Abstract

A process for treating pantyhose in a cryogenic processor to produce cryogenically treated pantyhose that have enhanced wearing qualities is described. In this regard, one such process, among others, can be broadly summarized by the following steps:reducing the temperature of the pantyhose to between about -80 DEG C and about -240 DEG C over about a 1 to 6 hour time period; holding the temperature of the pantyhose between about -80 DEG C and about -240 DEG C for a 6 to 48 hour time period; and allowing the pantyhose to increase in temperature to about 25 DEG C over a 3 to 48 hour time period. The cryogenic treatment of pantyhose results in enhanced wearing qualities.

Description

Be used to handle the low temperature method of panty hose
Technical field
The present invention relates generally to the quality of panty hose, relates in particular to the method for the durability that is used to strengthen panty hose.
The cross reference of related application
The application requires the right of priority of the 60/305th, No. 787 unexamined U.S. Provisional Application " CYROGENIC PROCESS FOR TREATINGPANTYHOSE " of submission on July 16 calendar year 2001, and its full content is hereby expressly incorporated by reference.
Background technology
Fabric by production of machinery comprises the fabric that is woven into by continuous fibers, for example women socks or the like.Be different from spun yarn, silk fabrics is by weaving of elongating or continuous structure is made.Continuous fibers are characterised in that to have uniform cross section and smooth surface.A difficulty of the silk weaving material of fine needle distance is that suture is easy to reel off raw silk from cocoons.For example, in panty hose, the circumferential weld line that disconnects at the knee place can cause reeling off raw silk from cocoons along stocking length.When panty hose wore and tore, it was subject to horizontal tension influence, and this tension force trends towards weakening and breaking the circumferential weld line, and caused continuous suture to unclamp and break away from.
Especially, when panty hose and other fine fibre fabrics touch nail and other coarse article (for example cabinet angle and dressing corner of table) and other sharp objects, be very easy to running, pierce through, hook is broken, wearing and tearing and damage.Be used to make the nylon and also the possibility weakened and damage of other synthon of panty hose owing to be exposed to heat, sunlight (ultraviolet radiation), rain or body sweat for a long time.When fiber is cut off or damage, will have a negative impact to the integrality of whole fabric, and the damage that causes can involve the peripheral region, cause clothes to pall on usually and effectiveness.
In the past, handle panty hose with anti-running by spraying knitting socks with adhesive material.Yet adhesive material can form visible pattern and look like stain on the socks, and adhesive material can reduce the elasticity of panty hose greatly.
Therefore, a kind of improvement disposal route that is used for panty hose is very useful and needs, and the resistibility of its increase fabric also reduces the possibility of fibre breakage, does not have adverse effect, overcomes aforesaid various shortcoming simultaneously.
Summary of the invention
The invention provides a kind of being used at cryogenic processor processing panty hose to produce the method for passing through sub zero treatment and strengthening the panty hose of wearing quality.In this, this method embodiment can summarize by following steps: in about 1~6 hour time the temperature of panty hose is reduced to approximately between-80 ℃ of peace treaties-240 ℃; Between the temperature of panty hose is maintained at about-80 ℃ of peace treaties-240 ℃ 6~48 hours; And the temperature that makes panty hose in 3~48 hours time is elevated to about 25 ℃.
In another embodiment, said method may further comprise the steps: made the temperature of panty hose be elevated to about 40~80 ℃ in the clock time at about 30~120 minutes; Make the temperature of panty hose be maintained at about 40~80 ℃ about 15~60 minutes; And made the temperature of panty hose drop to about 25 ℃ in the clock time at about 50~120 minutes.
