Definitions

  • This invention relates to the preparation of elastic nonwoven sheets from non-elastic hydroentangled sheets.
  • Elastic fabrics are usually made with rubber or some other elastomeric material incorporated into or attached to a precursor fabric.
  • the precursor fabrics can be traditional textiles or nonwoven fabrics.
  • Other methods of producing elastic nonwovens included imbedding or attaching elastomeric threads, strips, and films. These can be attached by adhesives, thermobonding, lamination, sewing, stitch bonding, etc. However, in all cases, the process is expensive.
  • thermoplastic bonded nonwoven fabrics such as spunbond and carded webs
  • thermo- mechanical methods describe passing a thermally bonded precursor web through an oven at an elevated temperature between the softening temperature and the melting point and applying a draw in the machine direction to transversely consolidate the web, whereby the majority of the fibers are extended and aligned predominantly in the direction of the draw.
  • the fixation of fibers in the longitudinally extended configuration creates a position memory at the thermally bonded points; therefore, the web exhibits recovery when stretched in the transverse direction.
  • these methods require precursor webs that have been subjected to thermo-mechanical bonding or calendering and the treatment temperature has to be lower than the melting point of the fibers. Otherwise, the web would be plasticized, stiff, brittle, and with virtually no elasticity, or worse would cause the web to break in the process.
  • the tensile strength of such a web totally relies on the thermal bonding and the heat and strain treatment aligns the majority of the fibers mostly in the direction of the draw, it causes serious loss of tearing strength in the resultant elastic fabric along the draw direction.
  • the invention is directed to a method for making an elastic fabric by providing a hydroentangled precursor fabric having at least 1% by weight of thermoplastic binder fibers that has lower melting temperature than that of the rest of base fibers; and while heating the precursor fabric to a temperature above the melting point of the binder fibers, drawing the precursor fabric in the machine direction at a ratio sufficient to reduce the width of the precursor by at least 20% and at a strain rate of 10 to 800% per minute, .and then cooling the resultant to ambient temperature to set the resultant web.
  • the invention is directed to an elastic hydroentangled fabric made by the described method and having an extensibility of 100% to 500% in the cross direction and a 30-95% recovery under a 50% elongation, in the cross direction.
  • the figure is a schematic illustration of an apparatus for performing one embodiment of the method of the invention.
  • One object of the present method is to provide a cost-effective thermo-mechanical process of creating an elastic spunlaced fabric without the use of true elastomeric fibers as base fibers.
  • the plasticized binder fibers can serve the bonding purpose in the contacting points and create the position memory for fibers fixed around the contacting points. Since the percentage of binder fibers is low, there is no significant stiffness caused by the high temperature process of this invention.
  • the use of spunlaced nonwoven precursor provides thicker, softer elastic fabrics with a more desirable tearing strength.
  • the precursor fabric is made of predominantly non-elastomeric base fibers such as (poly) ethyleneterephthalate (i.e., polyester), or polyamide staple fibers or a mix of above synthetic fibers with some percentage of non-thermoplastic fibers such as wood pulp, cotton, rayon, lyocell, etc. and then blended with at least about 1% binder fibers and preferably about 5% to 30% binder fibers.
  • the binder fibers are preferably made of thermoplastic fibers such as polypropylene, polyethylene, co-polyester, acrylic, polyamide, polyurethane, and polystryene.
  • the binder can be a bi-component fiber, such as sheath/core, side-by-side, etc.
  • the binder fibers can be bi-component staple fibers having a co-polyester sheath and polyester core or polyethylene sheath and either a polyester or compounded elastomer core.
  • the co-polyester composition can vary depending on the manufacturer of the fiber and the desired attributes, but is commonly composed of the copolymer of poly(ethyle ⁇ e terephthalate) and isophthalate. The percentage of binder fiber is by weight of the fabric.
  • binder fibers By incorporating binder fibers into the fiber web that is further processed into a spunlaced web and then activating these binder fibers in an in line dryer, we have made a fabric which can then be converted into an elastic web.
