Description
【0001】
【発明が属する技術分野】
本発明は、家庭洗濯、業務リネン、テンセル(登録商標)加工等に使用される、高い耐久性を求められる処理袋に関するものである。
【0002】
【従来の技術】
家庭洗濯、業務リネン、テンセルの揉み加工等に使用される処理袋を構成するネットとしては、これまではポリエステルフィラメントを用いたものが一般的に使用されている。
【0003】
【発明が解決しようとする課題】
家庭洗濯、業務リネン等において、顧客毎の区分け、鋭利な角を有するボタン、ファスナー等からの洗濯物の保護、布絡みの防止、洗濯機械からの洗濯物の保護等を目的としたネット地使いの処理袋は従前より広く使用されてきた。しかしながら、機械設備の発達に伴い、洗濯に要する時間や、テンセル加工(揉み加工)に要する時間の短縮(処理能力)は向上の一途を辿りつつある一方で、洗濯物、或いは揉み加工される生地自体の強度は、従前から何等向上しているわけでもなく、また、ポリエステルフィラメントを用いた処理袋自体の強度も、従前から何等向上しているわけでもない為、機械設備の発達だけでは処理時間の短縮等の効果を得る事はできなかった。従って、無理に処理時間の短縮等を狙って、洗濯或いは揉み加工の強さを高めると、より過酷な摩耗状態となり、結果的に処理袋の寿命が短くなり不経済であるばかりか、処理袋を形成するネット自身が毛羽立ち、脱落した毛羽によって洗濯物、或いはテンセル加工生地の品位が著しく低下するといった事が起こり、技術革新を行う上での大きな壁となっていた。また、テンセル加工においては、特に処理袋の寿命不足が問題視されると共に、処理袋に使用されるポリエステル繊維自身が染料で汚染され易く、異なる色の生地を処理する場合、色移り等による生地品位の著しい低下が起こり易い事も、改善すべき大きな課題であった。
本発明者らは、上記従来の課題に鑑み,超高分子量ポリエチレンマルチフィラメントを使用することにより、その素材性能を効率よく反映させた処理袋を提供することを可能とした。
【0004】
【課題を解決するための手段】
則ち、本発明による処理袋は、重量平均分子量が50万以上の超高分子量ポリエチレンからなる10〜4800デニールのマルチフィラメントを50%以上有し,しかも目付重量が下記式を満足する布帛を用いてなるものである。
W≦2n×D0.5
W:網地目付重量(g/m2 )
m2 =長さ 1m(JIS L 1043)×幅 規格掛数(掛/15.15cm)×6.6
D:使用原糸のデニール(d)
n:網脚を構成する糸本数(本)
具体的な態様としてはマルチフィラメントが単糸10デニ−ル以下のフィラメントから構成されたことを特徴とする上記処理袋。
布帛がラッセル網地であることを特徴とする上記処理袋。
マルチフィラメントが下記式で規定する撚係数Kが1以下である撚糸であることを特徴とする上記処理袋。
K=(T×D0.5)/73
K=撚係数
T=撚数(回/インチ)
D=デニール(d)
マルチフィラメントが引張強度が25g/d以上、破断伸度が6%以下、初期弾性率が650g/d以上であることを特徴とする上記処理袋である。
【0005】
以下、詳細に説明する。
本発明で使用される繊維素材は重量平均分子量が50万以上,好ましくは200万以上の超高分子量ポリエチレン繊維であり、10デニール〜4800デニール、好ましくは200〜1200デニールのマルチフィラメントからなる。そしてかかるマルチフィラメントの引張強度は25g/d以上、破断伸度は6%以下、初期弾性率は650g/d以上のものが推奨される。上記マルチフィラメントを50%以上使用して製網もしくは製編織して目的とする処理袋を製造する。
超高分子量ポリエチレンマルチフィラメントの使用量が50%未満である場合、当該用途においてこれまで使用されてきた、ポリエステルフィラメント使いの処理袋に対する初期性能の優位性を確保できないばかりか、前述の耐摩耗性不足からの毛羽に起因する問題点が顕在化してしまうものであり本発明の所期の目的を達成することが困難となる。好ましくは80〜100%の使用量が推奨される。本発明の処理袋は織編物や網地のいずれでもよいが、網地が最も好ましい。網の形態には蛙又等の結節網の他、貫通網等があるが、当該用途においては、節部の大きさ(太さ)が網脚の大きさ(太さ)と同一で、且つ、網目の形態保持性に優れるラッセル網が最も好ましい。更に、この時、前記マルチフィラメントが10dpfより大きいと、結節強度、引掛強度の低下が著しくなり、原糸を編み立てて(随所で折曲げて)使用するラッセル網の性格上、大きな問題となる。故に、使用するマルチフィラメントを構成するフィラメントの単糸デニ−ルは10dデニ−ル以下であることが望ましい。
【0006】
前記網地は、上記マルチフィラメントをそのまま(生糸)か、或いは加撚、混繊、カバリング、仮撚等の糸加工を施したもののいずれを使用してもよいが、実際の製網性を考慮すると、下記式で表される撚係数Kが1以下の撚糸を使用するのが好ましい。
K=(T×D0.5)/73
K=撚係数
T=撚数(回/インチ)
D=デニール(d)
また、処理液の処理袋内への流入、或いは処理袋外への流出効率等を考慮すると、適度な網目を確保する事が極めて重要とされるが、使用する高強力繊維の初期弾性率が高く、破断伸度が非常に小さいという事は、非常に伸びにくい網地であると言え、網地を編み立てる際に、これらを考慮した設計にする事は極めて重要である。従って、本発明においては、下記式表される数値以下の目付重量のラッセル網地となるように編組する事により、適度な網目を形成する事が可能となる。
W≦2n×D0.5
W:網地の目付重量(g/m2)
m2 =長さ 1m(JIS L 1043)×幅 規格掛数(掛/15.15cm)×6.6
D:使用原糸のデニール(d)
n:網脚を構成する糸本数(本)
