Description

工作服work clothes

本发明涉及一种工作服，它由单位面积重量为60-300g/m2和断裂强度＞150N的微细纤维非织造布制成的。The present invention relates to a kind of work clothes, which is made of microfiber non-woven fabric with unit area weight of 60-300g/ m2 and breaking strength>150N.

对工作服的要求是各种各样的。除了以所用材料的断裂强度表示的承载能力外，感兴趣的有好的可加工性和各按其用途小的材料厚度以及好的隔热能力或防尘性，透气性，输湿性和保养性。迄今采用不同纤维混纺的材料作工作服，而它们的组织结构容易散边或纱线移位并由此必须折边。同时机织其料子时，考虑到其强度总要注意织物的运行方向。The requirements for work clothes are various. In addition to the load-carrying capacity in terms of the breaking strength of the materials used, good processability and small material thicknesses depending on the application as well as good thermal insulation or dust protection, air permeability, moisture transport and maintenance properties are of interest . Previously, work clothes were made of materials made of different fiber blends, whose weaves tended to unravel or the threads were displaced and therefore had to be hemmed. At the same time, when weaving its material, always pay attention to the running direction of the fabric in consideration of its strength.

按本发明的目的在于，提供一种断裂强度＞150N价廉物美的工作服及其生产的方法。The object of the present invention is to provide inexpensive work clothes with a breaking strength of >150 N and a method for their production.

本发明的目的是通过一种工作服来实现的，该工作服是由单位面积重量为60-300g/m2和断裂强度＞150N的微细长丝非织造布制成的，其中非织造布由熔融纺丝，经牵伸的和直接铺成纤维网的纤度为1.5至5分特(dtex)的多组份长丝组成，其多组份长丝必要时在予粘合后至少80％分裂成纤度为0.1-0.8分特(dtex)的微细长丝和再将其粘合。本发明的工作服由于长丝不需折边不会出现散边和纱线移位。The object of the present invention is achieved by a kind of overalls, which is made of fine filament non-woven fabric with a weight per unit area of 60-300g/m 2 and a breaking strength > 150N, wherein the non-woven fabric is made of melt-spun Filament, drawn and directly laid into a web, consisting of multicomponent filaments having a denier of 1.5 to 5 decitex (dtex), the multicomponent filaments of which are split to denier by at least 80% after prebonding, if necessary Fine filaments of 0.1-0.8 decitex (dtex) and then bonded. Because the work clothes of the present invention do not need to be hemmed, no frayed edges and yarn displacement will occur.

优选的一种工作服是其中的非织造布由熔融纺丝，气动牵伸的和直接铺成纤维网的纤度为1.5分特(dtex)的多组份长丝形成且其多组份长丝至少80％分裂成纤度为0.1至0.3分特(dtex)的微细长丝并将其进行粘合。其工作服的纤维网中长丝的分布是各自同性的。因此在剪裁工作服的部件时不需考虑机器运行的方向。A preferred type of workwear is one in which the nonwoven fabric is formed from multicomponent filaments of 1.5 decitex (dtex) that are melt spun, pneumatically drawn and directly laid into a web, and that the multicomponent filaments are at least 80% are split into fine filaments with a denier of 0.1 to 0.3 decitex (dtex) and bonded. The distribution of filaments in the fiber web of the overalls is homogeneous. Therefore, it is not necessary to take into account the direction in which the machine is running when cutting the parts of the overalls.

优选的一种工作服是其中的多组份长丝是双组份长丝，它是由两种不相容的聚合物，特别是聚酯和聚酰胺形成。这样的双组份长丝具有良好的分裂成微细长丝的可分裂性并实现最合适的强度与单位面积重量比。同时本发明的工作服由于采用的聚合物和其长丝结构是抗皱的，易洗和快干，即容易保养。A preferred type of work garment is one in which the multicomponent filaments are bicomponent filaments formed from two incompatible polymers, especially polyester and polyamide. Such bicomponent filaments have good splittability into fine filaments and achieve the most suitable ratio of strength to weight per unit area. At the same time, the work clothes of the present invention are wrinkle-resistant due to the polymer used and its filament structure, easy to wash and dry quickly, that is, easy to maintain.

