Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finishing process for a woven fabric comprising at least a weft yarn made of polytrimethylene terephthalate fiber. More specifically, the present invention provides a processing method for finishing the fabric in a standardized fabric width with a soft feel and excellent dimensional stability.

[0002]

2. Description of the Related Art In dyeing and finishing a woven fabric composed of various fibers, it is important to finish the woven fabric to a specified width. The dyed woven fabric passes through a sewing process and is commercialized. In particular, in the sewing process, each part is cut to make a product, but the method of taking each part is determined so that the loss of the fabric is reduced. Therefore, it is a problem that the woven fabric becomes narrower than the standard width because the planned parts cannot be removed and extra fabric is used, which leads to an increase in cost.

[0003] Polyethylene terephthalate fibers are particularly excellent in heat-setting properties.
When a general dyeing finishing process such as presetting, dyeing, and finishing is performed, the presetting usually has a woven fabric width (a set width of a heat setter of −1 to a cloth width after scouring is set to −1 to 1). In the finishing process, the width is set to 2 to 5% of the width after dyeing, but the obtained fabric is finished to a standard width and has excellent dimensional stability. Further, the texture hardly changes depending on the presence or absence of the tentering.

On the other hand, polytrimethylene terephthalate fiber is a fiber having a low Young's modulus and a high elastic recovery rate,
It is a fiber with a soft feel comparable to nylon fiber, but if a woven fabric made of polytrimethylene terephthalate fiber is dyed and finished in the same way as a woven fabric made of polyethylene terephthalate fiber, the finished width will be larger than the standard width. Only very narrow fabrics can be obtained. Therefore, in the case where the width contracted after the presetting is set again to the standard width at the time of finishing processing and the tentering set is performed, the texture becomes very hard due to the tentering, and the dimensional stability deteriorates due to the tentering. Further, despite the widening of the standard width, the fabric was not completely set, and only a fabric narrower than the standard width was obtained.

[0005] As described above, the woven fabric made of polytrimethylene terephthalate fiber has a poor setting property and cannot be finished according to the set value even when the width is set to a standard width by presetting or finishing. In addition, there is a problem that the texture becomes hard when the tentering set is performed, and it is difficult to finish the fabric to a standard fabric width with a soft texture and excellent dimensional stability in a dyeing process similar to a normal polyethylene terephthalate fiber fabric. there were.

[0006]

SUMMARY OF THE INVENTION The present invention provides a fabric which is made of polytrimethylene terephthalate fiber which meets such a demand and has a soft feel, excellent dimensional stability and finished to a standard fabric width. Things.

[0007]

Means for Solving the Problems As a result of intensive studies on the above problems, the present inventors have found that the purpose of solving the problems can be achieved by dyeing and finishing in a specific method. Reached. That is, in the present invention, after refining a woven fabric in which at least the weft is composed of polytrimethylene terephthalate fibers, a width of 3% or more of the woven fabric width after the refining is preset, and then dyed and finished. And a dyeing and finishing method characterized by the following.

Hereinafter, the present invention will be described in detail. In the present invention, the polytrimethylene terephthalate fiber refers to a polyester fiber having a trimethylene terephthalate unit as a main repeating unit, and the trimethylene terephthalate unit has about 50 mol% or more, preferably 70 mol% or more, and more preferably 80 mol%. Above, more preferably 90 mol% or more. Therefore, the total amount of the other acid component and / or glycol component as the third component is within a range of about 50 mol% or less, preferably 30 mol% or less, further 20 mol% or less, and more preferably 10 mol% or less. Polytrimethylene terephthalate contained.

[0009] Polytrimethylene terephthalate is produced by polycondensing terephthalic acid or a functional derivative thereof with trimethylene glycol or a functional derivative thereof in the presence of a catalyst under appropriate reaction conditions.
In this production process, an appropriate one or two or more third components may be added to form a copolymerized polyester,
Further, polyesters other than polytrimethylene terephthalate such as polyethylene terephthalate and the like, nylon and polytrimethylene terephthalate may be separately produced, then blended, or composite-spun (sheath core, side-by-side, etc.).

