Problems solved by technology

After finishing the surface of the product, Evolon has the same good washability and excellent drape performance as ordinary woven and knitted fabrics. However, the composition of the production line is quite different from the existing production line, and the requirements for raw materials are high, so this technology is adopted The production of non-woven fabrics for clothing has the disadvantages of huge input costs and high product prices

Embodiment 1

[0024] Please refer to figure 1 , a method for producing a garment spunlace nonwoven, comprising the following processes:

[0025] The synthetic fiber (marked as fiber in the figure) is opened, cleaned and carded, and then laid to form an upper fiber web and a lower fiber web, wherein the upper fiber web is formed by straight laying (direct carding), and the lower fiber web is carded and then cross-laid. Of course, the structure of the upper and lower fiber webs can be interchanged, or both are fiber web structures made of cross-laid fibers or fiber web structures made of straight-laid fibers, or even other structures, and the preferred method is adopted here. The cross-lapping method can improve the lateral strength of the finished product.

[0026] The upper fiber net, polyester grid and lower fiber net are stacked successively to form a three-layer composite structure; the polyester grid is added in the middle of the upper and lower fiber nets to play the role of reinforce...

Embodiment 2

[0032] Please refer to figure 2 , a method for producing spunlaced nonwovens for clothing, the difference from Example 1 is that the upper fiber web and the lower fiber web are also made of natural cotton fibers or mixed with natural cotton fibers and synthetic fibers, so in It is necessary to add a degreasing treatment process and a bleaching treatment process between the spunlace treatment and the finishing treatment. Other processes and principles are the same. Of course, natural cotton fiber is the preferred mode among natural fibers here, and when natural absorbent cotton is used, it can be flexibly grasped whether a degreasing process is needed according to the prior art.

[0033] refer to figure 1 , figure 2 , a spunlaced nonwoven fabric for garments, which is produced through Embodiment 1 or Embodiment 2 and other similar methods that can be imagined under the generalization of the previous principles.

[0034] The preferred spunlaced nonwoven fabric for this kin...

Abstract

The invention discloses a spunlaced nonwoven fabric for clothing and a production method and equipment thereof, which relate to the field of the nonwoven fabric. A triple-layered composite structure is formed by an upper layer and a lower layer of fiber meshes which are produced by a polyester mesh and a laying net, and then after spunlaced fixation and post treatment, the spunlaced nonwoven fabric for clothing is produced and has good elasticity, washing resistance, wear resistance and air permeability. The production method only needs to simply remold the existing spunlaced production line, only one polyester mesh uncoil stand is needed to be added, so the spunlaced nonwoven fabric for clothing can be produced, and the reinvestment cost of the equipment is greatly reduced; and the manufacture and the technology are simple and easy to process, and the production cost of the product is low.

Description

technical field [0001] The invention relates to the field of nonwoven fabrics, in particular to a spunlaced nonwoven fabric for clothing, a production method and equipment thereof. Background technique [0002] Non-woven fabrics have many characteristics that woven and knitted fabrics do not have. Such as its short production process, high output, wide range of uses, and diverse sources of raw materials. However, because its repeated washing, tensile strength and drapability are slightly insufficient compared with traditional woven or knitted fabrics, it has great limitations as a clothing fabric. In the past, the use of non-woven fabrics for clothing was limited to certain special areas such as disposable medical protective clothing, disposable underwear and other products. As for using it as a fabric for outdoor pants, jackets, sportswear and other clothing, there will be many problems in front of you. In recent years, with the development of polymer technology, the imp...
