Description
Technical Field
The invention belongs to the technical field of collars, and relates to a method for realizing the anti-hemming characteristic of a collar by locally introducing thermoplastic elastomer yarns.
Background
The collar is a clothing part attached to the neck of a human body and plays a role in protection and decoration. At present, the requirements on the performance of knitted collars are mainly two items: firstly, the contact comfort is good when the garment is worn, and the garment is warm in winter and smooth in summer; and secondly, the fabric can keep flat and stiff for a long time, namely, the fabric still keeps a good shape after being worn for a long time or being washed by water for many times, does not curl or wrinkle and keeps the aesthetic feeling of the shape. The neck angle of the prior art collar is easily curled, so that the appearance of the collar is deteriorated after being worn for a certain time.
Knitted collars, such as collars made of cotton, regenerated cellulose fiber and the like, have been able to achieve good contact comfort at present. However, collars made of cotton, regenerated cellulose fiber and other raw materials in the market generally have the problems that the original smoothness and stiffness of the collars cannot be maintained due to the fact that the collars are curled and wrinkled after about 5-10 times of washing, and the curling of the collars appears at the collar corners of the collars, so that if the curling problem can be solved from the collar corners, the appearance of the collars can be directly improved.
In the prior art, generally, the other part of fabric with a memory function is directly sewn at the collar corner part of a collar, or an inserting piece is added to reinforce the collar corner, so that the function of preventing the collar corner from curling is achieved, and the collar corner is stiff and conformal, for example, patent document 1 (publication No. CN209314981U) has the function of memorizing the shape by sewing the collar corner on the front side of lapel, the memory collar corner consists of PTT and memory cotton, and the problems of easy collapse of the collar corner and poor version of the collar can be solved; patent document 2 (publication No. CN204104847U) sets a cloth liner between the collar surface and the inside of the top collar near the collar tip, the shape of the cloth liner matches the shape of the collar tip, the shirt collar is shape-retaining, and the collar corner of the collar is prevented from curling outwards; patent document 3 (publication No. CN203353746U) adds iron sheet to the outside of the collar tip, so that the collar is more rigid, convenient and fast to install, and can withstand multiple washing without deformation; patent document 4 (publication No. CN 203505594U) adds a reinforcing member to the neck corner portion so that the neck corner cannot be bent and folded to achieve a shape-retaining effect; in patent document 5 (publication number CN202949976U), the insert is arranged on the back of the lapel along the bisector of the collar tip, and the addition of the insert ensures that the collar corner of the collar is stiff and smooth; however, the method of securing the shape of the neck corner by reinforcing the neck corner is more suitable for sewing a collar of a woven fabric, the knitted collar is integrally formed, the step of adding the reinforcing sheet is complicated, and the reinforcing portion is easily exposed, which not only increases the cost but also affects the appearance of the fabric.
In the prior art, elastic memory filaments are usually selected to be interwoven with other yarns to be woven into a memory type elastic knitted fabric, so that the function of preventing collar corners from curling is achieved, and collar fabrics are stiff and have good shape retention.
Therefore, there is a need for a knitted neck collar having good contact comfort, good appearance and neck corner curl resistance.
Disclosure of Invention
The present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a knitted neck collar having good contact comfort, good appearance, and anti-curl properties at the neck corner.

The method for preparing the knitted collar with the anti-hemming characteristic comprises the steps that the diameter of a main yarn is 0.1-1.0 mm, the diameter of a thermoplastic elastomer yarn is 0.08-0.25 mm, and the diameter of the main yarn is not smaller than that of the thermoplastic elastomer yarn;
the main yarn is single yarn, strand yarn or filament yarn, and is spun by more than one of cotton, hemp, silk, wool, regenerated cellulose fiber, regenerated protein fiber, terylene, chinlon, polypropylene fiber, spandex and acrylic fiber, the thermoplastic elastomer yarn is polyurethane yarn (TPU), polyester yarn (TPEE), polyamide yarn (TPAE), organic fluorine yarn (TPF) and polyolefin yarn (TPO, TPV) or mixed multifilament thereof, only some common materials which can be used for manufacturing the thermoplastic elastomer yarn are listed, the protection range of the invention is not limited by the main yarn, the material of the thermoplastic elastomer yarn is not limited by the main yarn, as long as the thermoplastic elastomer yarn has better shape retention, the thermoplastic elastomer is environment-friendly, nontoxic, comfortable in hand feeling and exquisite in appearance, has rubber elasticity at normal temperature, and can be plastically molded at high temperature, so the thermoplastic elastomer yarn is suitable for weaving collars with better shape retention;
certain extrusion force is more than 1KPa, and certain time is more than 3 seconds;
the knitted collar having the anti-curling property is not curled, wrinkled or twisted when washed more than 20 times in the drum type washing machine; the knitted collar with the anti-hemming characteristic is 30-45 cm in length, 5-10 cm in width and less than or equal to 5mm in thickness, is generally rectangular and cannot be cut, can be subjected to thread separation after being cut, is in the length direction along the weaving direction of the fabric, and is suitable for a neck circumference or used clothes;
the bending rigidity of the contact part of the knitted collar with the anti-hemming characteristic and a human body is 6-15 mN & cm, and the air permeability is 25-30 mm/s.