  • the cross over points of the binder fibers with themselves and/or the base fibers act similarly to the point bonds of a spunbonded fabric.
  • the present invention provides a process of preparing an elastic spunlaced (hydro-entangled), nonwoven web.
  • a precursor web of synthetic and/or wood pulp fibers blended with thermoplastic binder fibers is processed into a web by opening, carding or other suitable web forming processes followed by hydroentanglement (also referred to as spunlacing).
  • the spunlaced web. is subjected to an elevated temperature sufficient to at least partially melt the binder fibers, but not the base fibers making up the fabric. This can be accomplished by a hot air treatment or any other suitable means for achieving the desired elevated temperature.
  • the spunlaced fabric is subjected to a drawing treatment in the machine direction at a drawing ratio sufficient to reduce the web width by more than 20% (preferably in the range of 55-75%) with a strain rate of from 10 to 800 %/min.
  • the drawing ratio can be 5 to 50 %, preferably 10 to 20%.
  • This step of drawing at an elevated temperature can be accomplished either in-line with the precursor web forming process or as a separate off- line process.
  • the method of heating the precursor web is not particularly limited as long as the heat transfer may be accomplished in as short a time as necessary to avoid damage of the web. Heating may be accomplished by radiation or convection. Radiation heating may be carried out by using infrared methods. Convection heating may be carried out by a suitable heating fluid, preferably a gas such as air.
  • an elastic spunlaced fabric 2 is prepared by providing a spunlaced precursor web 1 containing thermoplastic binder fibers, whereby the precursor web is supported by unwinding roll 10.
  • Unwinding roll 10 is rotated around its longitudinal axis whereby the precursor web 1 leaves unwinding roll 10 at a speed A in the machine direction (MD) as indicated by the arrow.
  • the precursor web travels via S-wrap 15 into a heating means 20, through the heating means and from the exit of the heating means via S-wrap 25 to the winding roll 30.
  • S-wrap 25 and winding roll 30 are driven at a speed higher than the unwinding speed A of unwinding roll 10 and S-wrap 15 by a factor of (1+X%).
  • S-wrap 15 comprises rolls 151 and 152.
  • S-wrap 25 comprises rolls 251 and 252.
  • the factor (1+X%) determines the drawing ratio of the precursor web in the process of the present invention.
  • the precursor web is subjected to a drawing treatment in a machine direction at a drawing ratio sufficient to reduce the width by at least 20% and a strain rate within a range of 50 to 800 %/min, at a temperature above the melting point of the binder fibers in order to create in the resultant fabric, elongation at break in the cross direction of greater than about 100% up to 500%.
  • Commercially useful recovery of 15-80% with 50-200% extension can be achieved with the resultant elastic fabrics.
  • the machinery for carrying out the process of the invention is constructed for commercial capacity with an unwinder roll and a winding roll(s) installed in a distance of from 3 to 40 m, preferably about 20-30 m, and a heating device installed between.
  • the unwinder advantageously runs at commercial speed of more than 30 m/min and up to 300 m/min, preferably at least 100 m/min and up to 250 m/min, and a draw ratio of 1% to 30 %, preferably 10-20%, is created by increasing the speed of the winding roll.
  • the strain rate is adjusted to 10 to 800 %/min.
  • the draw ratio relates to the degree of width reduction of the precursor web and the strain rate relates to the speed of the treatment at a fixed draw ratio.
  • the S- wraps 15 and 25 also control the movement of the nonwoven web, as well as serving as the drawing means.
  • the elastic spunlaced web is characterized by a width reduction of
  • the resultant elastic spurtlaced fabric has a thickness of 0.2 mm-3.5mm and a basis weight of 20 to 300 g/m 2 .
  • the present invention further provides products containing the elastic nonwoven web of the present invention that greatly expands the scope of nonwoven substrates available for producing elastic nonwoven fabrics in a very cost effective manner.