このWの値が、上記式で規定する値以上となると、処理液の流入、流出効率を低下せしめる事は勿論の事であるが、他にも、網脚の略軸線と網脚を構成する原糸のなす角度がより鈍角となり、網地自身の単位目付重量当たりの引張強力が著しく低下する事となり、素材性能を十分に活かしていない形となる。従って、本発明においては網地の目付重量を規定する事により、繊維性能を十分に活かし、且つ、処理効率を低減する事なく、高い耐久性と耐汚染性を有する処理袋の提案を可能とするものである。
好ましくはW≦1.9n×D0.5である。

【発明の効果】
本発明によると、被洗濯物を傷めずに、短時間洗濯ができ、しかも耐久性に優れた家庭洗濯や業務リネンおよびテンセル(登録商標)の揉み加工等に好適な処理袋を提供することを可能とした。[0001]
[Technical field to which the invention belongs]
The present invention relates to a processing bag which is used for home laundry, business linen, Tencel (registered trademark) processing and the like and which requires high durability.
[0002]
[Prior art]
As a net constituting a processing bag used for home washing, business linen, tencelle stencil processing, etc., a net using a polyester filament has been generally used.
[0003]
[Problems to be solved by the invention]
In home laundry, business linen, etc., net use for the purpose of sorting by customer, protection of laundry from buttons with sharp corners, fasteners, prevention of fabric entanglement, protection of laundry from washing machines, etc. The processing bag has been used more widely than before. However, with the development of machinery and equipment, the time required for washing and the shortening of the time required for tencel processing (scumming) (processing capacity) are steadily improving, while the laundry or the scoured fabric The strength of the machine itself has not been improved at all, and the strength of the treatment bag itself using polyester filament has not been improved at all. It was not possible to obtain effects such as shortening. Therefore, if the strength of washing or scumming processing is increased with the aim of forcibly shortening the processing time, it becomes a more severe wear state, resulting in a shorter processing bag life and uneconomical processing bag. The net itself forming the hair fuzzes and the fluff that falls off significantly reduces the quality of the laundry or tencel processed fabric, which has been a major barrier to technological innovation. In addition, in Tencel processing, the shortage of the life of the treatment bag is regarded as a problem, and the polyester fiber itself used in the treatment bag is easily contaminated with a dye. It was also a major issue to be improved that a marked drop in quality was likely to occur.
In view of the above-mentioned conventional problems, the present inventors have made it possible to provide a processing bag that efficiently reflects the material performance by using an ultrahigh molecular weight polyethylene multifilament.