The invention mechanism is as follows:
the invention introduces the thermoplastic elastomer yarn in the collar corner knitting area on the basis of adopting the rib knitting collar to improve the easy curling characteristic of the collar corner part, and then carries out compression and heat setting on the collar, and the collar corner after heat setting has good shape stability and lower cost than the collar with full width plated yarn.
The invention combines the rib weave with the liner, the weft insertion and the plating weave and selects specific yarns, thereby obviously improving the shape-retaining capability of the fabric, and the main reasons are that: 1) the rib tissues have good shape stability; 2) the fabric texture comprises thermoplastic elastomer yarns, and the thermoplastic elastomer yarns have high elastic resilience and can improve the resilience of the fabric after the overall shape is changed, so that the shape retention capacity of the fabric is improved; 3) the thermoplastic elastomer yarn is subjected to compression heat setting treatment, is fixed in a coil form, forms a stable structure in the fabric, is in a stable state with low energy, has good shape stability, and is not easy to change under the action of external force at normal temperature; 4) the thermoplastic elastomer yarn is not easy to break, and can keep higher shape recovery capability for a long time; 5) the thermoplastic elastomer yarn and the main yarn are synchronously knitted at the collar corners, and the contact points between the thermoplastic elastomer yarn and the main yarn are more, namely, the friction force is large, so that the collar corners are not easy to curl after being washed.
In the prior art, the full-width plating of the collar can cause the part of the collar surface, which is in contact with a human body, to be harder, and the shape-keeping effect is achieved, but the whole comfortable sensation is reduced. Firstly, the bending stiffness is resistant, the smaller the bending stiffness is, the softer the fabric is, the better the comfort is, the bending stiffness of the collar fabric in the prior art is between 25 and 35mN & cm, while the bending stiffness of the part of the collar fabric in contact with a human body is between 6 and 15mN & cm, so that the collar fabric has softer touch when being worn; secondly, the air permeability of the fabric is higher, the contact is more comfortable, the air permeability of the collar in the prior art is 25-30 mm/s, the air permeability of the part of the collar fabric in contact with a human body is 30-40 mm/s, and the advantage is prominent.
In addition, the method of the invention is different from the prior art which ensures the shape of the collar corner by reinforcing the collar corner, so the appearance of the fabric is good.
According to the invention, the thermoplastic elastomer yarn is introduced into the collar corner area, the positions and the weaving sequence of yarn mouths with the elastomer yarn at two ends of the fabric are required to be reasonably arranged when the fabric is woven, the yarn mouths at two sides are required to alternately enter and exit until the local weaving area is finished, and once the entering and exiting time of the yarn mouths at two sides is wrong, the yarn mouths collide and hit the needle, the collar weaving fails, and the equipment is damaged. In addition, the local introduction of the elastomer yarn requires the needle reduction according to requirements, and the position of each line of yarn nozzles for weaving the collar is different, so that great challenges are brought to the arrangement of the yarn nozzle positions. Particularly, when the thermoplastic elastomer yarn is introduced into the collar corner area and the rib weave and the weft insertion weave are combined, the weft insertion yarn is not fed into a needle hook, so that the yarn padding longitudinal angle of the yarn is determined by the positions of the knitting needles at the two ends of the woven fabric and the positions of the yarn mouths, when the full-width weft insertion is carried out, the yarn mouths can be adjusted to be far away from the woven area, the yarn padding longitudinal angle of the weft insertion yarn is reduced, the looped yarn can completely press the weft insertion yarn, and the phenomenon that the weft insertion yarn is reversely pulled away from the knitting needles when the next row of yarn mouths are reversely woven to cause weft insertion failure is avoided.
Has the advantages that:
(1) according to the knitted collar with the anti-hemming characteristic, the collar corner after heat setting has good shape stability, and cannot deform after being washed for many times;
(2) the knitted collar with the anti-hemming characteristic has the advantages of smooth collar surface, good appearance, soft touch feeling, comfortable wearing and suitability for long-time wearing by human bodies;
(3) the knitted collar with the anti-hemming characteristic has the advantages of simple preparation process and lower cost, and is suitable for large-scale production.