  • the subject invention has applications in fields such as consumer goods; cleanrooms; medical face masks, hoods and gloves; substrates for composites and laminates and coatings such as for synthetic leather substrates.
  • the strain rate (%/t) is generally described as a piece of fabric being drawn and extended a certain (X) percentage in a period of time.
  • the extension percentage can be achieved by the speed ratio of winder or S-wrap (25) to unwind or S-wrap (25), and the time period of fabric run through can be calculated by dividing D over the average of unwind speed (A) and winder speed of [(1+X%) A].
  • Speed A is generally expressed in m/ min as follows:
  • the web elasticity is defined by measuring a 5-cm wide x 10-cm long strip along the longitudinal axis as follows: (stretched length - recovered length) / (stretched length - original length).
  • the " melting point is the temperature where a thermoplastic fiber starts to become a liquid.
  • the strip tensile test is a measure of breaking strength and elongation or strain of a fabric when subjected to unidirectional stress. This testing was conducted on a constant rate of strain tester, lnstron Model 1122. In the current examples, strips of fabric 2 inches (50 mm) wide and at least 5 inches (150 mm) long are cut in the machine direction and cross direction of the fabric. Ten specimens per sample were tested to compute an average value. This test is known in the art and generally conforms to the specifications of ASTM Method 5035-95. The results are expressed in pounds to break and percent of elongation before break.
  • elongation means the increase in length of a specimen during a tensile test expressed as a percentage of the original length.
  • extentensibility used is the same as the elongation-at-break measured in the tensile test.
  • Tearing strength is measured by the tongue (single rip) procedure modified from the ASTM 5735 using a rectangular specimen of 2 x 2.5 inches (50 mm x 63.5 mm). Ten (10) specimens are tested per treatment and the results are expressed in pounds.
  • the basis weight of each specimen is computed from the average weight of 10 strip samples or 12 grab samples respectively.
  • Thickness is the average of 10 strip samples or 12 grab samples respectively.
  • the strip samples are measured using a TMI automated thickness tester, with a 2 inch diameter contact area and pressure of 14.7 g/cm 2 .
  • the grab samples were measured using an Ames thickness gauge with a 1-inch diameter contact area and pressure of 7.46 g/cm 2 .
  • the base fibers are polyester staple fibers, commercially available from DAK Americas identified as Dacron(R) Type 612W.
  • the binder fibers are sheath/core co-polyester/polyester staple fibers commercially available from FIT, Incorporated and identified as Type 201.
  • the melting point of the binder fibers is 110 0 C (230T) and the precursor spunlaced fabrics contain 15% binder fibers.
  • Precursors A and E have a basis weight of 1.2 and 1.85 ounce per square yard, respectively.
  • the results of longitudinal draws at ambient temperatures are presented in Table 1 below.
  • Precursors C and D had a basis weight of 0.8 ounce per square yard (27 g/m 2 ).
  • the results of longitudinal draw at elevated temperatures are presented in Table 2 below.
  • the longitudinal draw at elevated temperatures was able to reduce the width up to about 75% and a draw ratio of about 10% was shown sufficient to achieve a 50% width reduction.
  • the width reduction on the resultant example webs was found to be a function of draw and the temperature and the enhancement of the extensibility in the cross direction was also found to result from the draw and the temperature. Further, it was noticeable that the elasticity (recovery after elongation) increased with higher temperatures.
  • Precursor spunlaced fabrics as described above, but with basis weights of either 0.8 or 1.2 oz/yd 2 (27 or 40.7 g/m 2 ) were subjected to various draw ratios at various draw temperatures to achieve the desired width reduction of at least 50%.
  • the examples were then further tested for various elongation and stretch recovery properties. With the treatment of longitudinal draw at an elevated temperature of 330°F, the physical properties of the resultant webs were significantly changed and a commercially valuable elasticity was shown by the elongation of under 300%. The results are presented in Table 4, below.
