an iron, an oven or a heat setting machine. The heating temperature is higher than the softening point of the thermoplastic elastomer yarn. Different thermoplastic elastomer yarns require different temperatures for softening. The material determines the heating temperature; when the thermoplastic elastomer yarn is heated, the force between some macromolecular segments is quickly destroyed; a stable extrusion force is applied to maintain it in the desired shape; the heating time includes heat penetration time and molecular adjustment time , the heat is from the surface to the inside, the thermoplastic elastomer yarn reaches the softening temperature after a certain period of time, and its molecular segments are broken, rearranged under the action of external force, and transformed into the target state after a certain period of time; after the heating is completed, it is cooled and shaped, and the temperature Rapid cooling to less than the softening point of the thermoplastic elastomer yarn, at this time, the macromolecules quickly rebuild a new intermolecular force in the new position, and fix it, and the fabric is in a stable state with low energy.

In the prior art, the collar generally adopts rib weave, which has certain elasticity and good dimensional stability. The general use of plating weave is to change the design and color or to use different materials for ground yarn and plating to form functional fabrics, such as polyester fabrics. For the effect of covering cotton, plating requires a special yarn feeder or a machine with such functions, which will increase production costs, so collars generally rarely use plating.

The present invention significantly improves the shape retention ability of the fabric by combining the rib weave and the plating weave and selecting specific yarns, mainly because: 1) the rib weave itself has good shape stability; 2) the fabric weave contains thermoplastic elastic Body yarn, thermoplastic elastomer yarn has high elastic recovery, which can improve the recovery ability of the overall shape of the fabric, and then improve the shape retention ability of the fabric; 3) The thermoplastic elastomer yarn has undergone tension heat setting treatment, and its The shape is fixed, and a stable structure is formed inside the fabric, which is in a stable state with low energy and has good shape stability. It is not easy to change due to external force at room temperature; 4) The thermoplastic elastomer yarn itself is not easy to break , can maintain a high shape recovery ability for a long time; 5) The thermoplastic elastomer yarn and the main yarn are woven synchronously, and there are many contact points between the two, that is, the friction force is large. During the washing process, the friction of the main yarn is reduced. Deformation; 6) The thermoplastic elastomer yarn is covered by the main yarn, which reduces the ultraviolet aging (commonly known as photoaging) and prolongs the duration of shape retention.

In addition, when the main yarn has good contact comfort, the high-conformity knitted collar of the present invention can also have good contact comfort. Poor TPE yarns are all hidden inside the fabric, where they cannot come into direct contact with the skin.

As a preferred solution:

In the preparation method of a high-conformity knitted collar as described above, the mass addition of the thermoplastic elastomer yarn is 15% to 70% of the sum of the mass addition of the thermoplastic elastomer yarn and the main yarn. The proportion can be adjusted properly, but it should not be too high or too low, too high will cause the fabric to feel worse, and it will be too hard after heating; too low will not achieve the shape retention effect.

A method for preparing a high-conformity knitted collar as described above, the diameter of the main yarn is 0.2-1.0mm, the diameter of the thermoplastic elastomer yarn is 0.08-0.25mm, and the diameter of the main yarn is not less than the diameter of the thermoplastic elastomer yarn Generally, the finer the yarn, the finer the fabric surface, and the better the contact comfort. At the same time, the density after heat treatment shrinkage is higher, the fabric stiffness is greater, and the shape retention is better. The diameter of the main yarn and the diameter of the thermoplastic elastomer yarn are matched to each other. Yes, the main yarn needs to be thicker than the TPE yarn or at least as thick as both to achieve good coverage.

A method for preparing a high-conformity knitted collar as described above, the main yarn is spun from one or more of cotton, hemp, wool, regenerated cellulose fiber, polyester, nylon, spandex and acrylic fiber, and the main yarn can be Purely spun yarn, such as cotton pure spun yarn, regenerated cellulose fiber pure spun yarn, or blended yarn, such as polyester-cotton blended yarn, etc. The specific material is not limited to this, as long as it has good contact comfort That is, the thermoplastic elastomer yarn is polyurethane-like silk (TPU), polyester-like silk (TPEE), polyamide-like silk (TPAE), organic fluorine-like silk (TPF) and polyolefin-like silk (TPO, TPV) or their Mixed multifilament yarns, here are only some common materials that can be used to make thermoplastic elastomer yarns, the protection scope of the present invention is not limited thereto, and the material of thermoplastic elastomer yarns is not limited thereto, as long as it is ensured that it has better shape retention Just sex.

For the preparation method of a high-conformity knitted collar as mentioned above, the certain extrusion force is greater than 5cN, and the certain time is greater than 3 seconds. When heating, the internal stress of the knitted fabric is released, and it will twist itself. According to the estimation of the pressure, it needs at least 5cN The consideration of time is that it takes at least 2 seconds for the temperature to reach the inner layer from the surface of the fabric, and it takes at least 1 second for the process of rearranging the internal macromolecular chains to the target state after heating. If the pressure and temperature are too small, stable thermoplastic cannot be formed. Elastic layer, reduced fabric shape retention.

The present invention also provides a high-conformity knitted collar prepared by the method for preparing a high-conformity knitted collar as described in any one of the above. It is a kind of organization formed by compounding the ground organization and the plaiting organization;

Contains at least one main yarn exposed on the surface of the fabric and a thermoplastic elastomer yarn hidden inside the fabric as a ground yarn. The thermoplastic elastomer yarn presents a curved shape of a coil (when the temperature is below the softening temperature of the thermoplastic elastomer yarn, it tends to A force of 20cN is applied to the thermoplastic elastomer yarn for 1 minute, the shape does not change, and the fixed shape of the coil is still present, and the coils in the fabric are intertwined to form a stable network structure).

As a preferred solution:

The high-conformity knit collar as described above, the high-conformity knit collar will not curl, wrinkle or twist after 10-15 washes in a front load washing machine.

The above-mentioned high-conformity knitted collar, the rib weave is 1+1 rib weave, 1+1 full stitch rib weave, 2+1 rib weave, 2+2 rib weave, 2+3 rib weave or 3+3 rib weave The rib has better elastic recovery, and the main purpose is to improve the shape retention ability. The rib of the present invention is not limited to this, and only some common ribs are listed here; the plating is two-line plating, three-line Plating organization or four-thread plating organization, in practice, the common and woven platings are the above three types. Note that the two-thread, three-thread, and four-thread here refer to professional terms, and do not refer to the use of 2, 3, or 4 threads. Yarn, but refers to the number of layers of yarn, such as two-thread plating organization, there is surface yarn A and ground yarn B. At this time, A and B can be more than one yarn or more than one material, as long as part A is guaranteed The yarn of part B is always covered on the yarn of part B, that is, two-thread plating, three-thread and four-thread can be reasoned equally, and plating can ensure that only the main yarn with good contact comfort on the surface is in contact with the human skin.