[0004]
[Means for Solving the Problems]
That is, the treatment bag according to the present invention uses a fabric having 50% or more of multifilaments of 10 to 4800 denier made of ultrahigh molecular weight polyethylene having a weight average molecular weight of 500,000 or more and having a weight per unit weight satisfying the following formula. It will be.
W ≦ 2n × D 0.5
W: Net weight per unit area (g / m 2 )
m 2 = Length 1 m (JIS L 1043) x Width Standard hook (15/15 cm) x 6.6
D: Denier of raw yarn used (d)
n: Number of yarns constituting the net legs (number)
As a specific embodiment, the treatment bag is characterized in that the multifilament is composed of filaments of 10 denier or less of single yarn.
The treatment bag, wherein the fabric is a Russell net.
The above-mentioned processing bag, wherein the multifilament is a twisted yarn having a twist coefficient K defined by the following formula of 1 or less.
K = (T × D 0.5 ) / 73
K = twisting coefficient T = twisting number (times / inch)
D = denier (d)
The multi-filament has a tensile strength of 25 g / d or more, an elongation at break of 6% or less, and an initial elastic modulus of 650 g / d or more.
[0005]
Details will be described below.
The fiber material used in the present invention is an ultrahigh molecular weight polyethylene fiber having a weight average molecular weight of 500,000 or more, preferably 2 million or more, and is composed of multifilaments of 10 denier to 4800 denier, preferably 200 to 1200 denier. It is recommended that the multifilament has a tensile strength of 25 g / d or more, a breaking elongation of 6% or less, and an initial elastic modulus of 650 g / d or more. Using the multifilaments of 50% or more, netting or knitting is performed to produce the intended treatment bag.
When the amount of ultra high molecular weight polyethylene multifilament used is less than 50%, not only the superiority of the initial performance over the treatment bag using polyester filament that has been used in the application can be secured, but also the above-mentioned wear resistance. The problem caused by the fluff from the shortage becomes obvious, and it is difficult to achieve the intended purpose of the present invention. A use amount of 80 to 100% is recommended. The treatment bag of the present invention may be woven or knitted fabric or mesh, but mesh is most preferred. In the form of the net, in addition to a knotted net such as a ridge or the like, there is a penetrating net, etc. In this application, the size (thickness) of the node is the same as the size (thickness) of the net legs, and The Russell network, which is excellent in mesh shape retention, is most preferable. Further, at this time, if the multifilament is larger than 10 dpf, the knot strength and the catching strength are remarkably lowered, and this causes a serious problem in the nature of the Russell network used by knitting the raw yarn (bending at any place). . Therefore, the single yarn denier of the filament constituting the multifilament to be used is desirably 10 d denier or less.
[0006]
As the netting, either the above-mentioned multifilaments (raw yarn) may be used as they are, or those subjected to yarn processing such as twisting, blending, covering, false twisting, etc., but considering the actual netting properties Then, it is preferable to use a twisted yarn having a twist coefficient K represented by the following formula of 1 or less.
K = (T × D 0.5 ) / 73
K = twisting coefficient T = twisting number (times / inch)
D = denier (d)
In addition, considering the inflow efficiency of the processing solution into the processing bag or the outflow efficiency to the outside of the processing bag, it is extremely important to secure an appropriate mesh, but the initial elastic modulus of the high strength fiber used is The fact that it is high and the elongation at break is very small can be said to be a net that is very difficult to stretch, and it is extremely important to design in consideration of these when knitting the net. Therefore, in the present invention, it is possible to form an appropriate mesh by braiding so as to be a Russell network with a weight per unit weight equal to or less than the numerical value represented by the following formula.
W ≦ 2n × D 0.5
W: Net weight of net (g / m 2 )
m 2 = Length 1 m (JIS L 1043) x Width Standard hook (15/15 cm) x 6.6
D: Denier of raw yarn used (d)
n: Number of yarns constituting the net legs (number)
When the value of W is equal to or greater than the value specified by the above formula, it is a matter of course that the inflow / outflow efficiency of the processing liquid is lowered. The angle formed by the raw yarn becomes more obtuse, and the tensile strength per unit weight of the netting itself is remarkably lowered, so that the material performance is not fully utilized. Therefore, by prescribing the basis weight of the netting in the present invention, it is possible to propose a treatment bag having high durability and stain resistance without fully utilizing the fiber performance and reducing the treatment efficiency. To do.
Preferably, W ≦ 1.9n × D 0.5 .