The third components to be added include aliphatic dicarboxylic acids (oxalic acid, adipic acid, etc.), alicyclic dicarboxylic acids (cyclohexane dicarboxylic acid, etc.), and aromatic dicarboxylic acids (isophthalic acid, sodium sulfoisophthalic acid, etc.). ), Aliphatic glycols (ethylene glycol, 1,2
-Propylene glycol, tetramethylene glycol, etc.), alicyclic glycols (cyclohexane dimethanol, etc.), aliphatic glycols containing aromatics (1,4-bis (β-hydroxyethoxy) benzene, etc.), polyether glycols (polyethylene glycol) , Polypropylene glycol and the like), aliphatic oxycarboxylic acids (ω-oxycaproic acid and the like), aromatic oxycarboxylic acids (p-oxybenzoic acid and the like) and the like. Compounds having one or more ester-forming functional groups (such as benzoic acid or glycerin) can also be used as long as the polymer is substantially linear. Further, matting agents such as titanium dioxide, stabilizers such as phosphoric acid, ultraviolet absorbers such as hydroxybenzophenone derivatives, crystallization nucleating agents such as talc, lubricating agents such as Aerosil, antioxidants such as hindered phenol derivatives, It may contain a flame retardant, an antistatic agent, a pigment, a fluorescent whitening agent, an infrared absorbing agent, an antifoaming agent, and the like.

In the present invention, the polytrimethylene terephthalate fiber is spun at a take-up speed of about 1500 m / min to obtain an undrawn yarn and then twisted at a rate of about 2 to 3.5 times. Any of a direct drawing method (spin draw method) in which the drawing and twisting step is directly connected and a high-speed spinning method (spin take-up method) with a winding speed of 5000 m / min or more may be adopted. In addition, the form of the fiber may be a long fiber or a short fiber, may be uniform in the length direction or may be thick and thin,
Round, triangular, L-shaped, T-shaped, Y-shaped, W-shaped,
Polygonal type such as eight leaf type, flat, dog bone type, multi leaf type,
It may be hollow or irregular.

Further, the form of the yarn may be a spun yarn such as a ring spun yarn or an open-end spun yarn, a multifilament raw yarn (including an ultrafine yarn) having a single yarn denier of about 0.1 to 5 denier, a sweet twisted yarn or the like. Strong twisted yarn, mixed yarn, false twisted yarn (PO
Y (including a drawn false twisted yarn), and a fluid jet processed yarn such as a so-called Taslan processed yarn. In addition, other fibers such as natural fibers such as wool are blended (silospan or silofil, etc.) and entangled blended fibers (with high shrinkage yarns) within a range of usually 30% by weight or less within a range not to impair the object of the present invention. May be mixed by means such as different shrinkage mixed fiber yarns, alternate twisting, composite false twisting (elongation difference false twisting, etc.), and two-feed fluid jetting.

The present invention relates to a woven fabric in which at least the weft is made of polytrimethylene terephthalate fiber. When the weft is a polytrimethylene terephthalate fiber, the dyeing and finishing method of the present invention is effective. The warp has no effect on controlling the width of the woven fabric, and may be any fiber such as polytrimethylene terephthalate fiber, other synthetic fiber, semi-synthetic fiber, or natural fiber, These fibers are blended (silospan, silofil, etc.), entangled blended fibers (different shrinkage mixed fibers with high shrinkage yarns, etc.), twisted, composite false twist (elongation difference false twist, etc.), 2-feed taslan processing, etc. Or one or several of these fibers may be alternately woven into the warp.

The type of the woven fabric used in the present invention is not particularly limited, and may be a flat structure, a twill structure, a satin structure, or a structure combining these structures. Also, the loom for weaving the fabric is not particularly limited, and can be produced using an air jet loom, a water jet loom, a rapier loom, a gripper loom, a shuttle loom, or the like.