优选的一种工作服是其中多组份长丝具有呈桔子状或也称“馅饼”的多断片结构的横断面，其中所述的断片交替地各含两种不同的聚合物中之一种。除了多组份长丝的桔子状多断片结构外在多组份长丝中不相容聚合物的多断片一排列也可能是“并列”(S/S)的，这尤其是有利于生产卷曲长丝。事实证明多组份长丝中不相容聚合物的这样排列具有非常好的可分裂性。在多组份长丝中“馅饼”断片排列和由此分裂出的微细长丝对本发明工作服的吸湿性有利。A preferred workwear is one in which the multicomponent filaments have a cross-section of an orange-shaped or "pie" multi-segment structure, wherein said segments alternately contain one of two different polymers . In addition to the orange-shaped multi-segment structure of multi-component filaments, the multi-segment-arrangement of incompatible polymers in multi-component filaments may also be "side-by-side" (S/S), which is especially beneficial for the production of crimps filament. Such an arrangement of incompatible polymers in multicomponent filaments has proven to be very splittable. The arrangement of the "pie" segments in the multicomponent filaments and the resulting microscopic filaments contribute to the hygroscopicity of the garments according to the invention.

此外一种优选工作服是其中的至少组成多组份长丝的不相容的聚合物中的一种含有重量百分比至多10％的添加剂，如颜料，永久生效的抗静电剂和/或影响亲水或疏水性能的添加剂。由纺液着色的长丝制成的工作服具有极好的洗涤坚牢度。此外可通过添加剂减少或避免静电荷和改善输湿性，此外改善洗涤性能，即降低洗涤剂消耗和减少干燥时间。Furthermore, a preferred workwear is one in which at least one of the incompatible polymers constituting the multicomponent filaments contains up to 10% by weight of additives, such as pigments, permanent antistatic agents and/or effects on hydrophilicity or hydrophobic additives. Workwear made from dope-dyed filaments has excellent wash fastness. In addition, static charges can be reduced or avoided by additives and moisture transport can be improved, in addition to improving washing performance, ie reducing detergent consumption and reducing drying times.

本发明生产其工作服的方法是，多组份长丝经熔体纺制，经牵伸并直接铺成纤维网，必要时进行予粘合且其非织造布通过高压流体射流粘合，同时分裂成纤度为0.1至0.8分特(dtex)的微细长丝。这样得到的工作服厚度非常均匀，它具有各向同性的纤维分布，无脱层的倾向和以其高模量值为特点。The method for producing the overalls of the present invention is that multi-component filaments are melt spun, drawn and directly laid into a fiber web, pre-bonded if necessary, and its nonwoven fabric is bonded by a high-pressure fluid jet, and simultaneously split Fine filaments with a fibrillation of 0.1 to 0.8 decitex (dtex). The workwear thus obtained is very uniform in thickness, has an isotropic fiber distribution, has no tendency to delaminate and is characterized by high modulus values.

优选生产其工作服的方法，即通过将予粘合的非织造布至少一次在每一面用高压水射流加载，这样使多组份长丝粘合和分裂。用此方法生产的工作服显示良好的表面且其多组份长丝的分裂度＞80％。Preference is given to the method of producing its work clothes by loading the prebonded nonwoven at least once on each side with a high-pressure water jet, so that the multicomponent filaments are bonded and split. Workwear produced in this way exhibited a good surface with a splitting degree of >80% of the multicomponent filaments.

按本发明的工作服为提高其耐磨性优选进行点轧光。为此将分裂和粘合的非织造布通过加热辊引出，其中至少一个辊有凸出的结构，这使长丝相互之间形成逐点的熔融。The work clothes according to the invention are preferably spot calendered in order to increase their wear resistance. For this purpose, the split and bonded nonwoven is passed over heated rolls, at least one of which has a raised structure, which causes the filaments to fuse point by point with one another.

特别优选的是在该方法中的多组份长丝是纺液着色。染料在聚合物纤维中牢固结合导致极好的洗涤坚牢度。It is especially preferred that the multicomponent filaments in the process are dope dyed. The strong incorporation of the dyes in the polymer fibers results in excellent wash fastness.

本发明生产的工作服包括外衣罩衫、围裙、裤子、裙子。The work clothes produced by the present invention include outerwear blouse, apron, trousers, skirt.