Next, the dyeing and finishing method of the present invention will be described. An object of the present invention is to refine a woven fabric in which at least the weft is composed of polytrimethylene terephthalate fiber, and then perform a preset of 3% or more of the width of the woven fabric after scouring, and then perform dyeing and finishing. Only by adopting the dyeing finishing method can a product with a soft texture, excellent dimensional stability and a woven fabric width according to the standard be obtained for the first time.

The present invention is a dyeing and finishing method characterized by performing a specific pre-setting after scouring, in which the fabric is relaxed and shrunk in advance by scouring to suppress the amount of shrinkage and shrinkage stress during pre-setting. The width direction property can be controlled with a width insertion preset of 3% or more. The scouring conditions are not particularly limited, but are 50 ° C to 100 ° C.
At a temperature of 5 ° C. for 5 minutes to 30 minutes, it can be performed continuously in a spread form or in a batch form in a rope form, and under these conditions, the shrinkage in the width direction is usually 2% to 20%, and 80 ° C. to 100%. It is preferable to perform scouring in the range of ° C. to shrink in advance.

The auxiliary agent used in the scouring may be any as long as it can remove oiling oils and sizing agents adhering to the greige machine, even if a known surfactant for scouring or an alkali is used to enhance the cleaning effect. Good. As the scouring device, a known device such as an open soaper or a wins can be used. Drying after scouring may be performed as long as adhering moisture can be removed, and can be usually performed by a cylinder dryer, a heat setter, a short loop dryer, or the like. The drying condition is usually 100 ° C.
１４０140 ° C. for 5 seconds or more. As a device, a short loop dryer in which tension is not easily applied to the woven fabric is preferable in terms of softening the texture. There is no problem even if the fabric is scoured and dried at room temperature.

In order to obtain the effects of the present invention, it is particularly important that the width of the woven fabric after the scouring by the presetting is 3% or more. When the fabric is preset with a width of 3% or more, the fabric is set according to the preset width at the time of presetting. At this point, the texture of the fabric is flexible, and there is no change in the fabric width even after dyeing. By doing so, it is finished to the standard width. In addition, this fabric can provide a fabric having a soft hand and excellent dimensional stability.

However, when the width of the woven fabric is preset at less than 3%, the width of the woven fabric becomes narrower than the set width at the time of the presetting, and at this point, the texture of the woven fabric becomes hard. Even after dyeing and finishing, the texture does not change and a flexible fabric cannot be obtained. Further, when the width is set to less than 3%, the width is reduced further by shrinking even in the dyeing process. If the woven fabric is finished to the standard width by finishing processing in order to finish the woven fabric to the standard width, the set is not effective even in the finishing process, the width becomes narrower than the standard width, and the woven fabric according to the standard cannot be obtained. Further, the woven fabric has poor dimensional stability and hard texture.

The upper limit of the width insertion is the maximum shrinkage value of the woven fabric after scouring (the value of the shrinkage ratio of the woven fabric width when the same treatment as the preset is performed in a free state without fixing the width direction of the woven fabric). The value varies depending on the amount of greige, the scouring condition and the preset condition, and is a maximum of about 20%. The width of the preset in the present invention is expressed by the following formula based on the width of the refined fabric and the set width of the outlet of the preset device.

[0021]

(Equation 1) The width of the scoured fabric referred to herein is the minimum width of the fabric in a state where the scoured and dried fabric is placed on a horizontal table and wrinkles are stretched without applying tension as much as possible. Good value,
The preset width of the outlet of the preset device is the preset width of the exit of the heat treatment zone of the preset device. Generally, the width of the presetting device can be set at three points: the entrance of the presetting device, the entrance of the heat treatment zone, and the exit. In the present invention, the width of the exit of the heat treatment zone is set to a predetermined setting width. The object of the present invention is achieved, but it is better to avoid over-width than the width of the scoured fabric in the presetting device, for example, at the entrance of the heat treatment zone, as this impairs the texture of the fabric.

In a preferred embodiment of the present invention, the width of the presetting device is set to the set width according to the present invention, and both the entrance and the exit of the heat treatment zone are set to the same setting width as the entrance of the presetting device. Set the width at the entrance of the setting device, the same setting width for all), or set the width of the entrance of the presetting device to the width of the refined fabric,
It is preferable that the width and width of the heat treatment zone are set at the inlet and outlet of the heat treatment zone, and the width is preset at the width of the heat treatment zone. In addition, you may change the setting width of three places (width insertion rate) as needed.

The preset condition in the present invention is 140
The drying may be carried out for 10 seconds or more at a dry heat of 200 ° C. to 200 ° C. In particular, it is preferable to perform the drying in the range of 160 ° C. to 180 ° C. for about 20 seconds to 90 seconds in order to obtain a sufficient setting effect. In particular, at a temperature exceeding 200 ° C., the texture may become hard. If necessary, steaming (saturated steam or heated steam) may be performed, and the steaming may be performed in the range of 100 ° C. to 140 ° C. for 10 seconds or more. The apparatus for performing the presetting is not particularly limited as long as the apparatus can control the width of the heat treatment and the fabric, and a treatment method convenient for handling in a subsequent step may be selected. Specific examples include heat setters manufactured by Wakayama Iron Works, Kyoto Machinery, or Hirano Metals.

The method of dyeing and finishing a woven fabric in the present invention is not different from the conventional method of dyeing and processing a woven fabric of polyethylene terephthalate fibers after presetting after scouring. A general dyeing finishing process is a process of dyeing and finishing (including the application of a finishing agent and a finishing set). In particular, the most preferable condition of the finish processing of the present invention is that this step is set with a certain width. By performing the finishing process with a certain width, a fabric having a soft texture and excellent dimensional stability can be obtained. In addition, although it may be set in the state where it is widened as necessary, it is not preferable to widen it because it may impair the texture and the like.

As a method for dyeing the woven fabric of the present invention, a general method for dyeing a polyethylene terephthalate fiber woven fabric may be used, but the polytrimethylene terephthalate fiber exhausts the disperse dye even at a temperature about 20 ° C. lower than the polyethylene terephthalate fiber. It has a characteristic that it is easy to perform, and even when dyeing a deep color, sufficient coloring properties can be usually obtained at a low dyeing temperature of about 110 ° C. In the present invention, the dyeing process may be carried out after bleaching or alkali reduction after presetting. If the purpose of the present invention is not impaired in the finishing process after dyeing, finishing processes such as resin processing, softening process, water absorbing process, antistatic process, antibacterial process, water repellent process and enzyme treatment which are usually used for textile processing are not performed. Applicable.

Further, in the case of a woven fabric in which fibers other than the polytrimethylene terephthalate fiber of the present invention are mixed, the fiber may be dyed by a conventional method as long as the effects of the present invention are not impaired. For example, when the regenerated cellulose fiber is used for the warp, it may be dyed by appropriately selecting from the usual immersion method, padding dyeing method such as cold pad batch, print dyeing method and the like. Next, the greige width of the woven fabric for finishing the woven fabric of the present invention to the standardized width is the width obtained by adding the width of the greige shrunk by scouring and the width of the woven fabric after presetting to the standard width. The greige width may be used. Normally, the greige is widened in the range of 5% to 36% with respect to the standard width. The standard width represents a width required for a woven fabric after dyeing and finishing, and is a value that is individually set according to a use to be used. For example, the standard width for typical backing applications is 112 cm (44 inches), 12 cm (12 inches).
2 cm (48 inches), 137 cm (54 inches), 1
52 cm (60 inches). Hereinafter, the present invention will be described with reference to examples.
